[The study of maxillary protraction face mask combined with orthodontics for complete unilateral cleft lip and palate patients].

PURPOSE: The purpose of this study was to evaluate the influence of maxillary protraction face mask combined with orthodontics on complete unilateral cleft lip and palate patients' jaws. METHODS: 14 patients with complete unilateral cleft of lip and palate were included. Lateral cephalometric films were taken before orthodontic treatment ,before protracting and after orthodontic treatment. The statistical data were compared and analysed by SPSS10.0. Student's t test was used to determine the effect of maxillary protraction face mask combined with orthodontic treatment on jaw growth before and after treatment. RESULTS: The treatment resulted in good outcomes: incisor's overjet of 2mm, stable occlusion and straight profile. The SNA angle had a significant increase (P<0.001). The SNB angle and mandibular plane angle (SN-MP) have no change (P>0.05). The convexity of angle had significant change (P<0.001). CONCLUSION: Orthopedic force combined orthodontic treatment on patients with UCLP can promote the development of maxilla, without significant effect on the mandible. The overjet and overbite were improved by increasing the clination of upper anterior teeth, compensating lingually on lower anterior teeth and moving the upper anterior forward. The profile was improved from concave to straight, maxillary protrusion was increased, upper lip was plumpand, and the relationship between upper and lower jaws was more compatible.

[Philtrum formation in congenital cleft of upper lip].

Philtrum (labial groove) has aesthetic importance and governs individual features of human face. There are discussed the ways of philtrum reconstruction described in domestic and foreign literature. The main principles of the upper lip central part formation in one-sided congenital clefts are set out. Method of orbicularis oris muscle myoplasty by putting in the asymmetric stitches on deep and surface layers lets to reconstruct the philtrum and its column on the cleft side. Such philtrum reconstruction was performed in 90 cases of primary and secondary cheiloplasty in female patients with congenital one-sided clefts of the upper lips. Long-term results of 58 primary and 14 correcting operations on the upper lips were followed in the time period from 1 to 5 years. Good aesthetic results were achieved in 86.21 and 92.86% of the cases, respectively.

[A case report of a true median cleft of the upper lip with a pedunculated median skin-mucosa mass].

The Authors report an unusual case of median cleft of the upper lip with pedunculated skin and muscle contracting mass. About one hundred cases of true median cleft lip have been reported, only six showing a median pedunculated mass. As the embryogenesis of this malformation is still not completely clear, we think that any case with this characteristic has to be described. Besides the usual characteristic of the median "hare lip" this case shows a big egg-like pedunculated mass in which muscular tissue has been found well represented, and a wide incomplete maxillary cleft.

[Various aspects of the surgical therapy of cancer of the lower lip].

A safety distance of 1 cm from the excision margin as well as, frequently, removal of the regional cervical lymph nodes are usually recommended to ensure radical excision of carcinomas of the lower lip. Investigations on 32 such carcinomas revealed that a safety distance of 3-5 mm is sufficient, if the edge of the excised tissue is histologically controlled. 109 carcinomas of the lower lip were re-examined in order to settle the question of prophylactic dissection of the lymph nodes. The low metastasis rate of 1.8% suggests that prophylactic dissection of the lymph nodes is not necessary in these patients. However, 95% of all tumors classified as T1 according to the current T-classification by the IUAC for carcinomas of the lower lip occurred in this group of patients.

The lips: anatomy and differential diagnosis.

The lips are composed of striated muscle and connective tissue and are anatomically positioned to be maximally exposed to sunlight, environment, food, and tobacco. A number of topics relevant to the lips are presented, including contact dermatitis, contact urticaria, benign and malignant systemic processes, and the effect of systemically administered pharmacologic agents on the lips.

Arteriovenous malformations and vascular anatomy of the upper lip and soft palate.

Arteriovenous malformations (AVM) are a difficult clinical problem. These lesions may be extensive and diffuse and frequently prove refractory to the usual surgical methods of treatment. This paper presents three unusual AVMs of the orofacial region. Two were acquired AVMs of the upper lip, one involving columella; the third was a congential AVM of the soft palate. Complete surgical excision, following embolization, is the most successful therapy of traumatic AVM of the upper lip at this time. In addition, the blood supply of the upper lip and columella is presented, as it was found in ten cadaver dissections.

Radical muscle mobilisation in surgery for a unilateral cleft lip.

The embryological basis of a unilateral cleft lip is briefly outlined. The abnormal configuration of the orbicularis oris in a unilateral cleft lip is viewed on a model. The effect of freeing this muscle from its abnormal attachments and radically mobilising it, is theoretically discussed. The actual effects of such a mobilisation in clinical practice are shown. Post operative results of 16 unilateral cleft lips treated by radical muscle mobilisation are presented and discussed. The need for a longer follow up is recognised.

[Reconstruction of the lower lip].

The author describes techniques for the reconstruction of the lower lip, especially the wedge-shaped excision, the methods developed by Dieffenbach, Langenbeck, Estlander, Gillies, Weerda, Bernard and Grimm. Using the double Gillies fan flap, labial vessels are preserved because of the lack of circulary anastomoses in 75% and lack of anastomoses in the middle line of the upper lip in 60% and of the lower lip in 32% of the cases. Several examples are given.

Late correction of orbicularis discontinuity in bilateral cleft lip deformity.

The absence of muscle in the prolabial segment and the failure to identify and join the fibers of the orbicularis muscle from the lateral lip segments at the time of initial lip repair frequently result in a characteristic bulge above the vermilion laterally. This bulge is caused by the bunching of the orbicularis oris as the result of its discontinuity in the prolabial segment. Late repair of this deformity is possible. In a series of fifteen patients with previously repaired bilateral cleft lips, lateral mobilization and midline suturing of the separated segments of the orbicularis oris muscle have been employed to correct the orbicularis bulge. Significant improvement in oral animation and in facial aesthetics have been noted in these patients.

Primary lengthening of the columella in bilateral clefts of the lip.

Children with bilateral complete cleft lip and palate were treated by a two stage repair of the lip and nasal floor, including a small prolabial flap to lengthen the columella according to the technique of Skoog. Seventeen of these children, now at least 2 years of age were reviewed. In no case was normal length of the columella obtained, six children had obvious scars, in five the flap bulged at the base of the columella, and in four there was a displacement of the flap toward the lip. Three cases have already required a secondary forked flap. We concluded that the results of this procedure are inconsistent and od not justify the additional scarring.

Unilateral cleft lip repair. Z-plasty.

All unilateral clefts of the lip are not alike. The deficiencies that exist, especially in the lateral lip element, can vary considerably. Because of these differences, it is unreasonable to expect one technique of repair to satisfy all situations. In more difficult complete unilateral cleft lip deformity, the Z-plasty repairs described in this article better satisfy the goals of this surgery.

Orthognathic surgery in the cleft lip and palate patient.

Orthognathic surgery for the cleft lip and palate patient should be designed to achieve good facial aesthetics and a stable, functional occlusion. Maxillary and mandibular osteotomies, which benefit cleft lip and palate patients with associated dentofacial deformities, should be modified to meet the needs of the individual patient. Soft-tissue correction of the upper lip and nose adds to the overall aesthetic result, but should be performed as a separate procedure.

Deviations in craniofacial morphology in patients with complete unilateral cleft lip and palate evaluated by Jarabak's analysis.

The study is based on evaluation of X-ray films of the head of 29 boys aged 5 years and 34 males aged about 20 years with complete unilateral cleft of the lip and palate. Deviations in the craniofacial morphology were assessed using the Jarabak's analysis. Most linear dimensions were smaller in both children and adult patients. The exception was the posterior part of the cranial base the length of which was the same as in controls. The anterior part of the cranial base and the mandibular body were significantly shortened only in 5-year-old individuals while the maxillary body was shortened only in adult patients. The anterior facial height was elongated in adult patients. The mandible showed a posterior rotation, the gonial angle was increased in its lower part. The maxilla and mandible were retrusive with impaired vertical--and in adults also sagittal--jaw relations. Both upper and lower incisors showed retroinclination. In 5-year-old patients an anterior crossbite developed, a trend to open bite was evident in adult patients. The upper lip was retrusive while the lower lip was protrusive. Jarabak's method is not sufficient for an accurate analysis of the soft profile in patients with clefts.

[The new potentials for reconstructive restoration in defects of the lower lip after cancer operations].

Eleven patients with cancer of the lower lip were treated in 1995-1996. The first stage of treatment consisted of radiotherapy, the second one of resection of the lower lip with replacement of the defects with a dermatocutaneomucous flap from the cheek, including all anatomical components and hence permitting anatomically full-value repair of the lower lip. The method is reliable and effective.

[Age-related indications for cheiloplasty in congenital and acquired defects of the upper lip--an anthropological study].

Age-related changes in width (cheilion-cheilion) and height (subnasale-stomion) of the upper lip are studied in 2300 healthy Bulgarians, with ages ranging from three days to 102 years, for the needs of cheiloplasty in both surgery and fine arts. As shown by the results, at birth the upper lip in either gender appears to be one of the most developed organs of the human body, continuing to augment in size up to the eighth decade of life. In preschool age it terminates its intensive development, and in the puberty period it fails to exhibit the growth leap characteristic of the organism as a whole. Throughout the period of postnatal ontogeny, with the exception of early infancy, the lip in the male gender remains bigger, with the difference for height being rather markedly expressed during the ninth decade (3, 8 mm), and for width--thereafter (5.24 mm). The conclusion is reached that cheiloplasty may be undertaken regardless of the patient's age, during the early postnatal days inclusive, and the dimensions recorded for the age intervals being examined may serve as standard values.

Secondary rhinoplasty in nasal deformity associated with the unilateral cleft lip.

The secondary nasal deformity of the unilateral cleft lip involves a retrodisplaced dome of the ipsilateral nasal tip, hooding of the alar rim, a secondary alar-columellar web, and other deficiencies. The sliding-flap cheilorhinoplasty effectively corrects these deformities using a laterally based chondrocutaneous flap. We modified this technique by using an open rhinoplasty approach with the laterally based chondrocutaneous sliding flap. Columellar struts and shield grafts were some of the techniques combined with this approach to produce optimal results. In a total of 7 patients, we performed both the original sliding-flap cheilorhinoplasty and the modified open rhinoplasty, which are described and discussed herein. The laterally based sliding-flap cheilorhinoplasty is an effective technique for correcting both the secondary nasal deformity and the lip scar associated with the unilateral cleft lip.

Rhinologic computed tomographic evaluation in patients with cleft lip and palate.

OBJECTIVE: To investigate the anatomical characteristics of the nasal cavity and paranasal sinuses in relation to the presence of sinusitis in patients with cleft lip and palate. DESIGN: Retrospective survey. SETTING: Tertiary care hospital. PATIENTS: Forty-seven consecutive patients with cleft lip and alveolus with or without cleft palate. MAIN OUTCOME MEASURES: The patients underwent computed tomographic scans of the maxilla, and the following parameters were evaluated: nasal septal shift from the midline, soft tissue density shadow of the maxillary sinus, cross-sectional area of the maxillary sinus, and height of the floor of the maxillary sinus. RESULTS: The nasal septum was convex to the cleft side in most of the patients with unilateral clefts, and there was a significant correlation between the cleft side and the direction of nasal septal deviation (P<.001). Sinusitis was more severe in the noncleft side than in the cleft side (P =.04), and in the concave side than in the convex side (P= .02). The cross-sectional area of the maxillary sinus was not statistically different between the cleft side and noncleft side, nor between the septal concave side and convex side. The floor of the maxillary sinus was situated higher in the cleft side than in the noncleft side (P = .02). CONCLUSIONS: The occurrence of maxillary sinusitis associated with cleft lip and palate is dependent on both the cleft side and the deviated nasal septum, but not on the size of the sinus. The cleft side is responsible for the direction of the septal deviation and the height of the floor of the maxillary sinus. A low-situated sinus floor may be in contact with the root of the teeth, and thus may be one of the etiologic factors of sinusitis in patients with clefts.
