Abstract

One of the most commonly seen complications by oral and maxillofacial surgeons is Oro-antral communication or Oro-antral fistula. It is an unnatural connection formed between the oral cavity and the maxillary sinus [1]. Minor oroantral communications of smaller diameter i.e., 1 to 2 mm will eventually heal on its own after the formation of a blood clot and secondary healing but even after that formation of an oroantral fistula (OAF) becomes unavoidable as some of the major communications remain undiagnosed [2]. Due to the anatomic proximity or projection of the roots of upper pre-molars and molars within the maxillary sinus, extraction of these teeth usually results in formation of OAC (seen in 48% of cases). Patient diagnosed with OAC will give history of various unpleasant symptoms like a reduced sense of smell and taste, pain in maxillary teeth, postnasal exudate, and halitosis [1].
