title: [Restoration of external auditory canal by filling mastoid cavity with carbon pellet].
abstract: To prevent infection of an open mastoid cavity after mastoidectomy and improve hearing, the external auditory canal had been maintained on 72 cases (73 ears) by filling mastoid cavity with carbon pellet. The average duration of dry ear after operation was 25 days with a dry ear rate being 98.6%. No phenomenon of rejection and falling out appeared within 1-7 years follow-up. Carbon pellet has advantages of chemical stability, nontoxicity, good histocompatability, anti-fatigue characteristic in body fluid, and anti-corrosive effect against acid, base and salt.
