Area of Science:

  • Oral and Maxillofacial Surgery
  • Plastic Surgery
  • Reconstructive Surgery

Background:

  • The lip is vital for speech, swallowing, chewing, and facial expression.
  • Lip defects present complex reconstructive challenges due to intricate anatomy and function.
  • Restoring lip integrity is crucial for physiological and aesthetic outcomes.

Purpose of the Study:

  • To review current methods for functional restoration and reconstruction of lip defects.
  • To highlight the use of local flaps incorporating the depressor anguli oris muscle.
  • To discuss strategies for extensive oral and maxillofacial defects with associated lip involvement.

Main Methods:

  • Review of surgical techniques for lip defect reconstruction.
  • Analysis of local flaps, including those with depressor anguli oris muscle.
  • Evaluation of free flap applications in lip reconstruction.
  • Assessment of combined tissue flap approaches for extensive defects.

Main Results:

  • Local flaps with depressor anguli oris muscle offer viable options for lip reconstruction.
  • Free flaps provide alternatives for specific or complex lip defect scenarios.
  • Combined tissue flap techniques enable repair of extensive maxillofacial defects involving the lip.

Conclusions:

  • Various flap techniques, including local and free flaps, are effective for lip reconstruction.
  • Tailored approaches using combined flaps are essential for extensive defects.
  • Successful lip reconstruction requires careful consideration of anatomy, defect type, and functional restoration.
