Multimodal Conservative Management of Wound Dehiscence After Bilateral Atrophic Mandibular Fracture Fixation: A Case Report

: Bilateral fractures of the atrophic mandible in elderly patients pose a clinical challenge, particularly in the presence of systemic comorbidities and impaired healing capacity. In the present case, an elderly patient developed early, extensive postoperative wound dehiscence after surgical reduction and fixation. Initial management included debridement, systemic and topical antimicrobials, serial cleaning, and dressing changes. Because the dehiscence persisted, antimicrobial photodynamic therapy (aPDT) and photobiomodulation therapy (PBMT) were incorporated into a multimodal conservative protocol that also included warmed saline irrigation and occlusive dressings. Progressive tissue repair was observed, with complete wound closure after 12 aPDT/PBMT sessions and no loss of fracture stability or need for additional surgery. Because several interventions were administered sequentially and in combination, and this is a single case, the independent contribution of aPDT or PBMT cannot be determined. This report supports the success of a multimodal conservative strategy in a carefully selected patient but does not establish the efficacy of any individual therapy.
