Cerebrospinal fluid (CSF) rhinorrhea after acoustic neuroma surgery is a well-known complication. CT cisternography can be used to demonstrate the entry of CSF from cerebellopontine angle cistern into the mastoid air cells, middle ear and then into nasopharynx via Eustachian tube. We report a case of paradoxical CSF rhinorrhea after surgery for acoustic neuroma in which the path of CSF leak was accurately demonstrated using CT cisternography.

Abstract Objective: Meticulous sealing of opened air cells in the petrous bone is necessary for the prevention of cerebrospinal fluid (CSF) fistulae after vestibular schwannoma surgery. We performed a retrospective analysis to determine whether muscle or fat tissue is superior for this purpose. Methods: Between January 2001 and December 2006, 420 patients underwent retrosigmoidal microsurgical removal by a standardized procedure. The opened air cells at the inner auditory canal and the mastoid bone were sealed with muscle in 283 patients and with fat tissue in 137 patients. Analysis was performed regarding the incidence of postoperative CSF fistulae and correlation with the patient's sex and tumor grade. Results: The rate of postoperative CSF leak after application of fat tissue was lower (2.2%) than after use of muscle (5.7%). Women had less postoperative CSF leakage (3.4%) than men (5.6%). There was an inverse correlation with tumor grade. Patients with smaller tumors seemed to have a higher rate of CSF leakage than those with large tumors without hydrocephalus. Only large tumors with severe dislocation of the brainstem causing hydrocephalus showed a higher incidence of CSF leaks. Conclusion: Fat implantation is superior to muscle implantation for the prevention of CSF leakage after vestibular schwannoma surgery and should, therefore, be used for the sealing of opened air cells in cranial base surgery.

AbstractTransethmoidal encephalocele is a rare condition in adult patients. It is usually diagnosed during childhood by cerebrospinal fluid (CSF) rhinorrhea, meningitis, a nasal mass, or seizures. We present a case of an adult woman with CSF rhinorrhea following resection of an occipital meningioma. The cribriform plate defect containing the encephalocele was diagnosed by computed tomography and magnetic resonance imaging. Transcranial surgery using a patch was performed successfully. We also discuss the possible pathophysiologic mechanisms of encephalocele and treatment options.

✓ The authors describe a method of preventing cerebrospinal fluid (CSF) rhinorrhea following surgery for acoustic neurinoma. Mastoid air cells exposed during craniectomy are skeletonized and packed with bone dust, then covered with Surgicel soaked with Tisseel fibrin glue. The use of this technique has reduced the number of acoustic neurinoma cases requiring secondary mastoidectomy for CSF leakage from 16% to 5%.

AbstractTension pneumocephalus (TPC) is a neurosurgical emergency that occurs when there is an expansion of trapped intracranial gas causing raised intracranial pressure. Rarely, posttraumatic TPC can occur even after 72 hours although the initial scans are normal. There are less than 20 cases of delayed TPC in the reported literature. Here, we report a case of delayed TPC that occurred 7 days after the initial injury and presented as sudden neurological deterioration. It was promptly diagnosed with a computed tomography brain and appropriate surgical intervention was performed and the outcome was good. We also did a literature review of reported cases of delayed TPC and looked out for factors that may predict its occurrence. The occurrence of an episode of cerebrospinal fluid rhinorrhea, followed by worsening of headache and sensorium in a patient with anterior cranial fossa fracture should alert a neurosurgeon to the possibility of delayed TPC.

Object Cerebrospinal fluid (CSF) rhinorrhea remains a significant cause of morbidity after resection of vestibular schwannomas (VSs), with rates of rhinorrhea after this procedure reported to range between 0 and 27%. The authors investigated whether reconstruction of the drilled posterior wall of the porus acusticus with hydroxyapatite cement (HAC) would decrease the incidence of postoperative CSF rhinorrhea. Methods A prospective observational study of 130 consecutive patients who underwent surgery for reconstruction of the posterior wall of the drilled porus acusticus with HAC was conducted between October 2002 and September 2005. All patients underwent a retrosigmoid transmeatal approach for VS resection and were followed up to document cases of CSF rhinorrhea, incisional CSF leak, meningitis, or rhinorrhea-associated meningitis. A cohort of 150 patients with VSs who were treated with the same surgical approach but without HAC reconstruction served as a control group. Results The authors found that HAC reconstruction of the porus acusticus wall significantly reduced the rate of postoperative CSF rhinorrhea in their patients. In the patients treated with HAC, rhinorrhea developed in only three patients (2.3%) compared with 18 patients (12%) in the control group. This was a statistically significant finding (p = 0.002, odds ratio = 5.8). Conclusions The use of HAC in the reconstruction of the drilled posterior wall of the porus acusticus, occluding exposed air cells, greatly reduces the risk of CSF rhinorrhea.
