Abstract
An ameloblastoma is a locally aggressive odontogenic tumour that commonly develops from the odontogenic epithelium within the jawbone. Here we present for the first time a case of a rare primary ameloblastoma in the middle ear cavity, along with some consideration of its treatment and a new classification. A 65-year-old woman presented with a left middle ear cavity tumour. Pathological examination led to the diagnosis of an ameloblastoma. We resected the tumour along with an extensive part of the middle ear mucosa, which made it difficult to have an adequate margin. It is recommended that the remaining bone be ground 2-3 mm beyond the visible margin after resecting the gross tumour. Therefore, several cases are treated with conservative surgery, including physicochemical treatment. This factor should be considered when designing treatment strategies as good alternatives in cases where resection with an adequate margin is difficult.

Abstract
This study examined Sal-like protein (SALL)1 methylation profiles in head and neck squamous-cell carcinoma (HNSCC) patients at diagnosis and follow-up, and evaluated their prognostic significance and value as a biomarker. SALL1 expression was examined in a panel of cell lines by quantitative reverse transcription PCR (qRT-PCR). Promoter methylation was determined by quantitative methylation-specific polymerase chain reaction (qMSP) and was compared to the clinical characteristics of 205 samples. SALL1 promoter methylation was associated with transcriptional inhibition and was correlated with disease recurrence in 31.7% of cases, with an odds ratio of 1.694 (95% confidence interval: 1.093-2.626; P = 0.018) by multivariate Cox proportional hazard regression analysis. SALL1 promoter hypermethylation showed highly discriminatory receiver operator characteristic curve profiles that clearly distinguished HNSCC from adjacent normal mucosal tissue, and was correlated with reduced disease-free survival in early stage T1 and T2 patients (log-rank test, P < 0.001). SALL1 methylation was significantly correlated with the methylation status of both SALL3 and CDH1. This study suggests that CpG hypermethylation is a likely mechanism of SALL1 gene inactivation, supporting the hypothesis that SALL1 might play a role in HNSCC tumorigenesis and could serve as an important biomarker.

Abstract
Introduction Small cell carcinoma/neuroendocrine carcinoma (SCNEC) of the oropharynx is uncommon. Two cases of SCNEC in an 81-year-old woman and in a 54-year-old man are presented here. Case description We have documented two cases of SCNEC arising in the oropharynx with evidence of high-risk human papillomavirus (HPV) infection. Histologically, both cases were classified as poorly differentiated SCNEC with high nuclear-to-cytoplasmic ratios and nuclear molding. Observations using a transmission electron microscope revealed membrane-bound neuroendocrine granules in some tumor cells. Both tumors expressed high levels of p16, a surrogate marker for high-risk HPV infection. HPV infection was confirmed in both cases using HPV polymerase chain reaction analysis; HPV subtype 16 was identified in one case and HPV subtype 18 in the other. Discussion and Evaluation SCNEC of the oropharynx is a rare and novel HPV-associated disease with neuroendocrine granules and aggressive clinical behavior. Conclusions Herein, we present two cases of SCNEC, focusing on its histologic features and treatment modalities. More studies are required to elucidate the pathophysiology of HPV-associated SCNEC in different organ systems.

Abstract
Conclusions This study suggests that long-term ventilation tube insertion is the first-choice surgical treatment for a 'sniff-type' patulous Eustachian tube (PET). When treating a refractory PET, it is important to determine whether the patient had a habitual sniff. Objectives PET patients were divided into two groups: patients with a habitual sniff (sniff-type PET) and those without a habitual sniff (non-sniff-type PET). This study examined the effects of ventilation tube insertion or silicone plug insertion in each group. Methods Surgical procedures such as ventilation tube insertion or trans-tympanic silicone plug insertion were performed for these patients. Tubotympanoaero-dynamic graphy (TTAG) was also performed to determine the mechanisms underlying these treatments. Results There were 11 cases (17 ears) of sniff-type PET and 20 cases (27 ears) of non-sniff-type PET. An improvement in symptoms was found in 72.7% of the patients who underwent silicone plug insertion (66.7% for sniff-type PET and 74.1% for non-sniff-type PET) and in 90.9% of the patients who underwent ventilation tube insertion for sniff-type PET. In TTAG assessments, many sniff-type PET patients showed significant synchronous changes at high levels of pressure (over 40 daPa) in the external auditory meatus and nasopharynx when performing a slight Valsalva manoeuvre (below 200 daPa).

Abstract
Background We report a rare case of a patient with a hypopharyngeal metastasis from breast cancer. Case presentation Isolated breast cancer metastasis to the hypopharynx has been previously reported in only one autopsy case. Herein, we report a 56-year-old woman with metastases to the hypopharynx almost 24 years after receiving a mastectomy and chemotherapy to treat primary breast carcinoma. We believe that she is the first patient to be treated for metastatic breast carcinoma to the hypopharynx. The hypopharyngeal tumor reduced in size after administration of an oral aromatase inhibitor. The patient has remained alive with a preserved larynx for three years. Conclusions Breast cancer metastasis to the hypopharynx is an extremely rare event.

Abstract
BACKGROUND Reconstruction with free jejunal graft (FJG) is often performed for patients with hypopharyngeal or cervical esophageal cancer. During reconstruction with an FJG after pharyngoesophagectomy, it is critical to intraoperatively detect venous anastomotic failure and subsequent venous malperfusion to avoid postoperative FJG necrosis. This study introduces a novel method for assessing blood perfusion in FJGs by using indocyanine green (ICG) fluorescence angiography. METHODS We used ICG fluorescence angiography to quantitatively assess FJG blood perfusion in archived fluorescence video files from 26 patients who had undergone FJG transfer. A software program "ROIs", was used to create a time-fluorescence intensity curve. We retrospectively measured the maximum fluorescence intensity at the terminal ileum and the duration (T1/2max) between when the intensity began rising and when it reached half of the maximum. RESULTS Among the 26 patients, 5 patients suffered venous anastomotic failure. In three of these cases, anastomosis was corrected intraoperatively; the other two patients underwent a second FJG transfer. Retrospective assessment showed that the mean T1/2max at the FJG serosae was significantly longer in these five patients than that in FJGs with good blood perfusion. Our analysis revealed that a T1/2max >9.6 s may be a good indicator of FJG venous malperfusion. CONCLUSIONS Quantitative analysis of ICG fluorescence angiography proved useful for detecting venous anastomotic failure of FJG, and may help to reduce vascular problems in FJG reconstruction.

Abstract
OBJECTIVE Evaluation of the clinical and pathological factors associated with the treatment and outcomes of external auditory canal (EAC) carcinomas. METHODOLOGY A retrospective review of clinical and pathological analysis was performed on 23 patients who were histologically diagnosed with EAC carcinomas and treated at Hamamatsu University hospital. We evaluated the clinical staging, treatment methods, pathological diagnosis (particularly squamous cell carcinoma, SCC), and patient outcomes. Main outcome measures include staging, treatment procedures, pathological features, and estimated survival rates. RESULTS The 5-year overall survival (OS) of study participants was 75.2% and the 10-year OS was 60.2% using the Kaplan-Meier method. The prognosis for SCC was poor compared with other carcinomas (p= 0.0462). The prognoses for SCC patients after treatment with surgery alone and after postoperative radiotherapy or chemoradiotherapy were significantly better than for patients with unresectable tumours (p = 0.0004 and p = 0.0001, respectively). There was no significant difference among the four tumour stage groups. Information about patients' survival status was obtained after a median follow-up period of 57.5 months (range, 7-151 months). CONCLUSION Our survival analysis data for carcinoma of the EAC demonstrates that SCC and unresectable cases are associated with poor outcomes. Outcomes for patients with operable disease more closely parallel the survival curves of patients with advanced stage T4 disease. Patients with SCC should be strictly categorized as cases with severe disease.

Abstract
CONCLUSION Habitual sniffing affects the pathogenicity and recurrence of cholesteatoma. Postoperative instructions requesting patients to cease sniffing may reduce the retraction and recurrence of cholesteatoma. OBJECTIVE To examine the relationship between tympanic membrane retraction and habitual sniffing in patients with cholesteatoma. METHODS We recruited 98 patients (102 ears) who were surgically treated for cholesteatoma by canal wall-down tympanoplasty (22 ears) or canal wall-down tympanoplasty with reconstruction methods (80 ears). We classified these patients into two groups on the basis of their preoperative habitual sniffing: habitual and non-habitual sniffers. The findings of the contralateral tympanic membrane were examined in each group and were classified according to the Tos classifications. Next, we evaluated the incidence of 1-year postoperative tympanic membrane retraction treated by the canal-down tympanoplasty with reconstruction method in the following three groups: non-habitual sniffing group, sniffing cessation group, and continual sniffing group. RESULTS In habitual sniffers, the Tos classifications of contralateral tympanic membrane were normal in 7% (3/41). In contrast, for non-habitual sniffers, the findings were normal in 39% (21/54). These results indicate that sniffing causes tympanic membrane retraction. The tympanic membranes of patients in the sniffing cessation group were largely normal after surgery. However, more than 50% of the patients who continued to sniff after surgery showed retraction or recurrent cholesteatoma.

Abstract
OBJECTIVES We analyzed the clinical features and surgical techniques used in cases of childhood congenital cholesteatoma of the middle ear. METHODS We studied 26 patients (26 ears) who underwent surgery for congenital cholesteatoma between January 1998 and December 2009, focusing on the location and type of cholesteatoma, the surgical procedures involved, and the results obtained. Patients with prior otologic procedures were excluded. A 4-stage system was used to grade the cholesteatomas. RESULTS The frequency of posterior-quadrant involvement and open-type cholesteatomas increased in the more advanced stages. Second-look operations were performed in 60% of stage III and 75% of stage IV cases; and residual cholesteatomas were found in 20% of stage III and 75% of stage IV cases. Of the cases evaluated both before and after the operation, 100% of stage I and II cases, 86% of stage III cases, and 50% of stage IV cases showed improvement in hearing function. CONCLUSIONS The staging system is relatively simple, while accurately reflecting clinical results. However, there are many differences between the anterior and posterior types of congenital cholesteatomas in surgical approach and postoperative progression that are not reflected in the classification systems and require further study. In addition, we reviewed the surgical procedures involved in anterior-quadrant cases, and propose a modified surgical procedure.

Abstract
CONCLUSION The study showed the value of using intravital microscopy (IVM) analysis for the study of neoangiogenesis. It demonstrated that the model and the analytical methodology could be used to evaluate in detail the effects of treatment strategies for solid tumours. OBJECTIVES Neoangiogenesis is a key component of tumour progression, invasion and metastasis. In clinical trials monoclonal antibodies specific for vascular endothelial growth factor - VEGF (bevacizumab) - have been shown to significantly affect tumour progression when given in combination with standard chemotherapy, and also to improve the overall survival of patients. For squamous cell carcinoma of the head and neck (HNSCC), we still await definitive evidence of the effect of such treatment. The present study was designed to investigate the anti-angiogenesis effect of beviacizumab in green fluorescent protein (GFP)-labelled HNSCC xenografts using IVM technology. METHODS We performed IVM and used image analysis for quantification of angiogenesis and of effects of bevacizumab on cell viability, combined with histochemical and immunohistochemical analysis to standardize the digital analysis of changes in tumour vascularization and cell viability. RESULTS We found significant effects of bevacizumab on angiogenesis and cancer cell survival in HNSCC. Repeated injections of bevacizumab were found to provide the greatest effects.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of epidermal growth factor receptor (EGFR) blockade on cell survival and on downstream signalling pathways using the monoclonal antibody cetuximab. METHODS We used three colon cancer cell lines, of which one was EGFR-negative, and two head and neck squamous cell carcinoma (HNSCC) lines. EGFR expression and gene copy number were measured by immunohistochemistry and FISH analysis, respectively. The effect of cetuximab, irradiation or the combination of both on cell growth was estimated by SRB assay. Western blotting was used to determine the phosphorylation of intracellular signalling proteins and cell cycle phase distribution was measured by flow cytometry. RESULTS The addition of cetuximab had only limited effects on cell growth, with a maximum inhibition of approximately 30%, but was correlated with the amount of protein expression and gene copy number of EGFR. When combined with irradiation, the effect of cetuximab was only additive and not dependent on the inherent radio-sensitivity of the cell lines. Persistent phosphorylation of Akt and/or p44/42 MAPK was detected by western blot in all of the cell lines, whereas there was no phosphorylation of Jak2 or STAT3. CONCLUSIONS None of these factors alone could predict the sensitivity to cetuximab. Rather, the results suggest that it might be necessary to determine the activation status of several intracellular signalling proteins to better predict the sensitivity to cetuximab treatment.
