Abstract: 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.
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 rhinoplasty.
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 Studentā??s, t-test and Chi square test for categorical
values.
Result: postoperative nasal dorsal aesthetic line symmetry observation 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.
Conclusion: (Sub-SMAS) layer dissection is superior to the (DTF) blanketing supra SMAS layer.in the nasal dorsal
aesthetic lines outcomes, while there is no significant difference in nasal dorsal regularity between the two groups.
SubSMAS layer dissection is superior to the supra SMAS(DTF) blanketing as observed in this study , and also offers
the advantage that it can be obtained from the same operative site rather than obtaining .TF from a different site
