The objective of this study is to assess the validity of ASSR as a complementary diagnostic test for peripheral hearing loss by proving a significant correlation between behavioral thresholds and ASSR. The design used in this study is monocentric prospective study from November 2014 to April 2015. The setting used in this study is the ENT-Head and Neck Surgery Department and Geriatrics Department in a French Regional and University Hospital. The participants are patients over 75 years with cognitive impairment (Alzheimer's disease or mild-cognitive impairment) with a Mini-Mental State Examination score under 27/30 and without hearing aids. Exclusion criteria were: otoscopic and middle ear abnormalities, retro-cochlear lesion, other types of dementia, and central nervous system disease altering cerebral lateralization. The intervention used in this study is pure-tone audiometry, speech audiometry, dichotic listening test, and auditory steady-state responses recording. The correlations between these exams were studied with Pearson's correlation coefficient and Student's t test. Results were significant if p < 0.05. Twenty-three ears were analyzed from 12 patients. There were six women and six men with cognitive impairment, mean age 82.1 (±4.6) years, and mean MMSE score that was 21.3/30 (±5.7). The correlation between pure-tone audiometry and ASSR was significant for all frequencies: r = 0.55 (p = 0.006) for 500 Hz, r = 0.58 (p = 0.005) for 1000 Hz, r = 0.61 (p = 0.003) for 2000 Hz, and r = 0.66 (p = 0.002) for 4000 Hz. There was no significant correlation between the MMSE and the difference between ASSR and PTA on each frequency. The dichotic listening test showed a right ear advantage (50.9 %, p = 0.039). The ASSR in patients with cognitive impairment and understanding troubles is a promising complementary technique to estimate the hearing thresholds.
We herein report our experience with the management of laryngoceles using transoral robotic surgery (TORS). A bicentric retrospective study was conducted from November 2009 to September 2015. The inclusion criteria were treatment of a laryngocele by TORS and no malignancy on definitive histopathology. Surgery was performed using the Da Vinci (Intuitive) surgical robot. Surgical methods and post-operative outcomes were evaluated. Eight patients (four men and four women) presenting with a laryngocele (one bilateral case) were included (mean age 61.8 years). There was one covering tracheotomy. The average post-operative stay was 3.75 days. Three patients treated for a combined laryngocele had a nasogastric feeding tube inserted for 5 days. One patient experienced late laryngeal bleeding that required surgical treatment. TORS may offer an efficient treatment option for laryngoceles. The use of precise and flexible instruments and a three-dimensional camera allow fine dissection of these tumours, preserving the glottic space and vocal function, even for combined laryngoceles extending deep within the neck.Evidence level: 4.
In non-traumatic vocal-fold paralysis in adult patients, without recovery of vocal-fold motion, a minimum three years' regular follow-up is recommended.
