Abstract
Introduction: Pituitary adenomas have the potential to infiltrate the dura mater, skull, and the venous sinuses. Tumor extension into the cavernous sinus is often observed in pituitary adenomas and techniques and results of surgery in this region are vastly discussed in the literature. Infiltration of parasellar dura and its impact for pituitary surgery outcomes is significantly less studied but recent studies have suggested a role of endoscopic resection of the medial wall of the cavernous sinus, in selected cases. In this study, we discuss the techniques and outcomes of recently proposed techniques for selective resection of the medial wall of the cavernous sinus in endoscopic pituitary surgery.
Methods: We performed a systematic review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and protocol and a total of 4 studies with 106 patients that underwent an endoscopic approach for resection of pituitary tumors with resection of medial wall from cavernous sinus were included. Clinical and radiological data were extracted (sex, mean age, Knosp, prior surgery, tumor size and type, complication rate, and remission) and a meta-analysis using the RevMan 5.4 software was performed.
Results: A total of 5 studies with 208 patients were included in this analysis. The mean age of the study population was 48.87 years (range 25-82) with a female/male ratio of 1:1.36. Majority of the patients had Knosp Grade 1 (n = 77, 37.02%) and Grade 2 (n = 53, 25.48%). The complication rate was 4.81% (n = 33/106) and the most common complication observed was a new transient CN dysfunction and diplopia. Early disease remission was observed in 94.69% of the patients (n = 196/207). The prevalence rate of CS medial wall invasion varied from 10.4 % up to 36.7%. This invasion rate increased in frequency with higher Knosp Grade. The forest plot of persistent disease vs. remission in this surgery approach showed a p < 0.00001 and heterogeneity (I^2 = 0%).
Discussion: Techniques to achieve resection of the medial wall of the cavernous sinus via the endoscopic endonasal approach include the “anterior to posterior” technique (opening of the anterior wall of the cavernous sinus) and the “medial to lateral” technique (opening of the inferior intercavernous sinus and). Although potentially related with improved endocrinological outcomes, these are advanced surgical techniques and require extensive anatomical knowledge and extensive surgical experience. Furthermore, to avoid procedure complications, extensive study of the patient’s configuration of cavernous ICA, Doppler-guided intraoperative imaging, surgical navigation system, and blunt tip knives to dissect the ICA’s plane are recommended.
Conclusion: Endoscopic resection of the medial wall of the cavernous sinus has been associated with reports of high rates of postoperative hormonal control in functioning pituitary adenomas. However, it represents a more complex approach and requires advanced experience in endoscopic skull base surgery. Additional studies addressing case selection and studies evaluating long term results of this technique are still necessary.

PMID: 36206699 DOI: 10.1016/j.ijporl.2022.111332
Abstract
Objective: Endoscopic endonasal approaches to pediatric skull base lesions are rare, challenging, and present distinct considerations from adult pathology. In this study, we describe our endoscopic technical approach to various skull base lesions demonstrating the efficacy and nuances of these approaches in pediatric patients.
Methods: Pediatric patients underwent endoscopic approach for skull base lesions from January of 2015 to April of 2021 were included in the study. Presenting symptoms, indications for surgery, surgical outcomes, intraoperative and postoperative complications, length of hospital stay, and length of follow-up were documented.
Results: A total of 18 patients (median age 12, age-range 1-15, 53% male) underwent 19 endoscopic transsphenoidal procedures. The pathologies included craniopharyngioma (N = 5), biopsy for an unknown disease (n = 2; orbital meningioma and pituitary lymphocytic hypophysitis), pituitary adenoma (N = 2; ACTH-secreting and non-functional), Rathke’s cleft cyst (n = 2), CSF leak repairs (n = 2; post-traumatic and spontaneous meningocele), juvenile nasopharyngeal angiofibroma (n = 3, 1 patient had 2 procedures) and rhabdomyosarcoma (n = 1). GTR was achieved in 11 out of 15 procedures (73.3%). Out of 10 patients with a sellar lesion, 6 patients had intraoperative CSF leak (60%). No patients experienced post-operative CSF leak. The median follow-up for all patients was 14 months (1-36 months).
Conclusion: Anterior and middle skull base pathology in pediatric patients can be effectively operated via an endoscopic approach across a wide variety of patient ages and conditions. Minimally invasive techniques with middle turbinate and nasal septum preservation can be achieved without compromising outcomes. A wide variety of surgical repair strategies can be successfully utilized.
Keywords: Endoscopic; Middle turbinate preservation; Pediatric skull base; Transsphenoidal surgery.

PNA Spotlight: Dr. Ravi H. Gandhi
This month the PNA spotlight shines on Dr. Ravi H. Gandhi, neurosurgeon at AdventHealth Neuroscience Institute of Orlando Neurosurgery – Winter Park where he serves as Medical Director. Dr. Gandhi attended Johns Hopkins University from 1998-2001 and Saint George’s University School of Medicine from 2002-2006, His Internship, Residency, and Fellowship was at Albany Medical Center from 2006-2013. Dr. Gandhi’s profile can be seen here. He is certified by the American Board of Neurological Surgery. Dr. Gandhi answered some questions from the PNA. Here are his answers.
What inspired you to choose your career path?
In fourth grade, my grandfather passed away from a stroke. As long as I could remember my grandfather he had had process on half of his body. I thought same time I read a fictional book which included a neurosurgeon as a character. It was at that time that I knew that I could help people That might end up with the same type of suffering that my grandfather had had. As time progressed, I learned more and more about what Neurosurgeon’s did. I sought out every neurosurgeon I could you know elementary school to shadow them to pick their brains.
I never gave up on this dream throughout my school then college and then medical school. The more I learned about Neurosurgery the more I realize that I wanted to be amongst the ranks of Not just neurosurgeons but amongst the ranks of the best neurosurgeons
What is the primary focus of your work/research?
I specialize in minimally traditional and minimally invasive methods of treating complex brain and skull base diseases. I am a board-certified neurosurgeon who is fellowship trained in Cerebrovascular, Endovascular, and Skull Base Neurosurgery. My current areas of interest include traditional and minimally invasive methods of treating complex brain and skull base diseases such as Interiors skull base Tumors such as Pituitary Tumor’s, brain tumors, trigeminal
neuralgia, and acoustic neuromas (vestibular schwannomas). I also treat cerebrovascular disorders of the brain and spine including aneurysms, arteriovenous malformations(avm), and carotid and verterbral artery stenosis predominantly minimally invasively with no incision.
What do you consider to be the future of your field?
Modern neurosurgery is a relatively young field of medicine. My expectation of our field in the future is that there will be more advances in surgical technology with better tools for Visualization Which would enable more minimally invasive approaches.
There will be more advances in neuro-oncology and fewer Brain tumors will require surgery.
What should patients know about your field/what deserves more recognition/awareness?
This is a difficult question to answer because there are so many facets to Neurosurgery. Patient should recognize that there are multiple subspecialties within Neurosurgery and seeking out care from people who specialize in your specific disease helps improve the success of your treatment.
In general, many tumors that we treat Are diagnosed very late in the course as the symptoms are often not recognized. This problem is getting better as access to MRI is improving.
What would you like to convey about yourself to your patients?
I only operate on family members. That is I consider every patient as I would a family member. I am tied to the success of each outcome as I would be for a family member.
I do not consider our practice of Neurosurgery to be a business. I am lucky to be part of a group of neurosurgeons who practice expert level neurosurgery in all subspecialties of neurosurgery and treat patients with the utmost in compassion.
Why did you get involved with the PNA; what is the extent of your involvement.
I have been an PNA member since 2018 having been inspired by their mission to disseminate information helpful to the medical community, the public and to pituitary patients and their families on matters regarding early detection, symptoms, treatments, and resources available to patients with pituitary disease.
