RESUMO
OBJECTIVE: Clear cell carcinoma (CCC) is a rare, low-grade malignant neoplasm of minor salivary glands. Clear cell carcinoma is composed of monomorphic clear cells that contain glycogen within a hyalinized stroma. The microscopic diagnosis can be challenging, and the treatment strategy has not been established. METHODS: We report a case of a 56-year-old woman with CCC in the base of the tongue. A literature review, including 22 published cases and our case, was performed to clarify the clinical characteristics of CCC in the base of the tongue. RESULTS: The exophytic tumor showed no infiltration to the neighboring tissues. She underwent a local excision en bloc transorally and is free of the disease 15 months after surgery. In our review of 23 cases of CCC in the base of the tongue, 21 cases received surgical excision for the purpose of the primary treatment modality. The fact that the distinctive features of restricted site-related symptoms and the rare presentation of pain emerged was similar to previously reported cases of CCC. A relatively good prognosis was still indicated. CONCLUSION: We reveal the features of the unusual occurrence of CCC in the base of the tongue and consider the appropriate surgical approach for primary treatment.

OBJECTIVES: The first objective was to describe a novel case of migration of a broken dental needle into the parapharyngeal space. The second was to address the importance of simulation elucidating visualization of such a thin needle under X-ray fluoroscopy. METHODS: Clinical case records (including computed tomography [CT] and surgical approaches) were reviewed, and a simulation experiment using a head phantom was conducted using the same settings applied intraoperatively. RESULTS: A 36-year-old man was referred after failure to locate a broken 31-G dental needle. Computed tomography revealed migration of the needle into the parapharyngeal space. Intraoperative X-ray fluoroscopy failed to identify the needle, so a steel wire was applied as a reference during X-ray to locate the foreign body. The needle was successfully removed using an intraoral approach with tonsillectomy under surgical microscopy. The simulation showed that the dental needle was able to be identified only after applying an appropriate compensating filter, contrasting with the steel wire. CONCLUSION: Meticulous preoperative simulation regarding visual identification of dental needle foreign bodies is mandatory. Intraoperative radiography and an intraoral approach with tonsillectomy under surgical microscopy offer benefits for accessing the parapharyngeal space, specifically for cases medial to the great vessels.

Acute rhinosinusitis is frequently associated with secondary orbital infection, most commonly subperiosteal abscess. Although orbital subperiosteal abscess is a deadly disease that might lead to blind and cavernous sinus thrombosis, recent review of literature showed that immediate surgical intervention might not always be necessary for subperiosteal abscess. Orbital inflammation secondary to sinusitis is common in children, whereas orbital subperiosteal hematoma secondary to sinusitis is extremely rare, with only 11 reported cases, including one case in children. All the cases were treated with surgical intervention. Here we present a 12-year-old girl with rhinosinusitis and proptosis. Emergent endoscopic sinus surgery with partial removal of the lamina papyracea revealed dark brown fluid in the subperiosteal space. The patient was symptom-free 2 weeks after surgery. The present case was treated exclusively via an endonasal approach, whereas all 11 previous cases of subperiosteal hematoma were treated with external incision. The endonasal approach is favorable, especially for young female patients. Our review of literature shows that sudden onset, afebrile, and few signs of inflammation on blood test in patients with subperiosteal lesion may indicate subperiosteal hematoma. Surgery rather than antibiotic administration should be considered for the treatment of suspected subperiosteal hematoma. Treatment through only the endonasal approach is possible even if the hematoma is located in the roof of the orbit.

CONCLUSION: Lymph node swelling in the neck is one of the initial symptoms of malignant lymphoma (ML). The present study showed that clinical factors including higher age, higher level of maximum standardized uptake value (SUV-max) of positron-emission tomography, elevated serum lactate dehydrogenase (LDH), and elevated serum soluble interleukin-2 receptor (sIL-2R) were all useful indicators to suggest the diagnosis of ML, so may be helpful in the selection of patients for lymph node dissection. OBJECTIVE: Lymph node dissection is essential for the diagnosis of ML. The factors important for the diagnosis of ML were investigated, to establish surgical indicators. METHODS: Preoperative data including age, number and side of lymph nodes, SUV-max, serum LDH, serum sIL-2R, and size of lymph nodes were obtained from medical records. The cut-off level for each factor was calculated using the Youden Index for logistic regression analysis. RESULTS: Multivariate logistic regression analysis showed that the following factors were associated with ML: higher age (≥ 53 years), higher level of SUV-max (≥ 9.0), elevated serum LDH (≥ 203 U/L), elevated serum sIL-2R (≥ 2590 U/ml), with odds ratios of 3.7, 4.9, 3.7, and 11.9, respectively.

CONCLUSION: Conventional endoscopic sinus surgery (CESS) is useful for frontal mucoceles. A patient with short anterior-posterior distance and bone thickening may need an axillary flap, Draf type IIb, or Draf type III procedure. OBJECTIVE: To present outcomes of frontal mucoceles treated with CESS and predict risk factors for poor outcomes to help define surgical indications. METHODS: A consecutive clinical series was reviewed retrospectively. The authors performed CESS without agger nasi resection (Draf type IIa) for 13 frontal sinus mucoceles in 12 patients between October 2011 and July 2013. Patient age, sex, blood eosinophil count, history of operation and co-existence of acute infection were compared. For the condition of the frontal sinus, anterior-posterior distance and width of frontal recess, bone thickening of the frontal recess, bone absorption due to continuous pressure by mucocele and anatomy of the frontal recess was noted. RESULTS: All operations were done without a navigation system. The post-operative course was uneventful in all 12 patients, and all symptoms gradually receded. Among 13 mucoceles, one frontal sinus (7.7%) closed during follow-up.

On March 11, 2011, Japan's northeast Pacific coast was hit by a gigantic earthquake and subsequent tsunami. Soma City in Fukushima Prefecture is situated approximately 44 km north of Fukushima Daiichi Nuclear Power Plant. Soma General Hospital is the only hospital in Soma City that provides full-time otolaryngological medical care. We investigated the changes in new patients from one year before to three years after the disaster. We investigated 18,167 new patients treated at our department during the four years from April 1, 2010 to March 31, 2014. Of the new patients, we categorized the diagnoses into Meniere's disease, acute low-tone sensorineural hearing loss, vertigo, sudden deafness, tinnitus, and facial palsy as neuro-otologic symptoms. We also investigated the changes in the numbers of patients whom we examined at that time concerning other otolaryngological disorders, including epistaxis, infectious diseases of the laryngopharynx, and allergic rhinitis. The total number of new patients did not change remarkably on a year-to-year basis. Conversely, cases of vertigo, Meniere's disease, and acute low-tone sensorineural hearing loss increased in number immediately after the disaster, reaching a plateau in the second year and slightly decreasing in the third year. Specifically, 4.8% of patients suffering from these neuro-otologic diseases had complications from depression and other mental diseases. With regard to new patients in our department, there was no apparent increase in the number of patients suffering from diseases other than neuro-otologic diseases, including epistaxis, and allergic rhinitis. Patients suffering from vertigo and/or dizziness increased during the first few years after the disaster. These results are attributed to the continuing stress and tension of the inhabitants. This investigation of those living in the disaster area highlights the need for long-term support.

We report an extremely rare case of inflammatory myofibroblastic tumor of the posterior edge of the nasal septum. An 11-year-old boy presented with frequent epistaxis and nasal obstruction persisting for one year. Based on the clinical presentation and imaging studies, juvenile angiofibroma was suspected, but angiography suggested the possibility of another type of tumor. Transnasal endoscopic surgery found that the tumor protruded into the nasopharynx from the posterior end of the nasal septum. Histological examination identified spindle cells with immunoreaction for vimentin, smooth muscle actin, and anaplastic lymphoma kinase (ALK), but not for desmin and cytokeratin. This is a report of inflammatory myofibroblastic tumor mimicking juvenile angiofibroma. This case suggests that angiography is helpful in the differential diagnosis of epipharyngeal tumor in adolescence.
RESUMO
Isolated frontal sinusitis with mixed bacterial colonies is extremely rare and has not been described. We report a case of isolated frontal sinus forming mixed bacterial colonies that occurred in the previously exposed frontal sinus. The material in the frontal sinus was macroscopically similar to sinus fungus ball. Surgical strategy followed that for sinus fungus ball. The material could not be completely removed even with an endoscopic modified Lothrop procedure (Draf type III procedure). Additional external incision enabled complete removal of the remnant infectious substance. Histological examination detected two different types of organisms as intermingled bacterial colonies. External approaches to the frontal fungus ball have recently been replaced by the endonasal approach. Our case suggests that material trapped in a pit or small crevice in a frontal sinus may not be removed intranasally.
