The goal of this observational prospective cohort study is to learn about the natural course of central and mixed sleep apneas that develop after maxillomandibular advancement (MMA) surgery for obstructive sleep apnea (OSA) in adult patients.
The main question it aims to answer is:
Do central and mixed apneas resolve, partially resolve, or persist in the long term after MMA?
Participants will:
Undergo a first postoperative polysomnography (PSG) at 3-6 months after MMA (part of standard care).
Be invited into the study if central/mixed apneas are detected (CMAI% \>25%). Undergo a second PSG at least 12 months after MMA (extra study procedure)
