A New Multiplane Dissection Method for Frontotemporal Lift and Fixation.

Lifting procedures of the upper face have gained significant popularity, and various methods and dissection planes have been described. The deep temporalis fascia (DTF) is a crucial structure for securing lifting sutures and allowing horizontal tissue vectorization. However, achieving vertical eyebrow lifting often requires bone maneuvers and introduces potential complications. This letter proposes a novel multiplanar dissection method for the temporal and forehead regions, obviating the need for bone maneuvers in lifting suture fixations. The presence of the subgaleal fascia in the temporal region has been identified, in addition to the DTF and superficial temporal fascia. Furthermore the superficial temporal fascia is divided into 3 layers, with attention paid to their medial connection with the structures of the forehead. Surgical techniques involve meticulous dissection down to the DTF and identification of the subgaleal fascia for lateral temporal dissection or transition to the subplane of the epicranial aponeurosis for forehead lifting. By leaving a thick layer, the subplane of the epicranial aponeurosis during forehead lifting eliminates the need for drilling and reduces the risk of relapse. The described multiplanar dissection method enhances the safety and effectiveness of forehead lift procedures, offers a viable alternative to bone drilling, minimizes flap-related complications, and provides valuable insights for facial rejuvenation surgery.

Short-Term Benefits from Manual Therapy as an Adjunct Treatment for Persistent Postural-Perceptual Dizziness Symptoms: A Preliminary Prospective Case Series

Persistent dizziness and balance deficits are common, often with unknown etiology. Persistent Postural-Perceptual Dizziness (3PD) is a relatively new diagnosis with symptoms that may include dizziness, unsteadiness, or non-vertiginous dizziness and be persistent the majority of time over a minimum of 90 days. The purpose of this case series was to investigate short-term outcomes of reducing dizziness symptoms using a manual therapy intervention focused on restoring mobility in the fascia using a pragmatically applied biomechanical approach, the Fascial Manipulation® method (FM®), in patients with 3PD. The preliminary prospective case series consisted of twelve (n = 12) patients with persistent complaints of dizziness who received systematic application of manual therapy to improve fascial mobility after previously receiving vestibular rehabilitation. The manual therapy consisted of strategic assessment and palpation based on the model proposed in the FM® Stecco Method. This model utilizes tangential oscillations directed toward the deep fascia at strategic points. Six males (n = 6) and females (n = 6) were included with a mean age of 68.3 ± 19.3 years. The average number of interventions was 4.5 ± 0.5. Nonparametric paired sample t-tests were performed. Significant improvements were observed toward the resolution of symptoms and improved outcomes. The metrics included the Dizziness Handicap Inventory and static and dynamic balance measures. The Dizziness Handicap Inventory scores decreased (i.e., improved) by 43.6 points (z = −3.1 and p = 0.002). The timed up and go scores decreased (i.e., improved) by 3.2 s (z = −2.8 and p = 0.005). The tandem left increased (i.e., improved) by 8.7 s (z = 2.8 and p = 0.005) and the tandem right increased (i.e., improved) by 7.5 s (z = 2.8 and p = 0.005). Four to five manual therapy treatment sessions appear to be effective for short-term improvements in dizziness complaints and balance in those with 3PD. These results should be interpreted with caution as future research using rigorous methods and a control group must be conducted.

The effects of static and dynamic stretching on deep fascia stiffness: a randomized, controlled cross-over study.

Previous stretching studies mostly investigated effects on the skeletal muscle but comprehensive explorations regarding the role of the connective tissue are scarce. Since the deep fascia has been demonstrated to be sensitive to mechanical tension, it was hypothesized that the fascia would also respond to stretching, contributing to enhanced range of motion (ROM). Forty (40) recreationally active participants (male: n = 25, female: n = 15) were included in the randomized controlled cross-over trial and allocated to different groups performing 5min static (STAT) or dynamic (DYN) plantar flexor stretching or control condition (CC) in a random order. Pre- and immediately post-intervention, muscle and fascia stiffness, as well as muscle and fascia thickness were measured using high-resolution ultrasound and strain elastography. ROM was assessed in the ankle joint via the knee to wall test (KtW) and goniometer. STAT reduced both, muscle and fascia stiffness (d = 0.78 and 0.42, p < 0.001, respectively), while DYN did not reduce stiffness compared to the control condition (p = 0.11-0.41). While both conditions showed significant increases in the KtW (d = 0.43-0.46, p = 0.02-0.04), no significant differences to the CC were observed for the isolated ROM testing (p = 0.09 and 0.77). There was a small correlation between fascia stiffness decreases and ROM increases (r = -0.25, p = 0.006) but no association was found between muscle stiffness decreases and ROM increases (p = 0.13-0.40). Our study is the first to reveal stretch-induced changes in fascia stiffness. Changes of fascia`s but not muscle`s mechanical properties may contribute to increased ROM following stretching.

Revisiting the Use of Deep Temporalis Fascia Grafts in Ophthalmology

ABSTRACT Purpose To report new indications for deep temporalis fascia (DTF) grafts in the ophthalmic field. Methods Monocentric retrospective interventional case series study. All the patients who underwent a DTF graft in an unpublished new indication over the study period (May 2020–October 2023) were included. For each patient, gender, age, graft indication, outcomes, complications, and follow-up duration were collected. In most cases, the DTF graft was covered by a vascularized flap. Results Eight patients underwent a DTF graft over the study period. The indications were: radiotherapy-induced scleral necrosis in three cases, tendinoplasty to replace the inferior rectus muscle tendon invaded by a locally advanced conjunctival carcinoma in one case, Ahmed glaucoma valve tube exposure in one case, intraocular lens with scleral fixation exposure in one case, orbital cerebrospinal fluid fistula (orbitorrhea) in one case, and post-traumatic complete corneal graft loss in one case. The DTF graft was successful in 87.5% of cases after a mean follow-up of 11.4 months. No complications were observed. Conclusions DTF graft is a highly versatile graft that can be easily harvested. New indications for DTF grafts may include the repair of radiotherapy-induced scleral necrosis, the creation of oculomotor tendon and the temporary packing of large ocular tissue loss in an emergency context. Further studies with a longer follow-up are needed to confirm our preliminary results.

Experimental investigation of tension-reducing effectiveness of keystone perforator island flap

Background and aim. Nowadays, the reconstruction of large and complex defects with keystone perforator island flaps (KPIF) has gained popularity in plastic and reconstructive surgery. The keystone perforator island flap was described as a curvilinear shaped trapezoidal design flap, with two V-Y advancement flaps end-to-side. It is a multiperforator advancement flap, based on multiple fasciocutaneous or musculocutaneous perforators, described by Behan in 2003. These flaps have a simple harvest technique, an easy-to-implement design, and they are time and cost-saving. Their blood supply lends a versatile and robust character, with less complications. Nonetheless, their biomechanical properties and effectiveness are unclear, the wound-closure tension-reducing effect is not well documented in existing literature. The present study aims to investigate the wound closure tension-reducing effect of type I, type IIA, type Sidney Melanoma Unit I (SMU) and type SMU II KPIFs. The main purpose of this study was to clarify the tension-reducing effect of the KPIF technique, which can contribute to the understanding of the biomechanical benefits of the KPIF. Methods. This is an experimental, in vivo study, based on twelve white race porcine models (PIC-FII-377), as their anatomy and wound healing process is very similar to that of humans. In this study, 42 wounds that could not be closed by primary wound closure, known as ‘unclosable’ elliptical defects, were created in six different anatomical regions. The criteria used for not achieving primary wound closure were the breaking of 0 nylon suture or the edges of the wound. Each defect was closed with different types of keystone perforator island flap: type I, type IIA, type Sydney Melanoma Unit I and type Sydney Melanoma Unit II. Keystone perforator island flaps were used in 42 cases. Intraoperative tissue tension was measured by an AXIS FB50, 50 N force gauge tensiometer. In all cases a wide elliptical excision was performed for the primary defect. Before reconstruction, tissue tension was measured across the widest point of the elliptical primary defect. Skin incision was performed for the first flap, without division of deep fascia. After preparing first flap, tension was measured at the widest point of the wound. Furthermore, deep fascia for the second flap was divided, tissue tension across the widest point of the primary defect was measured. Finally, tension was measurement across the widest point of the donor-site after closure of the defect-side flap and V–Y closure of either end of keystone perforator island flap. Results. In this study were included 12 porcine model (PIC-FII-377). A number of 42 keystone perforator island flaps were performed in this study, in six different anatomical regions, ranging between 3.3 x 12 cm and 16 x 30 cm. All elliptical defects were unclosable, with varying sizes ranging between 2 x 4 cm and 8 x 20 cm. The mean tension that was required to close all wounds with primary closure initially was 24.51 N ± 10.73 N. After using a type I KPIF a tension decrease of -7.04 N ± 4.93 N was seen, in the case of type IIA KPIF the tension decreased to -12.43 N± 5.63 N. Furthermore, after reconstruction with type SMU I KPIF the tension decreased to -7.38N ± 5.21N. After using a type SMU II KPIF a tension decrease of -10.52 N± 5.74 N was seen. Conclusions. The main purpose of this study was to clarify the tension-reducing effect of the KPIF technique, which can contribute to the understanding of the biomechanical benefits of the KPIF. The outcomes of the present study suggest that type I, type IIA, type SMU I, and SMU II of keystone perforator island flaps have a significant tension-reducing effects, especially the technique that involves the division of the deep fascia. The results of this experimental research thoroughly explain the benefits of these flaps. The effectiveness of the flap and doubts on biomechanical properties have not been answered so far. It will encourage more plastic surgeons to use the flap, especially given its proven benefits.  

Ultrasound evaluation of deep fascia thickness: Reliability and association with clinically evaluated changes

BackgroundThere is growing evidence of fascial involvement in musculoskeletal pathologies; thus, measuring the fascia's properties is clinically essential. Objectives1) to evaluate intra- and inter-tester reliability of sonographic measurements of deep fascia thickness in healthy individuals; 2) to assess whether fascial thickness in areas of fascial movement restriction (fascial densification in Stecco's Fascial Manipulation method), differs from contralateral areas with normal fascia. MethodsPart 1 (reliability study): Fascial thickness was sonographically measured in 10 sites (5 on each side), twice by a single examiner to assess intra-rater reliability and once by a second examiner to evaluate inter-rater reliability.Part 2 (cross-sectional study): Unilateral fascial movement restrictions were detected in 5 bilateral sites by palpation. The fascial thickness on the ultrasound image was measured at the restriction site and its normal contralateral side by a blinded assessor. Results21 healthy individuals were evaluated in part 1, 15 healthy individuals in part 2. Intra-tester reliability (Interclass correlation – ICC) values ranged from 0.677 to 0.975; inter-tester ICC values ranged from 0.473 to 0.966. No significant differences in fascia thickness between the right and left body sides were observed in most sites. Significant differences were found between the fascial thickness of the site of fascial movement restrictions vs. normal counterpart. ConclusionsIntra- and inter-rater reliability of sonographic measuring fascial thickness was high, and fascial thickness of the site of fascial movement restrictions was greater than in the normal counterpart. Ultrasonography may be used as a reliable method to evaluate fascial alterations.

The Crossing Motor Ulnar Nerve Branch at Elbow

BACKGROUND AND OBJECTIVES: Cubital tunnel syndrome is the second most common nerve entrapment, and understanding the anatomy is crucial for the success of the nerve release. During ulnar nerve release for cubital tunnel syndrome, a motor branch is frequently encountered crossing anteriorly over the ulnar nerve from its medial/ulnar side proximally to the lateral/radial side distally. Little has been noted about this crossing branch in the literature. In this anatomic study, we sought to characterize this branch further and discuss its potential significance in cubital tunnel release. METHODS: We performed a cadaveric dissection of 48 elbow specimens as if performing a cubital tunnel release. We assessed for the presence of the crossing motor branch of the ulnar nerve and measured the distance from the medial epicondyle to the branch takeoff and to its target of innervation. RESULTS: Of our 48 specimens, 34 (71%) were noted to have a crossing motor branch at the area of compression by the deep flexor carpi ulnaris muscle fascia (common aponeurosis). On average, the distance from the medial epicondyle to the branch origin from the ulnar nerve was 18.2 mm and to the target muscle innervation was 28.4 mm. CONCLUSION: Identifying this branch is important for performing a cubital tunnel release, and awareness of this anatomy during ulnar nerve decompression procedures may help avoid injury to this motor branch.

“Pure Fat Flap”—Perforator-based Adiposal Layer Only Flap for Lateral Ankle Reconstruction

AbstractLateral ankle soft tissue defects pose challenges, especially in cases due to chronic pressure from cross-legged sitting, which usually present with a large dead space, small skin opening that often accompanies an open joint. Traditional reconstruction methods using fasciocutaneous flaps may result in donor site morbidity such as delayed wound healing or nerve injury. In this article, we present a case of diabetes-related lateral ankle defect successfully treated using adiposal layer only flap, also known as pure fat flap. The anatomy and the surgical technique of adiposal layer only flap were reviewed. These flaps preserve the subdermal plexus and deep fascia while obliterating dead space and providing a gliding surface for proper ankle movement. A perforator-based adiposal layer only flap was elevated from the peroneal artery and used to cover the defect. Flap perfusion was confirmed using indocyanine green video angiography and color duplex ultrasound. Patient had a successful recovery with minimal donor site morbidity. The technique expands the reconstructive microsurgeon's options for complex ankle coverage, ensuring optimal wound healing and functional outcomes.

Morphofunctional characteristics of muscle fascia and the impact of its mobilization on the sports scene: an integrative review

The use of myofascial release has been the subject of study by scholars from different areas of health. Although there is a smaller number of researches, scientific findings point to a strong impact of its inclusion in protocols. Objective: to identify the morphofunctional characteristics of the muscular fascia and the impact of its mobilization in the sporting scenario. Method: the search was carried out in the LILACS, MEDLINE, SciELO, SPORTDiscus and Embase databases, using the SPIDER strategy. Results: 40 stud-ies were selected, which revealed the main aspects regarding energy transmissibility through the muscular fascia. Conclusion: it is important to strengthen the relationship between the inclusion of myofascial release in protocols and the professional's skills. This research suggests combining self-applied release with Foam rollin with other standard stretches over a period of at least 8 weeks for ROM and explosive strength, before or after warm-up, with the purpose of both performance and prevention for athletes.

Free temporalis muscle fascia graft in dural reconstruction following surgical resection of intermediate and malignant skull base tumors: A 10-year experience from a single center.

Data from patients with post-ablative dural defects reconstructed using a free temporalis muscle fascia graft (FTFG) after resection of anterior or central skull base tumors were retrospectively analyzed. The primary predictor and outcome variables were the reconstructive methods for dural repair and postoperative cerebrospinal fluid (CSF) leakage rate, respectively. Eighty patients were included, and 94 postoperative dural reconstructions were performed using FTFG. The postoperative CSF leakage rate was 3.19%. The postoperative CSF leakage rates did not significantly differ between open and endonasal endoscopic surgeries (1.92% vs. 4.88%; p > 0.05). In cases completed using the endonasal endoscopic approach, the postoperative CSF leakage rate was significantly associated with the intraoperative CSF leak flow (p < 0.05). Post-ablative dural defect reconstruction using FTFG resulted in low postoperative CSF leakage and complication rates comparable to those of free fascia lata graft from available literature.

The influence of fascial manipulation on shoulder range of motion, pain, and function in individuals with chronic shoulder pain

BackgroundA prevalent musculoskeletal condition that has a substantial socioeconomic impact and causes considerable morbidity is chronic shoulder pain (CSP). CSP may result from a dysfunction of the upper quarter region's (UQR) myofascial continuum (MC), which is connected by deep fascia. Fascial Manipulation® (FM), proposed by Luigi Stecco, involves deep kneading performed at specific points on the deep fascia. FM is considered to reinstate the gliding of the fascial layers, thus may aid in the reduction of pain and improvement of shoulder function. ObjectiveThis study aims to determine the influence of FM on shoulder pain, passive range of motion (PROM), and function in participants with CSP. DesignSingle group, pretest-posttest design. MethodEighteen individuals with CSP aged 18–45 years were recruited. FM was applied to the painful and densified centre of coordination (CC) points on the MC of the UQR based on Stecco's FM method. The therapist performed the baseline, post-treatment, and numerical pain rating scale (NPRS) at rest and during activity, PROM, and pressure pain threshold (PPT). The follow-up measurements were done after seven days following the FM intervention. Also, the baseline and follow-up measurements of disability of arm, shoulder, and hand (DASH) score were performed. ResultsA considerable improvement in all shoulder PROM (p < 0.01), DASH score (p = 0.01), and pain reduction (p = 0.01) following FM were observed. However, the PPT showed no differences following FM (p > 0.05). ConclusionFM may be an effective treatment strategy in reducing pain and improving shoulder range of motion and function in patients with CSP.

[Application of acellular dermal matrix in prevention of laryngeal stenosis in glottic carcinoma].

Objective:To investigate the effect of acellular dermal matrix in preventing laryngeal stenosis in glottic carcinoma patients. Methods:Fifty-five patients with glottic carcinoma（T2, T3） from February 2018 to December 2022 were divided into experimental group（28 cases） and control group（27 cases） according to their wishes. Acellular dermal matrix was placed in the operation cavity in the experimental group after laryngofission, while control group 12 cases were sutured by pulling the upper and lower edges, 15 cases were repaired with sternohyoid muscle fascia flap. Results:In the experimental group, 1 case had laryngeal stenosis caused by laryngeal mucosa swelling after operation, and extubated successfully after symptomatic treatment. In the control group, 7 cases had laryngeal stenosis after operation, of which 3 cases were caused by granulation tissue hyperplasia in laryngeal cavity, and extubated after symptomatic treatment. 2 cases extubated after operation suffered from progressive dyspnea during radiotherapy, and underwent tracheotomy again, extubation successful after treatment. 2 cases caused by laryngeal mucosa swelling, after symptomatic treatment, one case was successfully extubated, and one case had long-term intubation. The laryngeal stenosis rate of the experimental group was 3.6%（1/28） , which was lower than control group 25.9%（7/27）, and the therapeutic effect of the experimental group was significantly better than control group （χ²=5.526, P=0.019）. Conclusion:Implanting acellular dermal matrix in the operation cavity of glottic carcinoma can reduce the occurrence of laryngeal stenosis and have satisfactory preventive effect on laryngeal stenosis.

Сapabilities of Dynamic Infrared Thermography for Planning and Monitoring of Perforating Flaps

Background. Free perforating flaps are the most optimal for reconstruction of both upper and lower extremities. However, along with the obvious advantages of these flaps, there are also a number of difficulties associated with their more complex vascular anatomy and, as a consequence, more time-consuming dissection. This determines the need for a more thorough preoperative planning, including the mapping of perforating vessels and development of flap design. At the same time, the problems with intraoperative assessment of perfusion of perforating flaps and their monitoring in the postoperative period have not been solved. For these purposes, several instrumental methods of examination such as MRI and CT angiography, Doppler sonography, ICG and dynamic infrared thermography are used.&#x0D; Aim of the study — to evaluate the capabilities of dynamic infrared thermography (DIT) for mapping of perforating vessels when planning the design of perforating flaps, as well as for assessing their intra- and postoperative perfusion.&#x0D; Methods. We have analyzed the results of using DIT along with CT-angiography and Doppler sonography for preliminary mapping of perforating vessels in the design of 18 perforating flaps (ALT flap — 10, SCIP flap — 8) transplanted in 15 patients from 01.01.2022 to 30.07.2022. DIT was also used in all cases for intraoperative instrumental confirmation of flap perfusion and for its monitoring in the postoperative period.&#x0D; Results. A total of 39 perforating vessels were detected by CT angiography at the point of origin from the main arteries. DIT was used to detect the distal portions of 37 perforating vessels in 15 patients at the marking of 18 flaps. On average, 2.5 per ALT flap and 1.4 per SCIP flap. Thermographic examination time was approximately 10 minutes. Localization of all perforating vessels detected by DIT were first confirmed by Doppler sonography and then visualized intraoperatively during flap dissection. Intraoperatively, perfusion of all transplanted flaps was clearly confirmed by DIT. In the postoperative period, perfusion problems were clinically detected in 3 (16%) flaps and confirmed by DIT: venous stasis — 2 cases, arterial insufficiency — 1 case. In two patients (13%) with a body mass index of more than 35 (corresponding to class 2–3 obesity), the location of perforating vessels could not be determined by thermography and Doppler sonography. Also, in these patients DIT was ineffective for confirmation of flap perfusion intraoperatively and in the postoperative period.&#x0D; Conclusion. This study confirms that CT angiography, Doppler sonography and infrared thermography are complementary methods that allow to detect and visualize perforating arteries from their origin from a main artery to the site of their passage through the deep fascia (CT-angiography), as well as to determine their more accurate projection on the skin surface (DIT and Doppler sonography). DIT is also an auxiliary method for flap monitoring in the intraoperative and postoperative periods, which allows to engage nursing staff in postoperative monitoring.

Triplane technique for breast reconstruction after breast cancer surgery: A case series report.

Implant-based breast reconstruction is an important method for post-mastectomy breast reconstruction. Currently, the most commonly used technique is the biplane technique. However, the high rate of postoperative complications, the inability of pockets to accommodate larger implants, and the expensive costs of biological mesh make the development of new surgical methods urgent. The triplane technique for breast reconstruction is an ideal candidate method. The main local symptoms were breast lump, abnormal breast skin, nipple discharge, and abnormal nipple or areola in 24 patients. The study included 24 female patients who underwent breast reconstruction using the triplane technique after radical breast cancer surgery. The surgical procedure involved measuring the dimensions of the breast, designing the incision, and creating a pocket for the implant using the triplane technique, which includes the pectoralis major muscle, the pectoralis major fascia continuing to the rectus abdominis fascia, and the latissimus dorsa muscle fascia continuing to the rectus abdominis fascia. Postoperative follow-up included regular assessments of pain and evaluation of breast appearance. No cases of postoperative infection were observed in all patients. During the 1-year follow-up period after surgery, 5 patients (20.8%) who needed radiotherapy after mastectomy for cancer showed slight darkening of skin flap pigment after using the triplane technique implant. No cases of exposure or infection of the expanders were reported, and 1 patient underwent expander replacement with a permanent prosthesis. All patients expressed satisfaction with the reconstructed breast shape. The 10 patients (41.7%) experiencing postoperative swelling and pain. However, the pain gradually subsided during the postoperative recovery period. No cases of local recurrence or distant metastasis of breast cancer were observed during the 1-year-follow-up period. The triplane technique for breast reconstruction after breast cancer surgery provides good implant coverage, reduces the risk of complications, and is cost-effective.

Intelligent method to predict intensive care unit admission after drainage operation in patients with deep neck space abscess: A multicenter retrospective study.

A deep neck space abscess (DNSA) is a critical condition resulting from infection of deep neck fascia and soft issue, leading to high morbidity and mortality. Therefore, intensive care can be very significant for patients with DNSA. This study aimed to develop models to predict the need for postoperative intensive care in patients with DNSA. We retrospectively analyzed the records of 332 patients with DNSA who received drainage operation between 2015 and 2020. Multivariate logistic regression analysis and the eXtrem Gradient Boosting (XGBoost) algorithm were used to develop predictive models. We developed two predictive models, the nomogram and the XGBoost model. The area under the curve (AUC) of the nomogram was 0.911 and of the XGBoost model was 0.935. We developed two predictive models for guiding clinical decision making for postoperative ICU admission for DNSA patients, which may help improve prognosis and optimize intensive care resource allocation.

Anatomy of the temporal region to guide filler injections.

Hollow temples are not typically considered aesthetically pleasing, and hollowness worsens with the aging process. When filling this region with fillers, there are several anatomical considerations, with injection techniques varying depending on the layer targeted. Specifically, injections between the superficial temporal fascia and the superficial layer of the deep temporal fascia are performed using a cannula, while periosteal layer injections involve the use of a needle to reach the bone before inserting fillers. Detailed anatomical insights encompass the boundaries of the temporal fossa and cautionary notes regarding blood vessels, supported by specific studies on veins and arteries in the temporal region. Complications, including vessel injuries, are discussed alongside an exploration of various injection techniques. This review provides a comprehensive exploration of anatomical considerations and the specific methodologies employed in temple augmentation with fillers.

Exploring fascial properties in patients with depression and chronic neck pain: An observational study

BackgroundDepressive disorder and chronic pain are prevalent conditions that often co-occur. The myofascial fascial continuum has been hypothesized to contribute to both conditions. However, limited research exists on the specific association between fascial properties and chronic pain and depression. ObjectiveThis study aims to investigate the properties of the deep fascia of the M. trapezius and their relationship with depression, chronic neck pain, and cervical spine mobility. MethodThis study compared fascial properties between two groups: individuals with depression and chronic neck pain, and healthy individuals. Fascial thickness, elasticity, and stiffness were measured as primary outcomes using standardized techniques such as ultrasound imaging and compliance meter. Statistical analyses were conducted to identify potential differences and correlations in fascial properties between the two groups. ResultSignificant differences emerge in stiffness, tone, and fascia thickness in the deep fascia, alongside identified correlations between depression, chronic pain, and these variables. ConclusionThe study highlights the impact of depression and chronic pain on fascial properties, emphasizing the need for further research in this domain to unravel the intricate connections and potential implications for treatment strategies.

Analgesia-nociception index accurately predicts inadequate pectoralis muscle fascia block (PECS) in patients undergoing breast surgery: A prospective observational study

BackgroundPostoperative opioid administration has been largely replaced by regional anesthesia techniques. We aimed to determine whether intraoperative Analgesia-Nociception Index (ANI) can aid in early evaluation of the effectiveness of regional blocks such as the pectoralis muscle fascia block (PECS, pectoserratus and interpectoral plane blocks) and predicting the need for analgesics postoperatively. MethodsThis prospective observational study enrolled 30 women (age: 20–80 years) undergoing unilateral, non-intubated, breast tumor excision alone or in conjunction with sentinel lymph node biopsy. PECS block was performed following sedation. ANI readings were obtained at 1-min intervals, and polar coordinates were assigned to the distance from the nipple (0.5-cm intervals) and o'clock position (15-min intervals) for each reading. Pain scores were assessed using a numeric rating scale from 0 to 10, and analgesics were administered depending on pain score post-operatively. Results8 (27%), 19 (63%), and 3 (10%) patients received morphine, tramadol, and no analgesics, respectively. In total, 954 ANI measurements were obtained. At the proposed cut-off of 50, the sensitivity and specificity of the ANI nadir for need of post-operative opioids were 0.875 and 0.932, respectively. Block effectiveness was most satisfactory in the upper lateral quadrant of the breast with nipple–areolar complex (NAC) sparing effect. Most average ANI measurements for the NAC were <50. No patient experienced postoperative nausea/vomiting, although one reported dizziness. ConclusionsThe intraoperative ANI nadir <50 was strongly correlated with need for postoperative opioids. The ANI may aid in objectively evaluating the effectiveness of pectoralis muscle fascial blocks and predicting postoperative need for analgesics.
