Laryngopharyngeal reflux leads to adverse short-term outcomes of vocal fold polyp patients after office-based transnasal vocal fold polypectomy.

Objectives: This study aimed to explore the influence of laryngopharyngeal reflux on the features of vocal fold polyps and prognosis after office-based transnasal vocal fold polypectomy.

Methods: Eighty-four vocal fold polyp patients were retrospectively analysed. Patients were assigned to laryngopharyngeal reflux or non-laryngopharyngeal reflux groups using pre-operative Reflux Symptom Score-12.

Results: The laryngopharyngeal reflux group had significantly higher pre-operative Reflux Sign Assessment scores, worse lifestyle and worse eating habits than the non-laryngopharyngeal reflux group. After office-based transnasal vocal fold polypectomy, the Reflux Symptom Score-12 and Reflux Sign Assessment score decreased in both groups, although the laryngopharyngeal reflux group still had higher values. The non-laryngopharyngeal reflux group had better vocal fold morphology recovery than the laryngopharyngeal reflux group. Multivariate logistic regression analysis demonstrated that smoking and a higher pre-operative Reflux Symptom Score-12 score were independent risk factors for poor prognosis.

Conclusions: Laryngopharyngeal reflux is detrimental to vocal fold recovery of vocal fold polyp patients following office-based transnasal vocal fold polypectomy. For vocal fold polyp patients with laryngopharyngeal reflux, lifestyle and diet guidance should be focused.
