The findings of the present study provided a detailed understanding of th. There was a similarity between the Indian and Turkish dry temporal bones in terms of distance from the PAI to the SSPS (7-8 mm) and SSS (19-20 mm) (p = 0.01) and prevalence of morphology of PAI (oval and elliptical) (p = 0.04, p < 0.05). The internal auditory canal must be exposed through 270 of its. styloideus Atlas of Human Anatomy, 15th Ed. However, outmaneuvered and defeated by Alexander the Great, he was wounded and taken captive. In the battle of the Hydaspes (Jhelum River) in 326 B.C., Porus, at the head of a great army that included many war elephants, offered strong resistance to a Greco-Macedonian invasion. mastoideus Sobotta Ossicula auditu5 Cavitas tympani Labyrinthus vestibularis Labyrinthus cochlearis Membrana tympanica Tuba auditiva auditoria Proc. King of an ancient Indian state in central Punjab. On both sides, round PAI were identified more frequently than elliptical ones (32 26.6% (left) 39 32.5% (right)) (p < 0.05). The canal is initially identified in its midsection and towards the porus acusticus. Porus acusticus internus Os temporale Auricula Meatus acusticus externus proc. Forty-three (35.8%) elliptical (or transverse) and 77 (64.1%) oval (or round) PAI were detected in the Turkish dry temporal bones.

Their horizontal diameter (HD), vertical diameter (VD), shape, prevalence of the shapes of PAI, and the distance from the sulcus for the sigmoid sinus (SSS), sulcus for superior petrosal sinus (SSPS), and jugular foramen (JF) of dry Turkish temporal bones were recorded. One hundred twenty dry adult human temporal bones (61 male, 59 female) were investigated in the study. Therefore, we performed this study to elucidate further the relationship between the different morphologies of PAI and ethnicity and to discuss their effects on surgery. porus acusticus internus - meatus acusticus internus dno je fundus meatus acustici interni, kt. MRI showed a millimeter-sized tumor, located in the porus acusticus, developing perpendicular to the axis of the acoustico-facial nerves, surrounding them. We present two cases of hemangiomas located at the porus acusticus, an even more rare site. The influences of porus acusticus internus (PAI) on ethnicity and differences between populations have not been investigated so far. Hemangiomas near the geniculate ganglion or in the internal acoustic meatus are well known but rare.
