Before performing ear surgery, the primary examination is required — blood tests (general, for HIV, RW, hepatitis B, and C), bleeding time test, chest X-ray, and ECG (electrocardiogram).
2 weeks before the plastic ear surgery, the doctor advises refusing medication intake that can affect blood coagulation.
Smokers are advised to quit smoking at least 4 weeks before having plastic surgery (or at least significantly reduce the number of cigarettes smoked).
It would be best if you also stopped drinking alcohol at this time (this complicates the postoperative period).
The day before the operation, you need to have a fast day, and on the day of otoplasty — refuse food entirely.
