The mean platelet volume and neutrophil-to-lymphocyte ratio values made us think that these parameters were quick, inexpensive and reliable inflammatory follow-up parameters and could be easily integrated into daily practice for peritonsillar abscess treatment except platelet count.

Background: Sphenoethmoid cells may be above the sphenoid sinus with/ or without con-tact to optical nerve. Although sphenoethmoid cells are theoretically considered to possibly influence the sphenoid sinus volume, we could not find any study in the literature on this issue.Aims: The aim of our study was to detect sphenoethmoid cells and measure the sphenoid sinus vol-ume using multiplanar computerized tomography and also investigate the correlation between the presence of sphenoethmoid cells and the sphenoid sinus volume.Methods: Retrospectively 141 patients who had available paranasal computerized tomography images were included in this study. The sphenoid sinus volumes of each patient were calculated individually for each side, and the relationship between the presence of sphenoethmoid cell and sphenoid sinus volume was investigated.Results: Sphenoethmoid cells were detected at 106 (37.5%) of the total 282 sides in 141 patients. No gender difference was observed. The total sphenoid sinus volume was significantly lower in the group of patients who had bilateral sphenoethmoid cells than in the sphenoethmoid cell negative group. In patients with a unilateral sphenoethmoid cell, a significant decrease in the sphenoid sinus volume was observed only for the side where the sphenoethmoid cell was located.Conclusion: It was observed that the sphenoethmoid cells caused a significant reduction in the sphe-noid sinus volume on the side where they were located. In the case of low sphenoid sinus aeration, the sphenoethmoid cell should be kept in mind. Further studies with an extended patient series are required to explore this issue.

The prevalence of sphenoiditis appears to be higher in patients with Onodi cells. However, it is not possible to state that Onodi cells are the single factor that causes this disease. Further studies are needed to investigate contributing factors related to sphenoiditis.

Özet: Nazal septum deviasyonu olan pediatrik hastalarda maksiller sinüsün volümetrik analizi Amaç: Nazal hava ak›m›n› azaltan ve oksijenasyonu bozan septal deviasyon gibi sebepler, maksiller sinüs hacmini etkileyebilir. Çal›flma-m›zda, retrospektif olarak nazal septal deviasyonlar›n maksiller sinüs hacmini nas›l etkiledi¤ini araflt›rmay› amaçlad›k. Yöntem: Kulak burun bo¤az poliklini¤inde kronik bafla¤r›s› etiyolojisini ayd›nlatmak üzere paranazal sinüs bilgisayarl› tomografisi çekilen ve intrakraniyal bir sebep bulunamayan 103'ü erkek ve 124'ü k›z olmak üzere toplam 227 olgu, nazal septal deviasyonu olup ilave sinonazal bulgusu olmayanlar ile nazal septal deviasyonu ve ilave sinonazal bulgular›ndan hiçbiri olmayanlar olarak iki gruba ayr›ld›. Maksiller sinüs hacmi gruplarda her olgu için hesapland›. Nazal septum deviasyonu ile maksiller sinüs hacmi aras›ndaki iliflki araflt›r›ld›. Bulgular: Çal›flmam›zda nazal septum deviasyonu olan grubun maksiller sinüs hacimleri ile (29.34±7.46 cm 3) ve nazal septum deviasyonu olmayan grubun maksiller hacimleri (27.89±8.51 cm 3) aras›nda istatistiksel fark olmad›¤› tespit edildi (p>0.05). Nazal septal deviasyon aç›-s› ne olursa olsun sa¤, sol ve toplam maksiller sinüs hacimlerinin etki-lenmedi¤i gözlendi. Hem sol hem de sa¤ tarafl› nazal septum deviasyonunun sa¤, sol ve toplam maksiller sinüs hacimlerine herhangi bir etkisi yoktu. Sonuç: Nazal septum deviasyonu olan ve olmayan pediatrik yafl grubundaki çocuklar›n maksiller sinüs hacimleri aras›nda herhangi bir fark gözlenmemifltir. Nazal septum deviasyonu varl›¤› veya fliddetinin de maksiller sinüs hacminin üzerinde herhangi bir etkisi olmad›¤› sonucuna var›lm›flt›r.
