Objective To evaluate the clinical outcome of the buccal fat pad flap in reconstruction of defects of the oral mucosa. Methods From May 1998 to July 2004, 42 patients with oral mucodefects were treated with buccal fat pad flap. Of them, there were 26 males and 16 females, aging 25-76 years. The defect was caused by buccal squamous carcinoma in 7 cases, by buccal leukoplakia in 5 cases, by squamous carcinoma of soft palate in 7 cases, by adenoid cystic carcinoma of palate in 8 cases, by carcinoma of maxillary sinus in 6 cases, by maxillo-alveolar angioma in 5 cases and by keratocyst of maxilla in 4 cases. The locations were buccal mucosa, maxillary sinus and soft palate. The size of defect ranged from 3.0 cm×3.0 cm to 6.5 cm×4.0cm.Results Forty-one cases achieved healing by first intention, except one case because of large defect. Edema faded and epithelization occurred after 4 weeks of operation. Complete epithelization was observed after 6 weeks of operation. Thirty-five cases were followed up 3 months to 5 years. Therewere no obvious differences in layers, color, elasticity, and texture between repaired region and adjacent mucosa. Conclusion The buccal fat pad flap is useful in reconstructing the muco-defects (less than 6.5 cm in diameter) of the posterior maxilla and buccal region without considerable complication. The multiplex blood supply, facility in accessing and minimal donor site morbidity make it a reliable soft tissue graft. The main shortcoming is its limited size.
Objective To discuss the reconstruction of severe neck contracture by transplanting combined scapular/parascapular bilobar flaps, and the probability to reestablish three-dimensional movement of the neck. Methods From January 2003 to November 2004, 9 cases of sustained severeneck contractures were treated (aged 9-32 years). The combined scapular/parascapular bilobar flaps, pedicled on the circumflex scapular vascular bundle, were microsurgically used to cover the soft tissue defect after excision of hypertrophic scar and release of contracture. The maximum size of the combined bilobar flap was 20 cm×8 cm to 20 cm×11 cm，while the minimum one was 15 cm×4 cm to 15 cm×6 cm. Results The combined scapular/parascapular flapswere successfully used to treat 9 cases of severe neck contracture. All patients were satisfied with the final functional and aesthetic results. There was no recurrence during 3-9 months follow-up for 8 patients. The cervicomental angle was 90-105°.Conclusion The combined bilobar scapular/parscapular flap, providing a large area of tissue for coverage in three dimensions with a reliable blood supply by only one pedicle anastomosis during operation, is agood option for reconstruction of the severe neck contracture.
