Evaluation of a New Technique of Gingival Smile Reduction after Hyaluronic Acid Infiltration: A Cohort Study Focusing on Gingival Exposure and Patient-Oriented Outcomes.

A gummy smile is the visualization of more than 3 mm of gingiva above the maxillary incisors. This study aimed to evaluate the long-term effects on aesthetics and patient satisfaction of a new hyaluronic acid infiltration technique in reducing the gummy smile. Fifty patients with gummy smiles were treated using hyaluronic acid infiltration points by applying 0.1 mL per injection at specific points. Post-treatment evaluations were performed one week, one month, three months, six months, and 12 months later. A questionnaire assessed patient satisfaction, willingness to recommend the treatment, and side effects (pain and bruising during and after treatment). An average reduction of 2.5 mm in gingival exposure during smiling was observed. After one week, the reduction was constant. At six months, 40% of the original gingival exposure was recovered, and recovery was complete at 12 months. Patient satisfaction was 82.1%, and 100% of patients would recommend the treatment. Bruising, swelling, and pain decreased to 0% from the first month. In conclusion, this technique is a safe and effective option to improve the smile's appearance with minimal complications.

The Effectiveness of a Single Hyaluronic Acid Injection in Improving Symptoms and Muscular Strength in Patients with Knee Osteoarthritis: A Multicenter, Retrospective Study.

Knee osteoarthritis (KOA) is a progressive and multifactorial disease that leads to joint pain, muscle weakness, physical disability, and decreased quality of life. In KOA, the quantity of hyaluronic acid (HA) and the molecular weight (MW) are decreased, leading to joint pain due to increased wear of the knee articular cartilage. Arthrogenic muscle inhibition, which is usually found in patients with KOA, is associated with joint inflammation, pain, and swelling, also causing muscle atrophy, primarily of the anterior thigh muscles, and hindering the rehabilitation process. The aim of our work was to determine if a single HA infiltration could minimize the effects of arthrogenic muscle inhibition in patients with KOA in the short term, using isokinetic dynamometry to evaluate the strength of the knee extensor and flexor muscles of the thigh. Thirty patients with KOA who underwent both clinical and isokinetic assessment, and that received a single injection of HA, were retrospectively included. Our results showed that a single intra-articular injection of HA significantly reduces pain and improves joint function at four weeks, while non-statistically significant improvements were observed for the reference isokinetic parameter (maximum torque) at both 90°/s and 180°/s. Further high-quality studies are necessary to confirm the results of our study.

Management of Gummy Smile Using Esthetic Crown Lengthening Technique

Abstract Excessive gingival display is a major concern for a large number of patients visiting the dentist. It is a multifactorial condition that needs to be managed in a sequential manner in order to reach proper treatment technique that targets and resolves the underlying etiologies. There are different etiologies of a gummy smile, such as vertical maxillary excess, short and hyperactive upper lip, altered passive eruption, anterior dentoalveolar extrusion, or a combination of these causes. Many techniques have been used to restore the dentogingival relation for the management of gummy smile. The various treatment modalities for Excessive Gingival Display includes gingivectomy, modified lip repositioning, orthognathic surgery, orthodontic therapy, hyaluronic acid infiltration, botulin toxin injections. This case report deals with the correction of Excessive Gingival Display using conventional gingivectomy.

ULTRASOUND-GUIDED INFILTRATION WITH HYALURONIC ACID VERSUS CORTICOSTEROID FOR THE TREATMENT OF MORTON'S NEUROMA: A RANDOMIZED CONTROLLED TRIAL

BackgroundInfiltration is considered the first treatment option for symptomatic Morton's neuroma and can be performed with various medications. The aim of this study was to compare the effects of hyaluronic acid infiltration versus corticosteroid injection in the treatment of Morton's neuroma.MethodsA randomised clinical trial was conducted with 46 patients (50 feet) diagnosed with Morton's neuroma. After randomisation, the control group (CG) received three injections (one per week) of triamcinolone (Triancil®) guided by ultrasound, while the study group (SG) received three applications of hyaluronic acid (Osteonil Plus®). Patients were followed up for six months after the intervention. The primary outcome measure used was the Visual Pain Analog Scale (VAS). Secondary endpoints included patient-reported outcome measures using the American Orthopaedic Foot & Ankle Society (AOFAS) score and complications.ResultsBoth groups showed significant improvement in VAS and AOFAS scores (p < 0.001). The CG showed greater improvement than the SG in the VAS (p < 0.05) and AOFAS (p < 0.001) variables. Four patients in the CG experienced skin hypochromia at the injection site, while there were no complications in the SG.ConclusionUltrasound-guided hyaluronic acid infiltration in Morton's Neuroma proved to be safe, showing improvement in pain and function after six months of follow-up, without major complications, but with a significantly lower improvement when compared to corticosteroid injection. Taking into account cost implications and the potential for longer lasting improvement from viscosupplementation further medium- and long-term studies are needed.

"Functional Rhinofiller": Improvement of Nasal Airflow with Rhinofiller-A Retrospective Review.

Rhinofiller is an aesthetic medical technique that can significantly enhance facial aesthetics by employing hyaluronic acid infiltration. The aim of this study is to review the impact of aesthetic rhinofiller on nasal airflow. This is a retrospective review of 63 consecutive patients. The evaluation of the change in nasal respiratory flow was performed subjectively using a Likert questionnaire and objectively using a rhinomanometer, which enabled active anterior rhinomanometry (AAR). Data were collected at pre-intervention, post-intervention, and at 6-month follow-up. Among the 63 patients, the questionnaire responses resulted statistically significant both after the treatment and at the 6-month follow-up (p=0.00001). A statistically significant improvement was also observed at the rhinomanometric evaluation between pre-intervention and post-intervention (p=0.006 at 74 Pa, p=0.002 at 100 Pa, and p=0.001 at 150 Pa) and at the 6-month follow-up (p=0.008 at 74 Pa, p=0.003 at 100 Pa, and p=0.002 at 150 Pa). Differences between results were established with a Student's t-test. All p-values were two-tailed, and a value < 0.05 was considered significant. Rhinofiller can be a valuable aid in enhancing both nasal airflow and facial aesthetics. Based on our experience, it resulted in an immediate post-operative improvement in nasal airflow that remains stable in the subsequent 6 months.

Three Key Submuscular Points for Nonsurgical Rejuvenation of the Midface in Caucasian Patients: A Methodological Approach Using Injectable Hyaluronic Acid Fillers.

Since aesthetic medical treatments providing natural results are becoming increasingly popular, we developed an innovative hyaluronic acid infiltration technique for midface rejuvenation. In this prospective study, only patients with a negative or neutral lower eyelid vector were included. Treatment consisted in injecting three hyaluronic acid boluses at the cutaneous projections of the levator labii superioris, zygomatic major and minor muscles insertions. All patients were administered before treatment the FACE-Q questionnaire, whereas after treatment, they were administered the FACE-Q questionnaire and the Global Aesthetic Improvement Scale (GAIS). All treatments were documented with standardized photographs. A plastic surgeon from another Institution reviewed the photos and scored the treatments according to the GAIS scale. We included 567 patients (101 males and 466 females) who met the inclusion criteria. The mean age was 41 years, and mean follow-up time was four months. The FACE-Q scores after treatment were significantly higher (p < 0.001) in every domain investigated. The GAIS scores demonstrated significant improvement posttreatment in 89.8% of patients. An average of 1.5 ml of hyaluronic acid (VYC-20) was used for each zygomatic region. No major complications were reported; only 27 patients reported bruising, which resolved spontaneously. In all patients, there was an inversion of the lower eyelid vector, which had transitioned from neutral or negative to positive. Lifting the insertions of three selected muscles with hyaluronic acid allows a midface upward repositioning. This technique provides a reproducible and safe approach for midface rejuvenation through tissue repositioning rather than augmenting facial volume.

Comparison of the Effectiveness of Intra-articular Infiltration of Hyaluronic Acid and Corticosteroids in the Management of Knee Osteoarthritis: A Prospective Comparative Study.

Background Knee osteoarthritis (KOA) is a chronic and progressive disease of the knee joint characterized by articular cartilage destruction. It is the most common cause of knee disability and pain globally. Various treatments are used for the management of KOA; however, the role of intra-articular injections in KOA management in Pakistan remains understudied. Therefore, this study aims to evaluate the effectiveness of intra-articular injections of hyaluronic acid (HA) and corticosteroids in the management of KOA. Methodology This randomized, prospective, comparative study was conducted among 88 patients diagnosed with KOA in the outpatient department clinic of orthopedics in Benazir Bhutto Hospital, Rawalpindi, from January 2022 to January 2023. For patient enrolment, structured inclusion and exclusion criteria and a simple random sampling technique were used. Before data collection, ethical approval and informed consent were obtained. Data collection was done via a self-structured and interview-based proforma. Data analysis was performed through descriptive statistics and independent t-tests using SPSS version 25 (IBM Corp., Armonk, NY, USA). Results KOA was more prevalent in women (60, 68.18%) than men (28, 31.82%). The means for study variables such as age, Visual Analog Scale (VAS) score, and Western Ontario and McMaster Universities (WOMAC) score were 58.08 ± 7.89 years, 7.66 ± 1.8, and 71.86 ± 8.90, respectively. The incidences of right-sided and left-sided KOA were 57 (64.77%) and 31 (35.23%), respectively. Likewise, the frequency of grade II KOA was 55 (62.50%), while the frequency of grade III KOA was 33 (37.50%). Differences in the mean scores of both VAS and WOMAC between study groups were statistically significant at the second-week, sixth-week, and third-month follow-up visits. However, the mean scores of VAS and WOMAC were lower in group B than in group A at the second-week follow-up visit, whereas the scores were lower in group A compared to group B after the sixth week and third month of intra-articular injections. Conclusions Intra-articular injections of both HA and corticosteroids were adequately effective in the management of KOA-associated pain and functional restrictions; nevertheless, the benefits of corticosteroids were acute and short-term, whereas the outcomes of HA were gradual and long-term.

Comparison of the Efficacy of Two Protocol Treatments in Patients with Symptomatic Disc Displacement without Reduction: A Randomized Controlled Trial.

The aim of this study was to compare the effectiveness of arthrocentesis followed by hyaluronic acid infiltration treatment (ASH) and mandibular exercise therapy (MET) in patients with symptomatic disc displacement without reduction (DDwoR) by examining pain intensity (VAS), mandibular range of motion (MO), and quality of life (QoL). Fifty-two patients were randomly allocated into two groups, MET (N = 26) and ASH (N = 26), and therapy was applied at the baseline and one month after. Patients were followed up at 1 and 12 months after the baseline assessment. Clinical and patient-reported outcomes were compared at the baseline, 1-month follow-up, and 12-month follow-up. The study found no significant differences in VAS and MO between the ASH and MET groups at the baseline. However, while not significant, it was noted that the ASH group showed higher values for MO. Regarding OHIP-14 at 1 month of follow-up, the ASH group showed significant improvements in physical pain (p > 0.01), physical and psychological disability (p = 0.043 and p = 0.029), and handicap (p = 0.033). At the 12-month follow-up, the ASH group showed significant improvements in functional limitation, psychological discomfort, psychological disability, and handicap (p = 0.008, p = 0.001, p = 0.001, p = 0.005, respectively). ASH treatment did not reduce pain or improve mandibular range of motion more than physical therapy in patients with symptomatic DDwoR. However, ASH could be preferable given its positive long-term effects on patients' quality of life. The clinician's main objective is to prioritize the treatment plan order with a focus on the patient's quality of life. Accordingly, healthcare professionals should consider ASH as a treatment option for patients with symptomatic DDwoR who desire long-term improvement in their quality of life.

Chronic vulvar fissure: approach with cross-linked hyaluronic acid.

This report aims to prospectively describe the effectiveness and safety of injected cross-linked hyaluronic acid (HA) for the treatment of chronic vulvar fissures. A descriptive prospective case series design including 15 patients affected by chronic vulvar fissures who were treated with cross-linked HA filler between December 2020 and July 2021. The validated 21-item Vulvovaginal Symptoms Questionnaire (VSQ) was used to evaluate the results from baseline up to 9 months after the HA infiltration. A total of 15 patients suffering from chronic vulvar fissures were treated with an injection of 19 mg/mL HA filler. We found a significant improvement in VSQ scores at the end of the treatment compared to baseline. Patients reported excellent tolerance of the procedure, and no complications were recorded. Cross-linked HA infiltration of the vulvar vestibule and posterior vaginal wall appeared to be a promising approach for chronic vulvar fissures.

Infiltração intraarticular de plasma rico em plaquetas versus ácido hialurônico em pacientes com osteoartrose primária do joelho: Ensaio clínico randomizado com resultados preliminares

Objective The present study aimed to compare the effects of intraarticular infiltration of platelet-rich plasma with those of hyaluronic acid infiltration in the treatment of patients with primary knee osteoarthritis. Methods A randomized clinical trial was conducted with 29 patients who received an intraarticular infiltration with hyaluronic acid (control group) or platelet-rich plasma. Clinical outcomes were assessed using the visual analog scale for pain and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire before and after the intervention. In addition, the posttreatment adverse effects were recorded. Categorical variables were analyzed using the chi-square and Fisher exact tests, whereas continuous variables were analyzed using the Student t test, analysis of variance, and the Wilcoxon test; all calculations were performed with the Stats package of the R software. Results An independent analysis of each group revealed a statistical difference within the first months, with improvement in the pain and function scores, but worsening on the 6 th month after the procedure. There was no difference in the outcomes between the groups receiving hyaluronic acid or platelet-rich plasma. There was no serious adverse effect or allergic reaction during the entire follow-up period. Conclusion Intraarticular infiltration with hyaluronic acid or platelet-rich plasma in patients with primary knee gonarthrosis resulted in temporary improvement of functional symptoms and pain. There was no difference between interventions.

Multidisciplinary team in temporomandibular disorders

Introduction The temporomandibular disorders (TMD) are one of the main concerns regarding orofacial pathologies and there are an ascending number of cases. They are characterised as a group of pathological conditions that may affect the temporomandibular joint (TMJ), the masticatory musculature and/or other adjacent anatomical structures, leading to pain and dysfunction [1]. The multifactorial aetiology of TMD affects a relatively large number of the world population and requires a multidisciplinary evaluation and diagnosis by the clinical team [2]. Among the various elements that constitute the multidisciplinary team we highlight the dentist and the physiotherapist. The dentist as a first-line professional, most of the time is responsible for the identification of patients potentially at risk and for the follow-up of those who already present the disease [3]. On the other hand, the physiotherapist aims to reduce musculoskeletal pain, promote muscle relaxation, reduce muscle hyperactivity, improve function by restoring the quality and quantity of mandibular movements and maximise joint mobility [4]. Description of the clinical case A 24-year-old female patient with a history of temporomandibular disorder and bruxism she presented an non-assisted mouth opening (UMO) of 28 mm and an assisted mouth opening with pain in the masseter and TMJ bilaterally of 29 mm, after the clinical assessment with the DC/TMD protocol we arrived at a diagnosis of disc displacement without reduction (DDwR) with limited opening, degenerative joint disease in the left TMJ, arthralgia (II), myofascial pain (III) in the masseter with pain referred to other anatomical regions. All the assumptions of the Helsinki Declaration have been fulfilled and an informed consent for clinical case of Clinica Dentária Egas Moniz approved by the ethic commission of Instituto Universitário Egas Moniz. The treatment plan consisted of cognitive behavioural therapy (CBT), prescription of muscle relaxants, occlusal splint especially for reduction of overload due to bruxism, infiltration with 1 ml of hyaluronic acid of high molecular weight in the TMJ bilaterally followed by articular mobilisation techniques and neuromuscular and myofascial techniques. The patient was instructed to continue with the physiotherapy. Results The follow up was made 2 months after with 8 sessions of physiotherapy and 1 more hyaluronic acid infiltration bilaterally as protocoled session, we could observe an absence of temporomandibular joint pain, UMO of 42 mm, decreased crepitation, decreased intensity of myofascial pain (I) and (DDwR) without limited opening. Discussion and conclusion The multidisciplinary dentist-physiotherapist team combines inputs from different professions with the aim of promoting the best patient care and represents an added value for the management of the signs/symptoms of patients with temporomandibular dysfunction.

Injection laryngoplasty under ultrasonographic control.

Cervical ultrasound allows real-time visualization of the laryngeal structures. We describe its application for injection laryngoplasty in the voice clinic. Hyaluronic acid infiltration of the vocal fold under ultrasonographic control. With this technique, the position of the needle in the depth of the vocal fold and its spatial relations with nearby structures can be assessed. This allows for an accurate infiltration of the material in contrast to other techniques and avoids discomfort related to the gag reflex with nasofibrolaryngoscopy. No specific complications have been observed so far, however, this technique may be difficult in cases with calcified cartilages or uncooperative patients.

TL 18131 - Functional evaluation of hyaluronic acid infiltration in the subtalar joint of patients with posttraumatic osteoarthritis

Objective: To assess the efficacy of intra-articular viscosupplementation in patients with symptomatic subtalar osteoarthritis after calcaneal fracture. Methods: Thirty-eight patients with a mean age of 50 years were divided into 3 groups: hyaluronic acid (HA) alone, corticoids alone or hyaluronic acid and corticoids combined. Three consecutive doses of the appropriate medication were administered at one-week intervals. The patients were evaluated for pain and hindfoot function using the American Orthopedic Foot and Ankle Society (AOFAS) scale and the visual analog scale (VAS) at 4 different timepoints (before infiltration and 4, 12 and 24 weeks after infiltration). Results: There was significant improvement in the AOFAS score (from medians of 55 and 73 at baseline to 99 and 100 after 24 weeks; p&lt;0.001) and the VAS score (from medians of 8 and 7 before infiltration to 1 and 2 at 24 weeks after infiltration; p&lt;0.001) scores in the groups with hyaluronic acid alone and in combination with corticoid, respectively. In group 2, the scores improved after only 4 weeks (from 83 to 91.5 and from 7 to 5), returning to near-baseline values at the end of the follow-up (from 83 to 82.5 and from 7 to 7). Conclusion: Infiltration with hyaluronic acid was effective and safe and should be included in the therapeutic arsenal of conservative treatments for symptomatic posttraumatic subtalar osteoarthritis.

Prospective study to evaluate the influence of joint washing and the use of hyaluronic acid on 111 arthrocentesis.

Temporomandibular dysfunction is a generic term that covers a large number of clinical problems affecting not only temporomandibular joint but also the masticatory musculature and related structures. Arthrocentesis is used in patients with joint pathology in which conservative treatment has failed. A prospective, observational, analytical cohort study has been carried out to evaluate the results of 111 arthrocentesis. We have performed an inferential statistics study between the variables: improvement of pain and improvement in the oral opening with the variables and access joint, washing joint, hyaluronic acid infiltration, and type of joint pathology. Joint washing and intra-articular hyaluronic acid injection significantly improved the pain at 1-week, 1-month, and 3-month postarthrocentesis, although this improvement was limited in time, at 6months, joint washing and hyaluronic acid infiltration are no longer significant. Only the joint access (p = 0.014) and the type of joint pathology (p = 0.028) are significant. The effectiveness of joint access in the arthrocentesis at 6months is high, although less than at 1-month and 3-month postarthrocentesis. The type of joint pathology is another important factor. Patients with degenerative pathology worsen the most after 6-month postarthrocentesis. Arthrocentesis could avoid the evolution of acute pathology.

Effects of the hyaluronic acid infiltration in the treatment of internal temporomandibular joint disorders

ABSTRACT BACKGROUND AND OBJECTIVES: The primary protocol for the control of temporomandibular disorders prioritizes reversible and less invasive measures. However, conservative treatment is sometimes ineffective. Therefore, the use of hyaluronic acid has been suggested as a therapeutic alternative to verify the effectiveness of the hyaluronic acid in patients who are not responsive to the most conservative treatments, helping them in the control of pain. This article aims to perform a literature review on the efficacy of this substance in the treatment of internal changes of the temporomandibular joint. CONTENTS: The search strategy used the Pubmed portal and the Web of Science database for the last 10 years. We included articles in English that evaluated the efficacy of the hyaluronic acid in the intra-articular disorders of temporomandibular joint, and excluded articles from literature review, clinical case reports, theses, and dissertations. Fifteen studies, classified as randomized clinical trials, prospective and retrospective studies, case-control, pilot study, and systematic reviews were selected. The hyaluronic acid is of fundamental importance in the function and lubrication of joint tissues due to its high molecular weight. When degenerative and inflammatory changes are present, their concentration and molecular weight are diminished, and the injection of this acid raises these levels, which can generate pain relief. CONCLUSION: Intra-articular therapy with hyaluronic acid is effective in the reduction of symptomatologic levels and the functional restoration of the temporomandibular joint.

Early hyaluronidase use in preventing skin necrosis after treatment with dermal fillers: Report of two cases

Injection of dermal fillers, like hyaluronic acid (HA), is a safe procedure, with few and transient side effects such as erythema, bruising and swelling etc. The aim of this report is to provide our protocol for the early treatment of necrotic complications after facial treatment with dermal fillers. We present two cases of skin suffering of the face after dermal infiltration of HA, treated successfully with our early protocol. Our protocol includes the early infiltration of hyaluronidase in the treated areas. We start with infiltration of hyaluronidase distributed over the area to be treated through micro-injections with dosage 40 IU per cm 2.Our protocol includes the use of systemic corticosteroids for 4 days, anti-aggregation therapy, oral antibiotic, topical cream with nitric oxide and compresses with gauze and warm water. In the skin complications after dermal filler treatment, marked pain and characteristic reticulated erythema in the skin distribution of the affected vessels is often developed. Due to the implementation of our protocol in these patients, we managed to avoid an irreversible necrotic complication of the face in both cases. In this report, our protocol was compared with results published in the literature and allowed us to avoid complications such as skin necrosis with permanent damage.

Labia Majora Augmentation with Hyaluronic Acid Filler: Technique and Results

External female genitalia lose elasticity and volume with age. In the literature several techniques address the redundancy of the labia minora, but only few reports describe the augmentation of labia majora with fat grafting. At present, no studies describe the augmentation of the labia majora with hyaluronic acid. This study aims to present our technique of infiltration of hyaluronic acid filler, analyzing effectiveness, patient satisfaction, and complications. We retrospectively analyzed 54 patients affected by hypotrophy of the labia majora; they were treated with hyaluronic acid filler between November 2010 and December 2014. The Global Aesthetic Improvement Scale (GAIS) filled out by the doctor and the patients was used to evaluate the results 12 months after the infiltration. Complications were recorded. A total of 31 patients affected by mild to moderate labia majora hypotrophy were treated with 19 mg/mL HA filler; 23 patients affected by severe labia majora hypotrophy were treated with 21 mg/mL HA filler. Among the first group of patients, one underwent a second infiltration 6 months later with 19 mg/mL HA filler (maximum 1 mL). A significant improvement (P < .0001) in GAIS score was observed, both in the scores provided by the patients and by the doctor. A greater relative improvement was observed in patients affected by severe hypotrophy. No complications were recorded. Hyaluronic acid infiltration of the labia majora is able to provide a significant rejuvenation with a simple outpatient procedure. We achieved significant improvements with one infiltration in all cases. The treatment is repeatable, has virtually no complications and it is reversible. 4 Therapeutic.

Can Viscosupplementation Be Used in the Hip? An Italian Perspective

Viscosupplementation is the intra-articular administration of preparations containing hyaluronic acid or hyaluronate intended to restore the normal biological properties of hyaluronic acid normally found in synovial fluid. Infiltration of hyaluronic acid in the arthritic hip is a more recent technique than viscosupplementation of the knee due to the greater technical difficulty of infiltration to the hip, which requires fluoroscopic or ultrasound guidance. The introduction of high-molecular-weight hyaluronic acid in the treatment permits a single administration and has helped diffuse hip infiltration treatment. A single infiltration reduces patient discomfort caused by the procedure and allows treatment of a larger number of patients. Although the literature has unequivocally proven the possibility of reducing pain in patients affected by hip arthritis following infiltration, the molecular weight and density, the number of infiltrations required for long-term results, and the most appropriate indications for infiltration treatment have yet to be clarified. Selecting the patient is the first obstacle to be overcome. Therefore, infiltration should be considered as an option for patients with initial pain symptoms who have not yet been listed for joint prosthesis surgery. The radiographic criteria require at least a partly preserved joint space, and the clinical criteria of persistent hip pain and full joint mobility seem to be sufficiently effective for selection.

AB0122 Eco-guided treatment with hyaluronic acid and concomitant administration of chondroitin sulfate 800 mg/day in rizoarthrosis

BackgroundThe treatment of trapeziometacarpal joint osteoarthritis (TMO) often consists of intra-articular injections of corticosteroids and/or hyaluronic acid (HA) or oral intake of chondroprotector agents. Several studies have shown that ultrasound-guided...
