Abstract:
Objective:To analyze the acoustic characteristics of patients with hypopharyngeal cancer accompanied by vocal cord dysfunction. Methods:A retrospective analysis was conducted on the data of patients with hypopharyngeal cancer who were initially treated at The Second Affiliated Hospital of Xi'an Jiaotong University from January 2018 to April 2024. Patients who had completed electronic laryngoscopy, stroboscopic laryngoscopy, and voice analysis were selected from the data. Among them, patients with hypopharyngeal cancer who had unilateral vocal cord activity disorders were selected as the experimental group, while patients with symmetrical bilateral vocal cord activity were assigned to the control group. Then the clinical characteristics, the vocal parameters, and the stroboscopic laryngoscopy results of patients with hypopharyngeal cancer in the experimental group and the control group were analyzed and compared. Results:Compared with that in the control group, the proportion of lesions located on the inner wall of the piriform fossa in the experimental group increased（83.3% vs 53.8%）, and the difference was statistically significant（P<0.05）. There was no significant difference in vocal parameters such as SPL, Jitter, Shimmer, MPT, DSI, F0, sound intensity, electroglottic value and VHI between the experimental group and the control group（P>0.05）. However, the values of F0, Jitter, Shimmer and VHI in the experimental group were higher than those in the control group. In addition, in terms of the results of stroboscopic laryngoscopy, the proportion of glottic insufficiency（42.9% vs 18.8%） and asymmetric arytenoid cartilage（64.3% vs 0） in the experimental group was significantly higher than that in the control group（P<0.05）. However, the mucosal waves of the vocal cords on the affected side did not weaken in patients in both the experimental group and the control group. In the experimental group of 18 patients with hypopharyngeal cancer who received induction chemotherapy（nituzumab+nedaplatin+5-fluorouracil）, 13 of them had improved vocal cord activity（improvement rate of 72.2%）. Conclusion:Hypopharyngeal cancer in the medial wall of the pyriform fossa is more prone to vocal cord dysfunction, but vocal cord dysfunction has little effect on the vocal parameters of patients with hypopharyngeal cancer.
