Milia en plaque (MEP) is a rarely-described benign, cutaneous dermatosis, characterized by numerous tiny milia within an erythematous base which usually occurs around the ears. We report a case of a well-defined, linear MEP arising from the right side of the forehead to the nasal bridge. This case is of particular interest as the site of occurrence is uncommon and the shape of lesion is atypical.

BACKGROUND AND OBJECTIVES: The intricate anatomy of the temporal bone has always been difficult to visualize. In this regard, the advantages of computer-assisted reconstruction of temporal bone based on image data from computed tomography (CT) are widely recognized. The goal of this study was to investigate the usefulness of three-dimensional (3D) reconstruction of computed tomography in determining the anatomy and topographic relationship of various important structures. SUBJECTS AND METHOD: For 40 ears of 20 patients with various otological diseases, 3D reconstruction based on image data from spiral high-resolution CT was performed by segmentation, volume-rendering and surface-rendering algorithm on a personal computer. The scanning was carried out in axial plane with technical factors of 140 kV, 100 mAs, 1 mm thickness, and 1 second scanning time. A software (Vworks(TM) 4.0, CyberMed Inc, Korea) was used for image processing. RESULTS: We were able to demonstrate the 3D display of the middle and inner ear structures. The computer-assisted measurement of reconstructed structures demonstrated the anatomic details comprehensively, which improved the surgeon's understanding of their spatial relationship, and provided many details that could not be easily measured in vivo. CONCLUSION: The 3D reconstruction of temporal bone CT can be useful in demonstrating and thus understanding the anatomical structures of temporal bone. Also, its clinical applications are inestimable. But it is necessary to confirm the correlation between 3D reconstructed images and histologic sections through the validation study.

Endochondral pseudocyst of the ear is considered to be a benign, asymptomatic condition seen infrequently in clinical practice. It is an intracartilaginous cyst devoid of epithelial lining and filled with a sterile, viscous, straw-colored fluid. It is important to remove the pseudocyst to prevent recurrence and good esthetic outcome. We experienced a case of a 59-years-old man with an endochondral pseudocyst of his right auricle. To our knowledge, this is the first report in Korea, so we report this case with a review of the literature.

Otalgia is a common symptom with diverse causes due to its complex sensory innervations. It can be broadly classified into two groups. Primary (otogenic) otalgia is defined as pain resulting from ear diseases and secondary (referred) otalgia arises from pathologic processes and structures other than the ear. Its workup is complex and no simple algorithm exists. In this review, authors collected and analyzed articles on otalgia and described anatomical considerations and clinical evaluation of otalgia, and outlined various causes and treatment options for primary and referred otalgia.
