摘要

BACKGROUND: After ear ventilation tube insertion, the tube is expected to be dislodged around 6-12 months based on different materials and types of the tube. The duration for a ventilation tube to stay functionally in place is important. Early or unexpected extrusion of ear ventilation tubes is likely to result in problems in otolaryngological practices. The objective of this study was to evaluate the possible factors affecting the duration of a ventilation tube before extrusion.METHODS: This retrospective study was conducted from January 1, 2007 to June 30, 2012. Three hundred and seventy-two cases with ear ventilation tube insertion were enrolled. We excluded patients who did not have a complete follow-up record or diagnosed with familial or genetic disorders. We analyzed factors including patients' age, gender, history of previous ventilation tube insertion, the type of tympanogram, the type of ventilation tube, local finding of tympanic membrane, hypertension, diabetes mellitus, hyperlipidemia, and post-operative ear infection.RESULTS: In this study, we found that age, sex, the type of tympanogram, hypertension and hyperlipidemia did not significantly affect the duration before ventilation tube extrusion. This duration tends to be shortened if the patient had a history of previous ventilation tube insertion (p ＜ 0.001), retraction of tympanic membrane before operation (p ＜ 0.001), the development of post-operative ear infections (p ＜ 0.05), or when a 0.89 mm sized ventilation tube, was used (p ＜ 0.001). On the contrary, diabetes was found to be a significant factor for prolonging the duration of the ventilation tube before extrusion (p ＜ 0.001).CONCLUSIONS: Five independent factors affecting the duration before ventilation tube extrusion were identified in our study. We recommend that clinicians should consider these factors before insertion of ventilation tube for better prediction of the extrusion time.
