REVIEW
Deborah Watson, Bharat Panuganti
This article provides a review of the surgical and nonsurgical options available to manage a variety of auricular scars. The basics of wound healing are discussed in addition to the etiology of keloids and the cauliflower ear. Many auricular scars can be revised with scar excision techniques, but separate discussions for the treatment of keloids and the cauliflower ear are provided. The management plan for auricular scarring requires appropriate patient counseling regarding the risk of recurrence in keloids, regrowth of scar tissue in cauliflower ears, scar hypertrophy at the line of closure, widening of the scar, and persisting ear contour deformities...

BACKGROUND: Several treatments are available to treat the keloid scar. Keloids have the tendency to recur after surgical removal and new treatments for keloid scars include radiotherapy, cryotherapy or compressive therapy. Topical treatments have been also used to treat this pathology, such as injections or medical device applications. CASE REPORT: A 33-year-old man came to our attention and we treated him for a keloid scar located between the ear's helical tubercle and the ante-helix upper root of the left ear...

Basal cell carcinomas (BCCs) are one of the most frequent cutaneous malignancies. The majority of BCCs are reported to occur on the auricular helix and periauricular region due to ultraviolet light exposure. Despite the frequency of BCCs, those that develop within scar tissue are rare, and the phenomenon of keloid BCCs has rarely been reported in the literature. Keloid collagen within BCCs is associated with morphoeiform characteristics, ulceration, or necrosis. Extensive keloid collagen is often seen in BCCs of the ear region, a site prone to keloid scarring...

An 11-year-old Tanzanian girl presented with diffuse verrucous lesions of varying morphology, scarring alopecia, and keloid scars over the face with a predilection for the ears. Physical examination revealed dark keratoderma and patches of hypopigmentation near the midline of the dorsal trunk (Figure 1a). Her forearms were densely covered by verrucous lesions with the exception of a clear linear patch on the dorsal aspect of the left forearm (Figure 1b). The perioral area was notable for white spires projecting from verrucous papules (Figure 1c) while the oral mucosa and teeth appeared normal on visual examination...

BACKGROUND: Keloids represent a challenging problem. Surgical excision remains the definitive treatment for immediate lesion debulking, but recurrence rates are reported to be 45 to 100 percent. The authors present a staged reconstructive approach using a dermal regeneration substrate and epidermal grafting to minimize recurrence and donor-site morbidity. METHODS: Keloids were completely excised down to normal subcutaneous tissue or perichondrium. A bilaminar dermal regeneration matrix was approximated to the entire wound, with the silicone lamina oriented superficially...

BACKGROUND: Keloids of the ear are common problems. Various treatment modalities are available for the treatment of ear keloids. Surgical excision with intralesional steroid injection along with compression therapy has the least recurrence rate. Various types of devices are available for pressure therapy. Pressure applied by these devices is uncontrolled and is associated with the risk of pressure necrosis. We describe here a simple and easy to use device to measure pressure applied by these clips for better outcome...

The most critical function of the epidermis is to prevent water loss and maintain skin homeostasis. Disruption of the functional skin barrier causes delayed wound healing, hypertrophic scarring, and many skin diseases. Herein, we show that reduced hydration increases the expression of S100 protein family members, S100A8/S100A9, in stratified keratinocyte culture and human ex vivo skin culture. Immunohistological analyses show that S100A8/A9 are highly expressed in the epidermis of human hypertrophic scar and keloid tissues...
