Hypertrophic scars arise from burn injuries because of persistent inflammation in the reticular dermis. Several risk factors promote this chronic inflammation. One is tension on the burn wound/scar due to surrounding skin tightness and bodily movements. High estrogen levels and hypertension are also important systemic risk factors. Thus, to prevent burn wounds from developing into hypertrophic scars, it is important to focus on quickly resolving the reticular dermal inflammation. If conservative treatments are not effective and the hypertrophic scar transitions to scar contracture, surgical methods such as Z-plasty, full-thickness skin grafting, and local flaps are often used.

In recent decades, advances in surgical anatomy, burn pathophysiology, surgical techniques, and laser therapy have led to a paradigm shift in how we approach burn scars and contractures. Scar excision and replacement with uninjured tissue, which predominated burn scar treatment for much of the 20th century, is no longer appropriate in many patients. A scar\'s intrinsic ability to remodel can be induced by reducing tension on the scar using various techniques for local tissue rearrangement. Often in combination with laser therapy, local flaps can optimally camouflage a burn scar with adjacent normal tissue and restore a patient more closely to their preinjury condition.

UNASSIGNED: The most important step in treating a pilonidal sinus is eradication by surgical excision. Over the years, various surgical techniques have been reported for wound closure, yet their management still poses a challenge. The current study compares the results of two different methods of wound management: secondary wound healing versus the Z-plasty surgical technique.
UNASSIGNED: The current clinical trial recruited 84 uncomplicated pilonidal sinus patients who were to undergo complete surgical excision of the pilonidal sinus. For wound healing, the 84 subjects were equally divided into two groups of 42 patients each. One group was selected for Z-plasty surgical wound closure and the other for the secondary healing mechanism. Outcomes measured consisted of demographic data, length of operation, complications, severity of pain, number of dressings, recurrence, and complete healing time.
UNASSIGNED: Age or sex distribution and the median BMI (kg/m²) did not significantly differ between the two groups. The length of the operation for Z-plasty subjects was significantly longer (P <0.0001). The median number of dressing changes for secondary wound healing patients was 38.69, which was significantly higher than the 4.95 dressing changes for the Z-plasty group. The total time recorded for complete wound healing was 21.61±4.27 days in the Z-plasty group and 41.23±24.28 days for secondary wound healing subjects, which was statistically significant. Twenty-four hours postoperation, patients in the secondary wound healing group had significantly more pain, and the Visual Analogue Scale scores of the Z-plasty and secondary wound healing groups were 3.42±0.76 and 6.09±1.2, respectively. Concerning the recurrence rate, there were no significant differences between the two groups. SPSS version 22 performed the analyses, and the independent t-test compared the continuous variables. A P value less than 0.05 was considered statistically significant.
UNASSIGNED: Z-plasty is a safe and effective procedure in terms of wound complications and recurrence rate. This method is also cost-effective and better received by patients.

BACKGROUND: A congenital constriction band (CCB) is a relatively common anomaly among limb malformations. However, the number of cases treated at a given center is limited and differences in techniques used by surgeons at each facility have a significant impact on the treatment outcomes. Several surgical methods have been reported, but a standard technique that yields consistent satisfactory results is still needed. Here, we introduce a novel technique for the treatment of CCB syndrome that uses a combination of wave-like skin incision and Z-axis Z-plasty.
METHODS: A wave-like incision was used for skin incision with the goals of achieving an accordion effect and a less noticeable post-operative scar. After the fibrous constriction band was completely excised, a Z-plasty of sufficient size in the Z-axis direction was performed on the dermis-inclusive adipose tissue. For over 10 years, this technique was applied to 11 sites in 6 patients. A retrospective study of the characteristics of these cases was performed, including age at surgery, gender, type of deformity, degree of constriction, types of examination, number of surgeries, and post-operative outcomes.
RESULTS: In all patients, a normal contour of the limbs was achieved and the hourglass-like deformity caused by the constriction band was satisfactorily improved. No additional corrective surgeries were needed, there was no abnormal growth of the treated limbs, and scarring was aesthetically acceptable in all cases.
CONCLUSIONS: The novel technique described here uses deep subcutaneous fat to correct the hourglass-like deformity and restores a normal limb contour, while the wave-like skin incision minimizes post-operative scarring.

The square flap method has been successful in releasing contracture bands at various body regions. However, the original square flap method alone may not be efficient in releasing long contracture bands. We, therefore, proposed an extended design to the traditional design, which is called the \"square-plus flap.\" A 4-year-old girl presented with a postburn web-like contracture band over the right axilla. We marked a square flap technique at the center of the contracture band and then two additional Z-plasties were placed on both edges of the flap. After the release and securing of the square flap, the adjacent distal Z-plasty was then transposed and sutured in their new locations. We do not need to incise the proximal Z-plasty as we could achieve complete relaxation of the contracture band. This novel modification can be added to the plastic surgeon\'s armamentarium for releasing long postburn contracture bands involving distinct body regions.

We report the case of a 35-year-old male patient who presented with a right zygomaticomaxillary complex fracture, which was five months old. It was associated with ectropion over the right eye. Diagnosis was made by clinical examination and confirmed by computed tomography, which included a three-dimensional reconstruction view. The patient was concerned about a projecting deformity over the right side of his face and blurring of vision. Surgical rationale of treatment was to easily access the surgical site for the correction of deformity and to achieve the desired facial contour and ectropion correction with uneventful postoperative healing. Deformity at the right zygomatic arch was exposed by a hemicoronal incision. Ectropion over the lower eyelid was addressed by performing Z-plasty. Outcomes were esthetically pleasing with no loss of motor and sensory functions loss. The patient was followed up for six months.

During or after the orthodontic closure, persistent diastemas are frequently the result of a high frenum attachment. A labial frenectomy is a complete removal of the frenum attachment, which typically attaches to the space between the upper two anterior teeth and the centre of the upper lip. It might be required if there is space between the teeth due to a frenulum positioned too high on the gums. Many surgical technique modifications, including Miller\'s technique, Z-plasty, and V-Y-plasty, have been established since the conventional classical frenectomy procedure was initially presented to cope with the difficulties associated with an aberrant labial frenum. This case report demonstrates that a Z-plasty approach was used to remove the 21-year-old female patient\'s high papillary-type labial frenum attachment and how orthodontic treatment led to the closure of the midline diastema. For several reasons, the frenectomy procedure with Z-plasty proved to be reliable and yielded outstanding aesthetic outcomes for the removal of the aberrant labial frenum connection. Understanding Z-plasty will enable primary intention-based tissue healing, reduce the risk of tissue contractures, shorten the patient\'s recovery, and enhance the patient\'s aesthetic outcomes.

BACKGROUND: Amniotic band syndrome is a fetal entrapment in strands of amniotic tissue. This condition causes multiple deformities ranging from simple constricting bands to lymphedema, autoamputation, syndactyly and other congenital anomalies. Reconstructive surgery is the main treatment for ABS.
METHODS: A 4-year-old male presented with multiple constricting bands affecting both hands in addition to an incomplete syndactyly between the third and fourth left digits. A two-staged operation was performed to repair the deformities with 6 months interval. Series of Z-plasties were used to release the constricting bands and the syndactyly was separated by a web zigzag incision approach and full-thickness skin grafting.
CONCLUSIONS: Management of ABS must be individualized. The urgency of the surgical release depends on the depth of the constricting bands and their influence on circulation and lymphatic drainage. Superficial bands can be released electively for cosmetic appearance while deep bands should be released as soon as possible. The separation of syndactyly should be done at the first year of life to maintain the digits functionality and parallel growth.
CONCLUSIONS: This paper emphasizes the importance of early repair of constricting bands associated with syndactyly to avoid the consequences of the delay on digital growth.

UNASSIGNED: Treating burn scar contractures remains challenging for reconstructive surgeons; no clear guidelines declare the optimal and most effective technique. We evaluated the efficacy of local flaps in treating patients with post-burn contractures.
UNASSIGNED: This retrospective study included 243 patients with post-burn contractures referred to Taleghani Hospital (Khuzestan, southwest Iran) for local flap reconstruction from 2011 to 2020. Patients\' demographic data, detailed descriptions of scars, surgical procedures, and flap outcomes were assessed. A plastic surgeon conducted all surgical procedures, the goals of which were to release the scar and cover the defect. Joint range of motion (ROM) (according to goniometric measurements), complications, need for second-stage surgery, and patient satisfaction were assessed.
UNASSIGNED: After scar release, 70.4% of joints were covered with a Z-plasty and similar local flaps, 26.1% with a Z-plasty plus skin grafts, and 3.5% with only skin grafts. The outcome after one year revealed a significant improvement in mean ROM (by 45.80% of the normal ROM; P< 0.001). The mean functional and aesthetic satisfaction scores were 9.45 and 7.61 out of 10, respectively. The complication rate was 10.82%: re-contracture occurred in 3.82%, flap tip necrosis in 1.27%, and partial flap necrosis in 0.31%.
UNASSIGNED: Simple local flaps such as the Z-plasty are safe and effective in covering the joint following post-burn contracture release. Due to the feasibility, minimal need for facilities, steep learning curve, acceptable functional and aesthetic outcomes, and low complication rate, we strongly recommend the Z-plasty for reconstructing burn contractures, particularly in LMICs.

UNASSIGNED: Macrostomia is a congenital deformity found in Tessier no. 7 facial clefts defined as an enlargement of the mouth at the oral commissure. Several techniques are described in literature to achieve optimal functional and aesthetic results, with varying results and surgeon preferences. In this case series we report surgical repair of macrostomia with a vermillion square flap method for the oral commissure combined with either Z-plasty or W-plasty closure for the skin.
METHODS: A retrospective case analysis of 12 patients with macrostomia operated over the past 7 years at our plastic surgery division was performed (by two different operators; 11 cases by A.S. and 1 case by R.S.). Clinical features of the patients were analyzed through photography documentation, and patient description such as age of operation, operation technique, and complications were obtained through patient records. Macrostomia was corrected with a vermillion square flap method for commissure, overlapping muscle closure, along with either Z-plasty or W-plasty closure for the skin. Quality of lip commissure position, symmetry, thickness of vermillion, and scar result were recorded.
UNASSIGNED: In all twelve patients repaired with the overlapping muscle closure and square flap, the lip commissures were formed with satisfactory shape, position, and thickness with no commissure contracture during the follow up period. The Z-plasty was a simpler method compared to the W-plasty, and resulted in comparable scars. One patient (adult with hemifacial macrostomia and W-plasty skin closure) underwent revision surgery for more accurate symmetry and position of the oral commissure.
CONCLUSIONS: There are many varieties of surgical repair for macrostomia, and each method should be adjusted and combined according to each patient. Overall, macrostomia repair with this technique combination produced satisfactory aesthetic and functional results in all twelve patients. Z-plasty for skin closure after muscle and vermillion closure was a simpler technique and resulted in comparable scars than W-pasty closure in this case series.
