Histologic examination of a preoperative biopsy sample revealed multiple ulcerated ceruminous gland adenomas in the affected ear of cat 1. Histologic examination of the submitted tissue from cat 2 confirmed ceruminous cystomatosis with surface colonization of yeast compatible with <jats:italic>Malassezia<\/jats:italic> spp.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s003\">\n<jats:title>TREATMENT AND OUTCOME<\/jats:title>\n<jats:p>Both cats underwent partial resection of the upper third of the affected vertical ear canal and associated diseased skin. The incised margin of the pinna was sutured to the margin of the remaining portion of the vertical ear canal with absorbable sutures. Both cats were disease free over a 12-month (cat 1) or 10-month (cat 2) follow-up period. Cat 1 later developed a small ceruminous gland adenocarcinoma in the adjacent rostrolateral margin of the vertical ear canal 1 year after surgery; the mass was resected, and the patient was free of recurrence 4 months later.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"s004\">\n<jats:title>CLINICAL RELEVANCE<\/jats:title>\n<jats:p>Partial resection was an effective alternative to complete vertical ear canal resection for lesions involving the upper third of the vertical ear canal in these cats; the partial resection procedure was deemed simpler to perform and less traumatic to the cat. Functional and cosmetic results were excellent, with preservation of the overall anatomy of the external auditory canal.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/javma.255.12.1365","type":"journal-article","created":{"date-parts":[[2019,12,3]],"date-time":"2019-12-03T16:26:03Z","timestamp":1575390363000},"page":"1365-1368","source":"Crossref","is-referenced-by-count":8,"title":["Partial vertical ear canal resection in two cats"],"prefix":"10.2460","volume":"255","author":[{"given":"Michael M.","family":"Pavletic","sequence":"first","affiliation":[{"name":"1Department of Surgery, Angell Animal Medical Center, 350 S Huntington Ave, Boston, MA 02130."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"J Am Anim Hosp Assoc","doi-asserted-by":"publisher","first-page":"371","DOI":"10.5326\/0420371","article-title":"Subtotal ear canal ablation in 18 dogs and one cat with minimal distal ear canal pathology","volume":"42","author":"Mathews","year":"2006"},{"key":"ref2","series-title":"Vet Clin North Am Small Anim Pract","doi-asserted-by":"publisher","first-page":"567","DOI":"10.1016\/j.cvsm.2003.10.011","article-title":"Surgery of the ear and pinna","volume":"34","author":"Lanz","year":"2004"},{"key":"ref3","series-title":"Probl Vet Med","first-page":"239","article-title":"Surgery of the ear canal","volume":"3","author":"Elkins","year":"1991"},{"key":"ref4","series-title":"Vet Clin North Am Small Anim Pract","doi-asserted-by":"publisher","first-page":"813","DOI":"10.1016\/S0195-5616(88)50083-9","article-title":"Surgical management of otitis externa","volume":"18","author":"Bradley","year":"1988"},{"key":"ref5","series-title":"Vet Clin North Am Small Anim Pract","doi-asserted-by":"publisher","first-page":"821","DOI":"10.1016\/S0195-5616(88)50084-0","article-title":"Surgical management of advanced ear disease","volume":"18","author":"Hobson","year":"1988"},{"key":"ref6","series-title":"Vet Med Small Anim Clin","first-page":"1007","article-title":"Ablation of the ear canal for treatment of chronic suppurative otitis externa in a cat","volume":"75","author":"Hitt","year":"1980"},{"key":"ref7","series-title":"J Small Anim Pract","doi-asserted-by":"publisher","first-page":"430","DOI":"10.1111\/j.1748-5827.2003.tb00101.x","article-title":"Total ear canal ablation in the cat: indications, morbidity and long-term survival","volume":"44","author":"Bacon","year":"2003"},{"key":"ref8","series-title":"Vet Surg","doi-asserted-by":"publisher","first-page":"435","DOI":"10.1111\/j.1532-950x.2004.04065.x","article-title":"Cosmetic results of a ventrally based advancement flap for closure of total ear canal ablations in 6 cats: 2002\u20132003","volume":"33","author":"McNabb","year":"2004"},{"key":"ref9","series-title":"Vet Clin North Am Small Anim Pract","doi-asserted-by":"publisher","first-page":"859","DOI":"10.1016\/S0195-5616(88)50086-4","article-title":"Tumors of the ear canal","volume":"18","author":"Rogers","year":"1988"}],"container-title":["Journal of the American Veterinary Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/avmajournals.avma.org\/view\/journals\/javma\/255\/12\/javma.255.12.1365.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/avmajournals.avma.org\/downloadpdf\/journals\/javma\/255\/12\/javma.255.12.1365.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/avmajournals.avma.org\/downloadpdf\/journals\/javma\/255\/12\/javma.255.12.1365.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T00:38:18Z","timestamp":1696552698000},"score":1,"resource":{"primary":{"URL":"https:\/\/avmajournals.avma.org\/view\/journals\/javma\/255\/12\/javma.255.12.1365.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12,15]]},"references-count":9,"journal-issue":{"issue":"12"},"URL":"https:\/\/doi.org\/10.2460\/javma.255.12.1365","relation":{},"ISSN":["0003-1488"],"issn-type":[{"value":"0003-1488","type":"print"}],"subject":[],"published":{"date-parts":[[2019,12,15]]}}}
