DIAMOND TECHNIQUEDIAMOND TECHNIQUE
Using two hemostats, secure the frenum adjacent to the gingiva and adjacent to the vestibule
Cut on the outside of the hemostats to avoid leaving crushed tissue in place
The key to healing is to open up the submucosal tissue
If you close the wound in its present state, a scar will form, and you will lose what you have attempted to accomplish
Undermine the wound to prevent scar formation
This will ensure a tension-free wound

Surgical release of Surgical release of lingual frenum requires lingual frenum requires dividing the attachment dividing the attachment of fibrous connective of fibrous connective tissue at the base of the tissue at the base of the tongue in a transverse tongue in a transverse fashion, followed by a fashion, followed by a closure in a linear closure in a linear dissection, which dissection, which completely releases the completely releases the ventral aspect of ventral aspect of tongue from alveolar tongue from alveolar mucosamucosa..
Electrocautery or Electrocautery or hemostat is used to hemostat is used to control bleeding and for control bleeding and for visibility. visibility.
