Whistle deformities are frequent sequelae after surgical correction of cleft lip, trauma, or tumor excision. The aim of this study was to examine the role of autologous free fat grafting in the reconstruction of whistle deformity.
Fifteen patients with whistle deformity were enrolled in this pilot study. The mean follow-up period was 19 months. Liposuction was done followed by the replantation of an average of 2.2 ml autologous fat per patient (range 0.7-4 ml). An overcorrection was performed in all patients.
All the patients showed improvements in whistle deformity. The mean resorption rate was 53% (range 30-80%). Three patients (20%) were not satisfied with the postoperative result. Six complications were assessed (4× feeling of pressure [27%], one hematoma [7%], one recurrent pain [7%]), but a major complication did not occur.
We also present a review of the literature with different techniques that were described in the last 20 years.
Autologous free fat graftings for reconstruction of whistle deformity represent a reliable method with a low complication rate. However, the resorption rate is unpredictable. If necessary, several autologous fat transplantations should be conducted at an interval of at least 6 months.
口哨畸形是唇裂手术矫正、外伤或肿瘤切除术后常见的后遗症。本研究的目的是探讨自体游离脂肪移植在口哨畸形重建中的作用。
15例口哨畸形患者纳入本初步研究。平均随访期为19个月。先进行抽脂，然后每位患者平均再植2.2毫升自体脂肪（范围为0.7 - 4毫升）。所有患者均进行了过度矫正。
所有患者的口哨畸形均有改善。平均吸收率为53%（范围为30% - 80%）。3例患者（20%）对术后结果不满意。评估出6例并发症（4例有压迫感[27%]，1例血肿[7%]，1例复发性疼痛[7%]），但未发生严重并发症。
我们还对过去20年中描述的不同技术进行了文献综述。
自体游离脂肪移植用于口哨畸形重建是一种可靠的方法，并发症发生率低。然而，吸收率不可预测。如有必要，应至少间隔6个月进行多次自体脂肪移植。
