- Speech Perception Performance of Double Array Multichannel Cochlear Implant Users With Standard and Duplicated Maps in Each of the Arrays(2013) BENTO, Ricardo Ferreira; GOFFI-GOMEZ, Maria Valeria Schmidt; TSUJI, Robinson Koji; FONSECA, Anna Carolina de Oliveira; IKARI, Liliane Satomi; BRITO NETO, Rubens Vuono deObjective: The present investigation evaluated the speech perception performance of patients with ossified cochlea implanted with the 24M Double Array cochlear implant, using standard and duplicated maps in each of the arrays. Study Design: Retrospective case review. Setting: Tertiary referral center. Patients: Sixteen subjects received a Double Array cochlear implant. Among these, 9 fulfilled the following inclusion criteria: bilateral severe-to- profound postlingual deafness; bilateral obliterated cochlea, as shown by a computed tomographic scan; and a minimum age of 14 years to ensure reliable responses in the behavioral tests with the 3 tested maps. Intervention: Rehabilitative. Main Outcome Measures: The speech perception performance with the 2 arrays was compared with that with a basal array duplicated map and an apical array duplicated map. Three maps were fitted: the default map with both arrays activated, a double channel map using only the electrodes of the basal array, and a double channel map programmed only with the electrodes of the apical array. The test battery was composed of a vowel test, a 4-choice word test, and sentence recognition in quiet. Results: Statistical significance was reached in comparison the all tests in all programming conditions. Speech recognition in the standard map with both electrode arrays activated showed the highest scores. Conclusion: Performance with the 2 split electrode arrays was superior to those with the single arrays, regardless of the duplication of channels.
- BAHA (Bone Anchored Hearing Aid) indicações, resultados funcionais e comparação com cirurgia reconstrutiva de orelha(2012) BENTO, Ricardo Ferreira; KIESEWETTER, Alessandra; IKARI, Liliane Satomi; BRITO, RubensINTRODUCTION: The bone-anchored hearing aid (BAHA) is a bone conduction hearing device that transmits sound directly into the inner ear. It is mainly used in patients with conductive hearing loss associated with aural atresia, but it is also used in those with mixed and sensorineural hearing loss. GOALS: To review the main indications for BAHA, to analyze the audiometric results and its benefits for patients and compare them with other treatment modalities, and to compare the literature data with our sample of 13 patients. METHOD: The research was performed using a database covering works in English, Spanish, and Portuguese, with no limitations in the years when the procedures were performed. We compared the literature data with our results for the 13 patients who underwent BAHA implantation between the years 2000 and 2009. RESULTS: Most of the studies showed that BAHA has great advantages over reconstructive surgery in terms of hearing results, complications, and disease recurrence. The postoperative results for our 13 patients were satisfactory and comparable with the results from the literature, with closure of the air-bone gap in 7 patients and achieving an air-bone gap of 10 dB in 6 patients. No postoperative complications were observed. CONCLUSION: BAHA is a better treatment option than reconstructive surgery for patients with bilateral deafness. It is a relatively simple surgical procedure with few complications and good hearing results. Recent studies have examined its use in conductive and unilateral sensorineural hearing loss.
- Post-lingual deafness: benefits of cochlear implants vs. conventional hearing aids(2012) BITTENCOURT, Aline Gomes; IKARI, Liliane Satomi; TORRE, Ana Adelina Giantomassi Della; BENTO, Ricardo Ferreira; TSUJI, Robinson Koji; BRITO NETO, Rubens Vuono deThe technological advances in cochlear implants and processing strategies have enabled subjects affected by severe to profound hearing loss to hear sounds and recognize speech in various different degrees. The variability of hearing outcomes in subjects with post-lingual deafness has been significant and cochlear implant indications have been extended to include an ever larger population. Objective: This paper aims to look into the groups of post-lingual deafness patients to find where cochlear implants have yielded better outcomes than conventional hearing aids. Materials and Methods: Review the literature available on databases SciELO, Cochrane, MEDLINE, and LILACS-BIREME. The publications selected for review were rated as A or B on evidence strength on the day of the review. Their authors analyzed and compared hearing aids and cochlear implants in populations of post-lingually deaf patients. Study Design: Systematic review. Results: Eleven out of the 2,169 papers searched were found to be pertinent to the topic and were rated B for evidence strength. Six studies were prospective cohort trials, four were cross-sectional studies and one was a clinical trial. Conclusion: The assessment done on the benefits yielded by post-lingually deaf subjects from cochlear implants showed that they are effective and provide for better results than conventional hearing aids.
