Herniation of antral membrane through oro-antral fistula with polyp formation-a case report
Oroantral communication fistula is a common complication of dental extraction of posterior maxillary teeth. The occurrence of herniation of the antral membrane with large polyps extending through fistula into the oral cavity is rare. Here we report a case of herniation of an antral polyp through an oroantral fistula, appearing as a polypoid lesion in a female patient aged 24-year-old, who underwent an extraction of her upper molar two months ago. The soft tissue mass was asymptomatic, red in colour and nontender to palpation, involving the alveolar ridge in the maxillary molar area. Patient underwent surgical removal of the soft tissue mass followed by closure of the oroantral fistula.
