Aims:
The aim was to correlate the incidence of metastasis to Level IIB of neck lymph nodes (LNs) for oral cavity carcinomas with the site, size, and histological grade of tumor.
Settings And Design:
Total 30 patients of either sex, with biopsy-proven oral squamous cell carcinoma of any site, size or histologic grade, but N0/N1 were taken for selective neck dissection (SND).
Materials And Methods:
Thirty patients who underwent SND for oral carcinoma were analyzed for the relation of the site, size, and histological grade of malignancy with metastatic involvement to Level IIB nodes. Level IIB nodes were dissected separately and sent for histopathological examination.
Statistical Analysis Used:
The data were entered in custom written software in Excel (MS office 2007, Windows XP) and the data were analyzed using statistical software STATA version 10.0. The statistical test used for the analysis of the result was Chi-square test. The critical level of statistical significance chosen was P < 0.05.
Results:
Only 2 of 30 patients (6.6%) had the involvement of Level IIB neck nodes. There was no relation between the site, size, and histologic grade of primary tumor with the metastasis to Level IIB. The Level IIA nodes were positive in both the positive cases of Level IIB.
Conclusions:
For tumors in oral cavity (N0/N1), while performing elective or therapeutic SND the dissection of Level IIB nodes could be omitted as it will provide significant decrease in operative time and also less of spinal accessory nerve trauma-related complications.
