Objective:
Juvenile nasopharyngeal angiofibroma may be successfully resected using endoscopic techniques. However, the use of coblation technology for such resection has not been described. This study aimed to document cases of Fisch class I juvenile nasopharyngeal angiofibroma with limited nasopharyngeal and nasal cavity extension, which were completely resected using an endoscopic coblation technique.
Methods:
We retrospectively studied 23 patients with juvenile nasopharyngeal angiofibroma who underwent resection with either traditional endoscopic instruments (n = 12) or coblation (n = 11). Intra-operative blood loss and overall operative time were recorded.
Results:
The mean tumour resection time for coblation and traditional endoscopic instruments was 87 and 136 minutes, respectively (t = 9.962, p < 0.001). Mean intra-operative blood loss was 121 and 420 ml, respectively (t = 28.944, p < 0.001), a significant difference. Both techniques achieved complete tumour resection with minimal damage to adjacent tissues, and no recurrence in any patient.
Conclusion:
Coblation successfully achieves transnasal endoscopic resection of juvenile nasopharyngeal angiofibroma (Fisch class I), with good surgical margins and minimal blood loss.
