SURGICAL ANATOMY OF SOME NERVES OF THE HEAD AND THEIR MODE OF BLOCKING IN GOATS

The anatomical study was carried out on six heads of adult goats of both sexes. They were injected with 10% formaline solution. Careful dissection of the maxillary and mandilulo-alveo lar nerves and determination of the site of their blocking. Nerve block was carried out on six alive balady goats. From the obtained results of the present investigation, it was clear that the accurate position to block the infra-orbital nerve was through the infra-orbital formen, which can be easily palpated. However the mental nerve can be blocked through the mental foramen, while is difficult to palpate.
The area of desenstization included the dental pad, the first two premolar cheek teeth in upper jaw, the incisors and first premollr cheek tooth in the lower jaw. Desenstization of the whole upper and lower jaws together with their cheek teeth was obtained by blocking the maxillary and the mandibulo-alveo lar nerves.
The effect of the local anaesthetic began 10 minutes following injection, and the duration of anaesthesia lasted 70 minutes.
