AbstractA patient presented with mild upper airway obstruction after being shot from behind through the neck and soft palate. Two days later he developed palsies of the IXth to XIIth cranial nerves inclusive on the traumatised side. These palsies resolved spontaneously after three weeks. Further investigation revealed the presence of a saccular aneurysm of the internal carotid artery. The internal carotid artery was ligated after gradual closure for three days using a Preston clamp.

Internal Carotid Artery Aneurysm

The extracranial internal carotid artery aneurysm (EICAA) is an uncommon arterial lesion. Patients typically present with neurologic symptoms resulting from impaired cerebral perfusion and compression symptoms of cranial nerves. Often EICAA presents as a pulsatile neck mass, which is otherwise asymptomatic. We present a case of an 84-year-old female, who was initially referred to the Emergency Department for Otolaryngology with suspected peritonsillar abscess. The patient had a history of recent upper airway infection and cardiovascular comorbidities, including hypertension and ischaemic stroke complicated by extensive neurologic deficits. Physical examination revealed a compact, nonpulsatile mass in the lateral parapharyngeal space and local erythema of the mucosa. Duplex Doppler Ultrasonography and Computed Tomography revealed an atherosclerotic aneurysm of the right internal carotid artery, measuring63×55×88 mm, stretching from the skull base to the angle of the mandible.

Abstract Objective: Access to the high cervical internal carotid artery (ICA) is technically challenging for the treatment of lesions in and around this region. The aims of this study were to analyze the efficacy of approaching the high cervical ICA through the retromandibular fossa and to compare preauricular and postauricular incisions. In addition, the relevant neural and vascular structures of this region are demonstrated in cadaveric dissections. Methods: The retromandibular fossa approach was performed in four arterial and venous latex-injected cadaveric heads and necks (eight sides) via preauricular and postauricular incisions. This approach included three steps: 1) sternocleidomastoid muscle dissection; 2) transparotid dissection; and 3) removal of the styloid apparatus and opening of the retromandibular fossa to expose the cervical ICA with the internal jugular vein along with Cranial Nerves X, XI, and XII. Results: The posterior belly of the digastric muscle and the styloid muscles were the main obstacles to reaching the high cervical ICA. The high cervical ICA was successfully exposed through the retromandibular fossa in all specimens. In all specimens, the cervical ICA exhibited an S-shaped curve in the retromandibular fossa. The external carotid artery was located more superficially than the ICA in all specimens. The average length of the ICA in the retromandibular fossa was 6.8 cm. Conclusion: The entire cervical ICA can be exposed via the retromandibular fossa approach without neural and vascular injury by use of meticulous dissection and good anatomic knowledge. Mandibulotomy is not necessary for adequate visualization of the high cervical ICA.

Extradural Space

Abstract The so-called cavernous sinus is a venous pathway, an irregular network of veins that is part of the extradural venous network of the base of the skull, not a trabeculated venous channel. This venous pathway, the internal carotid artery, and the oculomotor cranial nerves cross the medial portion of the middle cranial fossa in an extradural space formed on each side of the sella turcica by the diverging aspects of a dural fold. In this space the venous pathway has only neighborhood relations with the internal carotid artery and the cranial nerves. The space itself must be distinguished from the vascular and nervous elements that it contains. The revision of the anatomy of this region has not only theoretical interest but also important clinical implications.

Artery Disease

Carotid artery disease leads to stroke in 30% of cases. The total frequency of carotid artery deformations varies from 10 to 40% depending on the results of angiographic and pathological examinations. Coiling of the internal carotid artery is associated with embryological pathology, and elongation and inflection are the result of fibromuscular dysplasia or changes that are accompanied by atherosclerotic damage to the arteries. Kinking – an artery bend at an acute angle. It can be congenital, when from early childhood there is a violation of cerebral circulation and develops over time from an elongated carotid artery. The formation of inflections contributes to hypertension, the progression of atherosclerosis. Coiling – the formation of a loop of an artery. Despite the smooth running of the loop, the changes in bleeding in it are significant. The nature of bends in coiling can vary depending on body position, blood pressure. The most common is the elongation of the internal carotid or spinal artery, which leads to the formation of smooth curves along the vessel. Elongation of the arteries is usually detected in random studies. The main etiological causes of pathological tortuosity of the internal carotid artery include: congenital deformation of the vascular wall, hypertension, osteochondrosis of the cervical vertebrae, compression of the bracheocephalic arteries, cranial nerves. The review article deals with anatomy and topography of the major vascular-nervous bundle components of the neck on the stages of early ontogenesis from the point of view of surgical correction of departures from their normal development in newborns and children of an early age. However, literary data are controversial and fragmentary concerning anatomical peculiarities of the carotid arteries, internal jugular vein, and vagus. The facts concerning synoptic correlation of the major vascular-nervous bundle components of the neck in fetuses and newborns are not systematized. Carotid artery disease leads to stroke in 30% of cases. The total frequency of carotid artery deformations varies from 10 to 40% depending on the results of angiographic and pathological examinations.

Cranial Nerve Palsies

Internal carotid dissection most commonly presents as headache, focal neurological deficits or stroke. Rarely it can manifest itself by causing a palsy of the lower cranial nerves (IX, X, XI, XII). The reported incidence of isolated cranial nerve palsies is rare. We report a case of an internal carotid artery dissection manifesting as isolated XII (hypoglossal) cranial nerve palsy.

Abstract Background and Aim The specific anatomical triangles around the cavernous sinus are frequently explored areas in neurosurgeries and thus require a methodical approach keeping in mind the possibility of variational anatomy and morphometric differences. One of the most inconsistent triangles is the Glasscock’s (posterolateral) triangle (GT) in the middle cranial fossa. Materials and Methods The present study was undertaken on 26 skull bases of the middle cranial fossa from cadavers and 42 dry adult skulls from the departmental collection to analyze parameters of the GT pertinent to the horizontal intrapetrosal segment of the internal carotid artery. The measurements of all sides of the GT were done and the mean surface area was calculated using Heron’s formula. The findings of the study were compared with earlier works where other methods of investigation were employed, such as, dry bones/computed tomography scans, cadaveric studies. Observations The GT in the present study had a mean surface area of 43 mm2. The study presented with variable morphological and morphometric data as compared with earlier studies. The scientific attribute to the differences in parameters is presumably relevant to the racial differences as well as the pathophysiological condition of the subject. Conclusions Surgical interventions to the base of the skull have evolved enormously over the years. Earlier studies have described the triangle on cadaveric specimen. We have attempted to revisit the area in cadaveric as well as dry skull base. Flawless information of the area under surgery augments safer procedures and reduction in the damage to brain tissue as well as the cranial nerves. The putative clinical implications of the present study are useful in helping in high precision surgeries and enhanced patient care. The highly variable GT needs to be understood properly for a desired culmination in ICA exposure in the intrapetrosal segment.
