An electromyographic examination of lip asymmetry during speech and non-speech oral movements in adults who stutterChoo, Ai Leen January 2008 (has links)
Past research investigating stuttering has cited atypical cerebral lateralization in adults who stutter (AWS) during speech production. The purpose of this study was to measure cerebral activation in AWS as indicated by lip asymmetry. The study included five AWS (mean age = 26 years of age) and five adults who do not stutter (AWNS) (mean age = 25 years of age). The tasks included single-word productions, single-sentence readings and lip pursings. The peak electromyographic (EMG) amplitude was determined for the left upper, right upper, left lower and right lower lip quadrants around the mouth. Overall, EMG amplitudes were higher for the lower lip than the upper lip. Based on examination of peak EMG amplitude, significant differences were found between speaker groups. For both speech and non-speech tasks, the highest EMG amplitude for the AWS and AWNS groups were on the left lower and right lower sides of the mouth, respectively. The AWNS group showed strong correlations in EMG activity across the four lip sites (r>0.97), indicating an overall synchronous lip activity during speech and non-speech tasks. In contrast, the AWS group showed a strong correlation (r=0.97) only for the left upper and left lower lips while the other lip pairings were not strongly correlated (r<0.738) indicating otherwise reduced synchronous lip activity. While the small sample size suggests caution, clear differences in the pattern of lip EMG activity demonstrated in the present study provides evidence of differences between AWS and AWNS in the cerebral activation governing lip movement. The greater left lip activity observed in AWS was indicative of greater right hemisphere cerebral activation while increased right lip activity was indicative of greater left hemisphere participation in AWNS. The results of the present study provided support for the hypotheses of reversed lateralization for speech and non-speech processing and reduced coordination of speech musculature in AWS.

Evaluation of unilateral cleft lip repairs and the evolution of a new technique based on experience and researchChristofides, Efthimios Andreas 14 April 2011 (has links)
MSc, Plastic and Reconstructive Surgery, Faculty of Health Sciences, University of the Witwatersrand / Evolution of cleft lip repair has been ongoing for many years.
The reason for the various techniques stems from the advances
relevant to function and aesthetics of the repair.
Unfortunately, the literature does not reveal the long term
results of many of these procedures with reference to normal
lip anthropometrics. The reason for this is that the normal lip
anthropometrics have not been adequately described. This study
aims to describe a new technique for unilateral cleft lip
repair and to substantiate its evolution by comparing it to the
normal upper lips as well as to the most popular current
technique of cleft lip repair (Millard technique). This will
be done by the following steps:
1. Evaluate the most commonly used current technique of
unilateral cleft lip repair (Millard rotation
advancement), both objectively and subjectively.
2. Assess the normal anthropometric measurements of the
horizontal lip dimensions.
a. To assess normal horizontal lip dimensions according to
different age categories to serve as reference values
for further studies.
b. To assess the timing where the lip is fully developed.
vi
c. To assess Cupid’s bow length in relation to horizontal
lip length at different ages, thereby assessing dynamic
changes with growth.
3. Compare the currently used technique of unilateral cleft
lip repair to normal values indicating the anatomical
drawbacks to the technique.
4. Describe a new technique for unilateral cleft lip repair
which eliminates some of the unwanted drawbacks of the
Millard technique.
This new technique has the distinct advantage of maintaining
better lip symmetry and not breaching anatomical landmarks of
the lip. This technique is referred to as the straight line
repair and is easy to teach and the results are reproducible

Intercenter Comparison of Treatment Outcome in Patients with Complete Unilateral and Bilateral Cleft Lip and Palate: Analysis of Craniofacial FormDugas, Gregory 13 January 2010 (has links)
Background: Several treatment protocols exist for the management of patients with complete unilateral (CUCLP) and bilateral (CBCLP) cleft lip and palate, and little evidence exists on comparison of their outcomes. Objectives: To compare craniofacial morphology among individuals with CUCLP and CBCLP treated at different North American centers. Methods: Lateral cephalograms of 148 individuals with repaired CUCLP (average age = 8y 8m) and 93 individuals with repaired CBCLP (average age = 8y 10m) were analyzed. The group means for the different centers per cephalometric measurement evaluated (16 angular, 7 linear, and 2 ratio), were compared using ANOVA. Results: For both the CUCLP and CBCLP samples, the most significant differences were observed in the sagittal maxillary prominence. The center that performed primary alveolar bone grafting consistently showed the lowest maxillary prominence. Conclusions: Significant differences in craniofacial morphology, specifically maxillary prominence, exist among patients with CUCLP and CBCLP treated at different North American centers.
