the Z Plasty contributes to the coalescence of a chronic non healing wound
International Wound Journal, 2021Co-Authors: Xinling Zhang, Huier Wangguan, Yidan Sun, Pengbing Ding, Xin Yang, Zhenmin ZhaoAbstract:This study aimed to explore the treatment effect of Z-Plasty on a non-healing wound. A total of 72 patients diagnosed with a chronic non-healing wound in Peking University Third Hospital from November 2009 to August 2019 were retrospectively analysed. Among them, 27 patients were treated with Z-Plasty, and 45 patients were treated with the general method. Detailed patient information was retrieved from medical records, including age, gender, body mass index (BMI), alcohol, smoking, and comorbidities (diabetes mellitus, hypertension, heart disease). Surgical parameters included operation time and intraoperative blood loss. Wound swelling, epidermal blisters, wound edge colour, and skin temperature at 1 day after surgery were assessed to evaluate the blood supply of the wound. Surgical complications included infection, haematoma, dehiscence, and non-healing within 2 weeks postoperatively. Student t test (for continuous data) and Chi-square test (for categorical data) were conducted to determine the statistical difference. We found no significant differences in age, gender, BMI, alcohol, smoking, and comorbidities between the two groups. Z-Plasty did not show any advantages in the surgical time, invasive blood loss, hospital days, and hospitalisation expenses. The incidence of abnormal wound edge colour with Z-Plasty was significantly lower than that with the general treatment (P < .05), and the Z-Plasty enables better healing of the patient's wound (P < .05). Z-Plasty promoted better recovery of chronic non-healing wounds than direct suturing.

Z-Plasty of the alar subunit to correct nasal vestibular stenosis.
Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery, 2014Co-Authors: Natasha Choudhury, Ahmad Hariri, Hesham SalehAbstract:Nasal vestibular stenosis can result in a challenging cosmetic deformity, for which a variety of techniques have been described, including scar excision and replacement with local flaps, composite or cartilage grafts, with or without stents. We describe the Z-Plasty technique to widen the alar base and assess patient satisfaction from the surgery. A retrospective review of patients who underwent Z-Plasty to the alar subunit for nasal vestibular stenosis over a 4-year period was conducted. Demographic data and patient satisfaction were evaluated using pre- and postoperative visual analog scores and RhinoPlasty Outcome Evaluation questionnaires. Eight patients underwent the procedure, and all confirmed significant improvement in their esthetic outcome. We describe our Z-Plasty technique to the alar base and review patient satisfaction.

Modified Z-Plasty of the Ala to Relieve Nasal Vestibular Stenosis
Otolaryngology–Head and Neck Surgery, 2013Co-Authors: Ahmad Hariri, Natasha Choudhury, Hesham SalehAbstract:Objectives:Nasal vestibular stenosis results in significant functional impairment and cosmetic deformity. Various techniques can be used, including excision of the deformed segment and replacement with healthy tissue using local flaps, composite or cartilage grafts, with or without stents. W-Plasty, Z-Plasty, and double-cross Plasty techniques have also been described. We aimed to evaluate the following outcome measures: 1) Describe our modified Z-Plasty technique to widen the ala base. 2) Report patient satisfaction with respect to functional and cosmetic improvement.Methods:A retrospective study over a 4-year period was conducted on patients who underwent modified Z-Plasty of the ala. This is performed under general anaesthetic, with infiltration of 2% lignocaine, and 1:80,000 adrenaline to the lateral alar margin and adjacent soft tissue, overlying the piriform aperture margin. A Z-Plasty incision is made around the lateral ala and anterior nasal process of maxilla. The two triangular flaps are transpo...

Some thoughts on choosing a Z-Plasty: the Z made simple.
Plastic and reconstructive surgery, 2000Co-Authors: Donald A. HudsonAbstract:The Z-Plasty and its variations are techniques commonly performed in plastic surgery. However, there are few descriptions and comparisons of the various types of Z-Plasty. This article examines the mechanics of the Z-Plasty and its variations. Understanding the geometry of the different variations will allow selection of the most appropriate Z-Plasty for contracture release.

TREATMENT OF VELOPHARYNGEAL INCOMPETENCE BY THE FURLOW Z-Plasty
Annals of plastic surgery, 1995Co-Authors: Donald A. Hudson, D.b. Fernandes, Adriaan O. Grobbelaar, R. LentinAbstract:Velopharyngeal incompetence occurs in approximately 25% of cases after primary palatoPlasty. There is controversy regarding the best method of surgical management of velopharyngeal incompetence. Between 1986 and 1993, 13 children with velopharyngeal incompetence after primary palatoPlasty underwent Furlow Z-Plasty repair. All children were assessed by a speech therapist and with videofluoroscopy pre- and postoperatively. The Furlow Z-Plasty was performed at a mean age of 7.8 years (range, 4-12 years). Eleven children achieved normal resonance, and all 13 demonstrated improved velopharyngeal function on videofluoroscopy. The Furlow Z-Plasty is effective treatment for children with velopharyngeal incompetence.

Topology, Geometry, and Mechanics of Z-Plasty.
Physical review letters, 2018Co-Authors: Elisabetta A. Matsumoto, Haiyi Liang, Lakshminarayanan MahadevanAbstract:Reconstructive surgeries often use topological manipulation of tissue to minimiZe postoperative scarring. The most common version of this, $Z$-Plasty, involves modifying a straight line cut into a $Z$ shape, followed by a rotational transposition of the resulting triangular pedicle flaps, and a final restitching of the wound. This locally reorients the anisotropic stress field and reduces the potential for scarring. We analyZe the planar geometry and mechanics of the $Z$-Plasty to quantify the rotation of the overall stress field and the local forces on the restitched cut using theory, simulations, and simple physical $Z$-Plasty experiments with foam sheets that corroborate each other. Our study rationaliZes the most typical surgical choice of this angle, and opens the way for a range of surgical decisions by characteriZing the stresses along the cut.
