Purpose:

Markings for planning incisions in reconstructive surgery are commonly drawn free-hand and to the surgeon’s best estimate, leading to potential mistakes that can lead to increased procedure time and patient risk. A previous study performed by our group has shown that flap marking can be improved by designing accurate flaps on google SketchUp and projecting the image as a stencil onto a patient using a handheld projector. The purpose of manuscript is to introduce a new surgical planning mobile application developed by our group that allows for surgeons to select, modify and personalize a database of local flaps. These flaps can then be projected onto a patient requiring reconstruction to offer a more accurate and personalized flap design.

Material and Methods:

A mobile application was developed with a variety of flaps including but not limited to Rhomboid, Bilobed, Z-plasty, W-plasty, and nipple reconstruction markings. Using the mobile interface, photographs of areas requiring reconstruction were taken and uploaded onto the device. The application was then used to superimpose a flap and modify it to best fit the area requiring reconstruction in the photograph. The personalized and accurate flap was then projected using a wireless projector onto the patient. Projected flaps were then analyzed and compared based on expected geometric parameters.

Data:

Using the mobile application accurate and personalized flaps were created for Rhomboid, Bilobed, Z-plasty, W-plasty, and nipple reconstruction. All flaps served as accurate stencils with 0% deviation in each angles and limb measured.

Summary of Results:

Using our mobile application flap can be designed and projected onto an area requiring reconstruction with 0% deviation from expected measurements. 

Conclusion:

We have developed a surgical planning mobile application for reconstructive surgeons that allows for selection, modification and personalization of a database of local flaps. These flaps can then be projected wirelessly onto a patient’s defect requiring reconstruction serving as an accurate stencil.
