The Effect of Mandibular Medial Osteotomy Modifications on Postoperative Stability Following Orthognathic Surgery
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This study aims to compare the effects of the Hunsuck and Posnick modifications of medial mandibular osteotomy on postoperative skeletal stability and relapse in patients undergoing orthognathic surgery. The study will evaluate whether the choice of medial osteotomy technique influences postoperative mandibular relapse.

Treatments
Experimental: Hunsuck Modification Group
Patients undergoing orthognathic surgery with bilateral sagittal split ramus osteotomy (BSSO) will undergo medial mandibular osteotomy using the Hunsuck modification. The osteotomy will be performed according to the Hunsuck technique, with the medial horizontal osteotomy terminating at the level of the lingula and extending posteriorly to facilitate the sagittal split. Postoperative skeletal stability and relapse will be evaluated during the follow-up period.
Active_comparator: Posnick Modification Group
Patients undergoing orthognathic surgery with bilateral sagittal split ramus osteotomy (BSSO) will undergo medial mandibular osteotomy using the Posnick modification. The osteotomy will be performed according to the Posnick technique, with the modified medial osteotomy design extending posteriorly in accordance with the technique. Postoperative skeletal stability and relapse will be evaluated during the follow-up period.
