Juvenile nasopharyngeal angiofibroma (JNA) incidence has increased in Southeast Asia, with advanced stages (III/IV) being common. Transpalatine surgery is recommended for JNA treatment, while endoscopic resection is best for early stages.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Oncology
Background:
- Juvenile nasopharyngeal angiofibroma (JNA) is a rare, locally invasive tumor.
- Recent trends in JNA epidemiology and management warrant investigation.
Purpose of the Study:
- To analyze the changing trends in JNA, focusing on the north-eastern region of Southeast Asia.
- To evaluate the incidence, presentation, and treatment outcomes of JNA.
Main Methods:
- Retrospective study of eight JNA patients over six months (Oct 2014-Mar 2015).
- Data collected from the Department of Otolaryngology and Head and Neck Surgery, Assam Medical College, Dibrugarh, India.
- Analysis of treatment approaches including transpalatine, transnasal, lateral rhinotomy, and endoscopic surgery.
Main Results:
- Increased JNA incidence compared to previous studies.
- Mean age of presentation: 18 years.
- Over 75% of patients presented with Stage III or IV disease.
- Recurrence rate: 12.5%.
Conclusions:
- Transpalatine surgery is the preferred treatment for JNA.
- Endoscopic resection is suitable only for early-stage (I/II) JNA.
- Further studies are needed to understand JNA trends in the region.
