Prospective study of concordance between anterior rhinoscopy and nasal endoscopy in diagnosing nasal polyposis
AbstractDiagnostic capabilities of nasal endoscopy and routine rhinoscopy is compared with respect to nasal poliposis. Anterior rhinoscopy and nasal endoscopy were performed after initial clinical and X-ray diagnosis of rhinosinusitis and nasal obstruction in 47 cases above 10 year age. Rhinoscopy could detect polyp in 13 (27.7%) cases. Nasal endoscopy detected 19 (40.4%) cases of polyp. One rhinoscopic diagnosis of polyp was negated consequent to nasal endoscopy as mere mucoid collection. Nasal endoscopy is very effective and superior application than rhinoscopy both in gaining access and proximate visualization of nasal and sinus pathologies. It also scores over CT scan by permitting gross examination of lesions and their possible nature. The technique is easy and be routinely adopted specially in cases where sinus symptoms are not well explained.
