Long-term results of a modified expansion sphincter pharyngoplasty for sleep-disordered breathing.

Our aim was to evaluate the long-term objective and subjective results of a modified expansion sphincter pharyngoplasty (ESP) technique in patients with sleep-disordered breathing. Single center prospective study of 35 patients underwent an ESP as a primary surgical treatment between June 2012 and September 2015 at the hospital AZ Sint-Jan Bruges-Ostend. Patients were divided into non-OSAS and OSAS (AHI >5).
