In cases of locally advanced cancers involving the junction between the hypopharynx and cervical oesophagus, the curative surgical treatment is total circular laryngo-pharyngectomy with resection of the upper cervical oesophagus, coupled with modified radical neck dissection. Techniques used to re-establish the continuity of the digestive tract have been pectoral transposition flap, gastric pull-up, jejunum or colon transposition and free pedicled fascial-cutaneous flap reconstruction. Prosthetic reconstruction was thought of and used only as a temporary solution. In our clinic, we adapted the Montgomery oesophageal prosthesis as more than just a temporary solution and used it in 63 patients operated from 2004 to 2014 with advanced (stages III and IV) cancer involving most of the hypopharynx or extending towards the upper cervical oesophagus. Following total circular laryngo-pharyngectomy with bilateral modified radical neck dissection, prosthetic reconstruction was performed using the Montgomery oesophageal tube. Patients were followed up on, and their status was monitored. Favourable results encouraged the authors to further develop a new active prosthesis, with advanced design and materials that better mimic the anatomy and physiology of the replaced segment. Prosthetic reconstruction of the upper digestive tract following radical oncologic surgery is a viable option, with advantages compared to other laborious plastic techniques. The new active model is under development, hopefully offering soon a safe and more cost-effective alternative to the other techniques.

Head and neck malignancies represent the sixth most frequent type of cancer currently in worldwide statistics. Of these, oral and pharyngeal cancers have steadily increased, being linked with the increase in HPV infection pandemic. This rise is not due to one cause, but rather multiple factors such as lifestyle and sexual behavior pattern changes and globalization. Because of the anatomy of the oral cavity and oropharynx, the proper diagnosis is easily delayed, and patients present with advanced stage disease, which requires aggressive and extensive surgery along with neck dissection and chemoradiotherapy. Patients with advanced stage disease have a high recurrence risk with a low 5-year survival rate. Preventing the HPV infection is of course desirable, but right now, for adults which already are infected and have a higher risk of developing HPV-related neoplasias, as well as for our head and neck cancer patients, alternative treatment algorithms are necessary.
