[Analysis of relevant factors causing laryngeal stenosis after partial laryngectomy].

AbstractOBJECTIVE:
To investigate the clinical relevant factors causing laryngeal stenosis after partial laryngectomy.
METHODS:
A retrospective study was carried out to review the history clinical data from 138 patients of partial laryngectomy in the First Affiliated Hospital of Sun Yat-Sen University between January 1994 to October 2004. The clinical relevant factors causing laryngeal stenosis were included as follows: age, sex, TNM stage, tumor site, extension of thyroid cartilage defect, extension of larynx parenchyma defect, reconstruction method, laryngeal dilator, duration of using antibiotics, postoperative radiotherapy, lung infection, gastroesophageal reflux, diabetes. Multivariate stepwise logistic regression model was used for the analysis.
RESULTS:
Of 138 cases after partial laryngectomy, stenosis developed in 25 cases. The occurrence rate was 18.1%. In multivariate analysis, it was confirmed that the following factors correlated to laryngeal stenosis, i. e, extension of thyroid cartilage defect (chi2 = 4.323, P = 0.038), postoperative radiotherapy (chi2 = 6.002, P = 0.014), lung infection (chi2 = 4.220, P = 0.040), and gastroesophageal reflux (chi2 = 5.614, P = 0.018).
CONCLUSIONS:
The clinical relevant factors causing laryngeal stenosis after partial laryngectomy were multiple. Statistical analysis showed that extension of thyroid cartilage defect, postoperative radiotherapy, lung infection and gastroesophageal reflux were the risk factors which may cause laryngeal stenosis.
