JAMA. 1910;55(15):1270-1272. doi:10.1001/jama.1910.04330150030011
Abstract

Infections of the labyrinth from suppurative otitis media may be classified as (1) circumscribed, (2) diffuse, (a) manifest (circumscribed or diffuse), (b) latent (diffuse), (3) perilabyrinthitis.

Circumscribed labyrinthitis is qualified thus: with erosion, fistula or stapes subluxation, or without either.

Diffuse labyrinthitis is qualified as suppurative, serous or hyperemic.

By manifest labyrinthitis is meant an inflammatory disease of the labyrinth, showing characteristic spontaneous symptoms.

Latent labyrinthitis signifies a like disease, showing no characteristic manifest spontaneous symptoms.

Perilabyrinthitis is an inflammatory disease of the cellular bone surrounding the labyrinth capsule. It can cause suppurative, serous and hyperemic labyrinthitis, or necrosis with sequestration of a part or the whole of the cochlea.

This cellular bone may be either diploetic or pneumatic. When pneumatic the cells have a mucous lining and communicate with the antrum and mastoid cells. A pneumatic structure must be frequent, as Wales1 speaks of the membranous lining as
