Overlapping Intravelar Veloplasty Improves the Speech Outcomes in Submucous Cleft Palate.

BACKGROUND: Submucous cleft palate (SMCP) is a subgroup of cleft palate that can present as velopharyngeal insufficiency due to muscle displacement. The pharyngeal flap and Furlow palatoplasty have been introduced to correct SMCP patient with velopharyngeal insufficiency. However, pharyngeal flap and Furlow palatoplasty can occur various complications. We consider the overlapping intravelar veloplasty (IVVP) can overcome these complications. Therefore, we present the speech outcomes of overlapping IVVP for the treatment of patients with SMCP. METHODS: We retrospectively reviewed 12 patients with SMCP underwent overlapping IVVP between April 2016 and October 2018. The patients who underwent speech evaluation, nasometry, and nasoendoscopy before and after surgery and who were followed up for >18 months were enrolled in this study. RESULTS: The average age of the patients was 5 years (range, 3-11 years) and the postoperative follow-up period ranged from 18 to 24 months (mean, 20 months). The preoperative perceptual speech evaluation was moderate and the postoperative evaluation was normal ( P < 0.01). The preoperative and postoperative nasalance scores obtained using a nasometer were 37.00 and 12.50, respectively, ( P < 0.01). Preoperative and postoperative velopharyngeal movements were grades 3 and 0, respectively, ( P < 0.01). CONCLUSIONS: Our study showed that overlapping IVVP could provide successful correction of velopharyngeal insufficiency in patients with SMCP, including relatively old patients.

Efficacy of Wheelchair Skills Training Program in Enhancing Sitting Balance and Pulmonary Function in Chronic Tetraplegic Patients: A Randomized Controlled Study.

Background and Objectives: This study aimed to evaluate the effectiveness of a wheelchair skills training program (WSTP) in improving sitting balance and pulmonary function in patients with chronic tetraplegia resulting from cervical spinal cord injury (cSCI). Materials and Methods: Twenty-four patients were randomly divided into WSTP and control groups. The WSTP group participated in the WSTP for eight weeks, while the control group underwent conventional physical therapy for the same eight-week period. Sitting balance was evaluated using the activity-based balance level evaluation (ABLE) scale, and pulmonary function was evaluated using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). Results: The WSTP group showed significant improvements in both sitting balance and pulmonary function during the intervention period (p < 0.05), whereas the control group did not show any significant changes. A strong positive correlation was found between ABLE scores and all three pulmonary function parameters across all time points. Conclusions: Our results suggest that the WSTP significantly improves sitting balance and specific aspects of lung function in patients with tetraplegia.

Effectiveness of Absorbable Plates for the Treatment of Nasal Septal Cartilage Fractures.

BACKGROUND: Nasal bone fractures are the most common type of facial fracture. Nasal bone fractures often occur in combination with septal cartilage fractures, because the nasal septal cartilage acts as a vertical strut and provides structural support for the nose and bilateral nasal airway. However, the treatment for nasal septal cartilage fracture remains controversial, and if untreated, nasal septal cartilage fracture can lead to various complications, such as nasal obstruction and posttraumatic nasal and septal deformity. This study aimed to evaluate the effectiveness and safety of our procedure in which septal cartilage fractures were treated with septoplasty using an absorbable plate as an internal splint. METHODS: Between January 2017 and November 2020, 21 patients with nasal septal cartilage fractures were treated with septoplasty using an absorbable plate as an internal splint. The severity of the septal cartilage fracture was graded from 0 to 3 according to the computed tomography septal grading system. The numeric graded scale of nasal septal cartilage fracture was evaluated preoperatively and 6 months postoperatively using a computed tomography scan. RESULTS: Of 21 patients with septal cartilage fractures, 12 were treated with a polycaprolactone (PCL) mesh plate, and 9 were treated with a polydioxanone (PDS) plate. In the PDS plate group, the preoperative numeric scale of nasal septal cartilage fracture was 2.50 (2.00-3.00), whereas the postoperative numeric scale was 1.00 (1.00-1.25, P = 0.023). In the PCL mesh plate group, the preoperative numeric scale of nasal septal cartilage fracture was 2.00 (2.00-3.00), whereas the postoperative numeric scale was 1.00 (1.00-1.50, P = 0.034). The effectiveness of the PCL mesh plate and that of the PDS plate group according to the septal grading scale were 1.45 (SD, 0.522) and 1.18 (SD, 0.603), respectively. However, these differences were not statistically significant. CONCLUSIONS: Our study shows that septoplasty using absorbable plates provides satisfactory and safe clinical outcomes in patients with nasal septal cartilage fractures.

Speech Outcomes of Treatment for Velopharyngeal Insufficiency: Combined Use of an Overlapping Intravelar Veloplasty and Dynamic Sphincter Pharyngoplasty.

BACKGROUND: Velopharyngeal insufficiency involving a large velopharyngeal gap and poor lateral wall movement is referred to as a "black hole" and remains a challenging problem for cleft surgeons. The effect of the pharyngeal flap on this form of velopharyngeal insufficiency is still debatable because a wide pharyngeal flap is associated with a high incidence of airway obstruction. The present study aimed to evaluate the speech outcomes of combined overlapping intravelar veloplasty and dynamic sphincter pharyngoplasty for the treatment of velopharyngeal insufficiency. METHODS: Between March 2016 and June 2019, 15 patients with velopharyngeal insufficiency were treated with a combination of overlapping intravelar veloplasty and dynamic sphincter pharyngoplasty. Preoperative speech evaluation was performed on the basis of perceptual speech evaluation, nasometry, and nasoendoscopy. Postoperative speech evaluation using the same approach as that used preoperatively was performed after completion of speech therapy. RESULTS: All 15 patients achieved satisfactory velopharyngeal port closure and speech phonation after completion of speech therapy. No additional procedures were performed to improve velopharyngeal port closure and speech production. The preoperative and postoperative results of perceptual speech evaluation, nasometry, and nasoendoscopy evaluation were significantly different (P < 0.01). CONCLUSION: Combined treatment with overlapping intravelar veloplasty and dynamic sphincter pharyngoplasty can correct the velopharyngeal insufficiency "black hole" with highly reliable results and minimal risk of airway obstruction.

Medial Epicanthoplasty With the Classic and Modified Skin Redraping Method: A Retrospective Case Control Study.

ABSTRACT: The skin redraping method for medial epicanthoplasty is characterized by some shortcomings which warrants modification. In this study, clinical data of 193 patients who underwent medial epichanthoplasty by the modified skin redraping technique or the classic skin redraping technique were reviewed retrospectively. The patients underwent operation between May 2018 and June 2020 and were followed up for not less than 6 months. Interepicanthal distance, interpupillary distance, patient satisfaction, and postoperative complications were evaluated. In terms of interepicanthal distance/inter-pupillary distance ratio ( P > 0.05) and satisfaction score ( P = 0.759), the modified skin redraping technique and the classic skin redraping technique were similar. In the classic skin redraping group, there were 3 cases of visible scarring in the lower eyelid, corresponding to significantly more cases than in the modified skin redraping group (n = 0, P < 0.001). There were more out-fold cases in the modified skin redraping group (76/90) than in the classic skin redraping group (17/88) ( P < 0.001). Utilizing the modified skin redraping medial epicanthoplasty can prevent medial hooding of the upper eyelid, reduce the probability of visible scarring, and produce more out-fold with concurrent double eyelidplasty compared with classic skin redraping epicanthoplasty. Level of evidence: IV.

Comparison of Effectiveness and Safety of a Botulinum Toxin Monotherapy and a Combination Therapy with Hyaluronic Acid Filler for Improving Glabellar Frown.

BACKGROUND: Among numerous cosmetic procedures for face rejuvenation performed all over the world, botulinum toxin type A (BoNT-A) for wrinkles is one of the most widely practiced procedures. However, for severe frowns, the application of botulinum toxin is often insufficient. In this study, the effects of hyaluronic acid filler combination therapy and the BoNT-A alone were evaluated. METHODS: Forty subjects with 2 or higher points (moderate to severe) of a facial wrinkle scale (FWS) when frowning in the glabellar area were assigned to 2 group: Botulinum toxin type A monotherapy group and a combination regimen of the toxin and hyaluronic acid filler group. Subjects visited outpatient department every 4 weeks until 28 weeks after the injection, and the assessment of the efficacy using FWS, subject satisfaction at both resting and maximum frowning and safety analysis were performed. RESULTS: Subjects of both group was administered 18U of BoNT-A and the subjects of the combination group received additional 0.45mL of hyaluronic acid filler regimen. Both at rest and maximum frown, the combination group scored lower FWS than the toxin and showed significance in the week-20 and week-28. And at final visit, subject satisfaction score of the combination was higher than that of toxin group. CONCLUSION: For patients with moderate to severe glabellar frown, the combined administration of BoNT-A and hyaluronic acid filler could be a considerable treatment for improving wrinkles.

"Fasting: An Effective Preconditioning Method to Increase Fat Graft Survival".

BACKGROUND: Most preconditioning techniques before fat grafting require external manipulation. Since nutrition is the main factor maintaining the balance of lipogenesis and lipolysis, we hypothesized that fasting before undergoing autologous fat grafting may increase lipolysis and reduce adipocyte size, thereby improving the fat graft survival rate. METHODS: C57BL/6 mice were divided into 24 h starved or fed groups. Adipose tissue lipolysis, adipogenesis, and angiogenesis-related gene expression, in fat from both groups, were analyzed. The volume and weight of the grafted fat at 4-8 weeks postoperatively were measured using micro-computed tomography. Immunohistochemistry staining and mRNA expression analysis were also performed to evaluate the effect of fasting on fat graft survival. RESULTS: Fasting decreased adipocyte size by inducing adipose tissue lipolysis. Adipogenesis-related genes were remarkably downregulated while lipolysis-related genes and angiogenesis inducer genes were significantly upregulated in the starved adipose tissue. The mice grafted with the fat from the 24 h starved group had approximately 20% larger volumes and considerably heavier weights than those from the fed group. Increased viable adipocytes and vessels, and reduced macrophages in the fat grafts obtained from the 24 h starved group were also observed. CONCLUSIONS: Fasting for 24 h before harvesting fat increased the retention volume of fat graft by increasing angiogenesis via VEGF induction. Therefore, fasting would be a novel and reliable preconditioning strategy to improve graft survival in autologous fat grafting.

Nasal Reconstruction of a Frontonasal Dysplasia via Septal L-Strut Reconstruction Using Costal Cartilage.

OBJECTIVE: Frontonasal dysplasia (FND) is a rare congenital condition. Its major features include hypertelorism, a large and bifid nasal tip, and a broad nasal root. We present our technique of septal L-strut reconstruction using costal cartilage. DESIGN: Retrospective review from June 2008 and August 2017. METHODS: Under general anesthesia, 6 patients with FND underwent septal reconstruction using costal cartilage via open rhinoplasty. We reconstructed the nasal and septal cartilaginous framework by placing columellar struts and cantilever-type grafts. RESULTS: The patients ranged in age from 6 to 13 years old. All were female. The follow-up period ranged from 8 months to 2 years; we encountered no postoperative complications (infection, nasal obstruction, or recurrence). All patients were satisfied with their nasal appearance. CONCLUSIONS: Although the results were not entirely satisfactory from an esthetic point of view, we found that FND can be treated via septal reconstruction with costal cartilage and that the clinical outcomes are reliable and satisfactory. Our approach is a useful option for FND patients.

Effects of Visual Cue Deprivation Balance Training with Head Control on Balance and Gait Function in Stroke Patients.

Background and Objectives: Visual cue deprivation is the instability of head control is increased. The purpose of this study is to investigate the effects of visual cue deprivation balance training by applying head control feedback to the balance and gait ability of stroke patients. Materials and Methods: The study was conducted on 41 patients diagnosed with hemiplegia due to stroke. Subjects were randomly assigned to any of the following groups: the experimental group I, the experimental group II or the control group. The randomization method used a simple randomization method. To evaluate changes in balance function, a LOS (Limit of Stability) and a BBS (Berg Balance Scale) were performed. In addition, to evaluate changes in ST (stride time), SL (stride length), and cadence, a LEGSys were performed. Results: A two-way repeated ANOVA was conducted to analyze the differences between groups. There were significant differences between groups in all variables for the balance function. There were significant differences between groups in all variables for the balance function. There were significant differences between groups in SL and cadence for the gait function. Conclusions: Visual cue deprivation balance training applying head control feedback is effective in improving dynamic balance ability and cadence. It is necessary to constantly maintain the head orientation by feedback and to properly control the head movement.

The Effectiveness of Early Combined CO2 Ablative Fractional Laser and 595-nm Pulsed Dye Laser Treatment After Scar Revision.

ABSTRACT: Scars are significant complications of wound healing and associated with negative physical, psychological, and cosmetic effects. Scar revision and laser treatment have been used over the past century to improve many different types of scars. Here, we evaluated the effectiveness of early combined carbon dioxide ablative fractional laser (AFL) and pulsed dye laser (PDL) treatment after scar revision. Fourteen patients who underwent scar revision were enrolled. All patients were treated with both a 10,600-nm AFL and a 595-nm PDL commencing 2 weeks after scar revision and continuing at 4-week intervals for a total of 4 treatments. Vancouver Scar Scale scores were evaluated before treatment and 5 months after the final treatment. All Vancouver Scar Scale scores improved significantly except that of scar height. We encountered no adverse complications (wound disruption, or hyper- or hypopigmentation) during follow-up. Early combined carbon dioxide AFL and PDL treatment after scar revision effectively and safely minimized scar formation.

The Effects of Alar Base Augmentation in Secondary Unilateral Cleft Lip Nasal Deformity.

ABSTRACT: In unilateral cleft lip and palate patients, the alar base is displaced inferoposterolaterally due to the depression of the pyriform aperture in the cleft side, and the drooping of the nostril rim is provoked by displacement of the alar base. This study was conducted between May 1998 and December 2012. In total, 82 patients with secondary unilateral cleft lip nasal deformities were treated using alar base augmentation. The patients were divided into two groups according to the degree of their preoperative alar base asymmetry. Patients with alar base asymmetry <3 mm were treated with a soft tissue augmentation procedure. Those with alar base asymmetry >3 and <6 mm were treated with a bony augmentation procedure. Soft tissue augmentation was conducted in 42 patients, and bony augmentation was conducted in 40 patients. In the soft tissue augmentation group, the degree of alar base asymmetry was improved from 2.42 ±â€Š0.38 mm preoperatively to 0.45 ±â€Š0.21 mm postoperatively (P  < 0.05). In the bony augmentation group, the degree of alar base asymmetry was improved from 4.33 ±â€Š0.50 mm preoperatively to 0.81 ±â€Š0.20 mm postoperatively (P  < 0.05). In the amount of alar base augmentation, there were statistically significant differences between the soft tissue augmentation group and the bony augmentation group (P  < 0.05). This clinical study shows that secondary cleft lip nasal deformities can be corrected with alar base augmentation using soft tissue and bony augmentation and that these procedures can provide reliable, satisfactory, and safe clinical outcomes.

Ameliorating Fibrotic Phenotypes of Keloid Dermal Fibroblasts through an Epidermal Growth Factor-Mediated Extracellular Matrix Remodeling.

Keloid and hypertrophic scars are skin fibrosis-associated disorders that exhibit an uncontrollable proliferation of fibroblasts and their subsequent contribution to the excessive accumulation of extracellular matrix (ECM) in the dermis. In this study, to elucidate the underlying mechanisms, we investigated the pivotal roles of epidermal growth factor (EGF) in modulating fibrotic phenotypes of keloid and hypertrophic dermal fibroblasts. Our initial findings revealed the molecular signatures of keloid dermal fibroblasts and showed the highest degree of skin fibrosis markers, ECM remodeling, anabolic collagen-cross-linking enzymes, such as lysyl oxidase (LOX) and four LOX-like family enzymes, migration ability, and cell-matrix traction force, at cell-matrix interfaces. Furthermore, we observed significant EGF-mediated downregulation of anabolic collagen-cross-linking enzymes, resulting in amelioration of fibrotic phenotypes and a decrease in cell motility measured according to the cell-matrix traction force. These findings offer insight into the important roles of EGF-mediated cell-matrix interactions at the cell-matrix interface, as well as ECM remodeling. Furthermore, the results suggest their contribution to the reduction of fibrotic phenotypes in keloid dermal fibroblasts, which could lead to the development of therapeutic modalities to prevent or reduce scar tissue formation.

Volumetric Evaluation of Dead Space in Ischial Pressure Injuries Using Magnetic Resonance Imaging: A Case Series.

OBJECTIVE: To establish a preoperative evaluation procedure by measuring the volume of dead space using MRI in patients with ischial pressure injuries. METHODS: Patients with spinal cord injury and ischial pressure injuries who underwent treatment between August 2016 and November 2019 were included in the study. Preoperative MRI scan was conducted on all patients. The volume estimation and three-dimensional (3D) reconstruction were performed based on MRI data using a 3D Slicer. Based on the resulting volume, a muscle flap that could fit the dead space was selected. Surgery was performed with the selected muscle flap, and a fasciocutaneous flap was added, if necessary. RESULTS: A total of eight patients with ischial pressure injuries were included in the study. The mean patient age was 59.0 ± 11.0 years. The mean body mass index was 26.62 ± 3.89 kg/m2. The mean volume of dead space was 104.75 ± 81.05 cm3. The gracilis muscle was the most selected muscle flap and was used in four patients. In five of eight cases, a fasciocutaneous flap was used as well. The mean follow-up period was 16 months, and by that point, none of the patients evinced complications that required surgery. CONCLUSIONS: To the authors' knowledge, this is the first report on volumetric evaluation of dead space in ischial pressure injuries. The authors believe that the 3D reconstruction process would enable adequate dead space obliteration in ischial pressure injuries. The authors propose that preoperative MRI scans in patients with ischial pressure injury should become an essential part of the process.

A comparative study of intraoral versus retromandibular approach in the management of subcondylar fracture.

BACKGROUND: The purpose of this study was to compare the outcomes and effectiveness between intraoral approach and retromandibular approach for treatment of subcondylar fracture of mandible. METHODS: Between March 2011 and October 2013, 24 patients with subcondylar fractures of the mandible were treated by a single surgeon with an intraoral approach using an angulated screwdriver (n = 14) or by another surgeon using a retromandibular approach (n = 10). The interincisal distance was measured 1 week (T0), 6 weeks (T1), 3 months (T2), and 6 months (T3) postoperatively. We also compare the average operation time and the cost of operation between the two groups. RESULTS: At 6 months postoperatively, all 24 patients achieved satisfactory ranges of temporomandibular joint movement, with an interincisal distance > 40 mm without deviation and with stable centric occlusion. The intraoral group had the median interincisal distance of 14 mm at T0, 38 mm at T1, 42.5 mm at T2, and 43 mm at T3, while the retromandibular group had that of 15, 29, 35, and 42.5 mm respectively. There was no statistically significant difference between the intraoral and the retromandibular group at T0 and T4. However, significant differences were noted T1 and T2 (p < 0.01). The differences of average operation time between the intraoral (81 min) and retromandibular group (45 min) were statistically significant (p < 0.01). The cost of an operation was 369.96 ± 8.14 (United States dollar [USD]) in intraoral group and was 345.48 ± 0.0 (USD) in retromandibular group. The differences between the two groups were statistically significant (p < 0.01). CONCLUSION: In open reduction of a subcondylar fracture of the mandible, a intraoral approach using an angulated screwdriver is superior to the retromandibular approach in terms of interincisal distance, although the operation time is longer.

Surgical Treatment of Mandible Fracture Using Unsintered Hydroxyapatite/Poly L-Lactide Composite Fixation System.

Recently, absorbable plates have been used for various types of facial fractures. However, in the case of mandibular fractures, a large amount of force is applied after fixation. Thus, a firm fixation is necessary. In particular, unfavorable fractures are more frequent in mandibular fractures. Therefore, plates should be strong enough to withstand forces at the time of surgery. The purpose of this study was to determine clinical efficacy and usefulness of unsintered hydroxyapatite (u-HA)/poly (L-lactide) (PLLA) composite system by clinical application and follow-up of fixation in patients with mandible fracture. A total of 13 patients with mandible fractures were assessed for compliance with the selection criteria. Fracture site was confirmed with radiographic findings including X-ray and facial computed tomography images. Subjects who fulfilled all criteria underwent operation using HA/PLLA composite fixation system (OSTEOTRANS; Takiron Co Ltd, Osaka, Japan). After reduction of fracture site through oral or skin incision, we placed OSTEOTRANS plates on fracture line and performed rigid fixation with OSTEOTRANS-MX screws. Follow-up was performed at 1 week, 1, 3, and 6 months after surgery. Occlusion and mouth opening were checked by physical examination and radiographic finding. We also confirmed bone approximation status, bony gap change, and bone union status. All patients finished every follow-up. They were satisfied with outcomes without complications such as malocclusion, foreign body sensation, or tenderness. This study confirms that OSTEOTRANS can be used appropriately for mandibular fractures.

The effects of platelet-rich plasma on hypertrophic scars fibroblasts.

We hypothesised that a feedback mechanism of the transforming growth factor (TGF)-ß1 signalling pathway, triggered by high-level TGF-ß1, activates platelet-rich plasma (PRP) release to reduce connective tissue growth factor (CTGF) production and expression of CTGF mRNA in hypertrophic scar dermal fibroblasts. Primary dermal fibroblasts were isolated from cultures of hypertrophic scars. Cells were cultured after addition of serum-free Dulbecco's modified Eagle's medium supplemented with 5% (wt/vol) PRP or platelet-poor plasma (PPP). At 1, 4, 6, 8, 11, and 13 days after addition of PRP or PPP, the TGF-ß1 and CTGF levels in supernatants were determined using solid-phase enzyme-linked immunosorbent assays. Quantitative reverse transcription polymerase chain reactions were performed to quantify TGF-ß1 and CTGF mRNA expression levels. TGF-ß1 mRNA expression in the PRP groups was lower than in the PPP groups from 4 to 13 days of culture, and there was statistically significant difference (P < .01). CTGF level and mRNA expression in the PRP groups was lower than in the PPP groups, and there were statistically significant differences (P < .01). Although further experiments will focus on clarifying the second messenger of the TGF-ß1 negative feedback mechanism, the in vitro data presented show that PRP can potentially reduce CTGF and CTGF gene transcription by triggering the TGF-ß1 signalling negative feedback mechanism.

Effects of visual feedback balance training on the balance and ankle instability in adult men with functional ankle instability.

[Purpose] This study examined the effects of visual feedback balance training on the balance and ankle instability in adult men with functional ankle instability. [Subjects and Methods] Twenty eight adults with functional ankle instability, divided randomly into an experimental group, which performed visual feedback balance training for 20 minutes and ankle joint exercises for 10 minutes, and a control group, which performed ankle joint exercise for 30 minutes. Exercises were completed three times a week for 8 weeks. Bio rescue was used for balance ability. It measured limit of stability at one minute. For ankle instability was measured using Cumberland ankle instability tool (CAIT). This measure was performed before and after the experiments in each group. [Results] The experimental group had significant increase in the Limit of Stability and CAIT score. The control group had significant increase in CAIT score. While the Limit of Stability increased without significance. [Conclusion] In conclusion, visual feedback balance training can be recommended as a treatment method for patients with functional ankle instability.

Clinical Application of Acellular Dermal Matrix in the Treatment of Aplasia Cutis Congenita on Scalp.

Aplasia cutis congenita (ACC), also called cutis aplasia, is a rare congenital abnormality characterized by focal defect of the skin at birth, frequently involving the scalp, but may affect any region of the body. Approximately 80% of patients have the defect confined to the skin and generally less than 2 cm diameter, which can be managed conservatively with dressing alone. However, some patients present large cutaneous defects and aplasia of the underlying skull may also be present. The main complications of large defects include meningeal infection, bleeding, and thrombosis, which may be deadly. Some controversy remains in the literature regarding ACC treatment, with surgical and conservative treatment modalities having proponents and opponents.This article presents the first case of a newborn with full-thickness ACC lesion of the vertex healed by conservative treatment with application of acellular dermal matrix.

The effects of a multisensory dynamic balance training on the thickness of lower limb muscles in ultrasonography in children with spastic diplegic cerebral palsy.

[Purpose] This study aimed to investigate the effects of multisensory dynamic balance training on muscles thickness such as rectus femoris, anterior tibialis, medial gastrocnemius, lateral gastrocnemius in children with spastic diplegic cerebral palsy by using ultrasonography. [Subjects and Methods] Fifteen children diagnosed with spastic diplegic cerebral palsy were divided randomly into the balance training group and control group. The experimental group only received a multisensory dynamic balance training, while the control group performed general physiotherapy focused balance and muscle strengthening exercise based Neurodevelopmental treatment. Both groups had a therapy session for 30 minutes per day, three times a week for six weeks. The ultrasonographic muscle thickness were obtained in order to compare and analyze muscle thickness before and after in each group. [Result] The experimental group had significant increases in muscle thickness in the rectus femoris, tibialis anterior, medial gastrocnemius and lateral gastrocnemius muscles. The control group had significant increases in muscle thickness in the tibialis anterior. The test results of the rectus femoris, medial gastrocnemius and lateral gastrocnemius muscle thickness values between the groups showed significant differences. [Conclusion] In conclusion, a multisensory dynamic balance training can be recommended as a treatment method for patients with spastic diplegic cerebral palsy.

Real Time Navigation-Assisted Orbital Wall Reconstruction in Blowout Fractures.

BACKGROUND: Limitation in performing restoration of orbital structures is the narrow, deep, and dark surgical field, which makes it difficult to view the operative site directly. To avoid perioperative complications from this limitation, the authors have evaluated the usefulness of computer-assisted navigation techniques in surgical treatment of blowout fracture. METHODS: Total 37 patients (14 medial orbital wall fractures and 23 inferior orbital wall fractures) with facial deformities had surgical treatment under the guide of navigation system between September 2012 and January 2015. RESULTS: All 37 patients were treated successfully and safely with navigation-assisted surgery without any complications, including diplopia, retrobulbar hematoma, globe injury, implant migration, and blindness. CONCLUSIONS: Blowout fracture can be treated safely under guidance of a surgical navigation system. In orbital surgery, navigation-assisted technology could give rise to improvements in the functional and aesthetic outcome and checking the position of the instruments on the surgical site in real time, without injuring important anatomic structures.
