Clival Chordoma

Chordomas of the clivus are aggressive lesions which arise from the remnants of the primitive notochord and pose unique diagnostic and management challenges. Radical resection of chordomas has been recommended for better outcomes and their surgical treatment has been challenging to neurosurgeons for many years. Transbasal, orbitozygomatic, subtemporal,transcondylar, transmaxillary, and extended transsphenoidal techniques have been proposed. We report a case of clival chordoma treated by endonasal endoscopic transsphenoidal approach.

Introduction. According to the recommendations of Russian and international professional associations, treatment of germinomas can be initiated without histological verification of the diagnosis, since it can be based on biochemical tumor markers. However, patients with brain germinomas usually have normal levels of these markers; therefore, histological verification is required. Stereotactic biopsy and transcranial biopsy are sometimes associated with a risk of damage to crucial anatomical structures. Currently, both biopsy and total removal of sellar and parasellar tumors can be performed via endoscopic endonasal approach. The study objective is to demonstrate the possibility of using endoscopic transsphenoidal approach for biopsy and total removal of chiasmosellar germinomas. Materials and methods. Thirteen patients with primary chiasmosellar germinomas underwent endoscopic endonasal interventions in N. N. Burdenko National Medical Research Center for Neurosurgery between 2010 and 2017. The “Germinoma-2008” protocol was used in the subsequent treatment of these patients. The male to female ratio was 2.25 : 1; mean age was 21.1 years (6–38 years).Results. The surgery volume varied between biopsy (n = 4) and partial (n = 5) or complete (n = 4) tumor removal. The diagnosis was histologically verified in all patients. None of the patients developed liquorrhea and / or meningitis in the postoperative period, which suggests that the surgery was effective and safe. Conclusion. The endoscopic endonasal approach for histological verification of the diagnosis and removal of chiasmosellar germinomas is safe and effective.

Object Whereas most pituitary adenomas are removable via the transsphenoidal approach, certain cases, such as dumbbell-shaped or suprasellar adenomas and recurrent and/or fibrous tumors, remain difficult to treat. The authors present their experience with the extended endoscopic endonasal approach to the suprasellar area in managing this subset of tumors, which are classically treated through a transcranial route. Methods From June 1997 to December 2008, 615 patients underwent endoscopic endonasal transsphenoidal surgery for pituitary adenomas in the Department of Neurosurgery of the Università degli Studi di Napoli Federico II. Of this group, 20 patients with pituitary adenomas needed an extended endoscopic endonasal transtuberculum/transplanum approach for tumor removal. Two surgical corridors were used during the transsphenoidal approach: 1) the conventional endosellar extraarachnoidal corridor and 2) a suprasellar transarachnoidal corridor. Results The extent of resection was gross total in 12 (60%) of the 20 patients, near total in 4 (20%), subtotal in 3 (15%), and partial in 1 (5%). Postoperative CSF leakage occurred in 1 patient. One patient experienced worsening of temporal hemianopsia. Conclusions The authors' initial results with the extended endoscopic approach to the suprasellar area for selected pituitary adenomas are promising and may justify a widening of the current classical indications for transsphenoidal surgery.

Abstract Introduction: Interest in using the extended endonasal transsphenoidal approach for management of suprasellar lesions, with either a microscopic or endoscopic technique, has increased in recent years. The most relevant benefit is that this median approach permits the exposure and removal of suprasellar lesions without the need for brain retraction. Materials and Methods: Fifteen human cadaver heads were dissected to evaluate the surgical key steps and the advantages and limitations of the extended endoscopic endonasal transplanum sphenoidale approach. We compared this with the transcranial microsurgical view of the suprasellar area as explored using the bilateral subfrontal microsurgical approach, and with the anatomy of the same region as obtained through the endoscopic endonasal route. Results: Some anatomic conditions can prevent or hinder use of the extended endonasal approach. These include a low level of sphenoid sinus pneumatization, a small sella size with small distance between the internal carotid arteries, a wide intercavernous sinus, and a thick tuberculum sellae. Compared with the subfrontal transcranial approach, the endoscopic endonasal approach offers advantages to visualizing the subchiasmatic, retrosellar, and third ventricle areas. Conclusion: The endoscopic endonasal transplanum sphenoidale technique is a straight, median approach to the midline areas around the sella that provides a multiangled, close-up view of all relevant neurovascular structures. Although a lack of adequate instrumentation makes it impossible to manage all structures that are visible with the endoscope, in selected cases, the extended endoscopic endonasal approach can be considered part of the armamentarium for surgical treatment of the suprasellar area.

OBJECTIVE Congenital transsphenoidal encephaloceles are rare malformations, and their surgical treatment remains challenging. This paper reports 3 cases of transsphenoidal encephalocele in 8- to 24-month-old infants, who presented mainly with airway obstruction, respiratory distress, and failure to thrive. METHODS The authors discuss the surgical management of these lesions via a minimally invasive endoscopic endonasal approach, as compared with the traditional transcranial and transpalatal approaches. A unique endonasal management algorithm for these lesions is outlined. The lesions were repaired with no resection of the encephalocele sac, and the cranial base defects were reconstructed with titanium mesh plates and vascular nasoseptal flaps. RESULTS Reduction of the encephalocele and reconstruction of the skull base was successfully accomplished in all 3 cases, with favorable results. CONCLUSIONS The described endonasal management algorithm for congenital transsphenoidal encephaloceles is a safe, viable alternative to traditional transcranial and transpalatal approaches, and avoids much of the morbidity associated with these open techniques.

Over the past three decades, surgical series of elderly patients treated for pituitary adenomas have been published, all of which used the microscopic transsphenoidal or transcranial approach. The objective of this study was to retrospectively analyze the surgical results of our first 25 elderly patients with non-functioning pituitary macroadenoma (NFPM) operated by the endoscopic endonasal approach (EEA). Preoperative visual loss was found in 92.8% of the cases, and 70.8% experienced visual improvement following surgery. Preoperative pituitary dysfunction was found in 69.2% of the cases and postoperative pituitary recovery occurred in 22.2% of them. Mean hospital stay was 6.7 days. The results of this study suggest that surgery remains the first line of treatment for NFPM in the elderly. Because age alone is not a barrier for surgery, patients should be selected for surgical treatment based on their symptoms and clinical condition, as defined by comorbidities.
