title: Middle ear polyps: results of traction avulsion after a lateral approach to the ear canal in 62 cats (2004-2014).
abstract: Objectives The objective of this study was to report the surgical outcome and complication rate of deep traction avulsion (TA) of feline aural inflammatory polyps after a lateral approach (LA) to the ear canal. Methods This was a retrospective analysis of data retrieved from an electronic database of 62 cats treated with TA after an LA (TALA) for removal of ear canal polyps. Long-term outcome was assessed via a telephone questionnaire survey with the owners. Results Domestic shorthair cats (48%) and Maine Coons (37%) were over-represented. The most common presenting clinical signs were otorrhoea, ear scratching and head shaking. Video-otoscopic examination confirmed a polypous mass in the ear canal in all patients. All 62 cats underwent TALA, with a mean surgical time of 33 mins for experienced surgeons (n = 4) and 48 mins (n = 12) for less experienced surgeons. The recurrence rate of polyp regrowth for experienced surgeons was 14.3% vs 35% for the less experienced surgeons. Postoperative complications included Horner's syndrome (11.5%) and facial nerve paralysis (3%). Otitis interna was not observed. Conclusions and relevance A lateral approach to the ear canal in combination with deep TA of an aural inflammatory polyp is an effective first-line technique that results in a low recurrence and complication rate.
