Herein, we describe the case of a 33-year-old woman with a rare 16-mm congenital midline upper lip fistula with a broad, cystic lumen. No connection with the oral cavity was observed. Congenital midline upper lip fistulas are not clearly associated with hereditary factors or sex. Sinus computed tomography revealed an inner ear malformation; however, no associations between external and inner ear malformations and upper lip fistulas have been reported. Because the developmental processes of the upper lip and inner ear are different, each develops independently, as in the current case. The standard treatment for congenital upper labial fistula is surgical excision. Shallow fistulas are often approached through a fusiform incision around the fistula. For deep fistulas, expanding the surgical field via a small skin incision is difficult, with a high possibility of a large incision. However, an incision through the oral mucosa minimises the incision size around the fistula.
在此，我们描述了一名33岁女性的病例，她患有罕见的16毫米先天性中线唇上瘘管，管腔宽大呈囊性。未观察到与口腔的连接。先天性中线唇上瘘管与遗传因素或性别无明显关联。鼻窦计算机断层扫描显示内耳畸形；然而，尚未有关于外耳和内耳畸形与唇上瘘管之间关联的报道。由于上唇和内耳的发育过程不同，如本例所示，它们各自独立发育。先天性唇上瘘管的标准治疗方法是手术切除。浅瘘管通常通过瘘管周围的梭形切口进行处理。对于深瘘管，通过小皮肤切口扩大手术视野困难，且大切口的可能性很高。然而，通过口腔黏膜切开可使瘘管周围的切口尺寸最小化。
