Abstract

Objective

Eustachian tube dysfunction is a known complication following radiotherapy to the head and neck region. Unfortunately, treatment options are limited, with significant associated morbidity. Balloon Eustachian tube dilatation has been used successfully to treat Eustachian tube dysfunction; hence, this study aimed to determine the safety and efficacy of this method in treating Eustachian tube dysfunction in post-radiotherapy patients with nasopharyngeal carcinoma.

Method

This interventional cohort pilot study on patients with Eustachian tube dysfunction compared those with nasopharyngeal carcinoma to patients without. Outcome assessment was based on tympanometry type and Eustachian Tube Dysfunction Questionnaire score.

Results

A total of 14 ears (12 patients) were tested. Only 14 per cent of the nasopharyngeal carcinoma cohort showed improvement, while 71 per cent of the non-nasopharyngeal carcinoma group were successfully treated. No significant adverse effect was reported in any patient during this study.

Conclusion

Balloon Eustachian tube dilatation was not shown to be beneficial for post-radiotherapy Eustachian tube dysfunction in nasopharyngeal carcinoma patients in the preliminary stages of this pilot study.
