Quality of Life Assessment Following Maxillomandibular Advancement Surgery for Obstructive Sleep Apnea

Abstract Purpose While maxillomandibular advancement (MMA) surgery is highly efficacious for management of obstructive sleep apnea (OSA), little information exists regarding the subjective impact of this treatment modality. The present study was undertaken to investigate the impact of MMA on patient-perceived quality of life (QOL) in OSA. Methods A retrospective cohort study of patients treated with MMA for OSA between May 2010 and April 2015 was performed. The primary outcome measure was a change to QOL detected by the Ottawa Sleep Apnea Questionnaire (OSA-Q), which assesses MMA-related changes to QOL on a 5-point Likert scale. The secondary outcome measure was a change to the Apnea Hypopnea Index (AHI). Results Twenty-two patients participated in the present study. Mean maxillary and mandibular advancement were 8.36 and 11.08mm, respectively. AHI decreased from 42.4 to 6.9 events/h (p < 0.001), postoperatively. QOL improved significantly following MMA (OSA-Q score: 3.98 ± 0.35, p < 0.001). Sleep quality (4.35 ± 0.63), daytime function (4.13 ± 0.46), physical health (4.19 ± 0.45), mental and emotional health (4.02 ± 0.55), and sexual health (3.78 ± 0.62) categories all improved postoperatively (p < 0.001). MMA-related side effects did not adversely affect QOL. Conclusion MMA for OSA significantly improves patient’s subjective overall quality of life, with few MMA related side effects.
