[Effect of four line tension relaxing for nasal deviation rectification under endoscope].

OBJECTIVE: To explore the effect of four line tension relaxing septorhinoplasty for nasal deviation complicated with the deformity of nasal septal cartilage under endoscope. METHODS: Seventeen patients with nasal septum deviation from December 2009 to April 2011 were included in this study. The patients were divided into different groups depending on different deformity of quadrangular cartilage. Different surgical methods were used according to different deviation of nasal septum. First, a C-shape or L-shape incision was made on one side of the nasal septum under endoscope, then the nasal septal cartilage was separated from the angle formed by two greater alar cartilages, perpendicular plate of the ethmoid bone, the junction of vomer and maxilla at the nasal crest, and the upper lateral cartilage, this procedure was applied to correct deviation of nasal septum and nasal pyramid by decompression, which was named four lines tension relaxing correction. RESULTS: Seventeen patients with nasal septal deviation obtained satisfied curative effect. Nasal deviation and deviation of nasal septum were all corrected, patients got better appearance and good nasal ventilation, no complication was observed. CONCLUSION: Nasal deviation complicated with the deformity of nasal septal cartilage could be completely corrected by only one septorhinoplasty operation--four lines tension relaxing correction.
