Lipofilling in Post-Treatment Oral Dysfunction in Head and Neck Cancer Patients

Lipofilling is a new treatment option for head- and neck cancer patients who suffer from chronic and severe (chemo-) radiation or surgery-related swallowing problems. Lipofilling is a technique of autologous grafting in which living fat cells are transplanted from one location to another in the same patient. In the case of head and neck cancer patients, volume loss or muscle atrophy of the tongue or pharyngeal musculature caused by the treatment may result in oropharyngeal dysfunction. Firstly, intensive swallowing therapy will be given, but if that offers no further improvement and the functional problems persist, lipofilling can be considered. By transplantation of autologous adipose tissue, the functional outcomes might improve by compensating the existing tissue defects or tissue loss. Only a few studies have been published which evaluated the effectiveness of this new treatment option. The results of those studies show that the lipofilling technique seems safe and of potential value for improving swallowing function in some of the included patients with chronic and severe dysphagia after surgery and/or (chemo-) radiation therapy for head and neck cancer. The lipofilling procedure will be described in detail as well as the clinical implications.
