Ménière’s disease is a chronic inner-ear disease attributed to endolymphatic hydrops. Magnetic resonance imaging with gadolinium allows visualisation of endolymphatic hydrops in vivo and may be an adjunct to diagnosis.

Thirty-eight patients suspected of having Ménière’s disease underwent T2 weighted three-dimensional fluid-attenuated inversion recovery and true inversion recovery sequence magnetic resonance imaging 4 hours post double-dose intra-venous gadolinium. Presence of endolymphatic hydrops was graded by two radiologists at 0 and 4 months. Correlation to clinical diagnosis was assessed using Fisher’s exact test.

Hydrops was identified in 88 per cent, 17 per cent and 27 per cent of patients with Definite Ménière’s, Probable Ménière’s and Undifferentiated disease, respectively. A significant correlation existed between diagnosis and presence of hydrops. Sensitivity and specificity were 88 per cent and 67 per cent, respectively. Intra- and inter-observer agreement for presence and grading of hydrops was near-perfect and substantial to near-perfect, respectively.

Magnetic resonance imaging demonstrates radiographic hydrops with significant correlation to clinical diagnosis and good intra- and inter-observer agreement.

Despite a lot of scientific advancements in otology, canal wall-down mastoidectomy is still considered to be the standard of care in the management of extensive cholesteatoma. To avoid large cavity related problems, mastoid obliteration has been described in the literature for many decades. Controversy prevails among otologists regarding the materials used for obliteration. This study aimed to evaluate the results of mastoid obliteration and reconstruction of posterior meatal wall after mastoidectomy using ready-to-use, self-setting hydroxyapatite bone cement.

Retrospective analysis was performed of all consecutive patients who underwent canal wall down mastoidectomies and primary mastoid obliteration with ready-to-use, self-setting hydroxyapatite bone cement. Minimum follow-up was 1 year. Primary Outcome measures include need for explantation and post-operative complications.

Total of 26 patients were included in the study. Only one patient required complete explantation. All patients acquired dry cavities in the final follow-up. Few minor complications including external auditory canal granulations and post-aural wound dehiscence. There was no cholesteatoma recidivism.

Ready-to-use, self-setting hydroxyapatite bone cement serves the purpose of mastoid obliteration. In addition, it is time efficient and requires less expertise. It has excellent outcomes in terms of cholesteatoma recidivism. We recommend further research in this area with a large cohort.
