Article Abstract
Objective: To investigate the cause of unilateral vocal cord paralysis in aged.
Method: Fifty-one patients with unilateral vocal cord paralysis in aged were retrospectively analyzed.
Result: The main cause of unilateral vocal cord paralysis in aged was malignant tumor.
Conclusion: Extralaryngeal malignant tumor should be greatly suspected in aged with unilateral vocal cord paralysis. When the cause could not be identified through systematic examination, the patient should be followed up regularly.

Efficacy of vocal fold injection of dedifferentiated fat cells in treating glottis closure insufficiency: Insights from a rat model of recurrent laryngeal nerve resection.

Glottic insufficiency results from impaired vocal fold contact, leading to a gap between the folds and manifesting as hoarseness and respiratory difficulties. Vocal folds injection is a commonly utilized therapeutic approach to rectify this gap by augmenting vocal folds volume; however, the optimal injectable material remains undetermined. Dedifferentiated fat cells (DFATs), derived from mature adipocytes, exhibit robust proliferative capacity and multipotency, establishing them as potential candidates for treating glottic insufficiency.
