Abstract Objective To evaluate the frequency, type and indications of nasal turbinate (NT) resection during endoscopic, anterior skull base surgery and to analyze factors that may have an impact on the need of NT removal. Methods In this retrospective cohort study, 306 subjects (150 males and 156 females, mean age 55.4 ± 15.3 years) who underwent multidisciplinary, transnasal, endoscopic tumor surgery of the anterior skull base using 4-handed techniques between 2011 and 2019 at the Department of Otorhinolaryngology, Medical University of Graz, were included. Results In the majority of interventions (n = 281/306; 91.8%), all NT were preserved. Significant factors influencing the need of NT resections turned out to be type of endoscopic approach (p < 0.001; V = 0.304), sagittal (p = 0.003; d = 0.481) and transversal (p = 0.017; d = 0.533) tumor diameter, tumor type (p < 0.001; V = 0.355) and tumor location (p < 0.001; V = 0.324). Conclusions NT can be preserved in the majority of patients undergoing tumor resection in anterior, transnasal, skullbase surgery and routine resection of NT should be avoided. Variables that have an impact on the need of NT resections are types of endoscopic approaches, sagittal and transversal tumor extension and tumor type. These factors should be considered in planning of surgery and preoperative information of patients.

Anterior skull base (ASB) schwannomas are extremely rare and can often mimic other pathologies involving the ASB such as olfactory groove meningiomas, hemangiopericytomas, esthesioneuroblastomas, and other malignant ASB tumors. The mainstay of treatment for these lesions is gross-total resection. Traditionally, resection for tumors in this location is performed through a bifrontal transbasal approach that can involve some degree of brain retraction or manipulation for tumor exposure. With the recent advances in endoscopic skull base surgery, various ASB tumors can be resected successfully using an expanded endoscopic endonasal transcribriform approach through a “keyhole craniectomy” in the ventral skull base. This approach represents the most direct route to the anterior cranial base without any brain retraction. Tumor involving the paranasal sinuses, medial orbits, and cribriform plate can be readily resected. In this video atlas report, the authors demonstrate their step-by-step techniques for resection of an ASB olfactory schwannoma using a purely endoscopic endonasal transcribriform approach. They describe and illustrate the operative nuances and surgical pearls to safely and efficiently perform the approach, tumor resection, and multilayered reconstruction of the cranial base defect.

The advent and widespread development of endonasal endoscopic techniques have recently expanded the frontiers of skull base surgery. The reduced invasiveness, wider and adjustable visualization of the operative field, and lack of postoperative cosmetic defects are well-known advantages of the endonasal endoscopic approaches compared with traditional surgical exposures both in adults and in children. The need to avoid disruption of facial growth centers and permanent tooth roots represents a further special consideration in favor of these endoscopic techniques in children. The authors report on a case of solitary myofibroma involving the ethmoid, mesial orbits, and anterior skull base with intracranial intradural expansion in a 17-month-old girl. The occurrence of such proliferative disease along the skull base is exceedingly rare. The tumor was successfully excised via an endoscopy-assisted cranionasal approach in which a transcranial microsurgical exposure was combined with endonasal endoscopic access to ensure a radical resection and optimize skull base reconstruction. To the authors' knowledge, the patient in this case is the youngest reported patient in the literature who has undergone treatment with this surgical strategy. The outcome in this patient underscores the feasibility and safety of endoscopic endonasal surgery even in toddlers and early childhood.
