“…3b). Goblet cells within the surface epithelium are less frequent in ACPs than in usual SNIPs, and surface squamous metaplasia is observed in ACPs but not as often in SNIPs [57,63]. The surface epithelium basement membrane is inconspicuous in most ACPs, whereas SNIPs, especially those associated with allergy, reveal a remarkably thickened basement membrane.…”

“…ACPs tend to develop in younger patients than classical SNIPs, affecting teenagers and young adults (mean 24-28 years) [55,60]. Symptoms are non-specific, most commonly including nasal obstruction and rhinorrhea [55,[60][61][62][63]. Patients tend to have a longer duration of symptoms with ACPs than with SNIPs [63].…”

“…Symptoms are non-specific, most commonly including nasal obstruction and rhinorrhea [55,[60][61][62][63]. Patients tend to have a longer duration of symptoms with ACPs than with SNIPs [63]. While the vast majority of ACPs are unilateral, synchronous bilateral involvement may be observed, along with bilateral maxillary sinusitis [61].…”

“…This results in partial degeneration and destruction of the endothelial cells. Cystic degeneration of the stroma is frequently observed, creating a loosely reticular pattern or ''pseudoangiomatous'' growth [63]. It is not uncommon to see partial to complete infarction, secondary fibrosis, minimal to extensive hemorrhage, and even organizing thrombus or papillary endothelial hyperplasia (Masson endothelial hyperplasia).…”

“…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).…”

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...

ObjectiveThis study aims to find the difference in clinical and immunopathological characteristics between children and adults with antrochoanal polyps (ACPs) in the Chinese population.MethodsThe clinical data of 69 patients diagnosed with ACPs were retrospectively analyzed. Cytokine levels in 16 controls and 40 ACPs tissues were determined by quantitative real‐time polymerase chain reaction (qPCR). The expression of matrix metalloproteinase (MMP)‐9 was measured using qPCR, immunofluorescent staining, and western blot.ResultsThere were 51 (73.9%) children (<18 years old) and 18 (26.1%) adults (≥18 years old). The sex ratio differed significantly between the two groups (p = 0.0032). There were no significant differences in the nasal side of ACPs and approaches to surgery between the two groups. In both groups, the most common symptom was nasal obstruction, followed by nasal discharge. As for associated nasal diseases, there was a significant difference between the two groups in septal deviation (p = 0.0223). Adult patients showed significantly higher expression of IL‐8 mRNA than children (p = 0.0424). The mRNA and protein levels of MMP‐9 were also significantly higher in adult patients than in children (p = 0.0498 and 0.0009, respectively).ConclusionIn the Chinese population, the comorbidities and immunopathological characteristics of adult ACP patients are different from those of children. The level of IL‐8 and MMP‐9 was significantly higher in ACPs of adults than in children, which may contribute to the more severe tissue remolding in adult ACP patients.Level of Evidence3 Laryngoscope, 2023
