Vascular Control in Nose and Paranasal Sinus Tumours

Area of Science:

• Otolaryngology
• Surgical Oncology
• Vascular Interventional Radiology

Background:

• Effective management of nose and paranasal sinus tumors necessitates precise vascular control.
• Minimizing intraoperative blood loss is key to successful tumor excision and complication reduction.

Purpose of the Study:

• To highlight the significance of pre-operative vascular control in reducing intraoperative bleeding.
• To demonstrate the benefits of achieving bloodless fields for endoscopic tumor excision.
• To evaluate the impact of vascular control on complete tumor removal in Nose and Paranasal Sinus (PNS) tumors.

Main Methods:

• A prospective study involving 23 patients with various Nose and PNS tumors.
• Surgical approaches included Endoscopic or Open methods.
• Intraoperative control of feeding vessels was guided by radiological findings.

Main Results:

• Mean blood loss was 280 ml.
• Mean operating time for the endoscopic approach was under 2 hours.
• All patients achieved complete tumor removal with no significant intraoperative hemorrhage or need for multiple transfusions.

Conclusions:

• Pre-operative identification and control of tumor-feeding vessels lead to superior surgical outcomes.
• Embolization or intraoperative clamping are effective for single-vessel tumors.
• Temporary clamping of main vessels offers a definitive alternative for complex cases.
