Like all procedures, sinus surgery does carry a slight risk of complications. Typically these side effects are just swelling and sometimes crusting after the procedure. However, more severe side effects are:
Bleeding – This typically happens in the first 24 hours after surgery, and usually pretty minor.
Impaired sense of taste or smell – Typically, once that nasal passages are cleared after operation, patients notice an improved sense of smell and taste. However, sometimes the opposite can occur.
Numbness –The tip of your nose and your upper lip and gums may be numb. Feeling will return in a few weeks to a few months.
Dryness – Occasionally, a patient may feel a sensation of dryness in their nose, although this is quite rare.
