Title: Deep Temporalis Fascia Blanketing Supra- SMAS (superficial musculoaponeurotic) layer Versus Sub-SMAS layer dissection and preservation in preventing nasal dorsal irregularities in Arabic Thick Skin Patients
Biography:
Dr. Mohammed Saad Aldin Aly Elsayed, MD Honorary Assistant professor at the faculty of medicine, the department otorhinolaryngology, head and neck surgery and member of the rhinoplasty society of Europe and pan Arabic society.
Abstract:
Background:
Rhinoplasty is a complex surgical procedure used to correct nasal deformities. The main aim of this procedure is to improve the function and aesthetic aspect of the nose, enhancing facial harmony and the symmetry of the nose. It is considered as one of the most challenging operations in the field of Otolaryngology practice. In primary rhinoplasty, the two common techniques used are sub superficial musculoaponeurotic system (Sub-SMAS) layer dissection and Supra SMAS deep Temporalis Fascia (DTF)blanketing for prevention of dorsal nasal irregularities in thick skin Arabic patient . The aim of this study is to compare the irregularity of the nasal dorsum after rhinoplasty between (DTF)blanketing supra SMAS layer and(Sub-SMAS) layer dissection and preservation in primary thick skin Arabic rhinoplasty surgery .
Methods:
The study was approved by institutional review board (IRB). A retrospective chart study was conducted on (64) patients who presented to (ENT Out Patient Department) and underwent primary rhinoplasty at tertiary care, Saudi Arabia. Patients were divided equally into2 groups,50%(32) Patients underwent (DTF)blanketing .and 50%(32) patients underwent(Sub-SMAS) layer dissection. Data was collected by observing the preoperative and postoperative dorsal aesthetic lines symmetry outcomes .Data were tabulated using Microsoft excel sheet,SPSS used for Statistical analysis .Comparison between groups made by Student’s, t-test and Chisquare test for categorical Values
Result:
Postoperative nasal dorsal aesthetic line symmetry observation in thick skin Arabic patient score was given for both the groups raging from (1,2,3,4,5), 1 means-0% marked dorsal aesthetic line symmetry,2- 25% symmetry, 3- 50% symmetry four 75% symmetry and 5-100% symmetry. It was seen that25.8% of patient with temporalis fascia blanketing supra SMAS layer had a score (5), 12.9% had score International Journal of Scientific & Engineering Research Volume 8, Issue 9, September-2017 185 (4), 38.7% score (3), 12.9% score (2) and 9.7% had score (1), while 36.4% of patient with(Sub-SMAS) layer dissection had score (5), 33.3% score (4) , 24.2% score (3) and 6.1 % score (2). The mean score in patients before (DTF) blanketing supra SMAS. was 2.25 and 3.32 after the surgery, while the mean score in patients (Sub-SMAS) layer dissection group was 1.97 and 4 after the surgery. The postoperative dorsal nasal irregularity observation showed that 87.1% of patients with (DTF)blanketing supra SMA Slayer,have a regular nose while 12.9% of patients have irregular nasal dorsal.87.9 % of patient with (Sub-SMAS) layer dissection have a regular nasal dorsum. while 12.1 % of them have irregular nose as the t test was significant.

Abstract:
According to Jones, oxidative stress (OS) has been defined as an imbalance between reactive oxygen species or ROS (including free radical and non-free radical species) and antioxidants in favor of the formers, leading to a disruption of the redox signaling and/or molecular damage to lipids, proteins and DNA. A promising but always under explored way to evidence OS is to use skin as a matrix. Having the largest surface area in the body, skin is a major target for oxidative stress, as it is continually exposed to external aggressions. The present talk is devoted to the potential use of the PAOT-Skin® technology based on electrochemical application for evidencing OS in a non-invasive way in the skin matrix. Data related to robustness and validation of the method will be examined.
In a study performed on 30 healthily subjects, we were able to evidence a negative and significant correlation between the PAOT-skin score ® and blood lipid peroxides (r = -0.43, p = 0.020), copper (r = -0.42, p = 0.022) and the Cu / Zn ratio (r = -0.49, p = 0.006). Statistical analysis revealed that the PAOT-skin score ®was positively correlated with the gamma-tocopherol/alpha-tocopherol ratio (r = 0.43; p = 0.020).
Other data on urine samples also indicate a positive correlation between PAOT-skin score® and the polyphenols/creatinine ratio (r = 0.41; p = 0.017) and a negative correlation with the oxidized DNA/creatinine ratio (r = -0.48; p = 0.0092).
