INTRODUCTION
There are a limited number of reports in the literature that document foreign bodies in the paranasal sinus. Additionally, there are limited reports on the natural clinical course and impact of foreign bodies in the maxillary sinus.1 Such clinical situations represent a unique challenge for surgeons. Treatment guidelines about this uncommon phenomenon are not well established because prospective or controlled studies are not feasible due to the limited number of subjects. Guidelines on some factors have been reported by surgeons in regard to the location of the foreign body, proximity to vital neurovascular anatomical structures, duration of foreign body impact, and risk of surgical retrieval.1,2
In this article, we describe an unusual case of a transfacial penetrating injury with a metallic foreign body (blades of scissors) that remained asymptomatic for about 40 years and was successfully removed via an endoscopic approach. Furthermore, we aim to address issues about management of foreign bodies in the sinonasal cavity to provide guidance and aid in decision-making and treatment processes.
