Clinical application of supraclavicular fasciocutaneous island flap in the repair of tracheal defects / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the clinical application of supraclavicular fasciocutaneous island flap (SIF) in the repair of tracheal defect. Methods: From May 2016 to March 2021, the clinical data of 10 patients (8 males,2 females,aged 27-73 years old) were retrospectively analyzed who underwent repair surgery with SIF for trachea defects after resection of cervical or thoracic tumors, including 2 cases of laryngotracheal adenoid cystic carcinoma, 2 cases of laryngeal carcinoma, 3 cases of esophageal carcinoma, 2 cases of thyroid carcinoma and one case of parathyroid carcinoma. All of the primary tumors were at T4. The outcomes of 10 cases with tracheal defect repaired by SIF were evaluated. Results: The areas of the SIF were (3-7) cm × (6-10) cm, the thicknesses of the flaps were 8-11 mm, and the lengths of the pedicles were 10-15 cm. The blood supply of the SIF came from the transverse carotid artery. The skin defects of the donor areas of the shoulders were directly closed. After 1-60 months of follow-up, all the flaps survived. The flaps, tracheas as well as shoulder wounds healed well. Conclusion: The SIF is suitable for the repair of tracheal defects. It has perfect thickness compatible with the trachea. The technique is simple and microsurgical technique is not needed, with a good application prospect.

Prognostic analysis of 76 cases with adenoid cystic carcinoma in salivary gland / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the prognosis of adenoid cystic carcinoma (ACC) in salivary gland and its influencing factors.</p><p><b>METHODS</b>Clinical and following-up data of 76 patients with ACC in salivary glands were reviewed. Major gland tumors represented 35.5% whereas minor gland tumors comprised 64.5% of the cohort, with 8 cases (10.5%) in stage I, 23 (30.3%) in stage II, 18 (23.7%) in stage III and 27(35.5%) in stage IV. Survival rates were calculated by Kaplan-Merier method. Cumulative survival curves were evaluated using the Log-rank test. Multivariate analysis was performed by Cox proportional hazard model.</p><p><b>RESULTS</b>The regional recurrence rate was 28.9% and distant metastasis rate was 21.1%. The overall 5-year survival rate, tumor-free survival rate and tumor-related survival rate were 73.7%, 61.8% and 74.9% respectively. The overall 10-year survival rate, tumor-free survival rate and tumor-related survival rate were 48.2%, 39.8% and 56.2% respectively. Univariate survival analysis showed pathological type, clinical stage and perineural invasion were relevant to the prognosis of ACC and multivariate analysis showed they were the independent prognostic factors of ACC in salivary gland.</p><p><b>CONCLUSIONS</b>Clinical stage, pathological type and perineural invasion were the independent prognostic factors for adenoid cystic carcinoma in salivary gland. Surgery was the first choice for the treatment of adenoid cystic carcinoma in salivary gland, and postoperative radiotherapy may prolong the tumor-free survival time of patients in stage III and IV.</p>
