To the plastic surgeon, the nose is one of the most interesting and challenging facial structures and its anatomy is well defined. From the point of view of aesthetic surgery, the nasal tip area is an especially important structural unit, and the most difficult to address in rhinoplasty. The objective of this study was to demonstrate the existence of the nasal interdomal fat pad as a distinct anatomical structure that occupies the interdomal space and is apart from subcutaneous fat. In our study we proved the existence of the interdomal fat pad by histochemical studies and anatomical observations in 88 patients who underwent primary external rhinoplasty and three fresh cadavers. All specimens were examined by hemotoxylen-eosin, Sudan black, and oil red staining, as well as S100 protein immunoreactivity staining. The mass of the interdomal fat pad was greater in patients with bulbous noses and/or divergent alar cartilage than in patients with thin skin. We speculated that the interdomal fat pad may be the major anatomic structure contributing to unexpected results in difficult cases, such as those involving bulbous noses. According to our study, the existence of the interdomal fat pad should be kept in mind during the preoperative planning of rhinoplasty.
对于整形外科医生而言，鼻子是面部最有趣且具挑战性的结构之一，其解剖结构明确。从美容外科的角度来看，鼻尖区域是一个特别重要的结构单元，也是鼻整形术中最难处理的部位。本研究的目的是证明鼻间脂肪垫作为一种独特的解剖结构的存在，它占据鼻间间隙且与皮下脂肪不同。在我们的研究中，我们通过对88例行初次鼻外整形术的患者及3具新鲜尸体进行组织化学研究和解剖观察，证实了鼻间脂肪垫的存在。所有标本均进行苏木精 - 伊红染色、苏丹黑染色、油红染色以及S100蛋白免疫反应染色检查。球鼻和/或鼻翼软骨分离的患者鼻间脂肪垫的量比皮肤薄的患者更多。我们推测鼻间脂肪垫可能是导致复杂病例（如球鼻病例）出现意外结果的主要解剖结构。根据我们的研究，在鼻整形术的术前规划中应考虑到鼻间脂肪垫的存在。
