Objective: Correction of the caudal septum deviation is the most difficult part of the septoplasty and a common cause of revision septoplasty. The purpose of this study was to present authors' preliminary results in the treatment of patients with caudal septal deviation using the septal cartilage traction suture technique. Study Design: Prospective, single center, observational study. Materials and Methods: Sixty-seven patients with a caudal septal deviation underwent septal cartilage traction suture technique with endonasal septoplasty. After removal of excessive caudal cartilage, the caudal L-strut was sutured at two or more points using 5-0 Vicryl on the modified Killian incision site. Subjective outcomes using visual analog scales (VAS) and Nasal Obstruction Symptom Evaluation (NOSE) scale, objective endoscopic examination, and acoustic rhinometry data were assessed. Results: There was significant symptomatic improvement in the VAS and NOSE scale at 1, 3, and 6 months postsurgery. Complete correction in the endoscopy was observed in the 91.0% of patients at 3 months postsurgery. The results of acoustic rhinometry increased from 0.3 and 4.3 preoperatively to 0.7 and 7.7 at 3 months postoperatively. Furthermore, no patient experienced septal hematoma, septal perforation, and loss of nasal tip support at 6 months follow-up. Conclusions: The septal cartilage traction suture technique obtained significant improvement in subjective and objective outcomes in patients with caudal septal deviation. This technique is a simple, safe, and effective method to treat caudal septal deviation.

Background and ObjectivesThe American Joint Committee on Cancer (AJCC) staging system 8th Edition has stated that gross extrathyroid extension (ETE) is more important than microscopic ETE, and that it plays an important factor in the classification of T stages. Therefore, the prediction of gross ETE before surgery is important in establishing the clinical stage and determining the surgical extent. However, there are few studies predicting gross ETE using preoperative ultrasonography (US). The purpose of this study is to predict the gross ETE of papillary thyroid carcinoma (PTC) using preoperative US. Subjects and Method The preoperative US findings of 688 patients with PTC were compared with gross ETE confirmed during the surgery. The efficacy of preoperative US was statistically analyzed. Results A total of 70 (10%) patients were confirmed of their gross ETE. Thyroid tumors were classified into three groups (isolation, capsular contact, and capsular protrusion) according to their relationship with capsules, and evaluated using the preoperative US. There was a significant difference in gross ETE between groups (p<0.001). The thyroid tumor that came into contact with the capsule or protruded in the anterior region showed a difference between the capsular contact and capsular protrusion groups (p<0.001), whereas those came into contact with the capsule or protruded in the posterior region showed no significant difference between the two groups (p=0.187). There was no difference in the degree of protrusion (<25%, 25-50%, ≥50%) in the capsular protrusion group (p=0.868), but the difference in tumor size was significant (p<0.001). Conclusion Preoperative US is a useful tool for predicting gross ETE and is more predictable when the thyroid tumor is located anteriorly.
