EFFECTS OF ULTRASOUND-ASSISTED PRECONDITIONING ON CRITICALLY ISCHEMIC SKIN FLAPS: AN EXPERIMENTAL STUDY
(Elsevier Science inc, 2020) Yucel, Sercan; Gunay, Galip Kemali; Unverdi, Omer Faruk
This study evaluates the effect of ultrasound-assisted preconditioning on critically ischemic flaps. Ninety-eight Sprague Dawley rats were randomly divided into eight groups. Control, surgical delay, ultrasound and sham groups were designed. Modified McFarlane flaps were raised on the back of rats, and flap survival rate was assessed on post-operative day 14 in control, ultrasound and sham groups. Bipedicled flaps were created in the surgical delay group, and 14 d after delaying, all skin flaps were elevated. Statistically, flap survival rates of all ultrasound groups were significantly higher than the control group. Plasma vascular endothelial growth factor levels were increased in all ultrasound groups. Vessel counts did not show any difference between the groups. This study shows that the preconditioning by ultrasound can be used to improve the viability of ischemic skin flaps almost at a level close to the surgical delay.

Modified Cartilage Sparing Tip Plasty Technique for Extra Projection: Hemitransdomal Suture With Submucosal Dissection: A New Approach to Nasal Tip Dynamics
(Lippincott Williams & Wilkins, 2020) Yucel, Sercan; Unverdi, Omer Faruk
The nasal tip projection and rotation to be obtained with tip plasty play a key role in achieving successful results. Cartilage sparing techniques provide extra ease to reshape the cartilage in revision rhinoplasty. Freed dome cartilage eliminates the restricting forces of mucosa. The authors recommend to free the dome cartilage from mucosa during the tip plasty which ensures the desired dome shape and extra projection. A total of 218 patients who were operated between the dates of January 2017 and August 2018 were included in this study. About 3mm parts of the marked domes toward medial and lateral crurae were dissected from the mucosa. New domes were created with bilateral hemitransdomal sutures. The outcome of the operation was asked to the patients verbally and answers were recorded. Of 218 patients who were included in the study, 182 were females and 36 were males. Patients had a mean age of 26.5 years. The length of follow-up was 11.8 months. About 205 patients had primary rhinoplasty while 12 patients had secondary rhinoplasty and 1 patient had revision rhinoplasty. Of the patients, 89.9% (196/218) were very satisfied with the result and 7.4% (16/218) were satisfied, whereas 2.7% (6/218) were dissatisfied. Only 5 patients who were dissatisfied with the result underwent revision rhinoplasty operation. The combination of the modified free dome suture with the mucosal dissection in dome area provides achieving the desired tip projection and symmetry.

Recommended Surgical Margins for Basal Cell Carcinoma: Is 3 mm Safe Enough?
(Lippincott Williams & Wilkins, 2020) Unverdi, Omer Faruk; Yucel, Sercan; Berk, Osman Serdar
OBJECTIVE The primary aim of treatment of basal cell carcinoma (BCC) is the complete excision of the tumor. Reconstruction of the defect after surgical excision varies, depending on the location and size of the defect and the skin to be used in the reconstruction. In this study, investigators compared the rates of tumor positivity at the edges of BCC specimens excised with 3- or 5-mm surgical margins. METHODS Researchers analyzed data related to 113 patients with a preliminary diagnosis of BCC between August 2016 and June 2018. In total, 99 lesions from 91 patients not exceeding 2 cm in size excised with 3-mm (n = 53) or 5-mm (n = 46) surgical margins were included. Statistical analysis was performed using the chi(2) test. RESULTS After histopathologic assessment, 3 of 53 lesions that were excised with 3-mm surgical margins had a positive surgical margin, whereas none of the 46 lesions excised with 5-mm margins indicated a positive tumor presence. However, there was no statistical difference between the groups. CONCLUSIONS A 3-mm surgical margin may be sufficient and safe for BCC excision.
