The incidence of lingual nerve injury in study group, where both lingual and buccal flap
were raised) is 12.5% whereas in control group (only buccal flap
raised) the incidence of lingual nerve injury is 6.25%.
Periosteal releasing incisions allowed a coronal displacement of the buccal flap
enough to close the wound, using mattress and tension-free simple interrupted resorbable sutures (3/0 VicrylA)
With a gingivobuccal incision, a buccal flap
was elevated and the anterior wall of the maxillary sinus was exposed.
The Roman, Aulus Cornelius Celsus, first described the use of bilateral buccal flap
, made between horizontal parallel incisions with the pedicle based laterally, for upper lip reconstruction in the first century AD.
A full-thickness buccal flap
was reflected and tied back to the vestibule using 2-0 silk suture material.
Oroantral communications described in the literature were secondary to extractions, excisions of cysts and tumors, sinus lifts ,periimplants.2,6 Methods of closure include buccal flap
advancement, palatal flap advancement , Combined buccal and palatal technique, distant flaps, bone grafts and alloplastic materials.
