儿童鼻外伤并不少见,其原因很多,粗略地讲随年龄的变化而不同。新生儿外伤:分娩前的某些外伤性损害(约占0.5%),如受到骨盆、双胎时胎儿的肢体长期压迫所致的外鼻畸形和中隔偏曲,均已在剖腹产术时被证实。在分娩期间,除器械操作(产钳损伤)医源性外伤外,暂时性的鼻部压扁经常发生。如鼻中隔前部脱位、整个外鼻锥体或尖部歪斜、鼻小柱塌下、鼻孔不对称约占2～23%,平均5～7%,Gray在2093例正常分娩中发现鼻中隔偏曲占4%,若在分娩最后阶段,时间延续15分钟以上的损伤占13%。认为1/3的鼻中隔脱位
It is not uncommon for children with nasal trauma to have many reasons, roughly speaking, that vary with age. Neonatal trauma: some traumatic injury before delivery (about 0.5%), such as pelvic, twin fetal limbs caused by long-term compression of nasal deformities and septal deviation, have been in caesarean section was Confirmed. During childbirth, temporary nasal squash often occurs in addition to iatrogenic trauma to instrumentation (forceps injury). If the nasal septum anterior dislocation, the entire outer nose cone or tip askew, collapse of the nasal columella, nasal asymmetry accounted for about 2 ~ 23%, an average of 5 to 7%, Gray in 2093 cases of normal delivery found nasal septum deviation 4%, if in the final stage of delivery, the damage lasting more than 15 minutes accounted for 13%. Think 1/3 of the nasal septum dislocation
