Laryngeal mask anaesthesia is a technique that is very suitable for ophthalmic surgeries, including orbital floor augmentation surgery, due to its convenience and the fact that airway control is much easier than endotracheal tube.

The orbital floor is a thin layer of bone that separates the eye socket from the maxillary sinus and supports the eyeball and surrounding tissues. This is the most common site of injury in the orbital walls due to the very thin bone structure.
