Auricular cartilage is soft and plastic at birth, so that congenital auricular deformities can easily be corrected nonsurgically in the early neonatal period. However, as the infant grows older, the flexibility of the auricle decreases. Alar cartilage exhibits the same elasticity as auricular cartilage in the early neonate. When a cleft lip is repaired, typically when the infant is about 3 months of age, it becomes difficult to correct the nasal deformity without surgical intervention. However, based on our experience, there is a fair possibility of correcting the cleft lip nasal deformity with a nonsurgical procedure in the early neonatal period. We performed cleft lip repair accompanied by nonsurgical correction of the nasal deformity in 44 neonates aged 2 to 7 days. A special retainer was placed in the affected nostril for 3 months. Following observation of 31 infants for 12 months or longer, their nasal shapes and symmetry were considered superior to those conventionally operated on at about 3 months of age. Except for one nasal infection, there were no complications.
耳廓软骨在出生时柔软且具有可塑性，因此先天性耳廓畸形在新生儿早期很容易通过非手术方法矫正。然而，随着婴儿长大，耳廓的柔韧性会降低。鼻翼软骨在新生儿早期表现出与耳廓软骨相同的弹性。当修复唇裂时，通常在婴儿约3个月大时进行，此时如果不进行手术干预，就很难矫正鼻畸形。然而，根据我们的经验，在新生儿早期通过非手术方法矫正唇裂鼻畸形有相当大的可能性。我们对44名年龄在2至7天的新生儿进行了唇裂修复并同时对鼻畸形进行非手术矫正。在患侧鼻孔放置一个特殊的固定器3个月。在对31名婴儿进行了12个月或更长时间的观察后，发现他们的鼻形和对称性优于那些大约在3个月大时接受传统手术的婴儿。除了一例鼻部感染外，没有其他并发症。
