Thermal burns of the larynx after swallowing hot foods or drinks are frequently common in children, but are known to be extremely rare in adults. We report the case of a male adult who, upon swallowing hot food, experienced a burn of the larynx with airway obstruction. Since airway obstruction usually occurs within hours of burn of the larynx, the importance of persistent airway management is emphasized in this case.

BACKGROUND AND OBJECTIVES: Accurate diagnosis of nasal fracture is difficult in many cases. Some reports showed that threedimensional facial computed tomography (3-D facial CT) is more effective than conventional facial computed tomography (conventional CT) in the diagnosis of nasal fracture. The purpose of this study is to prospectively evaluate the effectiveness of 3-D facial CT in diagnosis of nasal fracture. MATERIALS AND METHODS: From July 1, 2006 to January 31, 2007, 85 patients (83 men and 2 women, ranging in age from 29 to 46 years) visited the Armed Forces Capital Hospital within 2 weeks from nasal trauma. All patients prospectively underwent physical examination, lateral nasal bone view, Water's view, conventional CT, and 3-D CT. If any of definite crepitus on physical examination, or if definite fracture line on simple X-ray, or on conventional CT or on 3-D CT was found according to Hwang's criteria, that patient was confirmed to have nasal bone fracture. The diagnostic values of conventional CT and 3-D CT methods were analyzed by Pearson's chi-square test. RESULTS: Out of 85 trauma patients, 71 patients were diagnosed as having nasal bone fractures with the most common causes being, in the order of frequency of oc-currence, sports injuries and with other causes of blows, military training, works, and traffic accident. 28 patients showed nasal septal displace-ment or fracture. Conventional CT and 3-D CT were equally effective and had diagnosed 70 out of 71 fractures (98.6% of positive predictive value) and determined to be more effective than simple X-ray which had diagnosed only 50 fractures (70.4% of positive predictive value)(p=0.000). In the evaluation of nasal septum, conventional CT was proved to be more effective than 3-D CT since it diagnosed all 28 nasal deviation or fractures cases (100%) whereas 3-D CT diagonosed only 23 cases out of 28 (82.1%)(p=0.000). CONCLUSION: 3-D CT is not more effective than conventional CT in the diagnosis of nasal bone fracture. Moreover, conventional CT is better than 3-D CT in the diagnosis of nasal septal displacement or septal fracture.

Extramedullary plasmacytoma (EMP) is a rare plasma cell neoplasm that occurs mainly in the soft tissues of head and neck region, with the paranasal sinuses, nasal cavity and nasopharynx being the most common sites. Solitary EMP of the larynx is very rare but increasingly reported recently. Common sites of involvement in larynx in the order of frequency are the epiglottis, ventricles, vocal folds and ventricular folds. We report an extremely rare case of solitary EMP involving in the apex of arytenoids that was successfully treated by only surgical excision. Because solitary EMP of the apex of artytenoids is extremely rare, it should be included in the differential diagnosis for laryngeal mass. Also, solitary, small, pedunculated and localized EMP of the larynx could be completely removed by laryngeal microsurgery.

Basaloid squamous cell carcinoma is an unusual variant of squamous cell carcinoma that mostly arises in the upper aerodigestive tract. Etiologic factors such as tobacco, alcohol abuse and viral infection seem to be linked to this tumor. This tumor is highly aggressive, and is often presented at advanced stages with lymph node or distant metastasis. It most commonly occurs in the larynx, hypopharynx and the base of the tongue. Histologically, basaloid squamous cell carcinoma is characterized by a basaloid pattern often intimately associated with focal squamous differentiation, comedonecrosis, and stromal hyalinization. This tumor has been confused with adenoid cystic carcinoma and small cell undifferentiated carcinoma because of their histopathologic pattern, but is usually distinguishable in routine hematoxylin and eosin stained sections, or in rare cases, with the aid of immunohistochemical studies. We report a case of basaloid squamous cell carcinoma that occurred in the right palatopharygeal fold of the oropharynx, which is a distinctly unusual location.
