Complete resection of skull-based, cerebellopontine angle, or cavernous meningiomas may be difficult without significant morbidity, which needs to be judged carefully in young people. Multiple advances in neurosurgery including microsurgery, improved preoperative imaging, and intraoperative image-guided approaches have extended the neurosurgeon’s ability to resect lesions that were previously only partially resectable or unresectable. Advances in endoscopic endonasal surgery have made anterior cranial nerve base and clival tumors more resectable.137 The reported overall surgical morbidity has varied widely, reflecting differences in patient selection criteria as well as changes in surgical care.138–140

The mucocoele and sinus pathway need to be opened. In this case, it could be performed by an endoscopic endonasal approach to open the frontal recess on the right side. A Draf 2b procedure (opening the frontal sinus between the lamina papyracea/nasal bone laterally and the nasal septum medially) is most likely to give the best result. Endoscopic endonasal surgery can be considered for disease of the frontal sinus where the pathology does not extend laterally beyond a line in relation to the middle of the pupil of the eye.

With the advent of the endoscope and its early application to the management of inflammatory sinonasal conditions, surgeons identified significant advantages of endoscopic endonasal surgery over open approaches. Increasing endoscopic experience and advances in instrumentation and imaging technology have led to a natural evolution and expansion of endoscopic endonasal surgery to now commonly include the management of benign and malignant sinonasal tumours. The scope of this chapter is to provide the reader with a general overview of the approach to the endoscopic management of sinonasal tumours. Tumour specific management can be found in other chapters dedicated to the individual pathologies.

Only the study by Little et al. [28] is relevant to RQ1. They describe the results of a self-administered survey sent to otolaryngologists incorporating some endoscopic endonasal surgery (EES) in their clinical practice. The survey was conducted between September 2010 and March 2011, and 62 responses were collected on paper and online. Most responders were male (77%), right-hand dominant (89%), had been practising endoscopic surgery for 3–5 years (31%) and had not completed an endoscopic fellowship (63%). The responders had a median age of 36 years and performed a median of 150 EESs per year. Seventy-five per cent of physicians reported performing at least one ESBS per year. This is the reason why we have included this study in the final database of our systematic review. Unfortunately, the authors do not provide disaggregated data for this subgroup of respondents. The only specific information is that 74% of them found ESBS more ergonomically taxing than functional EES. The other results of the study are aggregated, and therefore also include responses by those physicians (25%) not performing ESBS.
Sinonasal cancer in Denmark 2008–2015: a population-based phase-4 cohort study from DAHANCA

The role of endoscopic endonasal surgery has expanded over the past two decades [13–16]. This minimally invasive approach has been shown to result in lower post-operative morbidity and mortality than open transcranial surgery in cases of anterior skull base-related tumours [2,17–21]. High-precision RT has also evolved over the past decades; however, the critical normal tissue adjacent to the sinonasal tumours poses a major challenge in target dose coverage [22]. Intensity-modulated RT (IMRT) outperforms older techniques by allowing shaping of the dose to the tumour target, hence reducing normal tissue radiation and its associated morbidity [23,24]. Proton therapy is also under consideration as an alternative to IMRT because its physical properties potentially enable further dose sparing to adjacent organs at risk [25]. The positive effects of proton therapy on OS and LRF have previously been reported in several studies [26–28].
The Endoscopic Transnasal Approach to Orbital Tumors: A Review
Published in Seminars in Ophthalmology, 2021

In the late 1980s, endoscopic endonasal surgery was introduced for treatment of inflammatory sinonasal disease and over the years, advances in technology have enabled improved visualization, efficacy, and safety of surgery. Recent innovations in endoscopic surgical techniques have broadened the scope of its application to include the adjacent skull base and orbital interface. As such, endoscopic endonasal surgery has played an increasing role in orbital surgery, providing enhanced direct visualization and magnification of the complex critical neurovascular and bony landmarks of the orbit, and often obviating the need for an external incision.
