The identification of mastoidal emissary veins is of importance in the neurosurgical practice to diagnose abnormal and normal structures. In the present study, the objectives were to estimate the prevalence rate of mastoidal emissary foramina in the temporal bones of the adult skull and to study their number and morphology. The present study included 48 adult human skulls which were obtained from the gross anatomy laboratory of our institution. The mastoid parts of 96 temporal bones were macroscopically observed for the prevalence, number and morphology of the emissary foramina. It is observed that, the mastoidal emissary foramen was present in 88 temporal bones (91.7%) of our specimens. The foramen was observed single in 60 temporal bones (62.5%), double in 22 bones (22.9%), and triple in 6 temporal bones (6.2%). The mastoidal emissary foramen was absent in 8 (8.3%) temporal bones. The foramen was bilaterally absent in 3 (3.1%) skulls. It was unilaterally absent in 2 (2.1%) skulls and both were on the left side. The mastoidal emissary vein is prevalent in a large number (91.7%) of cases. It was observed that the accessory mastoidal emissary foramina were present in 29.1% of cases. Recognition of the mastoid emissary veins and accessory mastoid emissary veins during the otologic surgery is critical to avoid the significant bleeding. In the neurosurgical practice, the knowledge is important due to variability in the number of mastoidal emissary veins and their connection to the venous sinuses.

The objectives of the present study were to study the prevalence of the parietal emissary vein in adult South Indian population and to study the distance of foramen from the sagittal suture. There were 58 adult human skulls in the present study which were available at the anatomy department of our institution. The study included 116 parietal bones which have been observed macroscopically for the number, prevalence and topography of the emissary foramen. The emissary foramen was present in 83 parietal bones (71.5%) of the present study. It was present at the junction between the middle 1/3 and posterior 1/3 region of the parietal bone. The foramen was observed solitary in 73 parietal bones (62.9%), double in 8 bones (6.9%), and triple in 2 parietal bones (1.7%). The foramen was not observed in 33 parietal bones (28.4%). The bilateral absence of parietal emissary foramen was seen in 7 skulls (12.1%). It was absent unilaterally in 19 skulls (32.7%). The accessory foramina were seen in only 8 skulls (13.8%). The mean distance of the foramen from the sagittal suture was 6.7±2.9 mm and 6.8±2.8 mm on the right and left sides respectively. The prevalence of parietal emissary vein in the present study was 71.5%. The present study has observed important data about the morphology and morphometry of the parietal emissary vein in South Indian population. The identification of parietal emissary veins and accessory veins is important in the operation room to prevent the blood loss.

Introduction & object : Mastoid emissary vein (MEV) complex is one of the superficial venous systems of posterior neck. It could be a potential source of bleeding during flap elevation or might be an obstacle to bone work for hearing device surgery. The objective of this study is to evaluate the morphometric analysis of MEV complex using 3-d reconstruction of temporal bone CT. Materials & Method : From the normal adults TBCT aged from 20 to 60, twenty identifiable MEV cases without history of head trauma, otitis media, neurological disease, and skull surgery including mastoid surgery were evaluated. Morphometric parameter of MEV angle from sigmoid sinus, the length of MEV from the branch of sigmoid sinus to the bony aperture mastoid bone, distance from mastoid tip to the bony aperture of MEV, distance from asterion to the bony aperture of MEV, distance from asterion to mastoid tip, perpendicular length from bon aperture of MEV to the imaginary line which pass asterion and mastoid tip, perpendicular length from bon aperture of MEV to the imaginary temporal line. Conclusions : Preoperative evaluation of MEV is recommended for the retrosigmoid bone work or periosteal flap elevation. Three dimensional reconstruction of MEV might helpful for the imaginary information for the surgeon.
