Objectives To assess the complications of ventilation tubes that were retained in children for 2 years or longer and the necessity of removal.
Design A retrospective chart review of all patients who underwent ventilation tube removal from 1997 to 2000, with the exclusion of patients with craniofacial anomalies.
Setting A tertiary children's hospital.
Patients One hundred twenty-six children with ventilation tubes that were retained for 2 years or longer.
Interventions Ventilation tube removal and tympanic membrane (TM) patching.
Main Outcome Measures Otorrhea, formation of granulation tissue, TM perforation, development of cholesteatomas, and tube reinsertion.
Results A total of 126 patients aged 2 to 14 years (59 girls and 67 boys) underwent removal of their ventilation tubes after 2 years or more. The patients were divided into 2 groups. Group 1 included 67 patients (29 girls and 38 boys) who were younger than 7 years at the time of tube removal. The tubes were retained for 2 to 5 years (mean retention time, 3.3 years). Group 2 included 59 patients (30 girls and 29 boys) aged 7 years and older at the time of tube removal. The tubes were retained for 2 to 10 years (mean retention time, 4.2 years). Complications such as otorrhea, formation of granulation tissue, and TM perforation were seen in 10.3%, 13.8%, and 5.2% of the patients with tube retention of 2 to 3 years, compared with 40.0%, 40.0%, and 46.7% of patients with tube retention of more than 5 years. In group 1, transient otorrhea, formation of granulation tissue, and TM perforation occurred in 13.4%, 7.4%, and 6.0% of the patients, respectively, after 2 years of tube retention. In group 2, similar complications occurred in 23.7%, 25.4%, and 27.1% of the patients, respectively. Forty-six patients in group 1 underwent TM patching (31 with paper and 15 with absorbable gelatin film, with a success rate of 91.3%; however, 8 patients (11.9%) required tube reinsertion. In group 2, patching of the TM was done in 40 patients (13 with paper, 24 with absorbable gelatin film, and 3 with fat), with a success rate of 67.5%. Tube reinsertion was necessary in 1.7% of the patients in group 2. No cholesteatoma was encountered.
Conclusions Higher complication rates are seen in children when ventilation tubes are retained longer than 2 years. Children 7 years and older have a higher incidence of complications from the tube retention than children younger than 7 years. Early removal of ventilation tubes in children younger than 7 years of age, when the risk for otitis media is still present, may result in the need for tube reinsertion.
