This study was conducted to investigate the vulnerability of the nasal bones following rhinoplasty. The incidence of nasal bone fracture in the general population was reviewed from the data available from the National Center for Health Statistics (NCHS). The NCHS report indicates an average of 51,200 nasal bone fractures each year for an average yearly population of 239,328,200 over a 5-year period for the United States, producing an average rate of 0.021 percent per year. The history of 1121 patients who had undergone routine rhinoplasty or septorhinoplasty on an elective basis was then investigated for possible fractures following rhinoplasty. Of this group, 24 patients (16 females and 8 males) sustained a total of 28 nasal bone fractures following rhinoplasty over a mean follow-up period of 4 years. This yields an actual or crude rate of 0.624 percent per year, as compared with the age-standardized rate of 0.485 percent, according to the indirect adjustment method. The time interval between the first nasal procedure and subsequent fracture varied greatly, spanning from 1 month to 6 years. The average time interval between the first nasal procedure and the subsequent fracture for 16 patients was less than 1 year. Over 70 percent of the patient population (n = 17) who sustained post-rhinoplasty fracture were under 30 years old at the time of the fracture. On the basis of the study, it was concluded that the incidence of nasal bone fracture following rhinoplasty (0.624 percent actual and 0.485 percent adjusted) is higher than that of fracture in the general population (0.021 percent) (p < 0.001).
本研究旨在调查隆鼻术后鼻骨的易损性。利用国家卫生统计中心（NCHS）提供的数据，回顾了普通人群中鼻骨骨折的发生率。NCHS报告显示，在美国5年期间，平均每年有51200例鼻骨骨折，年均人口为239328200人，年平均发生率为0.021%。随后，对1121例择期接受常规隆鼻术或鼻整形术的患者进行了调查，以了解隆鼻术后可能发生的骨折情况。在这组患者中，24例（16例女性和8例男性）在平均4年的随访期内隆鼻术后共发生28例鼻骨骨折。根据间接调整法，这得出的实际或粗略发生率为每年0.624%，而年龄标准化发生率为0.485%。首次鼻部手术与随后骨折之间的时间间隔差异很大，从1个月到6年不等。16例患者首次鼻部手术与随后骨折之间的平均时间间隔不到1年。隆鼻术后发生骨折的患者中，超过70%（n = 17）在骨折时年龄小于30岁。根据该研究得出结论，隆鼻术后鼻骨骨折的发生率（实际发生率为0.624%，调整后发生率为0.485%）高于普通人群骨折的发生率（0.021%）（p < 0.001）。
