Abstract

<p>Septoplasty using a hemitransfixion approach is an effective treatment for caudal septum deviation. The idea is to expose the caudal end of the nasal septal cartilage and adjust the cartilage to an appropriate shape and length. This method is useful; however, a delicate and careful technique is required to adjust the L-strut, which plays an important role in the strength of the nasal structure. The Modified Cutting and Suture Technique (MCAST) is a method for adjusting and refixing nasal septal cartilage, and is convenient and useful because it does not require transection of the anterior nasal spine or a septal batten graft. In this study, we investigated the usefulness of this procedure in 9 cases. CT examinations before and after surgery showed a significantly improved nasal cavity area ratio in all cases. There was also a significant improvement in the subjective symptom score. As an evaluation of external nasal deformity, a comparison of the nasolabial angle on CT before and after surgery showed no significant changes. These results suggest that MCAST is a simple and useful method for the hemitransfixion approach.</p>
