Trauma of nose and nasalcavity inflammatory diseases
Trauma of nose and nasal cavity inflammatory diseases
Trauma of nose1.Fracture of nasal boneBecause of its prominent position andprotruding, delicate skeleton, the nose ispredisposed to soft-tissue injury and fracture.50% trauma of nose is external nose traumacaused by impact, fall, bullet and blast. Most ofthem is lacerating wound and nasal bonefracture. Tape of fracture is relatived todirection and size of violence

ClinicalFeaturesMost common symptom is nose bleed andnose pain. Serious patient can lead to shock1.Simple contusions show external nose swellingand ecchymoma. Appears within few hours and mayobscure details of examination.2.Periorbital ecchymosis3.Tenderness4.Fracture of nasal bone can cause displacementand deformity, show bridge of the nose collapse anddeviation and saddle nose

ClinicalFeatures5.Nasal septum fracture can cause nasal obstructionmucosa dilaceration, cartilage or bone reveal. If havehematoma of nasal septum, we can see bulging in oneor two side of nasal septum.6.If nasal root collapses obviously, X-ray or CT should betaken so fracture of sinuses and skull base can be foundearlier. Nasal discharge flood just like water, we shouldthink about cerebrospinal fluid rhinorrhea. Final diagnosiscan be get by chemical examination.7.Open fractures often are comminuted fractures. Besideshave soft tissues injury ,always have foreign bodies
