• If available, an electrosurgical or radiofrequency unit (e.g., Ellman Surgitron) with a fine cutting needle or wire works well to excise the tissue (see Chapter 30, Radiofrequency Surgery [Modern Electrosurgery]).

2 A wheal of lidocaine without epinephrine placed circumferentially around the entire base of the ear will provide good anesthesia (ear block; see Chapter 8, Peripheral Nerve Blocks and Field Blocks). The concha and ear canal retain sensation. Use of the circumferential block as opposed to injection directly into the lobe avoids distortion of the local anatomy.

3 Excise the defect with a no. 15 or 15c blade, a no. 11 pointed blade, or with the electrosurgical or radiofrequency unit (e.g., Ellman Surgitron; level 2, pure cut, Varitip or fine needle; Figs. 71-3 through 71-5). If the defect is a large hole, it is often easier just to excise all the way through the lobe to create a “V” (see Fig. 71-3). Various sterilized objects with a flat surface have been used to support the lobe during the excision because it is so flaccid, but with gentle traction by the nondominant hand, the lobe should remain stable. The radiofrequency unit makes this step easier, especially if the defect is a hole and you are trying to preserve the lower intact rim of tissue (see Figs. 71-4 and 71-5). Care should be taken to excise a smooth line and to treat the exposed subcutaneous tissue and wound edges extremely gently. If needed, skin hooks should be used. Absolutely avoid grasping the skin edges with forceps; this delivers a crushing-type force, induces unnecessary trauma, and increases scarring. Earlobe cysts are removed and repaired in the same manner (Fig. 71-6).
