The morphometrics and typology of the skull in the Ghanaian local dog of non-descript breed (Canis lupus familiaris) / Morfometría y tipología del cráneo en el perro local de Ghana de raza no definida (Canis lupus familiaris)

The shape of the head is considered the most important criterion in determining the standard breeds of dogs. It is of much significance to study the skull typology of the Ghanaian local dog in order to establish a template of its identification as a breed and to generate data which could be useful in the comparative anatomy of the skulls of dogs. A total of twenty skulls of adult dogs of two age groups were used in this study. 31 parameters were measured and 6 skull indices were calculated on their basis. The group of skulls from older fully grown dogs showed higher values in all parameters. Results of the current study will provide baseline reference data on skull parameters of local dolichocephalic dogs. More importantly, results obtained could be useful in veterinary applied anatomy and clinical practice in areas including forensic medicine, plastic or cosmetic maxillofacial surgery, neurosurgery of the cranium, acupuncture, nerve block and other clinical manipulations involving the head.

La forma de la cabeza se considera el criterio más importante para determinar las razas estándar de perros. Es relevante estudiar la tipología del cráneo del perro local de Ghana para establecer una plantilla de su identificación como raza y generar datos que puedan ser útiles en la anatomía comparativa de los cráneos de perros. En este estudio se utilizaron un total de veinte cráneos de perros adultos de dos grupos de edad. Se midieron 31 parámetros y se calcularon 6 índices de cráneo sobre la base de ellos. El grupo de cráneos de perros mayores completamente desarrollados mostró valores más altos en todos los parámetros. Los resultados del estudio actual proporcionarán datos de referencia sobre los parámetros del cráneo de los perros dolicocefálicos locales. Más importante aún, los resultados obtenidos podrían ser útiles en la anatomía veterinaria aplicada y la práctica clínica en áreas que incluyen medicina forense, cirugía plástica o cosmética maxilofacial, neurocirugía del cráneo, acupuntura, bloqueo nervioso y otras manipulaciones clínicas que involucran la cabeza.

Comparison of lambdoid suture closure by X-Ray and CT scan in two states of India.

In the present study, herewith comparison is done for closure of squamous suture of skull of living individuals from Punjab and Rajasthan. The cases studied in Punjab are 100 individuals between the age group of 45 years to 70 years with age interval of five years and twenty cases from each age group were studied who were CT scanned for closure of squamous suture at Rajindra Hospital Patiala (Punjab). In Rajasthan (SMS Hospital Jaipur), X-ray examination of 100 individuals was done having age group 40 years to 70 years with age interval of ten years in male and female separately for squamous suture closure and accordingly the squamous suture is divided into 2 parts-(1) Upper half(½), (2)Lower half (½). In both studies, squamous suture is studied ectocranially. It is seen that endocranially suture closure will not give reliable results and sometimes endocranially sutures remain unfused for whole life. No differences in right or left side of squamous suture have been reported by Todd and Lyon. Occasionally there is considerable sclerosis and condensation along the various sutures, particularly sagittal, squamous and coronal suture.
