Abstract:
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.
