  • Objective:

    To estimate the incidence of tympanogenic labyrinthitis ossificans.

    Methods:

    The records of patients treated with mastoidectomy for various tympanogenic aetiologies from January 2007 to December 2011 were retrospectively reviewed. Patients whose high-resolution computed tomography scans showed evidence of labyrinthine calcification of the temporal bone were enrolled. Patients with a history of head and neck cancer, meningitis, and otosclerosis, and patients with cochlear implants, were excluded from this study.

    Results:

    A total of 195 patients were enrolled in this study; 4 of the patients presented with calcification in the inner ear. Therefore, the incidence of tympanogenic labyrinthitis ossification was 2 per cent. The computed tomography findings revealed: (1) cochlear calcifications of the basal and middle turn in two patients; and (2) vestibular, superior semicircular canal, posterior semicircular canal and lateral semicircular canal calcification in one, four, three and two patients, respectively.

    Conclusion:

    The incidence of tympanogenic labyrinthitis ossification in patients who had undergone a mastoidectomy was 2 per cent.

  • Imaging for cochlear implants

  • All patients in the Birmingham Cochlear Implant Programme underwent computerized tomography (CT) scanning and were assessed and images interpreted by the main author. Of the first 100 cases, 20 were considered to have abnormalities of the inner ears by CT imaging. It is concluded that the commonest abnormality was cochlear otospongiosis followed by labyrinthitis ossificans.

    Otospongiosis is well shown by CT which gives a good predicator of luminal patency.

    However, labyrinthus obliterans, although usually apparent on CT, is not reliably shown in all cases and T2 weighted magnetic resonance imaging (MRI) is better.
