Swallowing function in patients with vertical hemipharyngolaryngectomy for hypopharyngeal squamous cell carcinoma.

BackgroundThe purpose of this study was to evaluate the long-term swallowing function in patients with vertical hemipharyngolaryngectomy (VHPL) for hypopharyngeal cancer. MethodsA retrospective review of 30 patients followed for more than 2 years with VHPL between 1998 and 2011 was performed. ResultsFive patients (16.7%) experienced gastrostomy tube placement, 4 patients (13%) had pharyngoesophageal stricture, and 13 patients (45%) had aspiration pneumonia. There was a significant difference in the fraction of gastrostomy tube placement among type II VHPL (35.7%), type I VHPL (0%), and type III VHPL (0%; p=.014). Gastrostomy tube dependence was significantly associated with flap size (larger than 70 cm(2); p=.043) and aspiration pneumonia (p=.009). A significant positive correlation was found between current smokers and aspiration pneumonia (p=.030). ConclusionType II VHPL, large flap reconstruction, and aspiration pneumonia had predictable values for gastrostomy tube dependence. Smoking status correlated with aspiration pneumonia. Better counseling and vigilance concerning swallowing difficulties may be possible. (c) 2015 Wiley Periodicals, Inc. Head Neck 38: 191-195, 2016
