Schwannomas are benign, solitary, encapsulated tumors that may originate at any site of the peripheral nervous system, with the exception of the olfactory and optic nerves. Schwannomas of the base of tongue are very rare, and only sporadic cases are documented. The tongue base represents a challenge for surgeons. Carbon dioxide (CO ) laser might provide an effective surgical option for such lesions because of the easy access to the lesion, the bloodless surgical field and optimum epithelization of wounds. We present an unusual case of pedunculated schwannoma of the tongue base treated via transoral CO -assisted excision. We also provide a review of the available literature, in English language, on humans. The authors searched the PubMed database and Google up to July 2018. The following search terms were applied: and combined with and . Titles and abstracts were screened, and, then, only supraglottic (hypopharyngeal) tongue base masses were considered. Fourteen articles were included in this review, reporting 17 cases. The age of the patients ranged from 9 to 39 years, affecting predominantly females. Dysphagia and lump sensations were the most common presenting symptoms, and the mean follow-up period range was 1.5 to 60 months (mean = 13 months). There was no evidence of recurrence in any of the cases. We could conclude that tongue base schwannomas are rare. Transoral complete excision of the tumor is the treatment of choice. CO laser surgery is a minimally invasive treatment option that has been performed in few reports with no recurrence and with favorable outcomes.
神经鞘瘤是良性、孤立、有包膜的肿瘤，可起源于周围神经系统的任何部位，但嗅神经和视神经除外。舌根部神经鞘瘤非常罕见，仅有散发病例的记载。舌根部位对外科医生来说是个挑战。二氧化碳（CO₂）激光可能为此类病变提供一种有效的手术选择，因为它易于接近病变部位、手术视野无血且伤口上皮化良好。
我们报告一例经口二氧化碳辅助切除治疗的带蒂舌根部神经鞘瘤的罕见病例。我们还提供了一份英文的关于人类的现有文献综述。
作者检索了截至2018年7月的PubMed数据库和谷歌。应用了以下检索词：[具体检索词未给出]与[具体检索词未给出]以及[具体检索词未给出]组合。筛选了标题和摘要，然后仅考虑声门上（下咽）舌根部肿物。本综述纳入了14篇文章，报告了17例病例。患者年龄从9岁到39岁不等，主要为女性。吞咽困难和肿块感是最常见的症状，平均随访期为1.5至60个月（平均 = 13个月）。所有病例均无复发迹象。
我们可以得出结论，舌根部神经鞘瘤罕见。经口完整切除肿瘤是首选治疗方法。二氧化碳激光手术是一种微创治疗选择，在少数报告中已实施，无复发且效果良好。
