Labyrinthine hydrops is second from the standpoint of current interest. The material selected for review is arranged under the following heads: otosclerosis, pathologic studies and treatment; acoustic trauma and aero-otitis; hydrops of the labyrinth, and miscellaneous contributions on cause and treatment.
Pathologic Studies.—Lempert and Wolff1 made detailed microscopic studies on 100 ossicles removed at fenestration operations. The changes of vascular content noted were the formation of clear globules, accumulation of fragmented red blood cells, sludge formation, and accumulation of polymorphonuclear cells. The vascular walls revealed constriction, tortuosity, periarteritis, and endarteritis. The bone changes noted were excessive blue mantling, hypervascularity, decalcification, osteofibrosis, osteoporosis, hyperostosis with malformations, ankylosis of joints, and ischemia with empty lacunas. It was believed that the vascular changes noted lead in more or less logical and chronological
