Abstract
In Japan, the majority of surgical cases of deviated nasal septum are treated via Killian's submucosal incision technique. With this method, however, incision is made directly over the septal cartilage and the caudal end is not exposed, therefore the deformity around the caudal end cannot be corrected. It has been believed that, in Japan, few patients with nasal obstruction have stenosis in the nasal valve area, but some cases do exist. We treated the nasal septum deviation of such cases via the maxillapremaxilla approach as described by Cottle. With this method, we could obtain good visualization of the nasal septum structure and correct the septum deformity around the nasal valve. This method is also applicable to difficult cases such as traumatic deformity of the nasal septum and a second approach after surgical failure.
