    Recently, dental implant surgery has begun to be routinely performed in many dental hospitals and institutions. Consequently, complications associated with dental implants have also increased.
    We report four cases of odontogenic maxillary sinusitis caused by dental implant placement and/or maxillary sinus augmentation surgery.
    These cases raise the possibility of two pathogenetic mechanisms underlying the development of odontogenic maxillary sinusitis caused by dental implant placement and/or maxillary sinus augmentation surgery. One is the surgical procedure for the placement of dental implants causes odontogenic infections such as odontogenic maxillary sinusitis, while odontogenic infections, such as odontogenic maxillary sinusitis, can also be caused by chronic infection of adjacent teeth, such as apical periodontitis.
    There is no consensus for the management of the fixture (implant body) or the filling materials used in maxillary sinus augmentation surgery when a dental implant causes intractable odontogenic maxillary sinusitis. Endoscopic sinus surgery is indicated for intractable odontogenic maxillary sinusitis caused by dental implant placement.

    Neoplasms arising from the palate are uncommon. We conducted a retrospective review of 5 cases of palatal tumors in which surgical resection was performed after preoperative diagnosis by local examination, MRI, and fine-needle aspiration cytology or biopsy. Of the 5 tumors, two were pleomorphic adenomas, one was a basal cell adenoma, one was a canalicular adenoma, and one was an unclassified benign tumor, all originating from the minor salivary glands. Two of the 5 benign tumors were suspected to be malignant tumors by local examination, MRI, as well as pathological examination. Because mucosal ulcers or bone erosion can sometimes be seen even in cases of benign tumors of the palate, it is not easy to make a precise preoperative diagnosis of whether the tumor is benign or malignant. Canalicular adenoma should be borne in cases with mucosal ulcers or bone erosion, so as to enable correct diagnosis and prompt treatment.

    There have been many reports on the perioperative care and complications related to OSA, however, few studies have investigated these in relation to sleep apnea surgeries. We considered the usefulness of noninvasive positive pressure ventilation after sleep apnea surgery. The subjects were 12 patients (sex ratio men: women=11: 1, average age 46.2) in whom sleep apnea surgery was performed under general anesthesia at our hospital. We measured the nighttime ODI3 (Oxygen Desaturation Index 3%) on the day of the operation (using BiPAP), and one day before and after the operation (without BiPAP), using a pulse oximeter and compared the changes. In all cases, the ODI3 was significantly lower on the day of the operation when BiPAP was used, and significantly higher on the day after removal of the BiPAP mask. Also, the cardiopulmonary status remained extremely stable on the operation day. In all 12 cases, no complications were recognized after the surgery. Among the many perioperative care problems associated with sleep apnea surgeries, we recognized a significant difference in oxygenation in the postoperative patients. Under this particular circumstance of ‘sleep apnea surgery’, more studies related to safer perioperative care and establishment of standards will be needed in the future.

    Primary thyroid lymphoma is uncommon and accounts for less than 1-5% of all thyroid malignancies. The clinical presentation is usually a progressively enlarging neck mass, but patients may also present with symptoms of dysphagia, hoarseness and choking, or a cold thyroid nodule. The histopathologic types in the majority of cases are diffuse large B-cell lymphoma and extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue. The treatment for thyroid lymphoma consists of chemotherapy (CHOP regimen), rituximab combined with CHOP, and/or radiation therapy. The treatment strategy would be selected based on the histopathologic type and extent of the disease. In the emergency setting of airway obstruction, before a definitive diagnosis is made, steroid therapy, endotracheal intubation and tracheostomy may be required for airway management.
