Clinical effect of continuous pair triangular flap plasty on webbed penis / 中华泌尿外科杂志

Objective:To explore the safety and efficacy of continuous pair triangular flap plasty in the treatment of webbed penis.Methods:The clinical data of 5 patients with webbed penis treated by continuous pair triangular flap plasty in Tianjin Baodi Hospital from November 2020 to January 2021 were retrospectively analyzed. The average age was 18.2 (15-24) years old. Physical examination showed a webbed fusion between the ventral skin of the penis and the scrotal skin, the penoscrotal angle disappeared and penile erection was limited. The web extended to or exceeded the middle of the penis in the 5 cases. None of the 5 patients had other penile malformations. Taking the ventral midline of the penis and the junction of the penis and scrotum as the origin, a " Z-shaped" incision was made above and below it respectively, and two triangular flaps with the same size and shape but opposite direction were formed respectively. Then the triangular flaps were switched and sutured.Results:The average operation time of five patients was 13(10-20) minutes. The operative average blood loss was 1.6(1-3)ml. All patients had good wound healing and no surgical complications. Three months after operation, the appearance of the penis was satisfactory and erection was unrestricted.Conclusions:Continuous pair triangular flap plasty overcomes the disadvantages of traditional operation, and has the advantages of simple operation, good operation results and few complications. It is a good choice for the treatment of webbed penis.

Distal-triangular flap design for impacted mandibular third molars: a randomized controlled trial / 华西口腔医学杂志

OBJECTIVES@#This prospective study was performed to evaluate whether the distal-triangular flap was a practical alternative surgical approach for extracting mandibular third molars.@*METHODS@#Sixty participants with impacted mandibular third molars were randomly divided into three groups: group A, distal-triangular flap; group B, Szmyd flap; and group C, envelope flap. The impacted third molars were extracted by the corresponding flapping method. During a three-month follow-up observation after the extraction, the postoperative pain, swelling, mouth opening, and periodontal status were recorded and analyzed by ANOVA and chi-square tests.@*RESULTS@#The 60 participants had successful extraction and 3-month follow-up observation. No participant suffered from postoperative infections, lower lip disorder, or tongue sensory disorders. No statistical differences were found in the postoperative symptoms and signs of the three flap designs, such as postoperative pain, swelling, mouth opening, and periodontal status (@*CONCLUSIONS@#The distal-triangular flap was as safe and reliable as the Szmyd and envelope flaps but more advantageous because of its convenient operative field exposure and low requirement for the patient's mouth opening. Thus, the distal-triangular flap is one of the alternative flap options for extracting impacted mandibular third molars.

The influence of the envelope flap and triangular flap designs on postoperative complications after mandibular third molar removal / 天津医药

Objective To evaluate effects of two different flap designs (envelope flap and triangular flap) on complica?tions after the mandibular third molar surgery. Methods A randomized, self controlled clinical trial design was selected for 52 patients treated in the outpatient surgery of Stomatological Hospital Affiliated to Tianjin Medical University. Patients were treated with envelope flap design for lower third molar removal in one side and triangular flap on the other side. VAS scores were used to evaluate postoperative pain. The postoperative swelling was evaluated by patient`subjective index. The degree of the upper and lower incisor distance was used to evaluate trismus. Data of postoperative swelling, pain and trismus were re?corded 1, 2 and 7 days after surgery. Data of postoperative wound dehiscence, bleeding situation and alveolitis were also re?corded and compared between two groups. Results There were no significant differences in postoperative pain after 1, 2 and 7 days between two flap designs (P>0.05). After 1 and 2 days there was more severe facial swelling in triangular flap group than that of envelope flap group (Z=2.005, Z=2.017, P0.05). There were no signifi?cant differences in postoperative pain, alveolitis, bleeding and wound dehiscence between two groups (P > 0.05). Conclu?sion The envelope flap is more conductive to the early recovery in patients after surgery, but in the long term there is no ob?vious difference between the two flap designs.

Primary Correction of Unilateral Cleft Lip by the Tennison-Randall Method: Cases Report and Literatures Review

An experience of unilateral incomplete cleft lip repair by using bardach's triangular flap

Surgical Correction of Microform Cleft Lip by Small Triangular Flap

Cleft lip is one of the most common major facial malformation. The defect of the midline tissue on the upper lip is due to failure of the contact and fusion between mesenchymal tissues of the lip. Microform cleft lip is defined as the cleft of the lip with the minor degree of the deformity on the lip and the nose. The hallmarks of the microform cleft lip are a small notching of the vermilion, a vertical congenital fibrous band extending from the vermilion to the nostril floor, and a displaced alar cartilage on the cleft side. The surgical methods of microform cleft lip include Rose-Thomson straight line closure and Millard Rotation- advancement repair. Although those methods repaired the functional impairment effectively, they failed to achieve the cosmetic improvement because of the long incision scar on the upper lip. The authors applied Tennison's small triangular flap to the microform cleft lips of the 10 patients from July 1998 to January 2001. We excised the scar on the notch of the vermilion with minimal incision using Tennison's small triangular flap and repaired the discontinuity of orbicularis oris musculture. The asymmetric nostrils were also corrected appropriately. We followed up each case with constant intervals and could get good results esthetically without shortening of the upper lip and the contracture of the scar band.
