Abstract：
Congenital macrostomia is a rare congenital deformity that consists of an enlargement of the commissure of the mouth. The malformation may be unilateral or bilateral and has a polymorphic presentation. Various surgical techniques have been described to correct macrostomia, with only a few cases illustrating the expected results. The surgical repair must consider both esthetic as well as functional impacts for the patient. We here propose a technical note to refine and provide additional information for good achievement of \"Double Reversing Z-Plasty\" for correction of macrostomia. Our case series also reports good long-term functional and esthetic results obtained with this technique, especially in case of a minor cleft.
摘要：
先天性大口是一种罕见的先天性畸形，包括口腔连合的扩大。畸形可以是单侧或双侧的，并且具有多态表现。已经描述了各种手术技术来矫正巨大口症，只有少数案例说明了预期的结果。手术修复必须考虑对患者的美学和功能影响。我们在这里提出了一项技术说明，以完善并提供其他信息，以良好地实现“双重反向Z-Plasty”以矫正大口。我们的病例系列还报告了使用这种技术获得的良好的长期功能和美学结果，尤其是在有轻微裂口的情况下.
