目的:通过比较三种不同全耳再造手术方式术后支架外露的发生情况,为耳再造手术方式的选择提供依据。方法:对369例全耳再造术分别采用耳后乳突区皮肤扩张后肋软骨支架耳再造(软骨组)、颞浅筋膜瓣翻转Medpor材料耳再造(Medpor组)及颞浅筋膜瓣翻转肋软骨耳轮联合Medpor耳基耳再造手术(复合组),比较不同全耳再造术后支架外露的发生率、发生部位、出现时间及与患者年龄、手术时期等方面的差异。结果:软骨组、Medpor组及复合组支架外露发生率分别为7.1%、12.9%及6.7%,三者比较差异无统计学意义(P>0.05)。三组中,耳轮外上缘均为外露比例最高部位,出现时间均多在术后3月内发生。软骨组支架外露发生率在18岁以上者最高,Medpor组支架外露发生率则在18岁以上者最低(P<0.05)。近5年来手术者支架外露比例较前5年降低。结论:不论选择何种手术方式,均不能完全杜绝支架外露的发生,采用何种方法要依患者的情况及术者对手术方式的掌握情况来综合考虑。但对于6~12岁少儿,采用肋软骨法再造为宜;而对于大于18岁的成人,则采用Medpor法再造为宜。  相似文献

When an auricular defect is caused by high‐energy trauma that causes damage to the surrounding tissues, the patient may be not a candidate for reconstruction with local flaps and free tissue transfer may be necessary. Here we present a case of total auricular reconstruction in a 27 year‐old man who had total loss of the left ear and traumatized temporal skin and fascia. A radial forearm flap prelaminated by a porous polyethylene implant was employed. A “printed” ear made of silicone, based on the patient's CT ‐ scan of the contralateral ear, was used for intraoperative molding of the future reconstruction. Prolonged prelamination time and surgical delay (three months) were performed to reduce edema, distortion and loss of definition of the framework after revascularization. After subsequent integration and neovascularization of the added tissue, the prelaminated flap was transferred. Flap reinnervation was also performed by direct coaption of the great auricular nerve to the lateral antebrachial cutaneous nerve. The flap fully survived and there were no complications in the early postoperative period. Between 3 and 6 months, the patient returned to normal ranges in terms of warmth and cold, and recovered the discriminative facial sensibility. After one year the auricular reconstruction was intact and satisfactory aesthetic results were achieved. This method may offer a satisfactory solution for a difficult problem and may be considered for acquired total ear defects.  相似文献

The Medpor implant is another choice for a new auricular framework besides autogenous costal cartilage. However, its relatively frequent exposure and less-matching skin coverage discourage surgeons from using it. In this article, we present a new two-flap method, a combination of the temporoparietal fascial flap and the expanded skin flap, for wrapping the Medpor implant in microtia reconstruction. A staged surgical procedure was performed, including soft tissue expansion in the mastoid region, soft tissue expander removal, expanded skin flap and temporoparietal fascial flap formation, Medpor framework implantation, and the combined two-flap envelopment. Conventional lobule transposition and tragus reconstruction were accomplished for selected patients. In this study, a total of 22 microtias were reconstructed consecutively using this method. Eighteen patients were followed since the first surgery. The postoperative follow-up time ranged from 3 to 12 months. The draped soft tissue covering was thin enough to show the reconstructed ear with excellent, subtle contour when edema gradually vanished 3-6 months postoperatively. The new ear had a stable shape, and its skin color and texture matched the normal surrounding skin very well. No exposure or extrusion of the framework was observed in the series. The Medpor implant enveloped by both a temporoparietal fascial flap and an expanded cutaneous flap appears to be a promising alternative for the auricular framework in microtia reconstruction. Because of the wrapping tissues, auricular construction using a Medpor implant can be a safe, steady, and easily acceptable choice for both microtia patients and their physicians.  相似文献

A sufficient skin envelope of good quality as well as definite auricular framework is a prerequisite for a successful auricular reconstruction. Various surgical techniques, such as recruitment of mastoid skin, skin graft, tissue expansion, and so on, have been used to get the necessary skin for covering of the auricular framework. However, debates about the drawbacks of these techniques have continued. In this article, I report on a new skin flap method for total auricular reconstruction, which is an extended scalp skin flap in continuity with postauricular skin flap and isolated conchal flap. Between January 2009 and March 2010, a total of 20 patients underwent an auricular reconstruction using a Medpor framework (Porex Surgical, Inc, Newnan, GA) and the new skin flap method. Follow-up time range was 4 to 17 months. The reconstructed ear showed no definite true hair growth except for some fine hair, which can be ignored. More favorable results such as a good color matched skin, well-formed ear convolution, no other donor site scars can now be achieved using this new method.  相似文献

Auricular reconstruction is a unique area of facial plastic surgery where a wide array of reconstructive options often must be considered. The external ear is unique in its aesthetic role where the normal auricle often goes unnoticed; yet even a small irregularity can stand out and become conspicuous. The reconstruction of large or total auricular defects is a combination of science and art. Two forms of auricular reconstruction are discussed: (1) those for a congenitally abnormal shape but no acquired tissue deficiency, that is, otoplasty, and (2) repairs requiring a reconstruction of discrete loss of tissue. A general algorithm is presented that can assist with flap selection and covers the techniques for grafts, framework repair, local and pedicled flaps, temporoparietal facial flaps, and auricular prostheses.  相似文献

In the case of traumatic defects or congenital malformations, ear reconstruction using a porous polyethylene framework covered by a temporal parietal fascia flap (TPFF) is one of the best known procedures. Due to the material’s porosity, blood vessel and tissue ingrowth into the grafts is possible. The complex form of the ear to be reconstructed is achieved within a relatively short time and with tolerable discomfort for the patient; this can even be achieved in one surgical session if tragus reconstruction is successful in the first session. During surgery, particular attention should be paid to preserving the course of the superficial temporal artery and veins, as well as their integration into the TPFF. The ear framework is tailored individually using the implant components“ear base” and“helical rim”, while the contralateral ear is used as the template for the ear to be reconstructed. The framework is covered by the TPFF, which is elevated by a combination of mastoid skin incision and endoscopy from the cranial end of the fascia flap. The TPFF is laid loosely, without any tension, over the entire framework and then covered with the available local skin, retroauricular full-thickness skin from the healthy side and groin skin. Skin quality should be taken into consideration in advance with regard to the expected outcome.  相似文献

To reconstruct a major middle third auricular defect, a two-stage operation is usual, using a skin flap with cartilage support. In this paper, a one-stage operation for an acquired ear defect using an auricular cartilage sling and temporal fascial flap with skin grafting is reported. The auricular cartilage graft was harvested along the antihelix and used for the reconstruction of the helical rim. This is a simple, easy, and safe method of one-stage reconstruction for an acquired ear defect in properly selected patients.  相似文献
