Abstract
Endoscopic skull base surgery has become an integral part of the present neurosurgical armamentarium. The pioneering efforts in which the purely endoscopic transsphenoidal approach was introduced have triggered a growing tide of using the endoscopic endonasal procedures for a large variety of skull base lesions. Because of their anatomical peculiarities, lesions of the sellar and parasellar regions lend themselves very well to the endoscopic endonasal approaches. Apart from the common pathological entities, many other less frequent pathologies are encountered in the sellar and parasellar area. In this chapter, we review the surgical technique of the endoscopic endonasal transsphenoidal approach and its extensions applied to a variety of rare and uncommon pathological entities involving the sella turcica and clivus. An overview of these pathological entities is also presented and exemplified.

Retro-Odontoid Pseudotumor Formation in the Context of Various Acquired and Congenital Pathologies of the Craniovertebral Junction and Surgical Techniques. Neurospine 2020; 18:67-78. [PMID: 33211944 PMCID: PMC8021814 DOI: 10.14245/ns.2040402.201] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Accepted: 08/24/2020] [Indexed: 12/03/2022] Open
Abstract
Retro-odontoid pseudotumor formation consists of an abnormal growth of granulation tissue typically posterior to the odontoid process, resulting as a manifestation of atlantoaxial instability. This instability can occur as a result of conditions ranging from severe mechanical trauma to metabolic disease or autoimmune conditions such as rheumatoid arthritis. A pseudotumor may impinge on the spinal nerves or even the spinal cord and brainstem, manifesting symptoms from severe neck pain to cervicomedullary compression or myelopathy, and in some cases even sudden death. The objective of this review is to consolidate the findings in published case reports and relevant prior literature reviews regarding the formation of retro-odontoid pseudotumor. We address the pathophysiology involved in acquired and congenital pseudotumor formation, including those associated with rheumatoid arthritis (panni). Additionally, we discuss past and current operative techniques designed to curtail and ultimately regress a retro-odontoid pseudotumor and pannus. Surgical techniques that are addressed include ventral decompression (both transoral and transnasal), dorsal decompression, and indications for posterior instrumentation in pannus formation, particularly in cases that may be sufficiently treated in lieu of an anterior approach. Finally, we will examine the role of external orthoses as both a method of conservative treatment as well as a potential adjunct to the aforementioned surgical procedures.

Abstract
Abstract
BACKGROUND
The vascularized nasoseptal flap (NSF) is a pillar of contemporary endoscopic skull base reconstruction. The pedicle for the NSF is supplied by the posterior septal branch of the sphenopalatine artery, which courses along the arch of the choana and sphenoid rostrum before entering the nasal septum. Resection or mobilization of this region is necessary for surgical access to the clivus.
OBJECTIVE
To describe a technique for preserving bilateral NSF pedicles during endoscopic endonasal resection of the clivus, thereby safeguarding availability of the flaps for future skull base repair needs.
METHODS
Report of operative technique with video demonstration.
RESULTS
This technique for NSF preservation allows for wide access to the clivus while saving the future option for vascularized flap repairs of skull base defects. The patient in whom we demonstrate this technique underwent complete resection of her clivus without cerebrospinal fluid leak and with preservation of both NSF pedicles.
CONCLUSION
The “rescue strip” technique for endonasal endoscopic clival surgery preserves the bilateral NSF pedicles for future use without compromising surgical access to the clivus.

Abstract
Surgical management of clival lesions presents numerous therapeutic challenges because of the close proximity of surrounding critical structures. With a detailed understanding of the endoscopic endonasal approach and relevant considerations, appropriate lesions can be removed in a safe and minimally invasive manner. Use of this technique as a primary approach represents the standard of care for many lesions at leading skull base centers, although adjunct techniques may be necessary in extensive lesions and those with significant lateral extension.

Double nasoseptal flap technique for endonasal pituitary surgery. Eur Arch Otorhinolaryngol 2016; 274:897-900.

Abstract
Endoscopic endonasal approach has been successfully used for the management of pituitary tumors; however, the loss of septal mucosa especially around sphenoethmoidal recess and posterior nasal septum might be a disadvantage of this technique. The aim of this study is to describe a variation of the endonasal approach, "double nasoseptal flap" technique in endoscopic transsphenoidal pituitary surgery, and to evaluate its outcomes. The technique depends on fully harvested bigger nasoseptal flap on one side and smaller on the other. Thirty patients were included. Functional results were assessed by preoperative and postoperative first month visual analogue scale (VAS), and morphology was evaluated by achieving intact septum from the sphenoid ostium to the columella. Sphenoid sinusitis, the presence of synechia and crusting in the sphenoethmoidal recess was also assessed. Mean VAS was 71 and 67 mm preoperatively and postoperatively, respectively (p > 0.01). There were no septal perforations, synechia, and sphenoid sinusitis postoperatively. Three patients had (10 %) crusts on sphenoethmoidal recess on first month postoperatively. Double nasoseptal flap technique has advantages, such as wider exposure during surgery; prepared flaps could be used if needed, better morphological and functional outcomes postoperatively. The technique is safe without any perforations and minimal crusting.
