A Retrospective Review of Ventilation Tube Removal in Children

Objective Ventilation tube insertion is the primary surgical intervention in persistent otitis media with effusion. Around 7% of ventilation tubes require elective removal. The objective is to discover the tympanic membrane healing rate after ventilation tube removal and identify measures that improve this. Method Retrospective case note review performed for patients who had elective ventilation tube removed over an 8‐year period. Information gathered included if any concomitant procedure was performed to repair the tympanic membrane and final outcome of the tympanic membrane status. Results A total of 113 cases were included in this study. The average age at grommet insertion and removal was 5.8 years old and 8.3 years old, respectively. After ventilation tube removal the perforation edges were freshened in all cases. The majority of patients (84.1%) subsequently had an intact tympanic membrane. Additional procedures were performed on 19 ears, 6 with insertion of overlay absorbable material and 14 with a fat plug. Closure rate in these patients was 100%. Shah and Sheperd grommets had a significantly lower residual tympanic membrane perforation rate compared to T‐Tube and Titanium grommets. Conclusion Tympanic membrane closure rate after ventilation tube removal was 84.1%. Additional procedures, ie, overlaying of absorbable material, appear to improve the closure rate. We therefore advocate the technique. In selected cases such as T‐tube removal a concurrent fat plug myringoplasty may be appropriate.
