毛囊单位移植过程和存在的问题 总被引:1,自引:1,他引:0
1994年,BL Limmer首次提出"毛囊单位移植(follicular unit transplantation, FUT)"的概念,此概念的提出标志着自体毛发移植技术FUT时代的到来.目前,经过多年的探索和改进,FUT技术已日臻完善,并在临床中得到广泛应用[1-2];尤其在发际线、胡须、阴毛、眉毛和睫毛等缺失的治疗方面取得了较好的效果[3-6].但供区不足、手术效率低是FUT技术存在的两大问题. 相似文献

目的探索毛发移植技术修复发际线轮廓缺陷的应用效果。方法术前仔细设计发际线和计算所需移植毛发的数量。切取枕后带发皮片,在4~5倍放大镜下精细分割,制备成不同粗细的单株毛囊和单位毛囊。根据受区毛发的走行及自然生长方向,用1.5mm蓝宝石裂隙刀制备微小裂隙,将制备好的单株毛囊和单位毛囊间隔插入裂隙。结果临床随访6个月显示,发际处移植毛发生长良好,与原有毛发融为一体,成活率达到95%。403名发际缺陷患者中有361例对美容效果表示满意,但是仍有部分颞额角脱发明显和瘢痕严重的患者需要二期加密手术。结论用单株毛囊和单位毛囊移植技术改善发际线缺陷,对毛囊分离技术的要求较高,手术设计合理,术后恢复迅速,外观自然、逼真,是较理想的治疗手段。 相似文献

Follicular unit extraction (FUE), now named as follicular unit excision, is one of the methods of harvesting hair follicles from the donor area for implanting in the recipient area. The occipital scalp area is the most common donor area, but nonscalp donor areas like beard, chest, and other hairy body parts can be used as donor hair follicle area. The extraction of the hair follicle leaves a tiny circular scar over the donor area. Over the past 20 years, various devices for FUE have been developed, starting from manual, simple motorized to highly advanced motors with rotation, oscillation, and vibration. Similarly, different types of punch are used: dull, sharp, ultrasharp, serrated, hybrid and specially designed punch blade for long hair follicles harvesting in various diameters from 0.7 mm to 1.1 mm. The follicles can be harvested either by manual method or by motorized method. 相似文献

Harvesting of beard and body hair follicles for transplantation can be an effective form of treatment for appropriate patients. These patients may have had prior scalp transplantation and require repair but do not have sufficient scalp donor follicles remaining. Other patients will have these hairs mixed with scalp hairs to produce a greater density of hair on the bald scalp. Follicular unit excision (FUE) is preferred for body and beard follicle harvesting. Not all body hair is suitable for transplantation. Only hairs that are similar in appearance and behavior to scalp hair are suitable for transplantation to the scalp. The best nonscalp sources are the beard and anterior torso. Hairs from other body sites may be used for transplantation to the eyebrows. The standard techniques of FUE harvesting and anesthesia must be modified from those used in scalp harvesting to be safe and effective. With proper patient selection and technique, a significant cosmetic benefit can be achieved from these procedures. 相似文献

The evolutionary process of modern hair transplantation began with the plug era and, transitioning through a period of minigrafting and micrografting, finally led to follicular unit transplantation (FUT). Apart from the expansion of donor:recipient ratio, this technique produces an excellent esthetic result, indistinguishable from the natural hair. The merit of strip harvest lies in the maximum amount of follicular unit harvest, minimizing the amount of hair follicle transection, and producing a single scar, irrespective of number of sessions. This article summarizes the prerequisites, indications, contraindications, and technique of strip harvest. 相似文献

The main aim in surgical hair restoration is to restore hair, making the scalp look natural. Interviews with earlier patients who received hair transplants revealed that their complaints were - a straight anterior hairline that looked unnatural, and hair that looked like 'sprouted grass'. The use of follicular unit transplantation (FUT) technique, where hair roots are harvested under magnification, is becoming widespread. In this technique, hair roots are harvested into natural follicular units that contain 1-4 hair roots. In this article, we present our results related to hair transplantation by FUT technique, performed on 120 patients between the ages of 21 and 75 years with male-pattern hair loss. We made simple yet useful interventions to avoid the occurrence of the above-mentioned problems. Initially, drawings based on the middle line and the two temporal regression points were made for a natural-looking anterior hairline. Following this, irregular seeding was done instead of seeding in rows, to obtain a natural hairline. To avoid the 'sprouted grass' look, single hair roots were placed on the anterior hairline taking into consideration the direction of hair growth. However, the FUT technique is not adequate on its own for natural-looking hair restoration. Good planning and creation of an anterior hairline suited to the individual's forehead structure is fundamental for successful results. In addition, we believe that hair texture is very important in hair transplantation and additional care should be given particularly to patients with dark-coloured and hard hair. 相似文献
