ON MIDDLE-EAR DEAFNESS.

Imaging of congenital middle ear deafness.

INTRODUCTION Conductive hearing loss, in the presence of a normal external ear, is usually due to an interference with the normal transmission of sound from the tympanic membrane across the ossicular chain to the oval window. If conductive hearing loss occurs in a young child, congenital middle ear pathology is the most likely cause. MATERIALS AND METHODS High resolution computed tomography o...

Middle ear papilloma.

Papillomas are benign, however locally invasive tumors normally originated in the larynx and nasosinusal tract. These tumors can be described from their specific histological and morphologic characteristics. Recurrence is common if excision is inadequately performed. Tumors with similar histological and biological characteristics may occur less frequently in areas outside the nasosinusal tract ...

The Middle Ear

The 41 papers that compose this volume were presented at the McCollumPratt Institute Symposium in the spring of 1958. They fall into four broad categories entitled Developmental Cytology, Cellular and Tissue Interactions in Development, Problems of Specificity in Development, and Control Mechanism in Development. Many of the current leaders in developmental biology contribute to the book either...
