Abstract

<p>Correction of caudal septum deviation requires surgical manipulation from the caudal side of the septum. In a case of concomitant external nasal deformity, an external method (i.e. – open septorhinoplasty) is selected, whereas in other cases, an endoscopic method (i.e. a hemitransfixion approach) is indicated. This type of nasal septal deviation is caused by an excessive cartilaginous nasal septum in relation to the bony septum. After the surgeon has separated the nasal septum cartilage from the anterior nasal spine (ANS) and trimmed the cartilage at the posterior nasal angle to ensure proper cartilage size, an anchoring suture is performed to reattach the cartilage and ANS. However suture manipulation is often difficult in the nasal endoscopic method due to the narrow surgical area. In this study, we compared the figure-8 suture and dual knot fixation (DKF) technique as methods of anchor suture for nasal endoscopic septoplasty. Our results show that DKF may be useful as a low-stress suture method for surgeons performing endonasal septoplasty.</p>
