title: Pneumosinus dilatans of the maxillary sinus: a report of two cases.
abstract: Two cases of the rare condition of pneumosinus dilatans of the maxillary sinus are presented. This is a rare differential diagnosis of a maxillary mass. The precise aetiology and pathogenesis is obscure. Because facial deformity may persist after construction of a naso-antral window alone, direct resection and reconstruction using bone grafts is recommended in addition to the creation of a naso-antral window, if required.
