Summary
Midline mandibular osteotomy can cause minor long-term functional issues like altered sensation and occlusion. While most patients experience mild sequelae, temporomandibular joint (TMJ) function may also be affected.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthognathic Surgery
- Head and Neck Surgery
Background:
- Midline mandibular osteotomy is a surgical procedure with established oncologic validity and known perioperative complications.
- Long-term functional outcomes following this procedure, particularly concerning sensation, temporomandibular joint (TMJ) function, occlusion, and cosmesis, are less well-documented.
Purpose of the Study:
- To evaluate the long-term functional sequelae of midline mandibular osteotomy.
- To assess postoperative sensory changes, TMJ function, occlusal status, and cosmetic outcomes in patients who underwent the procedure.
Main Methods:
- A cohort of 31 patients who had previously undergone midline mandibular osteotomy were retrospectively examined.
- Assessment included evaluation of postoperative sensation, temporomandibular joint (TMJ) function, occlusion, and overall cosmesis.
Main Results:
- The majority of patients (27/31) experienced some sequelae, though these were generally minor.
- Abnormal sensation was reported by 20/31 patients, altered occlusion by 24/31, and TMJ myofascial pain signs/symptoms by 15/31.
- Despite functional changes, the overall significance of these sequelae was considered relatively minor.
Conclusions:
- Patients should be informed about the potential for minor long-term functional problems after midline mandibular osteotomy.
- The study suggests that functional issues are typically not severe, offering reassurance to patients.
- Consideration of a prefabricated lingual splint is recommended for cases prioritizing exact occlusal restoration, if technically feasible.
