management of Sphenoid sinus cerebrospinal fluid rhinorrhea making use of an extended approach to the Sphenoid sinus
Otolaryngology-Head and Neck Surgery, 2002Co-Authors: Neelesh H Mehendale, Bradley F. Marple, Brian NussenbaumAbstract:Abstract Objectives: Specific information addressing the management of cerebrospinal fluid (CSF) fistulas that originate from within the Sphenoid sinus remains scant. The objective of this study was to review the cause and management of CSF rhinorrhea arising from the Sphenoid sinus. Study Design and Setting: This is a retrospective chart review of 12 cases of CSF rhinorrhea arising from the Sphenoid sinus that occurred in 11 patients. All patients were treated at a single institution between 1994 and 1999. Results: All patients were managed surgically with Sphenoid sinus fat obliteration using an endoscopic sublabial, transseptal approach. This approach was successful for all 12 cases, with median duration of follow-up of 18 months. Conclusions: Endoscopically assisted transseptal repair of CSF fistulas that originate within the Sphenoid sinus offers an alternate approach to previously described methods of repair in this region. Advantages include wide access to the entire Sphenoid sinus, improved access to laterally pneumatized regions within the Sphenoid sinus, and rostral mucosal closure over the repair within the sinus.

a retrospective analysis of spontaneous Sphenoid sinus fistula mr and ct findings
American Journal of Neuroradiology, 2000Co-Authors: Prashant G Shetty, Manu M Shroff, Girish M Fatterpekar, Dushyant V Sahani, Milind V KirtaneAbstract:BACKGROUND AND PURPOSE: The Sphenoid sinus is rarely implicated as a site of spontaneous CSF fistula. We undertook this study to evaluate the potential etiopathogenesis of spontaneous CSF fistula involving the Sphenoid sinus and to review the imaging findings. METHODS: We retrospectively reviewed the imaging findings of 145 cases of CSF fistula from our departmental archives (August 1995 through August 1998). Fifteen (10%) patients had CSF fistulas involving the Sphenoid sinus. Eleven (7%) patients had spontaneous CSF fistulas, whereas in four patients, the CSF fistulas in the Sphenoid sinus were related to trauma. Of the 11 patients, nine underwent only plain high-resolution CT and MR cisternography. One patient additionally underwent contrast-enhanced CT cisternography, and one other patient underwent MR cisternography only. For each patient, the CSF fistula site was surgically confirmed. The MR imaging technique included T1-weighted and fast spin-echo T2-weighted 3-mm-thick coronal sequences obtained with the patient in the supine position. The plain high-resolution CT study included 3-mm-thick, and sometimes 1- to 1.5-mm-thick, coronal sections obtained with the patient in the prone position. Similar sections were obtained after injecting nonionic contrast material intrathecally via lumbar puncture for the CT cisternographic study. We evaluated each of the 11 patients for the exact site of CSF leak in the Sphenoid sinus. We also determined the presence of pneumatization of lateral recess of the Sphenoid sinus, orientation of the lateral wall of the Sphenoid sinus, presence of arachnoid pits, presence of brain tissue herniation, and presence of empty sella in each of these patients. RESULTS: The exact sites of the CSF fistulas were documented for all 11 patients by using plain high-resolution CT, MR cisternography, or CT cisternography. In nine (82%) patients, the sites of the CSF fistulas were at the junction of the anterior portion of the lateral wall of the Sphenoid sinus and the floor of the middle cranial fossa. In the remaining two (18%) patients, the sites of the CSF fistulas were along the midportion of the lateral wall of the Sphenoid sinus. Of these 11 patients, one had bilateral sites of the CSF fistula at the junction of the anterior portion of the lateral wall of the Sphenoid sinus with the floor of the middle cranial fossa. In nine (82%) patients, the presence of brain tissue herniation was revealed, and this finding was best shown by MR cisternography. Ten (91%) patients had extensive pneumatization of the lateral recess of the Sphenoid sinus, with an equal number having outward concave orientation of the inferior portion of the lateral wall of the Sphenoid sinus. In seven (63%) patients, the presence of arachnoid pits, predominantly along the anteromedial aspect of the middle cranial fossa, was shown. In seven (63%) patients, empty sella was shown. For comparison, we reviewed the CT studies of the paranasal sinuses in 100 age-matched control subjects from a normal population. Twenty-three had extensive lateral pneumatization of the Sphenoid sinus along with outward concavity of the inferior portion of the lateral wall. None of these 23 patients had arachnoid pits. CONCLUSION: The Sphenoid sinus, when implicated as a site of spontaneous CSF leak, yields a multitude of imaging findings. These are extensive pneumatization of the lateral recess of the Sphenoid sinus, outward concave orientation of the inferior portion of the lateral wall of the Sphenoid sinus, arachnoid pits, and empty sella. Considering the normative data, we speculate that this constellation of findings could play a role in the etiopathogenesis of spontaneous Sphenoid sinus fistulas. Our findings also show the efficacy of noninvasive imaging techniques, such as plain high-resolution CT and MR cisternography, in the evaluation of Sphenoid sinus CSF leak. Our data also suggest that spontaneous Sphenoid sinus CSF leak is not an uncommon occurrence.

the unusual presentation of a myxoma within the Sphenoid sinus case report and review of the literature
World Neurosurgery, 2017Co-Authors: Julian V Clarke, Aditi H Mandpe, Peter B Weber, Hannes Vogel, Lewis Z LengAbstract:Background We describe a rare case of a Sphenoid sinus myxoma that was resected via an endoscopic endonasal skull base approach. We review the literature regarding these rare tumors of the paranasal sinuses. Case Description A 72-year-old woman was diagnosed with an incidental Sphenoid sinus tumor and left Sphenoid wing meningioma during a workup for left-sided proptosis and diplopia. Biopsies of the Sphenoid wing and Sphenoid sinus tumors were obtained. After undergoing surgical resection of the meningioma, the patient then underwent definitive resection of the Sphenoid sinus myxoma via endoscopic endonasal skull base approach. Postoperative imaging demonstrated a gross total resection. The patient suffered postoperative thromboembolic complications due to underlying hypercoagulable state but made a complete recovery and returned to her neurologic baseline. There has been no evidence of recurrent myxoma in the Sphenoid sinus 24 months after surgery. Discussion Myxomas are benign tumors derived from primitive mesenchyme. Myxomas very rarely present in the paranasal or skull base location. Complete surgical resection is the primary treatment for these tumors. The endoscopic endonasal approach is an effective technique for resecting various benign and more aggressive extradural skull base tumors. Conclusions Myxomas of the Sphenoid sinus are rare. The endoscopic endonasal skull base approach is an effective and minimal access technique for resection of this rare tumor of the Sphenoid sinus.
