    Abstract:
    BACKGROUND: Surgical correction of severe caudal deviation of nasal septum using an endonasal approach is challenging for surgeons. Among cases of severe caudal septal deflection, fracture lines along the horizontal direction are occasionally encountered during the surgery. We devised a simple and efficient technique called "triangular excision and submucosal rejoining" to address this kind of deformity. METHODS: A total of 9 patients with severe caudal septal deflection underwent "triangular excision and submucosal rejoining." After the removal of the deformed posteroinferior portion of the quadrangular cartilage, 2 incision lines were made on the remaining caudal septum, starting from a point at the most anterior portion of the fracture line and diverging posteriorly above and below the fracture line. After removing a triangular cartilaginous piece, the upper and lower remaining cartilage segments were approximated using a single or 2 simple interrupted sutures. Sutures exiting the mucosa were re-entered from the exit point so that all the sutures were buried underneath the mucosa while the mucosal flap was elevated only unilaterally. RESULTS: This technique was effective in all cases. Septal batten grafts were applied in 3 patients, in whom the remaining quadrangular cartilage was weak and thin. One patient showed a mildly recurred septal deviation, but the nasal cavities remained patent with no symptoms. Serious complications such as dorsal saddling or tip ptosis did not occur in any cases. CONCLUSION: "Triangular excision and submucosal rejoining" may be a safe and efficient septoplasty technique to correct a horizontally folded caudal septum.
