Bleeding in the ear canal

Introduction Ear canal bleeding is also known as ear bleeding, and ear bleeding often occurs when the eardrum is perforated or the skull base is fractured. Internal ear trauma, light convulsions and convulsions, mainly manifested as sensorine deafness, tinnitus, dizziness, nausea, vomiting, nystagmus and balance disorders. Severe cases with bone fractures, manifested as intra-hemorrhage, such as the tympanic membrane is not worn, the tympanic membrane in the tympanic membrane blue, tympanic membrane rupture cerebrospinal fluid otorrhea, out of red blood, or clear liquid. Sometimes the merger is flawed.

Cause

Perforation of the eardrum or skull base fracture. The auricle is exposed to both sides of the skull and is susceptible to trauma. Common auricle injuries include contusions, cuts, bites, lacerations, frostbite and burns. Common causes of tympanic membrane trauma are earing (matchsticks, hairpins, and needles) and sudden changes in external auditory canal pressure (such as cannoning, high diving, slap, etc.). The fracture of the tibia is caused by a car accident, falling, hitting the occipital occipital or war wounds. There are bleeding, deafness, tinnitus, earache, and occasional dizziness. The tympanic membrane is irregularly perforated, and there are bloodstains on the perforated edge. Sometimes, the ossicle is damaged and dislocated.

1. When the otoscope is examined, there is blood in the external auditory canal.

3, after the injury, dizziness or hearing loss, should pay attention to consciousness, breathing, heartbeat, pulse, blood pressure, pupil, other nervous system and craniofacial injuries, general conditions.

Differential diagnosis

Differential diagnosis of ear canal bleeding:

1. Ear bleeding: external force damages the symptoms caused by the tympanic membrane or inflammatory reaction, and bleeds when the external auditory canal is dug.

2, bloody ear secretions: Otorrhea Antrum auris discharge (Etorrhea Antrum auris discharge) is also called ear discharge, external auditory canal discharge, ear leak. External auditory canal discharge refers to a pathological phenomenon of abnormal fluid accumulation or outflow in the external auditory canal, which is one of the common symptoms of the ear. The discharge may be continuous or intermittent, and may be serous, mucoid, purulent, bloody, or mixed. The external auditory canal of the patient was examined by otoscopy, and fluids of various natures were found to flow out. Can adhere to the external auditory canal or accumulate in the ear canal.
