The Short Split Method: A Solid Alternative to Classical Sagittal Split Osteotomy in Orthognathic Surgery: A Case Report

Abstract

ABSTRACT Background Orthognathic surgery is a surgical procedure to correct dentofacial deformities, improving function and facial aesthetics. Method This case report highlights the use of the short split sagittal osteotomy (SSSO), a modified technique proposed by Posnick, in treating a 32‐year‐old female patient presenting with retrognathia (Class II skeletal pattern) and obstructive sleep apnea. Results The patient underwent bimaxillary advancement with counterclockwise rotation and genioplasty, planned virtually via Dolphin 3D software. The surgical approach aimed to optimise occlusal function, airway space, and facial harmony while minimising potential complications. The SSSO technique, characterised by a low and short medial cut anterior to the lingula, was chosen for its advantages in reducing surgical trauma, nerve injury risk, and operative time. The patient expressed satisfaction with both functional and aesthetic results. Conclusion Literature review supports the efficacy and safety of the SSSO, citing lower rates of unfavourable splits, reduced neurosensory deficits, and reliable stability when proper fixation is applied. This case reinforces the potential of the SSSO as a viable alternative to the traditional bilateral sagittal split osteotomy (BSSO), especially in less complex mandibular corrections. Selection of surgical techniques should remain individualised, guided by patient anatomy, surgeon experience, and the specific goals of treatment.
