Treatment of N in the upper maxillary tumors.

From 2002 to 2008, 86 patients have undergone surgical treatment of malignant upper maxillary tumors at the Maxillo-Facial Surgery Department, Tor Vergata University, Rome. All the N-positive patients at the time of the T therapy have undergone lymph node surgical emptying. In 6 patients, a laterocervical emptying was performed when laterocervical metastases were found. In the remaining 68 patients, with no evidence of N, we did not perform laterocervical emptying. We found in our patients a high percentage of cervical metastasis in T2 squamous cell carcinoma of the maxilla (32.1%). In this article, the authors present the results of their experience in treating N in upper maxillary tumors. This research study highlights some important aspects that have to be considered. Squamous cell carcinoma of the maxilla extending to the oral cavity (T1-T2) shows a higher laterocervical lymphophily than the superoposterior ones (T3-T4). Presence or appearance of lymph node metastases is a high-malignancy index, with a subsequently very negative prognosis. Considering the large percentage of cervical recurrences in T1-T2 squamous cell carcinoma of the maxilla that spread up in the hard palate mucosa and upper gum and the consequently high morbidity, performing a prophylactic laterocervical emptying in these patients could be advisable. Even in the recent literature, we found opinion in favor of this behavior.
