Association between referred pre-surgical symptoms and radiologic structures involved with Fisher’s exact test and Cramer’s V index; significant results are shown in bold.
| Pre-Surgical Symptom | Radiologic Structures Involved | Fisher’s Exact Test | Cramer’s V |
| Headache | Temporal lobe/posterior fossa compression | p = 0.04 | 0.444 |
| Meckel’s cave compression | p = 0.107 | - | |
| Fainting | Jugular tubercule erosion | p < 0.001 | 0.722 |
| Diplopia | Dorello canal compression | p = 0.001 | 0.653 |
| Otitis Media | Eustachian tube compression | p = 0.287 | - |
| Vestibular symptoms | Internal auditory canal erosion | p = 0.02 | 0.536 |
| Facial paresthesia | Meckel’s cave compression | p = 0.03 | 0.468 |
| Hearing loss | Cochlear basal turn erosion | p = 0.103 | - |
| Internal auditory canal erosion | p = 0.1 | - | |
| Tinnitus | Cochlear basal turn erosion | p < 0.001 * | 1.00 |
| Internal auditory canal erosion | p = 0.2 | - |
* only one patient of our cohort experienced tinnitus.
