Tinnitus and Hyperacusis Diagnosis
No full textThere is a great demand for robust measurements of tinnitus. Although such testing is performed routinely, response reliability has not been demonstrated. The diagnostic approach to tinnitus
presents some general problems that must be considered. First of all the different professional consistency between managing other hearing difficulties and assessing tinnitus. Moreover the
training programs do not focus on tinnitus management with the consequence of lack of adequate professional standards.
A real problem is then to develope clinical management procedures for tinnitus that can be used in a standardized fashion: the multi-dimensional character of tinnitus create many difficulties in its management and objective measurements are hard to find. Finally the frequent association of hyperacusis in tinnitus patients (the prevalence is about 40%) must be take in account early because conditions testing order and treatment.
This paper will explain our approach to tinnitus patient assessment that include three main point: aetiological diagnosis, psychometric and psychoacoustic evaluation.
The evaluation of tinnitus patients includes three inseparable aspect: the attempt of an aetiological diagnosis, the psychometric evaluation by questionnaires or interviews and the psychoacoustic assessment that is the most problematic point given the lack of objective tinnitus measurements. Finally, a special section will be dedicated to decreased sound tolerance as important aspect able to condition testing ongoing and treatment settings

No full textSurgical treatment of recurring preauricular sinus: supra-auricular approach.
No full textCongenital preauricular sinus is a malformation of the preauricular soft tissues with an incidence ranging between 0.1 and 0.9\% in Europe and the United States. It presents a high risk of recurrence when treated by a standard surgical technique (simple sinectomy), the incidence of which is reported to be between 19\% and 40\%. The supra-auricular approach, proposed by Prasad et al. in 1990, is easier to perform and presents a lower recurrence risk. Personal experience is presented in the treatment of congenital preauricular sinus with the supra-auricular approach as first choice or in the case of recurrence following previous standard surgery. This report includes a short review of the literature in order not only to focus on the supra-auricular approach and check the efficacy as far as concerns reduction of recurrence risk but also to contribute to a more widespread use of this method
[Protective effect of allopurinol in the exposure to noise pulses].
No full textFree oxygen radicals cause particularly severe tissues and organ damage. They appear to play an important role in the cochlea, mediating noise-exposure damage. In the present study 16 guinea pigs were implanted with permanent electrodes to record cochlear action potential. Eight animals were exposed to a 2-3 kHz, 125 dB SPL noise pulse, at a rate of 4 stimulations per second for 1.8 hours. Prior to noise exposure four out of eight animals were treated with a known dose of allopurinol. The remaining eight animals were used as controls. Endolymphatic malondialdehyde concentration was used as indicator of the lipid peroxidization processes exerted by the free radicals. No significant difference was found between the variations in hearing threshold and malondialdehyde concentration in the animals treated with allopurinol and then exposed to noise vs. the control group. The electophysiological and biochemical results have, therefore, demonstrated that preventative administration of allopurinol can provide valid protection vs. noise impulse damage
