The mastoid process is a bony projection on the temporal bone, it is located behind external acoustic meatus ears on each side of your skull. Due to its location, ear issues, such as a middle ear infection, can cause pain at the mastoid process. This bone also provides an attachment point for several muscles. This study aimed to evaluate the anatomical variations of mastoid canal and mastoid grooves. The present study was conducted in 138 adult dry skull belongs to Karnataka region collected from multiple medical institution. All the skulls were examined carefully and studied for the presence of mastoid canals and grooves. The skulls which were having canals and able to pass metal probe considered as possessing mastoid canals. We have recorded length and number of mastoid canals, bilateral, right unilateral and left unilateral appearance also recorded. We also recorded about grooves morphology. Mastoid canals were found in 89 (64.49%) out of the 138 skulls, we have seen mastoid canals either unilaterally or bilaterally. Out of the 89 skulls where we have found mastoid canals, in 26 (18.84%) skulls mastoid canals were bilateral, in 16 (11.59%) skulls we have found in unilateral right side, in 40 (28.98%) skulls we have found in unilateral left. In 26 (18.84%) skulls we have seen mastoid grooves out of 138 skulls, out of 26 skulls in 5 (3.62%) skulls grooves were bilateral, in 12 (8.69%) skulls right unilateral, in 9 (6.52%) skulls left unilateral. The present study concludes that mastoid canals and grooves morphological variations may help otolaryngologists and neurosurgeon’s surgical procedures which involve access to structure in posterior cranial fossa and mastoid air system.
