The present study aimed to study the clinical anatomy of the maxillofacial and mandibular regions of the Madras Red sheep through the morphometric analysis of some clinically important parameters pertaining to the regional anesthesia. The study was conducted in 20 males and 20 female adult Madras Red sheep around 20-25 kg BW. Eleven parameters related to the clinical regional anesthesia of the maxillofacial and the mandibular regions were recorded. The distance between the facial tuberosity to the infraorbital canal was 2.25 ± 0.14 cm in males and 2.14 ± 0.15 cm in females. The distance from the infraorbital canal to the root of the alveolar tooth was 1.73 ± 0.28 cm in males and 1.73 ± 0.13 cm in females. The length and height of the mandibles were 15.37 ± 0.56 cm, 9.00 ± 0.24 cm and in males 14.53 ± 0.24 cm, 9.68 ± 0.16 cm in females respectively. The maximum height of the mandible to the coronoid process, width or height of the mandibular foramen and the distance from the condyloid process to the base of the mandible were recorded as 9.0 ±.24, 0.82. ± 0.05, 6.68 ±0.19 cm in males and 9.68 ± 0.16, 0.83 ± 0.04, 6.25 ± 0.28 cm in females respectively. The present study revealed that most of the parameters showed statistically significant difference between the sexes i.e. the males are having higher values. However, considering from the practical point of view, these differences were meager. The results were discussed with regard to their clinical applications in various regional anesthesia performed in maxillofacial and mandibular regions of the Madras Red sheep.
