Clinical 22-case study of hereditary hemorrhagic telangiectasia subjects undergoing nasal dermoplasty
Hereditary hemorrhagic telangiectasia (HHT)-a systemic autosomal dominant disorder adversely affecting skin, mucous membranes, and visceral blood vessels-typically shows epistaxis. In this pathological condition, even minor stimulation may cause bleeding and hemostasis is unlikely to occur. Subjects with HHT showing severe nasal bleeding require nasal dermoplasty (ND). We report our experience in 22 cases of HHT undergoing ND seen from January 2000 to November 2009. Average age at surgery was 55.8 years. Since April 2008, we modified ND, cut the harvested skin graft from the lateral thigh in halves and spread each strip on the anterior halves of the nasal cavity. Placement was circumferential in the sequence of agger nasi, nasal valve, septum, floor, and inferior turbinate. Before this technique was used, bleeding could not be controlled in 3 of 14 cases. Two of the 3 had histories of arterial embolization. Subjects undergoing the new technique have enjoyed improved quality of life.
