Nasal surgery versus pharyngeal surgery in the treatment of obstructive sleep apnea

Abstract

The endemic spread of obesity and unhealthy behaviors of modern society led to revisiting the real prevalence related to obstructive sleep apnea. Recent data support a paradigm shift towards individually tailored treatments which include functional surgery of the upper airways. This paper presents the results of a randomized interventional, prospective study on 68 patients referred by the general practitioner for obstructive sleep apnea. The eligible cohort consisted of 28 patients who were offered functional surgery for definitive relief of obstructive symptoms. After topographic diagnosis of the obstruction site and grading of the severity of the obstructive sleep apnea, the eligible lot was randomized for either nasal surgery or pharyngeal surgery. Subjective and objective measurements were carried out at presentation and three months after surgery. Results showed a significant reduction in AHI (more than 50%) after functional surgery, with marginal benefit for those treated with nasal surgery. Functional improvement is unequivocal for both surgical methods, but the superior results reported in the nasal surgery group could be related to the relatively small size of the study group. The involvement of a larger cohort in subsequent studies with a similar design could confirm these results.
