Endoscopic intranasal ethmoidectomy and transantral Et hmoidectomy guided with sinoscopy in treatment of patients with recurrent nasal polyposis: Comparative study

Thirteen patients with recurrent nasal polypi were treated in ENT department, Assiut University hospital with two types of ethmoidectomies. Twelve intranasal endoscopic ethmoidectomies and thirteen transantral ethmoidectomies guided with sinoscopy were done to to those patients. results and complications of both modalities were compared. No major complication was recorded for both mothods. Complete recurrence was near to each other [8% Vs 7%]. Partial recurrence for internasal endoscopic ethmoidectomy is double that for transantral ethmoidectomy guided with sinoscopy [34% Vs 17%]
