Airway Stenosis Related to Foreign Body Aspiration: An Under-recognized Long term Complication

INTRODUCTION: Sequelae of chronic foreign body aspiration include occlusive granulation tissue formation, which can cause delayed fixed airway stenosis. The aim of this study is to highlight this complication, which should be diagnosed early and treated proactively. METHODS: We present a case series of areca nut aspiration. an organic foreign body commonly chewed in Southeast Asia, complicated by delayed airway stenosis and examine the peculiar nature of areca nut that predisposes to this complication. RESULTS: Long-term sequelae of areca nut aspiration are granulation tissue formation. potentially complicated by airway stenosis due to the mechanical and chemical irritant nature of areca nut. DISCUSSION: Organic impacted foreign bodies such as areca nut can cause delayed complications of airway stenosis. Both the sharp edges of the areca nut and chemical irritation caused by alkaloids released by the nut in constant contact with the airway mucosa can predispose to this long-term complication. Early diagnosis and appropriate therapeutic interventions such as balloon bronchoplasty can help restore airway patency and prevent lung damage.
