The Aesthetic Evaluation of the Brow-Eye Continuum After Correction of Severe Congenital Ptosis in Children With Extended Frontalis Muscle Advancement Technique.

BACKGROUND: Severe congenital ptosis is a common ocular deformity in pediatric patients that can significantly impact visual development and aesthetic appearance, leading to negative psychosocial outcomes. The frontalis muscle advancement technique is a well-established surgical treatment for severe congenital ptosis. Aesthetic changes of the brow-eye continuum often plays an important role in ptosis surgery. METHODS: We conducted a single-center retrospective case series study of patients with severe congenital ptosis who underwent the frontalis muscle advancement technique at the Department of Plastic and Reconstructive Surgery, Xijing Hospital, Fourth Military Medical University between April 2020 and June 2021. The study aimed to evaluate the aesthetic changes of the eyebrow-eyelid continuum after surgery. The main outcome measurements included marginal reflex distance 1, palpebral fissure height, eyebrow position, upper eyelid to lower eyebrow distance, lower eyelid to upper eyebrow distance, and nasal base to lower eyelid distance. RESULTS: The study included 48 patients (66 eyelids), with 30 unilateral and 18 bilateral patients. Our analysis found that eyebrow height decreased by an average of 4.8% postoperatively relative to preoperatively in all patients. CONCLUSIONS: The frontalis muscle advancement technique has demonstrated effectiveness in achieving aesthetically pleasing outcomes in children with severe ptosis. It is crucial to pay careful attention to the brow-eye continuum during the correction process, as its harmony can greatly impact the final result.

Transverse division of the rectus abdominis muscle in deep inferior epigastric perforator flap elevation: A rescue technique to include more than one perforator.

BACKGROUND: It is important to include as many perforators as possible in order to enhance the vascularity of a deep inferior epigastric perforator (DIEP) flap. However, the rectus muscle must be transected transversely, which prevents suturing and can cause a defect along the same line as the muscle-sparing procedure. When harvesting the DIEP flap, no specific method was suggested to solve these muscle defects. We found that by transecting the rectus muscle transversely, the muscle could be sutured in the tendinous area more easily while maintaining muscle function. The purpose of this study is to confirm the long-term recovery of the rectus abdominis muscle through the volume change after DIEP flap using this tendinous transection and suture method. PATIENTS AND METHODS: A retrospective review of 28 patients who underwent unilateral breast reconstruction using a DIEP flap and the tendinous transection method for multiple perforators between May 2018 and April 2020 was conducted. The preoperative and postoperative volumes of the rectus abdominis muscle were estimated both the harvest and opposite sides. RESULTS: The preoperative and postoperative muscle volumes from the harvest side were 50.08 ± 8.71 cm3 and 48.56 ± 8.61 cm3, respectively. The volume difference was 1.522 cm3 decrease, which was not statistically significant (p = .070). The preoperative and postoperative muscle volumes from the opposite side were 50.50 ± 8.15 cm3 and 50.08 ± 8.18 cm3, respectively. The volume difference was 0.434 cm3 increase and was not statistically significant (p = .064). Postoperative volume changes in the rectus muscle were not statistically significant on either side. CONCLUSION: The tendinous transection method in the DIEP flap procedure did not significantly affect postoperative rectus muscle volume. Therefore, we expect this harvest method to allow DIEP flap reconstruction that includes multiple perforators and complete donor muscle recovery.

[The grafted frontalis muscle flap: A simple and efficient lining for aesthetic reconstruction of full thickness nasal sidewall defects]. / Le lambeau du muscle frontal greffé : une technique de doublure simple et efficace dans les rhinopoïèses esthétiques transfixiantes de la face latérale du nez.

The reconstruction of thin and well-vascularized lining is capital for the aesthetic reconstruction of full thickness nasal defects. The mucosal flaps allow such reconstruction, but their dissections are difficult and not always possible, particularly for large defects of the nasal sidewall unit. The grafted frontalis muscle flap allows easily such lining reconstruction. This technique includes 3 stages, all done under local anaesthesia: 1st stage: a vertical paramedian forehead flap is classically raised and it's undersurface is full thickness skin grafted, it is then repositioned on it's site for 4 weeks; 2nd stage: this flap is raised again and split at the level of fat, just superficial to the muscle, in two flaps: the full thickness skin grafted frontalis muscle flap for the lining; and the forehead flap, without it's frontalis muscle, for the skin coverage; a sculpted cartilaginous graft is inserted between these two flaps and sutured to the lining with the aim of obtaining a symmetrical nasal sidewall and the necessary rigidity to avoid the heminasal collapse during inspiration; 3rd stage: 4 weeks after the second stage, the pedicles of these two flaps are severed. No vascular problems and no infections were seen with this technique in 11 patients operated on for evolved basal cell carcinoma of the nasal sidewall since 2018. The aesthetic results were always very satisfactory without any discomfort during breathing.

A novel ablation strategy for recurrent atrial fibrillation: Fractionated signal area in the atrial muscle ablation 1-year follow-up.

INTRODUCTION: Treatment of recurrent atrial fibrillation (AF) is sometimes challenging due to non-pulmonary vein (PV) foci. Fractionated signal area in the atrial muscle (FAAM) is a valid predictor of the location of non-PV foci. FAAM ablation has the potential to decrease the recurrence rate of atrial tachyarrhythmia in patients with recurrent AF. We compared the clinical impact of FAAM ablation for recurrent AF, using 1 year follow up date. METHODS: A total of 230 consecutive patients with symptomatic recurrent AF who underwent catheter ablation specifically targeting non-PV foci as FAAM-guided ablation (n = 113) and non-FAAM-guided ablation (n = 117) were retrospectively analyzed. FAAM was assigned a parameter (peaks slider, which indicates the number of components of fractionated signals), ranging from 1 to 15, indicating the location of the FAAM (1: largest, 15: smallest). FAAM-guided ablation was performed by ablating FAAM until none inducibility of non-PV foci. On the other hand, non-FAAM-guided ablation was performed via linear ablation, complex fractionated atrial electrogram ablation, superior vena cava isolation, and focal ablation according to the location of the non-PV foci. The RHYTHMIA system was used to perform all the procedures. The primary endpoints were AF recurrence, atrial flutter, and/or atrial tachycardia. RESULTS: After a 1-year follow up, freedom from atrial tachyarrhythmia was achieved in 90.3% and 75.2% of patients in the FAAM and non-FAAM groups, respectively (hazard ratio = 0.438 [95% confidence interval: 0.243-0.788], p = .005). CONCLUSIONS: FAAM ablation showed a promising decrease in the recurrence rate of atrial tachyarrhythmia in patients with recurrent AF during a 1-year follow-up.

Müllerotomy with anterior graded Müller muscle disinsertion for Graves upper eyelid retraction: validation of surgical outcomes using Bézier curves.

PURPOSE: To assess with Bézier curves the outcomes of Müllerotomy with anterior graded Müller muscle disinsertion for the treatment of Graves upper eyelid retraction (UER). METHODS: Eighty-six eyelids of 52 inactive GO patients operated from November 2018 to June 2021 were included in this study. All measurements were performed on Bézier curves adjusted to the upper lid contour with a previously validated algorithm. Lid contour was classified regarding grade of superposition (GS) as excellent (GS > 90%), good (GS 85-90%) or poor (< 85%). Surgical success was defined as complete or partial if postoperative grade of asymmetry was < 10% with an excellent or good lid contour, respectively. RESULTS: The mean age was 51 ± 10.4 years with a range from 31 to 78 years and a mean follow-up of 14.4 ± 7.4 months. There was a significant improvement of median GS (p < 0.0001) from preoperative (74.3%; 10.7 IQR) to postoperative values (91.7%; 6.3 IQR). A normalization of postoperative contour peak (- 0.69; 1.27 SD) and MPLD90 (4.2 mm; 0.8 SD) was noticed (p < 0.0001). Postoperative lid contour was excellent in 62 (72%), good in 16 (19%) and poor in 8 eyelids (9%). Surgical success was achieved in 42 patients (81%), from which 34 (81%) were complete. Reintervention was required in 14 eyelids (16%). CONCLUSIONS: Measuring surgical outcomes with Bézier curves allows an automated, complete and objective assessment, giving more consistency to our data compared to previous reports. Müllerotomy with graded Müller muscle disinsertion is a safe and effective procedure for Graves UER, offering predictable results.

Microvascular decompression using autologous muscle graft for trigeminal neuralgia: a case series and meta-analysis.

PURPOSE: We aimed to describe a case series of patients diagnosed with trigeminal neuralgia (TN) who were submitted to microvascular decompression (MVD) using autologous muscle graft (AMG) and perform a systematic review and meta-analysis. METHODS: Forty-four adult patients who underwent MVD using AMG between 2012 and 2022 were studied retrospectively. Demographic, clinical, and surgical factors were assessed. We systematically reviewed PubMed, Embase, and Cochrane Library from inception to May 2023. We used random-effects model for all outcomes. Heterogeneity was assessed with I2. We used R software 4.3.1 for all statistical analyses. RESULTS: Among patients in the case series, the mean age was 52 ± 12.9 years, and the proportion of females was 65.9%. Forty-one patients (93.2%) presented complete pain relief after a mean follow-up of 7.7 years. The pooled analysis of immediate pain relief was 91.3% (95% CI 82-96%; I2=78%). The good pain relief during follow-up was 88.2% (95% CI 78-94%; I2=80%) at follow-up. The recurrence rates at 6, 12, 36 months, and during follow-up were 6.2%, 10.5%, 10.3%, and 11%, respectively. CONCLUSION: In this case series and meta-analysis of over 440 patients, our findings suggest that the practice of MVD using AMG may be an efficient option in the short term as surgical treatment for TN. Further trials should compare AMG with other materials and its effectiveness in a long-term follow-up.

Closure of small skull base defects with muscle plug napkin ring technique: how I do it.

BACKGROUND: Defects through the skull base into the paranasal sinuses can occur during anterior skull base procedures, risking cerebrospinal fluid leak and infection if not repaired. METHODS: We describe a muscle plug napkin ring technique for closure of small skull base defects, wherein a free muscle graft slightly bigger than the defect is packed tightly in the defect, half extracranially and half intracranially and sealed with fibrin glue. The technique is illustrated in the case of a 58-year-old woman with a large left medial sphenoid wing/clinoidal meningioma. CONCLUSIONS: The muscle plug napkin ring technique is a simple solution to small skull base defects.

Combined laryngeal framework surgery and cricopharyngeal muscle-origin transection: a novel effective surgery for dysphagia with pharyngolaryngeal palsy and cricopharyngeal dysfunction under local anesthesia.

BACKGROUND: Cricopharyngeal myotomy and laryngeal framework surgery can improve swallowing function in patients with severe dysphagia. We developed a novel surgical technique for severe dysphagia associated with pharyngolaryngeal paralysis and cricopharyngeal dysfunction, performed under local anesthesia, and investigated its effectiveness. METHODS: We included nine patients who underwent cricopharyngeal muscle-origin transection with laryngeal framework surgery through a horizontal skin incision under local anesthesia. CONCLUSIONS: All patients demonstrated significant improvement in the Food Intake LEVEL Scale without complications. Thus, this surgical technique may serve as a useful and less invasive treatment option for patients with severe dysphagia.

Sensory Innervation of the Upper Eyelid and Its Implication for Upper Eyelid Surgery.

PURPOSE: Sensory alterations of the upper eyelid skin and eyelashes are frequently encountered after upper eyelid surgery. The objective of this study was to provide information on the exact course and distribution of sensory nerve fibers through the anatomic planes in the upper eyelid. METHODS: Ten formalin-fixed hemifaces were dissected. The nerve branches of the ophthalmic nerve in the upper eyelid were traced in an anterograde fashion. RESULTS: A total of 151 nerve fibers were recorded during dissection. The infratrochlear, supratrochlear, supraorbital, and lacrimal nerve contributed each to both the upper eyelid skin innervation and the upper eyelid rim plexus in different distribution patterns. The mean distance from the eyelid margin at which nerve fibers pierced from preseptal into the orbicularis muscle was 14 ± 1.1 mm for nerve fibers targeting the eyelid dermis and 3.7 ± 1.2 mm for nerve fibers targeting the eyelid rim plexus ( p < 0.001). The mean intraorbicular course of nerve fibers was 3 mm (0-17; standard deviation 4.1). The mean distance from the eyelid margin at which nerve fibers pierced from the orbicularis muscle into the preorbicular plane was 10 ± 1 mm for nerve fibers innervating the eyelid dermis and 1.3 ± 0.8 mm for nerve fibers innervating the eyelid rim plexus ( p < 0.001). The mean distance of the preorbicular course of nerve fibers was 2 mm (0-15; standard deviation 3.6). CONCLUSIONS: Based on the findings, a certain degree of postoperative eyelid skin numbness is inevitable while eyelash innervation may be spared in upper blepharoplasty.

Sternohyoideus-sternothyroideus muscle flap to reconstruct oronasal fistulas due to maxillary cancer in four dogs.

OBJECTIVE: To describe the repair of oronasal fistulas in dogs treated for maxillary cancer, with a novel sternohyoideus-sternothyroideus muscle flap, and to report the outcome. ANIMALS: Client-owned dogs (n = 4) with oronasal fistulas related to cancer. STUDY DESIGN: Short case series. METHODS: Maxillary defects were caused by tissue destruction by the tumor and tumor response to radiation therapy in two cases and a complication of caudal maxillectomy in two cases, one of which had neoadjuvant radiation therapy. All tumors were >4 cm at the level of the maxilla. Flaps were harvested by transecting the ipsilateral sternothyroideus and sternohyoideus muscles from their origin at the manubrium and costal cartilage. The muscles were rotated around the base of the cranial thyroid artery and tunneled subcutaneously in the neck and through an incision in the caudodorsal aspect of the oral cavity. The muscle flap was sutured to the edges of the oronasal fistula. RESULTS: The flap reached as far rostral as the level of the first premolar without tension. All dogs had clinical signs that improved postoperatively. All dogs had partial dehiscence of the flap. CONCLUSION: This flap was associated with a high rate of complications; however, all flaps were used in challenging cases. Clinical signs related to oronasal fistula were improved in all dogs in this case series.

Return to work following pelvic reconstructive surgery: secondary analysis of Operations and Pelvic Muscle Training in the Management of Apical Support Loss trial.

BACKGROUND: Patients' return to work is an important part of surgical counseling and quality of life. OBJECTIVE: This study aimed to evaluate the pattern of patients' return to work and loss of productivity after pelvic reconstructive surgery. STUDY DESIGN: This was a secondary analysis of the randomized controlled trial Operations and Pelvic Muscle Training in the Management of Apical Support Loss. The primary outcome was return to work defined by the answer to "How many calendar weeks or workdays did you not go to work after the original prolapse surgery?" Furthermore, loss of productivity included hours and days per week worked and discontinuation of paid work because of urogynecologic conditions. Moreover, predictors affecting the timing of return to work and loss of productivity were assessed. RESULTS: Here, 180 patients (49%) were working before surgery. Of these patients, half returned to work 35 days after surgery, with 21 (13%) returning to work immediately after surgery and 43 (27%) returning to work within ≤2 weeks. The number of days missed did not differ between patients who underwent sacrospinous ligament fixation and those who underwent uterosacral ligament suspension (P=.23). At 3 months, 15 patients (9%) who were working before surgery had stopped working, but those who continued to work had similar hours per week as before surgery (36±12 vs 35±13; P=.48). Of note, 17 patients (11%) reported being less productive, on average working at 60% effectiveness. Most patients (96%) reported not missing any hours of household chores by 3 months after surgery. Patients who returned to work within 6 weeks had a higher rate of retreatment with either pessary or surgery within 2 years (5 of 85 [6.8%] vs 0 of 76 [0%]; P=.03). Those who returned to work within 2 weeks worked fewer hours before surgery (30±15 vs 36±12; P=.013), were less likely to have private insurance (77% vs 91%; P=.03), and had a higher rate of retreatment (3 of 30 [13%] vs 2 of 131 [1.7%]; P=.007). There was no difference in bulge symptoms and anatomic failure based on return to work. CONCLUSION: Most patients returned to work within 35 days after surgery. Working less than full time and not having private insurance were predictors of earlier return to work.

Role of Purkinje-muscle junction in early ventricular fibrillation in a porcine model: Beyond the trigger concept.

BACKGROUND: The role of the Purkinje network in triggering ventricular fibrillation (VF) has been studied; however, its involvement after onset and in early maintenance of VF is controversial. AIM: We studied the role of the Purkinje-muscle junctions (PMJ) on epicardial-endocardial activation gradients during early VF. METHODS: In a healthy, porcine, beating-heart Langendorff model [control, n = 5; ablation, n = 5], simultaneous epicardial-endocardial dominant frequent mapping was used (224 unipolar electrograms) to calculate activation rate gradients during the onset and early phase of VF. Selective Purkinje ablation was performed using Lugol's solution, followed by VF re-induction and mapping and finally, histological evaluation. RESULTS: Epicardial activation rates were faster than endocardial rates for both onset and early VF. After PMJ ablation, activation rates decreased epicardially and endocardially for both onset and early VF [Epi: 9.7 ± 0.2 to 8.3 ± 0.2 Hz (p <.0001) and 10.9 ± 0.4 to 8.8 ± 0.3 Hz (p < .0001), respectively; Endo: 8.2 ± 0.3 Hz to 7.4 ± 0.2 Hz (p < .0001) and 7.0 ± 0.4 Hz to 6.6 ± 0.3 Hz (p = .0002), respectively]. In controls, epicardial-endocardial activation rate gradients during onset and early VF were 1.7 ± 0.3 Hz and 4.5 ± 0.4 Hz (p < .001), respectively. After endocardial ablation of PMJs, these gradients were reduced to 0.9 ± 0.3 Hz (onset VF, p < .001) and to 2.2 ± 0.3 Hz (early VF, p <.001). Endocardial-epicardial Purkinje fiber arborization and selective Purkinje fiber extinction after only endocardial ablation (not with epicardial ablation) was confirmed on histological analysis. CONCLUSIONS: Beyond the trigger paradigm, PMJs determine activation rate gradients during onset and during early maintenance of VF.

The pancreas-to-muscle signal intensity ratio on T1-weighted MRI as a predictive biomarker for postoperative pancreatic fistula after distal pancreatectomy: a single-center retrospective study.

BACKGROUND: Postoperative pancreatic fistula (POPF) is one of the serious complications of pancreatic surgery. When POPF occurs and becomes severe, it causes secondary complications and a longer treatment period. We previously reported a correlation between pancreatic fibrosis and magnetic resonance imaging (MRI) findings, and MRI may have the potential to predict POPF. This study aimed to assess the predictive ability of the pancreas-to-muscle signal intensity ratio on T1-weighted MRI (SIR on T1-w MRI) for POPF after distal pancreatectomy (DP). METHODS: This single-institution retrospective study comprised 117 patients who underwent DP. It was conducted between 2010 and 2021 at the Gifu University Hospital. We statistically analyzed pre-, intra-, and postoperative factors to assess the correlation with POPF. RESULTS: According to the definition and grading of the International Study Group of Pancreatic Fistula (ISGPF), 29 (24.8%) of the 117 patients had POPF grades B and C. In the univariate analysis, POPF was significantly associated with the pancreas-to-muscle SIR on T1-w MRI, the drainage fluid amylase concentration (D-Amy) levels on postoperative day (POD) 1 and 3, white blood cell count on POD 1 and 3, C-reactive protein level on POD 3, and heart rate on POD 3. In multivariate analysis, only the pancreas-to-muscle SIR on T1-w MRI (>1.37; odds ratio [OR] 23.25; 95% confidence interval [CI] 3.93-454.03; p < 0.01) and D-Amy level on POD 3 (>737 U/l; OR 3.91; 95% CI 1.02-16.36; p = 0.046) were identified as independent predictive factors. CONCLUSIONS: The pancreas-to-muscle SIR on T1-w MRI and postoperative D-Amy levels were able to predict the development of POPF after DP. The pancreas-to-muscle SIR on T1-w MRI may be a potential objective biomarker reflecting pancreatic status.

Fatty infiltration in cervical extensor muscle: is there a relationship with cervical sagittal alignment after anterior cervical discectomy and fusion?

PURPOSE: To investigate the relationship between the preoperative paraspinal Goutalier grade of fatty infiltration and postoperative cervical sagittal alignment in patients undergoing anterior cervical discectomy and fusion (ACDF). METHODS: A total of 101 patients who underwent single-level ACDF with the Zero-profile implant system between March 2011 and April 2020 were included in this study. Cervical sagittal alignment parameters, including the C2-C7 Cobb angle, functional spinal unit (FSU) angle, cervical sagittal vertical axis (SVA), and T1 slope (T1S), were assessed. Preoperative magnetic resonance images were used to classify patients according to Goutalier grade. Clinical outcomes including Neck Disability Index (NDI) scores, Japanese Orthepaedic Association (JOA) scores and Visual Analogue Scale (VAS) scores were collected and analyzed. RESULTS: According to the Goutalier grade, 33 patients were classified as Goutalier 0-1 (Group A), 44 were classified as Goutalier 1.5-2 (Group B), and 24 were classified as Goutalier 2.5-4.0 (Group C). The mean age among the three groups showed significant differences (P = 0.007). At the last follow-up, the C2-C7 Cobb angle, FSU angle, and T1S improved after the surgery among the groups. Although there were varying degrees of loss of curvature among the different groups during the follow-up period, the postoperative cervical sagittal alignment parameters demonstrated no statistical differences among the three groups (P > 0.05). In addition, patients in all groups experienced significant relief of their symptoms, and the clinical scores were comparable among the groups (P > 0.05). CONCLUSION: The complex nature of anterior cervical surgery requires surgical attention both in decompression and sagittal alignment. Our study demonstrates satisfactory postoperative cervical sagittal alignment of patients despite different grades of fatty infiltration of the multifidus muscle following single-level ACDF. Based on our results, the improvement and maintenance of cervical sagittal alignment after ACDF remains a complex problem that spine surgeons should consider before surgery.

Muscle loaded stability reflects ligament-based stability in TKA: a cadaveric study.

PURPOSE: This paper aims at evaluating the effects of muscle load on knee kinematics and stability after TKA and second at evaluating the effect of TKA surgery on knee kinematics and stability; and third, at correlating the stability in passive conditions and the stability in active, muscle loaded conditions. METHODS: Fourteen fresh frozen cadaveric knee specimens were tested under passive and active condition with and without external loads involving a varus/valgus and internal/external rotational torque before and after TKA surgery using two in-house developed and previously validated test setups. RESULTS: Introduction of muscle force resulted in increased valgus (0.98°) and internal rotation of the femur (4.64°). TKA surgery also affected the neutral path kinematics, resulting in more varus (1.25°) and external rotation of the femur (5.22°). All laxities were significantly reduced by the introduction of the muscle load and after implantation of the TKA. The presence of the implant significantly affects the active varus/valgus laxity. This contrasts with the rotational laxity, in which case the passive laxity is the main determinant for the active laxity. For the varus/valgus laxity, the passive laxity is also a significant predictor of the active laxity. CONCLUSION: Knee stability is clearly affected by the presence of muscle load. This points to the relevance of appropriate rehabilitation with focus on avoiding muscular atrophy. At the same time, the functional, muscle loaded stability strongly relates to the passive, ligament-based stability. It remains therefore important to assess knee stability at the time of surgery, since the passive laxity is the only predictor for functional stability in the operating theatre. LEVEL OF EVIDENCE: Case series, Level IV.

Reconstruction of the superficial femoral vessels with muscle flap coverage for soft tissue sarcomas of the proximal thigh.

BACKGROUND: Surgical resection of soft tissue sarcoma with a margin of healthy tissue may necessitate resection and reconstruction of major blood vessels together with soft tissues of the proximal thigh to preserve the limb. The long-term functional outcomes of these reconstructions remain unestablished. The aim of this report was to assess the vascular and functional outcomes of soft tissue sarcoma patients with femoral vessel reconstructions. PATIENTS AND METHODS: Patients who had undergone oncovascular reconstruction during the treatment of proximal thigh soft tissue sarcoma in 2014-2020 were reviewed for details of the vascular and soft tissue reconstructions, and the oncological and functional outcomes. This included eight patients of a median age 59 (range 19-77) years. All had a reconstruction of at least the superficial femoral artery and vein as well as soft tissue reconstruction with a muscle flap. All vessel reconstructions were done with either autologous vein (six grafts/four patients) or allograft (10 grafts/six patients). A microvascular latissimus dorsi flap, with a skin island, was incorporated to cover the vascular grafts in five patients. A pedicled sartorius or gracilis muscle flap was used to fill the defect in three patients. RESULTS: Graft patency was assessed in seven patients with a median follow-up of 48 (1-76) months. The arterial graft was patent in 6/8 and the vein graft in 2/8 patients. The gait had returned to normal in five of the six patients assessed. The median MTSS was 70 (43-87)% and the TESS 90 (75-100)%. No local recurrence of the sarcoma was detected. CONCLUSIONS: Vascular reconstruction combined with soft tissue reconstruction enables limb-sparing surgery in patients with soft tissue sarcoma involving proximal femoral vessels. Although the surgeries are complex with high early morbidity, the achieved long-term functional outcomes are worthwhile.

Muscle-Sparing Six-Point Upper Blepharoplasty for Asian Male Patients.

ABSTRACT: Dermatochalasis is a consequence of aging and results in various problems, such as tired look, dry eye syndrome, or reduced vision. Although the demand for upper blepharoplasty is growing in the senescing world, the demand from male patients has been generally overlooked. Male patients prefer natural creases and fast recoveries, with minimal swelling. The authors introduce a novel method that will satisfy the demands of most male patients. This technique includes muscle-sparing skin incisions and fixation of folds through 6 slit incisions. This study retrospectively reviewed 40 Asian male patients who had been subject to this procedure. The patients were evaluated for fold attenuation, scar perception, and patient satisfaction; favorable outcomes with minimal complications were observed.

Modified McLaughlin's Dynamic Muscle Support in the 21st Century? A Retrospective Study With a Prospective Follow-Up Analysis for Patients With Long Standing Facial Paralysis.

INTRODUCTION: Facial nerve paralysis can dramatically affect the life of a patient as it leads to significant alterations of the facial symmetry and functional limitations. Various methods exist including free neuromuscular flaps to reanimate patients suffering from uni- or even bilateral facial nerve paralysis. The more than 60-year-old technique described by McLaughlin continues to offer an alternative with distinct advantages for the individual patient. The present study aimed to evaluate clinical outcome and satisfaction of patients treated with a modified McLaughlin's Dynamic Muscle Support. MATERIALS AND METHODS: A total of 13 patients (mean age of 58.4 years) who received a modified McLaughlin's Dynamic Muscle Support due to uni- or bilateral long-standing facial paralysis were included. Medical records were reviewed retrospectively, and patients were contacted for additional follow-up. Patients who agreed to participate in the follow-up study were asked to answer a self-developed questionnaire. RESULTS: In all patients, a rehabilitation of facial symmetry with an improvement of the mimic expression could be achieved. Mean length of inpatient stay was 6.5 days and average duration of surgery was 121 minutes. No surgical site infection occurred. Mean follow-up was 23 months. Most of the patients were fully satisfied with the result and could experience functional and esthetic improvement.Patients who participated in the prospective follow-up study were very satisfied with the esthetic result and functional outcome. CONCLUSIONS: Even in times of advanced microsurgical techniques, McLaughlin's Dynamic Muscle Support appears to be a good alternative for the successful treatment of long-standing facial paralysis.

How I do it: minimizing muscle damage in microvascular decompression for hemifacial spasm.

BACKGROUND: Key hole surgery was recruited for MVD surgery since the maneuver is through the small space between the cerebellum and temporal/occipital bone. However, even small wounds can cause severe postoperative pain if there is significant tissue damage. Attention has been given to the size of the craniotomy rather than to the skin incision or soft tissues such as muscles. METHOD: Suboccipital muscle dissection focusing on splitting the splenius capitis muscle was presented. The dura was reapproximated without additional dissection to harvest a fascia graft. CONCLUSION: Muscle injury should be minimized to alleviate postoperative pain.

Targeted muscle reinnervation following external hemipelvectomy or hip disarticulation: An anatomic description of technique and clinical case correlates.

BACKGROUND: Targeted muscle reinnervation (TMR) has been shown to decrease or prevent neuropathic pain, including phantom and residual limb pain, after extremity amputation. Currently, a paucity of data and lack of anatomical description exists regarding TMR in the setting of hemipelvectomy and/or hip disarticulations. We elaborate on the technique of TMR, illustrated through cadaveric and clinical correlates. METHODS: Cadaveric dissections of multiple transpelvic exposures were performed. The major mixed motor and sensory nerve branches were identified, dissected, and tagged. Amputated peripheral nerves were transferred to identified, labeled target motor nerves via direct end-to-end nerve coaptations per traditional TMR technique. A retrospective review was completed by our multi-institutional teams to include examples of clinical correlates for TMR performed in the setting of hemipelvectomies and hip disarticulations. RESULTS: A total of 12 TMR hemipelvectomy/hip disarticulation cases were performed over a 2 to 3-year period (2018-2020). Of these 12 cases, 9 were oncologic in nature, 2 were secondary to traumatic injury, and 1 was a failed limb salvage in the setting of chronic refractory osteomyelitis of the femoral shaft. CONCLUSIONS: This manuscript outlines the technical considerations for TMR in the setting of hemipelvectomy and hip disarticulation with supporting clinical case correlates.
