ABSTRACT
Introduction: Juvenile nasopharyngeal angiofibroma is a benign vasculartumor.It is commonly found in teen age males. Its site of origin is sphenopalatine foramen. Exact pathogenesis of angiofibroma is not known. It has predictable natural history and growth pattern. This tumor most often involves nasopharynx, nasal cavity, paranasal sinuses, pterygopalatine fossa and infratemporal fossa. It can also involve orbit and can spread intracranially. Its very important to diagnose this tumor very early on the basis of clinical examination and imaging. As early tumor confined to nose and sinuses can be removed exclusively with endoscope. It is very helpful to do angiography before surgery to ascertain itsblood supply and then embolization can be done to reduce intraoperative bleeding. Objective: To describe our experience of Juvenile Nasopharyngeal Angiofibroma cases in ENT Unit-I of Lahore General Hospital. Study Design: Descriptive Study with retrospective analysis after approval from Institutional Review Board (IRB) of LGH/PGMI/AMC Lahore. Methods: We studied 20 patients who underwent surgery in our department from October 2019 to October 2020. We analyzed following factors: age, gender, symptoms, staging, mode of surgery and need for intraoperative blood transfusion, hospital stay, complications and recurrences. Results: Range of patient’s age was 12 to 25 years. Eight patients underwent surgery with endoscope. Mean blood loss was about 400 ml and mean operating time was 140 minutes. All the cases were embolized preoperatively. Conclusion: Endoscopic surgery is a safe and effective method in early stage JNA patients. While patients with advance stage tumors should be managed with combined endoscopic and conventional open approaches.
