Quantum type bone remodeling in the otic capsule of the pig.
Normal quantum type bone remodeling was studied in temporal bones of young domestic pigs by means of combined microradiography, osteofluorochrome labelling and osteoid staining. Evolving secondary osteons were morphologically normal although much less in the otic capsule than in the surrounding compacta of the temporal bones or in long bones. Moreover, remodeling was totally absent in bone tissue immediately adjacent to perilymphatic spaces suggesting the presence of a local mechanism controlling resorption and perhaps formation in the bony otic capsule.
