The "INT-EX Technique": Internal to External Approach in Carotid Body Tumour Surgery.

Carotid body tumours are rare and mostly benign neoplasm. They are slow growing but can evade or exert pressure on neighbouring important neurovascular structures. Hence, surgical resection remains the treatment modality of choice for large tumours partially or completely encasing the carotid arteries. But the surgical resection of these tumours with minimum morbidity is challenging because of their highly vascular nature. Earlier literature has dealt with various aspects of management of carotid body tumours including classification, morbidity, work-up, embolisation and extent of resection. However, the options in techniques of dissection for carotid body tumours have not been elaborated much. Here, we describe a stepwise dissection technique of carotid body tumours from the internal carotid towards the external carotid artery. This surgical technique, named as "the internal to external (INT-EX) technique", provides better control of bleeding during the surgery, ease of dissection and lesser post-operative morbidity.
