Swallowing outcomes following division of pseudo-epiglottis resulting from vertical pharyngeal closure in laryngectomy
HEAD AND NECK-JOURNAL FOR THE SCIENCES AND SPECIALTIES OF THE HEAD AND NECK(2023)
摘要
BackgroundVertical closure of the pharynx after laryngectomy can result in an outpouch of the anterior wall of the neopharynx below the tongue base, called a pseudo-diverticulum. The prolapsed mucosa that separates the rest of the neopharynx from the pseudo-diverticulum is termed a pseudo-epiglottis. MethodsProspective study of patients with pseudo-epiglottis. M. D. Anderson Dysphagia Inventory (MDADI) scores were used to assess swallowing outcomes pre- and post-pseudo-epiglottis division, including minimally clinically important difference (MCID) assessment. ResultsOf 16 patients with a pseudo-epiglottis, 12 had dysphagia (75%). Symptomatic patients had significantly worse global MDADI and subscale scores. After division, the mean composite MDADI increased from 48.3 to 64.7 (p = 0.035), including a high MCID (16.4) with a similar improvement in the global question rating findings (31.1 vs. 60, p = 0.021). The MCID was significant for all MDADI subscales. ConclusionsPseudo-epiglottis formation is associated with significantly worse global and subscale MDADI scores. A clinically- and statistically-significant improvement in the MDADI scores was found following surgical division.
