SALIVARY-GLAND CHORISTOMA OF THE MIDDLE-EAR

A salivary gland choristoma is an extremely uncommon tumour in the middle ear space. It appears to be a developmental abnormality and may be associated with abnormalities of adjacent structures. It usually presents with unilateral conductive deafness which may be long-standing and the tumour often pursues a benign, slow growing course. It is usually possible to excise it, but problems may arise as there may be variable associated anatomical abnormalities of the middle ear. We present the nineteenth recorded case, review the literature and discuss the management of this condition.
