Primary alveolar cleft bone grafting in unilateral cleft lip and palate: arch dimensions at age 8.

The purpose of this investigation is to determine whether primary alveolar cleft bone grafting in infants with unilateral cleft lip and palate (N = 17) leads to less favorable dental arch dimensions at age 8 when compared with other 8-year-old patients with unilateral cleft lip and palate who received no alveolar bone grafting procedures (N = 49). Dental casts were obtained for the primary grafted group, and arch lengths and widths were digitally recorded with a reflex microscope. These arch dimensions were then compared with the reported data for a nongrafted group and a noncleft group of 8-year-old children. The major findings were: 1) that the dental arches of both cleft groups generally demonstrated a significant diminution in length and width (P < 0.05) compared with the noncleft groups, and 2) that the patients who underwent primary alveolar cleft bone grafting showed no statistically significant difference for any arch dimension (P < 0.05) when compared with the nongrafted group lacking this additional surgical procedure.

Commissure stabilization appliance in facial reanimation surgery.

A modified maxillary appliance is described that provides an inexpensive intraoral method of commissure stabilization which effectively prevents transmission of stretching forces onto the delicate anastomoses and muscle insertion at the commissure and upper lip in the immediate and early postoperative period. It is well tolerated by the patient, does not interfere with eating, and may be carefully removed for periodic cleaning. It is a simple technique that adds an increased measure of flap security without any risk of morbidity.

The clinical effects of a mouthrinse containing 0.1% octenidine.

The purpose of this three-month clinical trial was to evaluate the effects of a 0.1% octenidine mouthrinse on plaque, gingivitis, extrinsic dental stain, and the oral soft tissues. A total of 451 adult volunteer subjects was initiated into the study and given baseline dental examinations. The subjects were stratified into two balanced groups according to gender, plaque, and gingivitis scores. The subjects then received a dental prophylaxis and were provided with dentifrice, toothbrushes, and either a mouthrinse containing 0.1% octenidine dihydrochloride as the active ingredient or a similar placebo mouthrinse. Subjects were instructed to rinse with their assigned product for 30 s twice each day. Examinations were repeated at six weeks (soft-tissue assessment, gingivitis) and three months (soft tissues, plaque, gingivitis, dental stain). The results showed that the group rinsing with 0.1% octenidine had significantly less plaque (39%), gingivitis (50%), and bleeding sites (60%) than the group using the control product, but had significantly higher stain formation and experienced longer prophylaxis times to remove the stain. The oral soft-tissue examinations revealed no differences in the groups in either the numbers or types of lesions noted.

Facial flushing in children: a variant of the auriculo-temporal syndrome.

Duphenix in 1757 has been credited with describing the first case of gustatory sweating which occurred after drainage of a parotid abscess. Later, Baillarger reported a case in which the sweating occurred on both sides because of bilateral parotitis. In 1923, Frey reported a case of gustatory sweating caused by an infected bullet wound of the parotid. She noted that the sweating coincided with the skin distribution of the auriculo-temporal nerve. Since her report, gustatory sweating has also been known as the "Auriculo-temporal Syndrome" or "Frey's Syndrome."
