    Orthognathic surgery is performed to correct jaw deformities and improve facial aesthetics, occlusal relations, stomatognathic functions and psychological states. However, various accidents and complications in orthognathic surgery may occur at any time during the course of treatment: in the preoperative judgment and planning, intraoperatively or postoperatively. Written information about possible complications and the recovery period and patients’ consent to the surgical procedure may be helpful in proper communication, which may reduce patients’ dissatisfaction. In the perioperative period, careful attention to possible complications, especially bleeding, nerve injury, airway narrowing and psychological problems, is required. By understanding and analyzing these possible complications, we can prevent and reduce the risks of incidental failures. The key points for perioperative management in orthognathic surgery are a reasonable surgical plan, mastery of the skill required, a safe and sure operation, and a careful wait-and-see approach with consideration of possible accidents and complications in the same manner as that for general surgical procedures.

    We report a case of Hodgkin’s lymphoma that involved the maxillary gingiva and bilateral cervical lymph nodes. The patient was an 89-year-old woman who complained about an ulcer in the right maxillary gingiva and swelling of the right cheek. Biopsy specimens taken from the gingiva showed typical Reed-Sternberg (RS) cells within a composite inflammatory milieu. Immunohistochemical analysis showed that the RS cells were positive for CD30, CD15, and CD20, and in situ hybridization analysis revealed that the cells were also positive for EBER1. Thus the disease was finally diagnosed as mixed cellularity Hodgkin’s lymphoma.

    Squamous papilloma associated with multiple confluent regions of growth involving large areas of the oral mucous membrane is called oral florid papillomatosis (OFP). OFP should be regarded as a premalignant lesion that can develop into verrucous carcinoma (VC). OFP can be treated using various methods, such as surgery, chemotherapy, radiotherapy, or cryosurgery. Choosing an appropriate treatment modality can thus be difficult.

     A 71-year-old man with multiple, large oral tumors was referred to our department. Although his condition was diagnosed as OFP, it was treated similarly to VC. He received chemotherapy with bleomycin (total dose, 120 mg). Consequently, the tumor was greatly reduced, and subsequent surgery was associated with minimal impairment of functions such as eating, swallowing, and conversation. Finally, functional impairment was minimal, even though surgery was performed five times.

     The case is reported with review of the past literature.

    We describe a case of sialolithiasis of the buccal mucosa with a fungal mass in a calculus of the minor salivary gland. An 87-year-old man was referred to our hospital because of a small nodule in the right buccal mucosa. On examination, an elastic, hard, painless, movable nodule, measuring 3 × 3 mm and located under the right buccal mucosa, was detected. The overlying mucosal surface was intact. Radiographic examination revealed no abnormalities in the right buccal region. We resected the nodule with the patient under local anesthesia. Histological examination of the resected specimen revealed lightly eosinophilic material with lamellar calcification and colonies of yeast-like fungus in a duct of the minor salivary gland. Comparative 26S ribosomal DNA sequence analysis of paraffin sections identified the fungus as Candida parapsilosis. This case suggests a potential role of mycosis in the etiopathogenesis of sialolithiasis.

    Although sailolithiasis generally occurs in the submandibular gland, submandibular stones rarely appear in children as compared with adults. We report a case of a submandibular gland stone in a child.

     An 11-year-old girl had swelling of left submandibular gland. A hilar stone of the submandibular gland that required submandibular sialoadenectomy was diagnosed at another hospital, and the patient was referred to our department for removal of the stone by minimally invasive endoscopic surgery. Computed tomography showed that the stone was about 3 mm in diameter. The submandibular gland stone was removed by endoscopic minimally invasive surgery with the patient under general anesthesia. There was no recurrence 2.5 years after removal of the submandibular gland stone.
