Introduction: Sleep apnoea syndrome is characterized by repeated collapse of the upper airway related to excessive snoring, morning fatigue and witnessed apnoeas. OSAHS affects 2–5% of the population. Continuous positive airway pressure therapy (CPAP) is the first line treatment for patients with obstructive sleep apnoea syndrome. An alternative approach is the upper airway surgery destined to improve the compliance. When considering the possibility of surgery as treatment, it is crucial to determinate the correct location of the collapse of the airway by nasofibroscopy and image studies (CT, MR) and to determine its severity.

Objective: Evaluate the surgical treatment results by taking as parameters the sleep apnoea episode reduction, measured by polysomnography, the increase of the airway surface and the daytime sleepiness, with a follow-up time of 1 year.

Patients and method: An assessment is made to 4 patients previously diagnosed with OSHAS that did not tolerate treatment with CPAP. Imaging studies are performed and appropriate surgical planning for bimaxilary advancement, uvulopalatlpharyngoplasty and rhinoseptoplasty is performed to all patients.

Results: Apnoea and hypopnea index (AHI) demonstrated a significant improvement, along with increase of the upper airway evidenced by imaging studies. An evaluation of the symptoms was also recorded.
