Sir:

Clinical and surgical photographs are valuable for maxillofacial surgeons. Photographs can help surgeons to review novel procedures performed and can be used to teach students and residents and prepare manuscripts. Taking photographs of the oral cavity requires specialized techniques, because the oral cavity is a narrow, deep, dark space. A conventional single-lens reflex camera with a ring flash can be used to take these photographs, but such cameras are large, heavy, and expensive. A conventional compact digital camera is light and affordable but does not have a suitable focusing distance for taking photographs of the oral cavity. We started using compact digital cameras from the Cyber-shot DSC-T30 and TX series (Sony, Tokyo, Japan) to take clinical, surgical, and experimental photographs in 2008.1–5 We currently use the Cyber-shot DSC-TX30 (96.4 × 59.3 × 15.4 mm, 140 g, 18.2 megapixels, price approximately USD250; Sony) (Fig. 1). This camera is waterproof and shockproof and has passed a drop test from a height of 1.5 m. The camera is used with an exposure value of +0.7 and fill-in flash, and the operating lights turned off. To take photographs during surgical procedures, the surgeon holds the camera in one hand, which is covered by an extra sterile glove over the surgical glove and exposes the operative field with the other hand using a retractor (Fig. 2). The camera automatically focuses on the surgical site. The Cyber-shot DSC-TX30 includes an LED ring flash, which is not useful for taking photographs of the oral cavity, but it is useful for taking photographs of surgical specimens from as little as 10 mm away, without causing shadows. No another settings are necessary for taking photographs. This camera can also record approximately 30 minutes of full high-definition video (1920 × 1080 pixels, video format: AVCHD). Surgeons can record a clear surgical video using only one hand, because the camera includes an image stabilization system.

We were able to take clear surgical photographs of the face and neck, mandible,1 maxilla,2 zygoma, orbit, hard palate, tongue, buccal mucosa,3 floor of the mouth, nasal septum, hypoglossal nerve, and facial nerve using the Cyber-shot camera. Use of this camera may reduce interruptions during surgery compared with use of a conventional single-lens reflex camera with a ring flash. We believe that clear photographs are best taken by the surgeon rather than by observers or residents.
