The majority of cases of orbital emphysema are self-resolving and do not need treatment. The underlying causes and injuries that caused orbital emphysema, on the other hand, may be serious, necessitating urgent intervention including surgery. If related visual symptoms or other acute orbital compression symptoms are present, lateral canthotomy or cantholysis, orbital decompression by needle aspiration, and bone decompression may be required to relieve orbital pressure and preserve vision. Prophylactic oral antibiotics may be needed to prevent secondary infection. == Reference list ==
