We evaluated the need for prophylactic postoperative oral antibiotic medication in extraction of asymptomatic impacted mandibular third molars. All patient didn't show sign of pain, inflammation, swelling and trismus at the time of extraction. In the experimental group, oral antibiotic medication(Amoxicillin) was carried out for 5 days postoperatively. In the control group, the patients received no antibiotic medication. All groups didn't use antibiotic irrigation solution. Rule of group composition randomized. The surgical technique was the same in all cases. Parameters that were evaluated were infection, pain, facial swelling, trismus. We could not find any significant difference between the experimental and control groups.(P<0.05) The results of our study show that post operative oral prophylactic antibiotic medication after the extraction of impacted mandibular third molars does not contribute to less infection, pain, facial swelling and increased mouth opening after surgery. Therefore we suggest that prophylactic postoperative oral antibiotic medication is not needed in extraction of asymptomatic impacted mandibular third molars.

Background and Objectives The incidence of facial bone fracture is increasing. The zygomatic bone, due to its anatomical prominence, is the second most common site of all facial bone fractures. In this study, we present the clinical experiences of zygomatic arch fracture in a tertiary hospital and introduce the Gillies approach for reduction and its outcome results. Subjects and Method We collected data from retrospective chart reviews of patients who underwent surgeries from 2010 to 2017 for zygomatic arch fractures at Chungbuk National University Hospital. Data were analyzed according to age, gender, cause of trauma, location of trauma, and clinical symptoms including trismus. All surgery was performed under general anesthesia and via the use of Gillies approach. The result of surgery was evaluated by postoperative facial computed tomography. Results Sixteen patients underwent surgery for zygomatic arch fracture. The patients had the average age of 41.3 years, a male predominance of 15:1 and physical assault as the most common cause of trauma. The time lag between injury and surgical reduction was 5.5 days. The surgical outcomes were assessed 'good' in 14 cases and 'moderate' in one case. Patients who had trismus preoperatively were resolved of it in all cases after operation. Postoperative complications were absent. Conclusion The Gillies approach proved to be a relatively easy, safe, and reliable method, and its surgical outcomes was satisfactory in our experiences.

A 42-year old male patient was referred to the Department of Oral Medicine, Kyungpook National University Hospital due to the chief complaint of limite mouth opening. Three years ago, the patient was diagnosed as an infarction of both cerefellar hemispheres, acute obstructive hydrocephalus and acute epidural hematoma of frontal lobe at the department of neurosurgery.Both of the infarcted cerevellar hemispheres and the epidural hematoma of frontal lobe were removed with suboccipital and frontal craniectomu. After the brain surgery jaw opening range was decreased progressively and ultimately mouth opening became almost impossible. Spasmodic and rhythmic contractions of the masseter muscles occurred intermittently during daytime as well as sleeping. Food intake was available only through Levin -tube. Actibe jaw opening exercise was prescribed with the aids of tongue blades. A moist hot pack and indomethacin phonophesis were also applied 20 minutes three times a day to decrease discomfort muscle activities. After a month of treatments, the opening range was increased to 5mm at the premolar area and oral food intake was possibel. The L-tube was removed and the patient was discharged.

The tympanic plate is a small part of the temporal bone that separates the mandibular condyle from the external auditory canal. Fracture of this small plate is rare and usually associated with other bony fractures, mainly temporal and mandibular bone. There is a limited amount of literature on this subject, which increases the chance of cases being overlooked by physicians and radiologists. This is further supported by purely isolated cases of tympanic plate fracture without evidence of other bony fractures. Cone-beam computed tomography is an investigative three-dimensional imaging modality that can be used to detect fine structures and fractures in maxillofacial trauma. This article presents four cases of isolated tympanic plate fracture diagnosed by cone-beam computed tomography with no evidence of fracture involving other bones and review of the literature.

Congenital alveolar synechiae is a rare anomaly mostly presenting in association with cleft palate. Owing to reduced mouth opening, feeding difficulties, and compromised airway in extreme cases along with presentation in early neonatal period, these patients present unique challenges to the surgeon as well as the anesthetist. Here, we discuss the surgical and anesthetic management of this entity in a 12-month-old female child.

Bifid mandibular condyle (BMC) is an uncommon morphological variant of the mandibular condyle. Although authors have proposed various etiologies for BMC, no consensus has emerged. In addition, varying findings have been reported regarding the epidemiological parameters of BMC (e.g., prevalence, gender ratio, and age), possibly due to its low incidence. BMC is occasionally associated with symptoms of the temporomandibular joint, such as ankylosis, pain, and trismus; however, it is difficult to detect this condition on conventional radiographs. This study reports a case of BMC with radiographic findings, and reviews the literature on the epidemiology of BMC.

In this report, we describe a case of brain abscess due to odontogenic infection. A 53-year-old female who had been suffering from headache and trismus for two weeks visited the Department of Oral and Maxillofacial Surgery at the Sun Dental Hospital (Daejeon, Korea). Even after several routine tests, we still could not make a diagnosis. However, after the combined multidisciplinary efforts of oral surgeons and neurosurgeons, the patient was treated for odontogenic infection and made an uneventful recovery. Therefore, patients with infections in the head and neck region showing symptoms such as headache, changes in mental state, nausea, vomiting, seizures, hemiplegia, speech disturbance, and visual disturbance, a brain abscess should be included in the list of differential diagnoses.

Inferior alveolar nerve block obtained maximum anesthetic effect using a small dose of local anesthetic agent, which also has low a complication incidence. Complications of an inferior alveolar nerve block include direct nerve damage, bleeding, trismus, temporary facial nerve palsy, and etc. Among them, the major iatrogenic complication is dental needle fracture. A fragment that disappears into the soft tissue would be hard to remove, giving rise to a legal problem. A 31-year-old woman was referred for the removal of a broken needle, following an inferior alveolar nerve block. Management involved the removal of the needle under local anesthesia with pre- and peri-operative computed tomography scans.

Once a submasseteric space infection is diagnosed, the key to resolving the infection is via surgical intervention to evacuate the pus. Although it is possible and occasionally practical to drain the submasseteric space via an intraoral approach, an extraoral approach may sometimes be required. Surgeons have encountered complications such as facial nerve damage during extraoral incision and drainage procedures, and they have felt that extraoral dissection was very difficult. As such, an easier and simpler technique is needed. Our department recently modified various drainage techniques for submasseteric space abscesses. Damage to the marginal branch of the facial nerve did not occur, and this technique was very simple and rapid, such that a novice physician could perform this procedure. This modified technique was possible with trismus and under local anesthesia. After intraorally checking the position of the drain, the intraoral wound is closed with an absorbable suture and the drain is fixed to the extraoral skin. When a masseteric space infection is diagnosed, multiple space involvement is ruled out, and dependent drainage is required, this modified drainage technique can be useful.
