Is lateral rhinotomy, an adequate surgical approach for juvenile naso-pharyngeal angiofibroma

ABSTRACT

The objective of the study was to determine optimal surgical approach in patients with JNA. Retrospective, descriptive. The study was carried out at the department of Ear, Nose, Throat, Head and Neck Surgery, Dow Medical College and Civil Hospital, Karachi from 1996-2007. All the young males who visited out patients department with the history of recurrent intractable epistaxis, nasal obstruction, proptosis, fullness and asymmetry of face and were diagnosed as a case of JNA on the basis of history, clinical examination and CT scan, were included in the study. All the diagnosed cases of recurrent JNA and other causes with similar symptoms were excluded. Almost all the included patients underwent digital subtraction angiography with embolization of main feeding vessel 24-48 hours before surgery. Chandler staging system was used to stage the disease. Lateral rhinotomy approach was employed in majority of the cases for exploration and removal of JNA. The out come were discussed for lateral rhinotomy as an optimal surgical approach in patients with JNA in term of ease of approach, complete removal and recurrence. Total of 53 cases of JNA were included in the study. All were young males between the age group from 8-22 years. Majority of the patients were between 13 to 18 years of age. No female patient was reported. Majority of the patients presented with triad of symptoms with recurrent epistaxis [n-53] nasal obstruction [n-53] and nasal mass [n-41]. Others presented with additional symptoms of nasal discharge [n-46], snoring [n-43] speech defect [n-32], headache [n-23], facial asymmetry [n-20], visual problems, like proptosis and diplopia [n-09] and impairment of hearing [n-19]. Diagnosis was made by clinical examination, C T scan and angiographic findings with embolization 24-48 hour prior to surgery [n-45]. Lateral rhinotomy approach for extirpation of the JNA was employed in 41 cases and Weber-Furguson approach in 07 patients. Midfacial degloving approach was used in 03 patients and in 02 cases transpalatal approach was employed where the extent of the lesion was limited to nasopharynx. Recurrence was found in 03 cases of JNA approached through lateral rhinotomy during 1-2 years follow-up. Lateral rhinotomy approach to nose and nasopharynx gives an adequate exposure in almost all the cases of JNA
