Introduction: Study on Morphometric and radiological aspect
on existence of foramen of civinini. Sphenoid bone comprises
of some rare ossified ligaments, may encounter difficulty in
surgical procedures. Incidence of Pterygospinous bars various
with different racial groups and they are genetically controlled.
Complete ossification of pterygospinous ligament form foramen
of civinini. Entrapments of vessels or nerves may occur due to
existence of pterygospinous bar. The bar may locate medially
or inferiorly to formen ovale as seen in Hawaiian and lemurs.
Co–existence of bar with the wide lateral pterygoid plate
exhibits development of the bar from herbivore, carnivore and
old world monkeys. Comparatively absence or small spine of
civinini noted in new world monkeys, rodents and platyrrhines.
Pterygospinousbar represents the phylogenetic remnant of
Human beings.
Material and Methods: By using digital vernier caliper, the
measurements of length, width of the pterygospinous bar and
area of foramen of civinini including the length and breadth
of lateral pterygoid plate were measured. Using X–rays the
radiological view was determined.
Results: In this study from 160 cases of skull and sphenoid
bones revealed that complete and incomplete foramen of civinini
in 1.25% and 7.5% of cases respectively. Peculiarly accessory
foramen of civinini noticed in 1.25% of cases. Maximum area of
foramen of civinini was 94.2mm2
. The maximum width of lateral
pterygoid was noted as 19.6mm respectively. Mentocoronal
view of skiagram clearly shows the bar.
Conclusion: During Anaesthesia for trigeminal neuralgia may
encounter difficult to pass the needle. The bar compress the
mandibular nerve branches can cause lingual numbness,
pain and speech impairment. Conductive anaesthesia on the
mandibular nerve through the lateral subzygomatic route may
be difficult to approach. Exploring the anatomical and clinical
updates of pterygospinous bar may guide the surgeons and
radiologists to overcome any difficulties in infratemporal and
para or retropharyngeal regions. |
