Evaluation of nasal cavity ventilation expansion techniques on obstructive sleep apnea hypopnea syndrome with nasal obstruction

Abstract

Objective: To investigate the effect of nasal cavity ventilation expansion techniques in treatment of obstructive sleep apnea hypopnea syndrome (OSAHS) with nasal obstruction. Methods: Thirty-two OSAHS patients with nasal obstruction hospitalized from January 2017 to January 2018 in Department of Otorhinolaryngology Head and Neck Surgery, Provincial Hospital Affiliated to Anhui Medical University were selected, with 28 males and 4 females, aged 40.3±8.5 years old (x±s), and treated with individualized nasal cavity ventilation expansion techniques. Nasal acoustic reflex and resistance examination, polysomnography (PSG) monitoring were performed before and three months after operation. Nasal obstruction symptom evaluation (NOSE) and Quebec sleep questionnaire (QSQ) were completed as well. The nasal acoustic reflex, nasal resistance, NOSE, QSQ score, apnea hypopnea index (AHI) and lowest arterial oxygen saturation (LSaO(2)) before and after operation were compared and analyzed. SPSS 22.0 software was used for statistical analysis. Results: After the operation, the total nasal resistance and total score of NOSE scale of patients decreased significantly as well as the total score of QSQ scale increased significantly ((0.140±0.043) kPa·s/L vs (0.277±0.067) kPa·s/L, 9.84±4.11 vs 53.00±11.57, 5.67±0.43 vs 3.86±0.46, t value was 10.687, 18.035, -16.904, respectively, all P<0.05), and the scores of five dimensions increased in varying degrees. Among the indexes of PSG, there was no significant difference in AHI and LSaO(2) values before and after operation, but AHI decreased and LSaO(2) increased. Conclusion: Nasal cavity ventilation expansion techniques can effectively alleviate the symptoms of nasal obstruction in OSAHS patients and improve their sleep and quality of life.
