Recurrent Myxoma of Maxilla / 대한이비인후과학회지

Myxoma is a relatively rare tumor of mesenchymal origin that can be found in numerous sites throughout the body including heart, skin, and subcutaneous tissue along with various sites in the head and neck. It is presumed to be originated from dental malformation or missing teeth, but occasionally myxoma without dental abnormalities is found giving arguments for its embryogenesis. Myxoma in the head and neck is usually managed by radical operation in order to prevent the possible recurrence. A case of recurrent myxoma of maxilla is described, which was treated with en-bloc removal via lateral rhinotomy incision. The purpose of this article is to present a case of myxoma of maxilla with a review of the literature and is to give a special emphasis on the proper modalities of treatment which minimizes recurrence and functional deficit.

Nasal Sensation of Airflow: Measurement, Reproducibility and Regional Differences

BACKGROUND AND OBJECTIVES: Although airflow sensation is believed to have a certain role in the subjective sensation of nasal patency, there are few studies that quantify and assess the sensation of nasal airflow. We designed an apparatus that delivers a pulsing jet of air to measure nasal airflow sensitivity. The aims of this study are to map out the airflow sensitivity of the nose, to evaluate the effect of decongestant on airflow sensitivity and to assess reproducibility. MATERIALS AND METHODS: The test sites were stimulated with a pulsing jet of air at gradually increasing velocities, and the minimum velocity at which the subject could detect the tactile sensation was recorded. The threshold velocities after phenylephrine spray were also measured and compared with the pre-decongestant values. The threshold velocities were obtained on two separate occasions to assess reproducibility. RESULTS: The nasal vestibule was more sensitive than the nasal mucosa to airflow, and the most sensitive area in the proper nasal cavity was the anterior end of the inferior turbinate. Sensitivity was not affected by decongestant spray. There was strong agreement between the first and second measurement values. CONCLUSION: Our method of measuring airflow sensitivity is believed to be useful in assesssing nasal airflow sensation.

Extramedullary Plasmacytoma of the Frontal Sinus / 대한이비인후과학회지

Extramedullary plasmacytoma involving the head and neck region is rare. Among the sites of involvement, nasopharynx, nasal cavity, paranasal sinus were the most frequent sites in descending order. Maxillary sinus is the most prevalent site of the paranasal sinuses with occasional involvement of the ethmoid and sphenoid sinus. However, the frontal sinus has not been reported to be the site of involvement as far as we know. Recently we experienced an extramedullary plasmacytoma of the frontal sinus in a 54 year-old male patient and report with literature review.
