Involvement of nitric oxide synthase in the physiology and pathophysiology of facial nerve function and dysfunction

To date few reports have discussed the presence and function of nitric oxide (NO) in structures of the facial nerve. We performed nicotinamide adenine dinucleotide phosphate (NADPH-d)-diaphorase-histochemistry and immunohistochemistry on the intratemporal portion of the facial nerve, including the geniculate ganglion, of guinea pigs using specific antibodies to the three known isoforms of NO synthase and soluble guanylyl-cyclase (sGC). Normal facial nerves were compared to those treated intratympanically with bacterial lipopolysaccharides (LPS) and tumor necrosis factor-α (TNF-α). Both constitutive NOS isoforms and sGC could be detected in the bipolar ganglion cells of normal animals, while the inducible isoform (iNOS or NOS II) was not found. Endothelial NOS (NOS III) and sGC were present in blood vessels and were predominantly found in the perineurial sheath and less in the endoneurium. sGC could be detected in all fibers in a cross section of the facial nerve. LPS and TNF treatment led to the detection of iNOS in the perikaryia of the geniculate ganglion and the perineural sheath. These findings imply that NO may be involved in neurotransmission at least in the visceroafferent system. NO regulates vascular tone of nutrient blood vessels in the perineural sheath and endoneurium. The presence of sGC indicates that NO acts via its second messenger cGMP. NOS II expression may be a contributing factor to facial nerve palsy via two different mechanisms: NOS II-generated NO may lead to an overstimulation of the visceroefferent nerve fibers and motor fibers of the facial nerve. Dysregulation in facial nerve blood vessels could lead to edema and elevated pressure on the nerve within its osseous canal. Received: 13 April 1999 / Accepted: 12 August 1999     

Facial haemangioma,agenesis of the internal carotid artery and dysplasia of cerebral cortex: case report

We describe a girl with a facial haemangioma, associated with other vascular anomalies: agenesis of the internal carotid artery, cerebral cortical dysplasia and hypoplasia of the cerebral hemisphere on the same side of the angioma. We studied the patient by conventional arteriography, T1- and T2-weighted MRI and magnetic resonance angiography.     

内窥镜辅助下显微神经血管减压术治疗 特发性偏侧面肌痉挛

目的为进一步提高神经血管减压术治疗特发性偏侧面肌痉挛的疗效。方法经乙状窦后小骨窗开颅加用内窥镜辅助显微血管减压术治疗特发性偏侧面肌痉挛３５例。结果术后３４例症状消失,１例症状减轻,３５例随访６个月至３年半,术后面肌抽搐消失者３３例,１例症状减轻,１例１年后复发。结论内窥镜可弥补手术显微镜的不足之处,减少组织损伤和判断错误,提高治疗效果。     

Aesthetic Male Facial Skeletal Surgery

Craniofacial surgery concepts developed originally for reconstruction may also be applied to aesthetic surgery. The facial skeleton is an important component of appearance and may be modified using common craniofacial surgery techniques. Three representative male patients are presented, who each desired an improvement in his appearance. The techniques used were different and combined orthognathic and remodeling procedures. Aesthetic male facial skeletal surgery was beneficial in these selected cases. The results were well received and without complications. Surprisingly, we have found that male skeletal aesthetic patients did not have unrealistic expectations and were pleasant to manage pre- and postoperatively.     

Full-Face Laser Resurfacing and Rhytidectomy

The Ultrapulse CO₂ laser (Coherent Inc., Palo Alto, CA, USA) was used in 239 patients, from March 1996 to July 1998, for full-face laser resurfacing. In 106 (43%) of these patients rhytidectomy was performed in the same procedure. All patients submitted to laser resurfacing were prepared for 1 to 2 months beforehand with retinoic acid and hydroquinone. The procedures were done under local anesthesia controlled by an anesthesiologist. A clear film dressing impregnated with silicone gel (Silon TSR; Bio-Med Sciences, Bethlehem, PA, USA) was used for 6 to 7 days and complete healing was observed in 7 to 10 days. Complications were exclusively dermatologic, without relation to surgery. No necrosis of the cutaneous flap was observed. Skin biopsies of 10 consecutive patients undergoing the combined procedures revealed no vascular impairment to the dermis. The patients were able to resume their activities 2 weeks after the procedure.     

Facial pain

Summary In a prospective material of 1052 patients the precipitating factors, associated symptoms, psychological and neurological deficits have been examined.Mastication and talking are the most frequently occurring precipitating factors, 76% as regards Neuralgia, with typical starting difficulties. As regards Non-neuralgiform Pain 24%, with precipitation late in the masticatory process. There were trigger zones in 50% of the cases of Typical Trigeminal Neuralgia and in 9% of the patients with Non-neuralgiform Pain. In a series of cases the jaw joint is perceived as a trigger zone. Cold precipitates pain in 48%–39%. Other precipitating factors are much more rare-psychological stress in 15% of the patients with Non-neuralgiform Pain, however.Vegetative associated symptoms were relatively frequent, lacrimation occurred in 31% of the cases of Typical Trigeminal Neuralgia and in 20% of the cases of Non-neuralgiform Pain. Rhinorrhea and salivation were less frequent. In terms of figures migrainoid associated symptoms had no connection with vegetative associated symptoms or with pain in the eye.In 11 % of the patients pain occurred most frequently during the night and in 20% the frequency of pain was the same day and night. About 1/3 of the patients with Neuralgia experienced seasonal variations.Tenderness of foramina is a symptom of no significance. Very few patients had primary sensory loss. No eye or ear symptoms have been found which may be referred to as the patho-anatomical basis of the pain.About 1/3 of the patients with Non-neuralgiform Pain had psychological symptoms whereas hardly any patients with Neuralgia had them. MMPI test performed on a small matched material showed no difference between Neuralgia and Non-neuralgiform Pain.In material B an examination has been made of the jaw joint arthrosis symptoms. A restriction of the diagnosis of arthrosis has had the effect that it must be recognized that patients with facial pain do not have the high frequency of jaw joint diseases previously assumed. As was also the case in a series of normal material previously published, between 1/5 and 1/3 of the patients with Neuralgia had jaw joint arthrosis which was due to old age.This study has not revealed any connection between previous diseases, the onset of pain, the character and course of the pain, the character of the attack, the localization of pain, precipitating factors, associated symptoms and symptoms of loss on the one hand and the patho-anatomical substratum on the other.The psychological examinations were performed by Mr. Peter Bruun, chief psychologist, for whose cooperation I am grateful.     

Evaluation of facial fat distribution using magnetic resonance imaging

Magnetic resonance imaging (MRI) provides noninvasive images of facial and neck fat for a variety of conditions. It accurately maps the soft tissues pre- and postoperatively, enabling surgeons to precisely and objectively assess results of soft tissue facial contouring and fat transplantation. The risks of MRI are few. It has the potential to provide aesthetic surgeons with a more scientific means of comparing various techniques of fat contouring.
