Complications of eustachian tube balloon dilation: Manufacturer and User Facility Device Experience (MAUDE) database analysis and literature review

Abstract

AbstractObjectiveTo provide an analysis of complications following eustachian tube balloon dilation as well as their treatments and outcomes.Data SourcesPubMed, Ovid Embase, and MAUDE Database.Review MethodsA systematic approach following PRISMA guidelines was used to identify publications pertaining to balloon dilation of the eustachian tube from PubMed and Ovid Embase databases was used. Once these publications were critically reviewed, the primary outcome extracted were reported complications. Additional complications were collected in the Manufacturer and User Facility Device Experience (MAUDE) database using the product class “eustachian tube dilation device” and searching through relevant manufacturers. Complications and outcomes were compared between these sources.ResultsFifty five full‐length manuscripts involving 7155 patients were included and 98 complications reported for a 1.4% complication rate. The most frequently reported adverse events were subcutaneous emphysema of the head and neck (19%), epistaxis (12%), and acute otitis media (11%). The MAUDE search returned 18 distinct patient entries, of which 12 (67%) reported complications. The most reported complications in the MAUDE database included subcutaneous emphysema (8, 67%) and pneumomediastinum (3, 25%). The most serious complication was a carotid artery dissection reported in one patient in the MAUDE database.ConclusionEustachian tube dilation is rarely associated with complications, which nevertheless may lead to morbidity and medical emergencies. Patients and providers should recognize potential risks associated with this intervention as well as methods to manage complications.
