Decompression endoscopic surgery for frontal secondary headache attributed to supraorbital and supratrochlear
nerve entrapment: a comprehensive review.
The supraorbital and supratrochlear
arteries emerge superficially at or near the supraorbital foramen to supply the forehead, and anastomose with the frontal branch of the superficial temporal and the supraorbital and supratrochlear
arteries of the opposite side (Fig.
cylindricum based on the following diagnostic characters (Gillette and Ray 1981): the direction of the alar processes of the atlas, the absence of the supratrochlear
foramen, the transverse processes of the last sacral vertebra, the anterior surface of the characters of the pelvis and the ilium, the overall number of peripheral figures, and the proportion between the diameter of the central figure and the total diameter of the osteoderms.
89) One medium-term report showed that patients with type B and D trochlear dysplasia benefitted more from trochleoplasty than those without a supratrochlear
In some cases it is represented by ligament of Struther which extends from an occasional bony projection called supratrochlear
spur; from the anteromedial surface of the lower part of the humerus to the medial epicondyle.
The supraorbital vein unites with the supratrochlear
vein near the medial angle of the eye to form the facial vein.
Most of the operations were carried out under general anesthesia and in unfit patients, local anesthesia by using lidocaine 2% with adrenaline 1:80000 to block the supratrochlear
and infraorbital nerves.
All patients underwent ultrasonic and dopplerography of brachycephalic trunk examination (UDBT) of common carotid artery (CCA), internal carotid artery (ICA) and supratrochlear
artery, including transcranial dopplerography examination (as well as study of hemodynamic of medium cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) by using "LOGIDOP-4" device (made by "Kransbuchler", Germany) equipped with 2.
the following nerves were blocked bilaterally: the supraorbital and supratrochlear
nerves were blocked as they emerge from the orbit with 2 ml of solution using a 23G needle introduced above the eyebrow perpendicular to the skin; the auriculotemporal nerves were blocked with 2 ml of solution injected 1.
, zygomaticofacial, auriculotemporal, greater auricular, greater and lesser occipital nerves were blocked using 20 ml of 0.
Other complications of FST include (1) supratrochlear
and supraorbital nerve and vessel injury with resultant hypoesthesia of the ipsilateral forehead and scalp, (2) poor wound healing, and (3) possibly hypertrophic scarring.
