The prevalence of upper lip hair in black and white girls during puberty: a new standard.

In order to develop standards for upper lip hair in adolescent girls, 4693 observations in 856 black and white subjects were made over 9 years. Up to 2 years after menarche, 90% of girls had no upper lip hair. More than 2 years after menarche, 48.8% of black girls and 9.0% of white girls had small amounts of upper lip hair. This may be more significant in adolescent girls than in older women.

Hyperoxia and hypoxia in pregnancy: simple experimental manipulation alters the incidence of cleft lip and palate in CL/Fr mice.

This paper describes alterations in the incidence of cleft lip and palate in CL/Fr mice subsequent to experimental manipulation of maternal respiratory oxygen levels during a critical period of pregnancy. Only a few previous studies have shown that the incidence of some "genetically determined" malformations in mammals can be decreased by environmental procedures. In addition to demonstrating a decreased incidence of cleft lip and palate subsequent to maternal hyperoxia on gestational days 10 and 11 in a genetically susceptible strain, the results of the present study show that hypoxia at this time increases the incidence of cleft lip and palate.

Scanning electron microscopic study of the structures associated with lips of an Indian hill stream fish Garra lamta (Cyprinidae, Cypriniformes).

The surface architecture of the structures associated with the lips of a hill stream fish Garra lamta was examined by scanning electron microscopy. In this teleost, the lips are inconspicuous and associated with prominent horny jaw sheaths. Furthermore, the upper and lower lips are associated with a greatly enlarged rostral cap and an adhesive pad, respectively. The rostral cap has a proximal mucogenic region and a distal keratinized region. The adhesive pad is differentiated into central mucogenic and peripheral keratinized regions. At the mucogenic regions of the rostral cap and the adhesive pad, the surface of the epithelial cells is characterised by well developed microridges, which reflect their high secretory activity. The mucus may lubricate the surface and protect the epithelia from abrasions at these regions, which are likely to be subjected to wear and tear during frequent friction and adhesion of the fish to the substrate. Taste buds may help the fish to locate food and trigger a 'pick-up' reflex. The epithelial cells at the surface of the keratinized regions of the rostral cap and the adhesive pad are modified as clusters of spine like unculi, which may assist the fish in its firm anchorage to the substrate. The epithelial cells at the surface of the horny jaw sheaths are modified as polygonal unculi, each appears much like a tooth that has a characteristic sharp edge at the margin. These may be regarded as an adaptation to browsing or scraping food materials from the substrate.

Cytophotometrical and immunohistochemical analysis of soft palate muscles of children with isolated cleft palate and combined cleft lip and palate.

Palatal muscle biopsies from the cleft margin of children were subjected to cytophotometrical and immunohistochemical analysis. Muscle fiber types were classified according to the enzyme activity of myofibrillic adenosine triphosphatase, glycerol-3-phosphate-dehydrogenase and succinate dehydrogenase assessed cytophotometrically. Fiber type-related immunoreactivity of nitric oxide synthase (NOS) isoforms I, II, III, as a physiological modulator of skeletal muscle function, was related to the oxidative and glycolytic activity of the muscle fibers. Fast oxidative glycolytic fibers with high oxidative activity showed strong NOS I immunoreactivity, whereas fast glycolytic fibers with high glycolytic activity were stronger immunolabelled for NOS III. NOS II expression was similar in all fiber types. No differences in NOS immunoreactivity were found between the two investigated forms of deformity. Additionally to the usual skeletal muscle fiber types, a slow tonic fiber type was for the first time identified in cleft palate muscles. Comparison of two forms of cleft palate, isolated cleft palate and combined cleft lip and palate has shown decreased enzyme activities in muscle fibers of palatal muscles from combined cleft lip and palate. Fast oxidative glycolytic fibers were mainly effected. Cytophotometrical and immunohistochemical analysis indicated a depressed performance of the cleft palatal muscles from combined cleft lip and palate as a stronger deformity compared with isolated cleft palate.

The relationship between early speech and later speech and language performance for children with cleft lip and palate.

This study examined the relationship between speech measures at presurgery/9 months and postsurgery/13 months and speech and language performance at 21 months for children with cleft lip and palate and their noncleft peers. Comparisons were also made between the speech and lexical development of children with cleft lip and palate and noncleft children at 21 months of age. The participants included 30 children; 15 with cleft lip and palate and 15 noncleft children. Results revealed differences between the groups for several measures of speech and lexical development at 21 months. For the children with cleft palate, correlational analyses suggested that true stop production, both immediately before and after palatal surgery, was positively correlated with a majority of the speech production measures at 21 months. At postsurgery/13 months, true stop production was related to later vocabulary development, and size of true consonant inventory was related to all measure of speech production and one measure of lexical development at 21 months. For the noncleft group, true canonical babbling ratio at 13 months was the only measure that was significantly correlated with any of the speech and/or language measures at 21 months. The impact of clefting on prelinguistic and later speech and language skills is discussed.

Facial appearance in adults who had cleft lip and palate treated in childhood.

Sixty-eight adults (44 men and 24 women) with treated total cleft lip and palate were compared with a group of 66 adults (49 men and 17 women) without clefts, matched by sex and age. The outcome measures included a self-report questionnaire about body image, quality of life in general, health-related quality of life, somatisation, and depression. The group with clefts were also asked if they had further need of treatment. They reported significantly more dissatisfaction with their facial appearance (nose, lips, mouth, profile, and overall facial appearance) than the group without clefts. Satisfaction with facial appearance was significantly correlated with a better quality of life in both groups, and significantly correlated with a better health-related quality of life and a lower grade of somatisation in the group with clefts. Dissatisfaction with facial appearance was the most significant predictor of depression in both groups. A panel of four professionals from a cleft lip and palate treatment team judged the outcome of treatment in 64 of the subjects on colour slides. The professionals and the subjects with clefts were generally not very satisfied with the results of the surgical outcome. Thirty of the subjects with clefts (47%) wished to have more operations. The professional group recommended further operations in 38 of the cases (59%), in particular, rhinoplasties. We conclude that the subjects with treated clefts were not satisfied with their facial appearance, although they seem to be psychosocially well-adjusted to their disability.

One-stage correction of severe nasal deformity associated with a unilateral cleft lip.

Correction of one of the abnormal features is never enough to alleviate the entire deformity in a patient with a unilateral cleft lip and deformed nose, because the factors that led to the nasal deformity have already produced changes in the lower lateral cartilage, nostril, columella, septum, and alar base. These changes should be treated together with the contributory factors. By restoring the balance of the muscles by primary repair of the lip, orthodontic treatment, and orthognathic surgery, a more symmetric skeletal base can be established. The method of repair of the lip will also influence the deformity. Bone grafting can augment the skeletal base, but it will not improve the position of the lower lateral cartilage or the deviated septum. In this paper we describe a single stage correction of all the irregularities of the nose in patients with unilateral clefts which alleviates the asymmetrical nasal deformity.

Reconstruction of microform cleft lip.

Partial cleft of the orbicularis oris muscle without skin and mucosa can also be called "discontinuity of the orbicularis oris muscle" or "subepithelial cleft". Microform cleft lip or mini-cleft lip are better definitions. We present two women aged 25 and 29 years old who complained of vermilion notching, vertical depression on the upper lip, and asymmetry of lower lateral cartilage of the nose. The "discontinuity of the muscle" was found at operation in both cases and reconstructed successfully.

Clinical examination compared with morphometry of digital photographs for evaluation of repaired cleft lips.

Twenty-four adult patients who had been operated on as infants for isolated cleft lip underwent clinical examination combined with photographic documentation using a digital camera. The same predetermined protocol comprising 20 variables describing nasolabial appearance was used for both the clinical examination and the computerised evaluation of the images. The correlation between the two methods is described in the present study. The results obtained with the two methods agreed closely. For metric variables the mean coefficient of correlation was 0.73 and when all measurements were combined, it reached 0.98. Likewise, discrete variables showed a close correlation, with a mean kappa value of 0.72. Variables related to muscular dynamics of the lip can for obvious reasons not be judged from photographs. However, the computerised photographic evaluation was able to detect more precisely even minor angular deviations of the nose and to measure areas such as the areas of the nostrils. We conclude that morphometry of digital photographs is a new valuable clinical tool for the assessment of the nasolabial appearance in patients with cleft lip and palate.

Bilateral infraorbital nerve block is superior to peri-incisional infiltration for analgesia after repair of cleft lip.

Cleft lip repair is a common operation in infants and requires that the child is pain-free during the postoperative period so that handling does not affect the integrity of the delicate surgical site. This study was designed to compare the efficacy and duration of effect of 0.125% bupivacaine given preoperatively as a bilateral infraorbital nerve block with peri-incisional infiltration of the same local anaesthetic for postoperative analgesia in cleft lip repair. It was a randomised, double blind, prospective study in 30 children aged 4-20 months (ASA grade 1). After a standard induction, group A (n = 15) were given a bilateral infraorbital nerve block with 0.125% bupivacaine and group B (n = 15) had peri-incisional infiltration with the same solution. No additional systemic analgesics were given before or during the operation. Intraoperative monitoring comprised measurement of heart rate and blood pressure and post-operatively pain relief was recorded using a behavioural pain relief score. The heart rate, respiratory rate, and blood pressure were also monitored at 0, 1, 2, 4, 8, and 24 hours after tracheal extubation. The results showed that group A had significantly better pain relief (higher scores) than group B for eight hours postoperatively (p < 0.05). The analgesic requirement in group B became significant at two hours postoperatively, while group A had significant analgesic requirements only after eight hours. The significant rise in heart rate and blood pressure that accompanied tracheal intubation in both groups suggested that while both methods of analgesia may be adequate to prevent responses to skin incision, they do not substitute for adequate systemic analgesia during the operation. We conclude that infraorbital nerve block with 0.125% bupivacaine provides better and more prolonged analgesia than peri-incisional infiltration in cleft lip repair.

Are isolated facial cleft lip and palate associated with increased perinatal mortality? A cohort study from the West Midlands Region, 1995-1997.

OBJECTIVE: To investigate the association between cleft lip and/or palate and perinatal mortality. METHODS: A retrospective review was performed of cases of cleft lip/palate born to West Midlands residents from 1995 to 1997. Perinatal mortality for identified cases was compared with all births from 1995 to 1997. RESULTS: 347 cases of cleft lip and/or cleft palate were delivered from 1995 to 1997. Thirty-six pregnancies were terminated due to parental wishes--2 were registerable births. There were 310 spontaneous registerable births (stillbirths/livebirths) with cleft lip and/or palate and 1 further late fetal loss. In 220 (70.5%), the lesion was isolated. Of these, there were 7 perinatal deaths, 5 had post mortems and no additional anomalies were identified. In 92 (29.5%) cases other abnormalities were identified. The overall perinatal mortality rate (PNMR) in the West Midlands, was 10.0/1000 total births. The overall PNMR for babies with facial clefts was 89.7/1000 total births. The PNMR for those with associated anomalies was 228.3/1000 live/still births. The PNMR for isolated facial clefts was 31.8/1000 live/still births, significantly higher than the background population (OR 3.3, 95% CI: 1.5-7.0). CONCLUSION: Consideration should be given to screening the fetus at 20-24 weeks for facial deformity. This has implications for detection both of fetal anomalies and of a population at risk for adverse outcome.

Difficult laryngoscopy in cleft lip and palate surgery.

We studied prospectively 800 paediatric patients undergoing repair of cleft lip and palate to determine the predictors of difficult laryngoscopy. The incidence of difficult laryngoscopy (Cormack and Lehane grade III and IV) was 2.95% in patients with unilateral cleft lip, 45.76% in bilateral cleft lip and 34.61% in patients with retrognathia. Tracheal intubation was successful in 99% of patients in whom laryngoscopy was difficult. There was a significant association between age and laryngoscopic view (P < 0.01).

Regional guideline for diagnosis and treatment of squamous cell carcinoma of the lip: what is the level of compliance?

OBJECTIVE: To investigate to what extent physicians comply with a regional guideline for the diagnosis, staging, treatment and follow-up of patients with squamous cell carcinoma of the lower lip. DESIGN: Retrospective analysis of data from the medical records of 248 patients diagnosed with squamous cell carcinoma of the lower lip during the period 1989-1997. SETTING: Comprehensive Cancer Centre of the Northern region of the Netherlands. STUDY PARTICIPANTS: The data were collected by this Centre for the regional population-based cancer registry. RESULTS: Overall compliance with the separate guidelines varied between 4 and 80%. For diagnosis and staging, the guideline was followed for 4-70% of patients. The type of treatment in relation to age conformed to the guideline in 34% of cases. Of the 208 surgically-treated patients, treatment was performed in accordance with the guidelines in 92 (44%) patients, compared with seven out of 18 (39%) patients who received radiotherapy. Follow-up in accordance with the guideline was 11% in the first year, 9% in the second year and 21% in the third year. CONCLUSION: Only a minority of patients with squamous cell carcinoma of the lower lip, a rare rumour, were managed according to the available regional guideline. Regular review of both the guideline and its implementation is necessary in order to optimize its use.

Pagetoid dyskeratosis of the lips.

Pagetoid dyskeratosis is an incidental finding in a variety of lesions of the skin and squamous mucosa. The lesion is considered a selective keratinocytic response in which a small part of the normal population of keratinocytes is induced to proliferate in response to friction. As far as we know, pagetoid dyskeratosis has not been reported in the lips. In this article, we describe the location of the lesion in the lips and its incidence in a group of 90 unselected patients who underwent biopsy or were surgically treated for diverse labial lesions. Histochemical staining and immunohistochemical studies were performed in selected cases. Pagetoid dyskeratosis was found in 38 cases (42.2%) but only in 6 cases (6.7%) the lesion was conspicuous. There was no significant difference between the upper and the lower lip in terms of incidence of the lesion. Labial pagetoid dyskeratosis was more frequent in younger patients (46.7 +/- 25.0 versus 58.5 +/- 20.5; p < 0.05) and in women (chi(2) = 3.89; p < 0.05). Pagetoid cells were more common in suprabasal location and in the labial mucosa. These cells showed positivity for high-molecular weight cytokeratin and negative reaction for low-molecular weight cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, and human papilloma virus. The immunohistochemical profile is different from the surrounding keratinocytes, indicating premature keratinization. The main differential diagnoses include white sponge nevus, leukoedema, oral koilocytoses, hairy leukoplakia, pagetoid squamous cell carcinoma in situ, and extramammary Paget's disease of the oral mucosa. The morphologic features of dyskeratotic pagetoid cells are distinctive and easily recognized as an incidental finding, thus preventing confusion with other important entities including an intraepidermal tumor.

Carboplatin plus ftorafur as a palliative treatment in locally advanced cancer of the oral cavity and lip.

Forty consecutive patients with local advanced cancer of the oral cavity and lip, heavily pretreated, were palliated with two courses of carboplatin, 400 mg/m2 intravenously once a month plus ftorafur, 500 mg/m2 daily per os for 30 days. Previous treatment consisted of surgery (17 patients), radiation therapy (23 patients), and chemotherapy with cisplatin plus bleomycin (15 patients). The main sites of primary tumor were the tongue (12 patients), hard palate (6 patients), retromolar area (6 patients), tonsils (6 patients), perioral skin and lip (5 patients), and floor of the mouth (5 patients). Complete response was observed in 3 patients, and partial response in 7. Symptomatic improvement was observed in 56% of the cases. Median duration of response was 9 months. Median survival was 7 months. The main toxic effects were nausea (39 cases), vomiting (35 cases), and thrombocytopenia (4 cases). We conclude that carboplatin plus ftorafur has a role as palliative chemotherapy in cancer of the oral cavity and lip in heavily pretreated patients when local therapies are not suitable.

Muscle repair in unilateral cleft lip, based on findings on electrical stimulation.

The appearances, distribution, and direction of muscle in the unilateral cleft lip as indicated by electrical stimulation are described. The findings differ from those reported by Fara and associates in their dissections in that functionally the fibers do not appear to parallel the margin of the cleft. Based on these findings, a method of layer-by-layer, step-by-step closure of the unilateral cleft lip is described that attempts to split the orbicularis bulge and advance the lateral muscle into the philtrum to a position more nearly imitating the direction and extent of the muscle in a normal lip.

Secondary repair of the cleft-lip nose.

Secondary repair of the cleft-lip nose has to date concerned itself only with correction of the lip and external nasal deformity. However, intensive corrective surgery of the deformed nasal septum, which may cause functional and cosmetic handicaps, is also essential in reshaping the drooped nasal tip and alar wing. This paper presents the basic techniques for correcting the deformed nose and nasal floor including the oronasal fistula dn its supportive structures--deviated nasal septums, tilted columellas, and so on. Several patients are presented with cleft-lip nose deformities satisfactorily repaired using these techniques.

Reconstruction of the upper and lower lip using a modified Bernard-Burow technique.

Our experience with a modified Bernard-Burow technique for upper and lower lip reconstruction is described with preservation of the muscular lip sphincter. The use of local skin and buccal mucosal flaps sliding over the preserved muscular sphincter enables reconstruction with an acceptable cosmetic result even when almost total lip resection is required.
