Abstract

Nasal airway patency plays a critical role in the pathogenesis of obstructive sleep apnea syndrome (OSAS). Recent studies have shown that nasal obstruction is an independent risk factor for OSAS and that its surgical correction generally has a positive impact on OSAS and its related symptoms. As the indication of nasal surgery for continuous positive airway pressure (CPAP) -intolerant OSAS patients suffering from nasal obstruction, nasal resistance is valuable. A value exceeding around 0.38Pa/cm3/sec in nasal resistance is thought to be suitable for nasal surgery for these patients. As the pharyngeal morphological indication of nasal surgery for OSAS patient suffering from nasal obstruction, nasal surgery is effective in those with a high-positioned soft palate and/or a wide retroglossal space. Regarding the effect of nasal surgery in the inferior turbinate, some papers indicate that submucosal resection results in the greatest increases in airflow and nasal respiratory function with the lowest risk of long-term complications.
