“…As high resolution CT has been recommended for the evaluation of temporal bone problems, we were rather in terested in its ability to visualize the VA in general. In particular we wanted to find out whether we could confirm the hypoplastic changes and hypopneumatization of the retrolabyrinthine space, reported by other au thors [7,15]. Whereas in Stahle and Wilbrand' s [6] review 82.6% of 69 diseased ears in 63 Meniere patients showed a complete absence of air cells (sclerotic temporal bones), we were able to confirm this observa tion in all of our 10 patients.…”

“…The symmetry of pathologic radiological findings on the one side and the simulta neous, predominantly normal pneumatization of the temporal bone on the other side raise the question whether labyrinthine hypo plasia may be a constitutional anomaly, per haps predisposing certain subjects to develop Meniere's disease. Although otitis media in childhood and subsequent (focal) perilabyrinthine hypopneumatization may occur, there does not seem to exist a higher inci dence of otitis media in Meniere patients as compared to normals [15].…”

“…In the current literature on Meniere's dis ease quite a number of publications [2,[5][6][7][8]15] report that the radiological structure of temporal bones in Meniere patients differs from normals. Besides somewhat smaller volumes of the mastoid air cell systems, a characteristic decrease in the periaqueductal pneumatization and subsequently shorter aqueducts have been found by Stahle and Wilbrand [6] in a large series of patients.…”

Symptoms in Ménière’s disease are explained by hydrops of the endolymphatic system with recurrent ruptures of the membranous labyrinth. The primary cause of the increased endolymphatic volume appears to be an imbalance between secretion and resorption of endolymph which may be due to an obstruction of the endolymphatic duct and sac, located in the vestibular aqueduct (VA). Non-visualization or narrowing of the latter have been demonstrated by conventional tomography. Also, sclerosis and hypoplasia of the retrolabyrinthine portions of the temporal bone have been documented. By high resolution computed tomography (CT) we prospectively tried to demonstrate morphological alterations in 10 patients with Ménière’s disease. These were compared with a group of 14 non-Ménière patients. Visualization of the VA as well as perilabyrinthine pneumatization were assessed and the width of the retrolabyrinthine part of the temporal bone was measured. Whereas there was a slight difference in the average retrolabyrinthine width (3.8 mm in Ménière versus 5.8 in non-Ménière cases) and degree of pneumatization, there was a distinctly decreased visualization of the VA in the Ménière group. As findings were always bilateral and only 3 of 20 temporal bones showed peripheral hypopneumatization, possibly due to chronic otitis mediathe theory of a predisposing constitutional abnormality must be taken into consideration. However, we were not able to confirm a statistically proven usefulness of the CT technique in identifying an anatomical abnormality which is directly in correlation with the side of the lesion in cases of unilateral Ménière’s disease.

“…Since there is no radiographic technique available for evaluating the perilabyrinthine pneumatization metrically, it has been found convenient to classify it simply into three groups (20,21,28): 1) well developed, large-cell pneumatization, 2) limited, small-cell pneumatization, 3) absent pneumatization.…”

In an investigation of 94 plastic casts of temporal bone specimens a wide range of variations both in the generaloutline of the pyramid and in the anatomy of its specific structures was found. Attempts were made to estimate the transverse and vertical dimensions of the petrous bone. Both the mastoid and the perilabyrinthine pneumatization correlated to the dimensions of some structures, but not to the size and shape of the semicircular canals.
