Idiopathic sudden sensorineural hearing loss (ISSNHL) is a heterogenic disease. Multiple factors influencing aetiology and prognosis are discussed. A retrospective clinical characterisation and analysis of family history of ISSNHL patients was performed to investigate influences on the disease. 186 inpatients diagnosed with ISSNHL were characterised by health records and a standardised questionnaire. Audiograms were observed. 75 controls that had never experienced an event of ISSNHL were questioned about family members being affected by ISSNHL. 63.4% of all patients could be assigned to at least one group with similar causes of ISSNHL (noise exposure, positive family history, infectious diseases, hypothyroidism and fibromuscular dysplasia). A positive family history for ISSNHL has not been reported so far. Therefore, we accentuated the characterisation of patients with positive family history. 21.4% affirmed a positive family history. In ten families, at least two family members were reported as ISSNHL patients. In comparison with patients with negative family history, they tend to be younger, experience more events of ISSNHL and show less improvement of hearing abilities under therapeutic treatment (non-significant). Differences intensified between smokers with positive family history and non-smokers with negative family history. Differences concerning average age were statistically significant (p = 0.001). Within 75 controls 11 families were reported with one member being affected by ISSNHL. In the control group we did not detect any family with more than one ISSNHL patient. The results indicated that patients with positive family history tend to have an aggravated course of ISSNHL. Further studies should help to confirm these results and to identify environmental or genetic factors leading to ISSNHL. This might support a better understanding of the aetiology of ISSNHL and offer new possibilities for prevention and therapy.
