Is petrous bone pneumatization a risk factor for cerebrospinal fluid fistula following vestibular schwannoma surgery?
The higher incidence of CSF fistulas in men compared with women can be explained by means of differently pneumatized petrous bones. A high amount of petrous bone pneumatization has to be considered as a risk factor for the development of postoperative CSF fistula after vestibular schwannoma surgery.
Compared to men diagnosed with PCa managed by surgery, we observed an increased risk of RCa in patients treated with radiation therapy. Further studies are needed to validate these findings and assess whether routine colonoscopic surveillance is warranted after pelvic radiation.
