RESUMEN
Rhinoplasty is the most common aesthetic surgery in Iran which is done more and more. In majority, lateral osteotomy is the integral part of rhinoplasty that has two major methods: external [perforating or non-continuous] and internal [endonasal or continuous]. It is the surgeon's choice according the experience and comfort. Edema and ecchymosis are major sequels of this operation. We compared these two techniques regarding ecchymosis and edema. It is done as a clinical prospective randomized trial on two 40- patient groups with informed consent. In one group, we did lateral external osteotomy and in another group, internal lateral osteotomy was done in the same condition. Data were gathered and recorded according visual scoring system which was done by two blinded examiners by comparing sample in data sheath with patient. We compared both sequels in second and seventh day. Edema was the same in both groups in second and seventh days. Ecchymosis was not significantly different in seventh day in both groups. But, ecchymosis was significantly less in internal group, comparing with External group in second days. External and internal osteotomy techniques were the same regarding edema but internal technique produced less ecchymosis in second postoperative day
