We think that caution should be exercised when using these new hematological parameters which can be affected by many factors for the presence, severity and recurrence risk of nasal polyposis, and literature data should be proven by conducting different and objective studies on this subject.

β-hydroxy fatty acids are a major component of lipid A moiety of lipopolysaccaride. We aimed to investigate the role of free β-hydroxy fatty acids on inflammation, as well as to evaluate their effects on cytokine release from human blood cells, and whether they exist in plasma of patients with chronic inflammatory diseases with/without insulin resistance. Peripheral venous blood was incubated with β-hydroxy lauric and β-hydroxy myristic acids (each 100 ng, 1 μg, 10 μg/mL) up to 24 hours. Cytokines were measured from culture media and plasma. Free fatty acids and biochemical parameters were also measured from patients' plasma. Only β-hydroxy lauric acid significantly stimulated interleukin-6 production at 10 μg/mL compared to control (533.9 ± 218.1 versus 438.3 ± 219.6 pg/mL, P < .05). However, free β-hydroxy lauric and myristic acids were not found in patients' plasma. Therefore, free β-hydroxy lauric and myristic acids do not seem to have a role on sterile inflammation in chronic inflammatory diseases associated with insulin resistance.

The aim of this prospective study was to evaluate the effect of modified extracorporeal endonasal septoplasty on nasal tip shape and function in patients with severe caudal septal deviation. Methods: The study population comprised of 55 patients undergoing modified extracorporeal endonasal septoplasty, which called marionette septoplasty. To analyse the aesthetic objective outcomes, postoperative photographs were measured for projection index (PI), tip projection (TP), nasolabial angle (NLA), tip deviation angle (TDA), nasofrontal angle (NFA), supratip height (STH), columellar height (CH), at three times (2 weeks, 3, and 6 months after surgery) and were compared with preoperative photographs. Functional and aesthetic outcomes were also evaluated using nasal obstruction symptom evaluation (NOSE) scale and standardized cosmesis and health nasal outcomes survey (SCHNOS). Results: Between the pre-and post-operative 6th-month examinations, a significant increase in PI and TP were 7%, and 5% respectively. There was a significant alteration in the NLA and TDA values following the last examination (mean difference ± standard error of mean 9.68 ± 0.9 °and 1.5 ± 0.8 °, respectively). Moreover, the technique did not make a significant change in the final NFA, STH, and CH, measurements. Following surgery, the NOSE and SCHNOS scores were decreased significantly and the improvement continued over time until the last examination. Conclusion: The present study findings suggest that the marionette septoplasty technique is an effective to correct and stabilize severe caudal septal deviations. This technique also can provide tip support and protection with a low incidence of dorsal irregularity.

Amaç Bu radyo-anatomik çalışma ile bölgemizdeki 18 yaş altı ve üstü populasyonun anterior kafa tabanı anatomisi ile ilgili veri elde etmek ve normatif verilerin elde edilmesi ile komplikasyon oranlarının azaltılması amaçlanmıştır.
