Surgical Procedure
The mastoid bowl (created as a result of previous destructive mastoid surgery) is obliterated by taking bone from behind and above the ear and processing it with antibiotic solution to make a paste-like material. The cavity is sculpted into normal form with the material. The process causes the body to heal the area as if there has been a fracture and reconstruction is accomplished. A new eardrum is frequently needed to maximize results. The first stage surgery is allowed to heal for 6-8 months before middle ear reconstruction is performed which is successful at restoring hearing to functional range in 65% of patients.
Miscellaneous
The procedure for mastoid obliteration was described by physicians of CEI and offers reconstructive options for patients previously without them.
