Abstract

Aim of the study: To analyze the positional changes of the inferior alveolar nerve after sagittal split ramus osteotomy (SSRO) and assess the impact of these changes on postoperative sensory nerve disturbances.

Material and methods: Preoperative and postoperative (one year) spiral CT scans were used to categorize the inferior alveolar nerve into the extended side (n = 30) and retrogressive side (n = 30). Measurement software was used to observe and measure positional changes of the mandibular nerve canal, followed by a comparative analysis.

Results: Post-surgical analysis revealed that the inferior alveolar nerve was displaced laterally and superiorly on the extended side, and medially and inferiorly on the retrogressive side, with statistically significant differences (p < 0.05). Correlation analysis demonstrated a significant association between nerve displacement in the first molar region and sensory nerve impairment (p < 0.05).

Conclusion: Significant positional changes in the inferior alveolar nerve were observed post-surgery, particularly on the extended migration side, with these changes being correlated with the occurrence of neurological symptoms.

期刊介绍： J Stomatol Oral Maxillofac Surg publishes research papers and techniques - (guest) editorials, original articles, reviews, technical notes, case reports, images, letters to the editor, guidelines - dedicated to enhancing surgical expertise in all fields relevant to oral and maxillofacial surgery: from plastic and reconstructive surgery of the face, oral surgery and medicine, … to dentofacial and maxillofacial orthopedics. Original articles include clinical or laboratory investigations and clinical or equipment reports. Reviews include narrative reviews, systematic reviews and meta-analyses. All manuscripts submitted to the journal are subjected to peer review by international experts, and must: Be written in excellent English, clear and easy to understand, precise and concise; Bring new, interesting, valid information - and improve clinical care or guide future research; Be solely the work of the author(s) stated; Not have been previously published elsewhere and not be under consideration by another journal; Be in accordance with the journal''s Guide for Authors'' instructions: manuscripts that fail to comply with these rules may be returned to the authors without being reviewed. Under no circumstances does the journal guarantee publication before the editorial board makes its final decision. The journal is indexed in the main international databases and is accessible worldwide through the ScienceDirect and ClinicalKey Platforms.
