Single vs. Double-Opposing Z-Plasty: Evaluating Their Impact on Palatoplasty Postoperative Outcomes.

BACKGROUND: The double-opposing Z-plasty is a fundamental approach for cleft palate repair. Recently, some surgeons have begun implementing a single Z-Plasty, igniting discussions on the most effective technique for enhancing postoperative outcomes. Consequently, this study sought to evaluate the outcomes of employing single and double Z-plasties within the modified Sommerlad-Furlow technique. METHODS: 116 cleft palate patients undergoing primary surgical repair were divided into two groups: those treated with the Sommerlad-Furlow method using a double-opposing Z-plasty (S.F.2.Z.P. group, n = 58) and those receiving a single nasal Z-plasty (S.F.1.Z.P. group, n = 58). Data on cleft type and width, soft palate length, palatal fistula, and velopharyngeal function were collected. Mann-Whitney test compared the mean values between groups. RESULTS: The S.F.2ZP group demonstrated a statistically significant increase in soft palate length compared to those in the S.F.1ZP group (p = 0.008). However, the S.F.1ZP group demonstrated adequate soft palate length (7.9 ± 2.8 mm) compared to the S.F.2ZP group (9.3 ± 2.8 mm). The velopharyngeal function was good in both groups, with no significant differences (P = 0.52). While the proper velopharyngeal closure was 81% in the S.F.1ZP group and 87.9% in the S.F.2ZP group, velopharyngeal insufficiency was 10.3% and 5.2%, respectively. The rates of persistent palatal fistula were 5.2% in the S.F.1ZP group and 3.4% in the S.F.2ZP group, with no significant differences found between both groups (P = 0.64). CONCLUSIONS: There were no significant differences in crucial outcomes such as velopharyngeal function and the incidence of persistent palatal fistulas, indicating the effectiveness of both techniques. While the double-opposing Z-plasty demonstrated a statistically significant increase in soft palate length, the a nasal Z-plasty demonstrated adequate soft palate length which sufficiently enables effective velopharyngeal closure. These outcomes suggest that a single Z-plasty is both effective and easy to perform, making it a valuable surgical approach for achieving the desired outcomes.. CLINICAL RELEVANCE: The current study suggests that although the soft palate may not be as elongated with nasal Z-plasty alone compared to the double Z-plasty, it sufficiently enables effective velopharyngeal closure.

"Folding Fan Flap": A Novel and Dependable Surgical Technique for Crow's Feet Correction by Z-Plasty of Orbicularis Oculi Muscle.

OBJECTIVE: The challenge of crow's feet surgical correction is to minimize the complication caused by orbicularis oculi muscle (OOM) resection while ensuring the operative effect. This study aims to propose a novel technique to solve this problem and evaluate its efficacy. METHODS: From January 2022 to April 2024, all patients who received "Folding fan flap" in our institution were included. The outer third of the OOM below the lateral canthus was dissected and received Z-plasty to exchange width for length and reconstruct the muscle dynamics in a non-circular direction. Preoperative and postoperative smiling crow's feet were assessed by two independent physicians using the Lemperle wrinkle scale. At least six months after surgery, patient satisfaction with wrinkle correction, naturalness of facial expression, and local flattening was subjectively evaluated on a five-point scale. Complications including hematomas, incomplete eyelid closure, facial stiffness, and forehead numbness were recorded. RESULTS: A total of 32 patients (63 sides) were included with a mean follow-up of 13.9 ± 5.2 months. Postoperative assessments showed a significant reduction in Lemperle's score from 4.8 ± 0.4 to 1.5 ± 0.5 (P=0.000). Regarding the satisfaction of surgical outcomes and the naturalness of facial expressions, thirty patients (93.8%) were very satisfied. There were no severe complications such as hematomas and incomplete eyelid closure. CONCLUSION: Preliminary clinical studies demonstrated the efficacy of this technique in ensuring outcomes while preserving normal dynamic expressions. By Z-plasty of the outer circle of OOM, the muscle dynamic was successfully modified rather than eradicated.

Preoperative Velopharyngeal Closure Predicts Hypernasality Outcomes of Secondary Furlow Double-Opposing Z-Plasty.

OBJECTIVE: To determine if preoperative velopharyngeal closure percentage (VCP) is predictive of successful Furlow double opposing Z-plasty (DOZP) and subsequently determine the optimal velopharyngeal closure cutoff for successful DOZP. DESIGN: Retrospective study. SETTING: Tertiary academic center. PATIENTS: 110 patients with repaired cleft lip and palate having hypernasality treated with DOZP. INTERVENTIONS: Speech videofluoroscopy images were used to obtain the preoperative VCP and other measurements. MAIN OUTCOME MEASURES: Changes in hypernasality scores using the Cleft Audit Protocol for Speech-Augmented-Americleft Modification (CAPS-A-AM) rating system were used as the primary outcome measure. A successful DOZP was defined as a postoperative hypernasality score of ≤ 1 or an improvement of 2 or more scores from baseline. A receiver operating characteristic (ROC) curve was calculated to determine preoperative VCP cutoff. RESULTS: There were 110 patients who underwent DOZP for treatment of velopharyngeal insufficiency. Of these patients, 94 (85%) had successful surgery as determined by their postoperative CAPS-A-AM hypernasality score. Preoperative VCP was a statistically significant predictor of successful DOZP (P < .0001). The ROC curve with Youden index (J) determined a cutoff (c*) of 55% preoperative VCP or greater to optimize surgical success rate. Grouping by preoperative VCP showed that surgical success increases directly with preoperative VCP, and patients with low VCP had above a 50% success rate in reducing hypernasality scores. CONCLUSIONS: Preoperative VCP was significantly associated with improved hypernasality ratings postoperatively. A preoperative VCP of ≥55% may be used to help predict success of Furlow palatoplasty treatment. Patients with lower VCP can still benefit from secondary DOZP.

A Single Institution 19 Year Comparison of Furlow and Straight Line Palatoplasty Techniques in Bilateral Cleft Lip and Palate.

OBJECTIVE: This study aims to compare patients' speech correcting surgery and fistula rates between the Furlow and Straight Line (SLR) palatoplasty techniques when combined with greater palatine flaps for complete bilateral cleft lip and palate (BCLP) repair. DESIGN: This was a single-center IRB approved retrospective cohort study. SETTING: This study took place at an urban tertiary academic center. PATIENTS, PARTICIPANTS: All patients with BCLP anomalies that underwent repair between January 2003 and August 2022 were included. Patients with index operations at an outside institution or incomplete medical charting were excluded. INTERVENTIONS: A total of 1552 patients underwent palatoplasty during the study period. Of these, 192 (12.4%) met inclusion criteria with a diagnosis of BCLP. MAIN OUTCOME MEASURES: Primary outcomes of this study included rate of fistula and incidence of speech correcting surgery. Secondary outcomes included rate of surgical fistula repair. RESULTS: One hundred patients underwent SLR (52.1%) and 92 Furlow repair (47.9%). There was no significant difference in fistula rates between the SLR and Furlow repair cohorts (20.7% vs. 15.0%; p = 0.403). However, SLR was associated with lower rates of speech correcting surgery when compared to the Furlow repair (12.5% vs. 29.6%; p = 0.011). CONCLUSIONS: This study compares the effect of Furlow and SLR on speech outcomes and fistula rates in patients with BCLP. Our findings suggest that SLR resulted in an almost three times lower rate of velopharyngeal dysfunction requiring surgical intervention in patients with BCLP, while fistula rates remained similar.

Comparative analysis of length gain provided by five-flap f-flasty and fouble f-plasty fechniques for correction of digital flexion contractures.

INTRODUCTION: Persistent postburn flexion contractions of the digits present challenging deformities. The surgical goal is to lengthen the linear scar band on the flexion surface of a finger through local tissue rearrangement using different z-plasty techniques. This study aimed to analyse the length gain and compare outcomes between 5-flap z-plasty and double serial z-plasty techniques for correcting digital flexion contracture. PATIENTS & METHOD: This retrospective study was conducted from November 2022 to January 2024 on patients who presented with digital flexion contractures caused by volar linear scar contracture and who needed surgical intervention. All patients who underwent correction via the 5-flap z-plasty or double z-plasty technique were categorized into two groups. RESULTS: A total of 12 patients were included in this study. All patients successfully achieved complete release of their digital contracture in both groups. While there was a significant increase in the length of the contracture band and extensor lag angle postoperatively in both groups, the mean increase in band length for patients treated with five-flap Z-plasty was significantly greater than that for patients treated with double z-plasty (63.667±13.125% vs. 41.333±12.1764%, respectively). CONCLUSION: The 5-flap Z-plasty technique could be a more favourable alternative to the frequently used double z-plasty method due to its ability to achieve a superior rate of elongation in the contracture band and restore finger function when treating linear digital flexion contractures.

Comparison Study of 5-flap Z-Plasty and Double Z-Plasty for Interdigital Pocket Web Contractures.

PURPOSE: The aim of this study was to compare the improvement in abduction and change in web slope between 5-flap z-plasty and double z-plasty for post-burn or post-trauma interdigital pocket web contractures. METHODS: We retrospectively reviewed 16 webs in 11 patients with post-burn or post-trauma interdigital pocket web contractures. Seven patients underwent 5-flap z-plasty and 4 double z-plasty. The abduction and slope angles of the affected fingers were measured before surgery and every 3 months after surgery. RESULTS: The follow-up time ranged from 12 to 36 months. The postoperative abduction angle improved in both groups. There was an increase of 19° ± 4° in the mean abduction angle after surgery in the 5-flap z-plasty group compared with a mean of 12° ± 2° in the double z-plasty group; the postoperative decrease in the web slope angle was 30° ± 5° and 22° ± 2°, respectively. All patients were able to actively move the affected webs and fingers with no pain or other discomfort. CONCLUSIONS: Five-flap z-plasty can be considered a better alternative to double z-plasty for interdigital pocket web contractures based on the improvement in abduction angle and changes in the slope angle. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Simultaneous Furlow Palatoplasty and Tonsillectomy for the Treatment of Velopharyngeal Insufficiency and Tonsillar Hypertrophy.

OBJECTIVE: To determine whether performing tonsillectomy at the time of Furlow palatoplasty for the treatment of cleft palate related velopharyngeal insufficiency (VPI) incurs increased surgical complications or compromises speech outcomes. DESIGN: A retrospective review of patients who had Furlow palatoplasty and the outcomes of surgery in the treatment of cleft palate related VPI. SETTING: A single academic center between January 2015 and January 2022. PARTICIPANTS: Patients with submucous cleft (SMC) palate or patients with prior straight line primary palatoplasty presenting with VPI. INTERVENTIONS: Simultaneous conversion Furlow palatoplasty and tonsillectomy. MAIN OUTCOME MEASURE(S): Primary outcome measures include preoperative and postoperative Modified Pittsburgh Weighted Speech Scale (mPWSS), and postoperative surgical complications. RESULTS: Eight patients (25%) underwent Furlow palatoplasty and concomitant tonsillectomy, while 24 patients (75%) underwent Furlow palatoplasty alone. A significantly lower median postoperative mPWSS score, corresponding to better velopharyngeal function, was reported for patients in the Furlow-tonsillectomy group (0, IQR 0-0) compared to the Furlow only group (1, IQR 0-9, p = 0.046). No surgical complications were encountered in either group. Five patients (20.8%) in the Furlow only group required subsequent surgery for persistent VPI. No patients in the Furlow-tonsillectomy group required additional surgical treatment for VPI (0%, p = 0.16). CONCLUSIONS: Tonsillectomy at time of Furlow palatoplasty is utilized in patients with both VPI and baseline tonsillar hypertrophy to lessen the risk of postoperative obstructive breathing. Tonsillectomy performed concurrently with Furlow palatoplasty is safe, without increased risk of surgical complications, and does not compromise post-Furlow palatoplasty speech outcomes.

Reconstruction of full thickness lower eyelid defects using a lateral advancement flap with Z-plasty and periosteal strip.

PURPOSE: To describe a single stage technique of reconstruction of full thickness lower eyelid defects using a lateral advancement flap and Z-plasty combined with a lateral periosteal strip. METHODS: A retrospective case series of six patients who underwent reconstruction using this technique is presented documenting surgical technique, clinical photographs and postoperative outcomes. RESULTS: All six patients demonstrated good eyelid position and cosmesis following reconstruction. CONCLUSION: A lateral advancement flap with Z-plasty combined with a periosteal strip is an effective technique to close lower eyelid defects of up to eighty percent of eyelid width, providing a good structural and aesthetic outcome.

Hybrid Palatoplasty: A Simplified DOZ (Double Opposing Z Plasty) with Palatal Myoplasty for Primary Palate Repair.

Introduction Surgical techniques for soft palate repair aiming for zero velopharyngeal insufficiency (VPI) are still not achieved. Straight line closure of the soft palate by various techniques of intravelar veloplasty (IVVP) leads to higher incidence of VPI due to scar contracture. Furlow's Z plasty has long, narrow, thin mucosal flaps and mucomuscular flaps with malaligned muscle closure. We present a technique of "hybrid palatoplasty" which borrows from and adds to the existing methods, is robust, is easy to replicate, and results in normal speech consistently. Aim (1) To design a technique of "hybrid palatoplasty"-combining double opposing Z (DOZ) plasty and IVVP, which is applicable to all types of cleft palate. (2) To evaluate the results of cleft palate children operated using the technique of "hybrid palatoplasty" from 2014 to 2015 in terms of surgical complications (fistulae and dehiscence) and incidence of VPI. Methods Our procedure combines aspects of both DOZ and IVVP. It is simplified with design of smaller Z plasties. On one side, from the oral Z plasty muscle is dissected off and sutured to the nasal mucomuscular flap of the opposite side to complete the palatal sling. Oral Z plasty is purely mucosal and reverse of the nasal side. A total of 123 cases, operated below 5 years of age were followed up. Speech was assessed by direct evaluation and tele-evaluation. Results A total of 123 cases, below 5 years of age, were operated between 2014 and 2016 with at least 5 years of follow-up. Note that 120 had normal speech, and 3 had VPI of which 2 were subsequently corrected and went on to develop normal speech. Conclusion This novel "hybrid palatoplasty" is a simple technique with good speech outcome as it combines the principles of Z plasty and direct muscle repair with palatal sling formation.

Use of single-layer artificial dermal template in patients with trauma and burns.

OBJECTIVE: Artificial dermal templates (ADTs), were designed initially to provide extracellular matrix and skin substitute for extensive burn injuries. Use of ADTs in a variety of other indications, has also been described in the literature. In this study, we describe our experience of using ADTs for different indications in burn contractures and wound coverage. METHOD: In this retrospective study, patients requiring burn scar contracture release, permanent wound coverage for acute traumatic wounds and temporary wound coverage to prepare for complex reconstructions, and where the ADT Pelnac (Gunze Ltd., Japan) was applied, were evaluated. Data regarding patient sex, age, type and location of injury, comorbidities, operations and complications were recorded. RESULTS: A total of 24 patients were included in the study, of whom 12 patients were operated on for burn contractures. ADTs were used with split-thickness skin grafts (STSGs) or Z-plasties in a single-stage procedure. In six patients, ADT and STSGs were used to cover defects with exposed bone or tendon. Of the patients, six had their wounds covered temporarily while they were stabilised for complex reconstructions or were awaiting definitive histopathological results. Revisional surgeries due to graft failures or insufficient contracture releases were required by 12 patients. All temporary wound coverage patients had successful flap reconstructions after stabilisation of their general status, had tumour-free margins in the histopathological examination, and no necrosis or infection was seen on follow-up. CONCLUSION: In this study, ADTs had positive effects on selected patients, but comprehensive and comparative clinical studies are needed for different indications to choose between these templates.

Retro-Malleolar Z-Plasty of Flexor Hallucis Longus Tendon in Post-Traumatic Checkrein Deformity: A Case Series and Literature Review.

Checkrein deformity (CD) is a dynamic deformity of the hallux characterized by flexion contracture of the interphalangeal (IF) joint and extension contracture of the metatarsophalangeal (MTP) joint, worsened by ankle dorsiflexion. It is due to post-traumatic or ischemic retraction of the long hallux flexor tendon (FHL) following soft tissue trauma, leg fractures, ankle fractures and, more rarely, calcaneal or talar fractures. Diagnosis is essentially clinical, associated with imaging, to rule out unrecognized causes and evaluate fracture healing process. Few cases are reported in literature without univocal treatment. Background and Objectives: To analyze clinical and functional outcomes in patients with CD treated with release and retro-malleolar Z-plasty lengthening of FHL tendon. Materials and Methods: Patients diagnosed with CD treated with retro-malleolar (at tarsal tunnel) Z-plasty lengthening of the FHL tendon between January 2016 and August 2020 were included. Clinical and functional outcomes were collected on admission and post-surgery and analysed retrospectively. Patients with a minimum follow-up of 18 months were included. Results: A total of 14 patients, with mean age of 37.4 years old, with CD diagnosis were included in the study. All patients were suffering from post-traumatic CD and the mean time from trauma to onset of deformity was of 7 months (range 1−12). At a mean follow-up of 31.8 months (range 18−48) we found a significant improvement (p < 0.05) in terms of pain relief (VAS), function (AOFAS score) and ROM of the IP and MTP hallux joints. No recurrence, loss of strength, nerve injury or tarsal tunnel syndrome were observed. No patient required revision surgery. Conclusions: In this case series the retro-malleolar FHL tendon Z-plasty proved to be a suitable option for CD correction, allowing a good clinical and functional recovery.

Overlapping repair and epitenon healing are more stable biomechanically than side to side repair and endotenon healing in achilles tendon lengthening with Z plasty.

BACKGROUND: The current study aimed to compare biomechanical stability and healing process of side-to-side repair with overlapping repair after Achilles tendon lengthening with Z-plasty. METHODS: In our study, 22 Sprague Dawley male rats were used. Side-to-side repairs were classified as group 1 and overlapping repairs as group 2. The left and right legs of seven rats were used to compare early group 1 and early group 2 biomechanical test results at day 0. Seven rats were used to compare late group 1 and late group 2 biomechanical test results at day 28. Both the right and left tendons were tested from the four rats examined in the biomechanically in the untreated control group. The last remaining four rats were used for histopathological evaluation of tendon repair, at 28-days from the index procedure.The ultimate load to failure was compared between groups. RESULTS: At time 0, there were no measurable differences between group 1 (3.8 ± 1.4 N) and group 2 (3.7 ± 1.1 N), and both could endure less than one-tenth of the untreated control (49 ± 12). At 28 days, ultimate load to failure improved significantly in both group 1 (16.2 ± 3.5 N) and even more in group 2 (36 ± 8.1 N). While there was a significant difference between group 1 and group 2, neither were able to meet the untreated control (49 ± 12). Histopathological evaluation in the post-healing period showed that fibrosis, neovascularization, and inflammation increased in both groups. CONCLUSION: The overlapping suture technique and epitenon healing have more stability compared to side-to-side suture technique and endotenon healing. Human population trials may or may not exist, our study suggests it should be considered and further investigation needed before actual clinical application.

Humero-Pectoral Band in Poland Syndrome.

The humero-pectoral band in Poland syndrome is a rare presentation and needs urgent surgery because it restricts the shoulder abduction of the patient. In our case, instead of excising the band, we have made use of the tissue by including it in the Z-plasty flaps which make the flaps reliable even though they were supplied by a narrow base.

The Z-plasty contributes to the coalescence of a chronic non-healing wound.

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.

Comparative analysis on the effect of Z-plasty versus conventional simple excision for the treatment of sacrococcygeal pilonidal sinus: A retrospective randomised clinical study.

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.

Arthroscopic versus open release of internal rotation contracture in the obstetrical brachial plexus paralysis (OBPP) sequela.

BACKGROUND: Latissimus dorsi (LD) and teres major (TM) tendon transfers are effective surgical procedures to improve shoulder abduction and external rotation for children with obstetrical brachial plexus palsy (OBPP). Open pectoralis major (PM) tendon Z-plasty and arthroscopic subscapularis (SS) release are 2 options for the release of internal rotation contractures to enhance muscle transfers. This study compared the functional results of LD and TM tendon transfers with open PM tendon Z-plasty or arthroscopic SS release. METHODS: The study included 24 patients who underwent LD and TM tendon transfers for OBPP (9 arthroscopic SS release, 15 open PM tendon Z-plasty) with a mean follow-up of 41.33 months (range, 36-60 months) and 47.2 months (range, 36-60 months), respectively. Functional evaluation was made according to range of motion and Mallet scoring system. RESULTS: Shoulder abduction-external rotation degrees and scores in all sections of the Mallet scoring system significantly increased in both groups (P < .001). Postoperatively, the arthroscopic SS release group had significantly better abduction degrees (P = .003), total Mallet scores (P < .001), and superior abduction (P = .043), active external rotation (P = .043), hand-to-head (P = .043), and hand-to-mouth (P < .001) scores for the Mallet scoring system. DISCUSSION: Transfer of LD together with TM tendons combined with one of the internal rotation contracture release procedures yielded good clinical and functional results in patients younger than age 7, regardless of the type of release method. However, arthroscopic SS release, although requiring an experienced surgeon, revealed better clinical and functional outcomes and is considered to be a less invasive and superior method.

Total Hip Arthroplasty in Ankylosing Spondylitis With Extension Contracture of Hips.

BACKGROUND: Despite significant pain relief following total hip arthroplasty (THA) in patients with ankylosing spondylitis, a small subset of patients presenting with extra-articular extension contracture of hips remains unsatisfied. METHODS: We retrospectively evaluated the patients with ankylosing spondylitis who underwent simultaneous bilateral THA and had extensor tightness of both hips preoperatively. They were managed with modified Z-plasty of iliotibial band. Patients with windswept deformity, commonly seen in bilateral hip arthritis caused by ankylosing spondylitis, were excluded. RESULTS: Between July 2011 and June 2015, out of 148 patients with bilateral hip involvement, 10 patients (20 hips) had extension contracture of both hips that was addressed during surgery. All patients were followed up for a minimum of 2 years. They could sit comfortably on a chair of height 18 inches with hips and knees flexed to at least 90°. The mean postoperative sum range of motion was 144.6° with an average hip flexion of 95° (range, 90°-105°). None of them had recurrence of extension contracture. There was significant improvement in range of motion and hence ambulation and function. No radiolucent lines exceeding 2 mm were seen in any of the zones around either of the components as evaluated in latest X-rays. CONCLUSION: Extension contracture of hip although rare is a noticeable problem and needs to be addressed during THA. Modified Z-plasty technique of iliotibial band is a reliable method in managing these patients.

Surgical Treatment for Palatoglossal Arch Cicatrix and Velopharyngeal Insufficiency After Adenotonsillectomy.

Postadenotonsillectomy velopharyngeal incompetence/insufficiency/dysfunction (VPI) is an uncommon but potentially surgically challenging problem. We report a child without cleft palate who developed severe palatoglossal arch cicatrix and VPI after adenotonsillectomy, and describe bilateral palatoglossal arch z-plasty to restore palatal function and speech.

Palatal Measurements Pre- and Post-Furlow Cleft Palate Repair: Analysis of Palatal Lengthening and Comparison Within Cleft Types.

OBJECTIVE: The purpose of this study was to characterize intraoperative palatal lengthening with the modified Furlow cleft palatal repair and to determine whether lengthening correlated with preoperative cleft width, cleft type, or operating surgeon. DESIGN: Retrospective study. SETTING: Academic tertiary care pediatric hospital. PATIENTS: One hundred eighty pediatric patients undergoing primary or secondary palatoplasty using the Furlow technique. INTERVENTIONS: Cleft and palatal lengths and widths were measured pre- and post-Furlow cleft palatal repair. MAIN OUTCOME MEASURES: Immediate postoperative percentage change in surface palate length, straight palate length, and soft palate length. RESULTS: The average cleft widest width and width at the hard-soft palate junction were 10.2 and 9.5 mm, respectively, and varied with Veau cleft type. Following Furlow palatoplasty, lengths of the curved, straight, and soft palate increased by 7.5%, 15.8%, and 30.6%, respectively. Degree of palatal lengthening varied among surgeons and Veau cleft type but was not related to cleft width. Seven (4.0%) patients developed postoperative oronasal fistulas. Patients with a Veau IV cleft and larger cleft widths were at an increased risk for fistula formation. CONCLUSIONS: This study demonstrates that overall palatal lengthening occurs with the modified Furlow technique. Long-term follow-up studies are needed to determine the clinical relevance of these findings.

Achilles Lengthening and Multiple Z-Plasty in Parallel for Correction of Toe Walking Associated With Burn Scar Equinus Contracture.

The literature is sparse regarding treatment of burn scar equinus contracture, with focus primarily on staged procedures, serial casting, and gradual correction using external fixation in combination with soft-tissue procedures. This case study describes a single-stage ambulatory approach for late-stage correction of burn scar equinus contracture associated with toe walking. A case report is presented of an 11-year-old male with focus on procedure selection, surgical technique, and 12-month follow-up results. Surgery involved a single-stage approach with open Achilles lengthening, in addition to multiple skin Z-plasty in parallel with immediate protected weightbearing to correct toe walking. Inadequate release of contracture was noted intraoperatively after Achilles lengthening. Full correction was achieved after converting the longitudinal incision into multiple Z-plasty in parallel, with full heel purchase at 2 weeks postoperatively. The patient was completely healed with pain-free range of motion at 6 weeks postoperatively. At 12 months postoperatively, he continued to ambulate normally without overcorrection or recurrence of deformity. This case study describes a late-stage, minimally invasive, single-stage approach to correction of burn scar equinus contracture. The surgical principles and technique are described. Allowance of immediate weightbearing was possible because all other burn wounds were healed at late-stage presentation that avoided the need for gradual correction with external fixation or serial procedures.
