Nail abrasion.
Certain diseases of the nail complex cause hyperkeratosis or alterations of the shape of the nail plate. These conditions may be painful, may decrease the penetration of topical medicaments and may be ugly. The nail plate abrasion, performed with dermabrader device or sandpaper, has application in patients suffering from onychomycosis, psoriasis, subnail infections and haematomas. The technique facilitates the collection of scales for mycological examination, decreases treatment time (of topical monotherapy) for onychomycosis and provides greater comfort for the patient by reducing nail plate thickness. It can also be useful for the partial removal of the nail plate in cases of haematomas and subnail infections. Nail abrasion is an effective and inexpensive method, easily applied in either nail pathologies with hyperkeratosis of the nail plate or in those requiring partial removal of the plate.
