In this study we aimed to compare external lateral osteotomy technique vs. internal one in the rhinoplasty. In this before-after clinical trial study 30 patients who were candidates for rhinoplasty involved. In each patient, external lateral osteotomy was performed on one side and internal lateral osteotomy was performed on the other side randomly. Information, including patients' age, sex, grade of edema and ecchymosis 1, 3, and 7 days after the surgery, and the type of lateral osteotomy, the amount of step deformity, the need for the specialist intervention, nasal bone mobility, and flail nasal bone was recorded and analyzed. The incidence of edema and ecchymosis on the first and the third day was statistically lower in the external method ( value < 0.001). Although the incidence of edema and ecchymosis on the seventh day was lower in the external method, it was not statistically significant ( value > 0.05). Forty seven percent of patients in the internal method and 36% of patients in the external method had step deformity ( value < 0.001). Fifty percent of patients in the internal method and 41% of patients in the external method needed the specialist intervention ( value > 0.05). Seventy four of patients in the internal method and 83% of patients in the external method had nasal bone mobility ( value > 0.05). Out of 30 patients, only one had flail nasal bone. Based on our findings, the external technique is suggested as a more effective and convenient method with less complications for inexperienced surgeons.
在本研究中，我们旨在比较鼻整形术中外侧截骨术的外部技术与内部技术。在这项前后对照的临床试验研究中，纳入了30名鼻整形术候选患者。对每位患者，随机在一侧进行外侧截骨术的外部技术，在另一侧进行外侧截骨术的内部技术。记录并分析相关信息，包括患者的年龄、性别、术后1天、3天和7天的水肿和瘀斑程度、外侧截骨术的类型、台阶畸形量、专科干预需求、鼻骨活动度以及连枷状鼻骨情况。外部技术组术后第一天和第三天水肿和瘀斑的发生率在统计学上较低（ 值<0.001）。虽然外部技术组术后第七天水肿和瘀斑的发生率较低，但差异无统计学意义（ 值>0.05）。内部技术组47%的患者和外部技术组36%的患者出现台阶畸形（ 值<0.001）。内部技术组50%的患者和外部技术组41%的患者需要专科干预（ 值>0.05）。内部技术组74%的患者和外部技术组83%的患者有鼻骨活动度（ 值>0.05）。30名患者中，只有1名出现连枷状鼻骨。根据我们的研究结果，对于经验不足的外科医生而言，外部技术被认为是一种更有效、更便捷且并发症更少的方法。
