The submandibular gland is one of the major salivary glands, salivary diseases frequently occuring site due to its anatomical weakness. This retrospective study evaluated data pertaining to history, sex, operation method, age distribution, diagnosis through the chart, operation record, radiographs, histologic finding of 51 patients operated on for the submandibular gland excision from 1986 to 1995 in our hospital so that we improve on the understand of the salivary gland diseases. The results were as follows ; 1. The chief complaints was mass, swelling mainly. 2. The ratio of affected site was 47.1 : 51 in left : right respectly, both sites was 1 case especially. 3. The ratio of men to women was 56.9 : 43.1 4. The operation performed all through the extraoral approach. 5. The sialolith presented at 24 cases. 6. The most patients had a two weeks duration period. 7. The age distribution was the third decade(29.4%), the second decade(27.5%) in order. 8. The symptoms accompanied the chief complaints was pain(37.3%), mass(17.6%), swelling(13.7%), trismus(13.7%) in order. 9. The diagnosis was sialadenitis with stone(S.W.S.) (45.1%), sialadenitis without stone(S.W.O.S.) (17.6%), pleomorphic adenoma(P.A.) (15.7%), abscess(Abs) (5.9%), tuberculosis(Tbc) (5.9%) in drder.

Purpose: To evaluate the clinical and radiologic findings of the postoperative maxillary cysts (POMCs) and investigate the relationship between lesion size and clinical symptoms depending on the time elapsed after radical maxillary sinus surgery. Methods: A total of 29 patients who were diagnosed with POMCs at Chonnam National University Dental Hospital were selected. Clinical and radiologic findings were investigated. POMC cases were divided into two groups: those with <24 years between maxillary sinus surgery and POMC diagnosis and those with >24 years. The chi-square test was used to compare the differences between the two groups. Results: The average period from surgery to POMC detection was 24.32 years; however, the period could not be confirmed in four patients. The average patient age was 52.75 years, and 12 (41.3%) patients were in their 50s. POMC-related clinical symptoms were as follows: buccal pain and swelling, dull pain, toothache, abscess, sensory abnormality, and asymptomatic. Twenty (69.0%) cases showed unilocular radiolucency and 9 (31.0%) revealed multilocular radiolucency. Seven cases (35.0%) were misdiagnosed as odontogenic lesions, resulting in the delayed treatment of POMCs. No statistical significance was found between the two groups with respect to symptoms, expansion to the surrounding area, presence of secondary cysts, and mesiodistal length of cyst on cone-beam computed tomography (CBCT) images. However, the buccopalatal length of the cyst on CBCT images was significantly different between the two groups. Conclusions: The buccopalatal length of POMCs observed on CBCT images was related to the time elapsed since surgery. The lack of awareness of POMCs may lead to misdiagnosis as an odontogenic infection and delayed treatment. Therefore, dentists must recognize the clinical and radiologic features of POMCs to differentiate it from dental infections.

Purpose: Culture-based methods for microbiological diagnosis and antibiotic susceptibility tests have limitations in the management of orofacial infections. We aimed to profile pus microbiota and identify antibiotic resistance genes (ARGs) using a culture-independent approach. Materials and Methods: Genomic DNA samples extracted from the pus specimens of two patients with orofacial abscesses were subjected to shotgun sequencing on the NovaSeq system. Taxonomic profiling and prediction of ARGs were performed directly from the metagenomic raw reads. Result: Taxonomic profiling revealed obligate anaerobic polymicrobial communities associated with infections of odontogenic origins: the microbial community of Patient 1 consisted of one predominant species (Prevotella oris 74.6%) with 27 minor species, while the sample from Patient 2 contained 3 abundant species (Porphyromonas endodontalis 33.0%; P. oris 31.6%; and Prevotella koreensis 13.4%) with five minor species. A total of 150 and 136 putative ARGs were predicted in the metagenome of each pus sample. The coverage of most predicted ARGs was less than 10%, and only the CfxA2 gene identified in Patient 1 was covered 100%. ARG analysis of the seven assembled genome/metagenome datasets of P. oris revealed that strain C735 carried the CfxA2 gene. Conclusion: A metagenomics-based approach is useful to profile predominantly anaerobic polymicrobial communities but needs further verification for reliable ARG detection.

급성 상악동염의 원인으로는 급성 상기도 감염이 가장 흔하며 함치성 낭종 등의 치성원인에 의한 경우는 상악동염의 10-12%를 차지한다. 함치성 낭종은 주로 치과에서 우연한 방사선학적 검사에 의해 발견되며 소아에서는 드물게 보고되고 있다. 함치성 낭종이 과잉치와 동반되었을 때 주위 상악골의 파괴와 치근의 흡수를 야기하거나 침범된 치아의 변위를 유발할 수 있으므로, 조기 진단과 적절한 치료가 중요하다. 본 증례에서 콧물과 코막힘으로 부비동염으로 진단받았던 9세 남자 환아가 2개월 뒤 좌측안면부 연부조직염으로 내원하여 시행한 방사선학적 검사에서 좌측 상악동에 과잉치와 동반된 함기성 낭종이 관찰되었으며, 치료로 외과적 절제술을 시행하였다. 저자들은 소아에서 부비동염의 원인으로 과잉치를 동반한 감염된 함치성 낭종을 경험하였으며, 부비동염의 진단과 치료에 있어 항생제 치료로 호전되지 않거나 증상이 지속될 시 단순 상기도감염 합병증 외에 다른 질환의 감별을 고려할 것을 당부하는 바이다.

Extension of advanced odontogenic infection from deep neck fascial spaces into the mediastinum is heralded by chest pain, dyspnea, fever, and radiographic demonstration of mediastinal widening. The critical care should be done in a team approach by multiple medical and dental departments, such as, oral & maxillofacial surgery, otolaryngology, anesthesiology, chest surgery, and infection medicine. Especially, fluid & drug therapy, adequate incision & drainage and systemic supportive psychosedation care are important. But, acute hyperventilation can be produced by several distinct causes: severe anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The orofacial fears about acute pain, trismus, dysphagia, swelling and oral surgical treatment lead to the severe anxiety and increased blood catecholamine level by stress. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the care, hyperventilation was occurred during psychosedation and local anesthesia for incision and drainage of the masticatory fascial space abscess with deep neck infection & mediastinitis. We suggest that the dental patient with advanced odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.
