ABSTRACT
OBJECTIVES: Oncological and functional results of open conservation surgery for hypopharyngeal cancer have been desired. METHODS: We performed a chart review of 33 patients with hypopharyngeal cancer who underwent open conservation surgery. Oncological and functional results were evaluated in surgery with primary closure (Group A) and surgery with reconstruction (Group B). Postoperative functions were evaluated by interval to resumption of oral intake, Functional Outcome Swallowing Scale (FOSS) and Communication Scale (CS). RESULTS: Five-year disease-specific and overall cumulative survival rates by Kaplan-Meier method for all cases were 95.7% and 82.3%, respectively. Duration from surgery to full oral intake was 12 days in Group A and 14 days in Group B. FOSS rates were 83.3 in Group A and 95.5 in Group B. CS was 0 in both groups. CONCLUSION: Oncological and functional results of open conservation surgery were comparable to those with transoral surgery and chemo/radiotherapy. Our technique represents a reliable treatment for hypopharyngeal cancer.
ABSTRACT
Based on the complexity of functional anatomy, a small infarction in the medulla can produce various types of clinical symptoms or signs depending on the location of this infarction. We describe the case of a 46-year-old man who presented with sudden onset of body lateropulsion to the left side and numbness of the ipsilateral fingers. 3-tesla diffusion-weighted magnetic resonance imaging with a section thickness of 2 mm revealed a small infarction in the dorsal part of the left middle medulla. To our knowledge, this is the first case report describing vestibular dysfunction apparent upon otoelectrophysiological examination but without vestibular symptoms or signs except for body lateropulsion.
ABSTRACT
OBJECTIVE: Vascular malformations may appear anywhere in the body; 14-65% are in the head and neck. There are several treatments (sclerotherapy, surgery, laser treatment, and embolization, etc.), but standardized guidelines for these treatments are lacking. We conducted a retrospective review of venous or capillary malformations of the head and neck, and analyzed the epidemiology, pathology and treatment. METHODS: We retrospectively reviewed 67 patients with pathologically diagnosed venous or capillary malformations of the head and neck; we analyzed the location, pathology and treatment, as well as recurrent/residual cases. RESULTS: The oral cavity (59%) and nasal cavity (35%) were the most common locations. The frequency of each pathological type depended upon location. Surgery was undertaken in 65 cases, and sclerotherapy done in one patient. Sixty-one cases (92%) had resectable lesions. However polycystic masses (≥3 cysts) and large masses (diameter, ≥5cm) were significantly difficult to cure by single treatment. CONCLUSIONS: Surgery is indicated for localized small vascular malformations. However if the lesions ≥5cm or polycystic lesions were more likely to recur after surgery alone in our study population.

BACKGROUND: Primary intraosseous squamous cell carcinoma is very rare. We report two cases of primary intraosseous squamous cell carcinoma of the jaw, one arising from an odontogenic cyst and the other arising de novo. METHODS AND RESULTS: The first case was a 76-year-old man with right mandible pain. A panoramic radiography and computed tomography revealed a large mandibular radiolucency. A biopsy revealed squamous cell carcinoma, and radiotherapy and hemimandibulectomy were performed. The second case was a 50-year-old man with lymph node swelling on the left neck. Squamous cell carcinoma of the lymph node was suspected after fine needle biopsy. After left neck dissection, histological testing of the odontogenic cyst revealed squamous cell carcinoma, of which the mandible was thought to be the primary site. CONCLUSION: Our two cases have no recurrence, and panoramic radiography was a useful tool in the detection of mandible disease.
