Bony Lid Approach in Dentoalveolar Surgery: Report of 2 Cases

Conventional surgical approach for cyst enucleation is removal of buccal compact bone plate, which often results in remarkable bone loss and subsequent mucosal recession. This report presents one case of residual mandibular cyst enucleation and one case of apicoectomized mandibular molar, both treated with the bony lid approach. A window of buccal compact bone was precisely created using an electro-powered osteotome orientated beyond the limits of cyst, followed by removal of the bone segment. After the completion of the enucleation and apicoectomy, the bony lid was relocated on its original position. The main advantage of this method over conventional one is maintaining the buccal compact bone plate integrity and minimizing the dimensions of the remaining bone cavity.
