Zygomatic implantation and external elevation in the treatment of anatomic variation of maxillary sinus: a case report

doi:10.19438/j.cjoms.2023.06.015

Abstract

Abstract: Pneumatization of the maxillary sinus extending to the zygomatic bone is a rare anatomic abnormality. Zygomatic implants cannot be performed for patients with insufficient zygomatic bone quantity. In this paper, a case of congenital severe left maxillary sinus gasification was reported. The patient was treated with right (healthy side) zygomatic bone implantation combined with conventional implant in the maxillary anterior dental area for immediate repair, and left (affected side) external maxillary sinus lifting delayed implant repair and implantation for fixed implant repair, which achieved ideal therapeutic effect. This article discussed the possible etiology, differential diagnosis of the variant maxillary sinus, and the selection of implant treatment methods for patients with severe maxillary defects, aiming to provide an optimal implant fixation treatment for this type of patients.

Key words: Maxillary sinus pneumatization, Zygomatic implant, Sinus floor elevation with lateral window approach, Immediate repair
