The zygomaticomaxillary complex (ZMC) functions as a buttress for the face and is the cornerstone to a person's aesthetic appearance, by both setting the midfacial width and providing prominence to the cheek. Malar deficiency is often acquired by blunt injury incurred in a traumatic accident, resulting in ZMC fracture. A 48-year-old male patient presented a right ZMC fracture after contusion injury by a baseball. He only received conservative management and later he suffered discomfort during mouth opening at the moment of mastication, due to trismus involving the temporomandibular joint. In the current case, we describe a surgical technique, by which the malar body is shifted anteriorly and laterally after combined oblique-vertical osteotomy. The technique presented, eventually restored the former aesthetic position of the malar complex and symmetry, and, moreover, improved mastication function.

The complications of deep neck infection have become much less common in the antibiotic era. The vascular complications of deep neck infection can have devasting consequences. Most commonly, the internal carotid artery is involved, although the common carotid and external carotid artery can also be affected.0 the cases of patients with a protracted course, recurrent bleeding, cranial neuropathies, or trismus, the presence of vascular complications must be considered. Appropriate imaging should be carried out to allow the localization of the infection and ascertain the status of the vessels in the neck The vascular structures can be imaged with duplex doppler or color doppler flow ultrasound to see the flow between the mass and vessels. Also angiography plays a key role in the diagnosis and management of vascular complication of deep neck infection. Prompt diagnosis and treatment of these patients is necessary to prevent significant hemmorrhagic complications. We experienced a case of pseudoaneurysm of the common carotid artery secondary to deep neck infection treated successfully with surgical excision in 45-year-old-male.

Dexamethasone has been used in oral and maxillofacial surgery for postoperative pain, swelling, and trismus following third molar surgeries. It is a potent and powerful drug that can alleviate the aforementioned postoperative sequelae. Dexamethasone is responsible for inhibiting the release of inflammatory mediators in the inflammation process to improve patient quality of life after surgical intervention. There are several available routes of administering dexamethasone. This article will help determine the suggested routes of administration, dosage, parameters, and dexamethasone timing for third molar surgeries.

Temporomandibular disorders (TMD), involving the masticator system of temporomandibular joint (TMJ) and masticator muscle, can be characterized with the cardinal signs and symptoms of jaw pain, noises and limitation of mandibular range of motion. However, TMD requires differential diagnosis due to its heterogeneous characteristics with various causes despite the similar clinical profiles. Oral cancer involving TMJ and the masticator system, although infrequent, can be one of these causes and should be considered one of the most life-threatening disease mimicking TMDs. This report introduces a case of masticator space tumor originally diagnosed as TMD in a 73-year-old Korean female with previous history of brain tumor. The clinical signs and symptoms closely mimic that of TMD which may have disrupted differential diagnosis. We discuss here key points for suspecting TMDs of secondary origin, namely, that of cancer and the implications it has on dental clinicians.

Background: Third molar extraction is associated with considerable pain and discomfort, which is mostly managed with oral analgesic medication. We assessed the analgesic effect of benzydamine hydrochloride, a topical analgesic oral rinse, for controlling postoperative pain following third molar extraction. Methods: A randomized controlled trial was conducted in 40 patients divided into two groups, for extraction of fully erupted third molar. Groups A received benzydamine hydrochloride mouthwash and group B received normal saline gargle with oral ibuprofen and paracetamol. Oral ibuprofen and paracetamol was the rescue analgesic drug in group A. Patients were evaluated on the $3^{rd}$ and $7^{th}$ post-operative days (POD) for pain using the visual analogue score (VAS), trismus, total number of analgesics consumed, and satisfaction level of patients. Results: The VAS in groups A and B on POD3 and POD7 was $4.55{\pm}2.54$ and $3.95{\pm}1.8$, and $1.2{\pm}1.64$ and $0.95{\pm}1.14$, respectively and was statistically insignificant. The number of analgesics consumed in groups A and B on POD3 ($5.25{\pm}2.22$ and $6.05{\pm}2.43$) was not statistically different from that consumed on POD7 ($9.15{\pm}5.93$ and $10.65{\pm}6.46$). The p values for trismus on POD3 and POD7 were 0.609 and 0.490, respectively and those for patient satisfaction level on POD3 and POD7 were 0.283 and 0.217, respectively. Conclusions: Benzydamine hydrochloride oral rinses do not significantly reduce intake of oral analgesics and are inadequate for pain relief following mandibular third molar extraction.

Nasopharyngeal cancer is malignant tumor of nasopharyngeal area that is characterized of lymphadenopathy, pain, otitis media, hearing loss and cranial nerve palsy and may present symptoms similar to temporomandibular disorder such as facial pain and trismus. In this case, the patient with symptoms similar to temporomandibular disorder after surgery for otitis media presented with facial paresthesia and masticatory muscle weakness. Examinaion of trigemimal nerve was shown sensory and motor abnormaility. The patient was referred to a neurologist. Nasopharyngeal cancer was suspected on computed tomography and magnetic resonance imaging and was confirmed by biopsy. If the patient presenting with paresthesia and muscle weakness the cranial nerve examination should be performed regardless of typical temporomandibular disorder symptom. The neurologic symptom can be caused by neoplasm such as brain tumor and nasopharyngeal cancer. Nasopharyngeal cancer on rosenmuller fossa can develop otitis media. Therefore, the patient with otitis media history should be consulted to otorhinolaryngologist to examin the nasopharyngeal area.

The authors observed a patient who referred to the Department of Oral Radiology, due to diffuse skeletal pain, muscular weakness and unknown tumor mass on the buccal gingiva of upper right molar region. The patient was found to have peripheral reparative giant cell granuloma and osteomalacia. After removal of the tumor, the clinical, radiologic, and laboratory findings of the patient was rapidly normalized with remarkable improvement of bone pain. The results were as follows: 1. After removal of the tumor, the patient improved. the clinical findings such as bone pain, trismus. muscular weakness and he could walk. 2. In postoperative x-ray findings at 1 and 2 months intervals, the lamina dura of all dentition and bony trabeculae in upper and lower arches were regenerating and the bone density increased. 3. In periodic recall check, no occurrence of osteomalacia was existed and the laboratory findings of the patient showed gradual improvement.

Some complications can arise with the usage of local anesthesia for dental procedures, including the fracture of needles in the patient. This is a rare incident, usually caused by the patient's sudden movements during anesthetic block. Its complications are not common, but can include pain, trismus, inflammation in the region, difficulty in swallowing, and migration of the object, which is the least common but has the ability to cause more serious damage to the patient. This report describes a case in which, after the fracture of the anesthetic needle used during alveolar nerve block for exodontia of the left mandibular third molar, the fragment moved significantly in the first 2 months, before stabilizing after the third month of radiographic monitoring.
