Cholesteatoma is a growth of keratinizing squamous epithelium. It originates from the external layer of the ear canal (tympanic membrane). When viewed in a photo shown on the bottom right of page 1, it is a white substance that invades the middle ear cleft (the air-conditioning space that is medial to the plane of the tympanic membrane.
The authors write in the first chapter entitled General Considerations in Cholesteatoma that this disease would have been better named keratoma. Cholesteatoma has two components:
- The acellular keratin debris which forms the contents of the sac
- The matrix which forms the sac itself
The cholesteatoma matrix consists of an inner layer of keratinizing squamous epithelium and an outer layer of sub-epithelial connective tissue (perimatrix).
Of the two components, the matrix is the biologically active one in cholesteatoma. The epithelial layer produces the keratin, whereas the sub-epithelial layer contains mesenchymal cells that can resorb bone and that give cholesteatoma its invasive properties.
Cholesteatoma is a destructive process. It invades the middle ear and causes damage with passive growth and active destruction of adjacent bony structures essential to hearing.

This book is useful for otolaryngologists – head and neck surgeons, residents, and fellows. They can go online to refer to the most up-to-date information on cholesteatomas and other middle-ear lesions.
It presents the three components of middle-ear surgery: the middle ear, the mastoid, and the meatus and resultant cavity. The authors provide perspectives on the controversies in cholesteatoma management like canal wall reconstruction, facial nerve monitoring, the use of endoscopes in chronic ear surgery, and postoperative care.
This is an excellent text on the rare and destructive disease of cholesteatoma, with lots of images, diagnostic methods, and detailed operative procedures.
