Estudios osteométricos del cráneo de las cabras rojas de Sokoto (Capra hircus): implicaciones para la anestesia regional de la cabeza / Osteometric studies of the skull of red Sokoto (Maradi) goats (Capra hircus): implications for regional anaesthesia of the head

The study involved the measurements of some clinically important landmarks for regional anesthesia in the head of twenty five Red Sokoto goats. The length and maximum height of the mandibles were 12.7cm and 7.7cm respectively. The distance from the mandibular foramen to the base of the mandible was 3.0cm while the distance between the lateral alveolar root and mental foramen and from the facial tuberosity to the infra-orbital foramen was 1.8cm in both instances. The data was discussed with regard to its importance in proper tracking of some nerves in aid of regional anaesthetic procedures in the head of the Red Sokoto goat and was compared with our results reported for the West African Dwarf breed.

El estudio abarca las medidas de algunas líneas clínicamente importantes para la anestesia regional en las cabezas de 25 cabras rojas de Sokoto. La longitud y altura máxima de las mandíbulas fue de 12.7cm and 7.7cm, respectivamente. La distancia del foramen mandibular a la base de la mandíbula fue 3.Oran mientras que, la distancia entre la raíz alveolar lateral y el foramen mental y entre la tuberosidad facial y el foramen infraorbital fue 1.8cm, en ambas instancias. Los datos fueron discutidos con respecto a su importancia en el tratamiento apropiado de algunos nervios, en la ayuda de procedimientos anestésicos regionales en la cabeza de la cabra Roja de Sokoto. Estos resultados fueron comparados con los reportados por nosotros para la cabra enana del Oeste africano.

Bilateral opening in the nasal bones of goats in Nigeria

The present study was performed to observe the morphological details of the skulls of the major goat breeds in Nigeria involving 28 Red Sokoto, 24 Sahel and 12 West African Dwarf goats. The study revealed the presence of a bilateral opening in the nasal bones of the skulls. This unique occurrence appeared in about 70 of the Red Sokoto, less than 10 of the West African Dwarf and did not occur in the Sahel goat skulls. It was suggested that the structure which displayed a high level of breed specificity may be contributing to the weakness of the nasal area of the face. This finding to the best of our knowledge is rarely described in the literature and will be important in breed identification of goats and can contribute to the migratory history of the species.
