Micro-computed tomography study of the abnormal osseous extensions of sella turcica

Bilateral Extensive Ossification of the Posterior Petroclinoid Ligament: An Anatomical Case Report and Literature Review

“…9 However, only a few cadaveric studies have been conducted to estimate the true incidence of petroclinoid ligament ossification, with most results obtained from radiographic studies. A micro-computed tomography study by Skrzat et al 24 of the abnormal osseous extensions of the sella turcica in the skull of a woman found that "ossification around the dorsum sellae supported by strong mineralisation of the bony structure suggests that it might have been a congenital anomaly." Some authors suggest, however, that formation of the osseous abnormalities within the skull may have an endocrinologic or metabolic association.…”

“…Some authors suggest, however, that formation of the osseous abnormalities within the skull may have an endocrinologic or metabolic association. 24 One of the very few such anatomical studies based on wet specimens was performed by Kimball et al 4 on 15 human adult formalin-fixed midsagittally hemisected cadaveric heads, the age of the donors ranging from 68 to 93 years, as well as on 71 dry human skulls. The authors introduced a new term, the petroclinoid bone, to describe a bony bridge over the trigeminal notch, and they described it as a remnant of an ossified posterior petroclinoid dural fold.…”

Morphometric analysis of the sella turcica in Turkish individuals with different dentofacial skeletal patterns

“…One study stated that the massive ossification of the dura mater extended to the dorsum of the sella turcica, and the posterior clinoid processes could alter the morphology of the sellar region [37]. Camp (1924) classified the sella turcica as circular, oval, and flattened.…”

Osseous Bridges of the Sphenoid Bone: Frequency, Bilateral and Sex Distribution

“…A complete CcB enclosing the CcF, has been reported to occur with varying frequency in different populations: India—3.0% [ 9 ] and 5.2% [ 7 ]; South Korea—4.1% [ 11 ]; Bosnia and Herzegovina—7.0% [ 13 ]; Nepal—8.6% [ 15 ]; Italy 8.7% [ 21 ]; Turkey—8.8% [ 18 ] and 15.0% [ 22 ]; UK—10.0% [ 14 ]; Poland—16.3% [ 23 ]; USA—20% [ 1 ], 31.0% [ 2 ] and 41.8% [ 24 ]; and Greece—20.4% [ 20 ] and 23.6% [ 19 ]. A previous investigation of Bulgarian males from the beginning of the 20th century [ 25 ] has reported a frequency of 8.2% (9 out of 110 dry skulls) for the CcF.…”
