What to do with medialized tympanostomy tubes? A survey of pediatric otolaryngologists

Introduction: Tympanostomy tube placement is the most common surgical procedure performed in children. Medial migration of a tympanostomy tube is a rare occurrence where the tube migrates into the middle ear cavity as opposed to its normal extrusion into the external auditory canal. Whether medialized tympanostomy tubes should be surgically removed in asymptomatic patients is controversial. The objective of this study was to determine experience and management approach of medialized tympanostomy tubes among pediatric otolaryngologists. Methods: A 12-question cross-section survey was designed and distributed to the American Society of Pediatric Otolaryngology (ASPO) members. The survey study was granted McGill University institutional review board and ASPO research committee approval. The survey data were filtered and cross-tabulated. Descriptive statistics were generated. Results: 128 pediatric otolaryngologists completed the 12-question survey. The majority of respondents had experienced at least one case of medialized tympanostomy tube (90.6%). The majority of patients (82.0%) were asymptomatic. 74 out of 128 respondents (57.8%) indicated that they would not remove a medialized tube in an asymptomatic patient. However, 7.0% of those respondents clarified that they would proceed to surgical removal if the patient were undergoing general anesthesia for another surgery. 30.5% of respondents indicated that they would surgically remove the tube even if the patient were asymptomatic. 6.3% of respondents indicated that opted management in children would be based on a shared decision with parents. Most respondents (80.5%) did not experience complications with surgical removal nor with elected observation. Conclusion: There is no consensus among pediatric otolaryngologists regarding the necessity of surgically removing a medialized tympanostomy tube in asymptomatic patients. The survey suggests that both options are acceptable. If observation is chosen, it is important that parents are well informed of the potential long-term sequelae of a medialized tube and advised to consult if symptoms occur.
