To determine whether choosing the 'better' or the 'poorer' ear for cochlear implantation impacts performance outcome in an elderly population. Forty-two out of 73 elderly (≥ 60 years) cochlear implant users with some residual hearing in at least one ear were selected. Three criteria were used to group the patients as 'better' or 'poorer' ear implanted; (C1) based on previous use of hearing aid, (C2) pre-operative PTA, and (C3) pre-operative speech discrimination. The Glasgow Benefit Inventory (GBI) and the Hearing Implant Sound Quality Index (HISQUI) were used to measure QoL and quality of sound, respectively. The mean post-operative PTA was 38.7 ± 7.2 dBHL. In quiet, the mean disyllabic SDS at 65dBSPL was 75.4 ± 18.5, whereas the discrimination of sentences was 95.0% ± 6.9. The mean to...

Sound quality was self-evaluated using the hearing implant sound quality index (HISQUI29). HISQUI29 scores were further examined in three subsets. QoL was self-evaluated using the glasgow benefit inventory (GBI). GBI scores were further examined in three subsets. Possible correlations between the HISQUI29 and GBI were explored. Additional possible correlations between these scores and subjects' pure tone averages, speech perception scores, age at implantation, duration of hearing loss, duration of CI use, gender, and implant type were explored. Subjects derived a "moderate" sound quality level from their CI. Television, radio, and telephone tasks were easier in quiet than in background noise. 89 % of subjects reported their QoL benefited from having a CI. Mean total HISQUI29 score significantly correlated with all subcategories of the GBI. Age at implantation in...

To validate the Spanish-language version of The Hearing Implant Sound Quality Index (HISQUI19), a questionnaire for quantifying the self-perceived level of auditory benefit that CI users experience in everyday listening situations. Adult Spanish-speaking subjects with a CI were asked to complete a Spanish-language version of the HISQUI19. Reliability of the questionnaire was determined using Cronbach's α coefficient; exploratory factor analyses with a rotated (varimax) factor solution was applied to check construct validity; external validity was confirmed using Pearson's correlation. Test-re-test analysis was also performed. The MED-EL Assessment Database was used to assist in the administration, reporting, and data collection. Sixty-six of 77 subjects completed and returne...

Retrospective study. Otolaryngology department, tertiary referral hospital. Twelve adult patients with conductive or mixed hearing loss, all with previous middle ear surgery, underwent RW vibroplasty in an open cavity. Compound action potential thresholds were assessed during surgery. Surgical complications were recorded. Subjective benefit was evaluated using the Nijmegen Cochlear Implant Questionnaire (NCIQ), Glasgow Benefit Inventory (GBI), and Hearing Implant Sound Quality Index (HISQUI29) tests. Mean follow-up was 42 months (range 12-76). There was no significant change in bone conduction thresholds after surgery. Mean functional gain was 34.3 dB and speech discrimination score at 65 dB significantly improved from 14 to 83%. Extrusion of the wire link was the main su...

There are two types of piezoelectric implants: monomorphic and dimorphic; electromagnetic transduction uses a magnet, usually a rare earth magnet (e.g. samarium cobalt) and an energizing coil. This magnetic field causes the magnet to vibrate, which in turn, through the tympanic-ossicular chain, causes movement of the cochlear fluids. Electromechanical transduction is a variation of electromagnetic transduction.

Case series with chart review. La Paz University Hospital, Madrid, Spain. Forty-one patients with glottic or supraglottic squamous cell carcinoma who underwent supracricoid partial laryngectomy between 1998 and 2008 at the authors' institution. Local control rate, specific-disease survival rate, and overall survival rate. All patients were male, with a mean age of 56 years (range, 38-71 years). Forty-one percent of tumors were classified as locally advanced carcinomas (T3-T4). Thirty-three patients (80%) underwent supracricoid laryngectomy with cricohyoidoepiglottopexy. Epiglottis was resected in the remaining 8 patients. One patient died in the immediate postoperative period because of cardiac tamponade, 6 developed pneumonia, 2 had a postoperative bleeding that required reintervention, and 2 developed pharyngocutaneous fistula. The median follow-up period was 43 months. More than 85% of the patients completed more than 2 years of follow-up. Five-year actuarial local control rate was 80%, being 92% for T1-T2 tumors and 67% for locally advanced tumors. Thirty-five patients (85%) preserved their larynx. The 6 patients who underwent total laryngectomy had a local recurrence or a regional recurrence that infiltrated the larynx. No laryngectomy was performed for functional reasons. Supracricoid partial laryngectomy is an oncologically safe procedure to preserve laryngeal functions in selected patients with glottic and supraglottic carcinomas.

A retrospective review of clinical records identified 41 patients that underwent supracricoid partial laryngectomy at our institution since 1998. In all, 26 patients with a minimum follow-up of 3 months were alive with a functioning larynx. All of them accepted participation in a functional evaluation. Ninety-seven percent of the patients were decannulated, and every patient achieved oral intake. The 5-year actuarial laryngoesophageal dysfunction-free survival was 66.5%. Median Voice Handicap Index (VHI) score was 26, with 75% of patients scoring <40. The Median MD Anderson Dysphagia Inventory (MDADI) score was 92, with 75% of patients scoring ≥80. Median maximum phonation time (MPT) was 12 seconds. Median maximum intensity (Imax) was 99 dB. Supracricoid partial laryngectomy allows laryngeal function preservation at a rate similar to that of chemoradiation protocols. When a careful preoperative patient selection is performed, long-term functional results are outstanding. © 2011 Wiley Periodicals, Inc. Head Neck, 2012.

The English Glasgow Benefit Inventory (GBI) is a reliable, sensitive and validated post-intervention questionnaire that is used to determine health-related quality-of-life (QoL) in patients following ORL intervention. The GBI has been translated into eight languages including Spanish. The present study aimed to determine the internal consistency and validity of the Spanish version of the GBI in patients with a cochlear implant (CI). 121 adult Spanish speaking patients with a CI were questioned retrospectively using the Spanish GBI. Reliability of the questionnaire was determined using Cronbach's α coefficient; factor analyses were performed using principal component extraction with orthogonal rotation; and validity was confirmed using Pearson's correlation coefficient. The mean total score (mean ± standard deviation) of the GBI was 35.1 ± 23.6, 47.6 ± 28.9 for General Health, 17.9 ± 33.2 for Social Benefit and 1.7 ± 27.9 for Physical Health. The reliability was above 0.70 in all test domains. Using factor analyses a 4-factor solution that explained 63.2% of the variance was reached. The objective measures: bisyllables tested without lip-reading and without masking were correlated with the total score and the General Health subscales. The Spanish GBI is a reliable and practicable instrument for the assessment of health-related QoL in Spanish adult CI users.

Data were studied concerning demographics and audiometric evaluation in postlingually deaf adults at least 60 years of age who underwent cochlear implantation in 3 institutions. The Glasgow Benefit Inventory was used to quantify the quality of life. The patients were divided into 2 groups (those less than 70 years of age and those at least 70 years of age), and the results were also compared to those of younger adult cochlear implant recipients (less than 60 years of age). Eighty-one patients were included in this study. The mean age at implantation was 68 years (range, 60 to 82 years). Cochlear implantation significantly improved the patients' audiometric outcomes (pure tone average and speech perception; p < 0.05). The Glasgow Benefit Inventory showed a benefit overall (+36) and on the individual subscales (+49, +20, and +1). The difference in quality of life was not signi...
