Abstract
PURPOSE: To describe the detailed surgical technique used for harvesting and transplantation of autologous nasal mucosa grafts for ocular surface reconstruction, to evaluate the clinical results and utility of autologous nasal mucosa grafts in ocular surface diseases. METHODS: Autologous nasal mucosa was harvested from either the middle or inferior turbinate. It was transplanted on 11 eyes with severe ocular surface diseases including 4 eyes with chemical burns, 2 eyes with thermal burns, 1 eye with Stevens-Johnson syndrome, 1 eye with erythema multiforme major, and 3 eyes with extensively recurred pterygiums. Clinical outcomes were assessed based on ocular manifestation, epithelization, and visual acuity. RESULTS: The mean follow-up period was 19.9 months (range 13-32 months). Nasal mucosal tissues were safely excised, and their mucosal harvest sites were completely healed in 2 weeks without postoperative complications. All nasal mucosa autograft survived successfully with rapid epithelization, well-developed horizontal vascularization, and abundant mucin secretion. Clinical success, intact ocular surface epithelium without epithelial erosion more than 4 weeks, was achieved in all eyes. There was no recurrence of significant ulceration, conjunctivalization, fibrovascularization, symblepharon, or pterygium. CONCLUSIONS: Goblet cell transplantation using autologous turbinate nasal mucosa presents a promising treatment method in patients with severe ocular surface disorders.
