A 3D printed smartphone adaptor for nasolaryngoscopy.

Objective: The objective of this project is to create a three-dimensional (3D) printed smartphone adaptor for flexible nasolaryngoscopy (FNL) to provide an affordable alternative to commercial options and a better fit than generic telescope phone adaptors.

Method: We designed an adaptor using computer aided software to connect an iPhone XS to an Olympus Rhino-Laryngo Fibre Scope. We experimented with various 3D printing materials and iterative designs to create a case that allowed for quality recording of a nasolaryngoscope exam using the iPhone's built in ×2 telescopic zoom lens.
