“…11 With the development of endoscopic sinus surgery (ESS), CT, and MRI, it is now possible to trace the original site of the tumor, regardless of the tumor size. 11 Although Chawla et al 12 have demonstrated that the osteitis sign and neoosteogenesis on the CT scans could be used to identify the site of attachment of the SNIP, Fang et al 10 have indicated that preoperative MRI may provide a better option to accurately predict the original site of the SNIP than CT, and thus may facilitate accurate and complete removal of the SNIP. 10 Staging is important in prognosis of the disease 9 and in achieving a satisfactory surgical outcome.…”

Background We aimed to assess the recurrence risk of sinonasal inverted papillomas (SNIPs), based on a staging system developed according to the originating site of SNIP. Methods A total of 200 patients with SNIP were enrolled, and a staging system was developed based on the originating sites and corresponding recurrence rates of tumor in the patients. In the verification phase, 675 patients with SNIPs were enrolled as above, and the originating sites of the SNIPs were confirmed by an endoscopic sinus surgery. Cluster analysis was performed to determine the stage for each SNIP. Results Overall, 608 patients completed the study. SNIP recurrence rates for stages 1‐4 were 0 (n = 43), 4.0% (n = 420), 13.4% (n = 134), 36.4% (n = 11), respectively (total = 6.4%). Conclusions The origin site‐based classification of SNIP may aid surgeons in selecting appropriate endoscopic surgical approaches to minimize the risk of recurrence.

“…Özellikle levha şeklindeki hiperosteozisin tümörün kaynaklandığı yeri gösterdiği savunulmaktadır. [16] Bu spesifik görüntünün tespit edilmesinin cerrahi yönteme karar vermede oldukça faydalı olacağı kanaatindeyiz. İnflamatuvar sinonazal hastalık-larda sklerozisin diffüz, İP'lerde ise sadece tümörün kaynaklandığı alanda fokal olarak görülmesi tomografinin ayırıcı tanıda dahi faydalı olduğunu göstermektedir.…”

ÖZAmaç: Bu çalışmada inverted papillomlu hastalarda endonazal endoskopik ve kombine yaklaşımın sonuçları araştırıldı. Hastalar ve Yöntemler:Ocak 2010 -Aralık 2015 tarihleri arasında sinonazal bölgede inverted papillom tanısı konulan ve endonazal endoskopik yaklaşımla tedavi edilen 24 hastanın (21 erkek, 3 kadın; ort. yaş 57.9±1.2 yıl; dağılım 42-69 yıl) dosyası retrospektif olarak incelendi. Hastaların demografik verileri, hastaneye başvuru yakınmaları, uygulanan tedavi ve tedavi sonrası takipleri ve son durumları hakkındaki bilgiler elde edildi. Hastaların ameliyat öncesi tümör yerleşim yeri ve tümörün komşu yapılarla olan ilişkisini ortaya koymak için aksiyal ve koronal planlarda çekilmiş olan bilgisayarlı tomografi kesitleri incelendi. Bulgular:Hastalığın erkeklerde görülme oranı kadınlardan yedi kat daha fazla idi. Hastaların en sık şikayeti burun tıkanıklığı (%100) idi. Kitle 14 hastada sağ, 10 hastada sol tarafta yerleşimli idi. İki taraflı kitle ile karşılaşılmadı. Tümör en sık orta meatustaki yapılardan kaynaklanmakta idi. Hastaların tamamına endonazal endoskopik cerrahi yapıldı ve ortalama 23.5±3.1 aylık takiplerinde hiçbir hastada nüks tespit edilmedi.Sonuç: Son zamanlarda görüntüleme sistemlerinin, endonazal cerrahide kullanılan enstrümanların gelişmesi seçilmiş inverted papillom hastalarında endonazal endoskopik cerrahiyi etkili ve güvenilir bir tedavi seçeneği haline getirmiştir.Anahtar sözcükler: Endonazal endoskopik cerrahi; epidermoid karsinom; inverted papillom. ABSTR ACTObjectives: This study aims to investigate the results of endonasal endoscopic and combined approach in patients with inverted papilloma. Patients and Methods:We retrospectively analyzed the records of 24 patients (21 males, 3 females; mean age 57.9±1.2 years; range 42 to 69 years) who were diagnosed with inverted papilloma in the sinonasal region and treated with endonasal endoscopic approach between January 2010 and December 2015. The demographic data of the patients, their visiting complaints, the treatment applied, their follow-up after the treatment and the information about their final status were obtained. Computed tomography scans performed in axial and coronal planes were examined to reveal preoperative tumor localization of the patients and its relationship with neighboring structures. Results:The incidence among males was seven times higher than females. The most common complaint of the patients was nasal obstruction (100%). The mass was located on the right side in 14 patients and on the left in 10 patients. No bilateral masses were observed. Tumors were mostly originated from structures in the middle meatus. Endonasal endoscopic surgery was performed to all patients, and no recurrence was detected during a mean follow-up period of 23.5±3.1 months. Conclusion:Recent developments in imaging systems and instruments used in endonasal surgery make endonasal endoscopic surgery an effective and safe treatment option in selected patients with inverted papilloma.
