Septoplasty retards midfacial growth in a rabbit model

Area of Science:

• Otolaryngology
• Pediatric surgery
• Craniofacial biology

Background:

• Septoplasty in children is debated due to potential midfacial growth interference.
• Concerns exist regarding the impact of surgical cartilage removal on facial development.

Purpose of the Study:

• To investigate if septoplasty in prepubertal rabbits causes midfacial growth retardation.
• To determine if porous polyethylene implants can prevent growth deficits after septoplasty.

Main Methods:

• A prospective, controlled animal study using a rabbit snout model.
• Sixteen young rabbits underwent conservative septoplasty; some received porous polyethylene grafts, others did not.
• Cephalometric analysis of radiographs was used to measure midfacial growth.

Main Results:

• Septoplasty resulted in significant midfacial growth disturbances compared to controls.
• No significant differences in growth were observed between the two experimental groups (graft vs. no graft).

Conclusions:

• Conservative septoplasty in young rabbits leads to midfacial growth retardation.
• Porous polyethylene implants do not prevent this growth retardation, supporting concerns from human studies.
