ABSTRACT
BACKGROUND AND OBJECTIVES:
The purpose of the study was to compare the mastoid air-cell volume of the patients with superior semicircular canal dehiscence syndrome (SCDS) and that of the control patients with otosclerosis and temporal bone (TB) fracture. SUBJECTS ANDMETHODS:
Ten patients with SCDS were enrolled and 10 patients with bilateral otosclerosis and TB fracture were selected as control groups by age and sex matching. To measure the mastoid air-cell volume, 3D reconstruction software was used.RESULTS:
In 10 patients with SCDS, the mean age was 44.5 years, ranging from 16 to 79 years (M F=4 6). Mean mastoid air-cell volume in the SCDS side was 3319.9 mm3, whereas 4177.2 mm3 in the normal side (p=0.022). Mean mastoid air-cell volume in the right side of otosclerosis patients was 6594.3 mm3 and it was not different from 6380.5 mm3 in the left side (p=0.445). Mean mastoid air-cell volume in normal side of TB fracture was 6477.2 mm3. The mastoid air-cell volume in the SCDS side was significantly smaller than that of otosclerosis and TB fracture patients (p=0.009, p=0.002, respectively). The mastoid air-cell volume in the normal side of SCDS was significantly smaller than that of TB fracture (p=0.019), but not significant with that of otosclerosis (p=0.063).CONCLUSIONS:
Our findings revealed that the mastoid air-cell volume in the SCDS side was significantly smaller than control group, which suggest that the decreased mastoid pneumatization is closely related to the generation of SCDS.
