Patients with AIDS or ARC may present with parotid gland enlargement either initially or during the course of their disease. Of nine such patients, eight had unilateral gland enlargement, and one had bilateral disease. CT and MR scanning revealed that all patients except one had bilateral multiple intraparotid cysts. In addition, four of the nine patients clinically had cervical adenopathy, while all patients had adenopathy on scanning. We believe that the association of parotid cysts and cervical adenopathy is another manifestation of AIDS or ARC and, when found on scanning, should alert the clinician to the probable underlying condition.
In the past reconstruction of large auricular defects more than 2 cm have been repaired with the use of local skin flaps from various sites in multiple stages. This entails longer hospitalization and a poorer aesthetic result. We developed a postauricular myocutaneous flap that has been used successfully in five patients. The cosmetic results are superior to previously described reconstructive techniques. This flap, which can be used in immediate one-stage reconstruction, is based on the auricular branch of the posterior auricular artery. This vessel supplies the auricularis posterior muscle, the skin over the mastoid, and the cranial surface of the auricle. This vessel was dissected and found to be anatomically consistent in five cadavers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
