RESUMEN
Over the past 30 years, hearing care clinicians have increasingly relied on cochlear implants to restore auditory sensitivity in selected patients with advanced sensorineural hearing loss. This article examines the impact of intervention with cochlear implantation in children and adults. The authors report a range of clinic-based results and patient-based outcomes reflected in the reported literature on cochlear implants. The authors describe the basic assessment of the physiologic response to auditory nerve stimulation; measures of receptive and productive benefit; and surveys of life effects as reflected measures of quality of life, educational attainment, and economic impact.

OBJECTIVE: To describe a case of pneumolabyrinth secondary to tympanic membrane/ossicular trauma and the subsequent recovery of sensorineural hearing loss managed with conservative measures. PATIENTS: A 15-year-old boy presented to an outside hospital with signs and symptoms of acute hearing loss, vertigo, and tinnitus after penetrating injury to his right tympanic membrane. In addition, computed tomography demonstrated air density within the vestibule. INTERVENTIONS: The patient was managed conservatively with bed rest, avoidance of straining, corticosteroids, and antibiotics. MAIN OUTCOME MEASURES: Computed tomography, audiologic testing. RESULTS: Patient recovered near-normal hearing subjectively. There was closure of the air-bone gap (Asunto(s)

RESUMEN
OBJECTIVES: The purpose of this study is to evaluate the effectiveness of Bone Anchored Cochlear Stimulator (BAHA) in transcranial routing of signal by implanting the deaf ear. Study design and settings Eighteen patients with unilateral deafness were included in a multisite study. They had a 1-month pre-implantation trial with a contralateral routing of signal (CROS) hearing aid. Their performance with BAHA was compared with the CROS device using speech reception thresholds, speech recognition performance in noise, and the Abbreviated Profile Hearing Benefit and Single Sided Deafness questionnaires. RESULTS: Patients reported a significant improvement in speech intelligibility in noise and greater benefit from BAHA compared with CROS hearing aids. Patients were satisfied with the device and its impact on their quality of life. No major complications were reported. Conclusion and significance BAHA is effective in unilateral deafness. Auditory stimuli from the deaf side can be transmitted to the good ear, avoiding the limitations inherent in CROS amplification.
