Peri-orbital surgical emphysema following functional endoscopic sinus surgery, during extubation.

We present a case of peri-orbital surgical emphysema following functional endoscopic sinus surgery (FESS), due to extubation with simultaneous manual inhalation with a closed expiratory valve. This complication has not been previously reported in association with general anaesthetic and FESS. Patients undergoing FESS are advised against nose blowing. However, we recommend that the anaesthetist working with a surgeon who performs FESS should also be warned not to use manual inhalation with a closed expiratory valve while extubating, as this can cause peri-orbital surgical emphysema.
