A 5 minute double chin guide for injectors

Time needed: 15 minutes.

How to perform double chin injections – a guide for practitioners

  1. Clean away make-up

  2. Mark the treatment area using a make-up pencil

    The lateral border should be no more lateral than the sternocleidomastoid muscle. Inferiorly inject no lower than the hyoid bone. Mark out the jawline and then a second parallel line 1.5cm below the jawline.

  3. Draw a perpendicular line from chin downwards using a make-up pencil

  4. Draw a horizontal line on the skin using a mark-up pencil to indicate the position of the hyoid bone

  5. Peel plastic backing off double chin grid

  6. Line up the black middle dots with your perpendicular line and press the double chin marking grid onto the skin

  7. Press wet gauze against grid to wet

  8. Apply pressure to the grid to help the dots stick

  9. Remove the grid gently – marking dots will be left on the skin

  10. Remove dots outside the treatment area with an alcohol wipe

  11. Draw up 2% lignocaine into a sterile 3ml syringe

  12. Attach long 25g needle to 3ml syringe

  13. Lift patient’s chin

  14. Introduce needle lateral to the most infero-lateral dot in the submental area

  15. Advance needle then perform retrograde injection of local anaesthetic

  16. Infiltrate local into the treatment area

    Tip: Tilt the patient’s head away to infiltrate the most lateral area – it makes it easier to inject that area

  17. Draw up the double chin vial into 3ml syrgine containing 0.5ml lignocaine

  18. Attach a 30g needle to the 3ml syringe and remove dead air space

  19. Clean treatment area with chlorhexidine and alcohol twice

  20. Lift patient chin and inject 8mm deep into each dot

    Tip: Treat in vertical columns to make it easier to remember which dots have been treated

  21. When you have finished treating apply pressure under the chin using gauze

    Tip: Ask the patient to press on the gauze with their thumbs whilst you write your notes. When you have finished your notes ask the patient to stop pressing and the area should have stopped bleeding.

Additional tips

– Your needle should be bevel up when injecting local
– Always inject local anaesthetic in a retrograde manner
– Use an entry point lateral to the most lateral dot when giving local anaesthetic
