ABSTRACT
A cyst following implantation of respiratory epithelium during surgical procedures has been documented only rarely. A variety of names have been attached to this lesion: respiratory mucocele, respiratory implantation cyst, surgical ciliated cyst, and surgical (implantation) cyst. In seven prior case reports, the interval between the initiating surgical procedure and diagnostic biopsy of the resultant well-circumscribed radiolucency and histopathological demonstration of distinctive pseudostratified ciliated columnar epithelial lining has varied from 4 to 40 years. In the case reported here, chin augmentation used "residual maxillary bone" as the donor tissue and likely transplanted sinonasal mucosa into the mandible during orthognathic surgery, resulting in a painful anterior mandibular cyst lined by respiratory epithelium that was ablated 16 years later.
ABSTRACT
The oral and perioral manifestations, both clinical and radiographic, of leprosy have been reviewed. In tuberculoid leprosy, sensory and motor nerve involve of the trigeminal and facial nerves is not uncommon, although involvement of all nerves supplyng the oral and related structures occurs. In Lperomatous leprosy, facial and oral involvement with ulceration, scarring, and typical lepromas occurs, resulting in numerous esthetic and functional deformities. Nerve involvement may become manifest if the disease progresses. There may be transition and overlap of signs and aymptoms between these two types. The case of lepromatous leprosy decribed here involved rather typical facial changes; however, there was no intraoral pathosis other than gingivitis and periodonditis. Perhaps most notable, in this patient there were maxillary and mandibular radiographic changes which have not been described previously.
