メニエール病に合併せる循環障害

抄録

We studied 119 patients with Meniere's disease treated at Osaka City University Dapartment of Otorhinolaryngolgy in the three years from January 1977 to December 1979 with respect to attack conditions, laboratory data and vertigo progress.
Schellong's test results for 49 meniére's disease cases whose progress could be observed over 3 months and 26 vertigo patients that were used as controls.
1) Five types of attacks of vertigo and dizziness, B. P (blood pressure), E.T.T(eye tracking test) and O.K. P (optokinetic pattern test)-abnormalities:
In Type I, typical attacks (rotary) occured and symptoms completely disappeared after control of the attacks. Included in this type were 6 normotensive and 13 patients with BP abnormality only.
Type II resembled type I but featured mild relapse of attacks. This type included 5 patients with BP-abnormality only and, like Type I, no ETT-or OKP- abnomality.
In Type III floating sensation persisted for lorg periods after the end of typical vertigo attacks, 9 were with BP-abnormality only, 2 with BP-abnor-mality plus ETT-or OKP-abnormalities, and 4 with BP-, ETT-and OKP-abnormalities.
In Type IV floting senstion lasted for long periods after attacks and then rotary vertigo attacks reappeared, after which another floating sensation developed. Observed in this type were 3 patients with BP-abnormality only, 3 with BP-abnormality plus ETT-or O.K.P-abnormality, and 2 with BP, ETT and O.K.P abnormalities.
Type V with mild relapse of sttacks, was similar to Type IV and was seen in 2 patients with BP-abnormality only.
From the above, BP-abnormality may be considered to be a predisposition of Meniére's disease when it is the only abnormality involved, while complication of cerebrocirculatory insufficiency disease may be considered probable when ETT or OKP-abnormality is added to BP-abnormality.
2) The progress of vertigo, dizziness and Schellong's test for further in vestigation:
When only BP abnormality existed in Meniere's disease, both vertigo progress and BP-abnormality improvement went well in many patients.
However, in cases where Meniere's disease was supposed to be complicated by cerebrocirculatory insufficiency, floating sensation lasted for long periods after vertigo and BP-abnormality tended to remain unimproved. All the above show that even in Meniere's disease about 20 per cent of the patients had better be-considered.
Concomitant cerebrociulatory insuffiency should be treated accordingly.
