The ear is washed and a small incision made in the eardrum. Any fluid that is present is then aspirated, the tube of choice inserted, and the ear packed with cotton to control any slight bleeding that might occur. This is known as conventional (or cold knife) myringotomy and usually heals in one to two days. [13]
Normal ear drum. A perforated eardrum (tympanic membrane perforation) is a prick in the eardrum. It can be caused by infection (otitis media), trauma, overpressure (loud noise), inappropriate ear clearing, and changes in middle ear pressure. An otoscope can be used to view the eardrum to diagnose a perforation. Perforations may heal naturally ...
Some dogs do respond to ear cropping since, after the surgery, the ears are erect, the ear canals are open, and they have increased airflow. Surgery is usually a treatment option of last resort ...
The ear thereby converts and amplifies vibration in the air to vibration in cochlear fluid. [1] The malleus bone bridges the gap between the eardrum and the other ossicles. [2] Rupture or perforation of the eardrum can lead to conductive hearing loss. Collapse or retraction of the eardrum can cause conductive hearing loss or cholesteatoma.
The disease varies from mild to severe, depending on the amount of von Willebrand factor present in the dog. Signs include spontaneous bleeding and excessive bleeding following surgery, injury, or during an estrous cycle. [42] Thrombocytopenia* is a common condition in dogs characterized by low platelet counts.
Otorrhea (ear discharge) is the most common complication of tympanostomy tube placement, affecting between 25–75% of children receiving this procedure. [2] [6] [9] [10] Saline washouts and antibiotic drops at the time of surgery are effective measures to reduce rates of otorrhea, which is why antibiotic ear drops are not routinely prescribed.
The surgery takes 1 ⁄ 2 to 1 hour if done through the ear canal and 1 + 1 ⁄ 2 to 2 hours if an incision is needed. It is done under local or general anesthesia . It is done on an inpatient or day case basis and is successful 85–90% of the time.
Dogs with hemangiosarcoma rarely show clinical signs until the tumor has become very large and has metastasized. Typically, clinical signs are due to hypovolemia after the tumor ruptures, causing extensive bleeding. Owners of the affected dogs often discover that the dog has hemangiosarcoma only after the dog collapses.
