Palato-pharyngeal cine photography: a technique for developing continuing education films

Area of Science:

• Medical Photography
• Surgical Education
• Otolaryngology

Background:

• Effective teaching of plastic and reconstructive surgery, particularly for cleft palate repair and pharyngeal flaps, has been limited by the lack of high-quality, color teaching films.
• The intricate nature of oral and pharyngeal surgeries necessitates close-range work, often creating obstructions and challenging photographic angles.

Purpose of the Study:

• To develop an innovative Cine photography method for recording plastic and reconstructive surgical procedures in the oral cavity and pharynx.
• To overcome the limitations of traditional filming techniques in capturing delicate surgical maneuvers for educational purposes.

Main Methods:

• A head-mounted Cine camera system was designed, utilizing a parallelogram of beam-splitting mirrors to achieve a "through the surgeon's eye" viewpoint.
• An elaborate counter-balancing system was integrated to ensure the camera, mirror, and light complex felt weightless to the surgeon, mounted on a football helmet.
• The system allowed surgeons to operate and simultaneously record their procedures, composing their own surgical films.

Main Results:

• The developed photographic method successfully captured a variety of oral cavity and pharyngeal surgical procedures in color.
• The "through the surgeon's eye" view provided an unparalleled perspective, superior to that of a surgical assistant, for educational purposes.
• The head-mounted system minimized shadows and allowed for continuous recording despite the surgeon's movements.

Conclusions:

• This head-mounted Cine camera system offers a superior method for documenting surgical techniques in plastic and reconstructive surgery of the oral cavity and pharynx.
• The "through the surgeon's eye" filming approach significantly enhances the quality and effectiveness of surgical education for complex procedures.
• The innovative system addresses the challenges of filming delicate surgeries, providing an immersive and highly informative visual record.
