A Spontaneous Pneumatocele Presenting with External Auditory Canal Obstruction / 대한이비인후과학회지

ABSTRACT

A pneumatocele is an air-filled cavity in the body. In the head and neck areas, the extensive hyperpneumatization of the temporal and occipital bones is typically associated with pneumatocele formation, which results in the spontaneous collection of gas, usually air, beneath the pericranium or within the skull. We herein report a case of stenosis of the external auditory canal caused by a left mastoid pneumatocele in a 12-year-old boy who was successfully treated with left simple mastoidectomy and canaloplasty.
