Percutaneous computer tomography-guided technique to close postsurgical cerebrospinal fluid fistulas of the frontal sinus.
No full textBACKGROUND: The occurrence of cerebrospinal fluid fistulas of the frontal sinus after anterior skull base surgery is not rare. The extracerebral techniques to repair cerebrospinal fluid fistulas are often used, especially because they avoid open-air surgical operations. METHODS: A percutaneous CT-guided technique to close postsurgical cerebrospinal fluid fistulas of the frontal sinus in three patients after anterior skull base surgery is presented in this report. Ten millimeters of human fibrin glue was injected into the frontal sinus through one of the burr holes of the bone flap by an 18-gauge spinal needle. RESULTS: After an average follow-up period of 2.8 years, all three patients are in excellent general and neurological conditions and have not shown any further signs of rhinoliquorrhea. CONCLUSIONS: The presented percutaneous CT-guided technique can be considered a valid and harmless solution to closer small or moderate cerebrospinal fluid fistula that occurred after anterior skull base surgery
Lateral transmaxillosphenoidal approach to the lateral compartment of the cavernous sinus: technical case report
No full textThis article outlines the surgical technique and the indications for the lateral transmaxillosphenoidal approach, which is illustrated by an index case. A 27-year-old woman presented with a trigeminal sensory deficit caused by a dermoid tumor occupying the lateral compartment of her right cavernous sinus. A lateral transmaxillosphenoidal approach was performed, and the tumor was removed lateral to the intracavernous carotid artery (ICA) and medial to intracavernous cranial nerves. The lateral transmaxillosphenoidal approach is similar to the transmaxillosphenoidal approach used for the removal of pituitary adenomas invading the medial compartment of the cavernous sinus. By opening the lateral wall of the sphenoid sinus just above and laterally to the carotid artery, tumor can be removed medial to the intracavernous cranial nerves and lateral to the ICA
