Radioanatomic assessment of the geniculate ganglion dehiscence and dimension: A cadaveric study.

Abstract

OBJECTIVE

The main aim of this study placed on cadavers was to compare the data related to geniculate ganglion (GG) dehiscence and dimension obtained from computed tomography (CT) with dissection values.

METHODS

This study was conducted on 20 temporal bones obtained from 10 cadavers (4 females and 6 males) aged between 45-92 (71.50±15.98) years. All the measurements related to GG dimension were performed with a CT scanner and microdissection.

RESULTS

The size of GG including its area, length and width did not show statistical significant differences in terms of sexes, sides and assessment methods (CT and cadaveric dissections). The dehiscent GG was observed in 6 (30%) and 5 (25%) out of 20 temporal bones in CT and cadaveric dissections, respectively. The presence and absence of GG dehiscence in CT and dissection were similar in 75%.

CONCLUSIONS

Our findings based on dissection data suggested that radiological evaluation of dehiscent GG detection might be erroneous by 25%, which proved that surgeons should be careful when lifting the dura to prevent GG injury during middle cranial fossa surgical approaches. On the other hand, there was no statistical difference between CT and dissection measurements related to GG dimension.
