1/22. Orofacial pain emerging as a dental specialty.The emerging field of orofacial pain was considered by the american dental association for full status as a new dental specialty. While the recognition of orofacial pain as a specialty was denied, the American Academy of Orofacial Pain plans to continue its efforts. Many recent advances in the neuroscience of orofacial pain have led to treatments that provide significant relief for patients with chronic orofacial pain disorders. However, access to this care has been limited, leaving many patients to suffer. dentists are generally supportive of the efforts to develop oral pain treatment into a specialty because the field will provide benefits for both dentists and their patients. A recent survey of 805 individuals who reported having a persistent pain disorder revealed that more than four out of 10 people have yet to find adequate relief, saying their pain is out of control--despite having the pain for more than five years and switching doctors at least once. "This survey suggests that there are millions of people living with severe uncontrolled pain," says Russell Portenoy, MD, president of the American Pain Society. "This is a great tragedy. Although not everyone can be helped, it is likely that most of these patients could benefit if provided with state-of-the-art therapies and improved access to pain specialists when needed." Development of the field of orofacial pain into a dental specialty has been moved primarily by the fact that historically, patients with complex chronic orofacial pain disorders have not been treated well by any discipline of healthcare. Recent studies of chronic orofacial pain patients have found that these patients have a higher number of previous clinicians and have endured many years with pain prior to seeing an orofacial pain dentist (see Figure 1). Complex pain patients and the clinicians who see them are often confused about who they should consult for relief of the pain. Treatment for those patients within the existing structure of dental or medical specialties has been inadequate, with millions of patients left suffering. Insurers are also confused with regard to reimbursement and may make decisions to exclude treatment for orofacial pain disorders under both dental and medical policies. However, dentistry has taken a leading role in healthcare to address the national problem of developing the field of orofacial pain into a dental specialty. A study of dentists and dental specialists has shown that there is a recognized need and broad support for developing this field into a specialty.- - - - - - - - - - ranking = 1keywords = suffering (Clic here for more details about this article) |
2/22. Neuropathic orofacial pain. Part 2-Diagnostic procedures, treatment guidelines and case reports.Neuropathic orofacial pain can be difficult to diagnose because of the lack of clinical and radiographic abnormalities. Further difficulties arise if the patient exhibits significant distress and is a poor historian regarding previous diagnostic tests and treatments, such as somatosensory local anaesthetic blockade. Valuable information can be obtained by utilising the McGill Pain Questionnaire that allows the patient to choose words that describe the qualities of his/her pain in a number of important dimensions (sensory and effective). Basal pain intensity should be measured with the visual analogue scale, a simple instrument that can evaluate the efficacy of subsequent treatments. The dentist or endodontist can employ sequential analgesic blockade with topical anaesthetics and perineural administration of plain local anaesthetic to ascertain sites of neuropathology in the PNS. These can be performed in the dental chair and in a patient blinded manner. Other, more specific, tests necessitate referral to a specialist anaesthetist at a multidisciplinary pain clinic. These tests include placebo controlled lignocaine infusions for assessing neuropathic pain, and placebo controlled phentolamine infusions for sympathetically maintained pain. The treatment/management of neuropathic pain is multidisciplinary. Medication rationalisation utilises first-line antineuropathic drugs including tricyclic antidepressants such as amitriptyline and nortriptyline, and possibly an anticonvulsant such as carbamazepine, sodium valproate, or gabapentin if there are sharp, shooting qualities to the pain. mexiletine, an antiarrhythmic agent and lignocaine analogue, may be considered following a positive patient response to a lignocaine infusion. All drugs need to be titrated to achieve maximum therapeutic effect and minimum side effects. Topical applications of capsaicin to the gingivae and oral mucosa are a simple and effective treatment in two out of three patients suffering from neuropathic orofacial pain. Temporomandibular disorder is present in two thirds of patients and should be assessed and treated with physiotherapy and where appropriate, occlusal splint therapy. attention to the patient's psychological status is crucial and requires the skill of a clinical psychologist and/or psychiatrist with pain clinic experience. Psychological variables include distress, depression, expectations of treatment, motivation to improve, and background environmental factors. Unnecessary dental treatment to "remove the pain" with dental extractions is contraindicated and aggravates neuropathic orofacial pain.- - - - - - - - - - ranking = 1keywords = suffering (Clic here for more details about this article) |
3/22. Orofacial pain as the sole manifestation of syringobulbia-syringomyelia associated with arnold-chiari malformation.This is a case report of a male patient who presented with orofacial pain for a year as the only manifestation of syringobulbia-syringomyelia associated with arnold-chiari malformation. This article places emphasis on the clinical presentation and possible differential diagnoses. The pain was continuous and affected the left side of the face. It was exacerbated by coughing and physical effort, possibly as a consequence of an increase in intracranial pressure. Paroxysmal pain crises developed over this background of continuous pain, compatible with neurogenic trigeminal pain of the left second branch, together with pain episodes similar to cluster headache on the same side. The symptoms were resolved following neurosurgical management with amplification of the foramen magnum.- - - - - - - - - - ranking = 0.92355165235121keywords = physical (Clic here for more details about this article) |
4/22. A review of intractable facial pain secondary to underlying lung neoplasms.We describe a 63-year-old smoker who suffered from intractable facial pain secondary to an underlying lung neoplasm. Data from 30 previously reported and similar cases are also summarized. The clinical triad of a smoker suffering from periauricular pain and an elevated ESR should alert the clinician to the possibility of an occult lung mass. In these cases a computed tomography of the chest should always be obtained. Previously refractory pain typically responds to surgical resection of the mass and/or radiation therapy.- - - - - - - - - - ranking = 1keywords = suffering (Clic here for more details about this article) |
5/22. Oral and maxillofacial surgery in patients with chronic orofacial pain.PURPOSE: In this investigation, we evaluated a population of patients with chronic orofacial pain who sought treatment at a pain center in an academic institution. These patients were evaluated with respect to 1) the frequency and types of previous oral and maxillofacial surgery procedures, 2) the frequency of previous significant misdiagnoses, and 3) the number of patients who subsequently required surgical treatment as recommended by an interdisciplinary orofacial pain team. The major goal of this investigation was to determine the role of oral and maxillofacial surgery in patients with chronic orofacial pain. patients and methods: The study population included patients seen at the Center for Oral, Facial and Head Pain at new york Presbyterian Hospital from January 1999 through April 2001. (120 patients; female-to-male ratio, 3:1; mean age, 49 years; average pain duration, 81 months; average number of previous specialists, 6). The patient population was evaluated by an interdisciplinary orofacial pain team and the following characteristics of this population were profiled: 1) the frequency and types of previous surgical procedures, 2) diagnoses, 3) the frequency of previous misdiagnoses, and 4) treatment recommendations made by the center team. RESULTS: There was a history of previous oral and maxillofacial surgical procedures in 38 of 120 patients (32%). Procedures performed before our evaluation included endodontics (30%), extractions (27%), apicoectomies (12%), temporomandibular joint (TMJ) surgery (6%), neurolysis (5%), orthognathic surgery (3%), and debridement of bone cavities (2%). Surgical intervention clearly exacerbated pain in 21 of 38 patients (55%) who had undergone surgery. Diagnoses included myofascial pain (50%), atypical facial neuralgia (40%), depression (30%), TMJ synovitis (14%), TMJ osteoarthritis (12%), trigeminal neuralgia (10%), and TMJ fibrosis (2%). Treatment recommendations included medications (91%), physical therapy (36%), psychiatric management (30%), trigger injections (15%), oral appliances (13%), biofeedback (13%), acupuncture (8%), surgery (4%), and Botox injections (1%) (Allergan Inc, Irvine, CA). Gross misdiagnosis leading to serious sequelae, with delay of necessary treatment, occurred in 6 of 120 patients (5%). CONCLUSIONS: Misdiagnosis and multiple failed treatments were common in these patients with chronic orofacial pain. These patients often have multiple diagnoses, requiring management by multiple disciplines. Surgery, when indicated, must be based on a specific diagnosis that is amenable to surgical therapy. However, surgical treatment was rarely indicated as a treatment for pain relief in these patients with chronic orofacial pain, and it exacerbated and perpetuated pain symptoms in some of them.- - - - - - - - - - ranking = 0.92355165235121keywords = physical (Clic here for more details about this article) |
6/22. Cemento-ossifying fibroma of the ethmoidal sinus in a child presenting with isolated pain in the nasal region.The authors present a case of a previously healthy 8-year-old girl who presented with pain on the right side of the nose (bony part) radiating to the frontal and temporal regions. physical examination was normal, whereas magnetic resonance imaging (MRI) of the facial region revealed a tumor limited to the right ethmoidal sinus with a small extension to the medial wall and the upper part of the nasal septum. The tumor was removed by using a 5-degree nasoscope and sent for pathologic examination, which revealed a cemento-ossifying fibroma of the ethmoidal sinus. This is a rare condition, and MRI is a valuable tool in its detection because results of physical examination may be normal in patients reporting nasal pain. According to the world health organization classification, this tumor is a variant of cementifying fibromas, which represent a subgroup of cementomas, fibro-osseous lesions containing cementum. Cementifying fibromas are rare tumors. They are usually small, asymptomatic lesions, but although benign, they can develop into aggressive, expansible masses.- - - - - - - - - - ranking = 0.92355165235121keywords = physical (Clic here for more details about this article) |
7/22. facial pain.facial pain is a common symptom that may be a feature of a primary headache disorder or a secondary feature of organic disease. A thorough clinical history and physical examination may reveal the characteristic clinical features and assist in diagnosis. However, in some cases, the etiology may remain indeterminate.- - - - - - - - - - ranking = 0.92355165235121keywords = physical (Clic here for more details about this article) |
8/22. Heterogeneity in the clinical presentation of Eagle's syndrome.OBJECTIVE: Eagle's syndrome (ES) or symptomatic elongated styloid process is an uncommon but important cause of chronic head and neck pain. This study reports our experience in the diagnosis and treatment of a series of patients with ES. STUDY DESIGN: Patient histories, radiographic tests, and operative reports of 3 patients over a 3-month period were prospectively collected. SETTING: Tertiary referral otolaryngology service. RESULTS: All patients had resolution of symptoms relating to their elongated styloid processes after surgical resection. CONCLUSION: Although sometimes clouded by coexisting symptoms, ES can be easily diagnosed based on good history taking and physical examination. If diagnosed appropriately, surgical treatment can be administered promptly. SIGNIFICANCE: patients with ES commonly have a long history of chronic pain treated by multiple physicians. Appropriate diagnosis can lead to prompt treatment of this condition.

9/22. Proposal for a standardized protocol for the systematic orofacial examination of patients with Hereditary Sensory Radicular Neuropathy.AIM: To apply a standardized protocol for the orofacial evaluation of two adult siblings (one male and one female) with Hereditary Sensory Radicular Neuropathy (HSRN) that presented with dental problems. SUMMARY: The systematic evaluation consisted of (a) clinical questionnaire; (b) radiographs [orthopantomography and computarized tomography (CT)]; (c) orofacial psychophysical tests (pain, thermal, mechanical and electrical sensation); and (d) histology of gingiva and pulp (optical and transmission electronic microscopy). The female patient had complete insensitivity to orofacial pain and partial facial heat sensitivity, and received dental treatment without anaesthesia or pain. She had a severe and painless jaw infection due to pulp necrosis in tooth 37. The male patient had partial insensitivity to orofacial pain and required anaesthesia for dental treatment. Histological examination of gingivae and pulpal tissue revealed an altered proportion of unmyelinated and myelinated sensory nerve fibres. KEY learning POINTS: * patients with HSRN may present with significant, silent dental disease. * A standard protocol is helpful when evaluating such patients. * If the opportunity arises, evaluation of pulp tissue may reveal an altered proportion of myelinated and unmyelinated nerve fibres. This may avoid the more estabilished sural nerve biopsy.- - - - - - - - - - ranking = 0.92355165235121keywords = physical (Clic here for more details about this article) |
10/22. Infratemporal space pathosis mimicking TMJ disorders.The differential diagnosis of pain in the face and dysfunction of the masticatory system is complex. Although most diagnoses are readily made, common symptoms can occasionally belie more serious diseases. Each patient was originally treated for TMJ dysfunctions and subsequently was diagnosed as suffering from pathosis of the infratemporal space.- - - - - - - - - - ranking = 1keywords = suffering (Clic here for more details about this article) |
