【 摘 要 】

The efficacy of conchal cartilage as an alternativo to correct lesions in the esophageal wall was tested. Twenty one mongrel adult dogs, whose weight rangedfrom 11 to 14kg, were randomiy divided in three groups (A, B e C). These animais were submitted to an esophageal segment excision of l x 2cm. The defect was corrected with conchal cartilage alograft. The postoperative attendance and evaluation was done with clinical observation, laboratorial and radiologic examinations during a period of twenty ( group A), forty five (group B) and sixty days (group C). At the end of these periods the animais were euthanized, necropsied and the esophageal segment was evaluated by gross an microscopic examination. It was observed an epitelial growth at the place were the conchal cartilage was sutured. This homograft can be used with sucess in the partial reconstruction of cervical esophageal wall in dogs.
