超声在鼻尖穹窿部脂肪垫探查中的应用价值

Application of Ultrasonography in the Detection of Nasal Interdomal Fat Pad

目的评估超声在鼻尖穹窿部脂肪垫(IFP)探查中的应用价值。方法以在北京协和医院行鼻部或其他手术的38例患者为研究对象,采用超声技术探查鼻尖IFP的形态、结构、层次、位置和大小,并与术中所见进行对比。结果超声图像显示,32例(84.2%)IFP与皮下脂肪有较明显的分界;6例(15.8%)边界显示欠清晰,其中2例为注射隆鼻术后,4例为假体隆鼻术后。超声测量结果显示,所有患者IFP的平均长、宽、高分别为(11.81±1.28)、(2.49±0.57)、(1.90±0.61)mm;男女两性IFP的平均长、宽、高间差异无统计学意义(P均>0.05);鼻尖肥大组患者IFP的长、宽、高明显大于正常组患者(P均<0.05),唇裂继发鼻畸形组与正常组相比差异无统计学意义(P均>0.05)。结论超声在术前可准确评估IFP的大小和形态,有助于鼻整形手术的成功。

Objective To evaluate the application of ultrasonography in the detection of nasal interdomal fat pad（IFP）.Methods Thirty-eight patients who underwent open rhinoplasty and other surgeries in our hospital were enrolled in this study.All patients were studied by ultrasonography to evaluate the shape,structure,size,and location of IFP.The results of ultrasonography were compared with intraoperative findings.Results The boundaries between IFP and the subcutaneous fat were clear under ultrasonography in 32 patients（84.2%）,but were not clear in 6 patients（15.8%）who had undergone injection rhinoplasty（n=2）or augmentation rhinoplasty（n=4）.As shown by ultrasonography,the average length,width,and height of IFP were（11.81±1.28）mm,（2.49±0.57）mm,and（1.90±0.61）mm,respectively,which were not significantly different between male and female patients（P〉0.05）.In addition,the length,width,and height of IFP were significantly larger in nasorostral hypertrophy group than in normal group（P〈0.05）,but showed no significant difference between the nasal deformity secondary to cleft lip group and normal group（P〉0.05）.Conclusion Ultrasonography can accurately evaluate the size and morphology of IFP pre-operatively,and therefore is helpful to ensure the success of rhinoplasty.
