Matrixectomy: If your doctor believes the destruction of the nail matrix is necessary after removing the toenail, he or she will perform a partial or full matrixectomy (or matricectomy), which is permanent toenail removal by applying a chemical agent (most commonly phenol or sodium hydroxide) to the matrix.
Pterygium removal surgery eliminates the abnormal tissue from the cornea and sclera (white of the eye). The older, standard surgical technique left a bare hole in the conjunctiva (the surface of the eye) where the pterygium was removed.Unfortunately, this led to a high rate of pterygium regrowth. newer technique fills the gap in the conjunctiva left by the removal of the pterygium with a graft of tissue removed from under the eyelid. This graft is then stitched in place. A downside of this approach is that the stitches can cause discomfort while the eye heals. This healing period can last for weeks.
