Favourable swallowing outcomes after subtotal glossectomy with laryngeal suspension

Subtotal or total glossectomy for advanced tongue cancer has an adverse impact on swallowing. The purpose of this retrospective study was to analyse postoperative swallowing outcomes and to determine the ideal reconstruction method in these patients. The clinical and swallowing data of patients with tongue cancer who underwent subtotal glossectomy at the study institution between 2005 and 2019 were reviewed retrospectively. Data were available for 101 patients. The most common reconstruction method was a free rectus abdominis musculocutaneous flap (69 cases). The postoperative feeding tube dependency rate was 11.1% at discharge and 9.4% at 1 year. During the study period, laryngeal suspension and/or a cricopharyngeal myotomy was performed in 39 patients (38.6%), with 25 of these operations performed after 2017. Patients treated in 2017-2019 were significantly more able to take thin liquid (P < 0.001) and lost less weight (P = 0.015) compared to those treated in 2005-2016. Multivariate analysis of 61 patients who did not undergo laryngeal suspension and/or cricopharyngeal myotomy showed significant feeding tube dependency in those aged 65 years and older (P = 0.004). Thin liquid intake was significantly improved after subtotal glossectomy with laryngeal suspension, which led to better postoperative swallowing and improved quality of life.
