Fellowship training in otolaryngology-head and neck surgery.

Fellowship training in otolaryngology-head and neck surgery is a relatively new phenomenon that reflects the increasing complexity of clinical medicine. Despite an expansion of fellowship opportunities over the last three decades, there is still incomplete regulation and standardization of fellowship training. Approximately one third of residency graduates obtain some form of fellowship training. This article describes the fellowship opportunities that are currently available within the field of otolaryngology. Fellowship training serves as an avenue to gain further credentials and certification, although only the fields of neurotology, pediatric otolaryngology, and sleep medicine are accredited by the ACGME.
