Empty nose syndrome is possible after surgery for sinusitis, depending mainly on the severity of the lesion. In the case of simple sinusitis, it is usually not present. In the case of combined nasal polyps, and more severe nasal polyps, there is a large polyp-like change in the mucosa of the nasal cavity, and the surgical excision must be extensive, and the postoperative empty nose syndrome can occur. It is mainly a dry and burning sensation in the nasal cavity with a large amount of dry crust. There is no way to avoid this condition, because if the excision is not complete, it can very easily lead to a recurrence in the short term, and it is very difficult to operate for recurrence. After surgery, medication is needed to effectively control the symptoms, such as using saline rinses to keep the nasal cavity moist and applying glucocorticoid-based nasal sprays to promote the recovery of mucosal function.
