[Influence of nasal obstruction on obstructive sleep apnea syndrome].

OBJECTIVE

To explore the influence of nasal obstruction on obstructive sleep apnea syndrome (OSAS).

METHOD: 18 patients with OSAS concomitant with nasal obstruction and palatopharyngeal obstruction were only operated on nasal cavity to improve ventilation, followed-up six months.

RESULT: 12 cases were reported remission, 4 cases efficient, and 6 cases unchanged, apnea and hypopnea index (AHI) decreased from 29.9 +/- 2.1 to 22.8 +/- 2.7, and lowest SaO2 (LoSaO2) increased from (75 +/- 2.9)% to (83.4 +/- 2.3)%. There was no significant difference for body mass index (BMI), but there was significant difference for preoperative AHI between non-effective groups and effective groups.

CONCLUSION

Nasal obstruction is an important pathogenic factor. It is a necessary method to prevent OSAS by relieving nasal obstruction earlier and operation on nasal cavity is an effective method for the management of OSAS concomitant with nasal obstruction.
