Safety Outcomes of Balloon Dilation Eustachian Tuboplasty in Pediatric Patients: A Follow-Up Study.

Objectives: Balloon dilation eustachian tuboplasty (BDET) has gained popularity as a treatment modality for chronic eustachian tube dysfunction (ETD) in both adults and children. Although its safety and efficacy in the adult population have been well described, very few large-sample studies assessing its safety profile have been performed in the pediatric population. This study serves as a follow-up to a previously published analysis assessing the safety of BDET in the pediatric population.

Methods: Retrospective chart review of 71 pediatric patients (139 ears) aged 11 ± 7 years who underwent BDET from 2019 to 2023. Medical records were reviewed from the extended postoperative period. A standardized grading scale that assesses severity of surgical complications was used.

Results: A total of five minor complications (7%) were noted. These included transient postoperative tinnitus, hyperacusis, otalgia, nausea, and epistaxis. There were no major complications requiring repeat intervention or need for imaging or hospital admission. In all cases, these symptoms had resolved in the postoperative time frame, with majority of them demonstrating complete resolution before the first postoperative visit.When combining these findings with the previously published paper by the same institution, the overall complication rate is 6.1% with 114 total patients. All complications between both papers are considered minor with no long-term effects.

Conclusions: In this retrospective analysis, BDET is shown to be a relatively safe procedure when performed in the pediatric population. Upon review of the literature, this is the largest safety analysis of exclusively pediatric patients who underwent BDET.

Level of evidence: 4.
