This would make Sukhbir Singh Badal the second member of the Badal family to contest the polls-—his wife, Harsimrat Kaur Badal, is set to seek mandate from one of the two seats. ET EnergyWorld A one stop platform that caters to the pulse of the pulsating energy. Mastoidectomy has been done preserving the tip, and vertical mastoid segment of facial nerve is visible with the origin of chorda tympani nerve. Removing middle turbinate from one side and lateralizing on the other side can create this. Vodafone Business Services Digilogue – Your guide to digitally transforming your business.

Vertebrobasilar junction is visible with the origin of anterior spinal artery.

Transverse foramen of axis faces superolaterally, thus permitting the lateral deviation of the vertebral artery as it passes up to the more widely separated transverse foramina in the atlas. In the present anatomical study, we have described the relation of critical neurovascular structures such as vertebral artery VA and lower cranial nerves in relation to various bony and muscular landmarks from anterior, posterior, and lateral corridors.
In the transtubercular variant of the supracondylar approach, the prominence of the jugular tubercle that blocks access to the area in front of the IX, X, and XI cranial nerves is removed extradurally to increase visualization of the area in front of the brainstem and to expose the origin of a PICA that arises from the distal part of the VA near the midline.
The cancellous bone within the occipital condyle has been drilled away while preserving the cortical and articular surfaces to expose the XII nerve in the hypoglossal canal [ Figure 7d ]. Sometimes, it has been used for intradural lesion too. This article has been cited by other articles in PMC. This part of lower cranial nerves is anterior to rectus capitis lateralis muscle as can be seen here. The OC1 joint and the posterior condylar emissary vein are exposed along with C2 ganglion. Bone was removed widely extending from external occipital protuberance and superior nuchal line to foramen magnum.
Transverse ligament is broad in middle and tapered laterally. This bend is also intimately related to the medial side of RCLa muscle. After coming out, it joins internal carotid artery for a short distance before passing anteriorly to supply pharyngeal sensory and muscular branches.

National Center for Biotechnology InformationU. Have sukhdee read these stories? This would make Sukhbir Singh Badal the second member of the Badal family to contest the polls-—his wife, Harsimrat Kaur Badal, is set to seek sukhseep from one of the two seats. The apical ligament of the dens has a broad cartilaginous base that arises on the apex of the dens and extends to the anterior border of foramen magnum [ Figure 2h ].
Atlas is the first cervical vertebra with two lateral masses formed by superior and inferior articular facets, which are connected in front by a short anterior arch and behind by a longer curved posterior arch.
Their articular surfaces are convex, face downward and laterally, and articulate with the namee facet of atlas. Clivus is divided into three parts: On the sukbdeep side, posterior wall of maxillary sinus in front of infratemporal fossa is still visible.
Supracondylar groove is drilled exposing hypoglossal canal and jugular tubercle. Jugular tubercle was removed on one side to give a comparative view against the other side. Retracting cerebellar hemisphere at this stage gives a view of anterolateral brainstem with lower cranial nerves [ Figure 7f ].
The flocculus and the choroid plexus protruding from the foramen of Luschka behind the rootlets of the IX and X nerves and the VII, VIII nerve complex arising from the brainstem anterosuperior to the foramen of Luschka may be seen in the transnasal exposure [ Figure 3c ].
A study based on surgically treated patients. Hence, RCLa, posterior belly of digastric muscle, occipital condyle, jugular process, hypoglossal canal, and jugular tubercle are useful bony and muscular landmarks to be identified in this dissection of lateral corridor.
Craniovertebral junction 360°: A combined microscopic and endoscopic anatomical study
Access to clivus, foreman magnum, occipital cervical joint, odontoid, and atlantoaxial joint was studied anteriorly with an endoscope. Endoscopic anatomy of sukhreep pterygopalatine fossa and the transpterygoid approach: The clivus is the place of attachment of longus capitis and the rectus capitis anterior. The atlanto-occipital joints are seen here in the anterior aspect of foramen magnum. Supracondylar bone is drilled with jugular tubercle.
Splenius capitis is broad, flat muscle present deep to sternocleidomastoid and inserted along mastoid process of the temporal bone and into the rough surface on the occipital bone just below the lateral third of the superior nuchal line.
Jugular foramen is opened and venous injection is removed showing IX nerve passing superiorly in a separate subcanal. Occipital condyles, transverse process of atlas, and jugular tubercle are main bony landmarks in lateral corridor whereas RCLa and posterior belly of digastric muscle are the main muscular landmarks.
Layers of muscles, ligaments, and membranes support bony complex of occiput, atlas, and axis from all around which helps in adding mobility as well as stability to this critical area.
