09h20 Nasal Width Changes Following Orthognathic Surgery with Marginal Intra-Sulcular Incisions: A Cone Beam CT Analysis

Orthognathic surgery, such as LeFort I osteotomy, is frequently used to correct maxillo-mandibular dysmorphia but can lead to changes in nasal morphology, including an increase in nasal width. This study aims to evaluate the impact of using marginal intra-sulcular incisions, rather than conventional vestibular incisions, on nasal width changes following orthognathic surgery. The objective is to determine whether this alternative incision approach affects nasal outcomes.

Using cone beam computed tomography (CBCT), preoperative and postoperative assessments will be conducted to quantify changes in nasal width. This research aims to provide insights into optimizing surgical techniques to minimize undesired nasal alterations and enhance aesthetic results.
