Rhinoplasty is the most common aesthetic surgical procedure in Iran. Dorsal bony and cartilaginous structures of the nose play an important role in nasal esthetics and function. Manipulation of nasal dorsum is one of the cardinal procedures during rhinoplasty operation. Some cases of primary rhinoplasty lead to various post-operative nasal imperfections. One of the most common imperfections is dorsal nasal spur which can cause dorsal irregularities. The accurate rate of imperfections relates to some factors like the surgeon's experience and his/her precision, and appropriate post-operative patient care. Alomost 15%of revision or secondary surgical manipulations are acceptable for an experienced plastic surgeon. Most of the revision rhinoplasties are due to minor deformities in nasal dorsum like cartilaginous spur or mild focal depression. We have introduced an innovative device "Closed Nasal Chondrotome" that can ease the procedure for treating of minor nasal dorsal deformities. we propose the use of closed nasal chondrotome for mild dorsal spurs and have presented the effectiveness of this device in one patient. This simple but very effective instrument can be an alternative for a revision rhinoplasty procedure in the operating room to an outpatient procedure with local anesthesia. This method has been used in one patient with the satisfactory result, permitting corrections of minor cartilaginous excess deformities, with a less invasive procedure.
隆鼻术是伊朗最常见的美容外科手术。鼻背的骨性和软骨结构在鼻美学和功能中起着重要作用。鼻背的处理是隆鼻手术中的主要步骤之一。一些初次隆鼻病例会导致各种术后鼻部缺陷。最常见的缺陷之一是鼻背棘，它会导致鼻背不规则。缺陷的准确发生率与一些因素有关，如外科医生的经验和操作精度以及适当的术后患者护理。对于经验丰富的整形外科医生来说，几乎15%的修复或二次手术操作是可以接受的。大多数修复隆鼻手术是由于鼻背的轻微畸形，如软骨棘或轻度局灶性凹陷。我们推出了一种创新设备“闭合式鼻软骨刀”，它可以简化治疗轻微鼻背畸形的手术过程。我们建议使用闭合式鼻软骨刀治疗轻度鼻背棘，并展示了该设备在一名患者中的有效性。这种简单但非常有效的器械可以将手术室中的修复隆鼻手术替代为局部麻醉下的门诊手术。该方法已应用于一名患者，效果令人满意，能够在侵入性较小的情况下矫正轻微的软骨过度畸形。
