“…An accessory ostium can lead to chronic mucosal inflammation of the paranasal sinuses due to circulation between the natural and accessory ostium (19,20). It has also been suggested that antrochoanal polyps (ACPs) could arise from an antral cyst (21). In one study, 70%-100% of ACPs protruded from an accessory ostium (22).…”

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...

“…Clinical presentation, endoscopic examination or biopsy are unreliable in making that distinction. 6 Both types of choanal polyp have an equal sex distribution. 7 Both antrochoanal and sphenochoanal polyps most commonly present with unilateral nasal blockage, as in all our cases.…”

“…Both types of polyps are indistinguishable histologically making it impossible to differentiate the two on that basis. 6 The best way to distinguish an antrochoanal polyp from a sphenochoanal polyp is with the use of computed tomography or magnetic resonance imaging of the paranasal sinuses. 8 Etiology of this choanal polyps still remains uncertain, earlier attempts to link it with IgE mediated allergic disorders does not hold true.…”

<p class="abstract">Choanal polyp arising from the sphenoid sinus and presenting at the choana are rare. These are known as sphenochoanal polyp. We present a case of sphenochoanal polyp and its clinical features and surgical management is discussed. Our aim in this case was to properly delineate the origin of the polyp and differentiate it from other lesions such as the antrochoanal polyp and meningocele, followed by meticulous endoscopic excision of the polyp. Radiological investigations include a CT scan paranasal sinuses or a MRI diagnostic nasal endoscopy will confirm the diagnosis. Once the diagnosis is made surgical removal must be done<span lang="EN-IN">.</span></p>

“…It is suggested that choanal polyps develop from a precursor intramural cyst in the antrum or sphenoid sinus [3]. Benign intramural cysts, found in 4 % of the normal asymptomatic population, have the potential to gradually enlarge through the ostium, and develop into a choanal polyp.…”
