Periotic
Definition:
(a.) Surrounding, or pertaining to the region surrounding, the internal ear; as, the periotic capsule.
(n.) A periotic bone.
Example Sentences:
(1) One wall of the recess is associated with a diverticulum of the intracapsular periotic sac, and an adjacent wall is occupied by the basilar papilla.
