ABSTRACT
Introduction: comminuted mandibular fractures present significant challenges characterized by multiple bone fragments and high risks of necrosis, infection, and pseudoarthrosis. Conventional open reduction involves substantial surgical intervention that may compromise periosteal vascularization. Case presentation: we report the case of a 53‑year‑old male with a comminuted fracture of the mandibular angle and ramus treated with conservative management using intermaxillary fixation (IMF), Erich arch bars, and adjunctive botulinum toxin application. Monthly clinical evaluations and computed tomography (CT) imaging were performed. IMF was maintained for four months. Monthly clinical follow‑up showed functional stability without signs of infection. Post‑treatment CT demonstrated bone consolidation and fragment realignment. Intermittent anesthesia of the left mental nerve persisted, without other residual deficits. IMF was removed at four months, and the patient was discharged after an additional month of follow‑up. Conclusion: this case demonstrates that conservative management can achieve satisfactory consolidation in selected patients with comminuted mandibular fractures, preserving vascular supply and avoiding morbidity associated with open surgery. Given the paucity of comparable cases in the literature, this report contributes valuable clinical evidence to therapeutic decision‑making.REFERENCES
