Methods for the subungual treatment of diseases or disorders of the nail unit including infections, especially fungal infections, and nail psoriasis involving the toenails and fingernails are described. The methods provide a technique for placement of a drug-containing composition subungually with reduced risk of hematoma formation and improved patient comfort.

1. A method for treating onychomycosis, comprising: creating in a nail unit with onychomycosis a subungual channel at a position between a lateral nail fold and a longitudinal midline of the nail plate;after said creating, inserting into the subungual channel a composition comprising an active agent
1. A method for treating onychomycosis, comprising: creating in a nail unit with onychomycosis a subungual channel at a position between a lateral nail fold and a longitudinal midline of the nail plate;after said creating, inserting into the subungual channel a composition comprising an active agent; anddepositing the composition in the subungual channel such that at least a portion of the composition extends beyond a visible proximal edge of the onychomycosis. 2. The method of claim 1, wherein said creating comprises creating a subungual channel that extends distally from a proximal edge of the nail plate to a visible proximal edge of fungal infection. 3. The method of claim 1, wherein creating comprises creating a subungual channel using a blunt tipped cannula. 4. The method of claim 1, wherein creating comprises creating a subungual channel by debriding subungual debris. 5. The method of claim 1, wherein inserting the composition comprises inserting an applicator comprising a needle in which the composition is placed. 6. The method of claim 5, wherein the composition is a solid composition disposed in a tip of the needle. 7. A method for treating onychomycosis, comprising: inserting into a nail unit with onychomycosis a composition comprising an active agent for treatment of onychomycosis, wherein said composition is inserted in a region defined by a longitudinal midline of the nail plate and a lateral nail fold at a point of greatest curvature of the nail plate, wherein said composition is deposited in the channel such that a portion of the composition extends proximally beyond the proximal edge of fungal infection. 8. The method of claim 7, wherein inserting comprises inserting an applicator comprising a needle. 9. The method of claim 8, wherein the composition is a solid or semi-solid that is dispensed from the needle. 10. The method of claim 8, wherein the composition is a solid composition disposed in a tip of the needle. 11. The method of claim 8, wherein inserting comprises inserting the composition subungually in a channel that extends from a distal edge of the nail plate to a visible proximal edge of fungal infection. 12. A method for treating onychomycosis, comprising: identifying a visible proximal edge of fungal infection in the nail unit of the subject; anddepositing a composition comprising an active agent for treating onychomycosis subungually between the nail plate and the nail bed at approximately the visible proximal edge of fungal infection. 13. The method of claim 12, wherein identifying comprises visually identifying a visible proximal edge of fungal infection. 14. The method of claim 12, wherein depositing comprises depositing the composition such that a proximal edge of the composition extends proximally beyond the proximal edge of fungal infection. 15. The method of claim 12, further comprising creating in the nail unit a subungual channel at a position between a lateral nail fold and a longitudinal midline of the nail plate. 16. The method of claim 15, wherein said creating comprising creating a subungual channel by insertion of an instrument at a point of greatest curvature in a region defined by a longitudinal midline of the nail plate and a lateral nail fold. 17. The method of claim 16, wherein the instrument is a cannula inserted to form a subungual channel that extends from the insertion point to approximately the proximal edge of fungal infection. 18. The method of claim 15, wherein said creating comprising creating a subungual channel by insertion of an instrument at a point of onycholysis in a region defined by a longitudinal midline of the nail plate and a lateral nail fold. 19. The method of claim 15, wherein creating a subungual channel comprises debriding subungual debris. 20. The method of claim 15, wherein creating further comprises depositing an anesthetic in the subungual channel. 21. The method of claim 12, wherein the composition is a solid composition, a semi-solid composition or a solution. 22. The method of claim 12, wherein the composition is a solid or a semi-solid composition comprised of a biodegradable polymer. 23. The method of claim 22, wherein the biodegradable polymer is polyethylene glycol. 24. The method of claim 12, wherein the active agent is an antifungal agent. 25. The method of claim 24, wherein the antifungal agent is released by erosion or degradation of the polymer over a period of at least about 2 weeks. 26. The method of claim 12, wherein the composition comprises between about 65-80 weight percent anti-fungal agent. 27. The method of claim 26, wherein the antifungal agent is terbinafine hydrochloride.
