The increased middle face height, with a short upper lip and visible upper alveolar process, is an indication for removing a slice of bone from the maxilla. Planning of the operation and operative procedures will be described. It is shown that osteosynthesis with miniplates without the need for intermaxillary fixation is possible, provided that the planning is painstaking and that a precise operative technique is used. 相似文献

OBJECTIVE: To review the clinical outcome for patients with Van der Woude syndrome undergoing surgical excision of congenital lip sinuses. DESIGN: Retrospective chart review. SETTING: Multidisciplinary cleft-craniofacial team within a tertiary care hospital. PATIENTS, PARTICIPANTS: Seventeen patients with Van der Woude syndrome were identified from hospital records as having cleft lip and/or palate surgery performed at the University of Iowa, and six of these patients underwent simple surgical excision of lower lip sinuses. Main OUTCOME MEASURES: Incidence of postoperative complications and number of surgeries required per patient for correction of lower lip defect. RESULTS: All six patients undergoing surgical excision of lip sinuses had postoperative mucocele formation. These uniformly required one or two further surgeries for correction. There were no other complications associated with the procedures and no patient had a pre- or postoperative whistling deformity. Cosmetic outcome was thought to be satisfactory in all cases. CONCLUSIONS: Despite the overall improvement in cosmetic appearance following simple surgical excision of congenital lower lip sinuses, the high rate of mucocele formation and repeat surgery has led to cautious preoperative counseling regarding the risks and benefits of the procedure. 相似文献

The presence of lower lip pits in individuals with Van der Woude syndrome (VWS) may cause discomfort due to saliva secretion. Furthermore, one of the main complaints in relation to lip pits is poor aesthetics, which often affects quality of life. The aim of this systematic review was to identify the best technique for the surgical removal of lower lip pits in terms of aesthetic and functional characteristics. A search of the PubMed, Embase, Web of Science, Science Direct, and Scopus databases was performed on December 27, 2016, which retrieved 88 records without duplicates. Among these papers, three ultimately met all eligibility criteria. The three studies included a total of 61 individuals, with follow-up ranging from 6 months to 10 years and sample collection from 10 to 24 years. The findings demonstrated that the outcome of surgical removal of lower lip pits was better with the use of vertical wedge excision, inverted-T lip reduction, Mutaf–Goldstein technique and modified simple excision than with simple excision. Simple excision may result in postoperative complications, such as mucocele and pit recurrence. 相似文献

The use of buccal mucosa and a tongue flap in reconstruction of full-thickness defects of the lower lip is described. The patient's face received a heavy blow in a traffic accident. Necrosis caused by hematogenous disturbance occurred in more than half of the entire lower lip vermilion. The patient underwent a two-stage operation for reconstruction of the lower lip. First, vestibuloplasty was performed using a buccal mucosal flap. Subsequently, the vermilion was surgically reconstructed using a flap from the tip of the tongue. This operative method is less risky because of its favorable prognosis. An effective way to recover motor function of the lower lip is to practice a rehabilitation program against scar contraction. An extension movement with the fingers that requires two or three repetitions every day was selected. Rehabilitation was started 7 days after the tongue flap was divided. The patient had a favorable recovery after the operation and is now able to wear a denture and to eat without slobbering. 相似文献

The decision is not always straightforward as to which orthognathic procedure is best for a good aesthetic result; three-dimensional imaging has brought new insight into this topic. The aim of this prospective study was to verify objectively whether postoperative changes occur within those regions not directly affected by surgical movements of the underlying jaw bones. The study included 83 young adults with skeletal class III deformities. They were classified into three groups according to the type of surgery: bilateral sagittal split osteotomy set-back of the mandible (BSSO), Le Fort I advancement of the maxilla, or a combination of both. Pre- and postoperative optical scans were registered as regional best-fits on the areas of the foreheads and both orbits. The shell to shell differences were measured and the average distances between the observed regions were calculated. As expected, changes were greatest in the regions where the underlying bones had been moved, but regardless of the operation performed, changes were found over the whole face. Changes in the nose, cheek, and upper lip regions in the BSSO group and in the lower lip and chin region in the Le Fort I group confirmed the concept of the facial soft tissue mask acting as one unit. 相似文献

Objectives: We are presenting our experience collected from a series of 109 cases with SCC of the lower lip focusing on clinical features of patients and surgical approach.
Study Design: We retrospectively analyzed medical records of patients diagnosed with Squamous Cell Carcinoma (SCC) of the lower lip at the Oral and Maxillofacial surgery at Xi’an Jiaotong University during a period between 1999 and 2008.
Results: A total of 109 patients with lip cancer were included in the study. When no frozen-section test was performed, the neoplasia was removed with a margin of at least 6 mm. Different surgical techniques were used for lip reconstruction after tumor excision. Neck dissection was performed in all patients with clinically palpable lymph nodes. Median follow-up was 38 months. During follow-up, recurrence occurred in 5 patients, 3 patients developed neck metastases, distant metastases developed in 1 patient. Five patients died during observation period.
Conclusions: The patient-related and defect-related issues must be taken into consideration during reconstruction for surgical defect. For N0 patients, we recommend wait-and-see policy. Early detection, careful follow-up and prompt neck is essential for the successful treatment.
Key words:Lip cancer, surgical management, reconstruction. 相似文献

OBJECTIVE: To assess the skeletal and dental craniofacial proportions of unilateral cleft lip and palate patients who were operated upon using the Malek technique, and compare them with a normal group to highlight the effect of surgical correction on craniofacial development during growth. DESIGN: Retrospective. METHODS: The cleft palate was closed using the Malek technique in a single operation at 3 months for 11 patients (complete closure of lip and palate) and in a two-stage operation for 10 patients (soft palate at 3 months, lip and hard palate at 6 months). Comparisons were made with a normal control group. Angular and linear measurements of anterior and posterior dimensions of the upper and lower compartments of the face were measured in the 7th and 12th years. RESULTS AND CONCLUSION: No significant differences were observed between the two groups of palate technique repair, although significant differences were observed between craniofacial dimensions of normal versus cleft lip and palate patients. At a skeletal level, the maxilla and mandible were retrusive relative to the cranial base in the cleft lip and palate group. In fact, there was a backward rotation of the palatal plane with repercussions on the maxillo-mandibular complex position. Furthermore, the maxilla was shorter than in normal patients, whereas the mandible was normally shaped. The upper incisors were retroclined and they locked the lower incisors in linguoversion. There was a posterior skeletal deficit of the respiratory compartment, compensated by more marked posterior maxillary alveolar growth. Facial growth in cleft lip and palate patients followed the same pattern, but was delayed compared with normal patients. 相似文献

Frozen section examination of the margins for resection of squamous cell carcinoma of the lower lip. 总被引:3,自引:0,他引:3

OBJECTIVES: Our goal was to evaluate the role of frozen section margin examination in the surgical management of squamous cell carcinoma of the lower lip. MATERIALS AND METHODS: We reviewed frozen section examination of the resection surfaces of 131 consecutive patients surgically treated for squamous cell carcinoma of the lower lip during the period January 1980 to January 1999. When invasive carcinoma or carcinoma in situ was present at the resection surface, the margin was defined as positive and re-resection was performed. RESULTS: A peroperative positive margin was seen in 18 of 131 (14%). In 8 patients (6%), a local recurrence developed. CONCLUSIONS: Frozen section examination for margin assessment in the surgical treatment of lip cancer is a reliable technique to control the radicality of the procedure; a secondary surgical procedure or postoperative radiotherapy can be reduced. However, a tumor-free resection surface does not guarantee that local recurrence will not occur. 相似文献
