They cover, anterior cranial fossa, nasal cavity, and paranasal sinuses; the sellar, parasellar, and clival
region; cerebellopontine angle and jugular fossa; petroclival and lateral skull base; open and endoscopic approaches to the sinonasal cavity and skull base; post-treatment appearance following skull base therapy; and neuroendovascular procedures for skull base neoplasia.
When undertaking resection of a tumor in the clivus, the clival
bone removal by drill needs careful attention because the dura behind the clivus is very thin and usually adheres to the clival
On CT, an expansile osteolytic lesion is seen involving clival
occipital bone (basiocciput) with multiple areas of end-osteal scalloping and marginal sclerosis, suggestive of chronicity.
Was considered in view of clival
location; however, the characteristic large physaliferous cells were not evident and we ruled out the same.
However, on imaging, other processes were included in the differential diagnosis, among them inflammatory processes, which in our case proved on biopsy to be an unusual clival
osteomyelitis extending into the sphenoid sinus.
Further classification of complete clival
canal includes superior, inferior and bifurcated.
Nosotros somos del criterio que existen solo 2 condiciones en las cuales seria necesaria la apertura del seno esfenoidal para un mejor acceso al polo superior del tumor, una de ellas es cuando la lesion craneo-espinal tiene una extension rostral por encima de la sincondrosis occipito-esfenoidal y la otra, en los raros casos donde existen senos esfenoidales con gran extension clival
de la neumatizacion.
The anthropometric measures included the glabella-opisthocranion , nasion-dorsum sellae , dorsum sellae- opisthocranion , nasion-basion , nasion-opisthion , basion-opisthion , prosthion-basion , basion-vertex  and the clival
inflammation with cavernous sinus trombophlebitis and orbital subperiosteal abscess.
This edition has new illustrations and new chapters on sudden unilateral neuralgiform conjunctival injection tearing headache, primary thunderclap headache, hypnic headache, nummular headache, atypical odontalgia, burning mouth syndrome, nervus intermedius neuralgia, red ear syndrome, clival
chordoma syndrome, glomus tumor of the shoulder, osteonecrosis of the elbow joint, driver's elbow, boxer's knuckle, trigger wrist, superior cluneal nerve entrapment syndrome, clitoral priapism, breaststroker's knee, glomus tumor of the knee, and fabella syndrome.
chordomas represent approximately half of cranial chordomas and they are more likely to occur in women and younger patients.
After this, a corridor was drilled medial to the ICA and lateral to the clival
dura to gain access to the lesion.
