A Case of Subcutaneous Emphysema and Pneumomediastinum After Balloon Eustachian Tuboplasty

Abstract

The Eustachian tube is a passage that connects the middle ear to the nasopharynx and regulates the pressure within the middle ear. If there is persistent inflammation in the mucosa due to infection or allergic reactions, the opening of the Eustachian tube may not function properly, leading to obstructive Eustachian tube dysfunction. If symptoms persist even after three months of conservative treatment, balloon Eustachian tuboplasty may be considered. Although rare, severe complications such as subcutaneous emphysema, pneumomediastinum, and pneumothorax can occur, but there have been no reported cases of such complications in the Republic of Korea so far. Here, we present a case of a 52-year-old male who developed subcutaneous emphysema and pneumomediastinum after undergoing balloon Eustachian tuboplasty and discuss prevention and treatment for possible complications following the procedure.
