One-stage nasal and multi-level pharyngeal surgery for obstructive sleep apnoea: safety and efficacy

  • Kenny P Pang (a1)

Abstract

A collapsible airway is often the common denominator in sleep-disordered breathing (SDB). The upper respiratory tract includes the nasal passage, nasopharynx, oral cavity, oropharynx, base-of-tongue region and the hypopharynx. It is believed that the highest amount of resistance in the upper respiratory tract is in the nasal cavities, and particularly the nasal valve. Most authors believe that when considering surgical options for patients with obstructive sleep apnoea (OSA) it is imperative to correct nasal pathology together with the other sites of airway obstruction. In this retrospective study, I sought to investigate the safety and efficacy of one-stage nasal and multi-level pharyngeal surgery. I compared two groups of patients: group 1, receiving one-stage nasal and multi-level pharyngeal surgery; and group 2, receiving only multi-level pharyngeal surgery. In group 1, nine out of 12 patients (75 per cent) met the criteria for surgical success, with a mean pre-operative apnoea-hypopnoea index (AHI) decreasing from 36.3 to 8.9 post-operatively (p<0.0002), while in group 2, 25 out of 40 patients met the surgical success criteria (62.5 per cent), with their mean AHI decreasing from 52.6 to 10.2 (p<0.0000). When comparing the surgical success rates between the two groups, it was not statistically significant, at p>0.106. There were no postoperative respiratory-related complications despite having bilateral nasal Merocel (tampon) packing in place (in group 1), and none of the patients in either group had any desaturation, hypoxaemia, apnoea or OSA-related complications. This series suggests that, with adequate post-operative monitoring, it is both safe and efficacious to perform both nasal and multi-level pharyngeal surgery in the one surgical session.
