First Experiences With the Ponto⢢ SuperPower Osseointegrated Device
2018
Osseointegrated hearing devices Power and SuperPower present indications for bone thresholds of 55 and 65 dB respectively. We conducted a prospective observational study of a series of six cases with mixed hearing loss for whom implantation of the DAO Ponto™ Super-Power was performed. Tonal and verbal evaluations without and with background noise (HINTS) were performed prior to implantation and six months after adaptation. All the participants showed improvement in tonal and verbal results, varying according to the degree of contralateral hearing loss. The verbal results with background noise were noteworthy, where most of the patients obtained a signal-to-noise ratio between 2 and 4 dB. Th…
Evolution of otosclerosis to cochlear implantation.
2011
Abstract Introduction Otosclerosis is an osteodystrophy of the labyrinthine capsule producing conductive hearing loss. If the process invades the cochlea, a sensorineural hearing loss usually takes place. The cochlear implant is a good alternative in these patients. Objective To ascertain the behaviour of cochlear implantation (CI) in otosclerosis. Material and methods We reviewed a database of 250 patients who underwent CI, performing a retrospective study of 13 patients with clinical, audiological and/or imaging findings of bilateral otosclerosis. The 26 ears were studied as to their natural history, previous surgeries, evolution to profound hearing loss, computed tomography (CT) images, …
Haploinsufficiency of 16.4 Mb from chromosome 22pter-q11.21 in a girl with unilateral conductive hearing loss.
2009
We present the postnatal diagnosis of a de novo der(18)t(18;22)(p11.32;q11.21)pat, resulting in an unbalanced 45,XX,der (18)t(18;22) karyotype in a girl with conductive hearing loss on the left and ptosis of the right upper eye-lid. Unilateral ptosis was also observed in the patient’s 2 years and 8 months younger sister, who grows noticeably faster and appears to be a much quicker learner. After speech therapy the patient was eventually placed in normal school. The haploinsufficient 16.4-Mb region on chromosome 22pter→q11.21 contains 10 genes as well as many predicted genes, pseudogenes, and retrotransposed sequences with unknown functions. This observation may prove useful for prenatal dia…
Eustachian tube dysfunction in OSMF- often present seldom discovered
2014
Objectives: To evaluate the effect of OSMF on the eustachian tube function and to correlate it with various grades of the disease. Study Design: Twenty OSMF patients (40 ears) and 20 healthy controls (40 ears) were evaluated for eustachian tube function by eustachian tube function test, tympanometry and audiometry. Results: The audiometric and tympanometric analysis showed no significant differences in hearing abilities of OSMF patients and controls and between various grades of OSMF, indicating no hearing impairment. However, eustachian tube function test revealed a statistically significant difference in eustachian tube function in OSMF patients and controls. Further, there was a signific…
