Nasal alar reconstruction: a critical analysis using melolabial island and paramedian forehead flaps.

OBJECTIVES: To qualitatively and quantitatively describe aesthetic and functional outcomes following Mohs ablative surgery involving the alar subunit, using a paramedian or subcutaneous melolabial island flap. STUDY DESIGN: Retrospective review. METHODS: A single surgeon's results in 38 consecutive patients were analyzed. Objective measures (alar rim thickness, donor scar width and length), subjective assessment (seven aesthetic parameters) by three academic otolaryngologists, and patient satisfaction questionnaires were evaluated. Student t test was used to ascertain statistically significant differences between reconstructive groups. RESULTS: Questionnaire results demonstrate a significant (P = .026) difference in donor site rating favoring melolabial group responses. Objective scar measurements and subjective ratings of textural quality and alar notching also favored melolabial reconstructions. CONCLUSIONS: More favorable aesthetic and functional outcomes are seen with single subunit cutaneous alar defects reconstructed with the melolabial island flap than with deep composite or extensive unilateral nasal defects reconstructed with the paramedian forehead flap.

History of total nasal reconstruction with particular emphasis on the folded forehead flap technique.

The history of plastic surgery is identified throughout the centuries with the history of rhinoplasty. The Indian Koomas first and later the Italian surgeons found valid solutions to the problems caused by partial loss of the nasal pyramid. However, the idea of rebuilding, with a single forehead flap, the tip and columella and providing at the same time a lining of skin for the newly formed nose goes back to the middle of the nineteenth century. The Italian Natale Petrali (1842) and the Germans Johann Friedrich Dieffenbach (1845) and Ernst Blasius (1848) contend for precedence in carrying out this important procedure still used today, which, barring postoperative contracture, represented a great advance in successful total rhinoplasty.

The brown forehead ring: a pattern of facial pigmentation.

The brown forehead ring (linea fusca), a distinctive but infrequently recognized pattern of facial pigmentation, is described. The history of this sign is recounted. In modern times it seems to be associated with other well recognized patterns of facial pigmentation, chemical photosensitizers and excessive sun exposure. Three cases in adult males are described and the different aetiologies illustrated.

Blood pressure reactivity and perception of pain during the forehead cold pressor test.

The relationship between blood pressure reactivity and the perception of pain was examined during a series of three forehead cold pressor tests given every other day to a group of 18 male college students. Subjects classified as high reactors on the basis of peak increases in mean blood pressure during cold pressor tests perceived the cold pressor stimulus as more painful than subjects classified as low reactors. The propensity to rate the cold pressor stimulus as painful was positively correlated with the individual level of blood pressure reactivity (baseline-free partial r = .62). Intra-individual correlations between pain and blood pressure responses were unrelated to subjects' reactivity status. Across the 3-min test, correlations between pain and blood pressure reactivity (with the effects of baseline blood pressure levels partialled out) were significant only during periods when levels of responses were relatively high. The heart rate responses were unrelated to pain ratings. Generalizability theory was applied to the analysis of temporal stability of cold pressor reactions. Both blood pressure and pain responses were highly reproducible across three sessions, appearing to express stable individual differences. The efficacy of 800 mg oral ibuprofen in controlling the cold pressor pain was also tested. Analgesic activity of the drug during the cold pressor test could not be demonstrated.

Lipids in forehead vernix from newborn infants.

Neutral lipids in forehead vernix from newborn infants of various gestations were analysed by gas chromatography. Vernix collected from pre-term (less than 37 weeks) infants differed markedly from that collected from near-term (less than or equal to 37 weeks) infants. The principle difference was a increase in the content of squalene relative to other lipids in vernix from near-term infants. This change indicated a surge in fetal sebaceous gland function at about 37 weeks gestation.

Cardiovascular and perceptual effects of reporting pain during the foot and forehead cold pressor tests.

In research involving the cold pressor test, a tacit presumption is often made that reporting pain during stimulation is not in itself reactive. This study examined whether, for the foot and forehead cold pressor tests, activities involved in reporting pain may affect (a) the evoked pattern of cardiovascular response, and (b) the magnitude of self-perceived pain. In 40 normotensive college men, increases in systolic blood pressure were greater during test sessions that included verbal ratings of pain, as compared to sessions in which pain was not reported. In contrast to its effect on physiological activation, reporting pain did not significantly alter the participant's perception of the painfulness of the lest, on recollection shortly after the test. We conclude, therefore, that reporting pain during the cold pressor test may impose significant additional demands on the cardiovascular system, but it does not interfere significantly with the processing of nociceptive information.

Effects on humans elicited by inhaling the fragrance of essential oils: sensory test, multi-channel thermometric study and forehead surface potential wave measurement on basil and peppermint.

The effects on humans inhaling the fragrance of essential oils were examined in terms of a sensory test, a multi-channel skin thermometer study and a portable forehead surface electroencephalographic (IBVA-EEG) measurement. The essential oils examined in this study were those of basil and peppermint, because our previous sensory test had indicated an opposite effect of these essential oils when mental work was undertaken; the inhalation of basil produced a more favorable impression after work than before work, whereas peppermint produced an unfavorable impression under these circumstances. For subjects administered basil or peppermint before and after mental work using an inhalator, a series of multi-channel skin thermometer studies and IBVA-EEG measurements were conducted. Using such paired odorants, our results showed that when compared between before and after mental work assigned to subjects: (1) the inhalation of basil, in which a favorable impression was predominant on the whole in terms of the sensory evaluation spectrum, was shown to be associated upward tendency in finger-tip skin temperature; (2) whereas these situations were opposite in the case of peppermint, in which the reversed (unfavorable) feature in sensory profiling was accompanied by a decrease in the magnitude of beta waves and a decrease in the finger-tip skin temperature both based on Welch's method, even at p < 0.01, implying a decreasing propensity of the aroused state and of the arousal response. The elucidation of such sensory and physiological endpoints of paired odorants would be of primary importance for human chemoreception science, because these are only rarely recorded during the same experiments, and this paradigm is highly informative about non-verbal responses to odorants.

Elicitation of spontaneous mirror reversal drawing on the forehead.

32 Japanese participants drew symmetrical and asymmetrical letters on their own foreheads. By observing their drawing strokes, it was judged that 29 of them drew symmetric letters in reverse, that is, as if these were viewed from inside the head. However, 14 of these 29 seemed to have noticed their reversed perception because they drew asymmetric letters intentionally reversed so they would appear correct when viewed from outside. Only three participants drew the letters in a normal way irrespective of the letter symmetry.

Large Indian forehead rhinoplasty. Case report.

The classic Indian rhinoplasty, with a midline forehead flap, was performed on 4 young adult patients with "cut noses". The rather large flaps survived in all cases, without a delay procedure, and the results were surprisingly good. The appearance of the donor area is, however, a problem-especially in patients with pigmented skins. The method is relatively simple and we believe it to be of value in selected cases.

[One-stage nose reconstruction using a forehead island flap].

Only part of the nasal skeleton remains after resection of extensive tumours penetrating all layers of the nose. In most cases a multiple-stage procedure is necessary for reconstruction of subtotal and total nasal defects. However, a one-stage reconstruction is needed in old and physically disabled patients who cannot undergo multiple operations for medical or social reasons. Three cases of nasal reconstruction with an inverted forehead island flap are reported. The skin of the inferiorly transposed flap serves as an inner lining for the reconstructed nose; the outer layer of the flap, which forms the surface of the reconstructed nose, is covered by a split thickness skin graft. The advantages of the method are: (1) one-stage reconstruction of the nose after tumour resection without further operations; and (2) the relative stability of the reconstructed nose without cartilaginous or bony implants.

Prefabricated microvascular shoulder free flap for forehead reconstruction.

In a case with a large forehead defect following tight scalp bandaging in childhood, a prefabricated microvascular shoulder free flap was used for reconstruction. A free forearm fascial flap, with the radial artery and the concomitant vein as pedicle, was harvested and inserted under a subcutaneous pocket opened in the left shoulder region which served as the future "prefabricated free flap". In addition, a tissue expander was placed in this pocket to provide the necessary tissue expansion to enable primary donor site closure.

[Occipital forehead pedicle for one-stage repair of defects of the upper third of the face].

The authors describe a reconstruction technique for defects of the superior third of the face using a fascio-cutaneous flap with a forehead paddle supplied by an occipital pedicle. This flap has been successfully used in three cases to cover defects of the temporo-zygomatic area indeed, the superior part of the cheek. Our three patients presented recurrent cutaneous carcinoma, a local and general poor condition. This process suits reliability and easiness to a good carcinologic, functional and aesthetic result.
