Novel Index Combining Pan-Immune-Inflammatory Index and Hemoglobin Levels (PIV/Hb) Predicts Trismus Rates Efficiently after Chemoradiotherapy in Locally Advanced Nasopharyngeal Cancer.

Purpose: To evaluate the predictive potency of a novel index combining the pan-immune-inflammatory index and hemoglobin levels (PIV/Hb) for the prevalence of radiation-induced trismus (RIT) in patients with locally advanced nasopharyngeal cancer (LA-NPC) receiving concurrent chemoradiotherapy (CCRT). Methods: Data from 228 LA-NPC patients were retrospectively examined. Maximum mouth openings (MMO) were measured to confirm the presence of RIT, defined as MMOs ≤35 mm. Complete blood test results from the first day of CCRT were used to calculate PIV/Hb levels. A potential relationship between pretreatment PIV/Hb and the RIT status was evaluated using receiver operating characteristic (ROC) curve analysis. Results: Post-CCRT RIT was diagnosed in 20.2% of the patients. The ROC curve analysis determined 68.4 g/dL as the ideal PIV/Hb cutoff that effectively divided patients into two distinct groups (area under the curve: 94.7%; specificity: 86.4%; sensitivity: 87.4%). RIT was significantly more prevalent in the PIV/Hb > 68 group than in the PIV/Hb < 68 group (58.8% vs. 3.8%; P < 0.001). Multivariate logistic regression analysis showed that a pre-CCRT PIV > 68 was independently associated with significantly higher rates of RIT. Conclusion: Higher pretreatment levels of the novel PIV/Hb index predict increased RIT rates following definitive CCRT for LA-NPCs.

Fibrodysplasia ossificans progressiva complicated with post traumatic and infectious myositis ossificans in masseter: A case report.

RATIONALE: Myositis ossificans (MO) is characterized by benign heterotopic ossificans in soft tissues like muscles, which can be classified into nonhereditary MO and fibrodysplasia ossificans progressiva (FOP). Nonhereditary MO is characterized by ossification of the soft tissues after acute or repetitive trauma, burns, or surgical intervention. FOP is a rare and crippling disease characterized by congenital malformation of the big toe and heterotopic ossification in muscle. The majority of FOP's musculoskeletal traits are associated with dysregulated chondrogenesis. The diagnosis is mainly based on clinical manifestation, imaging examination, and genetic analysis. There is still no effective treatment to cure or slow its progression. The best approach remains early diagnosis, conservative drug treatment, and injury prevention to avoid local ossification. PATIENT CONCERNS: A 34-year-old male presented at our hospital because of trismus caused by ossification of the masseter muscle. In addition, he had serious stiffness and multiple bony masses throughout the body, which led to limited movement. DIAGNOSES: Based on the clinical manifestation of movement restriction, characteristic radiographic images of ossification of soft tissues, the genetic test showing a heterozygous molecule (c.974G > C, p.G325A) of the activin A receptor type I, the patient was diagnosed as FOP complicated with localized MO in masseter after trauma and infection. INTERVENTIONS: The patient underwent the surgical resection of ossification in the masseter muscle, he was instructed to insist on mouth-opening exercises and take glucocorticoids and nonsteroidal anti-inflammatory medications after surgery. OUTCOMES: The symptoms of trismus are relieved, and eating can be basically achieved after surgery, while the symptoms of trismus recurred 2 years later. LESSONS: Although FOP has unique clinical manifestations, its diagnosis may be difficult because of its rarity. Gene analysis is the main standard for diagnosis, while patients with different genotypic variations may show different clinical symptoms. Therapeutic interventions are still supportive and preventive, and surgery is not recommended except under certain circumstances.

One-Stage Bilateral Severe Trismus Reconstruction: Simultaneous Utilization of Free Anterolateral Thigh and Tensor Fascia Latae Flaps From a Single Donor Thigh: Report of Three Cases.

Bilateral trismus associated with oral cancer was commonly occurred in those who had received surgical intervention and radiotherapy. Complete release of bilateral fibrotic tissues followed by free flaps reconstruction was the main current surgical intervention. However, reconstructions of both defects mostly needed to harvest two flaps from different donor sites were time-consuming and increasing morbidities. Herein, we presented three cases who undergone modified reconstructive method by harvesting the anterolateral thigh (ALT) flap and tensor fascia latae (TFL) flap simultaneously from the same donor site. Trismus release was performed including resection of the buccal part and fibrotic tissue, myotomy of the masticatory and medial pterygoid muscles, and bilateral coronoidectomy. Case 1, a 52 years-old man, with severe trismus as the interincisal distance (IID) was about 0 mm. He undergone a combined 12 × 7.5 cm ALT and 11 × 6 cm TFL flap reconstruction from a single-donor thigh. The IID apparently increased to 37 mm after 1-year follow-up. Case 2, a 64 years-old man, went through a combination of 6 × 7 cm ALT and 6 × 6 cm TFL flap reconstruction from unilateral thigh for severe trismus. The IID significantly improved from 10 mm to 30 mm after one and a half-year follow-up. Case 3, a 53 years-old woman, with IID was around 0 mm before the surgery. A combined 9 × 3 cm ALT and 9 × 3 cm TFL flap reconstruction was performed as the IID enhanced to 20 mm after 6 months follow-up. This reconstruction method using ALT and TFL flaps harvested from a single-donor thigh simultaneously could be suitable for patients with bilateral severe trismus.

Decreased Rates of Radiation-induced Trismus and Lowered Mastication Structure Doses in Patients Treated for Head and Neck Cancer During the Last Two Decades.

AIMS: To investigate how absorbed doses to mastication structures in modern radiotherapy (RT) technique for head and neck cancer (HNC) compared with earlier RT techniques and with published trismus tolerance doses. To compare the incidence of radiation-induced trismus by earlier and newer RT techniques. MATERIALS AND METHODS: This study investigated two HNC patient cohorts treated with RT in 2007-2012 (three-dimensional conformal radiotherapy [3DCRT] and/or intensity-modulated radiotherapy [IMRT]; n =121 [Cohort 1]) and 2017-2020 (volumetric-modulated arc therapy [VMAT]; n =124 [Cohort 2]). All patients underwent RT without mastication structure-sparing intent, had normal mouth-opening ability before RT, and were prospectively assessed. Trismus was defined as the maximal interincisal opening ≤35 mm at any follow-up (3-, 6-, and 12-months post-RT). The temporomandibular joints (TMJs), masseter, and medial/lateral pterygoid muscles were delineated on the planning CT:s. Mean doses were compared between cohorts, and evaluated with respect to published trismus tolerance doses. P values ≤ 0.05 indicated statistical significance. RESULTS: Within 12 months post RT, 74/121 (61%) of patients in Cohort 1 had experienced trismus compared to 11/124 (9%) in Cohort 2. Averaged mean doses (±S.D.) for the masseter muscles were 35.2±8.3 Gy in Cohort 1 and 20.2±8.7 Gy in Cohort 2 (P <0.001). Corresponding numbers were 19.1±16.2 and 4.3±4.3 Gy for the TMJs, 53.7±10.1 and 40.2±16.8 Gy for the medial pterygoid muscles, and 29.2±18.7 and 9.2±8.4 Gy for the lateral pterygoid muscles (all P <0.001). Masseter muscle doses were below tolerance doses in 23% of patients in Cohort 1 compared with 90% in Cohort 2. The corresponding numbers were 52% and 96% for the TMJs, 8% and 36% for the medial pterygoid muscles and 72% and 100% for the lateral pterygoid muscles. CONCLUSION: Mastication structure mean doses by more recent RT techniques were generally below proposed tolerance doses, with dose reductions of 10-20 Gy compared with earlier techniques. Modern RT without mastication-structure-sparing intent resulted in below 10% of HNC patients experiencing trismus compared with 60% treated with earlier techniques.

Analysing inflammatory responses after mandibular third molar extraction: a comparison of suture-less and multiple suture techniques.

PURPOSE: This study aims to compare the outcomes of suture-less and multiple suture closure methods on postoperative pain, swelling, and trismus, and associated complications. MATERIALS AND METHODS: This prospective, randomized clinical trial was conducted at the Department of Oral & Maxillofacial Surgery, Goa Dental College & Hospital. Inclusion criteria encompassed subjects aged between 17 and 55 years, classified as American Society of Anaesthesiologists (ASA) I, with asymptomatic impacted third molars falling within the moderately difficult impaction range (Pederson's difficulty index: 5-7). Study excluded individuals classified as ASA II, III, or IV, those with known or suspected allergies to the anaesthetic solution, immunocompromised patients, and individuals taking medications that could affect healing. Pregnant or lactating females and those with a history of bleeding disorders were also excluded. Wound closure methods were compared: Group A underwent primary closure with silk sutures, while Group B had suture-less closure. Subjects were allocated to the specific groups using a simple randomization method. This involved using a lottery-based random sequence to assign each participant to either Group A or Group B. Pain intensity, facial swelling, and trismus were key outcomes. Secondary outcomes included lingual nerve sensation and postoperative complications. Demographics factors, surgical details, radiographic and perioperative data, and physiological parameters were considered. Non-parametric tests and parametric test (repeated measure ANOVA) were employed. Statistical significance was set at P < 0.05. RESULTS: Among 101 participants, both closure techniques exhibited similar outcomes in pain, swelling, and lingual nerve function. However, suture-less closure resulted in significantly less trismus and fewer cases of delayed wound healing. CONCLUSIONS: Suture-less method after surgical removal of third molar may reduce trismus compared to multiple sutures. While pain, swelling, and lingual nerve function management were comparable.

Effect of a Single Dose of Deflazacort on Postoperative Pain, Swelling, and Trismus after Impacted Lower Third Molar Surgery: Randomised Clinical Trial.

Background and Objectives: The aim of this study was to investigate the efficacy of a single preoperative dose of deflazacort on pain, swelling, and trismus after impacted lower third molar surgery. Materials and Methods: This randomised, prospective, double-blind, split-mouth clinical study included 26 healthy individuals with bilaterally impacted lower third molars. Group 1 was given a placebo (single-dose vitamin C tablet), and group 2 was given a single 30 mg dose of deflazacort 1 h prior to surgery. Pain was evaluated using the visual analogue scale for 1 week postoperatively. Oedema (in mm) and trismus (in mm) were evaluated preoperatively and on postoperative days 2 and 7. The Mann-Whitney U test was applied for group analyses. p values < 0.05 were considered statistically significant. Results: Postoperative pain scores were significantly lower in the deflazacort group at the 6th and 12th hours after surgery (p < 0.05). There were no significant differences in trismus between the groups at any time point (p > 0.05). There was less oedema in the deflazacort group on postoperative days 2 and 7, without any statistically significant difference (p > 0.05). Conclusions: A single preoperative dose of 30 mg deflazacort was found to be clinically effective in reducing pain and oedema after extraction of impacted lower third molars.

Definitive radiotherapy and trismus in HNC patients: A critical review.

INTRODUCTION: Trismus is a potentially critical morbidity following curative-intended radiotherapy in head and neck cancer patients. However, in this setting, evidence regarding this side effect remains to be fully defined, particularly in terms of dosimetric parameters. MATERIALS AND METHODS: Key references were derived from a PubMed query. Hand searching and clinicaltrials.gov were also used. RESULTS: This paper contains a narrative report and a critical discussion of the evidence on radiation-induced trismus in the literature, particularly the dosimetric concerns. CONCLUSIONS: The treatment goal should be to maintain high cure rates and limit the onset of complications. Further evaluations of dosimetric measures and clinical outcomes are warranted to identify patients at higher risk to target treatment tailoring.

Rare mandibular condition presenting as trismus: an exploration of IgG4-related disease.

A woman in her 30s presented with a 12-month history of reduced mouth opening and swelling on the right side of her mandible. The swelling was non-tender and firm on palpation. The swelling began to increase in size after the extraction of her carious wisdom tooth. Histopathological and serological examinations confirmed the diagnosis of IgG4-related disease, manifested as a mass in the mandible. The patient was prescribed oral corticosteroids at a tapering dosage over 8 weeks. After 3 months, there was an improvement in the patient's mouth opening and a reduction in the size of the swelling. The patient remains in follow-up care. Including IgG4-related disease in the list of potential diagnoses for oral soft tissue masses is crucial, given their positive response to medical treatment, highlighting the significance of an accurate diagnosis to prevent unnecessary surgery, with oral lesions potentially serving as early indicators before multiorgan complications arise.

Effectiveness of mHealth intervention for trismus exercise in patients with head and neck cancer undergoing proton and heavy ion therapy: a randomized control trial.

PURPOSE: This study aimed to compare the effects of a mobile health intervention based on social cognitive theory with standard care on maximal mouth opening, exercise compliance, and self-efficacy in patients receiving proton and heavy ion therapy for head and neck cancer. METHODS: This open-label, parallel-group, randomized, superiority trial involved a self-developed "Health Enjoy System" intervention. We assessed maximal mouth opening, exercise compliance, and self-efficacy at baseline (T0), post-treatment (T1), and at 1 month (T2) and 3 months (T3) after radiotherapy. Generalized estimating equations were used to analyze differences between the groups over time, with results reported as P values and 95% confidence intervals (CIs). RESULTS: The study included 44 participants. At T3, the intervention group showed a 6 mm greater increase in maximal interincisal opening than the control group (mean difference = 6.0, 95% CI = 2.4 to 9.5, P = 0.001). There was also a significant difference in exercise compliance between the groups (mean difference = 31.7, 95% CI = 4.6 to 58.8, P = 0.022). However, no significant difference in self-efficacy was found between the groups. CONCLUSION: This study demonstrated that an mHealth intervention incorporating behavior change theory could effectively enhance or maintain maximal mouth opening in patients undergoing proton and heavy ion therapy for head and neck cancer in China. This approach provides valuable support during and after treatment. TRIAL REGISTRATION: ChiCTR: ChiCTR2300067550. Registered 11 Jan 2023.

Oral management for a patient with trismus accompanied by Isaacs' syndrome: a case report.

BACKGROUND: Isaacs' syndrome, also known as neuromyotonia or peripheral nerve hyperexcitability, is a rare disorder that affects the peripheral nervous system. Clinical findings include cramps, fasciculations, and myokymia; however, there are few reports of dental treatment for trismus. CASE PRESENTATION: A patient with trismus due to Isaacs' syndrome experienced swelling and pain in the gingiva surrounding his right lower first molar. He was diagnosed with chronic apical periodontitis by a dentist near his home. However, the patient was informed that dental treatment and medication could not be administered because of the presence of Isaacs' syndrome, and he visited the Geriatric Dentistry and Perioperative Oral Care Center at Kyushu University Hospital 2 weeks later. The patient's painless mouth-opening distance (between incisors) was 20 mm at that time, and medication, including amoxicillin capsules and acetaminophen, was administered because the dental extraction forceps or endodontic instruments were difficult to insert into the oral cavity for treatment. Two months after his initial visit, the patient visited us complaining of pain in the same area. However, he had recently undergone plasmapheresis treatment in neurology to alleviate limited mouth opening and systemic myalgia, resulting in a pain-free mouth-opening distance of approximately 35 mm. During this temporary period in which he had no restriction in mouth opening, we performed tooth extraction and bridge restoration on the mandibular right first molar and created an oral appliance for sleep bruxism. CONCLUSIONS: Plasmapheresis therapy transiently reduced trismus, rendering dental interventions feasible, albeit temporarily. This case report underscores the importance of close collaboration between neurologists and dentists who encounter similar cases while furnishing valuable insights to inform dental treatment planning.

Dysphagia and Trismus After Tooth Extraction : Clinical Conondrum.

Clinicians should consider disorders of masticatory muscle including lateral pterygoid muscle as a differential diagnosis in patients presenting with dysphagia and trismus after tooth extraction.

Systematic review of adherence to swallow and trismus exercises during radiation therapy for head and neck cancer.

Understanding the barriers and facilitators for prophylactic swallowing and trismus exercises for patients undergoing radiation to the head and neck may help exercise adherence. The analysis reviews all published reports of exercise adherence with a critical appraisal following PRISMA guidelines. A total of 137 potential papers were identified; 20 studies met the inclusion criteria. The most commonly reported facilitators for swallowing and trismus exercises were regular clinician contact and online resources to reinforce instructions, set goals, and manage radiation toxicities. Social support and perceived benefit from exercises were also reported to be of help. The most common barriers to exercise were radiation toxicities, anxiety, feeling overwhelmed with information, and not understanding the reason for the exercises. Understanding facilitators and barriers to adherence is critical when designing exercise interventions for patients undergoing radiation for head and neck cancer.

Throat packing via nasopharyngeal airway for severe trismus cases requiring surgical intervention under general anesthesia: A simplified and innovative approach.

Throat packing is essential in oral and maxillofacial surgeries to prevent blood and tissue debris aspiration, reducing postoperative complications. Traditional oral route methods are often inadequate, especially in severe trismus cases like Oral Submucous Fibrosis (OSMF), TMJ Ankylosis, and post-traumatic conditions due to limited mouth opening. This study introduces a novel technique using a nasopharyngeal airway (NPA) for throat packing. The method involves inserting a hemostatic dressing through an NPA, ensuring minimal invasiveness and effective airway management. Proper positioning is confirmed with a laryngoscope or fiberoptic scope, and the dressing is secured to prevent dislodgement. This technique is easy, reproducible, and less injurious compared to traditional methods. At our center, throat packing via NPA was performed on 35 patients undergoing surgery under general anesthesia, resulting in high satisfaction and no reported complications.

IS THE PHOTOBIOMODULATION THERAPY EFFECTIVE IN CONTROLLING POST-SURGICAL SIDE EFFECTS AFTER THE EXTRACTION OF MANDIBULAR THIRD MOLARS? A SYSTEMATIC REVIEW AND META-ANALYSIS.

OBJECTIVES: The extraction of third molars is one of the most performed surgical procedures in oral and maxillofacial surgery. Pain, oedema, and trismus are the most frequently complications related in the surgical postoperative period. The literature has indicated PBM as a potential adjuvant method to reduce these complications. The aim of this review and meta-analysis is evaluate the PBM, as an optimal method to improve patient experience and minimize postoperative morbidity. Additionally, we seek to determine which wavelength, site, and frequency of application are most effective. METHODS: This review was registered in PROSPERO (CRD42023429966) and followed PRISMA guidelines. The search was carried out in the main databases, PubMed/MEDLINE, Cochrane Library, Embase, Scopus, and Lilacs, including reviews in the most important journals in the area of oral surgery and laser applied to oral surgery. In addition, all article references and also gray literature were reviewed. After the studies selection, the relevant data was collected. All the studies were randomized controlled trials and the patients were allocated into two groups: active PBM and inactive PBM. The statistical analysis was carried out using Stata v.16, and the methodological quality and risk of bias were assessed by the Jadad scale and RoB 2.0, respectively. RESULTS: Where included 22 studies and 989 subjects, to all with a minimum follow-up of 7 days. Pain and oedema showed statistically significant results in favor to the active PBM group. Especially when laser applied in infrared mode, for pain and oedema at 48 h, MD = -1.80 (CI95% -2.88, -0.72) I²â€¯= 92.13% and MD = -1.45 (CI95% -2.42, -0.48) I²â€¯= 65.01%, respectively. The same is not true for trismus at 48 h, MD = 0.07 (CI95% -0.06, 0.21) I²â€¯= 3.26%. The meta-analysis also presented results in respect of laser site of application and number of PBM sessions. CONCLUSIONS: PBM with infrared laser, in a combination intraoral and extraoral application, in one session in the immediate postoperative period, has been shown to be effective to achieve the objectives of reducing pain and oedema after third molar extraction.

Exercise adherence for patients with trismus after head and neck cancer treatment.

BACKGROUND: Head and neck cancer treatment often leads to trismus, a condition characterized by limited mouth opening. Exercise-based therapy is the most common intervention but there are no clear guidelines as to the optimal exercise regimen. Restorabite™ is a portable and force-regulated trismus device designed to enhance exercise adherence. This study explores the adherence to exercises using Restorabite™ in head and neck cancer patients with trismus and identifies facilitators and barriers to exercise therapy. MATERIALS AND METHODS: Mixed-methods, prospective cohort study undertaken at a quaternary oncology hospital, in Sydney Australia involving participants diagnosed with head and neck cancer diagnosed with trismus (maximal incisal opening under 35 mm). Patients underwent a 10-week individualized trismus program using Restorabite™ with weekly speech pathology reviews. Exercise adherence was tracked through categorized descriptors. Data were collected prospectively at baseline, during 10 weeks of therapy with Restorabite™, and at 6- and 12-month post-trismus exercise. Participants described facilitators of trismus therapy, and barriers to completing the prescribed exercises. Clinical documentation of these responses was then analyzed using content analysis. RESULTS: One-hundred and thirty-five participants were recruited. During the intervention 69% (n = 93) exercised as recommended, 24% (n = 32) exercised less, and 7% (n = 10) exercised more than recommended. At 6 months post-intervention, 55.5% (n = 75) exercised as recommended, 38.5% (n = 52) exercised less, and 4% (n = 6) exercised more. At 12 months, 36% (n = 49) exercised as recommended, 48% (n = 62) exercised less, and 11% (n = 15) exercised more. MIO increased from a mean of 18.6 mm at baseline, to 30.1 mm at the end of the 10-week intervention. This was maintained at 6 and 12 months (31.7 and 32.1 mm, respectively). Adherence to the exercise program was associated with greater improvement in maximum interincisal opening (p < 0.001). Facilitators of adherence included intrinsic motivation, device portability, perceived functional change, and external support tools. Barriers included cancer treatment toxicities, competing priorities, and health challenges. Positive outcomes included functional improvements, while negative outcomes included increased pain. CONCLUSIONS: Seventy-six percent of patients prescribed Restorabite™ performed trismus exercises at or more than the recommended frequency. Facilitators and barriers identified provide insights into factors influencing adherence. Future research should involve comparative studies that compare the adherence and effectiveness of different exercise programs.

Postradiation trismus in head and neck cancer survivors: a qualitative study of effects on life, rehabilitation, used coping strategies and support from the healthcare system.

PURPOSE: This study aimed to explore the experiences of head and neck cancer (HNC) survivors with postradiation trismus, specifically how oncological treatment affected their lives, rehabilitation, use of coping strategies, and healthcare experiences. METHODS: A qualitative descriptive approach was used and semi-structured interviews of 10 HNC survivors with postradiation trismus were conducted 6-30 months after completing oncological treatment. The interviews were transcribed verbatim and analyzed by qualitative content analysis. RESULTS: The analysis of interviews yielded four main categories: Bodily symptoms, Effects on life, Support from the healthcare system, and Strategies to handle life and symptoms. Participants reported ongoing problems with xerostomia, dysgeusia, eating, and limited physical fitness. Pain related to trismus was not a major issue in this cohort. Participants expressed limitations in their social lives due to their eating difficulties, yet a sense of thankfulness for life and overall satisfaction with the healthcare they received. Psychological and practical coping strategies developed by the participants were also revealed. CONCLUSION: The results highlight areas of unmet need among HNC survivors that healthcare providers can target by establishing multi-professional teams dedicated to individualizing post-cancer rehabilitation care.

Restorabite™: Phase II trial of jaw stretching exercises using a novel device for patients with trismus following head and neck cancer.

Patients treated for oral cancer, may experience restricted mouth opening (trismus). Barriers such as cost have limited the utilization of traditional jaw stretching devices, and consequently, patients experience problems with swallowing, oral care, communication, and cancer surveillance. The safety and efficacy of Restorabite™, a new device designed to overcome these barriers, is evaluated prospectively over 12 months. This phase II investigator-led trial included patients with chronic trismus underwent 10-weeks of trismus therapy using Restorabite™. Safety, adherence, changes in mouth opening, and patient-reported outcomes are presented. 114/120 participants with trismus completed the intervention, and 104 had their progress monitored for 12 months. Thirteen participants withdrew due to tumour recurrence. At the completion of the intervention, mouth opening improved by 10.4 mm (p < .001). This increased to 13.7 mm at 12 months (p < .001). Patient reported outcome all significantly improved and 47 participants were no longer classified as having trismus. There were no serious treatment related adverse events. In patients with trismus following head and neck cancer treatment, a 10-week programme of jaw stretching exercises using Restorbite™ safely improves mouth opening and associated quality of life outcomes with high adherence and the benefits are maintained for 12-months.

How effective are concentrated growth factor and injectable platelets in reducing complications following impacted third molar surgery?

OBJECTIVES: This study examined the impact of injectable platelet-rich fibrin (iPRF) and concentrated growth factor on postoperative pain, edema, trismus, and quality of life in impacted mandibular third molar surgery. The primary aim of this study was to minimize common sequelae following third molar surgery by using iPRF and concentrated growth factor. The secondary objective was to compare the postoperative effects of these products. METHOD AND MATERIALS: This study represents a single-center, randomized prospective clinical trial conducted at the Ordu University Faculty of Dentistry. It involved patients who underwent third molar surgery for various reasons between July and October 2022. The predictor variables were the use of concentrated growth factor and i-PRF. They were categorized as concentrated growth factor, i-PRF, and control groups. The outcome variables include pain levels and analgesic consumption measured on a visual analog scale, distances between predetermined anatomical points, maximum mouth opening capacity, and data from the postoperative symptom severity (PoSSe) scale. Some statistical tests were performed with a 95% confidence interval, which was considered significant. RESULTS: Total analgesic use was notably lower in the concentrated growth factor group (P = .044). Concentrated growth factor and iPRF outperformed the control group in all edema measurements by postoperative day 7 (tragus-pogonion, lateral canthus-angulus, tragus-commissura; P < .05). Concentrated growth factor significantly reduced trismus on days 2 and 7. Quality of life was notably higher in the concentrated growth factor group than in the control group (P = .026), although iPRF group differences were not significant. CONCLUSION: The results indicate that concentrated growth factor has a limited impact on postoperative pain, but significantly reduces edema, trismus, and enhances quality of life. The iPRF group experienced positive effects on pain, edema, and trismus, although the statistically significant differences observed with concentrated growth factor highlight its potential for use instead of iPRF after third molar surgery. An increased sample size is essential for more comprehensive results.
