Abstract：Objective This study aimed to evaluate the effect of a mandibular fixation guide for condyle fixation on mandibular reconstruction using fibular flaps.Methods This study included 10 patients (7 males and 3 females, aged 22-65 years), who were treated for mandibular resection and reconstruction using fibular flaps in Nanjing Stomatological Hospital from January 2017 to December 2018. Among the 10 patients, 4 were diagnosed with adamantoblastoma, 2 were diagnosed with primary intraosseous carcinoma of the mandible, and 4 were diagnosed with carcinoma of the lower gingiva. These patients used guide plates, including mandibular and fibula cutting, mandibular fixation, and titanium plate transfer guides, for the entire procedure. All the patients were followed up and evaluated for postoperative complications, temporomandibular joint (TMJ) space, and residual mandibular position.Results All surgical guides were applied successfully during surgery, and all fibular flaps survived. The duration of surgical operation was approximately (482.56±59.83) min. One patient complained of limited mouth opening by approximately 2.5 cm, but no other complication occurred. The shifted distance of the affected residual mandible was (-0.69±2.28) mm. No significant change was observed in the anterior, upper, and posterior spaces of the TMJ after surgery (all P values＞0.05).Conclusions A mandibular fixation guide reduced changes in the TMJ space and the shift of the residual mandible; thus, it benefits mandibular reconstruction using fibular flaps.
