Abstract
Background: Virtual Endoscopy of nasal cavity and paranasal sinuses is an adjuvant diagnostic modality in otorhinology. Virtual endoscopy could simulate conventional endoscope in demonstrating anatomic structures of nasal cavity and could help in diagnosis in obstructive nasal diseases in cases difficult to use the rigid nasal endoscope but still can’t replace conventional nasal endoscope.
Aim: The aim of this study was to compare the virtual with the conventional nasal endoscopy in display anatomical structures and pathological lesions in nasal cavity and paranasal sinuses with emphasis of its advantages & disadvantages, limitations and future direction.
Patients and Methods: This is a prospective comparative study carried out during the period March from 2012 to July 2016. It included 106 patients who complained of chronic nasal symptoms as nasal obstruction & nasal discharge. MSCT done to all patients, then reformatted images transferred to workstation software to obtain virtual images of nasal cavity and paranasal sinuses compared with the conventional nasal endoscopic images of the same patients.
Results: Virtual nasal endoscopy has the ability to demonstrate clearly anatomic structures in the nasal cavity like: inferior turbinate, nasal septum, middle turbinate and paranasal sinuses, also has the ability to diagnose some obstructive nasal diseases as deviated nasal septum, hypertrophied inferior turbinate, congenital choanal atresia and sinonasal polyposis. The main limitation of virtual nasal endoscopy was the inability to differentiate colouration and take biopsy.
Conclusion: Virtual nasal endoscopy is a fast and noninvasive technique. virtual nasal endoscopy can display normal structures and pathological lesions in the nasal cavity. Its ability to visualize is comparable with conventional nasal endoscope except for evaluating mucosal surface and secretions. In the future, this technique will possibly be a basic tool of computer-assisted surgical procedure in the otorhinology.
