[Biomechanical significance of the acetabular roof and its reaction to mechanical injury].
INTRODUCTION: The introduction of morphometry into the quantitative analysis of the bone system and functional adaptation of acetabulum to mechanical damages and injuries enabled a relatively simple and acceptable examination of morphological acetabular changes in patients with damaged hip joints. Measurements of the depth and form of acetabulum can be done by radiological methods, computerized tomography and ultrasound (1-9). AIM OF STUDY: The aim of the study was to obtain data on the behaviour of acetabular roof, the so-called "eyebrow", by morphometric analyses during different mechanical injuries. METHOD: Clinical studies of the effect of different loads on acetabular roof were carried out in 741 patients. Radiographic findings of 400 men and 341 women were analysed. The control group was composed of 148 patients with normal hip joints. Average age of the patients was 54.7 years and that of control subjects 52.0 years. Data processing was done for all examined patients. RESULTS: On the basis of our measurements the average size of female "eyebrow" ranged from 24.8 mm to 31.5 mm with standard deviation of 0.93 and in men from 29.4 mm to 40.3 mm with standard deviation of 1.54. The average size in the whole population was 32.1 mm with standard deviation of 15.61. Statistical analyses revealed high correlation coefficients between the age and "eyebrow" size in men (r = 0.124; p < 0.05); it was statically in inverse proportion (Graph 1). However, in female patients the correlation coefficient was statistically significant (r = 0.060; p > 0.05). The examination of the size of collodiaphysial angle and length of "eyebrow" revealed that "eyebrow" length was in inverse proportion to the size of collodiaphysial angle (r = 0.113; p < 0.05). The average "eyebrow" length in relation to the size of collodiaphysial angle ranged from 21.3 mm to 35.2 mm with standard deviation of 1.60. There was no statistically significant correlation between the "eyebrow" size and Wiberg's angle in male (r = 0.049; p > 0.05) and female (r = 0.005; p > 0.05) patients. The "eyebrow" length was proportionally dependent on the size of the shortened extremity in all examined subjects. This dependence was statistically significant both in female (r = 0.208; p < 0.05) and male (r = 0.193; p < 0.05) patients. The study revealed that fossa acetabuli was forward and downward laterally directed. The size, form and cross-section of acetabulum changed during different loads. Dimensions and morphological changes in acetabulum showed some but unimportant changes in comparison to that in the control group. These findings are graphically presented in Figure 5 and numerically in Tables 1 and 2. DISCUSSION: The study of spatial orientation among hip joints revealed that fossa acetabuli was forward and downward laterally directed; this was in accordance with results other authors (1, 7, 9, 15, 18). There was a statistically significant difference in relation to the "eyebrow" size between patients and normal subjects (t = 3.88; p < 0.05). The average difference of "eyebrow" size was 6.892 mm. A larger "eyebrow" was found in patients with normally loaded hip. There was also a significant difference in "eyebrow" size between patients and healthy female subjects (t = 4.605; p < 0.05). A larger "eyebrow" of 8.79 mm was found in female subjects with normally loaded hip. On the basis of our study it can be concluded that the findings related to changes in acetabular roof, the so-called "eyebrow", are important in diagnosis, follow-up and therapy of pathogenetic processes of these disorders.

Stability after endoscopic forehead surgery using single-point fascia fixation.
BACKGROUND: With endoscopic forehead rejuvenation, most surgeons use at least two points of fixation for each eyebrow, often including some type of bone fixation, to achieve the aesthetic goal of lasting repositioning of the eyebrows and elimination of frown lines. In this prospective study, short-term and 1-year postoperative changes in the position of the eyebrows following extensive release of eyebrow-retaining ligaments and use of single-point fascial suture (without bone fixation) were objectively evaluated. METHODS: Front-view, life-size photographs of 48 patients undergoing endoscopic forehead surgery for treatment of migraine headaches were analyzed preoperatively and 1 and 12 months postoperatively. The distance of the caudal portion of each eyebrow from a horizontal line passing through the medial canthi was measured at three levels: (1) the lateral canthus, (2) midpupil on a straight gaze, and (3) medial canthus. RESULTS: Statistical analysis revealed a significant elevation of the eyebrows at each of these three reference points when preoperative and 1-month postoperative data were compared (p = 0.001). Twelve months postoperatively, the eyebrows remained significantly elevated at each of the three reference points on both the left (p = 0.001) and right (p = 0.001) sides. Comparison of data at 1 and 12 months postoperatively did not show any statistically significant difference (p = 0.1 to 0.9 at the three levels), indicating that the eyebrow elevation was maintained. CONCLUSIONS: The authors conclude that wide release of the eyebrow-retaining ligaments with single-point fascial fixation is an effective method for elevation of the eyebrows, and that bone fixation should be used when an alteration of eyebrow arch form or correction of eyebrow asymmetry is indicated.

Browplasty and browpexy: an adjunct to blepharoplasty.
Surgical approaches to the eyelids and eyebrows have been refined by application of their anatomy and appreciation of their pathophysiology. Sexual variations in eyebrow appearance can be attributed in part to the eyebrow fat pad. In females, the eyebrow is generally arched and above the level of the supraorbital rim. The male eyebrow is flatter and at the level of the supraorbital rim. The eyebrow fat pad is more prominent in the male, producing a fuller appearance in the lateral brow area. Many women are concerned about the flatter, full lateral brow, which assumes a masculine quality. The authors describe a surgical technique that permits identification of the brow fat pad and then the ability to debulk the eyebrow (browplasty). In addition, the brow can be elevated by internal plication suture to physically elevate the eyebrow (browpexy). This procedure is designed to utilize an eyelid crease incision, and it reduces the indications for more involved procedures to eliminate brow ptosis, such as midforehead or coronal approaches.

Mesh lift: a new procedure for long-lasting results in brow lift surgery.
BACKGROUND: Prevention of recurrent eyebrow ptosis is the greatest challenge in brow lift surgery today. In this article, the author describes a new surgical procedure to provide long-lasting results in brow lift surgery. METHODS: Over 7 years, this new technique was used in 37 patients. Except for four, all patients were women aged 22 to 57 years. In this procedure, a polypropylene mesh strap is used as a suspender to maintain the elevated position of the eyebrow. The mesh suspender is placed in a subgaleal tunnel that is created between a limited temporal scalp incision and a classic upper blepharoplasty incision. The distal end of the mesh is sutured to the undersurface of the upper orbital part of the orbicularis oculi muscle, and the proximal end is fixed to the periosteum at the temporal region after a desired eyebrow position is obtained by traction of the mesh suspender superolaterally. RESULTS: The polypropylene mesh was tolerated well in all patients. No complication related to foreign body reaction was encountered. During 6 months to 4 years of follow-up, none of the patients experienced recurrent eyebrow ptosis. The long-term results revealed a long-lasting, almost permanent eyebrow elevation in all patients. CONCLUSIONS: This new technique seems to be useful in prevention of recurrent eyebrow ptosis following brow lift surgery. The author suggests that, after its integration with reoperative tissue, the mesh suspender becomes an artificial suspensory aponeurosis that provides stable fixation to maintain the elevated position of the eyebrow. This is considered to be the main reason for the excellent long-lasting results obtained in the current clinical study.

Ocular adnexal asymmetry in models: a magazine photograph analysis.
BACKGROUND: Symmetry of facial features often correlates with a perception of physical attractiveness, and ophthalmologists are sometimes consulted by patients for eyelid, eyebrow, or orbital asymmetry. Our objective was to determine the prevalence of ocular adnexal asymmetry among people generally regarded as attractive. METHODS: The mean width of the horizontal palpebral fissure (MHPF) for both men and women was determined in 40 adult volunteers. Then unobscured, head-on photographs of models looking in the primary position were digitally scanned from popular magazines. Eyelid height, eyelid folds, eyebrow height, medial canthus to midline distance, pupil to midline distance, and orbital dystopia measurements were made. After the measurements from the models were scaled to size by factoring with the MHPF obtained from the volunteers, the results were analyzed by paired samples t test for right-left asymmetry of the ocular adnexal measurements. We also examined for antimongoloid slant in the models. RESULTS: The MHPF of the volunteers was 27+/-1.3 mm for women and 29.6+/-2.0 mm for men. Of 102 magazine photographs analyzed, 55 were women and 47 men. As a group, the models showed a statistically significant asymmetry (p<0.05) in the horizontal fissure width, upper central lid fold, upper temporal lid fold, central eyebrow height, temporal eyebrow height, medial canthal to midline distance, pupil to midline distance, and orbital dystopia. The female models had more eyebrow asymmetry. The male models had more asymmetry at the horizontal fissure and with orbital dystopia. Two male models also had a unilateral antimongoloid slant. INTERPRETATION: Small to moderate amounts of eyelid, eyebrow, and orbital asymmetry were observed in faces generally perceived as attractive. This fact should be considered during preoperative discussions with patients considering oculoplastic surgery.

Multiple color changes following laser therapy of cosmetic tattoos.
OBJECTIVE: To emphasize the wisdom of small test areas when treating cosmetic tattoos and the need for multiple laser systems. METHODS: A 48-year-old woman requested removal of permanent makeup (cosmetic tattoos) of her eyebrows and around her lips. Physical examination revealed a brown tattoo of both eyebrows and dark red lip liner around both lips. A test area was performed on the red tattoo of the lips. A frequency-doubled Nd:YAG laser (532 nm, 2.0 J/cm2, 2 mm spot size) was used for the lip area, while the same laser at 1064 nm, 3.9 J cm2, 2 mm spot size was utilized for the eyebrows. The lip area immediately turned black. The patient returned for follow-up 1 month later; the black ink on the lip was treated with the same laser at 1064 nm, 3 mm spot size, 4.2 J/cm2, with satisfactory resolution in two monthly treatments. Both brown eyebrow turned bright orange and were treated with 532 nm, 3 mm, 3.0 J/cm2. One month later the eyebrows were a mixture of yellow ink and dark green. The yellow area was treated with 532 nm, 3 mm, 2.3 J/cm2, while the dark green was treated with the 1064 nm, 3 mm spot size, 4.2 J/cm2. One month later little improvement was noted, so Q-switched ruby laser at 694 nm, 6 mm spot size, 16 J/cm2 was utilized. An additional four monthly treatments were given utilizing a combination of both ruby and 532 nm ND:YAG lasers for green and yellow pigment, respectively. RESULTS: Significant but incomplete resolution of the tattoo ink was achieved. CONCLUSION: Multiple laser systems are needed to remove cosmetic tattoos. Test areas must be done before treatment.

Long-term follow-up study of browlift for treatment of facial paralysis.
Browlift for patients with irreversible paralysis of the frontalis muscle was evaluated in a review of 40 patients who had undergone follow-up studies for durations of more than 3 years. The procedure consists of a lazy S-shaped excision above the upper border of the eyebrow and upward fixation of the lower skin margin. The results were as follows: (1) The percentage of patients for whom symmetrical positioning of the eyebrow was achieved was 65%. (2) The greater the preoperative severity of ptosis, the more often did recurrence occur. (3) Recurrence progressed rapidly during the first postoperative year, but thereafter recurrence was seen only in those patients in whom the affected eyebrow was still in a position higher than its counterpart. (4) No relationship could be seen between age at the time of surgery and postoperative position of eyebrow. (5) Improvement in contraction of the visual field was seen in 85% of patients postoperatively, and complaints were eliminated in 50%. (6) Careful preservation of the sensory nerve is required. (7) The postoperative scar was acceptable. This procedure is a simple and effective method of correction of paralytic ptosis. Although a degree of skill is required to obtain satisfactory results and a surgical scar remains at the upper border of the eyebrow, the advantages of the procedure surpass its disadvantages. It is believed that this method should be used more often in the treatment of facial paralysis.

Muscles that act on glabellar skin: a closer look.
The coronal incision forehead lift became a component of the face-lift procedure 35 years ago and increased the cosmetic benefit for the facial aesthetic surgery patient. Later, this enhanced cosmetic effect achieved from eyebrow resuspension was complemented by treatment of the glabellar skin lines by modifying corrugator supercilii and procerus muscle function through the same coronal incision. In recent years, newer procedures for treating the corrugator supercilii and procerus muscles by using endoscopy or limited incision techniques have eliminated the need for the coronal incision. With these newer techniques has come a renewed interest in the surgical anatomy of the muscle complex that acts on glabellar skin. This study was designed to examine the current understanding of the anatomy of these muscles and to resolve misconceptions and controversy concerning them. Fresh cadaver dissections and simulated muscle action studies done on the glabellar musculature of four specimens were correlated with nerve blockade studies performed in 10 subjects on the temporal and zygomatic branches of the facial nerve. The presence of the depressor supercilii muscle as a distinct entity was confirmed. The little-appreciated oblique head of the corrugator supercilii muscle was identified. The conclusions from this study suggest that the transverse head of the corrugator supercilii muscle produces the vertical component of the glabellar skin line and also contributes to the formation of the oblique component of the glabellar skin line. The oblique head of the corrugator supercilii muscle, the depressor supercilii muscle, and the medial head of the orbital portion of the orbicularis oculi muscle all appear to depress the medial head of the eyebrow and contribute to the formation of the oblique glabellar skin line. The nerve block study provided evidence that the zygomatic branch of the facial nerve supplies the three medial eyebrow depressor muscles, which opens the possibility for future nerve ablation techniques to control the action of the medial eyebrow depressor muscle group. This nerve block study also supports the concept of "physiologic" elevation of the medial eyebrow as an effective component of foreheadplasty.

Blepharoplasty: when to combine it with brow, temple, or coronal lift.
Some patients coming for esthetic blepharoplasty should have one of three supplemental procedures performed to elevate or change the position of the eyebrows. The most precise eyebrow alterations are effected with brow lifting procedures, but these may produce adverse scarring. The temple lift may be employed to draw the lateral part of the eyebrow upward and laterally. Drooping of the central part of the eyebrow requires a frontal or coronal lift or an eyebrow lift. Additional guides to the selection and combination of the procedures are provided.

Differences in facial expressions of four universal emotions.
The facial action coding system (FACS) was used to examine recognition rates in 105 healthy young men and women who viewed 128 facial expressions of posed and evoked happy, sad, angry and fearful emotions in color photographs balanced for gender and ethnicity of poser. Categorical analyses determined the specificity of individual action units for each emotion. Relationships between recognition rates for different emotions and action units were evaluated using a logistic regression model. Each emotion could be identified by a group of action units, characteristic to the emotion and distinct from other emotions. Characteristic happy expressions comprised raised inner eyebrows, tightened lower eyelid, raised cheeks, upper lip raised and lip corners turned upward. Recognition of happy faces was associated with cheek raise, lid tightening and outer brow raise. Characteristic sad expressions comprised furrowed eyebrow, opened mouth with upper lip being raised, lip corners stretched and turned down, and chin pulled up. Only brow lower and chin raise were associated with sad recognition. Characteristic anger expressions comprised lowered eyebrows, eyes wide open with tightened lower lid, lips exposing teeth and stretched lip corners. Recognition of angry faces was associated with lowered eyebrows, upper lid raise and lower lip depression. Characteristic fear expressions comprised eyes wide open, furrowed and raised eyebrows and stretched mouth. Recognition of fearful faces was most highly associated with upper lip raise and nostril dilation, although both occurred infrequently, and with inner brow raise and widened eyes. Comparisons are made with previous studies that used different facial stimuli.

Dispelling the myth of the required high hairline in follicular unit hair transplantation.
BACKGROUND: Hair restoration surgeons have historically taught that the hairline should be placed high on men undergoing hair restoration surgery. OBJECTIVE: To evaluate the position of the anterior-most aspect of the frontal forelock on men experiencing type III-V male pattern baldness. METHODS: Twenty men, ages 20-46 years, with type III-V male pattern baldness were evaluated for the distances between the chin to nose, nose to eyebrows, and eyebrows to frontal forelock. RESULTS: The mean distance from chin to nose was 6.96 cm. The mean distance from nose to eyebrows was 6.55 cm. The mean distance from eyebrows to hairline was 6.8 cm. The distance from chin to hairline was 20.3 cm. Therefore the eyebrows to hairline distance was 33.4% of the whole. CONCLUSION: When using follicular transplantation, it may be appropriate at times to divide the face into thirds at the time of hairline development.

A controlled quantitative study of facial expression in Parkinson's disease and depression.
A microcomputer-based approach to the quantification of facial expression was used to measure and compare the smiling behavior of a group of Parkinson's disease sufferers, a group of patients with major depression, and a control group of comparable age. Subjects were asked to view a series of amusing slides and their expressions were recorded. The most animated smile for each subject was chosen for analysis and scores on 12 computer-generated measures were obtained using the Facial Expression Measurement program. These measures are end-lip measure, mouth width measure, mouth-opening measure, mid-top measure, mid-lower lip measure, top lip-thickness measure, lower lip-thickness measure, eye-opening measure, top eyelid/iris intersect measure, lower eyelid/iris intersect measure, inner eyebrow measure, and mid-eyebrow measure. The depressed group differed significantly from the other groups, with higher scores on end-lip measure, mid-top lip measure, and mid-eyebrow measure. All subjects completed the Levine-Pilowsky Depression Questionnaire. The depressed patients obtained higher depression scores than the parkinsonian group, who in turn had significantly higher depression scores than the control group. The depression score was correlated with end-lip measure, mouth width measure, mid-top lip measure, eye-opening measure, and mid-eyebrow measure in the population as a whole. A significant negative correlation emerged between the depression score and mid-eyebrow measure in the depressed group. Both the depressed group and the parkinsonian group were found to smile significantly less often during the slide session when compared with the control group. These results are discussed in the light of earlier findings.

Topographic anatomy of the eyelids, and the effects of sex and age.
AIMS: To describe the effects of sex and age on eyeball, eyelid, and eyebrow position. METHODS: A cross sectional cohort study was performed in which both eyes of 320 normal subjects aged between 10 and 89 years were included. Of each 10 year age cohort, there were 20 men and 20 women. Frontal, as well as lateral, slides were taken of both eyes. On projected slides, a reference line through the medial canthi and vertical lines through the pupil centre and the lateral canthus were constructed. Using these lines, we measured the size of the horizontal eyelid fissure, the distance from the reference line to the pupil centre and to the lateral canthus, the distance between the pupil centre and the upper and lower eyelid margin, and the distance between the upper eyelid margin and the skin fold and eyebrow. On lateral slides, the distance between the lateral canthus and the anterior corneal surface was measured. RESULTS: Between the ages of approximately 12 and 25 years, the horizontal eyelid fissure lengthened 3 mm, while the position of other eyelid structures remained virtually unchanged. Between the average ages of 35 and 85 years, the horizontal eyelid fissure gradually shortened again by about 2.5 mm. Meanwhile, the distance between the lateral canthal angle and the anterior corneal surface decreased almost 1.5 mm. Aging caused an increase of the distance between the pupil centre and the lower eyelid of about 1 mm in men, and 0.5 mm in women. Aging also caused a higher skin crease and raised eyebrows in men and women, but it did not affect the position of the pupil centre and the lateral canthus. Men showed an 0.7 mm larger horizontal eyelid fissure than women. In women, however, the eyebrows were situated about 2.5 mm higher than in men. CONCLUSION: Aging mainly affects the size of the horizontal eyelid fissure, which lengthens by about 10% between the ages of 12 and 25, and shortens by almost the same amount between middle age and old age. Aging causes sagging of the lower eyelid, especially in men, and a higher skin fold and eyebrow position in both sexes. Aging does not affect the position of the eyeball proper, or of the lateral canthus.

Comparison of mouse bioassay and immunoprecipitation assay for botulinum toxin antibodies.
OBJECTIVE: To compare a recently developed immunoprecipitation assay (IPA) to the mouse protection bioassay (MPB), currently considered the "gold standard", for detecting antibodies against botulinum toxin A (BTX-A) and to correlate these assay results with clinical responses to BTX-A injections. METHODS: MPB and IPA assays were performed on serum samples from 83 patients (38 non-responders, 45 responders) who received BTX-A injections. Six non-responders had serum tested on two separate occasions. Some patients also received a "test" injection into either the right eyebrow (n=29) or right frontalis (n=19). RESULTS: All patients antibody positive (Ab+) by MPB were also Ab+ by IPA, whereas an additional 19 patients (17 with reduced or no clinical response) who were MPB Ab- were Ab+, with low titres, by IPA. Two of these 19 patients (non-responders) were initially MPB Ab- but later became MPB Ab+. Similar to previous studies, the sensitivity for the MPB was low; 50% for clinical, 38% for eyebrow, and 30% for frontalis responses whereas the IPA sensitivity was much higher at 84% for clinical (p<0.001), 77% for eyebrow (p=0.111, NS) and 90% for frontalis responses (p<0.02). The IPA specificity was 89% for clinical, 81% for eyebrow, and 89% for frontalis responses, whereas the MPB specificity was 100% for all three response types, which were all non-significant differences. CONCLUSIONS: Both assays had high specificity although the sensitivity of the IPA was higher than the MPB. In addition, the IPA seems to display positivity earlier than the MPB, and as such, it may prognosticate future non-responsiveness. Eyebrow and frontalis "test" injections correlated well with clinical and immunological results and are useful in the assessment of BTX non-responders.

Browlifting with thread: the technique without undermining using minimum incisions.
The position of the eyebrows exerts great influence over the upper eyelids, both in terms of skin excess as well as in the overall aesthetics of the lid/orbit region. Based on the need to associate the treatment of the eyelids with that of the eyebrows, the author developed an essentially simple surgical technique for browlifting. Through minimal incisions in the scalp and in the superior margin of the eyebrow, an anchor is made and traction is exerted with 00 cotton thread, without undermining in the frontal region, exception made by the thread line which is subgaleal. The main difference between this and other techniques is its use of the glide of the eyebrow over deep soft tissues, without the necessity of undermining. The follow-up ranged from 6 to 16 months, during which the lift remained at acceptable levels in most patients, while in a few cases it dropped down a little. This procedure was well accepted by the patients, making it a good alternative for the treatment of brow ptosis.

The influence of larger subcutaneous blood vessels on pulse oximetry.
OBJECTIVE: Recent studies have renewed interest in reflectance pulse oximetry, specifically for monitoring the patient's forehead. Blood circulation on the forehead immediately above the eyebrow is fed by arteries that branch from the internal carotid artery and lack the vasoconstrictor response present in more peripheral regions. Some investigators question, however, the reliability of monitoring SpO2 on the forehead due to prior reported inaccurate readings with reflectance sensors. The present study evaluates pulse oximetry accuracy when reflectance sensors are placed over potentially pulsing or moving larger arterial vessels, or over more homogeneous microvasculature devoid of larger subcutaneous vessels. METHODS. Ten healthy adult volunteers were fitted with reflectance pulse oximetry sensors and exposed to a controlled desaturation to 70%. Sensors were placed immediately above the left and right eyebrows as well as over the temple. Additionally, numerical modeling was used to simulate light signals and photon migration through a homogeneous tissue bed with an added static or dynamic artery. RESULTS: Sensors placed above the eyebrows tracked one another with significantly better accuracy than when comparing temple with the brow placement (RMS of the Differences = 1.12% vs. 4.24%, respectively). Photon migration simulations indicate that the detected light bypasses the interior of larger vessels, while vessel presence affects the red and IR light pulse amplitudes independent of SaO2. CONCLUSIONS: Placement of reflectance pulse oximetry sensors directly over larger cardio-synchronously pulsing or moving vasculature can significantly degrade SpO2 reading accuracy. Reflectance sensors placed low on the forehead directly over the eyebrow and slightly lateral to the iris appear to avoid such vasculature and provide consistent and accurate estimates of SaO2.
