Postoperative characteristics of combined pharyngoplasty and tonsillectomy versus tonsillectomy in children with obstructive sleep apnea syndrome

Abstract

Purpose: The study aims to identify the postoperative advantages of tonsillectomy in conjunction with pharyngoplasty and tonsillectomy alone in children with obstructive sleep apneas.

Methods: In a prospective observational study, patients who met the study criteria were randomly divided into two groups: tonsillectomy and pharyngoplasty group, and tonsillectomy alone group. In both groups, adenoidectomy was also performed in patients with adenoid hypertrophy. Differences in their healing processes in the pharyngeal wound and their hemorrhage proportions were compared. Furthermore, postoperative velopharyngeal function was also assessed.

Results: Pharyngoplasty together with tonsillectomy was performed in 328 children with obstructive sleep apnea from tonsillar hypertrophy, and tonsillectomy was performed in 275 children. These cohorts did not reveal any significant demographic differences between groups. Furthermore, blood loss was found to be significantly decreased in the tonsillectomy and pharyngoplasty group (P <0.01), and the healing process was markedly shorter. Postoperative velopharyngeal function was not affected.

Conclusions: Tonsillectomy in conjunction with pharyngoplasty reduced the duration of the healing process and blood loss, compared with tonsillectomy alone; however, postoperative complications did not increase. We consider pharyngoplasty in conjunction with tonsillectomy has great potential in the treatment of children with obstructive sleep apnea.
