Nasal septum configuration as a basis for novel septal splints

Area of Science:

• Anatomical studies
• Biomedical engineering
• Otolaryngology

Background:

• Nasal septal splints are crucial for postoperative care following septoplasty and septorhinoplasty.
• Current splints may have limitations in terms of fit, coverage, and even pressure distribution.
• Ensuring adequate mucosal perfusion is vital to prevent complications.

Purpose of the Study:

• To design universal silastic septal splints based on anatomical measurements of nasal septum shape and surface area.
• To develop a secure method for splint fixation that ensures even surface pressure distribution without compromising capillary perfusion.
• To optimize splint design for maximum coverage and ease of insertion.

Main Methods:

• Anatomical determinations of nasal septum shape and surface area in adult Caucasian body donors (n=21).
• Measurement of nasal septum thickness using CT scans (n=20).
• Fabrication of universal silastic septal splints and calculation of holding force and surface pressure exerted by integrated neodymium-iron-boron (NdFeB) magnets.

Main Results:

• Novel silastic septal splints demonstrated a satisfactory fit in clinical practice.
• Integrated NdFeB magnets provided secure attachment and even surface pressure distribution.
• Splints achieved maximum possible septum coverage with simple intranasal insertion.

Conclusions:

• Magnet-secured silastic septal splints offer a universal fit, optimal coverage, and even pressure distribution.
• The design minimizes interference with septal tissue perfusion, potentially leading to fewer postoperative complications.
• These novel splints represent an advancement in postoperative care for septoplasty and septorhinoplasty procedures.
