“…23 Moreover, zone 1 also constitutes a surgical corridor for management of lesions extending from nasal cavity into the anterior aspect of the ITF via pterygopalatine fossa (eg, angiofibroma). 24 Zone 2, or superior interpterygoid space, correlates intimately with foramen ovale, V 3 , and the superior head of lateral pterygoid muscle. Theoretically, this zone should be a relatively common site of origin for neural tumors such as schwannoma.…”

Background: The infratemporal fossa (ITF) represents an area densely packed with neurovascular structures within irregular boundaries. The goal of this study was to classify the ITF into zones corresponding to its anatomical spaces and the order in which they are encountered during an endonasal approach (anteroposterior axis). Methods: Six cadaveric specimens (12 sides) with injected colored latex were dissected. Following an endoscopic medial maxillectomy and Denker's approach, a progressive exploration of the masticator space and upper parapharyngeal space was completed. A classification of the ITF based on welldefined spaces was ascertained. Results: The ITF was divided into five zones:• Zone 1 (retromaxillary space)-space lying between the posterolateral wall of the maxillary sinus and the temporalis and pterygoid muscles. • Zone 2 (superior interpterygoid space)-area including the superior head of the lateral pterygoid muscle, V 3 , and foramen ovale. • Zone 3 (inferior interpterygoid space)-includes the inferior head of lateral pterygoid muscle, medial pterygoid, and temporalis muscles, and the space enclosed by these muscles. • Zone 4 (temporo-masseteric space)-space lateral to the temporalis muscle (comprising fat mostly). • Zone 5 (tubopharyngeal space)-includes the Eustachian tube, tensor, and levator veli palatini muscles, and structures in upper parapharyngeal space. Conclusion: The ITF can be visualized as five zones based on spaces enclosed by the masticator muscles and upper parapharyngeal structures. This novel classification system is useful to guide endoscopic approaches to the ITF, while decreasing the potential for injury of neurovascular structures and pterygoid muscles. K E Y W O R D S endoscopic Denker's approach, infratemporal fossa, muscles of mastication, pterygoid muscle, transpterygoid Lifeng Li and Nyall R. London Jr. contributed equally to this work.

BackgroundSinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represents a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology‐based topics spanning the field.MethodsIn accordance with prior ICAR documents, ICSNT assigned each topic as an Evidence‐Based Review with Recommendations, Evidence‐Based Review, and Literature Review based on level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses format, and completed sections underwent a thorough and iterative consensus‐building process. The final document underwent rigorous synthesis and review prior to publication.ResultsThe ICNST document consists of 4 major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology‐based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention.ConclusionAs an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.This article is protected by copyright. All rights reserved

“…5,6 Inverted papilloma, nasopharyngeal angiofibroma, pleomorphic adenoma, trigeminal schwannoma, adenoid cystic carcinoma, and squamous cell carcinoma are among the most common lesions originating or extending into the pterygopalatine fossa and the infratemporal fossa. [7][8][9][10][11] From an endonasal perspective, the pterygopalatine fossa and infratemporal fossa are concealed by the posterior and lateral nasal walls of the maxillary sinus. 5,9 An endoscopic Denker's approach, which implies resection of the nasomaxillary buttress including the nasolacrimal duct and the lateral nasal wall, has been adopted to afford an adequate surgical exposure.…”

Background Both the endoscopic transnasal Denker’s and prelacrimal approaches provide surgical access to the pterygopalatine fossa (PPF) and infratemporal fossa (ITF). Objectives This study compares the potential maximum exposure of the PPF and ITF and quantifies the difference in surgical freedom via endoscopic Denker’s and prelacrimal approaches. Methods Six cadaveric specimens (12 sides) were dissected using a prelacrimal approach on one side and an endoscopic Denker’s approach on the contralateral side. The contents of the PPF and ITF were sequentially exposed. Surgical freedom for each corridor was subsequently calculated. Results This study confirms that both the prelacrimal and Denker’s approaches provide adequate exposure of the PPF and ITF. The maximum exposure boundaries were similar for both approaches, including the middle cranial fossa superiorly, floor of the maxillary sinus inferiorly, zygomatic arch and temporomandibular joint laterally, and post-styloid space posteriorly. However, the data revealed a statistically significant difference ( p < 0.05) regarding the surgical freedom of the prelacrimal (388.17 ± 32.86 mm2) and the endoscopic Denker’s approaches (906.35 ± 38.38 mm2). Conclusion When compared with an endoscopic Denker’s approach, a prelacrimal approach seems to achieve a similar extent of exposure (ie, visualization) of the PPF and ITF. Nonetheless, the endoscopic Denker’s approach offers superior surgical freedom; thus, it is preferred for the management of complex lesions which requires increased instrument maneuverability with a 3- or 4-handed technique.
