Intralesional injections are the mainstay of the treatment for keloids. However, injecting through thick keloidal tissue is a challenge as a result of excessive proliferation of dermal fibroblasts and haphazardly arranged thick hyalinized collagen.
To overcome the difficulty of injection, clinicians use dermajet to deliver intralesional drugs, although it is expensive and has deeper penetration. Another method of making keloid tissue soft is cryotherapy; however, it can give rise to bullae, ulceration, secondary infection, and dyspigmentation.
To soothe the process of injecting pharmacological agent into hard keloids, we propose that a 26G needle be inserted into keloid tissue and moved in a to and fro manner in different directions to create multiple tunnels. Thereafter, the intended drug is injected with ease owing to creation of these tunnels [Video 1]. A 26G needle was found to be suitable for tunneling [Figure 1].

This simple technique allows drug delivery into keloids with ease due to the tunnels created. On account of this, we have termed this technique as “tunneling technique.”
