We report a case of a 46-year-old man who had giant squamous cell carcinoma originating from the occipital scalp, invaded occipital bone and dura mater. In the preoperative conference, the dermatologist in our hospital suggested that if the subtotal tumor reduction, reconstructive surgery and chemoradiotherapywere effective, the survival period of this patient would hopefully be more than 2 years. Therefore such therapy was selected and performed, the tumor disappeared completely for 17 months and the quality of life has been maintained. This suggests that squamous cell carcinoma originating from skin does not easily cause metastasis compared with that from lumen in the head and neck region. This multidisciplinary team including a dermatologist, head and neck surgeon, neurosurgeon, radiation oncologist, plastic and reconstructive surgeon, and dentistry and oral surgeon was successful.

We present a patient with metastastic renal cell carcinoma to the ethmoid sinus. A 68-year-old male consulted with complaints of left epistaxis and nasal cavity tumor. His status was post left total nephrectomy for renal cell carcinoma. The histological diagnosis was renal cell carcinoma (clear cell type). We performed skull base surgery for total ethmoid sinus resection. We report on this case and discuss metastasis of renal cell carcinoma to the head and neck region.

We report a case of a dumb-bell tumor of the parotid gland in which the tumor was strangulated by the facial nerve.A 66-year-old female was admitted with a 6-year history of a subaural bulging mass. Computed tomography and magnetic resonance imaging showed a dumb-bell tumor occupying the deep lobe of the left parotid gland and the left parapharyngeal space. Resection of the tumor was performed via a transcervical approach. The tumor was strangulated by the ramus of the mandible, the base of the skull and the facial nerve. In order to conserve the facial nerve, fraction excision of the tumor was performed. Pathological examination showed pleomorphic adenoma. Facial paresis occurred after surgery and recovered in 3 months.

Pleomorphic adenomas usually occur in the major salivary glands, and rarely in the nasal septum.We describe here a rare case of a Pleomorphic adenoma originating from the nasal septum treated by endoscopic nasal surgery. A 77-year-old man was admitted to our hospital because of epistaxis. The rhinoscopic examination showed a vascularized nasal polyp-like mass located in the nasal septum. It was elastic in consistency. Endoscopic examination revealed a smooth-surface mass measuring 2 x 2 cm in diameter. Nasal axial contrast-enhanced CT scan demonstrated a well circumscribed solid mass with a slightly enhanced rim in the right nasal cavity with no evidence of bone destruction. The patient underwent adequate surgical excision using nasal endoscopy. On histologic examination, the specimen was found to be a pleomorphic adenoma. Thereafter, the patients showed no evidence of recurrence at more than one year later. It is concluded that endoscopic nasal surgery is a useful option for a pleomorphic adenoma of the nasal cavity.

A neurogenic tumor is comparatively rare among non-epithelial tumors arising from the nasal cavity.The patient was a 30-year-old woman who complained of frequent epistaxis. A nasal cavity hemangioma was suspected by various image examinations. We resected the tumor after embolization of nutrient blood vessels under DSA. The pathologic examination revealed a ganglioneuroma. The ganglioneuroma is a tumor that originates from the sympathetic nervous system, like the ganglioneuroblastoma and the neuroblastoma. The ganglioneuroma is a benign tumor showing differentiation in the highest degree as a sympathetic nervous system origin tumor.

Leiomyoma is a benign smooth muscle tumor most commonly found in the uterus, skin, and gastrointestinal tract, and is rare in the nasal cavity. We report a rare case of leiomyoma of the nasal septum. A 57-year-old male was admitted with a history of complete right nasal obstruction for several months, without epistaxis, rhinorrhea, or headache. The tumor was removed by endoscopic endonasal surgery.

Malignant tumors during pregnancy are rare. Strategies for the treatment of laryngeal cancer during pregnancy are not simple, because we must assess both the mother and the fetal condition.We report a case of laryngeal cancer in a 32-year-old female. She had suffered from dyspnea in the supine position for 4 months, at 15 weeks of pregnancy. She visited the hospital after expelling tumor mass during an episode of severe coughing. The tumor was limited to the posterior wall of the subglottic area by fiberscopic observation and MRI. Histological examination revealed a squamous cell carcinoma of stage T1N0. We removed the tumor using a laryngofissure at 22 weeks of pregnancy. The histopathological diagnosis was mucoepidermoid carcinoma. She is free of the disease and her child is growing normally, at 2 years and 5 months after the surgery.

We report three cases of tuberculous otitis media. These cases, including a 54-year-old male, 17-year-old male and 41-year-old female, were initially diagnosed as acute otitis media at Miyazaki Medical College Hospital and a related hospital from 1978 to 2001. During the treatment, they exhibited atypical findings, such as painless otorrhea and necrosis of a tympanic membrane, and the antibiotics ordinarily used were not effective. Such clinical course suggested tuberculous otitis media, and then a definitive diagnosis was made. It is difficult to make an early diagnosis. Several clinical criteria published in recent years indicate that otoscopic findings are relatively unique for tuberculous otitis media. Therefore, it is important to recognize these characteristic findings as the signs of this disease.In the treatment of acute otitis media, we must keep in mind that tuberculous otitis media should be suspected if the patient shows intractable otorrhea without otalgia.

We present our experience of performing adenoidectomy with ICC200, a radio frequency surgical system which can provide both ENDO CUT and soft coagulation modes. The ENDO CUT handpiece was designed simulating the Beckmann adnoidectome. Our results from all 8 cases showed that less bleeding and shorter of operation time could be achieved by using this device. The surgical skill was found to be similar to traditional adenoidectomy, and the residual adenoid tissues approaching the posterior edge of the nasal septum still required to be removed with forceps or a punch. Soft coagulation is especially helpful to control the bleeding in this area, and is also effective for the bleeding from a surgical wound produced by ENDO CUT.

In total maxillectomy, the entire upper jaw including tumor is freed and removed en bloc from the facial skeleton, depending on the situation of the tumor. We perform total maxillectomies with an image-guided navigation system.The navigation system helps us to confirm the anatomical location and decide the extent of removal in real-time. Especially, it is useful when the zygoma, the frontal process, the orbital floor and the pterygoid process are divided.We must understand the 3-D anatomy and decide the appropriate extent of removal, depending on the situation of the tumor. The navigation system plays a supplementary role in total maxillectomy. Moreover, it has the potential to help reduce the extent of removal, ensuring oncological safety.

Our method of ossicular reconstruction type III and type IV is introduced. Before the ossicular reconstruction, we have to completely control inflammatory and infectious lesion in the middle ear cavity, and treatment should provide sufficient aeration for the tympanic cavity.It is necessary to grasp the relationship between the stapes and the tympanic membrane by measuring the tympanic cavity structure before trimming the material. We must understand not only the distance but also the three-dimensional alignment between the stapes and the tympanic membrane. According to the result of measuring, material must be adequately shaped for each case. For a type III procedure, the common length of material is between three and four millimeters, and for type IV, the length must be between six and seven millimeters.We have to pay careful attention to prevent inner ear damage and facial nerve injury at the time of insertion of material, and should find the most adequate position for the stability of material.

Using an operative endoscope is very common in sinus surgery. In tonsillectomy, however, it is unusual to use an endoscope. We have developed use of an endoscope for tonsillectomy. How to use an endoscope in tonsillectomy is reported. The endoscope was very useful in tonsillectomy, especially to guide the operative procedure and to perform safe surgery.
