“…10 The ablative lasers (Er: YAG and CO 2 ) have been reported to be used to treat the SN. 11,12 Verma and colleagues study showed appropriate results of the SN treatment with the CO 2 laser. Still, in 26 % of the cases, the patients demonstrated hyperpigmentation and mild atrophic scarring (13 % of cases) in the posttreatment period.…”

Introduction: Sebaceous nevus (SN) is a benign skin hamartoma with a potent transformation in benign or malignant tumors in adolescents or adults. Due to the most common location in the esthetic zone, an SN makes patients seek a dermatologist for cosmetic concerns on the face or neck. The surgical excision of a large-sized SN in the esthetic zone may require reconstruction with a skin flap and be associated with recurrences and scar formation. Case Report: We describe the successful treatment of the large-sized neck SN with copper vapor laser (CVL) for the first time. A left-sided neck SN (linear size of 27 mm) in the 24-year-old Caucasian female completely resolved after eight CVL sessions. The settings were as follows: average power accounted for 0.8-1.0 W, with a ratio at green (511 nm) and yellow (578 nm) wavelengths of 3:2. The pulse duration was set as 20 nanoseconds, the repetition rate 16.6 kHz, the exposure time 200 ms, light spot diameter of 1 mm. The CVL treatment resulted in the complete disappearance of the SN without remote side effects such as hyperpigmentation, scarring or recurrences 24 months after the treatment. The patient was satisfied with the excellent cosmetic results. Conclusion: The CVL treatment of the SN provides the most relevant result due to the complete elimination of SN cells and the remodeling of the vascular bed supplying the involved areas.

“…Epidermal nevi in the external auditory canals have been treated with carbon dioxide (CO 2 ) laser ablation, resulting in excellent cosmesis and no evidence of repigmentation at 8 months follow-up. 38 Short-pulsed CO 2 laser ablation has also been used to treat congenital melanocytic nevi on the tragi, resulting in high patient satisfaction and no recurrence or scar formation at 1 year follow-up. 37 By contrast, one study investigating Q-switch-mode Alexandrite laser treatment of congenital nevi on the earlobe failed to achieve histologic clearance.…”

BACKGROUND As one of the defining features of the face, the ear influences perceptions of beauty. Despite its significance, comparatively little is known about rejuvenation options for the ear. OBJECTIVE To provide a comprehensive review of minimally invasive options for earlobe rejuvenation. METHODS & Materials: Cochrane, Embase, and PubMed were used to identify articles exploring minimally invasive treatments for ear rejuvenation. RESULTS Topical medications, peels, fillers, lasers, photodynamic therapy, and dermabrasion are safe and efficacious for managing a variety of concerns related to earlobe aesthetics. CONCLUSION Numerous minimally invasive treatment modalities are available for earlobe rejuvenation; further investigation is needed to design a grading system and treatment algorithm.A lthough much deliberation has been given to the aesthetic improvement of various facial subunits, comparatively little has been explored regarding the earlobe. Highlighting the cultural significance of this structure, ear piercing is a millennia old tradition, observed in ancient civilizations around the globe. 1 Auricular deformity can lead to significant psychological morbidity 2,3 ; conversely, there is robust evidence demonstrating improved psychological outcomes after treatment of auricular defects. [4][5][6][7] From 1997 to 2013, cosmetic auricular surgery skyrocketed by 81%, which partially reflects the increasing popularity of gauge ear piercing. 2,3 Awareness of earlobe aesthetics has also been rekindled by the mask mandates of the COVID-19 pandemic, which have left fewer components of the face remaining exposed. To date, there is a paucity of studies investigating minimally invasive treatments for earlobe ptosis, actinic damage, and dyschromia. This review will explore the treatment options found to be effective for earlobe rejuvenation, while also extrapolating from existing literature on therapies successful in other cosmetically sensitive regions. MethodsTo identify evidence-based treatment regimens for earlobe rejuvenation, an online search was conducted using the Cochrane, Embase, and PubMed databases. Search terms included ear, cosmetics, cosmetic techniques, esthetics, fillers, laser, laser therapy, rejuvenation, and skin aging. Initially, this yielded 1,590 results. Articles published before 1990 or in languages other than English were excluded. References from results were also examined for pertinent articles. After reviewing these studies and excluding irrelevant results, the search distilled 42 articles for review. Anatomic Properties of the EarExternal ear development begins as 6 mesenchymal buds that gradually fuse; the lobule forms last. By 5 years of age, the ear reaches 96.7% of its adult width and 86.6% of its adult length. 4,5 While the anterior upper two-thirds of the auricle consists of cutaneous tissue adherent to the perichondrium, the posterior auricle contains adipose tissue between the perichondrium and overlying skin, lending the helical rim its distinct appearance (Figure 1a). 8 Lacking ...
