The correction of deviated nose has been widely performed in the field of plastic surgery. But the recurrences after operation have been quite frequent. Even though exact anatomical correction through open rhinoplasty procedure made the recurrence rate decreased, complete prevention of recurrence was very difficult because the cartilaginous portion of nasal skeleton tends to return to previous deviated state and the subcutaneous scar of the soft tissue distort the nasal skeleton. For the prevention of nasal deviation after corrective rhinoplasty, we used conventional silastic nasal stents for 6 months after corrective rhinoplasty in 50 patients from February 1991 to September 1996. We experienced only 2 cases of recurrent deviations and 2 cases of nasal obstructions. By close observation of the CT scan and simple X-ray films of the patients who had undergone recurrent deviation with the conventional silastic nasal stents, we concluded the conventional nasal stents were inappropriately short to prevent the recurrent nasal deviation. From October 1996 to September 1999, we used the customized silastic nasal stents in 19 patients which were long enough(mean length: 3.5 cm) to reach the perpendicular plate of ethmoid, enabling to support the full length of the cartilaginous dorsum and septum and well fixed to individual patients' nostril, instead of using the conventional nasal stents which were too short to support the whole cartilaginous portion (mean length: 2.0 cm). We experienced satisfactory results except only one mild nasal deviation. By using the customized silastic nasal stent, the recurrence of nasal deviation has been minimized without any discomfort and nasal cavity obliteration, no skin and mucosal ulceration has occurred, and the postoperative nasal obstruction has been markedly improved compared to the conventional nasal stent.
