Chyle leaks are uncommon complications after head and neck surgeries. Although uncommon, such a complication is noteworthy mention due to its perplexing diagnosis and management strategies. This scoping review aims to highlight and emphasize the diagnosis and management options proposed in the literature. A comprehensive search was performed in PubMed, Google Scholar, Cochrane Library, and Scopus databases and identified 617 articles that were reduced to 40 studies and reports after applying the eligibility criteria. Although numerous treatment options ranging from simple, conservative measures to invasive surgical procedures have been mentioned for low-output, high-output, and massive leaks, there is no concrete evidence on the best method. Thus, a combination of management options must be customized by case for optimum results.

$Sj{\ddot{o}}gren's$ syndrome (SS) is an autoimmune disease characterized by an autoimmune exocrinopathy involving mainly salivary and lacrimal glands. Apart from manifestations due to involvement of exocrine glands, patients with SS can present with muscular and neurological manifestations. Here, we report a rare case of a 59-year-old woman with primary SS, who presented with severe general toothache and masticatory muscle myalgia successfully treated with clonazepam. Although it was not certain that these symptoms could be originated from focal muscle dystonia or neurological changes that are associated with primary SS, our case suggested that comprehensive evaluation including neuromuscular examinations in the oral and maxillofacial area is needed in patients with SS.

We investigated the culture condition and effects of various growth factors on the culture of salivary gland acinar cells. Male, Sprague-Dawley rats (about 6 weeks old) were sacrificed and their submandibular, sublingual, and parotid glands were used as specimens. High oxygen level more than 90% and coating of Matrigel on culture dish were important factors to help increase the survival time of acinar cells, Proper concentration of enzymes such as collagenase and hyaluronidase during isolation steps was also important. Addition of various growth factors such as dexamethasone, insulin, transferrin, selenous acid, reduced glutathione, epidermal growth factor, isoproterenol, and putrescine in culture medium helped to increase lifetime of cultured salivary acinar cells.

저자는 방사선 동위원소가 부착된 lidocaine을 이온영동법과 국소도포법을 이용하여 16 마리의 가토의 구강점막에 침투시켜 그 침투량을 측정한 후 상호 비교하였으며, ephinephrine의 첨가가 lidocaine 침투에 미치는 영향에 대해 조사한 바, 다음과 같은 결론을 얻었다. 1. 이온영동법은 국소도포에 비하여 Lidocaine의 구강점막으로의 투여에 매우 효과적이었다. (p<0.05) 2. Ephinephrine 1/50,000 용액의 첨가는 국소도포법에 의한 lidocaine 침투량에 영향을 미치지 않았다. 3. Ephinephrine 1/50,000 용액을 첨가하여 이온영동법을 실시하였을 때, 모든 층에서 lidocaine의 침투량이 증가하였다.(p<0.05)

Ossifying fibromas are benign fibro-osseous tumors of mesenchymal origin. Although ossifying fibromas have principally been found in the jaw, they have also been reported in the frontal, ethmoid, sphenoid, and temporal bones, as well as the orbit and anterior cranial fossa. Ossifying fibromas affecting the jaw exhibit variable behaviors ranging from slow growth to occasionally aggressive local destruction. In the present article, we discuss a differential diagnosis considered for maxillary swellings and report a rare case of ossifying fibroma occurring in the maxilla.

Differential diagnosis of the malignant lesion and the benign lesion is critically important for the precise treatment. A clinician should diagnose in a comprehensive manner considering clinical, radiological, and histopathological perspectives. The lesion in the oral cavity in this study was clinically and radiologically malignant. However, the lesion was histopathologically benign. Surgical intervention was not performed except biopsy. The lesion improved after about one month of supportive medication after the biopsy. The importance of decision making process was emphasized in this report.

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.

We have conducted a retrospective study of 224 patients with the diagnosis of oral and maxillofacial infection who had been treated between 1988 and 1999 at Gyeong-Sang National University Hospital. This study was aimed to furnish the data of oral and maxillofacial infection and to aid diagnosis and treatment. The most common fascial space involved, as determined by clinical, radiologic, and operative findings, were the submandibular space(39.4%). The most frequent cause of oral and maxillofacial infection was odontogenic 68.8%. In the odontogenic cause, dental caries was the most common cause. Two-hundred three patients required surgical drainage of the abscess. Seventeen patients needed tracheostomy for airway control. The overall mortality was 0.9% despite aggressive anti-microbial therapy and early surgical intervention. All other patients had an uneventful recovery without major complication except osteomyelitis case(6.0%). The combination of early radiologic diagnosis, effective antimicrobial therapy, and intensive surgical management contributed to the good prognosis.

An osteolytic lesion with a small central area of mineralization and sclerotic borders was discovered incidentally in the clivus on the cone-beam computed tomography (CBCT) of a 27-year-old male patient. This benign appearance indicated a primary differential diagnosis of non-aggressive lesions such as fibro-osseous lesions and arrested pneumatization. Further, on magnetic resonance imaging (MRI), the lesion showed a homogenously low T1 signal intensity with mild internal enhancement after post-gadolinium and a heterogeneous T2 signal intensity. These signal characteristics might be attributed to the fibrous tissues, chondroid matrix, calcific material, or cystic component of the lesion; thus, chondroblastoma and chondromyxoid fibroma were added to the differential diagnosis. Although this report was limited by the lack of final diagnosis and the patient lost to follow-up, the incidental skull base finding would be important for interpreting the entire volume of CBCT by a qualified oral and maxillofacial radiologist.

Early diagnosis and treatment of osteomyelitis provide good prognosis and prevent severe complications. Therefore, it is important to early diagnose and treat before the bony changes are observed in conventional radiograms. Authors experienced three cases of early osteomyelitis, and scintigrams were useful to differentiate them from other diseases. The purpose of this report was to aid in the early diagnosis and treatment of osteomyelitis occurred in the jaws. The characteristic features were as follows: 1. In clinical examination, the patients complained mild pain and localized swelling in the jaws. 2. In radiographic findings, the conventional radiograms showed relatively mild bony changes in the jaws. 3. The more severe periosteal reactions were observed in radiograms in children than in adult patient. 4. It showed marked increased uptake of radioisotopes in all scintigrams. 5. The three phase bone scannings were helpful to differentiate osteomyelitis from soft tissue diseases.
