Hearing aids-external electronic devices used to help individuals with hearing loss-traditionally consist of a microphone, an analog-to-digital converter, a digital signal processor, a digital-to-analog converter, and a receiver that delivers an acoustic signal into the external auditory canal. In 2008, 97% of all hearing aids sold used digital processing. Catherine V. Palmer, PhD, provides a review of current digital hearing aids.
Experts Debate Pediatric Airway Issues

Infantile hemangiomas and LMs differ from one another in prevalence, etiology, and clinical presentation, but both may be undergoing potential shifts in treatment, depending on research outcomes.
Multidisciplinary Treatment Needed for Vascular Anomalies
Few medical conditions that otolaryngologists treat possess the breadth of heterogeneity of vascular anomalies. The size of lesions ranges from minute to massive, and the manifestations range from trivial to life-threatening, with the severity of symptoms not always proportional to the size of the lesion.
Superior Canal Dehiscence Linked to Abnormal ECoG Readings
