| Summary: | Background: Among various foramina affecting alisphenoid
(greater wings of sphenoid), Foramen ovale (FO) and
Foramen spinosum (FS) are two important foramina
concerned to different advanced diagnostic and therapeutic
procedures involving middle cranial fossa like placement
of electrodes for EEG analysis, trigeminal radiofrequency
rhizotomy, microsurgical procedure using middle meningeal
artery as graft etc.
Objective: FO and FS vary in shape and size. That’s why;
we performed this study to provide data from the region of
West Bengal, India.
Methods: Forty adult human skulls having 80 intact greater
wings collected from different medical colleges in Kolkata
were meticulously examined for both morphologic and
morphometric parameters about the foramina like shape,
anteroposterior diameter, transverse diameter, any bony
outgrowth affecting their margins by digital photographs
and electronic caliper.
Result: Regarding FO, it was not classically oval in 42.5%
cases, somewhere it was irregular (6.25%) or semilunar
(2.5%) also. FS other than variation in shape and size was
found either partially (3.75%) or completely divided (5%).
Emissary sphenoidal foramen was also observed in 5%
cases. Appropriate statistical analysis was done.
Conclusion: Considering clinical importance, recognition
and knowledge of such possible variation will be
definitely helpful in the field of diagnostic medicine and
neurosurgery. |
