Dermoids, or hairy polyps, are rare lesions affecting the head and neck region. To date approximately 120 cases have been recorded. They arise during early embryogenesis and are invariably benign. Unlike the more differentiated types of teratoma, hairy polyps are derived from only two germinal layers, ectoderm and mesoderm. Most originate in the oro-nasopharyngeal region, either as pedunculated or sessile masses. They usually present at, or soon after, birth with signs of upper aerodigestive tract obstruction. Treatment consists of surgical removal. In young children with airway compromise, the expertise of an experienced paediatric anaesthetist is essential. Three new cases of hairy polyp are described to add to the present literature. Two originated in the nasopharynx and one in the oropharynx. Interestingly, one patient, a neonate, also suffered from severe osteopetrosis. All lesions were removed by simple surgical excision under general anaesthesia. There were no operative or post-operative complications.
皮样囊肿，即毛发状息肉，是一种罕见的累及头颈部区域的病变。迄今为止，已记录了约120例病例。它们在胚胎发育早期出现，且始终为良性。与分化程度更高的畸胎瘤类型不同，毛发状息肉仅由外胚层和中胚层两个胚层发育而来。大多数起源于口鼻咽区域，呈带蒂或无蒂肿块。它们通常在出生时或出生后不久出现上呼吸道消化道梗阻的症状。治疗方法为手术切除。对于气道受损的幼儿，经验丰富的儿科麻醉师的专业知识至关重要。本文描述了三例新的毛发状息肉病例以补充现有文献。两例起源于鼻咽部，一例起源于口咽部。有趣的是，一名新生儿患者还患有严重的骨硬化症。所有病变均在全身麻醉下通过简单的手术切除。无手术或术后并发症。
