| Abstract | Background: Pharyngeal flap (PF) surgery is effective at improving velopharyngeal sufficiency, but historical literature shows a concerning prevalence rate of obstructive sleep apnea (OSA), reported as high as 20%. Our institution has developed a protocol to minimize risk of postoperative obstructive complications and increase safety of PF surgery. We hypothesize that (1) preoperative staged removal of significant adenotonsillar tissue along with (2) multiview videofluoroscopy to guide patient-specific surgical approach via appropriately sized PFs can result in excellent speech outcomes while limiting occurrence of OSA. Methods: This was a retrospective chart review of all patients with velopharyngeal insufficiency (VPI) (aged 2-20 years) seen at the University of Rochester from 2015 to 2022 undergoing PF surgery to correct VPI. Nasopharyngoscopy was used for surgical planning and airway evaluation. Patients with tonsillar and adenoid hypertrophy underwent staged adenotonsillectomy at least 2 months before PF. Multiview videofluoroscopy was used to identify anatomic causes of VPI and to determine PF width. Patients underwent polysomnography and speech evaluation before and at least 6 months after PF surgery. Results: Forty-one children aged 8.5 ± 4.1 years (range, 4 to 18 years) who underwent posterior PF surgery for VPI were identified. This included 10 patients with 22q11.2 deletion and 4 patients with Pierre Robin sequence. Thirty-nine patients had both pre- and postoperative speech data and underwent both a pre- and postoperative sleep study. Polysomnography showed no significant difference in obstructive apnea-hypopnea index after posterior PF surgery (obstructive apnea-hypopnea index preop, 1.3 ± 1.2 events per hour; postop, 1.7 ± 2.1 events per hour; P = 0.111). Significant improvements in speech outcome were seen in patients who underwent PF (modified Pittsburgh score preop, 11.52 ± 1.37; postop, 1.09 ± 2.35; P < 0.05). Conclusions: Use of preoperative staged adenotonsillectomy as well as patient-specific PF dimensions results in effective resolution of VPI and a low risk of OSA. |
