“…ARS appears to be related to several anatomical anomalies: concha bullosa, infraorbital ethmoid cells greater than 3 mm in size, 97 accessory ostia in the common drainage pathway, 98 and stenosis of the infundibulum. 16 Non-OMC-related causes of ARS include oroantral fistula and dental infections. One retrospective case series showed that a periapical abscess of a maxillary tooth has a 9.75 odds ratio (p < 0.001) of causing substantial reactive mucosal thickening on cone beam CT. 110 Additionally, another study showed that periodontal disease with tooth roots emerging into the antrum and oroantral fistulas can cause the symptoms and signs of ARS.…”

“…Anatomic variations that may contribute to the pathophysiology of CRSsNP (ostensibly by narrowing sinus ostia) are generally divided into those that affect the OMC or those that affect frontal sinus drainage, although both pathways may be affected. 16,99,101,102,108,[453][454][455][456][457][458][459] Examples of OMC variations include concha bullosae, paradoxical curvature of the MT, infraorbital ethmoid (Haller) cells, and NSD. Frontal sinus drainage obstruction may be caused by Type 1-4 frontal sinus cells, supraorbital cells, suprabullar cells, frontal bullar cells, and intersinus septal cells.…”

Background:The body of knowledge regarding rhinosinusitis (RS) continues to expand, with rapid growth in number of publications, yet substantial variability in the quality of those presentations. In an effort to both consolidate and critically appraise this information, rhinologic experts from around the world have produced the International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR:RS). Methods:Evidence-based reviews with recommendations (EBRRs) were developed for scores of topics, using previously reported methodology. Where existing evidence was insufficient for an EBRR, an evidence-based review (EBR) was produced. The sections were then synthesized and the entire manuscript was then reviewed by all authors for consensus. Results:The resulting ICAR:RS document addresses multiple topics in RS, including acute RS (ARS), chronic RS (CRS) with and without nasal polyps (CRSwNP and CRSsNP), recurrent acute RS (RARS), acute exacerbation of CRS (AE-CRS), and pediatric RS. Conclusion:As a critical review of the RS literature, ICAR:RS provides a thorough review of pathophysiology and evidence-based recommendations for medical and surgical treatment. It also demonstrates the significant gaps in our understanding of the pathophysiology and optimal management of RS. Too o en the foundation upon which these recommendations are based is comprised of lowerlevel evidence. It is our hope that this summary of the evidence in RS will point out where additional research efforts may be directed. C 2016 ARS-AAOA, LLC.

“…Recent studies have demonstrated that patients with RCMs had a higher Lund-Mackay radiological score for chronic rhinosinusitis than patients without cysts (2,12). It is generally believed that OMCO, accessory ostia, AMT, and NSD can lead to complaints or symptoms via chronic paranasal sinus inflammation (13)(14)(15)(16). Therefore, recurrent mucosal inflammation is a putative risk factor for the development of RCMs.…”

Objective: The risk factors for the development of retention cysts of the maxillary sinuses (RCMs) are not clear, although RCMs are common findings on radiographic images. This study was conducted to evaluate the correlation between RCMs and other nasal-paranasal anomalies and to demonstrate the possible effects of these anomalies on the development of RCMs. Methods: In the study, paranasal sinus computerized tomography (PNsCT) images from 5166 patients were retrospectively reviewed. Correlations between RCMs and osteomeatal complex obstruction, accessory ostium presence, abnormalities of the middle turbinate, and nasal septal deviation were analyzed in the PNsCT images. The paranasal sinus anomalies on the side of the RCMs were compared to the contralateral side. Results: A total of 1880 RCMs were detected in 1429 (27.6%) of 5166 patients. At least one nasal-paranasal sinus anomaly was associated with 88.7% of the RCMs. In the descending order, accessory ostium presence, accessory ostium, middle turbinate anomalies, and nasal septal deviation are pathologies that accompany RCMs. When unilateral RCMs were compared with the normal side, significant correlations were observed between RCMs and osteomeatal complex obstruction, accessory ostium, and middle turbinate anomalies (p=0.001, p=0.016, and p=0.03, respectively). RCMs were commonly found on the same side as osteomeatal complex obstruction (p=0.001), middle turbinate anomalies (p=0.001), and accessory ostium (p=0.052). Conclusions: In this study, the coexistence of osteomeatal complex obstruction, accessory ostium, middle turbinate anomalies, and nasal septum deviation with RCMs was analyzed by investigating PNsCT findings in 5166 patients. The results show that RCMs are associated with pathologies that increase paranasal inflammation, such as osteomeatal complex obstruction, and are good markers for nasal-paranasal sinus anomalies. The presence of incidental RCMs should be a warning sign of nasal-paranasal sinus anomalies. Keywords: Paranasal sinuses, anomalies, nasal cavity, turbinates, computed tomography Öz Amaç: Maksiller sinüs retansiyon kistleri (MsRK) radyolojik incelemelerde sık karşılaşılan bulgular olmakla birlikte, MsRK'lerin gelişimi için risk faktörleri açık değildir. Bu çalışma MsRK'ler ile diğer nazal-paranazal sinüs anomalileri arasındaki korelasyonu değerlendirmek ve bu anomalilerin MsRK gelişimi için olası etkilerini ortaya koymak amacıyla yürütülmüştür. Yöntemler: Çalışmada, 5166 hastanın paranazal sinüs bilgisayarlı tomografi (PNsBT) görüntüleri geriye dönük olarak değerlendirildi. PNsBT görüntülerinde MsRK'ler ile osteomeatal kompleks obstrüksiyonu, aksesuar ostium varlığı, orta konka anomalileri, nazal septal deviasyon arasındaki korelasyonlar analiz edildi. MsRK olan taraftaki paranasal sinüs anomalileri, olmayan tarafla karşılaştırıldı. Bulgular: MsRK, 5166 hastanın 1429'unda (%27.6) toplamda 1880 olmak üzere saptandı. MsRK'lerin %88.7'sine en az bir nazal-paranazal sinus anomalisi eş-lik etti. Azalan sırada; osteomeatal komple...

I. Executive Summary Background The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS.
