Background: Temporomandibular joint ankylosis is a disabling condition leading to severe restriction of mandibular movement. The optimal surgical strategy remains debated, particularly regarding the use of inter positional material. Case Presentation: We report the case of a 15-year-old adolescent presenting with progressive complete bony Temporomandibular joint ankylosis following a history of complicated acute otitis media associated with facial cellulitis. Surgical management consisted of ankylotic block resection combined with ipsilateral coronoidectomy through a preauricular approach without inter positional graft. Results: Immediate intraoperative mouth opening improved from 0 cm to approximately 3 cm. A surgical gap estimated at 2 cm was achieved without residual bony contact. Early postoperative evolution was favorable with initiation of physiotherapy. Conclusion: Simplified gap arthroplasty without interposition may represent an effective surgical option in selected cases when adequate resection and early rehabilitation are ensured.
