Oral mucoceles are mucin filled cavities and lined by ductal epithelium or covered by granulation tissue in retention or extravasation type respectively. The extra-vasation type is very common in the minor salivary glands (particularly in the labial glands), but very infrequent in the major salivary glands, whilst most of the retention cyst affect the major salivary glands. Partial obstruction of duct and spillage of mucin following trauma are the chief etiological factors. Though the two lesions are clinically indistinguishable, the patients are typically older than in the case of extra-vasation type. The case history along with heedful clinical examination of the lesion is crucial for diagnosing mucoceles correctly, but to avoid recurrences histopathological examination is mandatory. The surgical approach to mucoceles is the most common mode of treatment amongst various other techniques including cryosurgery, laser and so on.
口腔黏液囊肿是充满黏液的腔隙，潴留型黏液囊肿内衬导管上皮，外渗型黏液囊肿则分别被肉芽组织覆盖。外渗型在小唾液腺（尤其是唇腺）中非常常见，但在大唾液腺中极为罕见，而大多数潴留囊肿累及大唾液腺。导管部分阻塞和创伤后黏液外溢是主要病因。尽管这两种病变在临床上难以区分，但患者通常比外渗型患者年龄更大。病史以及对病变进行仔细的临床检查对于正确诊断黏液囊肿至关重要，但为避免复发，组织病理学检查是必需的。在包括冷冻手术、激光等多种其他技术中，手术切除黏液囊肿是最常见的治疗方式。
