Access to the maxillary sinus using a bone flap on a mucosal pedicle: preliminary report.

INTRODUCTION An alternative procedure to access the maxillary sinus is described. OBJECTIVE To describe advantages and disadvantages of the suggested technique of harvesting a bone flap based on an antral mucosal pedicle. MATERIAL Four patients have been operated on to remove foreign bodies or odontogenic cysts. RESULTS In all four patients, removal of the lesions and foreign bodies was easily accomplished. CONCLUSION The procedure described respects the morpho-functional integrity of the sinus, is easy, quick and may be performed under local anaesthesia.
