    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.

    Cholesterol granuloma (CG) is a histologic description of foreign body giant cell formation toward cholesterol crystals. The majority of temporal bone CG is unilateral and most common in the petrous apex. Middle ear CG is usually the result of underlying ear diseases. Primary middle ear CG is very rare. Most reported CG has not been associated with familial hypercholesterolemia (FH). FH, an autosomal dominant disorder, manifests as high levels of serum cholesterol and low density lipoprotein (LDL) cholesterol. We report a rare case of FH and bilateral aggressive primary middle ear CG. This publication has been approved by the IRB, Hospital Alor Setar.
