Evaluation of Four Incisions Used For Radical Neck Dissection- A Comparative Study.

Objective

To evaluate the four commonly used incisions for Radical Neck Dissection on the basis of certain defined parameters. Patients and

Methods

The investigators designed and implemented a prospective comparative study composed of patients with oral squamous cell carcinoma. The predictor variable was time taken to raise and close the flaps, accessibility to the neck lymph nodes, injury to vital structures and scar cosmesis followed up to a period of three months. Descriptive statistics were computed.

Results

The sample was composed of 40 patients grouped as follows: Macfee Incision (=10 patients), Modified Macfee Incision (=10 patients), Modified Schobinger Incision (=10 patients) and Reverse Hockey Stick Incision (=10 patients). Group A, consisiting of the patients with Macfee Incision, took the least time to close among all the groups ( Mean= 32.60 minutes) while Group C (patients with Modified Schobinger Incision) required the most time for closure ( Mean= 51.90 minutes). The Modified Schobinger Incision provided best exposure to neck node levels. The Macfee Incision was found to have the best scar cosmesis among the four incisions.

Conclusion

The results of this study suggest that Modified Schobinger Incision is the preferred incision for adequate access to neck lymphatics while Macfee Incision was found to provide the best scar cosmesis.
