Complications may also occur with treatment; for example a granuloma can form at the suture site.[2] Also, the sutured wound can tear again, as occurs when there is excessive pressure in the airways from ventilation.[2] However, for people who do receive surgery soon after the injury to repair the lesion, outcome is usually good; the long-term outcome is good for over 90% of people who have TBI surgically repaired early in treatment.[14] Even when surgery is performed years after the injury, the outlook is good, with low rates of death and disability and good chances of preserving lung function.[29]
