The Outcome of the Correction of Anterior Vocal Cord Web by Flap Technique using Real Anterior Vocal Cord Base in Frontolateral Laryngectomy in Patients with Glottis Cancer

Background: Due to the lack of interventional studies on the change in sound quality of patients suffering laryngeal cancer after partial frontolateral laryngectomy and anterior TVC reconstruction using laser, we aimed to assess the extent of changes in sound quality after correction of anterior vocal cord web by flap technique using TVC base in frontolateral laryngectomy by voice handicap index (VHI) and voice analysis factors in patients with glottic cancer.Methods: In this interventional case series study, ۱۵ consecutive patients with laryngeal carcinoma undergoing partial frontolateral laryngectomy by laser at Hazrat Rasool Akram Hospital between ۲۰۱۷ and ۲۰۱۹ suffering anterior adhesion of vocal cords were entered in final evaluation. All patients underwent microlaryngeal flap surgery to improve sound quality. The anterior web of larynx was dissected with a ۶-watt super pulse CO۲ laser. Results: The vocal analysis before and after operation showed a significantly improving vocal quality parameters including Habitual F۰, Jitter, Shimmer, Tremor F۰, Mean F۰, SD F۰, Max F۰, NNE, HNR, SNR, Ratio, Hoarse score, Harsh, and breathy after surgery as compared to before that. The scores for three emotional, physical, and functional components of VHI all significantly improved after operation. Conclusion: The correction of anterior vocal cord web by flap technique using TVC base in frontolateral laryngectomy leads to favorable outcome regarding vocal quality and voice performance in patients suffering glottic cancer
