Ear keloids continue to be a therapeutic challenge.
To evaluate the clinical success of a modified "oyster splint technique."
Ten patients with an ear keloid agreed to receive the compression therapy. After surgical removal, a compressive device made of acrylic resin was applied on top of a silicone gel sheet and patients were asked to wear the splint 23 hours a day for at least 8 months. If the scar showed a tendency to grow, corticosteroids were injected intralesionally. In addition to recurrence rate, other parameters and wearing times were obtained by an interview.
Two of 10 patients experienced a recurrence in a mean follow-up period of 18.2 months (range 4-44 months). The daily wearing time of the compression splint was critical for the success of the treatment (p = .022). The splint had to be worn at least 10 hours a day for a minimum of 8 months to prevent recurrence. However, the need for additional intralesional steroid injections was significantly lower in patients wearing the splint for more than 20 hours per day (p = .048). The splint treatment was painless for 80% of patients. The therapeutic result was given a median mark of 1.75 (1 = best, 6 = worst).
Although it requires considerable time and effort, the technique seems to be a promising therapy.
耳部瘢痕疙瘩仍然是一种治疗挑战。
评估改良“牡蛎夹板技术”的临床疗效。
10 名耳部瘢痕疙瘩患者同意接受压迫治疗。在手术切除后，在硅凝胶片上应用丙烯酸树脂制成的压缩装置，并要求患者每天佩戴夹板 23 小时，至少 8 个月。如果瘢痕有生长趋势，则进行皮损内注射皮质类固醇。除复发率外，还通过访谈获得其他参数和佩戴时间。
10 名患者中有 2 名在平均 18.2 个月（4-44 个月）的随访期内复发。压缩夹板的日佩戴时间对治疗的成功至关重要（p =.022）。为了防止复发，夹板必须每天佩戴至少 10 小时，至少 8 个月。然而，每天佩戴夹板超过 20 小时的患者需要额外皮损内注射皮质类固醇的次数明显更低（p =.048）。80%的患者对夹板治疗无疼痛感。治疗效果的中位数评分为 1.75（1=最佳，6=最差）。
尽管需要相当多的时间和精力，但该技术似乎是一种有前途的治疗方法。
