Clinical outcomes of coblation-assisted pediatric endoscopic endonasal skull base surgery.

BACKGROUND

Pediatric skull base surgeries are confined by developmental and anatomical issues. Radiofrequency coblation integrates the functions of ablation, suction, and coagulation with the ability to dissolve tissues with limited thermal injury, making it an ideal instrument for pediatric skull base surgery. We sought to evaluated the clinical outcomes of coblation-assisted pediatric endoscopic skull base surgery.

METHODS

Medical records of patients under 15 years of age undergoing endoscopic skull base surgery were retrospectively reviewed. The estimated blood loss (EBL)/operating time (OT) and Wormald grade were used for intraoperative blood loss grading.

RESULTS

Generally, 28 patients (17 males, 11 females) with an average age of 8.4 ± 4.2 years, (range, 11 months to 15 years old) were included. Coblation was applied in 20 patients for mucosa coagulation and handling, cartilage removal, tumor separation and excision. The primary diagnoses included juvenile nasopharyngeal angiofibroma (n = 5), traumatic cerebrospinal fluid (CSF) leak (n = 6), congenital meningoencephalocele (n = 6) and miscellaneous sinonasal and skull base neoplasm (n = 11). The application of coblation was related with a significant decrease in EBL/OT (34.1 ± 17.5 vs 56.3 ± 22.6 ml/h, p = 0.048) and Wormald grade (5.7 ± 1.5 vs 6.9 ± 2.0, p = 0.038), compared with the traditional techniques. All surgical procedures were uneventful. No significant difference in postoperative complications, including cranial nerve dysfunction and CSF rhinorrhea were documented during the follow-up period (average, 34.7 ± 4.4 months).

CONCLUSION

We suggested the coblation be a safe and effective instrument for pediatric skull base surgery.
