[Bypass whartonostomy (author's transl)].

Submaxillary salivary retention, associated with the typical sign of a painful swelling, is usually but not specifically due to the presence of stones. Other factors may indeed be involved (reflex secretory dysfunction, stenosis from a scar, inflammation or tumor of wharton's duct). The authors describe a technique, employed in 14 patients, which involves a permanent bypass of "salivary flow" by the creation of a new excretory orifice in wharton's duct proximal to the obstacle producing salivary stasis. This technique is used as a complement to treatment of the cause of salivary retention, and appears to improve long-term results especially in some types of disorders due to submaxillary stones.

[Sialography of the submaxillary glands. A technique for catheterization of Wharton's duct (author's transl)].

Except in cases where stones are present, it is often difficult to catheterize Wharton's duct through the opening when conducting sialography of the submaxillary glands. When direct catheterization is impossible the authors perform indirect catheterization proximal to the opening by turning back a periorificial mucous flap, posteriorly concave, after exposing the canal.

Type and hold system for better blood utilization.

Blood bank personnel can convince surgeons to change their presurgical blood orders from a type-and-crossmatch to a type-and-hold approach. To do this, it is necessary to guarantee blood availability within a short time frame if blood should be unexpectedly required. Such a change in blood orders significantly reduced the number of unnecessary crossmatches and the amount of wasted outdated blood in our institution. Economic savings and conservation of resources were realized without compromising the patients' safety or the quality of our service.
