Retrospective Study |
From the Department of Companion Animal Clinical Studies, Faculty of Veterinary Science (Kirberger, Steenkamp, Spotswood, Miller), and the School of Dentistry, Faculty of Health Sciences (Boy), University of Pretoria, Private Bag X04, Onderstepoort, Gauteng, 0110, South Africa; and the Cape Animal Medical Center (van Zyl), 78 Rossmead Avenue, Cape Town, 8000, South Africa.
Medical records of seven dachshunds with congenital nasopharyngeal stenosis from abnormally thickened palatopharyngeal muscles were reviewed. The intrapharyngeal ostium in all cases consisted of only a narrow slit. Dogs were presented with various clinical signsthe most common being dyspnea, expiratory cheek puff, salivation, pharyngeal dysphagia, oral dysphagia (to a lesser extent), and macroglossia. Diagnostic procedures included direct pharyngeal inspection, pharyngeal and thoracic radiography, fluoroscopy, lingual ultrasonography, biopsies in two dogs, and a postmortem examination in one dog. Diagnoses were readily made with radiographs and visual examinations. Macroglossia was confirmed with transcutaneous ultrasonography or a transmandibular finger test.
