In all these 8 patients, reconstruction was done using nasolabial flap in 1 patient, buccal pad of fat in 2 patients, masseter flap in 1 patient and forehead flap in 4 patients.

<p class="abstract"><strong>Background:</strong> Oral cancer is the sixth most common cancer in the world and is largely preventable.

Elective Neck Dissection

Early stage oral cavity squamous cell carcinoma (OCSCC) has a significant risk of subclinical nodal metastases, which is the strongest independent prognostic factor for regional recurrence and survival. However current preoperative imaging modalities are unable to identify patients with micrometastases, and an observation strategy has been associated with inferior outcomes when compared to an elective neck dissection. Sentinel lymph node biopsy provides a safe and accurate staging procedure to select the patients who benefit from an elective neck dissection, while avoiding unnecessary surgery in the patients who are node negative. There is recent Level II evidence demonstrating equivalent oncological outcomes when compared with elective neck dissection. However, a multidisciplinary approach is required including reliable mapping of the sentinel lymph node, precise surgical technique and comprehensive histopathological analysis to ensure accurate results are obtained.

Abstract Background Lymph node yield is an important prognostic factor in head and neck squamous cell carcinoma. Variability in neck dissection sampling techniques has not been studied as a determinant of lymph node yield. Methods This retrospective study used lymph node yield and average nodes per level to compare level-by-level and en bloc neck dissection sampling methods, in primary head and neck squamous cell carcinoma cases operated between March 2017 and February 2020. Results From 123 patients, 182 neck dissections were analysed, of which 133 were selective and the rest were comprehensive: 55 had level-by-level sampling and 127 had undergone en bloc dissection. The level-by-level method yielded more nodes in all neck dissections combined (20 vs 17; p = 0.097), but the difference was significant only for the subcohort of selective neck dissection (18.5 vs 15; p = 0.011). However, the gain in average nodes per level achieved by level-by-level sampling was significant in both groups (4.2 vs 3.33 and 4.4 vs 3, respectively; both p < 0.001). Conclusion Sampling of cervical lymph nodes level-by-level yields more nodes than the en bloc technique. Further studies could verify whether neck dissection sampling technique has any impact on survival rates.
