Clinico-Pathological Study of Juvenile Nasopharyngeal Angiofibroma

Abstract

Introduction: Anigo-fibroma is vascular swelling arising in the nasopharynx of prepubertal and adolescent males and exhibiting strong tendency to bleed, also termed as nasopharyngeal fibroma or a nasopharyngeal angiofibroma. It accounts for less than 0.5% of all head & neck tumour. It occurs almost exclusively in adolescent male, though rarely found in children and elderly young. It is a rare <1% of head and neck tumors benign mesenchymal neoplasm composed of a vascular proliferation within a cellular, densely collagenizedstroma, typically originating in the nasopharynx, affecting adolescent males. It occurs most often in male adolescents with an average age at diagnosis of 14-16 years. Anyway, there are very few studies, regarding Juvenile Nasopharyngeal Angiofibroma in Bangladrsh and there is not much national data about this issue. Hence, the researcher purposively a total of 30 patients of juvenile nasophryngeal angiofibroma (JNA) included in this study from ENT department of Shaheed Ziaur Rahman Medical College, Bogura, Bangladesh. The aim of this study was to find out the common mode of clinical presentation with their site of extension and different surgical approaches adopted for them. Methods & Materials: This prospective observational study was conducted in the Department of otolaryngology and head, neck surgery of Shaheed Ziaur Rahman Medical College, Bogura, Bangladesh, which is the 2nd generation tertiary level medical service institution during the period from Jan 2017 to Dec 2019. All data were analyzed by using simple statistical data analyzed tools. Result: Almost all the present with recurrent epistaxis 28 (93.33%), following by nasal obstruction 26 (86.66%), nasal discharge 25 (83.33%), facial swelling 10 (33.33%), protrusion of the eyeball 4 (13.33%), aural symptoms 3 (10%) and head-ache 2 (6.66%). Majority of our patient presented with multiple symptoms. Analysis of the finding showed that 100% had nasopharyngeal mass, nasal mass 86.66% palatal bulging 66.66%, swelling of the cheek 33.33%, proptosis 13.33% and headache with blurring of vision 6.66%, these are obtained after thorough clinical examination both local and general. Extension of the tumour assessed on the basis C scan, MRI, as well as observation on the operation showed, nasal cavity 100% and into the pterygopalantine fossa 40%, infratemporal fossa 33.33%, orbit 13.33%, oropharynx 10% maxillary antrum 6.66%, sphenoid sinus 3.33%, ethmoidal sinus 3.33% and 6.66% infra oranial extension. Regarding treatment surgical resection was the most common principal mode of treatment offered to the 93.33% patient but radiotherapy given in 6.66% patient. Conclusion: All young males of this study with nasal obstruction or nose bleed (or both) should be suspected of having juvenile angiofibroma. Angiography to find out feeding vessel to do pre-operative embolization is helpful for surgery. This together with hypotensive anaesthesia and operated by a skilled surgeon having sound knowledge about nasopharynx can lessen the haemorrhage, thereby reduce the mortality and morbidity.
