Patient has tendency of keloid formation
CT scan plain para nasal sinuses was taken. It showed blow out fracture of inferior wall of right orbit with prolapse of orbital contents. The prolapsed orbital contents resembles a tear drop hence the name "tear drop sign".
Since this patient has keloid forming tendency, facial incision was avoided.
