Local Administration of ElectroMagnetic Field as Add-On Therapy in the Treatment of Chronic Facial Pain: A Pilot Study
No full text: Fibromyalgic syndrome and orofacial neuropathic pain are major public health concerns affecting up to 5% and 10%, respectively, of the general population. They generally require medications such as antidepressants and anticonvulsants, which may additionally impact the quality of life with their side effects. Modern technologies and related applications have changed several fields of human life, even in medicine. In the current study, the local administration of electromagnetic fields as add-on therapy for the treatment of cervical and facial pain in patients with fibromyalgia or neuropathic pain has been evaluated. A total of 15 patients were recruited, and an electromagnetic field was delivered through a small patch applied between C3 and C4. Patients were followed for 12 months, and pain levels were rated via the VAS scale; ∆% was calculated through the analysis of median VAS scale values at each time point. Mild-to-moderate improvements were found, especially after six months. Patients with fibromyalgic syndrome showed better response rates than those with orofacial neuropathic pain. Joint stiffness, masticatory fatigue, and sleep disturbances were also reduced. In conclusion, the local application of electromagnetic field appeared effective in treating fibromyalgic and neuropathic pain in the head and neck district, with broader improvements and no side effects
Femoral nerve palsy after mandibular reconstruction with microvascular iliac flap: a complication under anticoagulation therapy
No full textPharmacological prophylaxis and intervention are used extensively in head and neck reconstructions with microvascular flaps. There is no universally accepted protocol, but the microvascular surgery literature recommends intraoperative anticoagulation with heparin. Here is reported a case of iliacus haematoma with subsequent femoral nerve palsy after the harvest of a microvascular iliac nap for mandibular reconstruction in a patient who had been treated with heparin. The association between femoral nerve palsy and anticoagulant therapy has been well described. It remains unclear as to why the iliacus muscle is particularly vulnerable to intramuscular haemorrhage. Femoral nerve neuropathy is also an uncommon but recognized complication after abdominopelvic surgery. Iliacus haematoma secondary to microvascular surgery has not been previously reported. This case illustrates the need to be aware of this type of complication and its clinical manifestations for patients under anticoagulant therapy in the perioperative period during microvascular reconstructions
Bone biological plate for stabilization of maxillary inferior repositioning
No full textAim: Inferior repositioning of the maxilla to correct vertical maxillary deficiency has been one of the more unstable orthognathic procedures performed. Different surgical techniques have been proposed to stabilize downward movement of the maxilla. The aim of this study was to evaluate the skeletal stability of maxillary anterior downgrafting using bone biological plates in association to bone plates and bone graft for skeletal stabilization. Methods: The records of 6 patients were evaluated cephalometrically, analyzing the presurgical, immediate postsurgical and long-term follow-up radiographs. All patients had one-piece Le Fort I osteotomy with anterior downgraft of at least 2 mm at point A. Any horizontal movement of the maxilla concomitant with the downgraft was no more than 5 mm. Rigid fixation with titanium miniplates and screws and with bone biological plate was used to stabilize the maxilla. In the sample of 6 patients, 3 underwent one-jaw (maxilla only) surgery and 3 two-jaw surgery. Results: The mean surgical inferior downgrafting at point A was 5+/-1.4 mm (P<0.001) with a relapse of 0.16+/-1. 63 mm (3.2% of surgical movement). The mean surgical inferior downgrafting at the anterior nasal spine (ANS) was 5.66+/-1.36 mm (P<0.001) with a relapse of 0.41+/-1.56 mm (7.32% of surgical movement). Relapse in the vertical dimension failed to reach any statistical significance for all maxillary landmarks. Conclusions: Anterior downgrafting of the maxilla with this fixation method seems to be a stable and predictable procedure. The use of bone biological plates seems to substantially improve skeletal stability even if further investigations with a more consistent sample of patients is required
Myoepithelioma of the parotid gland: Case report and review of literature
No full textSummaryThe present paper describes the clinical and pathologic features of a benign myoepithelioma of the parotid gland. Through 1985, only 42 other cases had been reported in the literature: three malignant and 39 benign. Fewer than 100 cases had been reported through 1993. The number of case reports of myoepitheliomas is increasing as pathologists have become more aware of their existence. This uncommon tumor is most commonly diagnosed in the parotid gland and in the minor salivary glands of the palate. The complex and varied morphologic expression of neoplastic myoepithelium have attracted numerous investigators who have presented valuable but often contradictory data. It is our opinion that these tumors are not as rare as is generally believed, but they are simply not well recognized. Together with a review of the literature, consideration are presented on the clinical evaluation, differential diagnosis and treatment of these lesions
Resorbable plates in maxillary fixation. A 5-year experience
No full textAim: Metallic plates and screws have become the routine way of stabilizing the facial skeleton; however, there are many disadvantages in the use of metallic devices. Fixation systems made of biocompatible absorbable material, with appropriate load-bearing properties and sufficient degradation rate can overcome these disadvantages. Recently, resorbable materials were tested in maxillary, mandibular and chin osteotomies. Despite a lot of reports on the use of resorbable bone fixation devices in cranio-maxillo-facial application are now available, their use in preprosthetic surgery has yet to be adequately documented. The Authors report their 5-year experience in the employment of resorbable fixation in surgery of the superior maxilla, involving orthognathic and preprosthetic procedures of the upper jaws. The surgical technique is described and usefulness and advantages are discussed. Methods: Plates and screws were composed of an 82% poly-L-lactic acid/18% polyglycolic acid copolymer (PLLA-PGA); 50 orthognathic and 5 preprosthetic procedures of upper jaws were involved, performing Le Fort I osteotomies in all cases. Results: Our operations were were carried out without complications. Follow-up ranged from 6 months to 5 years. One patient developed a localized buccal space infection which resolved after a course of antibiotics given orally. Conclusions: Resorbable fixation should be considered adequate for fixation in maxillary surgery
Chronic Facial Pain in Fibromyalgia: May ElectroMagnetic Field Represent a Promising New Therapy? A Pilot Randomized-Controlled Study
No full textFibromyalgic Syndrome is an important public health burden and affects up to 5% of the world population. It requires a complex treatment plan, possibly including antidepressants, anticonvulsants and benzodiazepines, which may in turn affect the patients’ quality of life: hence the need to find additional therapies. The current pilot randomized-controlled study analyzes the effect of electromagnetic field locally administered as add-on therapy in the treatment of cervico-facial pain in patients with fibromyalgic syndrome. 17 patients were selected and low-frequency electromagnetic field was applied via small patches worn in the neck area, between vertebrae C3–C4. Patients were divided into 2 groups, Treated, receiving the therapy, and Placebo, receiving an identical device which was not working,, with respectively 8 and 9 patients. The whole follow up period was 12 months and facial/cervical pain levels were rated using VAS scale. Significant differences were found between patients who received placebo and those treated. Treated patients showed statistically significant improvements in facial/cervical pain at each time-point, both with respect to the previous one and if compared to placebo. In conclusion, low frequency electromagnetic field emerged as beneficial in treating cervico-facial pain in patients with Fibromyalgic syndrome, with no side effects
Ultrasonic bone cutting for surgically assisted rapid maxillary expansion (SARME) under local anaesthesia
No full textUltrasonic bone-cutting surgery has been recently introduced as a feasible alternative to the conventional tools of cranio-maxillo-facial surgery, due to its technical characteristics of precision and safety. The device used is unique in that the cutting action occurs when the tool is employed on mineralized tissues, but stops on soft tissues. This technical note illustrates the use of Piezosurgery(R) for all osteotomies of surgically assisted rapid maxillary expansion (SARME). The procedure, including pterygo-maxillary detachment, can be completed under local anaesthesia. Other advantages include minimal risk of jeopardizing critical anatomic structures (e.g. palatine artery), minimal intraoperative bleeding and postoperative swelling, and minimal thermal damage to bone surfaces. Narrow and rectilinear osteotomies can be easily performed with varying vibrating scalpels, at the cost of a longer operative time
Ultrasound bone cutting for surgically assisted rapid maxillary expansion under local anesthesia. Preliminary results
No full text: Surgically assisted rapid maxillary expansion (SARME) is a well-established therapy for correction of maxillary transverse deficiency in adults, when consolidation of sutures has just been completed. It can be performed either under general or under local anesthesia and it can be accomplished with many surgical techniques. One of the most critical steps of SARME is the detachment of the pterygo-maxillary junction, due to the risks connected to such procedure. When required to obtain specific expansion patterns, the pterygo-maxillary separation has been suggested until now only for interventions under general anesthesia, due to the dangerousness and the rawness of this surgical step in awake patients. The authors introduce the use of an ultrasonic bone-cutting device to perform all osteotomic steps of SARME under local anesthesia on an outpatient basis, including pterygo-maxillary detachment. This ultrasonic device is unique in that the osteotomic action occurs only when the tool is employed on mineralized tissues, while it stops on soft tissues. It works in a linear pattern of vibration and it allows precise osteotomies without producing any heat damage to osteotomic surfaces and without any dangerous hammer-related stroke. Due to its precision and safety, this device named Piezosurgery, allows patients to undergo all the steps of SARME under local anesthesia, also without hospitalization
Root fractures in the primary teeth and their management: a scoping review
No full textBackground: Traumatic dental injuries constitute a major global health problem. Primary deciduous teeth of the upper frontal group are frequently affected by trauma, especially at an early age. It is important to treat primary traumatic injuries because early tooth loss can lead to aesthetic and functional alterations. The most common injuries are extrusion, lateral luxation, and intrusion. Root fracture is a less common complication that can lead to tooth extraction if not properly diagnosed and managed. However, there are a lack of data regarding primary root fracture treatment. The literature was reviewed to study the current knowledge on the treatment of these injuries, and to propose an operative protocol based on the results obtained. (2) Methods: A literature search was performed on Web of Science, PubMed/MEDLINE, and SCOPUS. The research focused on the following features: age of the patient; localization of the root fracture and type of displacement suffered (intrusive, extrusive, or lateral); type of emergency treatment or diagnostic test performed and their compliance with IADT guidelines; follow-up duration. (2) Results: Only 8 articles fully met the inclusion criteria, with a total of 46 patients and 62 root fractures. Out of a total of 62 root fractures, regarding only upper incisors, the most common treatment was splinting (n = 39) for a period ranging from 3 weeks to 3 months (with an average of six weeks). No treatment was performed for 23 of the root fractures. The splinting performed in most of the included cases was semi-rigid, with the splint held in place using a composite resin material. An orthodontic splint using brackets and 0.5 mm stainless steel wire was used in only in one study. (4) Conclusions: We deduced that the root fracture of primary teeth is a rare traumatic dental injury that can cause numerous complications, such as eruptive problems in the permanent teeth. Correct radiological diagnosis, immediate repositioning and semi-rigid splinting could be conservative methods to prevent premature tooth loss in very young patients
