Description

There are triggers behind non-organic hearing loss, for example accidents, or school problems. Recognizing and eliminating the triggers would contribute to improved hearing. The relationship between the timing of eliminating triggers and the length of time for hearing improvement was evaluated. The subjects were 38 patients (25 females) who were diagnosed over the previous 9 years and had not undergone treatment. They ranged in age from 7 to 72 years (median of 14 years). The patients were classified according to whether their triggers were eliminated soon after hearing loss or not. No differences were found in the sex distribution, age and laterality between the two groups. Furthermore, no differences were found between groups in hearing levels at the first or last visits, or in the improvement in hearing between these visits. However, the period required for hearing levels to stabilize was significantly shorter in patients whose triggers were eliminated early (28.5 days vs. 214 days, p=0.011). The observation period was also shorter in the group with early elimination of triggers (67 days vs. 350 days, p=0.0014). This study revealed that early elimination of triggers led to earlier improvement in patients with non-organic hearing loss.
