Preexpansion scoring releases the inflexible galea, permitting more rapid expansion of the scalp. In addition, when comparing this procedure with conventional scalp expansion, patients reported less pain when the galea was incised prior to insertion of the tissue expanders.
Since modern tissue expansion was introduced in 1976, it has proved to be a safe and effective technique for obtaining extra tissue where traditionally distant flaps and grafts had been used. However, the lengthy expansion times and prolonged gross deformity of conventional expansion protocols have often deterred both physician and patient from choosing this reconstructive option. Over the past decade, attempts to shorten the total expansion time have centered around decreasing the time intervals between injections. Recently, researchers at Washington University have developed the technique of continuous tissue expansion (CTE), using a custom-designed, computerized pump. With CTE, expansion times have been shortened from 2 weeks to 3 days. At our institution, we have demonstrated that CTE can be safely and economically performed with the use of equipment already existent in most medical centers. We describe the equipment and technique and present two cases of successful clinical application of CTE.

Carpal tunnel compression syndrome caused by a retracted divided sublimus tendon has been presented. The case presented here represents another cause of carpal tunnel compression syndrome. With resection of the space-occupying retracted and scarred sublimis tendon, the symptoms of median nerve compression remitted. Considering the large volume of hand surgery done annually, it is surprising that this particular cause of carpal tunnel compression syndrome has not been reported previously.
