Résumé

The reported risk of a cranial nerve (CN) injury is up to 1 in 4 patients in large registries of carotid body tumor (CBT) resection. Functional outcome for this population is unknown. We evaluated consecutive patients who underwent CBT resection from November 2013 through October 2020. Demographics, intraoperative details, complications, and outcomes were recorded from the medical record. Permanent CN nerve injury was defined as deficits lasting >6 months. Frequency statistics, averages, chi-squared test, and multiple logistic regression were completed for primary end points of complications and disease-free survival. Patient-reported outcomes were gathered via telephone survey of patients conducted in September 2021. Fifty-one patients presented with CBTs and the following Shamblin classes: I (n = 7; 14%), II (n = 36; 69%), and III (n = 9; 17%). Head and neck oncology and vascular surgery jointly did 52% of CBT resections, including 6 of 9 Shamblin III cases. Eight patients (15.3%, all Shamblin II or III) suffered a total of 12 CN injuries - 8 CN XII (5 temporary and 3 permanent), 3 CN X (all permanent), and 1 CN XI (permanent). Seven of the CN injury subgroup had preoperative embolization and 5 were joint oncology/vascular cases. In addition, 4 separate carotid injuries required repair. Notably, all patients had disease-free survival postoperatively at a mean follow-up of 6 months. Patient-reported outcomes obtained in 70.6% of patients 1 year or more from index operation demonstrated that two-thirds of patients live without any permanent functional deficits, and the majority of those with continued deficits rate the symptoms as daily but mild in severity. In a series of complex CBT patients treated with preoperative embolization capabilities and multidisciplinary surgical approach, disease-free survival was achieved in all patients despite a high rate of iatrogenic CN injuries, most commonly CN XII. Patient-reported outcomes survey results indicate that injuries identified on clinical exam underreport patients' true postoperative CN deficits - especially branches of CN X. This data support the practice of aggressive primary resection of CBTs while providing guidance for expected functional outcomes due to CN injury risk.

BACKGROUND BACKGROUND
The reported risk of a cranial nerve (CN) injury is up to 1 in 4 patients in large registries of carotid body tumor (CBT) resection. Functional outcome for this population is unknown.
METHODS METHODS
We evaluated consecutive patients who underwent CBT resection from November 2013 through October 2020. Demographics, intraoperative details, complications, and outcomes were recorded from the medical record. Permanent CN nerve injury was defined as deficits lasting >6 months. Frequency statistics, averages, chi-squared test, and multiple logistic regression were completed for primary end points of complications and disease-free survival. Patient-reported outcomes were gathered via telephone survey of patients conducted in September 2021.
RESULTS RESULTS
Fifty-one patients presented with CBTs and the following Shamblin classes: I (n = 7; 14%), II (n = 36; 69%), and III (n = 9; 17%). Head and neck oncology and vascular surgery jointly did 52% of CBT resections, including 6 of 9 Shamblin III cases. Eight patients (15.3%, all Shamblin II or III) suffered a total of 12 CN injuries - 8 CN XII (5 temporary and 3 permanent), 3 CN X (all permanent), and 1 CN XI (permanent). Seven of the CN injury subgroup had preoperative embolization and 5 were joint oncology/vascular cases. In addition, 4 separate carotid injuries required repair. Notably, all patients had disease-free survival postoperatively at a mean follow-up of 6 months. Patient-reported outcomes obtained in 70.6% of patients 1 year or more from index operation demonstrated that two-thirds of patients live without any permanent functional deficits, and the majority of those with continued deficits rate the symptoms as daily but mild in severity.
CONCLUSIONS CONCLUSIONS
In a series of complex CBT patients treated with preoperative embolization capabilities and multidisciplinary surgical approach, disease-free survival was achieved in all patients despite a high rate of iatrogenic CN injuries, most commonly CN XII. Patient-reported outcomes survey results indicate that injuries identified on clinical exam underreport patients' true postoperative CN deficits - especially branches of CN X. This data support the practice of aggressive primary resection of CBTs while providing guidance for expected functional outcomes due to CN injury risk.
