Ultrasound in Causes of Stridor in Children.

Airway ultrasound (US) is an easily available, portable, radiation-free imaging modality for quick, non-invasive, dynamic evaluation of the airway without sedation. This is useful in children with stridor, which is an emergency due to upper airway obstruction requiring immediate management. Several causes of stridor including laryngomalacia, laryngeal cyst, subglottic hemangioma, vocal cord palsy, and lymphatic malformations can be evaluated accurately. Thin musculature and unossified cartilages in children provide a good acoustic window. Thus, airway US is valuable, but underutilized for the evaluation of children with stridor. In this case-based review, we describe the technique, indications, anatomy, and pathologies on airway US.

Endemic pediatric fungal infections in India: clues to diagnosis.

This review is intended to familiarize readers with an emerging group of fungal infections that mostly manifest in immunocompetent individuals. This group was initially considered endemic to the tropics, but increasing worldwide prevalence has been reported. The organisms have been divided into dominant non-invasive forms and dominant invasive forms for ease of understanding. The non-invasive organisms include the group Entomophthoromycota, under which two genera Basidiobolus and Conidiobolus, have been identified as human pathogens. They present with plaques in the extremities and rhinofacial region, respectively. The invasive organisms are dematiaceous fungi (phaeohypomycosis), which includes Cladophialophora and Exophiala among others. They cause invasion of deep tissues, with the central nervous system being the most common target. The mycology, epidemiology, diagnosis, and treatment options have been summarized in brief. The clinical presentation, imaging manifestations, differentiation from other common infections and malignancies that show similar features have been detailed.

Vascular anomalies: diagnostic features and step-wise approach.

The first part of this review article emphasized correct nomenclature, classification systems, and imaging algorithm of vascular anomalies. The second part of the review discusses the individual entities, highlighting the characteristic clinico-radiological features of the commonly encountered ones. A step-wise algorithmic approach is also proposed for the evaluation of a suspected case of vascular anomaly.

Vascular anomalies: nomenclature, classification, and imaging algorithms.

There is a lot of ambiguity in the usage of correct terminology in the description of vascular malformations and tumors. Hemangioma and arteriovenous malformation (AVM) are the most commonly used terms and are the mostly incorrectly used as well! The aim of this review article was to lay out the correct nomenclature and describe the correct usage for the physicians and radiologists involved in diagnosing and managing these lesions. We describe the various classification systems which have been devised to define the multiple entities included under vascular anomalies. The latest classification system that should be adhered to is per the International Society for the Study of Vascular Anomalies, approved at the 20th ISSVA Workshop held in Melbourne in April 2014, last revised in May 2018. The main features of the latest revision have been highlighted. This classification, however, does not list the diagnostic clinico-radiological features for each entity. In addition, guidelines regarding the appropriate use of available imaging modalities are lacking in the literature. We, hereby, aim to address these pertinent issues in this review article.

Chemotherapy response evaluation using diffusion weighted MRI in Ewing Sarcoma: A single center experience.

BACKGROUND: Non-invasive biomarkers for early chemotherapeutic response in Ewing sarcoma family of tumors (ESFT) are useful for optimizing existing treatment protocol. PURPOSE: To assess the role of diffusion-weighted magnetic resonance imaging (MRI) in the early evaluation of chemotherapeutic response in ESFT. MATERIAL AND METHODS: A total of 28 patients (mean age = 17.2 ± 5.6 years) with biopsy proven ESFT were analyzed prospectively. Patients underwent MRI acquisition on a 1.5-T scanner at three time points: before starting neoadjuvant chemotherapy (baseline), after first cycle chemotherapy (early time point), and after completion of chemotherapy (last time point). RECIST 1.1 criteria was used to evaluate the response to chemotherapy and patients were categorized as responders (complete and partial response) and non-responders (stable and progressive disease). Tumor diameter, absolute apparent diffusion coefficient (ADC), and normalized ADC (nADC) values in the tumor were measured. Baseline parameters and relative percentage change of parameters after first cycle chemotherapy were assessed for early detection of chemotherapy response. RESULTS: The responder:non-responder ratio was 21:7. At baseline, ADC ([0.864 ± 0.266 vs. 0.977 ± 0.246]) × 10-3mm2/s; P = 0.205) and nADC ([0.740 ± 0.254 vs. 0.925 ± 0.262] × 10-3mm2/s; P = 0.033) among responders was lower than the non-responders and predicted response to chemotherapy with AUCs of 0.6 and 0.735, respectively. At the early time point, tumor diameter (27% ± 14% vs. 4.6% ± 10%; P = 0.002) showed a higher reduction and ADC (75% ± 44% vs. 52% ± 72%; P = 0.039) and nADC (81% ± 44% vs. 48% ± 67%; P = 0.008) showed a higher increase in mean values among responders than the non-responders and identified chemotherapy response with AUC of 0.890, 0.723, and 0.756, respectively. CONCLUSION: Baseline nADC and its change after the first cycle of chemotherapy can be used as non-invasive surrogate markers of early chemotherapeutic response in patients with ESFT.

Intraoral Ultrasound in Early Stage Tongue Carcinoma.

Preoperative assessment of depth of invasion (DOI) is critical in the surgical management of early stage carcinoma tongue. Intraoral ultrasound (IOUS) has been recently described as a cost-effective alternative to MRI in the accurate measurement of DOI. We describe the technique of IOUS in different types of lesions (surface, ulcerative, and exophytic); and provide key imaging pearls for the routine use of this novel ultrasound application.

Split-bolus, single-phase contrast enhanced CT: a one-stop shop for invasive fungal sinusitis.

Contrast-enhanced magnetic resonance imaging is considered the imaging modality of choice for invasive fungal sinusitis (IFS); however, it is not feasible to perform emergency CEMRI especially in the setting of COVID-19. The CECT protocol for evaluation of suspected IFS can be modified by using split-bolus, single-phase CT as it provides an optimal soft tissue demonstration of sinonasal disease; extrasinus spread to orbit, and intracranial involvement along with simultaneous opacification of the internal carotid artery and cavernous sinus. The extent of bone erosion can also be well delineated on the multiplanar reconstructions (MPRs) in the bone window. Further a structured reporting format can help provide optimal surgical guidance in cases of IFS.

Effect of rehabilitation by using the shortened dental arch concept on the thickness of the masseter muscle and occlusal force: A pilot study.

STATEMENT OF PROBLEM: Knowledge of the effect of a shortened dental arch on masseter muscle thickness and occlusal force is sparse but could help clinicians understand how a shortened dental arch might affect the stomatognathic system. PURPOSE: The purpose of this pilot clinical study was to evaluate and compare the masseter muscle thickness and occlusal force of participants rehabilitated by using a shortened dental arch with matched completely dentate individuals. MATERIAL AND METHODS: Twelve partially edentulous participants with a minimum of 1 posterior occluding pair on each side of the arch were enrolled in the study. The mandibular arch of these participants was rehabilitated by using a single posterior mandibular implant crown (group S). The maxillary arch of all participants in group S was intact. Masseter muscle thickness (cm) and occlusal force (N) were recorded before (T1) and 6 months after implant rehabilitation (T2) for each participant. Twelve participants were selected as controls (group C). They were matched for age, sex, height, and weight with group S and evaluated for masseter muscle thickness and occlusal force. Masseter muscle thickness was evaluated by using ultrasonography during the rest position and maximum volumetric clenching. Occlusal force was measured with an occlusal force measuring appliance. All recordings were done for the left and right sides of the arch. Descriptive analysis was followed by comparison between groups and within group S by using the paired t test (α=.05). RESULTS: Higher masseter muscle thickness and higher occlusal force were observed in group C than in group S before and after rehabilitation. An increase in masseter muscle thickness in the rest position and in maximum volumetric clenching was observed within group S after rehabilitation. Before rehabilitation, a difference in the masseter muscle thickness between group S and group C was statistically significant for the left side at the rest position (P=.017) and during maximum volumetric clenching (P=.016). After rehabilitation, the difference between group S and group C was not statistically significant for masseter muscle thickness at the rest position (P=.890 for right side and P=.555 for left side) and during maximum volumetric clenching (P=.109 for right side and P=.755 for left side). The difference in occlusal force between group S and group C was statistically significant for the right side and left side (P<.001) before rehabilitation and statistically not significant after rehabilitation (P=.161 for the right side and P=.134 for the left side). CONCLUSIONS: Rehabilitation following the concept of a shortened dental arch increased masseter muscle thickness and occlusal force in partially edentulous individuals, making the masseter muscle thickness and occlusal force comparable with those of a completely dentate arch.

Non-coding RNA in idiopathic interstitial pneumonia and Covid-19 pulmonary fibrosis.

Pulmonary fibrosis is the key feature of majority of idiopathic interstitial pneumonias (IIPs) as well as many patients with post-COVID-19. The pathogenesis of pulmonary fibrosis is a complex molecular process that involves myriad of cells, proteins, genes, and regulatory elements. The non-coding RNA mainly miRNA, circRNA, and lncRNA are among the key regulators of many protein coding genes and pathways that are involved in pulmonary fibrosis. Identification and molecular mechanisms, by which these non-coding RNA molecules work, are crucial to understand the molecular basis of the disease. Additionally, elucidation of molecular mechanism could also help in deciphering a potential diagnostic/prognostic marker as well as therapeutic targets for IIPs and post-COVID-19 pulmonary fibrosis. In this review, we have provided the latest findings and discussed the role of these regulatory elements in the pathogenesis of pulmonary fibrosis associated with Idiopathic Interstitial Pneumonia and Covid-19.

Efficacy of Intrabronchial Voriconazole Instillation for Inoperable Pulmonary Aspergilloma: A Pilot Randomized Controlled Trial.

BACKGROUND: Endobronchial administration of voriconazole is a potential therapeutic option for inoperable aspergilloma. OBJECTIVE: This study aimed to assess the efficacy of endobronchial instillation of voriconazole for inoperable pulmonary aspergilloma. METHOD: Patients with mild to moderate hemoptysis, due to inoperable aspergilloma, were randomized to receive either medical therapy (MT) alone or bronchoscopic instillation of voriconazole with MT and followed up till 3 months. The primary objective of this study was to compare the percentage of patients achieving reduction in the severity of hemoptysis assessed on visual analogue scale (VAS) in intervention and control arm at 3 months. RESULTS: This study included 60 patients (female = 47) with mean (SD) age of 40.6 (13.2) years who were randomized to receive either bronchoscopic instillation of voriconazole (n = 30) or MT alone (n = 30). At 3-month follow-up, the primary objective was achieved in 26/30 (86.7%) patients in intervention group as compared to 11/30 (36.7%) in the control group (p value <0.0001). The VAS score at 3 months was significantly lower in voriconazole group 13.9 (9.3) mm as compared to MT alone group 22.3 (11.5) mm, p value of 0.003. Bronchoscopic instillation of voriconazole was also associated with reduction in cough severity and size of the aspergilloma; however, there was no benefit of this therapy in terms of requirement of hospitalization and BAE. CONCLUSIONS: Our study shows that for nonoperable aspergilloma, bronchoscopic instillation of voriconazole is associated with reduction in the severity of hemoptysis. This therapy should be evaluated in large multi-center trials.

Role of computed tomography angiography in the evaluation of haemoptysis in children: Decoding the abnormal vessels.

Background & objectives: Haemoptysis in children is potentially life-threatening. In most cases, the bleeding arises from the systemic circulation, and in 5-10 per cent of cases, it arises from the pulmonary circulation. The role of computed tomography angiography (CTA) in this setting is important. This study was undertaken (i) to study the role of single-phase split-bolus dual energy contrast-enhanced multidetector row CTA (DECTA) in the evaluation of haemoptysis in children; (ii) to analyze the patterns of abnormal vascular supply in the various aetiologies encountered. Methods: A retrospective study of 86 patients who underwent split bolus DECTA for the evaluation of haemoptysis was performed. Final diagnoses were categorized as normal computed tomography, active tuberculosis (TB), post-infectious sequelae, non-TB active infection, cystic fibrosis (CF), non-CF bronchiectasis, congenital heart disease (CHD), interstitial lung disease, vasculitis, pulmonary thromboembolism and idiopathic pulmonary haemosiderosis. Abnormal bronchial arteries (BAs) and non-bronchial systemic collateral arteries (NBSCs) were assessed for number and site and their correlation with underlying aetiologies. Results: A total of 86 patients (45 males, age from 0.3 to 18 yr, mean 13.88 yr) were included in the study; among these only two patients were less than five years of age. The most common cause of haemoptysis was active infection (n=30), followed by bronchiectasis (n=18), post-infectious sequelae (n=17) and CHD (n=7). One hundred and sixty five abnormal arteries were identified (108 BA and 57 NBSC), and were more marked in bronchiectasis group. Interpretation & conclusions: Active infections and bronchiectasis are the most common causes of haemoptysis in children. While post-infectious sequelae are less common, in patients with haemoptysis, the presence of any abnormal arteries correlates with a more frequent diagnosis of bronchiectasis. NBSCs are more common in post-infectious sequelae and CHD.

Chest-Wall Collateral Embolization to Reduce Surgical Blood Loss in Peripheral Aspergillomas.

OBJECTIVES: The objective of this study was to present the procedural details and digital subtraction angiography (DSA) findings of perioperative chest-wall collateral embolization (PCCE) and compare intraoperative blood loss in patients of pulmonary aspergilloma (PA) undergoing lung resection with and without PCCE. MATERIALS AND METHODS: Since November 2017, we have performed PCCE in 17 patients (14 males, three females, age 34.41 ± 12.85 years) before surgery for PA (embolization group). Retrospective evaluation of these patients was done, DSA findings were noted, and perioperative parameters (surgical approach, extent of resection, operative time, blood loss, blood transfusion, morbidity grade, and length of post-operative stay) were compared with a comparative cohort of 24 patients of PA (21 males, three females, mean age 36.13 ± 12.58 years) who underwent thoracic surgery without PCCE (May 2013-November 2017) (control group) using the Mann-Whitney U test. RESULTS: A total of 55 arteries were embolized in 17 patients (mean 3.23 arteries per patient). Technical success could be achieved in all patients without any procedure-related complications. The most common arteries embolized were posterior intercostal arteries (29) followed by costocervical trunk (10), superior thoracic (8), lateral thoracic (5), and internal thoracic arteries (3). The mean blood loss was significantly lower in the embolization group compared with the control group (676.47 vs. 1,264.58 mL, p = 0.015). Within the embolization group, patients who underwent video-assisted thoracoscopic surgery had even lower blood loss compared with open surgery cases (466 vs. 887.50 mL, p-value = 0.046). CONCLUSION: PCCE is a simple and safe procedure, useful in reducing intra-operative blood loss in patients undergoing surgery for peripherally located PA.

Pediatric lung ultrasonography: current perspectives.

Ultrasonography (US) is the workhorse of pediatric imaging; however, lung US is only a recently developed application. US of the lung is based predominantly on the imaging of chest wall-air-fluid interfaces. In this review, we summarize the available literature on applications of lung US in neonatal as well as pediatric care. We describe the imaging appearance of various commonly encountered pathologies including pneumonia and respiratory distress syndrome, among others, and provide illustrative images. Finally, we describe the limitations of the technique that are essential knowledge for radiologists, critical care physicians, sonographers and technologists attempting to use lung US effectively for diagnosis and management.

Diagnostic dilemma in an infant with stridor: ultrasound to the rescue!

Stridor is one of the most important signs of partial or complete upper airway obstruction. Subglottic hemangioma (SGH) is a well-recognized however infrequent cause of infantile stridor. It is a potentially life-threatening condition. Thus, early diagnosis and management are crucial. Diagnostic evaluation includes ultrasound, cross-sectional imaging such as contrast-enhanced CT/MRI, and tracheobronchoscopy. Ultrasound (US), although not a widely used modality for the diagnosis, provides good assessment of its presence, extent, and degree of subglottic airway narrowing. Moreover, color Doppler helps to establish the vascular nature of the lesion. There are many advantages of US over tracheobronchoscopy and CT in an emergency setting which include its easy availability, non-invasive nature, and can be done quickly as a bedside procedure, enabling early initiation of treatment. However, there are some disadvantages as well, which include limited field of view and operator dependency. Also, extension into the thoracic cavity and more deeply located soft tissue locations can be missed. We present a case of subglottic hemangioma in which US solved the diagnostic dilemma and provided a definite diagnosis when CT and tracheobronchoscopy failed to do so in a 6-month-old infant presenting with stridor to the ER.

Ingestion poisoning related lung injury- a pictorial review.

Poison ingestion is a medical emergency requiring immediate care in the emergency department. Respiratory symptoms with ingested poisons can occur due to aspiration, cardiopulmonary effects, or direct lung toxicity due to injury of the alveolar epithelium. Chest imaging (chest radiographs/CT) is usually performed in the emergency setting to evaluate such symptoms. It is often impossible to elicit the nature of the poison ingested by the patients due to their unconscious state. Identification of the culprit poison can expedite the patient's management towards a specific antidote or help understand the underlying mechanism causing the pulmonary symptoms. The imaging manifestations depend on the underlying mechanisms, varying for each ingested poison, forming an imaging signature which has not been adequately discussed in existing literature. Poisons like paraquat and organophosphate are important to differentiate as indiscriminate use of oxygen therapy in the former can exacerbate the lung injury caused by redox cycling. In this pictorial assay, we present the chest imaging spectrum of commonly ingested poisons, and further suggest algorithmic approach towards identification of common poisons based on their chest imaging.

Artificial Intelligence-assisted chest X-ray assessment scheme for COVID-19.

OBJECTIVES: To study whether a trained convolutional neural network (CNN) can be of assistance to radiologists in differentiating Coronavirus disease (COVID)-positive from COVID-negative patients using chest X-ray (CXR) through an ambispective clinical study. To identify subgroups of patients where artificial intelligence (AI) can be of particular value and analyse what imaging features may have contributed to the performance of AI by means of visualisation techniques. METHODS: CXR of 487 patients were classified into [4] categories-normal, classical COVID, indeterminate, and non-COVID by consensus opinion of 2 radiologists. CXR which were classified as "normal" and "indeterminate" were then subjected to analysis by AI, and final categorisation provided as guided by prediction of the network. Precision and recall of the radiologist alone and radiologist assisted by AI were calculated in comparison to reverse transcriptase-polymerase chain reaction (RT-PCR) as the gold standard. Attention maps of the CNN were analysed to understand regions in the CXR important to the AI algorithm in making a prediction. RESULTS: The precision of radiologists improved from 65.9 to 81.9% and recall improved from 17.5 to 71.75 when assistance with AI was provided. AI showed 92% accuracy in classifying "normal" CXR into COVID or non-COVID. Analysis of attention maps revealed attention on the cardiac shadow in these "normal" radiographs. CONCLUSION: This study shows how deployment of an AI algorithm can complement a human expert in the determination of COVID status. Analysis of the detected features suggests possible subtle cardiac changes, laying ground for further investigative studies into possible cardiac changes. KEY POINTS: • Through an ambispective clinical study, we show how assistance with an AI algorithm can improve recall (sensitivity) and precision (positive predictive value) of radiologists in assessing CXR for possible COVID in comparison to RT-PCR. • We show that AI achieves the best results in images classified as "normal" by radiologists. We conjecture that possible subtle cardiac in the CXR, imperceptible to the human eye, may have contributed to this prediction. • The reported results may pave the way for a human computer collaboration whereby the expert with some help from the AI algorithm achieves higher accuracy in predicting COVID status on CXR than previously thought possible when considering either alone.

Computed tomography chest in COVID-19: When & why?

Computed tomography (CT) of the chest plays an important role in the diagnosis and management of coronavirus disease 2019 (COVID-19), but it should not be used indiscriminately. This review provides indications of CT chest in COVID-19 suspect, positive and recovered patients based on the current scientific evidence and our personal experience. CT chest is not indicated as a routine screening modality due to its poor sensitivity and specificity. However, it is useful in a small subset of COVID-19 suspects who test negative on reverse transcription-polymerase chain reaction (RT-PCR) with normal/indeterminate chest X-ray (CXR) but have moderate-to-severe respiratory symptoms and high index of clinical suspicion. CT chest is not indicated in every RT-PCR-positive patient and should be done only in specific clinical scenarios, where it is expected to significantly contribute in the clinical management such as COVID-19 patients showing unexplained clinical deterioration and/or where other concurrent lung pathology or pulmonary thromboembolism needs exclusion. Serial CXR and point-of-care ultrasound are usually sufficient to evaluate the progression of COVID-19 pneumonia. CT chest is also indicated in COVID-19-positive patients with associated co-morbidities (age >65 yr, diabetes, hypertension, obesity, cardiovascular disease, chronic respiratory disease, immune-compromise, etc.) who, despite having mild symptoms and normal/indeterminate CXR, record oxygen saturation of <93 per cent at rest while breathing room air or de-saturate on six-minute walk test. Finally, CT chest plays a crucial role to rule out lung fibrosis in patients recovered from COVID-19 infection who present with hypoxia/impaired lung function on follow up. In conclusion, though CT chest is an indispensable diagnostic tool in COVID-19, it should be used judiciously and only when specifically indicated.

Sinonasal IgG4-related disease: a rare and emerging entity broadening the differential diagnosis in the sinonasal universe.

BACKGROUND: IgG4-related disease (IgG4-RD) is a multi-organ immune-mediated disorder characterized by fibroinflammatory mass-forming lesions, mimicking malignancy or infection. While well-documented in salivary glands, orbit and thyroid in the head and neck, sinonasal IgG4-RD is rare. METHODS: Cases of sinonasal IgG4-RD were retrieved, and clinicopathological features reviewed. RESULTS: Seven cases of sinonasal IgG4-RD were identified over a 2-year period, including three males and four females, with an age range of 13-48 years (median: 32 years). Patients presented with cheek swelling, pain and visual disturbances. Serum IgG4 levels were mildly elevated. Storiform fibrosis, obliterative phlebitis and plasma cell infiltration were seen in varying proportions. Destruction of bone and subepithelial mucoserous glands was present. ALK-1 negativity distinguished from inflammatory myofibroblastic tumor. CONCLUSION: Sinonasal IgG4-RD expands the growing spectrum of IgG4-RD. A high degree of suspicion is required to include IgG4-RD in differential diagnosis of sinonasal masses, and perform detailed histological and immunohistochemical workup for accurate diagnosis.

Revisiting rhino-orbito-cerebral acute invasive fungal sinusitis in the era of COVID-19: pictorial review.

COVID-19 patients have been found to have an increased incidence of superadded fungal infections because of multiple factors such as impaired cell-mediated immunity, immunosuppressive therapy, and coexistent diabetes mellitus. Recently, there has been a significant rise in the COVID-19-associated mucormycosis and aspergillosis cases involving the sinonasal cavity and the lungs. Rhino-orbito-cerebral acute invasive fungal rhinosinusitis (AIFR) is a potentially life-threatening, invasive fungal infection. Early diagnosis followed by prompt medical management and surgical intervention is crucial for patient survival. The role of cross-sectional imaging (CT/MRI) is not only to suggest a diagnosis of invasive fungal sinusitis but also to delineate the complete extent of disease. Mapping the extent of orbital and intracranial disease has prognostic as well as management implications, as involvement of these sites marks a worse prognosis. A stepwise approach to evaluation of imaging of AIFR along with a pictorial depiction of the key imaging findings is presented.

Does Repositioning of Temporomandibular Joint Disc With Bone Anchors Provide Better Clinical Outcomes Than Conventional Disc Plication Procedures for Anterior Disc Displacements Without Reduction in Patients Refractory to Nonsurgical Treatments?

PURPOSE: Although open temporomandibular joint arthroplasty with discopexy is a common treatment for patients with anterior disc displacements without reduction (ADDWo) unresponsive to medical management, there are no studies comparing disc repositioning with bone anchors and conventional discopexy procedure. The purpose of the study was to compare the efficacy between disc repositioning with bone anchors and the conventional discopexy procedure for ADDWo of temporomandibular joint refractory to medical management. PATIENTS AND METHODS: A randomized controlled trial was conducted in patients with ADDWo. The primary objective was to compare the improvement in mouth opening (primary outcome variable) between the 2 treatment (primary predictor variable) groups-disc repositioning with bone anchors versus conventional disc plication. Secondary outcome variables were pain measured by visual analog scale, lateral excursions, and position of the disc evaluated by magnetic resonance imaging (MRI). Other variables of interest were age, gender, and duration of symptoms. The parameters were evaluated at preoperative, postoperative day 1, and 1-, 6-, and 12-month postoperative period. Categorical variables were compared with χ2 test and continuous variables with analysis of variance and adjusted for multiple comparisons with Bonferroni test. RESULTS: The study sample comprised 14 patients (7 in each group) with MRI-proven ADDWo. Statistically significant differences were found in the improvement of mouth opening between the 2 groups, showing better improvement with bone anchors (14.42 ± 5.96 vs 7.57 ± 7.25 mm; P < .05). The reduction in visual analog scale also showed statistically significant difference with better pain reduction achieved with bone anchor (4.57 ± 1.61 vs 3.28 ± 0.75; P < .05). There was no statistically significant difference in lateral excursions and postoperative position of the disc evaluated by MRI between the groups at the 12-month follow-up period. CONCLUSIONS: Disc repositioning with bone anchors provides better clinical outcomes in terms of maximal mouth opening and pain scores compared with conventional disc plication.
