Nonlamellar new bone formation in the anterior attic recess.
An area of nonlamellar new bone formation was observed in the anterior epitympanic region of 27 randomly chosen human temporal bones. The donors ranged in age from 9 to 80 years and had no evidence of ear disease or systemic skeletal or metabolic abnormalities. The frequency of this finding suggests that it is a normal feather of the human anterior attic recess.
