Complications that can occur after surgery include haematoma, (blood clotting) this is rare and uncommon, yet possible. The nerves near the ears can be traumatised and you may feel numbness for some time, but this is usually temporary until the nerves mend and you will gradually obtain normal sensation, this may take up to 12 months.
Other risk factors are infection and reactions to the anaesthesia. Your surgeon will give you antibiotics prior to surgery to eliminate infection. If you have any problems with anaesthetic you must inform the anaesthetist prior to surgery. Smokers may experience a delay the healing process, but ultimately still obtain the same results.
