OBJECTIVES: To understand the presence of transient autophony symptoms in patients being treated for severe anorexia nervosa (AN), and whether those symptoms were due to patulous eustachian tube (PET).
METHODS: A prospective observational study was performed in patients requiring admission for treatment of severe AN. All enrolled patients completed The Eustachian Tube Dysfunction Questionnaire (ETDQ-7) and were screened for symptoms of autophony. If patients reported autophony and had a score of ≥14.5 on the ETDQ-7 they were asked to undergo comprehensive audiological testing and an evaluation with an otolaryngologist.
RESULTS: Of the 73 patients enrolled in the study, 35 patients (44%) reported autophony and 36 (49%) scored 14.5 or higher on the ETDQ-7. Of the 16 (22%) patients who had both autophony and an ETDQ-7 score of 14.5 or higher, 7 patient s (representing 11 symptomatic ears) underwent evaluations by audiology and otolaryngology. Every evaluation of a symptomatic ear revealed objective evidence of PET. Nine of 11 (81.8%) symptomatic ears had subjectively resolved within 12 days of admission after nutritional rehabilitation and weight gain.
CONCLUSION: Transient autophony in severe AN patients is due to PET, and was present in at least 8% of patients within our cohort. Further study is warranted to understand the quality of life impact and pathophysiology of transient PET in this patient population.
