The dentigerous cyst originates through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium or between this epithelium and the tooth crown. It is always associated with unerupted teeth. There are two methods of treament which are generally accepted. One is the enucleation of the cystic sac in its entirety, the other is the Partch operation, or the marsupialization, by which the cyst is uncovered or "deroofed" and the cystic lining made continuous with the oral avity or surrounding structures. The present case report showed that in instance of dentigerous cyst & odontogenic keratocyst surgical enucleation followed by careful excision of all cyst wall was successfully carried out and recovery and healing were rapid and uncomplicated.

Actinomycosis is an unusual granulomatous infection caused by gram-positive anaerobic bacteria called Actinomyces species(predominantly Actinomyces israelii), which is a common and normally nonpathogenic organism found in the nose and throat. The three major clinical presentations of actinomycosis include the cervico-facial(the most common, 55%), thoracic, and abdominopelvic region. Actinomycosis typically has a chronic, indolent course characterized by swelling and induration of the soft tissues and eventual spontaneous drainage through multiple sinus tracts. Actinomycosis is difficult to diagnose because of variable presentation mimicking neoplasm and fastidious nature of the organism in culture. We present a case of actinomycosis in the parotid tip area which was mistaken for a salivary tumor.

This is an extermely rare disease and a case of tuberculous osteomyelitis of mandible in a 45-year-old woman was reported. The patient was visited for complaining slight facial swelling on left side and purulent discharge from extracted socket. Roentgenograhic examination of the mandible revealed bone destruction on left side of mandibular body. Destructive lesion was removed with saucerization and specimen from the involved soft tissue and bone were sent for microscopic examination. This case proved to be primary tuberculous osteomyelitis caused by the absence of primary focus. After 3 months follow-up check, we noticed good prognosis of bone and soft tissue healing.

Fibrous dysplasia is a benign fibro-osseous condition that is replacement of normal bone and marrow tissues by cellular fibrous tissue and immature bone, and it is divided into monostotic type and polyostotic type. Polyostotic fibrous dysplasia involves multiple bones, such as skull, jaw bones, femur and tibia. And it is also divided into two forms: the less severe Jaffe's type and the more severe Albright's syndrome. Clinically, it frequently occurs in the 2nd decade, and occurs more frequently in maxilla than in mandible. And the lesions of fibrous dysplasia tend to become static as skeletal maturity is reached. The authors experienced three cases of polyostosic fibrous dysplasia in the craniofacial area with the complaints of facial asymmetry due to painless swelling. And we discussed the clinical, radiological, and histopathological features of these cases with a brief review of the literatures.

Patients complaining of swelling and hematoma caused by contusion of the face can be easily seen in the emergency room. Most of the treatments were conservative treatments such as ice bag application, mild compression dressing, and massage. During the follow-up, fibrosis progression due to hematoma was frequently observed in the contusion site. When hematoma or fibrosis is confirmed, hyaluronidase (H-lase) 1,500 IU and 2 mL of normal saline were mixed and subcutaneously injected in crisscross manner. To evaluate the improvement of hematoma before and after hyaluronidase injection, three plastic surgeons evaluated using the Vancouver scar scale and compared preoperative and postoperative images. Hematoma and fibrosis after facial trauma improved after hyaluronidase injection for early treatment.

Post-traumatic hematoma formation is a common complication of contusion. If the hematoma is large enough to aspirate or drain, it can be treated quickly and appropriately. However, if the hematoma is small or concealed by local swelling, it may be overlooked and left untreated. In most cases, a hematoma will resolve following conservative treatment; however, associated infection or muscle fibrosis can occur. Herein, we present the case of a patient with a chin deformity caused by a post-traumatic hematoma. The deformity was treated using botulinum toxin and triamcinolone acetonide injections as minimally invasive treatments. The course of treatment was good.

The objective is to review a case of pneumoparotitis and to discuss how knowledge of this unique presentation is important when making differential diagnoses in emergency medicine. A patient with recurrent subcutaneous emphysema of the head and neck is reviewed. Stenson's duct demonstrated purulent discharge. Physical examination revealed palpable crepitance of the head and neck. Fiberoptic laryngoscopy and barium esophagram were normal. Computed tomography demonstrated left pneumoparotitis and subcutaneous emphysema from the scalp to the clavicles. This is an unusual presentation of pneumoparotitis and malingering. Emergency physicians should be aware of pneumoparotitis and its presentation when creating a differential diagnosis for pneumomediastinum, which includes more life-threatening diagnoses such as airway or esophageal injuries.

The emergence of vaccines for coronavirus disease 2019 (COVID-19) raises risk of possible adverse events from interaction between the vaccines and facial aesthetic care. A 47-year-old female with no medical comorbidities visited our emergency room due to midface painful swelling after 3 hours following receiving the second dose of the messenger RNA BNT162b2 COVID-19 vaccine. About 14 years ago, she underwent nonsurgical augmentation on the nasojugal groove with a calcium hydroxylapatite dermal filler. We performed incision and drainage under general anesthesia on the next day. During operation, yellowish pus-like materials bulged out. After an operation, we performed a combination therapy with antibiotics and methylprednisolone. Her symptoms improved day by day after surgery, and then a complete recovery was achieved at 3 weeks after the treatment. In conclusion, providers of aesthetic procedures are to be aware of the potential risks of such vaccines for patients who already had or seek to receive dermal filler injections.

Burkitt lymphoma (BL) is an aggressive form of non-Hodgkin's B-cell lymphoma found primarily in the pediatric population. In the oral cavity, this tumor can grow rapidly and often brings about facial swelling or development of an exophytic mass involving the jaws. A 5-year-old boy was referred for swelling and pain in the left mandibular area. The patient showed diffuse swelling on the left side of the mandible and firm-moderate tenderness upon palpation. An intraoral examination showed moderate mobility and sensitivity to percussion on the left primary first and second molars, without severe caries. A radiographic examination revealed complete loss of the lamina dura on the left primary second molar and permanent first molar. There was a radiolucent osteolytic lesion and destruction of the cortical bone of the left mandibular body. Based on the clinical, radiographic, and immunohistochemical findings, the patient was diagnosed with BL, and was referred to a pediatrician for systemic evaluation and intensive chemotherapy. Even before the completion of chemotherapy, the swelling resolved and the displaced teeth were relocated to a normal position. This patient showed a good prognosis due to prompt diagnosis and intensive chemotherapy. Early diagnosis and referral for treatment can prevent the development of BL.

The author observed a 35-year-old male patient who came to the Dental Infirmary of Kyungpook National University Hospital who had complained of gradual swelling on both side of the mandible for 15 years. As a result of careful analysis of clinical, radiological and histopathological findings, the authors diagnosed it as cementifying fibroma and obtained the results as follows: 1. In clinical examination, main clinical symptom was facial deformity due to gradual swelling on both side of the mandible. 2. In radiographic examination, radiolucent lesions with central radiopaque foci were seen on both mandibular body areas bilaterally, and cortical thinning and expansion of the mandibular body were seen buccolingually. And loss of lamina dura and root resortption of adjacent teeth were also seen. In histopathological examination, this lesion was composed of delicate interlacing collagen fibers interspersed by the fibroblasts and cementoblasts. And round or oval shaped basophilic masses of cementum-like tissue were observed in the connective tissue.
