A Fatty Flap Taken From the Double Chin for Chin Enhancement: a New Surgical Technique

The double chin is a troublesome component of the lower third of the face. It gives an embarrassing and unpleasant facial appearance to both men and women leading them to ask for liposuction. Moreover, a "receding chin" causes blunting of the cervico-mental angle, a fleshy appearing neck, a disproportion in the profile line of the face with a prominent looking nose, and an irregular mandibular border. This study is about an innovative surgical procedure: Instead of doing liposuction of the double chin, the investigators used the fat of this area as a flap to improve a "receding chin". hence both the double chin and the receding chin are treated.

About this study

the surgical technique was performed on 10 participants. written informed consent was obtained from all the participants.

Description of the surgical technique:

The investigators began by delineating the undesirable subplatysmal fat located in the submental region, just below the subcutaneous fat. The skin redundancy assessed by the pinch test was excised. Under general anesthesia, an incision was made behind the submental crease followed by the excision of the skin excess. The subplatysmal fatty compartment was individualized through a subcutaneous dissection. Then, the lower part of the subplatysmal fat was cut to start its separation from the platysma muscle, thus obtaining a real vascularized fatty flap. This flap could be folded on itself, then easily turned over to be fixed on the thin layer of the pre-muscular fat overlying the chin. Hemostasis was performed correctly avoiding the establishment of drainage.

chin projection and submental rejuvenation were obtained. The advancement of the chin ranged from 3,5 to 12 millimeters. The stability of the translated fat was observed after surgery for more than two years.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • the presence of a "double chin" with slightly redundant skin and a "receding chin" causing a fleshy appearing neck, and a disproportion in the face profile

Exclusion criteria

  • any history of a precedent surgery on the neck, the presence of a traumatic or a burn scar on the cervical region.

Treatment and study plan

chin enhancement with a fatty flap sculpted from the double chin

Procedure

Under general anesthesia, an incision was made behind the submental crease followed by the excision of the skin excess. The preplatysmal fatty compartment was individualized through a subcutaneous dissection. Then, the lower part of the preplatysmal fat was cut to start its separation from the platysma muscle, thus obtaining a real vascularized fatty flap. This flap could be folded on itself, then easily turned over to be fixed on the muscular layer of the chin.

Other names: submental fatty flap treating the double chin and correcting the micrognathia

Primary outcomes

  1. Chin advancement measure

    Time frame: The change of chin projection at 6 months after the surgical procedure

    For the objective evaluation: Chin advancement was evaluated by measuring, with a Vernier caliper, the distance between the submental crease and the soft tissue at the pogonion. This distance was taken before and after the surgical procedure. The advancement of the chin ranged from 3,5 to 12 millimeters (mm). This measurement was taken by the investigator during the follow-up appointments. For the subjective evaluation: The results were evaluated on patient reviews and photographic studies (before and after surgery).

  2. Chin advancement measure

    Time frame: The change of chin projection at 12 months after the surgical procedure

    For the objective evaluation: Chin advancement was evaluated by measuring, with a Vernier caliper, the distance between the submental crease and the soft tissue at the pogonion. This distance was taken before and after the surgical procedure. The advancement of the chin ranged from 3,5 to 12 millimeters (mm). This measurement was taken by the investigator during the follow-up appointments. For the subjective evaluation: The results were evaluated on patient reviews and photographic studies (before and after surgery).

  3. Chin advancement measure assessing the stability of the result

    Time frame: The change of chin projection at 24 months after the surgical procedure

    For the objective evaluation: Chin advancement was evaluated by measuring, with a Vernier caliper, the distance between the submental crease and the soft tissue at the pogonion. This distance was taken before and after the surgical procedure. The advancement of the chin ranged from 3,5 to 12 millimeters (mm). This measurement was taken by the investigator during the follow-up appointments. For the subjective evaluation: The results were evaluated on patient reviews and photographic studies (before and after surgery).

  4. Fat deposits removal in the submental region

    Time frame: At 6 months after the surgical procedure

    This outcome was evaluated on photos (face and profile) before and after surgery. A questionnaire including three levels of satisfaction (not satisfied, satisfied, very satisfied) was completed by the participants concerning the surgical outcomes including the submental change and the chin advancement.

  5. Fat deposits removal in the submental region

    Time frame: At 12 months after the surgical procedure

    This outcome was evaluated on photos (face and profile) before and after surgery. A questionnaire including three levels of satisfaction (not satisfied, satisfied, very satisfied) was completed by the participants concerning the surgical outcomes including the submental change and the chin advancement.

Secondary outcomes

  1. The evaluation of the surgical scar

    Time frame: At 6 months after the surgical procedure

    The aspect of the scar was evaluated by the investigator by two parameters: the pigmentation (normal colored, hypopigmentation, hyperpigmentation) and the throphycity (hypertrophic, depressive, adequate trophicity).

  2. The evaluation of the surgical scar

    Time frame: At 12 months after the surgical procedure

    The aspect of the scar was evaluated by the investigator by two parameters: the pigmentation (normal colored, hypopigmentation, hyperpigmentation) and the throphycity (hypertrophic, depressive, adequate trophicity).
