The main consequence of injury to the postganglionic sympathetic fibers traversing the middle ear is Horner’s syndrome. This condition is reported in 6% of cats prior to surgery and in 27–42% of cats following total ear canal ablation (TECA) with bulla osteotomy; it may be permanent in 14–27% of cases. Among dogs and cats undergoing ear canal ablation, approximately 8% may present with facial nerve paralysis.
Hemorrhage is an uncommon complication, with an incidence of about 3%. When it occurs, it is typically due to injury of the retroglenoid vein, which retracts into the retroglenoid foramen, making ligation impossible. In such cases, hemostasis is achieved by applying bone wax to the foramen.
Suture dehiscence is relatively common in dogs following lateral wall resection or when poor surgical technique is employed. Excessive use of electrocautery delays wound healing. When transecting the cartilage, the inner lining of the vertical ear canal may retract, leaving the cartilaginous edge exposed. Consequently, the adjacent skin is often inadvertently sutured to the cartilage rather than to the epithelial lining. This error is a frequent cause of excessive peristomal granulation tissue formation and stenosis.
In the advanced stages of chronic otitis externa, auditory capacity is already diminished, particularly in bilateral disease. Dogs with chronic otitis media have a higher likelihood of experiencing hearing loss compared with those affected solely by otitis externa.
