두개골막피판 및 역측두근피판을 이용한 전두동 골절의 치료

Abstract

Frontal sinus fracture associated with cerebrospinal fluid rhinorrhea often neccessitates definitive treatment to prevent grave complications such as mucocele, mucopyocele, brain abscess, and other life-threatening ascending infection of intracranium. The treatment should comprise ablation of frontal sinus, obliteration of dead space and existing intracranialnasopharyngeal communication, and restoration of bony barrier for protection of intracranial-nasopharyngeal communication is the most crucial aspect of the treatment because serious ascending intracranial infection such as intracranial abscess or meningitis is a frequent outcome. In 7 patients with frontal sinus fracture, the authors used pericranial flap or reverse temporalis muscle flap based on the superficial temporal vessels to obliterate the dead space and existing intracranial-nasopharyngeal communication after the ablation of frontal sinus and cranialization of posterior wall of frontal sinus. The patients were followed for 4-20 months, and both pericranial and reverse temporalis muscle flaps were effective to prevent the complications of frontal sinus fracture.
