  4. Signs
    1. Benign lesion 1-2 cm diameter
    2. Round, regular, translucent or bluish Nodule
    3. Distribution
      1. Typically occurs on inside of lower lip
      2. May occur in any oral surface with Salivary Glands

        1. Shave the lesion with scalpel, removing the top 50-75% but leaving the base
        2. Obtain hemostasis
      4. Technique 2
        1. Place 4-0 or 5-0 Nylon Suture through the Mucocele, creating 2 holes in its surface
        2. Tie the Suture and remove in 5-7 days
      5. Other techniques
        1. Cryotherapy
        2. Electrocautery
