Background: Intranasal splints are medical devices used after nasal surgeries (like septoplasty and rhinoplasty) to stabilize the nasal structures, maintain airway patency, prevent tissue adhesion, and support healing. Typically made from flexible materials like silicone, they help reduce discomfort and support the recovery process. Intranasal splints are widely used in post-operative nasal surgeries such as septoplasty, rhinoplasty, and nasal fracture repairs to maintain nasal airway patency, prevent tissue adhesion, and support efficient healing. These splints, often composed of medical-grade silicone, are designed to stabilize the septum while minimizing patient discomfort and nasal obstruction. Objective: This study aims to evaluate the ease of insertion, structural integrity, and airway support of different nasal splint designs—Bi-Valve, Airway, and Pre-Cut—through an in-vitro simulation using a physical nasal model.
Methods: A simulated nasal environment was developed to assess the insertion mechanics, stability, and airflow properties of the splints under conditions mimicking post-surgical healing. The splints were evaluated for their ability to maintain airway patency, prevent posterior dislodgement, and minimize insertion-related stress. Performance parameters such as positioning accuracy and airflow resistance were analyzed to predict their viability.
Results: The findings indicate that all three splint designs exhibit excellent flexibility and stability while ensuring minimal airway obstruction. The Bi-Valve splint demonstrated superior adaptability to nasal contours, whereas the Airway and Pre-Cut splints provided enhanced airflow due to their integrated airway tubes. Additionally, the presence of suture indicators facilitated secure fixation, reducing the risk of posterior displacement.
Conclusion: This study underscores the critical role of intranasal splints in post-surgical nasal recovery and highlights their design considerations for optimal clinical outcomes. The in-vitro simulations validate the effectiveness of these splints in maintaining airway patency and ensuring patient comfort, providing valuable insights for further refinement and clinical implementation.
