“…On CT, REAH is associated with a characteristic unilateral or bilateral widening of the olfactory cleft in the coronal plane 573,577,586–589 . The first report to describe this finding found that the mean olfactory cleft width was 12.1 mm in patient with REAH, compared to 5.4 mm in patients with nasal polyposis and 4.2 mm in patients without sinonasal pathology 589 .…”

“…Another comparative study found that a width of >10 mm was characteristic of REAH, with 88% sensitivity and 74% specificity 588 . Typically there is no associated bone erosion on CT 586 . On MRI, REAH is intermediate in signal intensity on T1‐ and T2‐weighted sequences, often with a cerebriform contour and homogeneous postgadolinium enhancement 576,580,590 …”

“…In cases of isolated REAH, the extent of surgery reported ranges from simple excision to subperiosteal dissection and drilling of the bone 576,577,587,591 . In cases of REAH with nasal polyposis, authors report performing standard endoscopic sinus surgery, including total ethmoidectomy 573,576,577,584,586,592–594 . Evidence‐based recommendations regarding extent of surgery for REAH cannot be made, given the limitation of existing evidence to case series.…”

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

BackgroundRespiratory epithelial adenomatoid hamartoma (REAH) is a recently classified histopathologic diagnosis often identified incidentally following endoscopic sinus surgery (ESS) for presumed chronic rhinosinusitis. Limited data exist defining preoperative imaging features and surgical outcomes. The purpose of this study is to examine characteristic imaging findings of REAH and postoperative olfactory and recurrence outcomes.MethodsA systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis (PRISMA) guidelines on articles published from 1995 to present. PubMed, EMBASE, and Ovid MEDLINE databases were queried for studies pertinent to imaging findings of REAH and surgical outcomes. Quality of articles was assessed using the Methodological Index for Non‐Randomized Studies (MINORS).ResultsA total of 294 articles were identified, with 15 meeting inclusion criteria. Seven articles assessed both imaging findings and surgical outcomes. Three articles focused exclusively on imaging, whereas 5 examined surgical outcomes. Olfactory cleft (OC) widening greater than 10 mm on computed tomography (CT) was characteristic of REAH. A total of 441 patients with REAH were included; 221 patients (50.1%) had concurrent nasal polyposis, whereas 154 patients (34.9%) had isolated REAH. Surgical intervention ranged from simple excision to complete ESS. Sixty‐five percent (65%) of patients reported improved olfaction; 4.1% of patients recurred with follow‐up ranging from 4 months to 5 years.ConclusionA widened OC may suggest the presence of REAH. This disease process has been identified in patients with nasal polyposis or encountered as an isolated lesion. Targeted surgery may result in improved olfaction and a low likelihood of recurrence, though long‐term prospective studies are necessary.
