Endoscopic assistance in the diagnosis and treatmentof odontogenic maxillary sinus disease

Purpose Endoscopic sinus surgery has become an increasingly popular treatment for most surgical cases of chronic sinusitis. However, in some cases, a modification of the classic Caldwell–Luc operation is unavoidable. The purpose of this paper is to present the outcome of 20 cases with pathology of the maxillary sinus which was approached endoscopically on diagnostic or interventional purpose. The primary indication for endoscopy for 11 cases was acute or chronic odontogenic sinusitis. For six cases, endoscopy was performed for removing a foreign body from the sinus cavity and for the remaining three cases, for diagnostic purpose only.
