Purpose <p>To evaluate the role of physiotherapy in accelerating facial nerve recovery following surgical management of condylar fractures using the periangular approach.</p> Materials and methods <p>This retrospective study included 44 patients with condylar fractures, comprising 56 fracture sites, treated between 1st October 2023 and 30th September 2024. All patients underwent open reduction and internal fixation (ORIF) via the periangular approach. Facial nerve function was assessed using the House–Brackmann Facial Nerve Grading System at 24&#xa0;h, 1 week, 4 weeks, 12 weeks, and 6 months. Of the 56 sites, 24 developed postoperative facial nerve weakness and were divided into two groups: Group A (<i>n</i> = 12) received physiotherapy with medication, and Group B (<i>n</i> = 12) received medication alone.</p> Results <p>The marginal mandibular branch was most frequently affected, followed by the buccal branch. Patients in Group A demonstrated significantly faster recovery of nerve function within 12 weeks compared to Group B (<i>p</i> &lt; 0.05). No postoperative complications such as infection, plate fracture, or hypertrophic scarring were observed. At the 6-month follow-up, all patients achieved complete recovery of facial nerve function.</p> Conclusion <p>Physiotherapy significantly accelerates functional recovery of the facial nerve after condylar fracture surgery through the periangular approach. Its incorporation into routine postoperative care may shorten rehabilitation timelines, improve patient participation, and enhance clinical outcomes.</p>
