To evaluate the degree of dysphagia in patients before and after total laryngectomy using the Performance Status Scale for Head and Neck Cancer Patients (PSS) and to determine the effects of post-operative radiation therapy, neck dissection, and pharyngoesophageal spasm on PSS scores.
We performed a controlled, prospective study at a tertiary referral university hospital. Twenty consecutive patients undergoing laryngectomy were included. Patients were followed for at least two years post-operative, without evidence of local, regional, or distant disease. Only patients with squamous cell carcinoma limited to the endolarynx requiring total laryngectomy with or without elective neck dissection for surgical management of cancer and with no pre-operative treatment were included. Dysphagia was evaluated by PSS prior to surgery and again two years postoperatively with an emphasis on eating in public and normalcy of diet domains. Video fluoroscopic evaluation of swallowing was performed one year after treatment.
The relative number of patients with low mean scores in PSS (i.e. usually swallow paste of fluid food in presence of some selected persons or alone; < or = 50) increased after total laryngectomy (p = 0.04). Patients with lower scores reported more frequent spasm of the pharyngoesophageal segment (p = 0.005). Mean scores of both domains decreased after surgery (p < 0.05).
Eating in public and normalcy of diet scores decreased in 50% of patients after total laryngectomy.

    ABSTRACT: Introduction: Total laryngectomy creates deglutition disorders and causes a decrease in quality of life Aim: To describe the impact of swallowing and quality of life of patients after total laryngectomy. Method: A case series study. Patients completed a Swallowing and Quality of Life questionnaire composed of 44 questions assessing 11 domains related to quality of life (burden, eating duration, eating desire, frequency of symptoms, food selection, communication, fear, mental health, social functioning, sleep, and fatigue). The analysis was performed using descriptive statistics, including measures of central tendency and variability. Results: The sample comprised 15 patients who underwent total laryngectomy and adjuvant radiotherapy. Of these, 66.7% classified their health as good and 73% reported no restrictions on food consistency. The domains "communication" and "fear" represented severe impact and "eating duration" represented moderate impact on quality of life. The items with lower scores were: longer time to eat than others (domain "eating duration"), cough and cough to remove the liquid or food of the mouth when they are stopped (domain "symptom frequency"), difficulties in understanding (domain "communication") and fear of choking and having pneumonia (domain "fear"). Conclusion: After total laryngectomy, patients report that swallowing issues have moderate to severe impact in "communication," "fear," and "eating duration" domains.

    ABSTRACT: Purpose of review: Total laryngectomy rehabilitation (TLR) in Europe is not uniform, with quite some differences in approach and infrastructure between various countries. In, for example, the Netherlands, Switzerland, Scandinavia, and more recently also in the UK, head and neck cancer (HNC) treatment and rehabilitation shows a high level of centralization in dedicated HNC centres. In other European countries, the level of centralization is lower, with more patients treated in low-volume hospitals. This article focusses on the situation in the Netherlands and, where applicable, will discuss the regional variations in Europe. Recent findings: Prosthetic surgical voice restoration (PSVR) presently is the method of choice in Europe, and use of oesophageal and electrolarynx voice has moved to the background. In most European countries (except the UK and Ireland), PSVR is physician driven, with an indispensable role for speech-language pathologists and increasingly for oncology nurses. Indwelling voice prostheses are mostly preferred, also because these devices can be implanted at the time of trachea-oesophageal puncture. Pulmonary rehabilitation is achieved with heat and moisture exchangers, which, based on extensive clinical and basic physiology research, are considered an obligatory therapy measure. In addition to PSVR, also issues such as smoking cessation, dysphagia/swallowing rehabilitation, and olfaction/taste rehabilitation are discussed. Especially, the latter has shown great progress over the last decade and is another example of increasing implementation of evidence-based practice in TLR. Summary: TLR has shown considerable progress over the last decades, and through the intensified collaboration between all clinicians involved, significantly has improved vocal, pulmonary, and olfactory rehabilitation after total laryngectomy.

    ABSTRACT: The purpose of this study is to compare health-related quality of life (HRQoL) and emotional distress among diverse cancer survivors who had completed all treatment within the previous year. A convenience sample of 353 cancers survivors (lung, head and neck, breast and prostate cancers) were recruited to complete a survey, which consisted of (i) Hospital Anxiety and Depression Scales; (ii) Chinese version of the Functional Assessment of Cancer Therapy-General version; and (iii) demographic and clinical data. The HRQoL scores were similar among the four types of survivors. Mild anxiety and depression levels were reported, but no significant difference was noted. Younger females with financial burdens and uncertain prognosis were particularly associated with HRQoL and emotional distress. Further studies are essential to identify specific problems that cancer patients experience after cancer diagnosis that might lead to the early detection of those most at risk of ongoing problems.
