Nasal Tip Projection and Nasolabial Angle Measurement in Open Rhinoplasty
The Davis Nasal Projectometer is a nasal measuring instrument in the Measuring & Marking Instruments category, designed by Richard Davis, MD and manufactured by BusinessMed Instruments®. It is indicated for use in Plastic Surgery, ENT (Otorhinolaryngology), and Rhinoplasty.
The Davis Nasal Projectometer measures nasal tip projection, radix height, rhinion position, and nasolabial angle across the osseocartilaginous nasal vault and anterior nasal spine during open rhinoplasty, in the post-skin-soft-tissue-envelope-elevation measurement phase.
Dual-Axis Independent X-Y Calibration
The Dual-Axis Independent X-Y Calibration system separates horizontal tip projection measurement and vertical dorsal height measurement into independent metric scales within a single instrument placement. The Dental Stop seats on the maxillary alveolar crest to establish the zero-reference baseline. The Notched Forehead Base constrains midline alignment. User-Friendly Independent Thumb Screw Calibration locks each axis independently after registration, preventing pin drift.
Tilting Nasolabial Pin and Sliding Tip-Defining Pin
The Tilting Nasolabial Pin rotates through a 0°–130° arc at the columellar-labial junction to read the nasolabial angle on an angular scale. This rotational mechanism is physically independent of the Sliding Tip-Defining Pin, which translates linearly along the X-axis on a 0–70 mm metric scale to record tip projection distance from the zero-reference baseline. Three Removable Customization Pins allow substitution of the working-end pins to accommodate patient-specific anatomical variation and alternate measurement reference configurations.
Intraoperative Projection Data and Pollybeak Deformity Prevention
The Davis Nasal Projectometer produces surface-only contact at the maxillary alveolar crest and pronatale — no tissue cutting, penetration, or structural deformation occurs at clinical measurement pressure. This contact profile enables the Davis Nasal Projectometer to deliver four-point metric data against the Goode method benchmark (tip projection equal to approximately 0.55–0.60 of nasal length), supporting objective prevention of pollybeak deformity.
Technical Specifications
Clinical Uses and Applications
- Nasal tip projection at the pronatale is measured in open rhinoplasty to determine the exact quantity of dorsal reduction required.
- The osseocartilaginous nasal vault is referenced intraoperatively in rhinoplasty to establish radix height and rhinion position across the dorsal profile.
- The nasolabial angle is assessed at the columellar-labial junction in open rhinoplasty to quantify nasal rotation and plan caudal septal modification.
- The anterior nasal spine is contacted via the Dental Stop in open rhinoplasty to establish the zero-reference baseline for all four measurement points.
- The skin-soft tissue envelope is referenced at the pronatale in open rhinoplasty after SSTE elevation to register the tip-defining point against the baseline.
- The supratip break is evaluated intraoperatively in rhinoplasty to confirm intended dorsal aesthetic relative to the tip-defining points.
- The alar-columellar relationship is assessed during open rhinoplasty to correlate tip projection data with columellar show and rotational outcome.
- Nasal tip projection and nasolabial angle are measured in ENT-performed rhinoplasty procedures to quantify projection and rotation against sex- and ethnicity-specific norms.
