Initial experience with the Sophono Alpha 1 osseointegrated implant.
2013
In the last several years, bone anchored hearing aids have proven to be useful in treating conductive and mixed unilateral or bilateral hearing loss, as well as for sensorineural unilateral hearing loss. The Sophono Alpha 1 model has the advantage of not requiring an abutment, with it being coupled by magnetism instead. We report the cases of 3 infants with congenital malformations of external and middle ear. Audiometry showed conductive hearing loss. All 3 patients were implanted with Alpha 1 model (Sophono). Patients evolved satisfactorily. After 30 days we applied the processor and the control audiometry showed a marked improvement of hearing thresholds, although without a complete closu…
Facial nerve schwannoma involving middle cranial fossa: When the unilateral sensorineural hearing loss guide to the correct diagnosis
2011
The Facial Nerve Schwannoma is a rare tumor and it seldom involved the middle cranial fossa. Facial nerve schwannoma has various manifestations, including facial palsy but unfortunately facial nerve is very resistant to compression and often facial nerve paralysis or a facial weakness are not present. We present a case of giant facial nerve schwannoma involved the middle cranial fossa without facial nerve paralysis. In these cases the unilateral hearing loss (if present) guide to a correct diagnosis.
Effekt der kontralateralen Stimulation auf evozierte otoakustische Emissionen bei akutem Hörverlust*
1994
23 patients with unilateral hearing loss and presence of TEOAE on both ears were examined with regard to the association between contralateral acoustic stimulation and evoked otoacoustic emissions. Contralateral white noise of 40 dB HL, 50 dB HL and 60 dB HL decreases the amplitude of TEOAE both at the ear with and without hearing loss. In comparison with a group of subjects with normal hearing, the decrease in the amplitude of TEOAE was less in the group of patients with hearing loss. Two paradoxical cases were found with an increase in the TEOAE amplitude in the ear with hearing loss during contralateral stimulation. It is assumed that impairment of the efferent synapses on the outer hair…
Akustikusneurinom als Ursache einer progredienten kindlichen Hörstörung
2003
Background: Neurinomas of the vestibulocochlear nerve unrelated to neurofibromatosis in children are extremely rare. Only 20 cases in children under the age of 16 are reported in the literature. Progressive unilateral hearing loss, tinnitus, vertigo and neurological deficits due to cranial nerve or brainstem compression are clinical signs. Patient and Results: We report on the case of a 12-years-old girl with an unilateral hearing loss, progressing to total deafness. Otoacoustic emissions were normal. In the MRI a large cerebellopontine angle tumor was found, identified as schwannoma of the vestibulocochlear nerve. Conclusions: The importance of MR Imaging in children with progressive unila…
[Clinical and radiological evolution of a group of untreated acoustic neuromas].
2013
Abstract Introduction The acoustic neuroma is a benign tumour that originates in the vestibular branch of the eighth cranial nerve. The main treatment is surgery, but many authors suggest that with elderly patients or in small neuromas we can opt for watchful waiting. Methods This was a retrospective study from 2007 to 2013 that included 27 patients diagnosed of acoustic neuroma that had not been treated due to the size of the tumour, age and comorbidities, or by patient choice. We evaluated overall condition, hearing thresholds, degree of canal paresis and central disorders. Results After 6 years of follow up, clinical manifestations of 18 patients remained unchanged, 5 patients underwent …
Unilateral sensorineural hearing loss in scholastic age subjects: Psychopedagogical aspects
2006
The Authors want to assess a probable significant relation between the unilateral sensorineural hearing loss and some learning difficulties and language acquisitions, often found, through our observation, in impaired children. The Authors have examined a group of subjects in their scholastic age who have this kind of hearing loss and, through several dialogues with them, they have gathered some relevant data about the difficulties that children have at school, and drawn up a questionnaire.
Beidseitige progrediente Hörminderung als Erstmanifestation eines metastasierenden Pankreaskopfkarzinoms - Kasuistik -
2001
We report the history of a patient who presented first with a progressive unilateral hearing loss and later with a bilateral deafness and an unilateral facial nerve palsy as first and only symptoms of a pancreatic adenocarcinoma. By means of magnetic resonance tomography tumor-suspect lesions in both internal auditory canals were detected. Referring to the results of further examinations these intracanalicular lesions are most probably due to rarely seen bilateral metastasis of a pancreatic adenocarcinoma in the temporal bone. In addition to this rarely diagnosed localisation of metastasis it is rather uncommon that this kind of primary malignoma had not been detected because of gastrointes…
