Methods From September 2003 to August 2013, the records of 16 patients with a history of postoperative arytenoid dislocation were reviewed. Patients matched in terms of date and type of procedures were chosen as the controls(n=16). Recorded data for all patients were demographics, smoking status, alcoholic status, preoperative physical status, airway evaluation, intubation procedures, preoperative laboratory test results, anesthetic consumption and intensive care unit stay. For arytenoid dislocation cases, we further analyzed the incidences of the left and right arytenoid dislocation, and the outcomes of surgical repair and conservative treatment. Categorical variables were presented as frequencies and percentages, and were compared using the chi-squared test. Continuous variables were expressed as means±SD and compared using the Student's unpaired t-test. To determine the predictors of arytenoid dislocation, a logistic regression model was used for multivariate analysis. Results Sixteen patients with postoperative arytenoid dislocation were enrolled, with a median age of 52 years. Most postoperative arytenoid dislocation patients(15/16, 93.75%) received surgical repair, except one patient who recovered after conservative treatment. None of the postoperative arytenoid dislocation patients were smokers. Red blood cell(P=0.044) and hemoglobin(P=0.031) levels were significantly lower among arytenoid dislocation cases compared with the controls. Conclusions Non-smoking and anemic patients may be susceptible to postoperative arytenoid dislocation. However, neither of them was independent risk factor for postoperative arytenoid dislocation.展开更多

The anatomical and anesthetic causes of this complication were studied restrospectively, and the methods of treatment were discussed. The result showed that the incidence of arytenoid dislocation was about 0. 09% (5/5 826). Hoarseness, dysphonia and difficulty in feeding were the prevalent symptoms, and poor mobili- ty of the vocal fold was the most common sign. The treatment included closed reduction of the displaced arytenoid under local anesthesia, steroid and physical therapy. The possible causes of arytenoid dislocation were summarized as follows: (1) trauma produced by the blade tip of laryngoscope, (2) the use of stylet, (3) overstretching of aryepiglottic fold and vocal cord during laryngoscopy and intubation, and (4) cough- ing and movement of the endotracheal tube on the larynx during the endotracheal tube in place. It was sug- gested that correct technique and gentle manipulation during intubation could reduce the incidence of the complication. Timely postoperative follow-up and early reduction of arytenoid cartilage should be empha-sized in the diagnosis and treatment of the complication.展开更多

Methods: We retrospectively re-viewed 48 patients with advanced laryngeal cancer (T3 or T4 on the primary site) treated by subtotal laryngec-tomy with preservation of monoarytenoid cartilage to reconstruct laryngeal function. Eighteen of them under-went neck dissection. Ipsilateral recurrent laryngeal nerve was preserved during this surgery. The cricoid cartilage was anastomosed to hypopharynx accordingly. Results: The overall 3- and 5-year survival rates were 81.25% (39/45) and 66% 67% (32/48), respectively. All patients had good phonation and swallowing function after surgery. Decannulation rate was 93. 75%. Conclusion: Subtotal laryngectomy with preserva-tion of monoarytenoid cartilage is satisfactory for treatment of elected advanced laryngeal cancers. The effect of this surgery is more satisfactory than that of the near-total laryngectomy (Pearson''s technic).展开更多
