Acne surgery is the use of various surgical procedures for the treatment of postacne scarring and also, as adjuvant treatment for active acne. Surgery is indicated both in active acne and post-acne scars. PHYSICIANS' QUALIFICATIONS: Any Dermatologist can perform most acne surgery techniques as these are usually taught during postgraduation. However, certain techniques such as dermabrasion, laser resurfacing, scar revisions need specific "hands-on" training in appropriate training centers.
Most acne surgery procedures can be performed in a physician's minor procedure room. However, full-face dermabrasion and laser resurfacing need an operation theatre in a hospital setting. ACTIVE ACNE: Surgical treatment is only an adjunct to medical therapy, which remains the mainstay of treatment. Comedone extraction is a process of applying simple mechanical pressure with a comedone extractor, to extract the contents of the blocked pilosebaceous follicle. Superficial chemical peel is a process of applying a chemical agent to the skin, so as to cause controlled destruction of the epidermis leading to exfoliation. Glycolic acid, salicylic acid and trichloroacetic acid are commonly used peeling agents for the treatment of active acne and superficial acne scars. CRYOTHERAPY: Cryoslush and cryopeel are used for the treatment of nodulocystic acne. Intralesional corticosteroids are indicated for the treatment of nodules, cysts and keloidal acne scars. Nonablative lasers and light therapy using Blue light, non ablative radiofrequency, Nd:YAG laser, IPL (Intense Pulsed Light), PDT (Photodynamic Therapy), pulse dye laser and light and heat energy machines have been used in recent years for the treatment of active inflammatory acne and superficial acne scars. Proper counseling is very important in the treatment of acne scars. Treatment depends on the type of acne scars; a patient may need more than one type of treatment. Subcision is a treatment to break the fibrotic strands that tether the scar to the underlying subcutaneous tissue, and is useful for rolling scars. Punch excision techniques such as punch excision, elevation and replacement are useful for depressed scars such as ice pick and boxcar scars. TCA chemical reconstruction of skin scars (CROSS) (Level C) is useful for ice pick scars. Resurfacing techniques include ablative methods (such as dermabrasion and laser resurfacing), and nonablative methods such as microdermabrasion and nonablative lasers. Ablative methods cause significant postoperative changes in the skin, are associated with significant healing time and should be performed by dermatosurgeons trained and experienced in the procedure. Fillers are useful for depressed scars. Proper case selection is very important in ensuring satisfactory results.
痤疮手术是指运用各种外科手术方法治疗痤疮后瘢痕,同时也作为活动性痤疮的辅助治疗手段。手术适用于活动性痤疮和痤疮后瘢痕。
任何皮肤科医生都可施行大多数痤疮手术技术,因为这些技术通常在毕业后学习。然而,某些技术,如磨皮术、激光换肤术、瘢痕修复术,需要在合适的培训中心接受特定的“实操”培训。
大多数痤疮手术可在医生的小型手术室进行。然而,全脸磨皮术和激光换肤术需要在医院环境的手术室进行。
手术治疗仅是药物治疗的辅助手段,药物治疗仍是主要治疗方法。粉刺挤压术是用粉刺挤压器施加简单机械压力,以挤出堵塞的毛囊皮脂腺内容物的过程。浅表化学剥脱术是将化学药剂涂抹于皮肤,从而可控地破坏表皮导致剥脱的过程。乙醇酸、水杨酸和三氯乙酸是常用于治疗活动性痤疮和浅表痤疮瘢痕的剥脱剂。
冷冻糊剂和冷冻剥脱术用于治疗结节囊肿性痤疮。皮损内注射皮质类固醇用于治疗结节、囊肿和瘢痕疙瘩性痤疮瘢痕。近年来,非剥脱性激光和蓝光光疗、非剥脱性射频、钕:钇铝石榴石激光、强脉冲光(IPL)、光动力疗法(PDT)、脉冲染料激光以及光热能量机器已用于治疗活动性炎性痤疮和浅表痤疮瘢痕。在痤疮瘢痕治疗中,恰当的咨询非常重要。治疗取决于痤疮瘢痕的类型;患者可能需要不止一种治疗方法。皮下分离术是一种破坏将瘢痕与下方皮下组织相连的纤维化条索的治疗方法,对滚轮状瘢痕有效。打孔切除技术,如打孔切除、抬高和置换,对冰锥样和箱车型等凹陷性瘢痕有效。三氯乙酸皮肤瘢痕化学重建术(CROSS)(C级)对冰锥样瘢痕有效。换肤技术包括剥脱性方法(如磨皮术和激光换肤术)以及非剥脱性方法,如微晶磨皮术和非剥脱性激光。剥脱性方法会导致皮肤术后出现显著变化,愈合时间长,应由接受过该手术培训且经验丰富的皮肤外科医生施行。填充剂对凹陷性瘢痕有效。恰当的病例选择对确保满意疗效非常重要。
