Abstract Objective This study was aimed to compare the closure of skull base defect in endoscopic endonasal transsphenoid surgery of pituitary tumors, using bipedicled nasal septal flap versus fascial closure. The study hypothesis being that bipedicled nasal septal flap is better, compared with fascial closure of skull base defect post–endoscopic endonasal transsphenoid surgery of pituitary tumors. Methods All the eligible patients were randomly divided into two groups and then randomly allocated to the surgeons. In one group, fat and fascia lata was used for closure of the skull base defect and nasal septal flap was not harvested whereas in the other, nasal septal flap was used for closure. Result There was a statistically significant difference in postoperative cerebrospinal fluid leak between the two groups. Patients who had undergone flap repair had lower incidence of postoperative cerebrospinal fluid (CSF) leak. Duration of postoperative hospital stay was also less among the group who underwent flap repair (statistically significant). Conclusion Bipedicled nasal septal flap serves an excellent cover for the skull base defect following endoscopic endonasal transsphenoidal pituitary surgery. It can prevent postoperative CSF leak even in cases where tissue glue is not used.

Primary spontaneous cerebrospinal fluid (CSF) rhinorrhea is an unusual phenomenon that may occur anywhere along the skull base. However, CSF leaks originating from clival defects are rarely reported in the literature. The majority of reported cases were managed with microscopic techniques, using free grafts. The present study discusses a case of spontaneous CSF rhinorrhea from a clival defect closed with our transnasal operative approach using endoscopic techniques. The skull base defect was successfully managed with an endoscopic binostril approach to create a nasal septal flap pedicled at the sphenopalatine artery, while also preserving the integrity of the nasal septum.

Meningiomas are the most prevalent primary intracranial tumor, with 3%–10% arising from the tuberculum sellae. Optimal management consists of total microsurgical resection with preservation of surrounding structures. The authors present a 64-year-old woman with progressive bilateral vision loss, including visual acuity deficits and bitemporal hemianopsia. MRI revealed a 2-cm tuberculum sellae meningioma causing optic apparatus compression. An extended endoscopic endonasal transtuberculum approach was utilized for gross-total resection, including microdissection of tumor from the optic chiasm and infundibulum. Closure was performed with multilayer tensor fascia lata autograft and a pedicled nasal-septal flap. The patient’s postoperative exam showed visual improvement and normal pituitary function.The video can be found here: https://youtu.be/ZfNB_rhlyeI.

ABSTRACT Resection of the anterior clinoid process results in the creation of the clinoid space, an important surgical step in the exposure and clipping of clinoidal and supraclinoidal internal carotid artery aneurysms. Cerebrospinal fluid rhinorrhea is an undesired and potentially serious complication. Conservative measures may be unsuccesful, and there is no consensus on the most appropriate surgical treatment. Two patients with persistent transclinoidal CSF rhinorrhea after aneurysm surgery were successfully treated with a combined endoscopic transnasal/transeptal binostril approach using a fat graft and ipsilateral mucosal nasal septal flap. Anatomical considerations and details of the surgical technique employed are discussed, and a management plan is proposed.

We describe the clinical findings in two patients with pathologically diagnosed olfactory neuroblastoma (ONB) of the sinonasal area and the surgical methods used for its treatment. Using an endoscopic endonasal approach (EEA) without dura resection, along with radiotherapy, we successfully treated ONB at the Kadish stage A. One of our patients, however, experienced tumor recurrence 24 years after open surgery with radiotherapy that was conducted at another hospital. This patient was no longer eligible for radiotherapy, and the tumor was therefore resected with dura resection using an EEA combined with duraplasty. The dura resection with duraplasty using fascia lata and a pedicled nasal septal flap was minimally invasive. As with surgery without duraplasty, a postoperative computed tomography (CT) examination revealed that EEA with duraplasty led to quick improvement of the postoperative inflammatory response as well as pneumocranium. Here, we investigated whether to modify the method of surgery depending upon the primary site of early-stage ONB. We suggest that, in early-stage ONB, an endoscopic endonasal approach is an effective and less invasive method. It is also advisable to perform dura mater resection of the lesion site despite the absence of obvious intracranial invasions in image findings.

Endonasal resection of olfactory groove meningiomas allows for several advantages over transcranial routes, including a direct approach to the bilateral anterior cranial base and dura mater, early tumor devascularization, and avoidance of brain retraction. Although considered minimally invasive, the endoscopicapproach to the cribriform plate typically requires resection of the superior nasal septum, resulting in a large superior septal perforation. The septal transposition technique improves preservation of sinonasal anatomy through the elimination of a septal perforation while allowing for wide exposure to the midline anterior cranial base and harvest of a nasal septal flap. Herein, the authors describe a 39-year-old female who presented with a progressively enlarging olfactory groove meningioma. An endoscopic endonasal resection with a septal transposition technique was performed. On follow-up, the nasal cavity had completely normal anatomy with preservation of the turbinatesand nasal septum. The authors conclude that septal transposition is a useful technique that allows wide exposure of the anterior cranial base with maximal preservation of normal nasal anatomy and avoidance of a large septal perforation.
