Submandibular approach and use of the harmonic instrument in lateral oral cavity and oropharyngeal oncologic surgery.

Le résumé fourni par la source

The approach to the surgical treatment of lateral oral cavity and oro-pharyngeal cancer has undergone many changes over the years, passing from a demolitive approach involving segmental resectioning of the mandible to a conservative approach with temporary mandibulotomy. The complications resulting from these two different approaches invited further review of the various indications related to them. The present report considers, through a retrospective analysis, whether the sub-mandibular approach, which envisages the use of the harmonic instrument, is an oncologically correct alternative and whether it actually reduces the number of early and late complications. From 2003 to 2009, 259 patients underwent surgery for lateral oral cavity and oro-pharyngeal cancer. A sub-mandibular approach was used in 163 patients, and a conservative trans-mandibular approach in 12. The results showed that the number of late complications and T recurrences was significantly lower in those patients in whom the sub-mandibular approach was carried out. There was no difference in the microscopic examination of the resection margins. The use of the harmonic instrument made it possible to perform "en bloc" (T+N) operations working in narrow spaces with less intra-operative bleeding, which contributed to adequate oncological radicality.
