교정비성형술 후 비개존성에 대한 평가

Acoustic rhinometry is a new, objective method to assess the geometry of the nasal cavity. The cross-sectional area and nasal volume of the nasal cavity as the function of the distance from nosepiece was obtained to evaluate the charateristics of the nasal obstruction. 38 patients with the deviated nose underwent the corrective rhinoplasty. The parameters such as the minimal cross-sectional area (MCA) and nasal volume (NV) of nasal cavity were measured before and after corrective rhhinoplasty. The results were as follows : 1) The scores of the Nasal Obstruction Symptom Evaluation (NOSE) scale was increased sigificantly after the date of surgery. 2) The MCA and NV was increased significantly on the narrow site. 3) The MCA and NV did not increase significantly on the wide site. Correction of the nasal septal deviation and exteranl bony nose at the corrective rhinoplasty caused the increase of the MCA and NV and the improvement of the nasal obstruction with statistical significace. In conclusion, acoustic rhinometry can be useful in evaluating the improvement of the nasal obstruction after the corrective rhinoplasty. (J Clinical Otolaryngol 2006;17:217–222)
