“…This type of morphology can lead to compression of the vital structures passing through the FM. The mean area of the FM was 970.5mm² in our study which was similar to the observations made by Teixeria WR [17] while the mean of FM index was 87.68 similar to the Jain et al [18].…”

The foramen magnum is an important landmark located in the posterior part of the cranial base formed by the occipital bone. The purpose of this study was to evaluate the measurements of the foramen magnum in human dried skull and to note the variations in the shape and size of the foramen magnum. Additionally area and index of the foramen magnum were also calculated. Fifty human dried skulls of unknown age and sex were obtained from the department of CMCH Bhopal and FHMC Tundla. Foramen magnum were examined macroscopically for their different shapes. Anteroposterior and transverse diameters, foramen magnum area & foramen magnum index were measured. The foramen magnum shapes were determined as round shaped in 22%, oval shaped in 16%,egg shaped in16%, and irregular in18%,tetragonal in 12% penta and hexagonal 8% each. The mean A-P and transverse diameters of the foramen magnum was determined 38.75mm and 33.44mm respectively. In 4%of skull, the occipital condyle was observed to protrude in to the foramen magnum. The mean foramen index and foramen magnum area were 87.68 & 970.57mm². The data obtained may be useful to the neurosurgeon in analysing the morphological anatomy of craniovertebral junction in trans condylar approach for brain stem lesion.

The dimensions of the Foramen Magnum are surgically important because the compression of any structure passing through it can lead to severe complications. Materials and Methods: One hundred and five dried human skulls were classified as round, oval, and egg, pentagonal, hexagonal and irregular. The antero-posterior and transverse diameters were measured by using digital Vernier callipers. The Foramen Magnum Index was calculated by the formula: Anteroposterior diameter/ Transverse diameter. Results: In our study, the irregular shaped Foramen Magnum was found to be the highest in incidence. The mean antero-posterior and transverse diameters of the foramen magnum were recorded as 37.65 mm and 32.44 mm while the foramen magnum index was 88.68. Conclusion: The morphological and morphometric measurements of foramen magnum of skulls are of forensic importance. The neurosurgeons, orthopedicians and radiologists should be aware of these variations to avoid any complications during surgeries or any other procedures.
