RESUMO
The platysma myocutaneous flap is rarely reported as an option for reconstruction in the head and neck. In our experience it is a reliable flap that is easy to raise, has a limited risk of morbidity at the donor site, and allows for early recommencement of oral function. We report a patient with an unusually aggressive orocutaneous fistula that complicated the simple extraction of teeth. We modified the platysma flap to provide two independent skin paddles so we could reconstruct both the intraoral and cutaneous defects simultaneously with a good clinical outcome.

We present the design and performance of the Texas Petawatt Laser, which produces a 186 J 167 fs pulse based on the combination of optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass amplification. OPCPA provides the majority of the gain and is used to broaden and shape the seed spectrum, while amplification in Nd:glass accounts for >99% of the final pulse energy. Compression is achieved with highly efficient multilayer dielectric gratings.
