Surgery is only half of the success of the treatment, the other half depends on regular post-operative review and necessary treatment and medication support. Immediately after the surgery, the epithelial regeneration recovery phase begins. During this period, granules, vesicles, scabs, and adhesions may form in the nasal cavity, and if left untreated, blocking the sinus openings, sinusitis may quickly recur. In addition, adherence to nasal medication and medication is also an effective means to avoid postoperative complications and recurrence. Clinical experience shows that the quality of postoperative management is directly related to the outcome of nasal endoscopic surgery. Failure to perform regular review after surgery or through inappropriate treatment can often lead to new lesions and recurrence in the nasal cavity, which are more difficult to manage. Therefore, patients must follow the doctor’s instructions for regular review and regular medication after surgery to consolidate the surgical effect and cure the disease completely.
