Comparison of the Efficacy of Two Different Local Anesthesia Techniques for Mesotherapy in Temporal Region Alopecia.

Introduction Mesotherapy is a wide range of minimally invasive injections. In mesotherapy, a mixture of various tonics is injected into the skin. These include plant extracts, various medications, vitamins, enzymes, hormones, growth factors, and other factors that will help treat alopecia. Most commonly, a mixture of platelet-rich plasma (PRP) and vitamins is used. In mesotherapy treatment for hair regrowth in the temporal region, zygomaticotemporal nerve blocks, supratrochlear nerve blocks, and supraorbital nerve blocks are given. The zygomaticotemporal nerve, supraorbital nerve, and supratrochlear nerve are the branches of the trigeminal nerve. They provide sensation on the lateral side of the forehead, which is the temple region.  Methods A sample size of 100 people was taken for the study who were undergoing mesotherapy in the bilateral temporal region for alopecia. Each group had 50 subjects: group I was given supratrochlear, supraorbital, and zygomaticotemporal nerve blocks as local anesthesia techniques, and group II was given supratrochlear and supraorbital nerve blocks. PRP was injected using an insulin syringe. Pain was assessed using a visual analog scale (VAS). Results During the procedure, a mean VAS of 1 and 3 was observed in groups I and II, respectively, during the procedure (p-value 0.023). A mean VAS of 3 and 5 was observed in groups I and II, respectively, after three hours (p-value 0.000). This shows a significant difference in the pain experienced by the subjects between the groups.  Conclusion This study proves that the zygomaticotemporal nerve, used along with supratrochlear and supraorbital nerve blocks, is better at producing analgesia and reducing pain.

CHARACTERISATION OF RESORBABLE AND NON- RESORBABLE SUTURES COATED WITH Punica granatum SEED EXTRACT: AN in vitro PILOT STUDY.

BACKGROUND: In order to achieve uneventful and rapid healing of the tissues, a suture material should be biocompatible, easy to handle, sterile, and have good and uniform tensile strength. Hence, in the present study, characterization of the suture materials was done through a novel green chemistry approach using Punica granatum seed extract. MATERIALS AND METHODS: Ethanolic extract of P. granatum seed was prepared by dissolving 25 g of P. granatum seed powder with 100 mL of ethanol. The obtained extract was coated in silk and Vicryl suture material and was tested for its surface morphology (SEM), tensile strength, anti-microbial activity, biocompatibility, and wound healing potential. RESULTS: Silk and Vicryl sutures coated with P. granatum seed extract showed the uniform coating and deposition of extract with sustaining integrity. Vicryl suture coated with the extract had good tensile strength and antimicrobial activity. The in vitro scratch assay and biocompatibility test showed that the P. granatum seed extract had excellent wound healing potential and can be used without any effect on the viability of the normal cells. CONCLUSION: Within the limitations of the study it can be concluded that P. granatum seed extract coated Vicryl sutures had good tensile strength and anti-microbial activity. P. granatum seed extract also showed excellent biocompatibility and wound healing potential.

Comparison of Efficacy of Platelet-Rich Plasma With and Without Topical Minoxidil for Hair Growth in Patients With Androgenetic Alopecia: A Prospective Study.

Introduction Androgenetic pattern of alopecia is a common problem occurring in men, which mostly arises from their younger age. There are many therapies advocated in the literature for hair loss reduction, and one of them is platelet-rich plasma (PRP) therapy. This study aimed to assess the efficacy of combined PRP therapy with topical minoxidil over PRP as monotherapy in hair loss reduction and regeneration of new hair. Materials and methods The study was conducted at our institute in the Department of Oral and Maxillofacial Surgery at Saveetha Dental College and Hospital. The study consisted of 40 participants, 20 of whom had only PRP therapy as part of their treatment, while the other 20 participants received PRP combined with topical minoxidil as treatment. Both group participants were evaluated for postoperative hair shaft diameter and hair follicle density. Parameters were measured preoperatively and postoperatively after one month, two months, and three months. Data analysis was done with the help of SPSS, with P-values less than 0.05 considered statistically significant. The Mann-Whitney U test was used to compare the two groups for measurement of hair shaft diameter, and for comparison between hair follicle density, an unpaired t-test was used. Results It was found that the mean hair shaft diameter in the PRP with minoxidil group was higher than that of the PRP group for one month (P = 0.023), two months (P = 0.001), and three months (P = 0.001) postoperative periods, and the results were statistically significant. Hair follicle density (mean hair quantity) was higher in the PRP group than in the PRP with the minoxidil group in the first postoperative month. However, this difference was not statistically significant (P = 0.08). While the mean hair quantity in the PRP with minoxidil group was higher than that in the PRP group for two months (P = 0.45) and three months (P = 0.001) postoperative periods, the results were statistically significant only at the three-month postoperative period. Conclusion It can be concluded that injectable autologous PRP with minoxidil as a topical agent is a better treatment option for the improvement of both hair quality (hair shaft diameter) and hair quantity (hair follicle density) compared to plain autologous injectable PRP monotherapy.

Comparison of the Efficacy Between Regional Nerve Block and Ring Block as Local Anesthetic Techniques for Platelet-Rich Plasma Treatment.

Introduction Platelet-rich plasma (PRP), a solution of concentrated platelets, has been widely used to promote wound repair and tissue regeneration. In the treatment of pattern hair loss, platelets in PRP secrete an abundance of growth factors, including platelet-derived growth factor (PDGF), fibroblast growth factor(FGF), and many more, which stimulate and increase signaling molecules and accelerate cell proliferation. In the PRP treatment for hair regrowth, the supratrochlear nerve (STN) block and supraorbital nerve (SON) block are given to anesthetize the scalp up to the vertex except for the temporal region. The ring block is the common local anesthetic technique used by infiltrating local anesthetic agents around the target area. The primary objectives were to compare the pain and anesthetic success rates produced by regional nerve blocks and ring blocks. Materials and methods A sample size of 100 patients undergoing PRP treatment for hair regrowth were taken as the subjects for the study. Patients were allotted into two groups by randomization. Group 1 was given regional nerve blocks as the anesthetic technique used for local anesthesia, and group 2 was given ring blocks. In the study group, STN and SON blocks as the regional nerve blocks were given 2% lignocaine with 1:80000 adrenaline to anesthetize the area, and the PRP was injected from the anterior hairline up to the vertex of the scalp, not involving the occipital and temporal regions. In the control group, a ring block was given for the same procedure. Participants from both groups were assessed for the pain and analgesia caused by ring block and regional nerve blocks using the visual analog scale (VAS). Results A mean rank of 30.28 was observed for the regional nerve block technique, and a mean rank of 70.72 was observed for the ring block technique. A p-value of 0.00 that is <0.05 was observed, which shows there is a significant difference in the pain and the analgesia experienced by the subjects between the two groups, during and three hours after the procedure. Conclusion PRP is one of the most commonly used treatments for hair regrowth. The ring block is the common local anesthetic technique used for producing anesthesia, while regional nerve blocks are more effective in producing local anesthesia. This study proves that STN and SON blocks are better anesthetic techniques than the ring block technique for PRP treatment in hair growth.

Efficacy of Tranexamic Acid in Preventing Alveolar Osteitis in Post-extraction Sockets of First Premolars.

OBJECTIVES: The present study is a randomized trial for comparing the effectiveness of tranexamic acid as an antifibrinolytic agent in preventing alveolar osteitis in the post-extraction period in patients receiving orthodontic therapy that requires extraction. METHODOLOGY: This research was carried out in the Department of Oral and Maxillofacial Surgery, Saveetha Dental College and Hospitals, Chennai, India. A total of 40 patients were considered subjects for the research. Patients undergoing orthodontic treatment referred to the Department of Oral and Maxillofacial Surgery for the therapeutic extractions of the first premolars were considered for this study. Randomization was done to split the population into study and control. After the atraumatic extraction of the first premolars under local anesthesia using 2% lignocaine with 1:80000 adrenaline, a tranexamic acid solution of 500 mg soaked gauze over the extraction sockets was used as the intervention in the study group, and plain gauze was used on the control group. Patients were asked to hold the gauze in place for one hour. Participants were reviewed after three days for the incidence of alveolar osteitis and pain severity and healing of the extraction sockets.  Results: The prevalence of Alveolitis sicca dolorosa was found to be 5% in the research group and 15% in the control group. Patients in the control group showed more pain than the patients in the research group. The period taken for healing ranged from 7 days to 10 days in the control group and 10 days to 12 days in the study group.  Conclusion: This study gives an edge that tranexamic acid can be used as a local hemostatic agent in preventing fibrinolysis of clots and preventing alveolar osteitis.

An Extremely Rare Case of Synchronous Low-Grade Polymorphous Adenocarcinoma With Canalicular Adenoma of the Minor Salivary Gland of the Palate.

Tumors of the salivary gland are a group of complex, heterogeneous lesions that are located either in the parotid gland, submandibular gland, sublingual gland, or minor salivary glands. These tumors have a wide range of etiology, pathophysiology, treatment, and prognosis. Multiple salivary gland tumors are extremely rare and usually occur more commonly in major salivary glands than in minor glands. A 61-year-old man with a chief complaint of swelling in the upper jaw for the past eight years reported to the department of oral and maxillofacial surgery. Incisional biopsy revealed a canalicular adenoma (CA) of the minor salivary gland of the palate. Wide local excision was done with closure using a buccal pad of fat and a collagen sheet. Surprisingly, the excisional biopsy was suggestive of synchronous low-grade polymorphous adenocarcinoma (PAC) with CA of the minor salivary gland of the palate. This appears to be the first reported case of PAC with CA found in the palate.

Botulinum Toxin Injection for Masseteric Hypertrophy Using 6 Point Injection Technique - A Case Report. Proposal of a Clinical Technique to Quantify Prognosis.

Introduction: Masseter hypertrophy presents as unilateral or bilateral swellings over the ramus and angle of the mandible. It is caused by malocclusion, clenching, TMJ disorders, etc and alters facial symmetry, leading to discomfort and negative cosmetic impact in many patients, making this a popular request for aesthetic and functional correction. Materials and Methods: This case report involves injecting Botulinum toxin into 6 equidistant bulging points on the masseter. Standardized photography and clinical parameters were used to assess facial contour and masseter muscle thickness at baseline and successive follow ups. Results and Discussion: Significant masseteric bulk reduction was observed in subsequent follow ups. Conclusion: The 6-point technique was found to be an effective treatment modality for Botox injection in masseteric hypertrophy. The clinical method to quantify prognosis was easy and economical.

Conventional fibrotomy and reconstruction with lateral thigh dermal fat pad in grade III oral submucous fibrosis patients: A case report and review of literature.

Oral submucous fibrosis is a chronic debilitating premalignant condition with progressive stiffening of oral mucosa ultimately ending in trismus most commonly from substance abuse. The most common etiological factor is the consumption of areca nut. Patients usually report to us when the mouth opening is almost nil. Various grafts have been used in the reconstruction of buccal defects after fiberotomy, the most popular being the buccal fat pad. We present the case of a 34-year-old man presenting with the complaint of reduced mouth opening and burning sensation in the mouth for 8 months. The patient is a poor candidate for buccal fat grafting as the patient body type being ectomorphic. The patient had a stigma of scar in the abdomen; hence, the possibility of an abdominal fat graft was out of the equation. Therefore, dermal fat is was harvested from the lateral thigh and reconstructed into the defect. The patient had a favorable outcome with good healing. Further studies are required to assess the quality, microscopic features of the adipose tissue, and the fate of dermal fat from the anterolateral thigh region.

mRNA Expression of Ezrin in Gingival Crevicular Fluid and Whole Blood of Gingivitis and Chronic Periodontitis Patients - A Polymerase Chain Reaction Study.

Background: A comparative analysis of protein expression of gingival crevicular fluid (GCF) obtained from healthy individuals and individuals with periodontal diseases would help to identify proteins involved in periodontal disease progression. Among the identified proteins, Moesin which is a disease-associated protein belongs to the ezrin-radixin-moesin protein family and was proved to play an important role in the recognition of oral bacteria contributing to the consequent development of inflammatory immune responses involved in periodontal disease development. Aim: The aim of the study is to quantify and compare mRNA expression levels of ezrin in GCF and whole blood of gingivitis and chronic periodontitis patients. Materials and Methods: A total of 60 patients were selected for the study and were divided into three groups as follows: Group 1 (20 participants with healthy gingiva), Group 2 (20 participants with gingivitis), and Group 3 (20 participants with chronic periodontitis). Clinical parameters such as gingival index, periodontal index, probing pocket depth, and clinical attachment level were assessed. GCF and blood samples were taken from these patients and assessed for the mRNA expression of ezrin using real-time polymerase chain reaction. Results: The expression and mean relative quantification of mRNA expression of ezrin in GCF and blood were higher for periodontitis (18.32 ± 8.398, 19.34 ± 9.487) when compared to that of gingivitis (5.34 ± 3.609, 5.48 ± 4.428) and healthy individuals (2.33 ± 0.643, 3.47 ± 1.923) and they positively correlated with the clinical parameters. Conclusion: The increased expression of ezrin can be considered as a good indicator to assess the inflammatory activity in periodontitis and gingivitis.

Surgical management of maxillary trauma in pediatric special needs patient using modified cap splint.

Pediatric maxillofacial trauma is a rare entity, which is primarily the reason for an individual surgeon's inexperience in managing such injuries. More so, maxillary injuries are infrequent. Pediatric maxillofacial injuries are usually a result of blunt force trauma such as falls, motor vehicle accidents, bicycle injuries, sports-related injuries, assault, and child abuse. The atypical pattern of facial injuries in the pediatric population necessitates each surgeon to approach individual cases with a unique and innovative technique of management, while still following the basic principles of surgical management of maxillofacial injuries. Since facial trauma and surgical interventions both have the potential to lead to disturbance in growth and development, management should be as conservative as possible. The foundation of any surgical intervention must be developed keeping in perspective, the future growth, and development of dentofacial structures. Pediatric facial trauma management is in itself a disconcerting situation for a maxillofacial surgeon, but when a special needs child is involved it becomes an even more perplex decision. We present a case of maxillary trauma in a pediatric patient with global developmental delay, the treatment dilemma, and a review of current literature.

Surgical Management of Mandibular Subcondylar Fractures Under Local Anesthesia: A Proposed Protocol.

PURPOSE: The optimal treatment for adult mandibular condylar fractures (MCFs) has largely shifted in favor of open reduction and rigid internal fixation. However, a sizeable portion of these injuries are still being treated in a closed manner based on old literature, convenience, results deemed acceptable, and lesser associated morbidity. Most MCFs with multiple associated facial traumas are appropriately treated under general anesthesia (GA). However, some selected isolated MCFs or those with minimal associated mandibular or low midfacial fractures can be treated optimally with patients under local anesthesia following a protocol presented in this article, thus expediting and simplifying their management. The purpose of this study was to develop a safe, sound, effective protocol for routine surgical management of mandibular subcondylar fractures under local anesthesia. PATIENTS AND METHODS: We carried out a prospective clinical study to assess the feasibility of operating on MCFs with patients under local anesthesia. Seven patients with MCFs and other associated facial fractures underwent surgery after careful case selection following our proposed protocol. The outcome variables were 1) duration of the procedure, 2) intraoperative pain assessed by a visual analog scale, 3) fracture reduction assessed by measuring the preoperative and postoperative average fracture gap, 4) presence of malocclusion preoperatively and postoperatively, 5) deviation on mouth opening, and 6) maximal mouth opening. RESULTS: The mean duration of the procedure was 35.14 minutes, and the mean rating of intraoperative pain or discomfort was 0.57 as reported on the visual analog scale by the patients. Mean mouth opening improved from 17.1 to 40.5 mm, whereas deviation on opening improved from 4.4 to 0.28 mm. The average fracture gap was reduced from 6.32 to 0.97 mm. CONCLUSIONS: The presented protocol is a straightforward, efficient, safe, cost-effective tool for operating on MCFs, avoiding GA with its attendant risks and complications, that can be used routinely, as well as in patients for whom GA is deemed unsuitable.
