ABSTRACT We evaluated the efficacy of hyperbaric oxygen (HBO) treatment in patients with sudden hearing loss unresponsive to medical treatment.
Fifty-one patients (37 males, 14 females; mean age 37 years; range 9 to 63 years) with sudden hearing loss were treated with HBO following unsuccessful medical treatment. Time elapsed from the occurrence of sudden hearing loss ranged between 15 to 45 days. Treatment included two sessions daily for the first three days, followed by a single daily session, to make 20 sessions of 90 minutes. Treatment was discontinued because of early recovery in two patients. Audiometric examinations were made at the end of every five sessions. The patients were classified according to age, gender, and audiogram curves.
The mean hearing thresholds were 75.3 dB and 65.6 dB before and after treatment, respectively. Recovery was rated as complete in two patients (3.9%), moderate in two patients (3.9%), mild in 19 patients (37.25%), and as no recovery in 28 patients (54.9%). No significant differences were found between the patient groups in terms of improvement and hearing gain (p>0.05).
We propose that HBO be resorted to when other means of medical treatment prove unsuccessful in patients with sudden hearing loss.

    Article: Therapy of hearing disorders - conservative procedures.

    ABSTRACT: A wide range of therapeutic strategies are available for the therapy of hearing disorders including pharmaceutical, acoustic, electrical, surgical, radiological, cognitive-behavioural and so-called "alternative" strategies. This review focuses on general conservative strategies and specific therapeutic approaches mainly for inner ear disorders, whereas surgical and device-based therapies including hearing aids and cochlear implants are described in other chapters in this volume.In addition to the systemic medication-based therapies for the treatment of hearing disorders, the rapidly growing field of local drug delivery to the inner ear as a promising therapeutic strategy is discussed on the background of unresolved issues. After description of non-drug-based therapeutic procedures, the conservative therapy of specific diseases and syndromes is reviewed.In general, there is a major discrepancy between promising animal studies up to regeneration and stem-cell transplantation, and uncontrolled experimental studies in humans on the one hand and the shortage of randomized controlled clinical trials with a high level of evidence on the other hand. Therefore, the review and comments on published clinical studies should assist the reader in making his/her own decision about the effectiveness of various, especially pharmaceutical treatments. From a critical analysis - particularly of the clinical studies presented - conclusions are drawn for the therapy of hearing disorders in the future.
