The purpose of this study was to assess the effectiveness of nasal surgery for continuous positive airway pressure (CPAP) failure in patients with both severe obstructive sleep apnea syndrome (OSAS) and nasal obstruction. Seventy-six male patients diagnosed with OSAS were prescribed CPAP for treatment. Sleep parameters and nasal resistance were evaluated by using standard polysomnography and rinomanometry before and after nasal surgery, respectively. Four of the 76 patients who were refractory to CPAP treatment underwent nasal surgery. However, they were able to use CPAP after surgery. In conclusion, nasal surgery may improve the tolerance of CPAP in patients with OSAS.
