The problems of open radical mastoid cavities are well known. One of the ways to manage such problems is obliteration of the mastoid cavity. Most biological materials, such as muscle flap or bone chips/paste, tend to be resorbed with time, resulting in reformation of the cavity. The author reports a series of 34 mastoid obliteration operations using hydroxyapatite granules and an inferiorly based periosteal flap. The follow-up period was between 1 and 5 years. The obliterated cavities remained small, stable and trouble-free. Water was tolerated in the cavities allowing most patients to enjoy water sports. Only one patient had permanent discharge due to incomplete epithelialization of the obliterated cavity.

D013524	Surgical Flaps	Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.

D018424	Cholesteatoma, Middle Ear	A mass of KERATIN-producing squamous EPITHELIUM that resembles an inverted (suck-in) bag of skin in the MIDDLE EAR. It arises from the eardrum (TYMPANIC MEMBRANE) and grows into the MIDDLE EAR causing erosion of EAR OSSICLES and MASTOID that contains the INNER EAR.
