Evaluation of septal perforation size using a novel measuring device

Area of Science:

• Otolaryngology
• Medical Device Development
• Biomedical Engineering

Background:

• Nasal septal perforations impact airflow and require management, often with septal button prostheses.
• Accurate measurement of perforations is crucial for effective prosthesis fitting and patient comfort.
• Current clinical methods for measuring septal perforations can be challenging and inaccurate.

Purpose of the Study:

• To evaluate the accuracy and ease of use of two novel 3D-printed instruments for measuring nasal septal perforations.
• To compare the performance of these new sizers against traditional measurement techniques.

Main Methods:

• Two types of 3D-printed sizers (serial and graded) were developed.
• Nasal septal perforations were created in cadaver heads.
• Otolaryngology professionals measured perforations using eyeball estimation, a ruler, and the novel sizers.
• Accuracy was defined as ±1 mm of the true measurement; statistical analyses included Chi-square and ANOVA.

Main Results:

• The novel sizers demonstrated significantly higher accuracy in measuring perforation length and height compared to eyeball estimation and ruler methods.
• The eyeball method significantly overestimated perforation length and was less accurate than the other methods.
• No correlation was found between participant experience and measurement accuracy.
• Participants showed a clear preference for the novel sizers due to ease of use.

Conclusions:

• The developed 3D-printed sizers are more accurate and user-friendly than traditional methods for measuring nasal septal perforations.
• Wider adoption of these sizers could lead to improved patient outcomes and satisfaction.
• Further study and implementation of these devices are recommended for advancing septal perforation management.
