Although there are usually multiple veins draining the nasal tip, division of the lateral nasal veins may result in an increase in the supratip edema. 鼻尖部虽有多条静脉引流，但截断外鼻静脉还是会导致鼻尖上区肿胀加重。
Dissection in the deep areolar plane will not ensure preservation of the lateral nasal veins that pass over the perichondrium of the middle nasal vault. 在深层网状组织平面的分离并不能保证沿中鼻拱软骨膜表面走行的外鼻静脉完整。
