Mucous membrane grafting transfers tissue from the mouth or inner lip to the eyelids or conjunctiva to replace missing or scarred lining. It is used in cicatricial conditions where the normal mucosal surface has been damaged.
Indications
Conditions such as severe conjunctival scarring, symblepharon, lid margin keratinisation, or socket contraction after eye removal may require mucous membrane grafts. The graft provides a smooth, moist surface that protects the cornea or prosthesis.
- Tissue is harvested from sites like the lower lip or buccal mucosa
- The graft is thinned and sutured into the prepared recipient bed
- Donor sites in the mouth usually heal quickly but can be sore initially
- Multiple staged procedures may be needed in complex scarring
Outcomes
Successful grafting improves comfort, blink function, and the ability to fit contact lenses or prostheses. Long‑term stability depends on control of the underlying disease.
- Topical and sometimes systemic immunosuppression may be required
- Regular lubrication and lid care help maintain the new surface
- Grafts can shrink or scar, occasionally needing revision
- Careful planning with oculoplastic and corneal specialists optimises results
