Total or subtotal glossectomy with laryngeal preservation: a national study of 29 patients.

Total glossectomy remains a controversial procedure as it often leads to notorious sequalae in swallowing and speaking functions. Disease entities indicating total glossectomy tend to have poor prognosis. We evaluated whether this type of surgery can be concidered justified based on our national series. We reviewed all total and subtotal glossectomies with laryngeal preservation performed in Finland between 2005 and 2014 in terms of overall survival (OS), disease-specific survival (DSS), locoregional control (LRC), and functional outcome as assessed by gastric tube or tracheostomy dependence and ability to produce intelligible speech. Of the 29 eligible patients, 15 had undergone total and 14 subtotal glossectomy with curative intent. In eight patients, total/subtotal glossectomy was performed as salvage procedure after the previous treatment. One-year estimates for OS, DSS, and LRC were 48, 59, and 66%, and corresponding 3-year estimates were 31, 46, and 46%, respectively. The gastrostomy and tracheostomy dependence rates at 1 year after operation were 77 and 15%, respectively. Fifty-nine percent of the patients were assessed to be able to communicate verbally. As in most other published studies, we found unsatisfactory survival figures after subtotal or total glossectomy and most patients remained dependent on gastrostomy tube. This surgery is, however, presumably the best and often only chance for cure in a selective patient population, and according to our opinion, it is indicated as a primary or salvage treatment provided that the reconstruction is planned optimally to guarantee a reasonable quality of life after surgery.
