【摘要】：[目的] 1通過耳廓軟骨的解剖學(xué)研究,指導(dǎo)臨床手術(shù)中在保持耳廓形態(tài)不受影響的前提下最大量采取耳廓軟骨。2分析中國人鼻尖形態(tài)學(xué)特點,應(yīng)用耳廓軟骨移植行鼻尖成形術(shù),并觀察及評價臨床療效。 [方法] 1通過尸體耳廓軟骨的解剖,了解耳廓軟骨支架的支撐體系特點,通過對耳廓軟骨的解剖學(xué)和力學(xué)分析,找出維持耳廓形態(tài)的關(guān)鍵解剖部位,以及非維持形態(tài)的軟骨部位,明確可采取軟骨的解剖位置和范圍,選擇最佳手術(shù)切口位置,指導(dǎo)臨床采取耳廓軟骨時避免損傷耳部輪廓及支撐結(jié)構(gòu)。 2臨床觀察并分析中國人鼻尖的形態(tài)特點,應(yīng)用耳廓軟骨移植鼻尖成形術(shù),評價其療效。 [結(jié)果] 1維持耳廓形態(tài)的結(jié)構(gòu)包括耳輪、耳輪腳、對耳輪、對耳輪上腳及下角、耳屏、對耳屏,對耳輪下腳、耳輪腳、耳屏間切跡下方耳甲與外耳道后壁移行區(qū)及耳甲腔內(nèi)側(cè)緣與顱骨接觸緊密,維持耳廓的輪廓和耳顱角的形成�？刹扇≤浌俏恢冒ǘ淄�、耳甲腔及耳甲隆起的外側(cè)部。2手術(shù)最佳切口選在耳廓后方耳顱溝內(nèi)。3根據(jù)臨床患者鼻尖缺陷的特點,將鼻尖形態(tài)分成兩類：(1)鼻尖突出度不足,鼻尖旋轉(zhuǎn)角基本正常；(2)鼻尖突出度不足,鼻尖旋轉(zhuǎn)角過大。臨床應(yīng)用耳廓軟骨移植鼻尖成形術(shù),術(shù)后效果良好,鼻尖外形明顯改善。 [結(jié)論] 耳廓軟骨能夠夠提供足夠量的移植物行鼻尖成形術(shù)。中國人普遍存在的鼻尖部缺陷為鼻小柱短,鼻尖突出度不足,旋轉(zhuǎn)度過大。通過耳廓軟骨移植,增加鼻小柱支撐力,提高鼻尖突出度、豐滿鼻尖下小葉以及減小鼻尖旋轉(zhuǎn)角,充分改善鼻尖形態(tài),是一種療效肯定、結(jié)果滿意的手術(shù)方式。
[Abstract]:[Objective]
1, through the anatomical study of auricular cartilage and guiding the clinical operation, we should take the most ear cartilage.2 to analyze the morphological characteristics of the nasal tip of the Chinese people, and apply auricular cartilage transplantation to do the nasal tip plasty, and observe and evaluate the clinical efficacy.
[method]
1 by the autopsy of auricular cartilage, understand the characteristics of auricle cartilage scaffold support system, through the analysis of auricular cartilage anatomy and mechanics, find out the key to maintaining the pinna morphology anatomy and maintain cartilage part of the form, can be taken to clear anatomical position and range of cartilage, choose the best surgical incision position, avoid injury and contour support structure for guiding clinical ear auricle cartilage.
2 the morphological characteristics of the Chinese nasal tip were observed and analyzed, and the auricular cartilage was used to transplant the tip of the nose to evaluate the curative effect.
[results]
1 maintain the ear form structure includes the helix, antihelix crus of helix, antihelix, foot and corner, tragus, antitragus, antihelix crus, foot, intertragic notch below the ear canal wall and transitional zone and concha margin of the skull close contact, maintain the shape of the ear the profile contour and the cranioauricular angle. Can take the position including the concha cartilage, best incision lateral.2 surgery and auricular concha swelling in auricle rear cranioauricular ditch.3 according to the characteristics of defects of nasal tip patients, the nose shape is divided into two categories: (1) the outstanding problems, the tip of the nose the rotation angle is normal; (2) the tip protrusion, tip rotation. Clinical application of auricular cartilage graft in nasal tip plasty, postoperative effect is good, the appearance of the nasal tip was significantly improved.
[Conclusion]
Can provide the plant for auricular cartilage nasal tip plasty shift a sufficient amount of defects of nasal tip. Chinese for nasal columella short nose, prominent problems, rotating through the large. Through auricular cartilage transplantation, increase the columella support force, improve the nasal tip protrusion, plump nose lobule and decreasing tip rotation angle, fully improve the nose shape, is an effective surgical method, with satisfactory results.
