OBJECTIVE We present an additional very rare case of a congenital tympanic membrane cholesteatoma (CTMC) in the adult. METHOD Case report and literature review of CTMC. CASE REPORT A 54-year old man was referred to us by his primary care physician who noted a white mass on the right tympanic membrane without prior history of otorrhea, tympanic(More)
Acoustic neuromas represent about 90% of all space-occupying lesions of the cerebellopontine angle and account for approximately 6% of all intracranial tumors. Progressive unilateral sensorineural hearing loss is the most frequent initial symptom occurring in over 90% of patients. A sudden onset of hearing loss occurs in 5%, while 5% of cases present with(More)
Laryngeal tuberculosis is considered by now a rare disease after the introduction and use of chemotherapeutic drugs the incidence of laryngeal tuberculosis an increase in the world population, including industrialized countries; this is partly due to the pandemy of the Acquired Immuno-Deficiency Syndrome (AIDS). The authors report a case of miliary(More)
Electrocochleography (ECoG) is an electrophysiologic approach to the study of hearing. In ECoG, electrical activity that originates within the cochlea or the auditory nerve is recorded. ECoG represents an evoked or stimulus dependent measure. The electrical potentials which can be analyzed in ECoG are: the cochlear microphonic potential (CM), the summating(More)
At the end of stapedioplasty, performed under local anesthesia, the surgeon usually tests the hearing function making questions to the patient turning his voice from a soft whisper to a loud tone. At the ENT Department, University of Parma Italy, a more precise method is employed in order to measure the air conduction threshold of the patient at the(More)
Brainstem evoked responses audiometry was performed on 10 newborn infants. They ranged in postnatal age from 19 hours to 5 days and in estimated gestational age from 39 to 42 weeks. Clicks of 0.1 msec duration were presented at a rate of 11.4 per second. Measurements were made at 50, 80 and 100 dB. Wave V latencies were evaluated at 50, 80 and 100 dB HL in(More)
To assess the role of magnetic resonance imaging (MRI) in the management of myelomenigocele. Spinal dysraphism or neural tube defects (NTD) encompass a heterogeneous group of congenital spinal anomalies that result from the defective closure of the neural tube early in gestation. Myelomeningocele is the most common type of NTD that is compatible with life,(More)
