Lymphocytic streaming as an indicator of inner ear compartmentalization.

Despite a great deal of anatomic and physiologic data in animals, controversy still exists over whether or not the perilymphatic space in man is directly connected to the intracranial space via a patent cochlear aqueduct or other fluid channel. Human physiologic data are limited, indirect, and conflicting. Anatomic and pathologic data have heretofore been inadequate for answering the question convincingly. The temporal bones of a 19-year-old woman with central nervous system lymphoblastic leukemia are discussed. The passive-appearing movement of lymphoblasts between cerebrospinal fluid and perilymphatic spaces suggests both a functionally patent cochlear aqueduct and alternate pathways.

Survival of implanted irradiated cartilage.

As a result of our study the following conclusions may be drawn: 1. Irradiated homograft costal cartilage appears to survive as a nonviable implant in part replaced by host tissue in the cat. 2. Such replacement may be minimized by leaving as much perichondrium intact as is feasible. 3. Boiling or freezing fresh autogenous cartilage in an attempt to alter its warping characteristics is asking for increased resorption.

Topognostic and prognostic evaluation of traumatic facial nerve injuries.

If and when to intervene during the course of a traumatic facial palsy depends on the immediacy of the palsy, signs and symptoms of an associated temporal bone fracture, function of the various facial branches, and the results of electrical stimulation. Some facial nerve tests will be more valuable than others in a given case. The following is a philosophy of management that has proven useful to the author in the management of facial palsies of traumatic causes.

Intralabyrinthine acoustic neurinomas.

Two temporal bones are presented that contain acoustic neurinomas unsuspected during life and anatomically limited to the perilymphatic labyrinth. One tumor occupies the modiolus and scala tympani of the cochlea without involving the internal auditory canal. The other tumor originates in the fibers below the utricular macula and spares both the macula and the lamina cribrosa. Neither case demonstrates bone destruction. Even if these tumors had been suspected during life, tomograms would have been normal and the posterior fossa myelogram would have shown complete filling of the internal auditory canal.
