Functional neck dissection: cure and functional results

Area of Science:

• Oncology
• Surgical Oncology
• Head and Neck Surgery

Background:

• Neck dissection is a critical surgical procedure for head and neck cancer management.
• Evaluating functional outcomes alongside oncologic cure is essential for patient quality of life.
• Previous studies have focused on oncologic outcomes, with less emphasis on functional deficits post-dissection.

Purpose of the Study:

• To evaluate the oncologic cure and functional results of functional neck dissections.
• To assess the recurrence rates in both elective and curative functional neck dissections.
• To investigate potential neurogenic deficits and their impact on functional outcomes.

Main Methods:

• Retrospective analysis of 133 functional neck dissections performed between 1992-1997.
• Evaluation of overall and stratified recurrence rates (elective vs. curative).
• Electromyography (EMG) to assess trapezius and sternocleidomastoid muscle function in 56 patients.
• Doppler ultrasonography to assess internal jugular vein patency and flow.

Main Results:

• An overall recurrence rate of 3% was observed.
• Elective functional neck dissections had a 1.4% recurrence rate, while curative dissections had a 5% rate.
• Severe neurogenic deficit was noted in 12.5% of the trapezius muscles and 21.4% of sternocleidomastoid muscles.
• Doppler ultrasonography confirmed normal internal jugular vein flow and diameter in all assessed patients.

Conclusions:

• Functional neck dissection is a dependable surgical technique for head and neck cancer.
• The procedure achieves a high cure rate with satisfactory functional results.
• Potential neurogenic deficits require careful consideration and monitoring post-operatively.
