title: An unusual oronasal fistula induced by prolonged cocaine snort. Case report and literature review.
abstract: In the last 50 years cocaine usage has had a growing incidence worldwide. Chronic nasal abuse of this drug can cause extensive oromaxillofacial destructive process as oronasal perforation. To author's knowledge the only type of oronasal fistula in cocaine abusers that has been reported to date has been perforation of the hard palate; a case of oronasal fistulas involving another region of oral cavity, the anterior gingival sulcus, has been reported only once. In this article authors present the first case of oronasal fistula involving hard palate and the right supero-lateral vestible induced by prolonged cocaine snort described in literature, review about the better surgical management for this lesion and the relationship between chronic cocaine abuse and elevated serum levels of c-ANCA.
