This research was conducted regarding to the prevalence of rhinoplasty surgery , the importance of the residual scar analyze including columellar scar after surgery, different results caused by the effect of incision type in this surgery and lack of enough data and experimental report on it. Materials and Methods: The research was conducted by COHORST STUDY plan. 120patients with indications of open rhinoplasty was selected by sampling method and located in three groups with three incision types including V, Invert V and Step incision. The surgery was done in same condition from surgical aspect and followed for 6 months. The analyze of columellar scar was investigated in three indexes of scar outbreak, notching and depression or bump in three groups by K2 test and satisfaction level of the patients was measured with VAS criteria, and was analyzed with MANN-U-WHITNEY test. Results: The research was conducted on 120 samples including V type of incision with 74 samples, Invert V with 33 samples and STEP incision with 13 samples. Scar formation in 25/7 %, 27/2 % and 23/8 % respectively was found (p<0.8) and notching and depression or bump outbreak was the same in three groups (p<0.9). The satisfaction in 3 groups was as follow 7.8 1±.7, 7.7 ±3.2, 7.6±1.8 ( p<0.8). Conclusion: It seems all three incision types lead to the same result in open rhinoplasty. Key words: Columellar scar, incision type, open rhinoplasty, patient satisfaction. https://jcr.tums.ac.ir/index.php/jcr/article/view/86 https://jcr.tums.ac.ir/index.php/jcr/article/download/86/127
