[Cholesterol granuloma media: 8 cases report].
OBJECTIVE
To investigate the etiology, pathogenesis diagnosis and therapy of cholesterol granuloma media.


METHODS
Eight cases (9 ears) of middle ear cholesterol granuloma were retrospectively reviewed. Nine ears all have a speciality of conductive deafness with a light to middle level, blue eardrum and tympanogram all showing B type (except one case of eardrum perforation in the tension part). Seven cases (8 ears) were cured by tympanic cavity exploration opening epitympanum, tympanic antrum, mastoid cells and thoroughly eliminating granulation tissue. Grommet insertion and modified radical mastoidectomy were performed on 5 cases and 2 cases, respectively. The other one case was only carried out with eardrum puncture.


RESULTS
Seven cases (8 ears) after operation were followed up for six monthes to six years. Six cases (7 ears) were cured out without recurring; one case (1 ear) recurred. One case was not followed up.


CONCLUSIONS
Otoblennorrhea of blood without obvious reason and blue eardrum should be coupled with CT to enhance the diagnosis rate before operation. CG should be treated by operation to clean disease location, air and drainage tympanicus cavity and mastoid.
