ABSTRACT
Background: Temporohyoid osteoarthropathy (THO) is a progressive disease that causes acute onset of peripheral vestibular signs with or without facial paralysis. Ankylosis of temporhyoid joint occurs which predispose to fractures of theinvolved bones and consequently causes the commonly neurological signs observed. Clinical signs vary depending on thestage of the disease and the nerves affected. Surgical treatment is advised to improve survival rates in which the ceratohyoidectomy is currently known as the most advantageous. The aim of the present study is to report a case and outcome ofa ceratohyoidectomy procedure in a Criollo mare presenting THO of the right temporohyoid joint.Case: A 17-year-old Criollo mare was referred to the Equine Clinical Hospital of the Federal University of Pelotas witha 5-day history of facial paralysis on the right side, head tilt and difficulty to chew and swallow. Auricular, palpebraland labial ptosis along with deviation of the lip and nostril to the left were observed. A corneal ulcer was also identifiedin the right eye. Complementary imaging exams (endoscopy of the guttural pouches and radiography of the head) wereperformed and showed thickening of the right stylohyoid bone confirming a diagnosis of THO. Anti-inflammatory andantibiotic therapy were administered and the corneal ulcer was treated with topical antibiotics and autologous serum. Dueto rapid deterioration of clinical signs, the mare was referred to surgery. A ceratohyoidectomty procedure was performedunder general anesthesia. In this procedure, the ceratohyoid bone was disarticulated from the ceratohyoid-basihyoid jointand removed. During the procedure, a branch of the linguofacial vein was accidentally incised causing hemorrhage, thebranch was identified and successfully ligated. Recovery was uneventful. Supportive treatment with anti-inflammatory andantibiotics was continued after surgery and ...(AU)

Esta revisión tiene como meta describir Ia evaluación de Ia placenta equina inmediatamente despuésdei nacimiento, con los hallazgos de Ia macroscópica yla histología, que muestra Ia importancia de Ia evaluación de Ia placenta para el pronóstico neonatal. La placenta es Ia principal conexión entre Ia yegua y el feto durante el embarazo, y los cambios en que puede lIevar a un deterioro dei feto, 10 que resulta en abortos, mortinatos onacimiento de Ias crías no viables y prematuros. Muchas yeguas no pueden mostrar signos clínicos de cambiode Ia placenta durante el embarazo. Por 10 tanto, Ia evaluación de Ia placenta después dei parto y el reconocimiento de características de Ia macroscópica y Ia histología son importantes para el diagnóstico ypronóstico en los recién nacidos de riesgo.
The present review aimed to described the equine placenta evaluation at the parturition characterizedthe grossly and histologic findings, by this way demonstrated the importance to placental evaluation in theneonatal prognosis. The placenta matches a main relation between mare and fetus in gestation, and changes inthis structure can lead to fetal compromise, resulting in abortion, stillbirths, birth of premature and nõn-viablefoals. Some mares did not demonstrate clinical signs of placental compromise during gestation. Therefore, theplacental evaluation in the parturition and the acknowledgment of grossly and histologic features are importantto risk neonates diagnosis and prognosis.
A presente revisão tem como objetivo descrever a avaliação da placenta equina no pós-parto imediato,caracterizando achados macroscópicos e histológicos, apresentando a importância da avaliação placentária para prognóstico neonatal. A placenta representa a principal conexão entre a égua e o feto durante a gestação,sendo que alterações na mesma podem levar ao comprometimento do feto, resultando em abortos, natimorto sou nascimento de potros prematuros e não viáveis. Muitas éguas podem não demonstrar sinais clínicos de alteração placentária durante a gestação. Dessa forma, a avaliação da placenta no pós-parto e reconhecimento das características macroscópicas e histológicas são importantes para diagnóstico e prognóstico em neonatos de risco.
