Mucoceles are cystic diseases of the oral mucosa. The most common are ranula and mococeles of the lower lip. Blandin and Nuhn mucoceles, which develop at the ventral side of the tongue, are rare benign lesions. They are often misdiagnosed and sometimes confused with ranula. The recommended treatment is a complete surgical excision of the gland.
We describe 5 clinical cases managed in service between 2009 and 2016. Clinical cases are presented in order to detail their clinical history, paraclinical and treatment.
The clinical appearance is a longitudinal swelling of the ventral surface of the tongue, parallel to the frenulum. The volume of the swelling is variable; it is normally around 30 × 10 mm. The paraclinical (ultrasound, CT, MRI, or ponction) could be performed. CT showed an cyst located on the ventral surface of the tongue, with liquid density. Blandin and Nunh mucocele were strictly anechogenic. MRI confirms the liquid content of this cyst (low T1signal, high T2signal and no post-contrast-enhanced). The resection of Blandin and Nuhn glands should respect the sublingual gland, the lingual nerve and the lingual veins in the mouth floor.
This study demonstrates that Blandin and Nuhn mucoceles must be understood and recognised to propose complete excision of the Blandin and Nuhn gland and avoid recurrence.
黏液囊肿是口腔黏膜的囊性疾病。最常见的是舌下腺囊肿和下唇黏液囊肿。 Blandin 和 Nuhn 黏液囊肿发生在舌腹侧，是罕见的良性病变。它们经常被误诊，有时与舌下腺囊肿混淆。推荐的治疗方法是完整切除腺体。
我们描述了 2009 年至 2016 年期间在该科室管理的 5 例临床病例。为了详细介绍其临床病史、辅助检查和治疗，我们按顺序介绍了这些临床病例。
临床表现为舌腹侧的纵向肿胀，与舌系带平行。肿胀的体积是可变的，通常约为 30×10mm。可进行辅助检查（超声、CT、MRI 或穿刺）。CT 显示位于舌腹侧的囊肿，呈液体密度。Blandin 和 Nunh 黏液囊肿均为严格无回声。MRI 证实了该囊肿的液体含量（低 T1 信号、高 T2 信号且无增强后强化）。Blandin 和 Nuhn 腺体的切除应注意保护舌下腺、舌神经和口底舌静脉。
本研究表明，必须理解和认识 Blandin 和 Nuhn 黏液囊肿，以便提出完整切除 Blandin 和 Nuhn 腺体并避免复发。
