    Morphometric analysis of anatomical relationships of the facial nerve for mastoid surgery
    Aslan, A; Goktan, C; Okumus, M; Tarhan, S; Unlu, H
    Surgical anatomical relationships of the facial nerve (FN) with several landmarks used in mastoid surgery were studied in temporal bone axial high resolution CT scans of 90 patients (180 ears). The shortest distances between the FN and external auditory canal (EAC), sigmoid sinus (SS), posterior fossa dural plate (PFD), and joint of the bony EAC with the lateral surface of the mastoid (M) were measured. These measurements were also analysed in respect of pneumatization and side differences. On average, it was found that FN-EAC was 2.9 mm, FN-SS was 10.5 mm, FN-PFD was 7.3 mm and FN-M was 15.3 mm. FN-EAC was found to be longer in poorly pneumatized bones whereas other distances were longer in pneumatized bones. FN-M was found to be longer on the right side.

    The evaluation of eustachian tube function in patients with chronic otitis media
    Yuceturk, AV; Unlu, HH; Okumus, M; Yildiz, T; Filiz, U
    In this study we evaluated eustachian tube function in patients with chronic otitis media and compared the results with normal subjects. Two different eustachian tube function tests were applied to 60 ears of the chronic otitis media group and 146 ears of the control group. While eustachian tube dysfunction was observed in 71.7% of the chronic suppurative otitis media group, it was only seen in 34.9% of the control group.
