Inverted papilloma of the maxillary sinus: an unusual cause of a non-healing extraction socket. Case report.

Although the healing of extraction sites is generally a rapid and uncomplicated process, delayed healing or overt infection of recent extraction sockets may involve a variety of causes and the clinician must be aware pre-operatively of both local and systemic influences. Retarded or non-healing extraction sites always require investigation. This paper looks broadly at the subject of non-healing extraction sites and reports an unusual case involving an inverted papilloma of the maxillary antrum. To the authors' knowledge this is the first reported case of an antral papilloma causing delayed extraction wound healing.
