Hearing Rehabilitation through Bone-Conducted Sound Stimulation: Preliminary Results.

 The bone-anchored hearing aid (BAHA) is a bone conduction system that transmits the sound directly to the inner ear by surpassing the skin impedance and the subcutaneous tissue. It is indicated for patients with mixed, conductive and unilateral sensorineural hearing loss who did not benefit from conventional hearing aids (HAs). Although the benefits from BAHA are well demonstrated internationally, this field still lacks studies in Brazil.

Intratympanic corticosteroid for sudden hearing loss: does it really work?

Introduction: Sudden deafness is characterized by an abrupt hearing loss of at least 30dB in three sequential frequencies in the standard pure tone audiogram over three days or less. Treatment is based on its etiology, and oral corticosteroids are widely used. Intratympanic corticosteroids are included as primary or secondary treatment when there is no improvement with the use of oral corticosteroids.

Analysis of electrically evoked compound action potential of the auditory nerve in children with bilateral cochlear implants.

Introduction: The cochlear implant device has the capacity to measure the electrically evoked compound action potential of the auditory nerve. The neural response telemetry is used in order to measure the electrically evoked compound action potential of the auditory nerve.

Objective: To analyze the electrically evoked compound action potential, through the neural response telemetry, in children with bilateral cochlear implants.

Vestibular evoked myogenic potential: its use in Sudden Sensorineural Hearing Loss.

Introduction: Sudden sensorineural hearing loss (SHL) has uncertain origin and evolution. Vestibular evoked myogenic potential (VEMP) estimates of the vestibular pathway that can not be analyzed by the other entrance examinations, which can be helpful in diagnosing the extent of hearing damage in these patients.

Objectives: To investigate the clinical applicability of VEMP in patients with SHL.

Caffeine effect in vestibular system.

Introduction: Caffeine benefits and harms in health is a very controversial subject for a scientific research.

Methods: This is a systematic literature using PubMed database linking caffeine with the following keywords: 'vestibular', 'vertigo', 'vestibular function', 'caloric tests' e 'electronystagmography".

Results: Thirty articles were found and ten were analyzed for fulfill the inclusion criteria.

Phosphodiesterase type 5 inhibitors and sudden sensorineural hearing loss.

Unlabelled: Phosphodiesterase type 5 Inhibitors, such as sildenafil, vardenafil and tadalafil have been increasingly used today and some of the users have developed sudden sensorineural hearing loss.

Objective: To present two patients with sudden deafness developed after an occasional use of the drug and review studies on the use of phosphodiesterase type 5 inhibitors and sudden hearing loss.

Method: Analytical study of two cases and review of the subject matter in the Pubmed/Medline and Bireme databases using the keywords: phosphodiesterase type 5 inhibitors and sudden deafness and its correlates in the English language.

Auditory neuropathy spectrum: the importance of adequate diagnosis.

Objective: To evaluate the prevalence of misdiagnosis of the hearing impaired children, in order to investigate the existence of Auditory Neuropathy Spectrum Disorder.

Methods: Analytical, prospective study conducted with 15 participants (30 ears) aged 10-12 years, with bilateral sensorineural hearing loss, attending a Hearing Rehabilitation Center, accompanied by a multidisciplinary team with otolaryngologist, audiologist, psychologist, teacher and social worker. The participants underwent ENT examination and audiological assessment: tympanometry, acoustic reflexes, otoacoustic emissions test and Auditory Evoked response.

Intratympanic corticotherapy and tinnitus control after sudden hearing loss.

Introduction: Sudden deafness is characterized by an abrupt onset, often idiopathic and tinnitus is present, and becomes the main complaint in up to 80% of patients.

Objective: To review carefully all studies of the past 10 years on sudden deafness and tinnitus and analyze the effectiveness of oral and intratympanic steroids for tinnitus control in eight patients with sudden deafness and severe disabling tinnitus.

Method: An analytical prospective in which 64 patients after sudden deafness with tinnitus were monitored and 08 of these suffering with severe disabling tinnitus underwent hearing evaluation and application of the Tinnitus Handicap Inventory and Visual Analogue Scale before, during and after sudden deafness treated with oral and intratympanic steroids.

Auditory monitoring by means of evaluation of the cochlea in soldiers of the Brazilian Army exposed to impulse noise.

Introduction: Exposure to continuous or impulse noise may lead to High Sound Pressure Induced Hearing Loss (HSPIHL) or to acoustic trauma in soldiers. Auditory evaluation by means of evoked otoacoustic emissions (EOAE) has been demonstrating its importance in the detection of subtle changes in cochlear function still unidentified in threshold tone audiometry in subjects exposed to noise.

Objective: Studying Distortion product otoacoustic emissions (DPOAEs) before and after exposure to impulse noise in soldiers of the Brazilian Army.
