A Case of Large Septal Perforation Repair Using Inferior Based Contra-Lateral Nasal Floor Flap, a New Surgical Technique for Large Septal Perforation.

ABSTRACT A nasal septal perforation is a defect of cartilage, bone, or mucosa of nasal septum, which is caused by previous septal surgery, trauma, chemicals, inflammatory disease, or drugs. If conservative managements, such as nasal saline irrigation or ointments, are not effective, surgical treatment can be considered. Various methods for the reconstruction of nasal septal perforation were reported, such as local flaps, free flaps, autografts, allografts, or xenografts. However, there is no standardized method due to low success rate and high recurrence rate, especially in large perforations. The authors report a successful repair case of large anteroinferior nasal septal perforation, using inferior based contralateral nasal floor flap. The authors believe that our method is an effective way to repair large nasal septal perforation and to minimalize donor site morbidity, without using other allografts.
