BACKGROUND: The goal of the treatment of direct carotid cavernous fistula (CCF) is to occlude the arteriovenous shunt and to preserve the patency of the concerned internal carotid artery (ICA). However, for the ipsilateral post-traumatic fragile cerebrum, coil embolization plus parent artery occlusion for the high flow direct CCF would be better for the prevention of hyper-perfusion syndrome and the intracranial hemorrhage. We experienced such a case and managed it successfully. CASE DESCRIPTION: A 6-year-old boy was suffered from severe head trauma caused by being hit by a car...

Facial synkinesis is the simultaneous contraction of the certain facial musculature accompanying a motion of designated muscle in the face. With the exception of rare afflictions that are congenital in origin, most patients develop as a sequel to facial nerve paralysis due to trauma, tumor, and surgical injury. As an idiopathic congenital form, oculo-nasal synkinesis which reveals co-contraction of orbicularis oculi and the compressor narium minor muscles which are innervated by separate branches of the facial nerve have been already reported...

INTRODUCTION: Anatomical reduction of displaced acetabular fracture is not without its' limitations and complications. This study is conducted to assess clinical and radiological outcomes as well as complications of treating displaced acetabular fractures with emphasis on anatomical reduction in weight-bearing area, mainly the posterior column, and imperfect reduction of the anterior column is acceptable. However, stability of both columns is mandatory. METHODS: It was a retrospective study carried out in a Level 1 arthroplasty and trauma centre...

The aim of this retrospective study was to investigate the frequency of persistent ulnar affection in patients who underwent open reduction and internal fixation (ORIF) of distal humeral fractures without ulnar nerve transposition or mobilisation. Eighty-two patients (53 women), mean age 62 years, were, at a mean of 48 months, reviewed through medical records and a subjective evaluation form concerning ulnar nerve problems. Ulnar nerve affliction, in most cases regarded as mild, was experienced by 22 patients (27%; 14 women) and significantly associated with multiple surgeries...

A 52-year-old man was injured when driving through the gate by a motorcycle without noticing the rope between the gateposts. He developed hoarseness, subcutaneous emphysema and dyspnea, and was transferred to our hospital by an ambulance. Chest X-ray and computed tomography showed subcutaneous and mediastinal emphysema, and complete transection of the cervical trachea. Since respiratory distress progressed rapidly, we performed tracheostomy in the intensive care unit, and the patient was carried to the operating room...

INTRODUCTION: Open chest surgery (thoracotomy) is considered the most painful of surgical procedures. Forceful wound retraction, costochondral dislocation, posterior costovertebral ligament disruption, intercostal nerve trauma and wound movement during respiration combine to produce an acute, severe postoperative pain insult and persistent chronic pain many months after surgery is common. Three recent systematic reviews conclude that unilateral continuous paravertebral blockade (PVB) provides analgesia at least equivalent to thoracic epidural blockade (TEB) in the postoperative period, has a lower failure rate, and symptom relief that lasted months...

BACKGROUND: The differential diagnosis of facial anesthesia is vast. This may be secondary to trauma, neoplasm, both intracranial and extracranial, infection, and neurologic disease. When evaluating a patient with isolated facial anesthesia, the head and neck surgeon often thinks of adenoid cystic carcinoma, which has a propensity for perineural invasion and spread. When one thinks of head and neck squamous cell carcinoma with or without unknown primary, the typical presentation involves dysphagia, odynophagia, weight loss, hoarseness, or more commonly, a neck mass...

Neuropathic pain is triggered by the lesions to peripheral nerves which alter their structure and function. Neuroprotective approaches that limit the pathological changes and improve the behavioral outcome have been well explained in different experimental models of neuropathy but translation of such strategies to clinics has been disappointing. Experimental evidences revealed the role of free radicals, especially peroxynitrite after the nerve injury. They provoke oxidative DNA damage and consequent over-activation of the poly(ADP-ribose) polymerase (PARP) upregulates pro-inflammatory pathways, causing bioenergetic crisis and neuronal death...

Tail docking of pigs is commonly performed to reduce the incidence of unwanted tail-biting behaviour. Two docking methods are commonly used: blunt trauma cutting (i.e. using side clippers), or cutting and concurrent cauterisation using a hot cautery iron. A potential consequence of tail amputation is the development of neuromas at the docking site. Neuromas have been linked to neuropathic pain, which can influence the longer-term welfare of affected individuals. To determine whether method of tail docking influences the extent of neuroma formation, 75 pigs were allocated to one of three treatments at birth: tail docked using clippers; tail docked using cautery iron; tail left intact...

BACKGROUND: Repair of distal biceps tendon ruptures has become widely accepted. Unfortunately, care of retracted-degenerated injuries remains a challenge for orthopedic surgeons. Complication rates appear to increase when surgery is performed in chronic cases compared to those operated acutely. Multiple techniques for chronic reconstruction with the use of grafts have been described. Recently Morrey, from the Mayo Clinic, proposed a direct anatomic repair of retracted distal biceps tendon ruptures in extreme flexion (60°-90°) to avoid grafting...

PURPOSE: The purpose of our study was to investigate whether the occurrence of preoperative diplopia determines the incidence of postoperative diplopia after orbital floor repair. MATERIALS AND METHODS: We undertook a retrospective cohort study with a review of the records of 126 consecutive patients who had undergone repair of an orbital floor fracture under the maxillofacial surgery service at John Hunter Hospital (Newcastle, NSW, Australia). The primary predictor variables were a number of demographic, etiologic, and operative factors that might influence the occurrence of diplopia...

OBJECTIVE: This study was conducted to investigate subclinical electrophysiological deleterious effect due to microtrauma to the nerve in response to the dissection of a tumor and parotid tissue from the facial nerve and its branches and surgical traction experienced during the operation. METHODS: The study included 34 adult patients who underwent parotidectomy operations under intraoperative facial nerve monitoring. Three measurements were taken from each patient to evaluate facial nerve functions, with 3 stimuli of different intensities applied with different timing...

Importance: Among cranial nerve palsies, a third nerve palsy is important because a subset is caused by life-threatening aneurysms. However, there is significant disagreement regarding its incidence and the reported etiologies. Objective: To determine the incidence and etiologies of acquired third nerve palsy using a population-based method. Design, Setting, and Participants: All newly diagnosed cases of acquired third nerve palsy from January 1, 1978, through December 31, 2014, in Olmsted County, Minnesota, were identified using the Rochester Epidemiology Project, a record-linkage system of medical records for all patient-physician encounters among Olmsted County residents...

As classically described, Eagle syndrome is an entity where patients develop pain or neurologic manifestations arising from an elongated styloid process and/or an ossified stylohyoid ligament irritating or compressing adjacent cranial nerves or the carotid arteries. Over the past few years, there have been reports of actual injury to the internal carotid artery with dissection, occlusion and strokes. We present three cases identified after blunt trauma-one due to carotid compression and two due to actual injury to the internal carotid artery...

BACKGROUND: Early development and eruption of permanent teeth are rarely reported in scientific literature. Early eruption of permanent teeth has been reported to occur due to local factors such as trauma or dental abscesses in primary teeth, and in systemic conditions. Congenital diffuse infiltrating facial lipomatosis (CDIFL) is a rare condition that belongs to a group of lipomatosis tumours. In this disorder, the mature adipocytes invade adjacent soft and hard tissues in the facial region...

Sensory and motor neuropathy of the trigeminal nerve due to trauma is quite rare. Furthermore, there have been no detailed reports on occlusal abnormalities and trismus associated with post-traumatic trigeminal motor neuropathy. Here, the authors report a case of trigeminal motor neuropathy and trigeminal sensory neuropathy in all 3 divisions caused by an orbital stab wound. During kendo practice, a 61-year-old man was injured in his right medial canthus with the splinter of a broken bamboo sword. Imaging examinations did not show a brain injury or orbital bone fracture...

REVIEW

Perineural catheter infection is a rare but potentially dramatic complication of continuous peripheral nerve block. Different risk factors have been identified and the incidence of infection is increased in trauma victims, intensive care unit patients, immunodeficient individuals, and diabetic patients. Also, postoperative hyperglycemia, the absence of antibiotic prophylaxis, and catheter lasting more than 48 hours seem to be associated with a greater risk of infection. Skin disinfection and a strict aseptic technique during catheter placement are fundamental...
