Introduction OCCULUSION OF THE external auditory canal may be due to a variety of causes ranging from foreign bodies to carcinoma. In the New England area exostoses of the canal are of common occurrence and occasionally cause complete occlusion so that surgery becomes necessary. Bony tumors, primarily found in the external canal (excluding exostoses), are rare. We are presenting a case of monostotic fibrous dysplasia involving only the temporal bone. Review of the literature reveals only two cases previously reported.14,15 Review of Fibrous Dysplasia Theterm fibrous dysplasiawas coined by Lichtenstein.9The entity has been recognized and described under other names:osteodystrophy fibrosa, osteitis fibrosa disseminata,andleontiasis ossea.1,2,8,11,5Polyostotic and monostotic lesions differ only in the fact that the former may include other extraskeletal lesions; for example, pigmentation, precocious puberty, cardiovascular anomalies, endocrine dysfunctions, besides involving more bones than one.10Harris has published an
