A Case Report of Parotid Duct Transplantation to a Xerophthalmia Patient

Abstract

Surgical treatment was performed to a xerophthalmia patient. We transplanted a left parotid duct to a left conj uctival sac. A cuff of buccal mucosa removed around the duct orifice was necessary prior to the transplantation. It was utilized as a funnel to lengthen the duct. The result of Schirmar test was 0mm before surgery and 24mm after surgery. On the 2nd day profound epiphora was observed. After the transplantation a keratoepithelioplasty was carried out, but was not succeeded. The parotid dust was retransplanted back to its original place. Surgical technic of xerophthamia was discussed.
