title: [The adipose Bichat bolla flaps in repair of oroantral fistulas].
abstract: The Authors review Literature concerning surgical treatment of oro-antral fistulas. After a brief discussion concerning the anatomy of the Bichat bulla, the Authors present two clinical cases of oro-antral fistulas with purulent sinusitis. The lesions were repaired using an adipose flap of the Bichat bulla which was sandwiched between the mucous flap and the bony defect. The partial introduction of the adipose flap in to the maxillary sinus through the bony defect, enabled the osteomyelitis bony edges to revascularize and created a pathway and biological substratum for re-epithelialization of the maxillary sinus. Clinical and radiological follow-up 24 months after treatment revealed stable closure of the fistula and normal ventilation of the maxillary sinus. On the basis of these results and those reported in Literature, the Authors advise employment of this technique, particularly in extensive oro-antral fistulas which do recur with other techniques and which, furthermore are complicated by local infectious processes.
