Objective: To evaluate the effectiveness of the Baha system in cases of single-sided deafness (SSD) and mild to moderate hearing loss in the better-hearing ear. Study Design: Prospective trial. Setting: Tertiary otologic referral center. Subjects and Methods: Twenty-one patients with SSD and mild to moderate hearing loss in the contralateral ear implanted with the Baha system between June 2006 and March 2008 were evaluated following Baha implantation and fitting with the Divino and Intenso processors. Pure-tone air and bone conduction thresholds, sound-field testing (aided and unaided in quiet and noise) of consonant nucleus consonant words (Northwestern University Auditory Test No. 6 words), and Hearing in Noise Test sentences were obtained. Patient satisfaction questionnaires were administered pre- and post-intervention for either device. Results: Patients with SSD and mild to moderate hearing loss in the contralateral ear showed a statistically significant improvement in all measures with the use of the Divino or Intenso processors compared with the unaided situation. Change in hearing, as measured in noise testing word recognition scores, revealed a statistically significant difference between the two aided conditions favoring the Intenso (P < 0.05). The Glasgow Benefit Inventory revealed that 91 percent of the patients reported improvement in their quality of life and would recommend the procedure to others. Conclusion: The Baha system is effective in the rehabilitation of patients with SSD and mild to moderate hearing loss in the only hearing ear. Results of the current study suggest that either the Divino or Intenso processor was successful in reestablishing hearing from the deafened side. © 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

Purpose To present the outcomes of two patients (three ears) with hyperacusis treated with round and oval window reinforcement. Materials and methods Transcanal placement of temporalis fascia on the round window membrane and stapes footplate was performed. Loudness discomfort level testing was performed. Results of pre and post-operative hyperacusis questionnaires and audiometric testing were reviewed. Results Two patients (three ears) underwent surgery. Results from the hyperacusis questionnaire improved by 21 and 13 points, respectively. Except for a mild loss in the high frequencies, no change in hearing was noted post-operatively. Both patients reported no negative effects from surgery, marked improvement in ability to tolerate noise, and would recommend the procedure to others. There were no complications. Conclusions Round and oval window reinforcement is a minimally invasive option for treating hyperacusis when usual medical therapies fail. Further studies are needed to evaluate the effectiveness of the procedure in reducing noise intolerance. © 2015 Elsevier Inc. All rights reserved.

We conducted a prospective crossover study to assess the safety and efficacy of 70% isopropyl alcohol delivered from a squeezable bottle with a specially designed tip as a weekly irrigant to reduce cerumen accumulation. Twenty patients were divided into 2 groups of 10 (20 ears in each group). The patients in group 1 instilled 70% isopropyl alcohol once a week for 2 months; this was followed by 2 months of no ear cleaning. The patients in group 2 performed the opposite routine. At each visit (0, 2, and 4 mo), cerumen accumulation was graded on a scale of 0 to 4, indicating 0, 25, 50, 75, and 100% occlusion, respectively. After the accumulation was graded, a cerumenectomy was performed. At the initial evaluation, the mean occlusion scores were 3.1 for group 1 and 3.3 for group 2-not a statistically significant difference. After the first 2 months of the study, there was a significant difference in occlusion scores between groups 1 and 2 (0.75 and 1.55, respectively; p < 0.0002). At 4 months, after the crossover, the occlusion scores were 1.15 and 0.95, respectively, not a significant difference (p = 0.38). At study's end, there were also significant differences within each group between occlusion scores obtained during the treatment and nontreatment periods (group 1: p < 0.02; group 2: p < 0.01). All patients tolerated the alcohol rinse well, and there were no cases of external otitis or other complications. We conclude that weekly irrigation with 70% isopropyl alcohol is safe and reduces the accumulation of cerumen in the external auditory canal. Routine use should decrease the number of office visits for cerumen removal and hearing aid cleaning. © 2012 Vendome Group, LLC.

Objectives: Report the immediate audiologic effect of paper patch myringoplasty to repair iatrogenic tympanic membrane perforations directly over the round window. Methods: Retrospective case-control study of 15 patients treated for inner ear disease with a MicroWick and dexamethasone for 1 month, resulting in 2-mm perforations over the round window. Paper patch myringoplasties were performed to repair the perforations. Audiograms were performed before and immediately after the paper patch myringoplasty. Results: After paper patch placement, there was a significant improvement in air-bone gap at 250 (p < 0.001), 500 (p = 0.003), and 1000 Hz (p = 0.004) and a significant improvement in bone conduction (BC) threshold at 250 (p = 0.002), 500 (p < 0.001), 1000 (p = 0.002), 2000 (p = 0.003), and 3000 Hz (p = 0.02). Conclusions: Paper patch myringoplasty improves both air conduction and BC hearing from small perforations over the round window. The decrease in BC hearing is a result of middle ear mechanics and is not a true sensorineural hearing loss. Copyright © 2011 S. Karger AG, Basel.
