Management of the flap tracheostomy. An experimental study

Area of Science:

• Veterinary Surgery
• Surgical Techniques
• Animal Research

Background:

• Flap tracheostomy is a surgical procedure requiring optimal management strategies.
• Understanding post-decannulation flap behavior is crucial for patient outcomes.
• Canine models offer valuable insights into surgical wound healing.

Purpose of the Study:

• To evaluate different management techniques for flap tracheostomy in adult canines.
• To compare epidermal closure time and soft tissue fixation based on flap management.
• To assess the impact of flap management on tracheal anatomy and cartilage viability.

Main Methods:

• Flap tracheostomies were performed using an inverted U flap incision in 25 adult canines.
• Post-decannulation, flaps were either resewn, dissected, or left in situ.
• Epidermal closure time, soft tissue fixation, and histologic changes were analyzed.

Main Results:

• Resewing or releasing the tracheal flap resulted in more rapid epidermal closure.
• Less soft tissue fixation was observed in the resewn or released flap groups.
• All groups maintained tracheal diameter; resewing promoted smoother tracheal contouring.

Conclusions:

• Resuturing or releasing the tracheal flap enhances healing and reduces complications.
• Flap tracheostomy management impacts wound healing dynamics and anatomical outcomes.
• This animal study provides evidence supporting specific flap tracheostomy management protocols.
