Identification of Cellular Voids in the Human Otic Capsule. [PDF]

J Assoc Res Otolaryngol, 2021
The otic capsule consists of dense highly mineralized compact bone. Inner ear osteoprotegerin (OPG) effectively inhibits perilabyrinthine remodeling and otic capsular bone turnover is very low compared to other bone. Consequently, degenerative changes like dead osteocytes and microcracks accumulate around the inner ear.
