OBJECTIVE(S): Posterior pharyngeal wall (PPW) injection is often employed to treat velopharyngeal deficiency (VPD). We sought to analyze the impact of PPW injection on severity of dysphagia and dysphonia.
METHODS: Retrospective chart review was conducted of patients undergoing PPW injection from 2018 to 2023 at a tertiary laryngology center. Effects on Voice Handicap Index-10 (VHI-10), Eating Assessment Tool-10 (EAT-10), soft palate closure on modified barium swallow, and auditory-perceptual measures of hypernasality and audible nasal air emission were analyzed.
RESULTS: 67 PPW injections were performed in 29 patients (11 female). Mean age was 59.4 ± 17.0 years. Etiologies were head and neck cancer (n = 23) and neurologic conditions (n = 6). 30 PPW injections were performed concurrent with intervention on the upper esophageal sphincter (25 dilations, 3 myotomies, 2 botulinum toxin injections), and 8 with a glottic procedure (6 vocal fold injections, 2 thyroplasties). Change scores were 3.87 (-6.85 to -0.89, p = .012) for VHI-10 and -3.00 (-4.75 to -1.25, p = 0.001) for EAT-10. These were statistically different from 0 for the whole cohort but not in the subset of patients undergoing concurrent voice and/or swallow surgery. Soft palate closure scores tended to be better (but not statistically significant) on MBS after PPW injection. Hypernasality and audible nasal air emission both improved after injection.
CONCLUSION: PPW injection appears to have a therapeutic effect on dysphagia/dysphonia in patients with VPD; however, many patients have multifactorial impairment. Additional study is needed to determine benefit of PPW when performed in conjunction with other procedures in this complex patient population.
