Hydatid disease of the head and neck

Abstract

Two cases of hydatid cyst are reported, one in the right parotid region involving the deep lobe and the other in the superficial subcutaneous tissue of the sub-mental region. Cystic swellings, where no definite preoperative diagnosis can be arrived at, call for a high suspicion rate for hydatid disease and, even in the nonendemic areas, Casoni's test and complement fixation tests should be carried out. © 1978 Association of Otolaryngologists of India.
