Endovascular treatment is the treatment of choice for indirect carotid cavernous fistulas (CCFs). Direct surgical obliteration of CCFs is recommended in highly symptomatic patients or in those with an aggressive pattern of venous drainage. However, this is a technically challenging approach associated with significant procedural morbidity. The authors present a case in which they decided to attempt a novel access to the cavernous sinus through the foramen ovale before recommending surgery for an otherwise untreatable dural CCF. This 52-year-old man with an indirect CCF and neurological deficit had undergone several attempts to embolize the shunt by means of the standard approaches. Ultimately direct cavernous sinus access was obtained through the foramen ovale, resulting in complete obliteration of the shunt. The occlusion was radiographically stable at the 6-month follow-up evaluation, and the patient has remained asymptomatic. Percutaneous transovale puncture of a CCF is a feasible alternative to accessing the cavernous sinus when traditional transvenous catheterization or direct superior ophthalmic vein approach is not possible.

“…Multiple factors are associated with trigeminal neuralgia including aging, multiple sclerosis, persistent viral infection of the trigeminal ganglion, as well as structural abnormalities compressing the ganglion (arterial or venous loops, tumors such as meningiomas, and cysts such as epidermoids). However, there is increasing evidence supporting that most cases are due to focal compression of the root entry zone of the fifth nerve at the pons by an aberrant arterial or venous loop 3,4 , leading to demyelination of trigeminal sensory fibers within either the nerve root or, less commonly, the brainstem. encouraged by our findings in a patient with both hemifacial spasm and TN in whom botulinum toxin (BT) was able to control both spasms and pain 5 , we treated 12 further patients with idiopathic TN, but no hemifacial spasm, to evaluate the analgesic effects of BT in the management of this disorder.…”

-Botulinum toxin has been thoroughly studied as a potential tool in the treatment of several pain syndromes. Therefore, we assessed the clinical effects of botulinum toxin type A injections in 12 patients with otherwise unresponsive idiopathic trigeminal neuralgia. Patients were infiltrated with 20-50 units of botulinum toxin in trigger zones. Those who presented with mandibular involvement were also infiltrated in the masseter muscle. The patients were assessed on a weekly basis using the Visual Analogic Scale for pain. Ten of our patients reported a significant benefit from botulinum toxin injections, with reduction or even disappearance of pain, and remained pain free for as long as 60 days. Our findings suggest that botulinum toxin may represent a useful therapeutic tool in the management of patients with this entity.Key wOrdS: trigeminal neuralgia, botulinum toxin, facial pain.

Por lo tanto, evaluamos los efectos clínicos de la aplicación de toxina botulínica tipo A en 12 sujetos con neuralgia trigeminal idiopática resistente a manejo farmacológico. Se aplicaron en dichos sujetos entre 20 y 50 unidades de toxina botulínica tipo A en las zonas gatillo. Además se infiltró el músculo masetero en aquellos que presentaban involucro mandibular. Los sujetos fueron evaluados semanalmente con una escala visual análoga para dolor. diez de los sujetos reportaron un beneficio significativo con el uso de toxina botulínica, con reducción e incluso desaparición del dolor, permaneciendo libres de dolor por un periodo de hasta 60 días. Nuestros hallazgos sugieren que la toxina botulínica puede representar una herramienta terapéutica útil en el manejo de pacientes con esta entidad.PALABrAS-cLAVe: neuralgia trigeminal, toxina botulínica, dolor facial.

“…However in our study the differences in size and morphology between the left and right sides are not statistically significant pointing to a multifactorial cause of trigeminal neuralgia (Bowsher, 1997). Access to the foramen ovale through Hartel´s procedure (transfacial techniques) requires anatomical knowledge of three surface landmarks, zygomatic point, pupil point and cheek point.…”

Morphology and Location of Surface Landmarks of Foramen Ovale in Kenyans

SUMMARY: Foramen ovale is a surgically important aperture of the skull since it allows approach to and manipulation of the trigeminal ganglion as it lies in the Meckel's cave. This transfacial approach, Hartel's approach, requires two anatomical points for accurate cannulation; the zygomatic point and the pupil point. This study describes the morphology and location of foramen ovale and describes the pupil point in relation to the medial canthus in the Kenyan population. Department of Human Anatomy departmental review board approved the study. Two hundred dry skulls from the Department of Human Anatomy were studied using a digital calliper with help of a measuring frame. The results were analysed using SPSS version 20. The results showed the length and width of right foramen ovale was 7.69 mm mean (SD ±1.31) and 4.24 mm (±0.64) respectively while the left foramen ovale was 7.68 mm (±1.23) and 4.28 mm (±0.74). The distance of the zygomatic point from the external auditory meatus on the right was 23.54 mm (±2.26) and the left was 23.49 mm (±2.16). The median distances of the pupil point in relation to the medial canthus was 9.5mm on the right and 8.1 mm on the left. These results were significantly different from other population data. Neuronavigational aids to foramen ovale in Kenyans should take this into consideration.
