Surgical Management of Infection Secondary to Cemento-osseous Dysplasia

Abstract

Cemento-osseous dysplasia (COD) of the jaws generally has no clinical manifestations when asymptomatic, thus requiring no treatment. However, secondary infection in COD requires surgical intervention. This study was focused on the evaluation of the surgical treatment of COD patients with secondary infections. The clinical data of COD patients with secondary infections, treated at the Peking University, Hospital of Stomatology between March 2021 and June 2022, were retrospectively reviewed. The data included age, sex, lesion characteristics, number of surgeries, and surgical outcomes. Seven COD patients with secondary infections underwent curettage, and the wounds were repaired using local soft tissue flaps, such as the buccal fat pad. Four of the patients had primary wound healing, while 3 presented with wound dehiscence. Healing occurred in 2 of these 3 patients after ~1 month of dressings. The remaining patient showed no improvement after 9 weeks, and underwent a second surgery, which led to primary wound healing. In conclusion, secondary infection in COD is an indication for surgical intervention, which may arrest the disease progression.
