Application of the interseptal alveolotomy for closing the oroantral fistula.
OBJECTIVE
This article describes a new application of the interseptal alveoplasty to close oroantral fistulae caused by dental extraction. The surgical technique is described, and its advantages are compared with those of other techniques.


METHODS
The technique was used to treat eight patients with comparatively small fistulae in the soft tissue, approximately 1 to 5 mm wide.


RESULTS
All fistulae were successfully closed.


CONCLUSIONS
It is proposed that the technique provides greater flexibility in the treatment of fistulae. In addition, because there is a bony base, this promotes more successful healing than other commonly used procedures.
