Retromolar trigone--oropharynx junction maligns tumor surgery: transmandibular versus oral approach.

AIM: This study proposes a new approach to a borderline pathology between Otorhinolaryngology (E.N.T.) and Oral and Maxillofacial Surgery (O.M.F.), the malignant tumors of the oropharyngeal and retromolar trigone junction.

MATERIAL AND

METHODS

52 cases of retromolar trigone and oropharynx malign tumors were solved in the ENT department of "St. Spiridon" Universitary Hospital Iasi between 2012 and 2014. All patients were males, 35-64 years old, in different TNM stages. The novelty stands in the multidisciplinary approach, with an operating team consisting of both E.N.T. and O.M.F. surgeons, which joined their knowledge and expertise in order to offer a better treatment for the patient. Human Papilloma Virus (HPV) infection has been known as a trigger factor in head and neck cancers. The connection between HPV infection and malignant tumors of the oropharyngeal--retromolar trigone junction, together with the other traditional risk factors (smoking, alcohol, stress and sexual behavior) are involved in the therapeutic protocols, improving the life quality, the survival rate and reducing the treatment costs.

RESULTS AND DISCUSSION: Excision of the malignant tumors at the level of the junction between the oropharynx and retromolar trigone often requires repairing the tissular defects that remain using different flaps. Postsurgical mecanotherapy (physiotherapy) under the surveillance of an experienced physiotherapist is also needed for a complete recovery.

CONCLUSIONS

This therapeutical protocol aims to assure a better life quality for the patients, with a faster postsurgical recovery and social reinsertion by reducing the healing time of the areas affected by inflammation and necrosis generated by the neoplastic process.
