BACKGROUND: As autophony can be accompanied by several conditions, it is important to find co-morbidities. This paper reports a patient with Kennedy's disease (spinobulbar muscular atrophy, an X-linked, hereditary, lower motor neuron disease) having autophony as the first symptom.
CASE REPORT: A 62-year-old male presented to the otorhinolaryngology department with autophony that began 2 years previously and worsened after losing weight 3 months prior to presentation. Otoscopic examination demonstrated inward and outward movement of the tympanic membrane, synchronised with respiration. Although he had no other symptoms, facial twitching was found on physical examination. In the neurology department, lower motor neuron disease, with subtle weakness of the tongue, face and upper limbs, and gynaecomastia, were confirmed. He was diagnosed with Kennedy's disease based on genetic analysis.
CONCLUSION: Autophonia was presumed to be attributed to bulbofacial muscle weakness due to Kennedy's disease, and worsened by recent weight loss. Patients with autophony require a thorough history-taking and complete physical examination to assess the nasopharynx and the integrity of lower cranial function.
