Does the Kushida Morphometric Model Predict Outcomes following Maxillomandibular Advancement Surgery for Obstructive Sleep Apnoea? Abstract

Objective: The primary aim of this study was to explore the predictive potential of the preoperative Kushida index score and subsequent outcome following maxillo-mandibular

advancement surgery (MMA). Secondarily we looked at how well the Kushida values of our OSA patients matched the morphometric models diagnostic thresholds.

Methods: We performed a retrospective analysis of patients who underwent MMA for OSA at our institution. Kushida morphometric scores were calculated using the described formula: P+(Mx-Mn)+3×0J+3×[Max (BMI-25)]×(NC÷BMI). Regression analysis was performed to explore the possible association between Kushida Index Score and outcomes variable of postoperative apnoea / hypopnea indices (AHI) and Epworth sleepiness scores (ESS). Results: We identified 28 patients with compete data available for analysis. The mean age

was 45 years (SD 6) with mean BMI of 28 (SD 3). All, but one patient underwent Bimaxillary procedure with or without genioplasty, with a mean advancement of 8.5mm (SD 2). The mean Kushida index score in our sample was 79 (SD 14). 89% of patients had postoperative AHI30/hr). Epworth Sleepiness Scale (ESS) is a validated questionnaire to subjectively assess the degree of daytime sleepiness in OSA. The
