    Robotic surgery is ushering in a new era in surgery by offering patients better outcomes and has already become one of standard modalities in urology and gynecology. In the otolaryngological field, after the FDA clearance in 2009, transoral robotic surgery (TORS) has now been widely adopted by head and neck surgeons for treatment of benign and malignant conditions of the pharynx and larynx. TORS has also been adopted for treatment of parapharyngeal tumors, sleep apnea, recurrent nasopharyngeal cancer, retropharyngeal node metastasis. Another use of surgical robots in otolaryngology is thyroidectomy and neck surgery. Robotic thyroidectomy has been developed mainly by Korean surgeons and the technique evolved into robotic neck dissection. Despite the 2nd biggest market of surgical robots in the world, the access to surgical robot for otolaryngology is very limited in Japan because da Vinci has not been approved for otolaryngological field by pharmaceuticals and medical devices agency (PMDA) yet. Multi-institutional clinical study of TORS is currently conducted in order to clear PMDA. The limitations and future directions of surgical robots in otolaryngology are also discussed.

    We report herein on a 75-year-old woman with sinonasal-type hemangiopericytoma (HPC). She complained of nasal bleeding and a nasal tumor originated from the left nasal septum was found. It was successfully resected using endoscopic sinus surgery without preoperative embolization, because we were uncertain of its feeding artery. Its pathological examination gave a diagnosis of sinonasal-type of HPC. The sinonasal-type HPC is a rare benign sinonasal tumor, but WHO has classified it as a borderline malignancy, because it may have multiple relapses. Our patient remained free of relapse 36 months after the treatment.

    Ameloblastic carcinoma is a rare odontogenic tumor which arises in the mandible or maxilla. It is classified into the primary and secondary types, and the latter one is extremely rare.
    We report herein on a case of secondary ameloblastic carcinoma in a 36-year-old man who complained of indolent swelling at the left side of the mandible. CT and MRI images revealed a multiocular mass with bone destruction in the mandible, and the existence of the ameloblastic carcinoma was confirmed with multiple biopsies. The lesion was resected en bloc with a 1.5 cm safety margin, and reconstructed with an osteocutaneous fibula flap. The histological features of the tumor were consistent with secondary ameloblastic carcinoma. Neither recurrence nor metastasis has been found for one year after the surgery. The clinical, radiological and histological features of the ameloblastic carcinoma are discussed with reference to the relevant literature.

    We retrospectively analyzed the clinical characteristics of 193 consecutive patients with orbital blowout fracture who consulted us between March 2005 and July 2013. They were 140 males and 53 females ranging in age from 2 to 91 years (average; 36.6 years). About two thirds of patients (122/193=63.2%) were in their teens, twenties and thirties.
    There were 87 floor fractures, 56 medial-wall fractures and 50 combined fractures. Seventy-two patients did not show spontaneous improvement of diplopia within the initial follow-up period of 1–2 weeks after injury, and underwent surgery (surgical cases). The other 121 patients were conservatively managed (nonsurgical cases). The percentage of the medial wall fracture was significantly higher in the nonsurgical cases than in the surgical cases (42/121=34.7% vs. 14/72=19.4%, P=0.023). The average interval between injury and surgery was 13.9 days (range; 0–53 days). Endoscopic sinus surgery was performed in the majority of the cases (62/72=86.1%) solely or in combination with the transmaxillary or transorbital approach. Complete recovery was achieved in 41 patients (56.9%), partial recovery in 28 patients (38.9%), and no improvement in 3 patients (4.2%). Patients who reached complete recovery within 1 month were significantly younger than those who did not (25.6±14.0 vs. 38.2±23.1 years, P=0.048). The Hess area ratio at the initial consultation was significantly higher in the nonsurgical cases than in the surgical cases (92.2±13.9 vs. 75.9±21.8%, P<0.001). Patients with complete recovery were likely to have a longer indwelling period of their balloon catheter than those without (6.9±1.3 vs. 6.4±1.1 days, P=0.082). The surgical outcome did not show significant correlation with the interval between injury and surgery.
    These results suggest that the indication of surgical treatment for orbital blowout fracture should be determined after the initial follow-up period of 1–2 weeks from injury, taking the patient’s age, type of fracture and Hess area ratio into consideration, unless the extraocular muscle(s) are incarcerated.

    A 70-year-old woman was admitted to our hospital with acute heart failure, and was managed on a ventilator for 3 days. She was extremely hoarse after extubation, and was referred to the otolaryngology department, but there were no abnormal findings. Three months after discharge, she was admitted with extreme hoarseness. Tumors were observed on the bilateral vocal cords which had almost closed the airway, and which we determined as requiring surgical resection. At first the patient underwent tracheotomy and the tumors were resected. Since then, no new granulation has been permitted.
    Because of the choking hazard, a huge granuloma requires surgical resection. Prevention is the most important strategy in intubation granulomas, so we believe that it is important to eliminate as many factors involved in the development of granuloma as possible.

    We have been applying superselective intra-arterial chemoradiotherapy (SIACRT) to advanced squamous cell carcinomas of the maxillary sinus and upper gingiva since 2009. We reported the outcomes of SIACRT in this journal recently. SIACRT is a promising therapy to preserve the patient’s quality of life both during and after the treatment, without sacrificing the cure rate. However, we cannot but use imaging to evaluate the SIACRT response, because visual observation of the lesion is difficult with the maxillary sinus not fenestrated in our therapeutic method. We use 18F-FDG-Positron emission tomography-computed tomography (PET/CT) to evaluate the SIACRT response. This report shows the PET/CT findings of the same patients we reported in this journal recently, before and after SIACRT. We also mention squamous cell carcinoma antigen (SCC) of the patients as a guide to the response evaluation. The 1st PET/CT around 3 months after SIACRT showed false positive in many of the cases. Another PET/CT 1–2 months later could evaluate the SIACRT response more correctly. SCC might help for the evaluation using PET/CT.

    Pediatric salivary gland carcinomas are a rare neoplasm with a prevalence of 0.9 per million people. On the other hand, 30 to 40% of pediatric salivary gland tumors are malignant. We report herein on a case of submandibular gland carcinoma in a child. The patient was a 9-year-old girl with a right submandibular swelling from three years previously. Ultrasonography revealed a tumor in the right submandibular gland. Fine needle aspiration cytology was performed, and the tumor was diagnosed as class III. There were some atypical findings associated with a benign tumor based on ultrasonography and cytology findings. To make a definite diagnosis, excision of the right submandibular gland was performed. The frozen section showed malignant findings, thus neck dissection was added. The final pathological diagnosis was a low-grade mucoepidermoid carcinoma. There has been no recurrence or metastasis for 12 months without adjuvant therapy. An operation should be considered even in children if there are suspicious findings of malignancy.

    The 126 patients were surgically treated for thyroid tumors in our hospital between April, 2002 and July, 2013. Female patients were more frequent than males. In 66.7% of the cases the tumors were benign (adenomatous goiter was the most frequent) and malignant tumors accounted for 33.3% (papillary carcinoma was the most frequent). There were patients who had no subjective symptoms, when their thyroid tumors were discovered incidentally during a routine medical examination. In fine needle aspiration cytological diagnosis, the sensitivity value was 96.0% and specificity value was 84.2%, and accuracy value was 87.1%. In TNM classification, 71.4% of the cases comprised T1 and T2. N1 accounted for 52.4% and N0 for 47.6%. Among those patients with malignant tumors, 2 died. The remaining 40 patients are alive at present. Recurrence was found in 6 cases.

    We report herein on a case of interdigitating dendritic cell sarcoma (IDCS) of a neck lymph node. A 43-year-old man was seen for left neck swelling. The left neck was found to have a smooth and soft tumor. We found atypical cells with fine needle aspiration cytology, and performed a cervical lymph excisional biopsy. Diagnosis was confirmed by histology and immunostaining. After the lymph node biopsy, additional radiation therapy was performed. Generally, diagnosis of IDCS is difficult. In this case, the tumor lesion was limited to a cervical lymph node and fine needle aspiration cytology suggested the possibility of malignancy. Treatment resulted the patient’s being desease-free at 18 months after radiation therapy.

    We present herein an 85-year-old patient with advanced hypopharyngeal carcinoma who developed thrombocytopenia during treatment with cetuximab plus radiotherapy. He had a medical history of diabetes mellitus and atrial fibrillation and was taking 3.5 mg of oral warfarin per day. At the time when the third dose of cetuximab was administered, the patient experienced a high-grade fever—thought to be an infusion reaction—followed by thrombocytopenia, which improved with platelet transfusion. After radiotherapy was finished, a hematoma was observed in the iliopsoas muscle on a CT scan. The prothrombin time-international normalized ratio (PT-INR) was elevated to an extremely high level of >8.0, which caused by warfarin. Thrombocytopenia owing to cetuximab is a very rare but adverse event that may occur severely in elderly patients. Therefore, it is necessary to choose the treatment carefully for them. In addition, patients with carcinoma receiving anti-coagulant therapy should be assessed for risk factors and frequently monitored for blood coagulation during anti-cancer treatment.

    Deep neck abscesses represent a severe infection that requires prompt treatment. We report herein on cases of deep neck abscess requiring surgical drainage. The subjects of this study were 25 patients treated in our department between January 2009 and June 2013. They consisted of 12 males and 13 females ranging in age from 5 to 89 years with an average of 60 years. Hypertension and diabetes were predominant in their medical histories and the major causes of the abscesses were pharyngolaryngitis, tonsillitis and dental infections. All patients underwent emergency surgery on the day of consultation. In bacteriological examinations, 19 patients tested positive with aerobic bacteria being detected in four patients and anaerobic bacteria in 17. Tracheotomy was jointly conducted in 20 patients and four patients underwent repeat surgery. The mean length of hospital stay was 31 days and three patients were in hospital for eight weeks or longer. All three were elderly patients aged 75 or above and two had also undergone tracheotomy. Diabetes did not contribute to prolonging hospital stays. Among the factors prolonging hospital stays were advanced age, tracheotomy and the accompanying swallowing difficulty.
