Summary
A rare variation of the superior thyroid artery originating from the common carotid artery was observed during neck surgery. This anatomical finding is crucial for surgeons to identify neck vessels accurately and prevent surgical errors.
Area of Science:
- Anatomy
- Vascular Surgery
- Surgical Oncology
Context:
- Functional neck dissection for tongue cancer metastasis.
- Observation of an anomalous superior thyroid artery origin.
Purpose:
- To document and highlight a rare anatomical variation of the superior thyroid artery.
- To emphasize the importance of recognizing vascular anomalies in neck surgery.
Summary:
- The superior thyroid artery, typically a branch of the external carotid artery, was found to originate from the common carotid artery 3.5 cm below its bifurcation.
- This anatomical variation is significant as no vessels normally arise from the common carotid artery in this region.
Impact:
- Enhances surgical precision during neck dissections.
- Reduces the risk of inadvertent injury to major neck vessels.
- Improves patient safety by informing surgical planning and execution.
