Temporalis myocutaneous flap reconstruction of orbital defects may cause difficulty with fabrication of esthetic orbital prostheses because of limited space. Two patient treatments are presented to show the wide variation in defect size that may be encountered after surgical reconstruction. Methods for using optics and illusions to enhance the esthetic result are also presented.

A technique is presented for the fabrication of a custom silicone speech valve retainer that is easily fabricated, may be tinted to match the skin tone, is well tolerated, noninvasive, and functions well in patients who can generate sufficient air pressure to close the valve. This device can greatly improve the quality of life for laryngectomees by allowing hands-free, alaryngeal oral speech.
Numerous remarkable advancements have been made in the area of voice prosthetics. A significant, persistent problem, however, has been the development of air leaks around the tracheostome housing. This problem is particularly apparent with patients having deeply recessed, irregular stomas. This paper describes a customized tracheostome valve housing that is fabricated to minimize or alleviate difficulties associated with maintenance of an airtight seal. Our experience with 12 patients revealed that they maintain adequate seals for 72 hours and enjoy the functional benefits provided by the customized housing.
