摘要

Background

Odontogenic maxillary sinusitis (OMS) can develop from apical periodontitis (AP) of maxillary posterior teeth, known as maxillary sinusitis of endodontic origin(MSEO). The treatment of OMS remains controversial. Endodontic microsurgery (EMS) plays a crucial role for treatment of AP when root canal treatment and retreatment fails. With multidisciplinary management, EMS alnoe may be effective for MSEO .

Case presentation

Ten cases of MSEO undergoing EMS are reported at the First Affiliated Hospital of Wenzhou Medical University between 2022 and 2023. Clinical and radio-graphic evaluations at 24-month follow-ups demonstrated periapical healing in all cases.

Conclusions

With multidisciplinary management, dental treatment alone may be a feasible approach for OMS(MSEO).
