Summary
Temporary external carotid artery (ECA) restriction using a Rummel tourniquet may reduce blood loss during extensive maxillofacial tumor resections. This technique was feasible and safe in a small case series, warranting further investigation.
Area of Science:
- Surgical Oncology
- Vascular Surgery
- Head and Neck Surgery
Background:
- Major maxillofacial tumor resections often involve significant intraoperative blood loss.
- The external carotid artery (ECA) and its branches supply rich vascularity to these tumors.
Purpose of the Study:
- To evaluate the feasibility and safety of temporary proximal ECA restriction in patients undergoing extensive maxillofacial tumor resection.
- To assess the impact of ECA restriction on intraoperative blood loss.
Main Methods:
- A case series of three patients undergoing extensive maxillofacial tumor resection.
- Temporary proximal ECA restriction was applied using a Rummel tourniquet via cervical exposure.
Main Results:
- Estimated blood loss ranged from 550 to 1500 mL.
- No postoperative neurological deficits or delayed arterial hemorrhage were observed.
- The technique allowed for reversible arterial inflow modulation.
Conclusions:
- Temporary proximal ECA restriction may be a practical adjunct for managing blood loss in selected maxillofacial tumor resections.
- Further studies are needed to confirm its clinical value due to the small sample size and lack of comparative analysis.
