Craniomaxillofacial deformities/cosmetic surgeryImprovement in Respiration and Craniofacial Changes Associated With Weight Loss After Bariatric Surgery
Section snippets
Materials and Methods
This study was carried out at the outpatient clinic of the Division of General Surgery and Obesity Surgery of the University Hospital of the Federal University of Pernambuco in association with the Department of Oral and Maxillofacial Surgery of the University of Pernambuco (Brazil). In 2008 and 2009, 2 groups were studied and evaluated with regard to craniofacial characteristics, as well as quality of sleep and nasal respiration.
The obese group (OG) was made up of 17 patients with severe
Results
None of the subjects exhibited important facial asymmetries. There was a predominance of a type I facial profile and brachycephalic characteristic (Table 1).
Table 2 shows significant differences between groups and evaluation times with regard to weight, BMI, neck circumference, and excess weight. There was a significant increase in both interlabial distance and height of the right nostril between the 2 evaluations (T1 and T2). There were no differences in the mean measurements of open bite or
Discussion
It is well known that obesity and various morphological facial characteristics influence respiratory quality and contribute toward both the emergence and aggravation of respiratory diseases, such as OSAHS.5, 6 Little is known regarding morphological craniofacial alterations caused by rapid, substantial weight loss after bariatric surgery. To establish a parameter of significant weight loss for the purpose of studying such outcomes, a single standard of percentage of excess weight loss (EWL%)

2023, Brazilian Journal of OtorhinolaryngologyCitation Excerpt :An increase in upper airway volume was observed, from 17,032 to 17,748.6 mm3 (6 months) and 18,262.3 mm3 (12 months; p < 0.05). Santos23 used lateral cephalometry to assess craniofacial changes after bariatric surgery (Roux-en-Y), without assessing OSA. On average, the participants lost 31.5 kg, equivalent to a 25% reduction in baseline weight, but the study did not assess the presence or severity of obstructive sleep apnea.
