Abstract
BACKGROUND
Nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. This study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry.
METHODS
Fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. Objective assessment was performed by clinical examination and rhinomanometry before and after rhinoplasty.
RESULTS
Nasal obstruction had no significant difference before and after rhinoplasty and no significant difference was observed between surgical techniques. Right, left and total nasal flow and resistance were different before and after surgery but were not significant. Base of the nose was not significantly different between two groups, but nasal projection was 2 mm in the the group who underwent overlapping lateral crura technique and the difference was statistically significant. Our study showed that both overlapping lateral crura and spreader graft technique were beneficial in rhinoplasty and they could provide enough internal nasal valve support. The overlapping lateral crura was an appropriate surgical technique for tip projection in comparison to spreader graft.
CONCLUSION
The overlapping lateral crura technique was shown to be a better surgical way for tip projection in comparison to spreader graft.

Abstract
BACKGROUND
It has been reported that systemic administration of allopurinol improves cell survival. This study was aimed to evaluate effects of allopurinol on skin flaps in dogs.
METHODS
Twenty dogs underwent one skin flap surgery with a 2-week interval. The first procedure was performed according to the standard protocols. The second phase was started by a 1-week pretreatment with allopurinol. Length of the necrotic zone was measured and recorded daily. At each phase, flaps were removed and sent for histopathological study after 1 week observation.
RESULTS
Mean length of the necrotic zone in allopurinol treated skin flaps has been significantly less than normal flaps over all 7 days of observation (p<0.0001). Histopathology study showed less inflammation and more normal tissue structure in the allopurinol treated skin flaps.
CONCLUSION
It was demonstrated that systemic administration of allopurinol significantly improved skin flap survival.

Abstract
BACKGROUND
Dorsal augmentation of the nose for aesthetic and reconstructive purposes is an important issue in rhinoplasty surgery. This study aimed to compare the two methods of dice cartilage wrapping for dorsal augmentation of the nose including temporalis fascia and alloderm.
METHODS
In a clinical trial study, 50 patients who needed to augment the nasal dorsum, were enrolled and randomly allocated to two equal groups. In the first group, diced cartilage graft of the patient was wrapped in temporalis fascia and in the second group, a thin sheet of alloderm was used for this purpose. After one year follow up, satisfaction of patients and the expert panel were compared in two groups. Also mean increase in dorsal height was measured and compared in two groups.
RESULTS
The mean increase of dorsal nasal height one year after surgery in the alloderm and temporalis fascia was 3.13±0.49 and 3.42±0.33, respectively and in the fascia group was significantly higher (p=0.02). The mean of patients’ satisfaction in the two groups of alloderm and temporal fascia groups was 7.48±0.92 and 8.04±0.89, respectively (p=0.03). The mean satisfaction of expert panel in the two methods was 7.56±0.81 and 7.7±0.63, respectively (p=0.5).
CONCLUSION
The use of temporal fascia for covering the diced cartilage in augmentation of nasal dorsum had better results than the alloderm. Patients satisfaction and mean dorsal height was higher in temporal fascia group.

Abstract
BACKGROUND
Given the potential usefulness of Acellular Dermal Matrices (ADM) for wound healing, we aimed to evaluate the stability, histological characteristics, and effectiveness of ADM compared with cryopreserved dermis (CPD) in rat models.
METHODS
This experimental study was conducted in the Department of Surgery, Isfahan University of Medical Sciences, Isfahan, Iran, from January to March 2015. The prepared ADM and CPD were transplanted to the full-thickness skin defects on the back of Sprague-Dawley rats. Forty-five days after grafting, the tissues were harvested for histological examination. These two types of the dermis' quality and stability were compared with consideration of the following factors; inflammation, fibroblasts migration, vascularization, collagen formation, capsule formation, and microabscess formation.
RESULTS
From 19 selected rates, nine received CPD, and ten were treated with ADM. After transplantation, the mean (SD) weight of ADM and CPD grafts were 1.74 (0.07) and 1.45 (0.77), respectively (P<0.001). The frequency of inflammation was significantly higher in CPD grafts (P<0.01). Higher grades of collagen organization, fibroblast spreading, and vascularization were more frequent in ADM grafts (P<0.01). The frequency of capsule and microabscesses formation was not significantly different between studied groups.
CONCLUSION
ADM have a superior effect than CPD in the wound healing process. Both samples had a similar effect in capsule and microabscesses formation and higher costs of ADM preparation. According to the physicians' decision and evaluation of the process's cost-effectiveness, CPD could be appropriately used as an alternative to ADM.

Abstract
Abstract
Background: Rhinoplasty is one of the most common plastic surgeries and a challenging procedure for people with thick nasal skin. There are several techniques to improve the outcome of the operation.
Methods: Our study is a double-blind randomized controlled trial conducted in Esfahan, Iran in 2020. Seventy participants were equally divided into two groups (35 people). In the control group, only rhinoplasty was performed without SMASectomy and in the intervention group, rhinoplasty was performed with SMASectomy. The results were obtained and the satisfaction of patients and physicians was collected through patient examination and a questionnaire. Statistical analysis of data was calculated by SPSS software version 23 at a significance level of less than 0.05.
Results: The mean total skin thickness before surgery in the two groups was equally, which showed a significant difference between the two groups at after 12 months (P <0.05). Comparison of 3, 6 and 12 months after rhinoplasty in the two groups showed that the percentage of patient, doctor, hairdresser and nurse satisfaction, in 12 months after rhinoplasty, in the intervention group compared to the control group had a significant increase (P <0.05). Furthermore, in the control group 2.85% and in the intervention group 5.71% bleeding was observed. No other complications were observed in any of the groups.
Conclusion: Overall, SMASectomy, which is performed simultaneously with rhinoplasty, is considered as an important technique in rhinoplasty. As we observed in our study, the complications of these surgeries in patients were very small.

Abstract
Background: Despite the increasing popularity of cosmetic surgeries, some patients still experience skin problems, particularly those with thick nasal skin. Isotretinoin is a commonly used drug for severe acne, and its effects on rhinoplasty aesthetic results have recently been studied. This placebo-controlled clinical trial aimed to investigate the effects of topical tretinoin gel on the cosmetic outcomes of rhinoplasty in patients with thick nasal skin.
Methods: Forty-nine individuals were randomly allocated to either the treatment group or the control group in Mashhad, Iran from 2019 to 2021. The treatment group received topical tretinoin gel (0.05%) beginning on the 31st postoperative day and continued for six months, while the control group received a usual dermatological recommendation as a placebo. Patients were assessed during the first, third, and sixth months after the intervention, and their cosmetic results were evaluated by an expert surgeon and dermatologist.
Results: There were no significant differences in baseline features between the two groups. The median score given by the surgeon was not significantly different between the groups. However, the median score given by the dermatologist was significantly higher in the treatment group during the first, third, and sixth months (P<0.001). Patient satisfaction scores were also significantly higher in the treatment group during the third and sixth months compared to the control group. (P=0.02 and 0.01, respectively).
Conclusion: Topical tretinoin gel could effectively reduce acne in patients with thick nasal skin after rhinoplasty and increase patient satisfaction in the early months following surgery. However, it did not significantly affect final cosmetic outcomes.
