Post-traumatic fronto-ethmoid osteomyelitis treated with free muscle transfer.

Intractable frontal sinus infection after obliteration of the injured sinus and nasofrontal duct has become a less common injury nowadays.

Nonetheless if recurrent infection involves both the frontal and ethmoid sinuses, local tissues may not suffice for obliteration of the dead space.
