Abstract

BACKGROUND High-frequency ultrasound has been utilized in dermatology to visualize superficial cutaneous structures. Axillae are often target of treatments for hair removal, for spot clearing, and for skin conditions such as hyperhidrosis, bromhidrosis, and hidradenitis. Detailed knowledge of armpit thickness can help improve existing therapies and increase their effectiveness. OBJECTIVE To describe the mean skin thickness of axillae, by further investigating possible correlations with variations in age, sex, and body mass index (BMI). MATERIALS AND METHODS Axillae were divided into 5 quadrants, 1 central and 4 peripherals. Skin has been assessed by ultrasonography, measuring the distance from epidermis surface to dermal depth, in millimeters, for each of the regions. RESULTS Thirty healthy patients participated, most of them were female (n = 22; 73%), mean age 50 years (26-70 years). Most patients have maximum thickness in the center of axillae (87%). Average skin thickness in the central region was 3.1 ± 0.4 mm. There was significant difference between axillary thickness in central and peripheral regions (p < .05). On the periphery, the mean thickness was smaller (1.8 mm) without significant variation between the squares. There was no significant variation of skin thickness by sex, age, and BMI. CONCLUSION This study shows a difference between thickness of axillae in the central region and in its periphery.

用高频超声波评估腋窝皮肤厚度。

背景在皮肤科中，高频超声已被用于观察表层皮肤结构。腋窝通常是脱毛、祛斑以及治疗多汗症、狐臭和日光性皮炎等皮肤病的治疗目标。对腋窝厚度的详细了解有助于改进现有疗法并提高其有效性。材料和方法腋窝被分为 5 个象限，1 个中央象限和 4 个外围象限。结果30 名健康患者参与了此次研究，其中大部分为女性（22 人；73%），平均年龄为 50 岁（26-70 岁）。大多数患者腋窝中心的皮肤厚度最大（87%）。中央区域的平均皮肤厚度为 3.1 ± 0.4 毫米。腋窝中心区和外围区的皮肤厚度有明显差异（P < .05）。外围区域的平均厚度较小（1.8 毫米），各方阵之间无明显差异。性别、年龄和体重指数对皮肤厚度没有明显影响。
