Experiencing difficulty breathing and a dry nose three weeks after functional endoscopic sinus surgery (FESS) is not uncommon. However, it's essential to determine the cause of these symptoms to rule out conditions like empty nose syndrome (ENS). Empty nose syndrome is a rare condition characterized by persistent nasal obstruction and a sensation of empty or wide nasal passages, often following aggressive turbinate reduction surgery. While turbinate reduction wasn't performed in your case, other factors such as changes in nasal anatomy, mucosal healing, or residual swelling could contribute to your symptoms. It's crucial to discuss your concerns with your surgeon to assess the underlying cause of your breathing difficulties and dry nose. They can evaluate your nasal passages, review your surgical history, and determine the appropriate course of action. This may include additional treatments to address any residual inflammation or congestion, such as nasal saline irrigations, humidification, or medications to promote healing. Ensuring open communication with your healthcare provider allows for timely intervention and management of your symptoms to optimize your recovery and improve your nasal function.
