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.

OBJECTIVE: To compare the surgical outcomes of simple frenotomy and the 4-flap Z-frenuloplasty according to the articulation test values and tongue-tie classification in patients with ankyloglossia with articulation difficulty.
METHODS: prospective randomized study.
METHODS: Tertiary academic center.
METHODS: and methods: Children with ankyloglossia with articulation difficulty were randomly divided into 2 groups for surgical treatment. Patients were evaluated for the tongue-tie classification and articulation test before surgery. Three months after the operation, the frenulum classification and articulation test were re-evaluated to compare the differences in surgical outcome between the two surgical methods.
RESULTS: Out of 37 patients, 19 underwent the 4-flap Z-frenuloplasty and 18, the simple frenotomy. No differences were observed in the baseline characteristics of the patients assigned to both groups. Changes in the tongue-tie classification and improvement in the articulation test results were observed with both the surgical methods. Both surgical groups had significant improvement in the speech articulation test (consonants) but there was no difference in the speech outcomes between the surgical groups.
CONCLUSIONS: Although there was no significant difference in the surgical outcome between the two surgical methods, ankyloglossia patients showed improvement in a Korean speech articulation test 3 months after undergoing surgery to release the lingual frenulum.

Sacrococcygeal pilonidal sinus is one of common diseases in general department. However, it is characterised, for surgeons, by high post-surgical recurrence and high incidence of post-surgical wound complications. Due to that fact, this retrospective randomised clinical study was designed to evaluate the surgical procedure effect of Z-plasty (ZP), compared with convention simple excision (SE). A total of 67 patients from May 2015 to May 2019 in our department were studied into two groups randomly, the group of ZP and the group of SE. The patients\' characteristics, surgical data, hospital length of stay (LOS), and post-surgery complications were recorded. Statistical approaches were proceed with P-value analysis. The results are as follows. No significant differences were found between these two groups of the ages, gender distribution, Body Mass Index (BMI), smoking history, diabetes mellitus, and blood hypertension. The estimated blood loss, specimen volume, distance to anus, and drain output on the first day of post-surgery between the two groups were not statistically significant, either. However, surgical time in the ZP group was longer than that in the SE group (P < .0001). LOS in the ZP group was obviously shorter than that in the SE group (P = .0051). Furthermore, the patients of the ZP group were tending to suffer from fewer post-surgical complications than the ones of the SE group. In a conclusion, we hold the point view that the surgical procedure of ZP can lead a better outcome than SE because it demonstrated shortened LOS and fewer post-surgical complications.

Aponeurectomy remains the reference standard treatment for digit tethering by palmar fascial cords in Dupuytren\'s disease but is associated with a substantial complication rate. An alternative technique decreases metacarpophalangeal joint (MCPJ) flexion contracture by combining palmar segmental aponeurectomy with Z-plasty skin closure. The primary objective of this study was to assess range of motion of the operated ray after the procedure. The secondary objectives were to assess the complication rate and to determine the recurrence rate after at least 1 year.
Palmar segmental aponeurectomy with Z-plasty closure may provide the advantages of aponeurectomy while decreasing the surgical risk and recurrence rate.
A retrospective study was conducted in 16 patients with predominant MCPJ flexion contracture due to a well-defined palmar fascial cord. Anaesthesia was loco-regional. The Z-plasty design involved a longitudinal incision along the palmar cord with an oblique incision at each end at a 60° angle to the longitudinal incision. The length of the aponeurectomy was about 1.5cm, to allow full MCPJ extension.
In all, the 16 patients-13 males and 3 females-had 17 segmental palmar aponeurectomy procedures with Z-plasty closure. Mean operative time was 18minutes. Before surgery, mean loss of extension was 47° at the MCP joint and 15° at the corresponding proximal interphalangeal joint (PIPJ). Immediately after surgery, a 97% improvement in MCPJ extension was noted, leaving a mean extension deficit of 1.25°. Mean follow-up was 18.9 months. No complications occurred. Two patients experienced a recurrence.
Segmental palmar aponeurectomy as described by Moermans in 1991 improves extension similarly to extensive aponeurectomy but has a lower complication rate. Z-plasty provides good exposure of the pedicles and takes advantage of the greater pliability of the skin on either side of the cord to lengthen the skin by 75%, thereby limiting the risk of the complications seen with needle aponeurotomy. Segmental palmar aponeurectomy with Z-plasty has a role in the management of Dupuytren\'s disease with flexion contracture predominantly involving the MCPJ.

We compared two surgical procedures for de Quervain\'s disease that was not responsive to conservative treatment. Group A (simple release) consisted of 38 patients and group B (Z-plasty of the retinaculum) included 36 patients. The visual analogue scale score and the Disabilities of the Arm, Shoulder and Hand Score improved significantly after surgery; there were no statistical differences in outcome between the two groups. In group A, one patient required reoperation, two had subluxations of extensor tendons and two had temporary loss of sensation in the area of the radial nerve. In group B, two patients had temporary loss of sensation. The mean time to resolution of pain at the operative site was significantly shorter in group B. Both simple release and Z-plasty were effective surgical methods. Z-plasty allowed earlier return to activities of daily living but there was no statistical difference between the two groups in incidence of complication. Level of evidence: IV.

Pilonidal sinus is a common chronic disease of the sacrococcygeal region. The treatment varies according to the clinical presentation of the disease. Although many surgical methods have been suggested, an ideal method is still lacking because of high recurrence rates. The aim of this work is to assess the role of Z-plasty in promoting primary healing in pilonidal disease and to evaluate morbidity and recurrence. This study included 40 patients (36 males and 4 females) who underwent excision of sinus and Z-plasty closure for sacrococcygeal pilonidal sinus. The follow-up period ranged from 6 to 12 months. There were 36 males and 4 females with a median age of 25 years. The mean hospital stay was 2 days. The mean time to return to work after discharge from the hospital was 14 days. There were no recurrences, and all patients were satisfied with the cosmesis. Two patients (5 %) had numbness over the flap. Necrosis of flaps did not occur in any patient. Only three patients were noticed to have wound infection (7.5 %). Five patients (12.5 %) developed wound seroma. Although requiring some technical expertise, excision of sinus and Z-plasty offer superior results with respect to recurrence in the hospital stay and cosmesis of patients with pilonidal sinus.
