Tongue-lip adhesion may be used to relieve obstructive sleep apnoea in infants with Pierre Robin sequence (PRS), but only a few studies have objectively evaluated its efficacy. The purpose of this study was to evaluate the results of tongue-lip adhesion by polysomnography.

A single-centre retrospective study was conducted in infants with PRS treated by tongue-lip adhesion from 2004 to 2015, in whom at least laryngotracheal endoscopy and polysomnography were performed. The variables collected were the syndromic diagnosis, demographic data, respiratory management before tongue-lip adhesion, symptoms, and additional airway interventions. Obstructive sleep apnoea was classified into 3 groups according to severity. Polysomnography was performed one month after tongue-lip adhesion. Statistical analysis was performed with Wilcoxon signed-rank test with a limit of statistical significance of P<0.005.

Thirty-seven subjects in whom tongue-lip adhesion was performed at a mean age of 45 days (8 to 210 days) were included. Thirty-one patients had isolated PRS and 6 patients had associated anomalies. All patients had confirmed severe obstructive sleep apnoea. All patients required respiratory support prior to surgery: 8 intubated patients, 15 patients with noninvasive ventilation and 14 patients with nasopharyngeal airways. Eight patients had bradycardia before tongue-lip adhesion. All parameters were improved on postoperative polysomnography: oxygen saturation, hypercapnia, apnoea-hypopnoea index, bradycardia (P<0.005). Only 8 patients had persistent severe obstructive sleep apnoea and required tracheostomy (n=5) or noninvasive ventilation (n=3). No significant correlation was observed between treatment success and any predictive variables.

Tongue-lip adhesion improved airway obstruction in all infants with PRS and resolved obstructive sleep apnoea in 29 patients. However, 8 patients required additional airway interventions.
