“Objective: To compare the skeletal features of subjects with adenoid hypertrophy with those of children with tonsillar hypertrophy using thin-plate spline (TPS) analysis.
Materials and methods: A group of 20 subjects (9 girls and 11 boys; mean age 8.4 +/- 0.9 years) with adenoid hypertrophy (AG) was compared with a group of 20 subjects (10 girls and 10 boys; mean age 8.2 +/- 1.1 years) with tonsillar hypertrophy (TG). Craniofacial morphology was analyzed on the lateral cephalograms of the subjects in both groups by means of TPS analysis. A cross-sectional comparison was performed on both size and shape differences between the two groups.
Results: AG exhibited statistically significant shape and size differences in craniofacial see more configuration with respect to TG. Subjects with adenoid hypertrophy showed an upward dislocation of the anterior region of the maxilla, a more downward/backward position of the anterior region of the mandibular body and an upward/backward displacement of the condylar region. Conversely, subjects with tonsillar
hypertrophy showed a downward dislocation of the anterior region of the maxilla, a more upward/forward position of the anterior region of the mandibular body and a downward/forward displacement of the condylar region.
Conclusions: Subjects with adenoid hypertrophy exhibited features suggesting a more retrognathic mandible while subjects with tonsillar hypertrophy showed BIIB057 order features suggesting a more prognathic mandible. (C) Wortmannin cost 2011 Elsevier Ireland Ltd. All rights reserved.”
“The Parker Flex-Tip(A (R)) tube, in combination with the Pentax-Airwayscope(A (R)) (AWS), is anecdotally
reported to facilitate intubation when the AWS tip fails to be inserted behind the epiglottis. We examined whether the Parker tube facilitates intubation when the AWS tip is inserted into the vallecula. Forty patients were randomly assigned into either the standard or Parker tube group. Following general anesthesia induction, AWS intubation was attempted with the blade tip inserted into the vallecula. After obtaining an optimal laryngeal view, the tube was advanced toward the glottis. The laryngoscopist allowed additional adjustment of the blade tip direction when the first tube insertion failed because of involvement or folding of the epiglottis resulting from advancement of the tube. The primary outcome was defined as the success rate for intubation and secondary outcome as the time needed for tube placement. The Parker tube provided both a higher intubation success rate (17/20 vs. 4/20, P < 0.01), and a faster intubation time (17 +/- A 5 s vs. 25 +/- A 4 s, P < 0.
