Laryngomalacia is the most common congenital laryngeal anomaly. Usually the symptoms are mild, do not interfere with growth and development and resolve spontaneously. Occasionally it results in failure to thrive, apnea and cardiopulmonary disease. ⋯ Their pre-operative symptoms resolved after surgery. The cases, indications and complications reported in the literature are discussed. We conclude that in certain severe cases of laryngomalacia, epiglottoplasty is a useful and safe tool.

An etiologic paradigm of hearing loss for industrial workers is introduced as having two major components, one being occupational and the other extra-occupational. The extra-occupational factors include age, noise exposure outside the work place, trauma, ear disease and ototoxic drugs. The work-related factors include occupational noise, whole body vibration, work-related diseases and toxic exposures. Within this framework, a review of the epidemiology of hearing loss examines the possible relationships between hearing loss and these factors.

Hemangiomas are the most common benign tumor of childhood occurring in the head and neck. The vast majority of these lesions are noted in the neonatal period and are a frequent cause for parental concern. ⋯ A review of the literature is presented with anatomic descriptions, classification, and discussion of treatment modalities. Special emphasis is placed on the diagnosis and treatment of the often life-threatening subglottic hemangioma.
