Osteoma is a benign slow growing osteogenic lesion, composed of well-differentiated mature bone tissue, characterized by the proliferation of compact or cancellous bone, almost exclusively found in the head and neck region. Central, peripheral and extra skeletal are the three variants of osteoma. Trauma, inflammation, developmental disorders and genetic defects are considered as the etiologic factors. Paranasal sinuses are the favourite locations of peripheral osteoma of the craniofacial region; frontal and ethmoidal sinuses being the common ones. Although, peripheral osteomas are usually benign, innocuous lesions, their size and prominent location on the visible parts of the face makes the surgical intervention necessary. We report case of multiple peripheral osteomas of forehead, without involvement of the frontal sinus, which is a rare variety.
骨瘤是一种生长缓慢的良性成骨性病变,由分化良好的成熟骨组织组成,其特征是密质骨或松质骨增生,几乎仅见于头颈部区域。骨瘤有中央型、外周型和骨外型三种变体。创伤、炎症、发育障碍和基因缺陷被认为是病因。鼻窦是颅面部外周骨瘤最常见的发病部位;额窦和筛窦最为常见。尽管外周骨瘤通常是良性无害的病变,但因其大小以及在面部可见部位的突出位置,手术干预是必要的。我们报告一例前额多发外周骨瘤病例,未累及额窦,此为罕见类型。
