Fractures of the brow bone do not usually result in bleeding from the nostrils, but if accompanied by a skull base fracture may result in bleeding from the ears or nose.
Fractures of the brow bone are linear and do not usually result in bleeding from the nostrils, but if accompanied by a skull base fracture may result in bleeding from the ears or nose or cerebrospinal fluid leakage.
Fractures of the anterior cranial fossa most often involve the orbital roof and sieve bones, and bleeding from the fracture may flow out through the anterior nostril or into the orbit to form a bruise under the eyelid and bulbar conjunctiva.
Fractures of the middle cranial fossa may involve the pterygoid and temporal bones, and blood and cerebrospinal fluid may flow through the pterygoid sinus opening to the nasopharynx for outflow or along the Eustachian tube to the nasopharynx for outflow if the tympanic membrane is not broken.
Fractures of the brow bone with or without bleeding from the nostrils are recommended for prompt medical attention to determine whether there is a combined intracranial injury, and according to and for targeted treatment.
