Endoscopic Temporalis Tendon Extension (ETTE)

Area of Science:

• Plastic Surgery
• Neurosurgery
• Otolaryngology

Background:

• Facial nerve palsy significantly impacts facial symmetry and quality of life.
• Existing surgical techniques for facial symmetry restoration have limitations.

Purpose of the Study:

• To present and evaluate the Endoscopic Temporalis Tendon Extension (ETTE) surgical technique.
• To assess the efficacy of ETTE in restoring facial symmetry in patients with facial nerve palsy.

Main Methods:

• The ETTE procedure involves a nasolabial incision and endoscopic dissection.
• Key steps include masseter muscle detachment, coronoid process sectioning (Piezosurgery®), and fascia lata graft suspension.
• The technique combines static suspension and dynamic muscle contraction components.

Main Results:

• ETTE utilizes the preserved temporalis muscle for optimal contraction.
• A fascia lata graft provides necessary length for the suspension.
• The nasolabial incision aids in recreating the nasolabial fold, enhancing aesthetic results.

Conclusions:

• Endoscopic Temporalis Tendon Extension (ETTE) is an effective surgical approach for facial symmetry restoration.
• The technique offers both static and dynamic components for improved functional and aesthetic outcomes.
• Endoscopic assistance enhances procedural precision and reduces the learning curve for surgeons.
