We are aware that different levels

We are aware that different levels of airway obstruction could be treated step-wise as well. Our philosophy of multilevel surgery relies on three aspects: (1) if the patient shows moderate to severe complaints, (2) if the patient’s disease severity is confirmed by PSG, and (3) if the patient’s subsequent DISE assesses multilevel obstruction, a logical approach dictates simultaneous intervention of the levels of obstruction as assessed by DISE. We are convinced that our philosophy helps to avoid repeated surgery and related side effects and morbidity.
