Nine patients with ipsilateral delayed endolymphatic hydrops were treated. All cases were initially treated by conservative therapy using isosorbide or other drugs and 4 patients have been doing well without surgical intervention, though they occasionally have slight dizziness. Five patients required surgery to control vertigo. Three patients first underwent cochleosacculotomy to maintain the vestibular function in the diseased ear, but vertigo recurred after 6 months in all 3 cases. These 3 patients and another patient who wanted definitive treatment right from the start underwent transmastoid labyrinthectomy which resulted in complete control of vertigo. One patient received chorda tympani nerve section because he did not want his vestibule destroyed. After the nerve section, he has had no vertigo though sometimes dizziness. Transmastoid labyrinthectomy seems to be the best treatment for ipsilateral delayed endolymphatic hydrops.

UI	MeSH Term	Description	Entries
D007547	Isosorbide	1,4:3,6-Dianhydro D-glucitol. Chemically inert osmotic diuretic used mainly to treat hydrocephalus; also used in glaucoma.	Dianhydrosorbitol
D007758	Ear, Inner	The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.

D002814	Chorda Tympani Nerve	A branch of the facial (7th cranial) nerve which passes through the middle ear and continues through the petrotympanic fissure. The chorda tympani nerve carries taste sensation from the anterior two-thirds of the tongue and conveys parasympathetic efferents to the salivary glands.

D003051	Cochlea	The part of the inner ear (LABYRINTH) that is concerned with hearing. It forms the anterior part of the labyrinth, as a snail-like structure that is situated almost horizontally anterior to the VESTIBULAR LABYRINTH.	Cochleas
D004234	Diuretics, Osmotic	Compounds that increase urine volume by increasing the amount of osmotically active solute in the urine. Osmotic diuretics also increase the osmolarity of plasma.	Osmotic Diuretic,Osmotic Diuretics,Diuretic, Osmotic
