The management of victims of gunshot fractures is a challenge for surgeons, mainly due to the complexity of the injury itself and degree of bone comminution. The titanium functionally dynamic bridging plate has often been used in reconstructive surgery after mandibular fractures. The classic indication for bridge plate use is comminuted fractures with or without associated substance losses. The aim of this article is report the case of gunshot victim and to discuss the bridge plate technique utilized for treatment. A 21 years-old, melanoderma, male patient was victim of a firearm-related assault, with comminutive fracture of the mandibular body. The protocol for the bridging plate technique was performed. The patient is in postoperative follow-up of eight months, not present aesthetic or functional complaints, stable occlusion, satisfactory mouth opening and no clinical signs of infection.
Trauma is one of the leading causes of death worldwide. Due to its anatomy and position in the facial skeleton, the orbit becomes a region susceptible to trauma which may also involve the penetration of foreign bodies (FBs). These events can have serious repercussions depending on their extent due to the proximity of the orbit with other noble structures of the face and skull. Because of this, a system of prehospital management of traumas must be established, in order to promote a better prognosis for patients. The present study aims to report the case of a patient suffering from a motorcycle accident with multiple fragments of FBs in the region of orbit-zygomatic-maxillary complex. The emergency surgical removal of the fragments was performed by a multidisciplinary team, involving Ophthalmology and Oral and Maxillofacial Surgery and Traumatology (OMST). Wound cleansing and debridement were performed with subsequent removal of the foreign bodies by the OMST team, in addition to the reduction and fixation of related fractures. As for Ophthalmology, the evisceration of the affected eye was performed due to its anatomical and functional impairment. The patient is 12 months postoperatively, with no aesthetic or functional complaints regarding OMST. The anatomical knowledge of the traumatized region, besides the establishment of the conduct regarding the removal of possible associated foreign bodies are required so that the success of the treatment can be obtained, aiming to minimize the damages to the patient.
Orbital fractures are injuries frequently related to traumas of the midface. These fractures can be associated with ocular lesions, ranging from small abrasions on the cornea to serious complications such as hyphema and ocular globe rupture. Diplopia and ophthalmoplegia are common findings in orbital fractures. They can be caused by mechanical factors as bone fragments or muscle imprisonment. The aim of this study was to report a case of a 40-year patient, male showing diplopia and ophthalmoplegia due to the orbital fracture. The patient was treated by general anesthesia. It was performed a supra orbital approach and the fragments were removed. A titanium mesh to restore the orbital anatomy was installed. After 40 days of follow-up, the patient has no aesthetic or functional complaints. In orbital traumas, the ophthalmological evaluation should be performed carefully aiming to avoid ocular sequelaes. In surgical patients, the surgery should be done as early as the clinical conditions permit, to restore the ocular function.
Objective
The aim of this study is to compare the effect of photobiomodulation with low-level laser therapy (LLLT) and nimesulide on inflammatory parameters, biomarkers of oxidative stress and inflammation, and quality of life after lower third molar (L3M) surgery.
Material and methods
A randomized, two-factor, triple-blind, controlled, split-mouth clinical trial was performed with 40 volunteers who required bilateral L3M removal. Patients were allocated depending on the use or not of 100 mg nimesulide 1 hbefore surgery, as well as the use or not of LLLT in the preoperative period.
Results
Pain peaks occurred after 6 h (nimesulide-placebo [N-P] group) and 8 h (nimesulide group). In the N-P group, LLLT resulted in significantly lower mean pain scores than the subgroup without LLLT after 4 h (
p
= 0.009) and 6 h (
p
= 0.048). As for edema, a shorter distance between the mandibular angle and the outer canthus of the eyes after 7 days (
p
= 0.037) and a smaller cumulative effect (
p
= 0.036) were observed in the N-P group associated with LLLT. A direct effect between LLLT (
p
= 0.047) and a reduction in the mean scores of overall dissatisfaction with quality of life was detected.
Conclusions
Preemptive use of nimesulide only delayed peak pain. LLLT reduced edema, trismus, and contributed to a better perception of quality of life. Nimesulide inhibits peroxidation by increasing GSH and stopping neutrophil migration. The benefit of the association of both strategies was not superior to the use of LLLT alone.
Clinical relevance
Translational study with impact on clinical-surgical protocols involving L3M surgery related to pharmacological and non-pharmacological methods.
Pleomorphic adenoma (PA) is the most common benign salivary gland neoplasm, and its malignant transformation rarely occurs. Diagnosis is based on clinical features of local or regional malignancy or distant metastasis, and histological identification of invasion and cellular atypia. Buccal fat pad, also called Bichat fat pad, is an excellent option to create tissue coverage over surgically treated areas, providing great blood supply. Thus, this study aims to report a surgical treatment of a patient who reported to the Oral and Maxillofacial Surgery and Traumatology service of a hospital in the city of Fortaleza, presenting a large lesion in the right side of the palate. Clinical examination revealed a nodular volume increase with smooth surface, sessile insertion, firm to palpation and coloration similar to the mucosa, no pain complaints, and 2 years of evolution. Orthopantomographic examination did not reveal alterations in the adjacent anatomical structures. After clinical and radiographic evaluation, an incisional biopsy was performed and histopathological diagnosis was PA. Patient was submitted to surgery for tumor excision with narrow surgical margins, including oral lining mucosa to reduce recurrence chances. In the same surgical act, after the excision of the lesion, the right buccal fat pad pedicle flap was sutured onto the residual mucosa in order to act as a framework for re-epithelialization of the palatal mucosa, phenomenon of metaplasia, and reduction of patient's morbidity. Surgical piece obtained was sent to anatomopathological study, confirming initial diagnosis. After 12-month follow-up, patient is esthetically and functionally rehabilitated, and satisfied with clinical and surgical plans executed.
