Chronic Sinusitis Complicating Sinus Lift Surgery

TLDR

Sinusitis can arise after sinus lift surgery from mucoperiosteal flap tears, graft extrusion, and obstruction of sinus outflow by edema or particulate graft material. The study reviews the clinical presentation and management of 14 cases of chronic sinusitis following sinus lift with alloplastic hydroxyapatite augmentation. The procedure creates a submucoperiosteal pocket in the maxillary sinus floor to place a graft of autogenous, allogenic, or alloplastic material.

Abstract

Sinusitis has been reported as a complication of sinus lift surgery with antral bone augmentation. The procedure involves the creation of a submucoperiosteal pocket in the floor of the maxillary sinus for placement of a graft consisting of autogenous, allogenic, or alloplastic material. This can result in inadvertent tearing of the mucoperiosteal flap with extrusion of graft material into the antrum. Obstruction of the sinus outflow tract by mucosal edema and particulate graft material may result in sinusitis. We will discuss the clinical presentation and management of 14 cases of chronic sinusitis following sinus lift surgery with alloplastic hydroxyapatite (HA) augmentation of the maxillary antrum.
