Abstract
Objectives: This study aimed to explore the effect of surgery combined with bone perforation for treating stage Ⅱ medication-related osteonecrosis of the jaw (MRONJ).
Methods: A total of 21 patients with stage Ⅱ mandibular MRONJ who underwent surgical treatment from June 2020 to June 2023 were included in this study. Retrospective analysis was conducted on their clinical data, including gender, age, primary disease, drug name and administration method, pre-surgery drug cessation, and prognosis. The cohort comprised 14 males and 7 females, with an average age at onset of 68.33±10.74 years. According to the guidelines of the American Association of Oral and Maxillofacial Surgeons, the included patients had stage Ⅱ mandibular MRONJ. The treatment approach consisted of partial mandibulectomy combined with bone perforation techniques, ensuring tension-free suturing of soft tissues. Follow-up was performed regularly, and the curative effect was evaluated. The SF-12 health survey was used to assess the quality of life for all patients before and after surgery.
Results: A total of 21 patients were followed up for 8-38 months after surgery, and the mucosal healing of 17 patients was good (80.95%). The postoperative quality of life score (83.62±5.90) was significantly higher than that before operation (63.67±4.70, P<0.05).
Conclusions: Surgery combined with bone perforation te-chnique is an effective treatment method with high success rate in refractory stage Ⅱ MRONT patients.
