Abstract

Aim:
Carotid body tumors (Cbts) are uncommon benign head and neck neoplasms. Surgical resection is the treatment of choice for Cbts. However, the anatomical structures adjacent to the tumor tissue may encounter serious injuries during the surgery. Shamblin grading system is a surgical intra-operative scoring system to determine the risks associated with the surgery. Therefore, we aimed to evaluate the correlation of pre-surgical imaging parameters with shamblin grades and intra-operative complications.
Method:
In This Cross Sectional Study, We Enrolled 36 Patients With Cbts. Preoperative cervical CT angiography was acquired in each participant and following parameters were reported in each case: Tumor volume, tumor distance to the base of the skull (TDBS), tumor contact with the internal carotid artery (ICA), and external carotid artery (ECA) and tumor density. Finally, we assessed the relation of pre-surgical imaging parameters with shamblin grades, and intra-operative complications.
Results:
Only tumor volume was significantly correlated with shamblin grades (P < 0.05). The tumor contact with ECA was marginally correlated with shamblin grades (P=0.103); However, other imaging parameters were not significantly correlating with shambling grades. There was a statically significant correlation between ICA contact and tumor volume with ECA injury. In addition, the tumor density significantly correlated with cranial nerves injury. The results of STATA analysis were indicative for 69.44% accordance between radiologic typing and shamblin grading system.
Conclusion:
We found that tumor volume, tumor ICA contact, and tumor density correlate significantly with the shamblin grading system and intra-operative complications.
