Ear, discharge from

An emission of fluid from the ear, also called otorrhoea. It may be due to outer-ear infection (see otitis externa). It may also follow perforation of the eardrum (see eardrum, perforated), usually due to middle-ear infection (see otitis media). Rarely, after a skull fracture, cerebrospinal fluid or blood may be discharged. A swab may be taken of the discharge and analysed to identify any infection. Hearing tests may be performed. X-rays of the skull are taken if there has been a head injury or serious middle-ear infection is suspected. Treatment usually includes antibiotic drugs.
