Optimal Depth of Penetration to Access the Superior Joint Space in Temporomandibular Joint Arthroscopy: A Single Institutional Retrospective Study.

Aim: To identify the optimal depth of penetration required to access the superior joint space (SJS) for arthroscopic procedures of the temporomandibular joint (TMJ) among the study population. Materials and Methods: The study included all patients with internal derangement (ID) of the TMJ, managed by TMJ arthroscopy in our institution. The study was conducted with data retrieved from the hospital records over five years (January 2018-April 2022). Demographic factors and depth of penetration (mms) were the variables included in our study. For all the statistical interpretations, p < 0.05 was considered statistically significant. Results: The study included 66 patients (males, n = 25; females, n = 41) who underwent arthroscopic procedures of the TMJ (right = 29, left = 37). The mean duration between the development of symptoms and the point of intervention (TMJ arthroscopy) in our study was 3.94 months. The mean depth of penetration of the arthroscope as measured from the skin to the point of entry into the SJS was 20.60 ± 1.85 mms in males and 19.56 ± 1.38 mms in females (p value < 0.05). Variables such as age, duration of symptoms, side involved and stage of ID did not have any influence on the optimal depth of penetration required to access the joint space among our study population. Conclusion: The optimal depth of penetration (mean) required to access the SJS was less than 25 mms in our study population.

Comparison of Intralesional Placentrex Versus Hyaluronidase and Dexamethasone Injection in the Symptomatic Management of Stage II Oral Submucous Fibrosis - a Prospective Study.

AIM: The present study aimed to compare the effectiveness of intralesional placentrex versus hyaluronidase + dexamethasone injection in the symptomatic management of stage II OSMF. MATERIALS AND METHODS: This was a non-randomized prospective study conducted over a period of 14 months at a tertiary referral center. Patients with clinical stage II OSMF were randomly grouped into A(n = 18) and B(n = 17). These patients were treated with weekly intralesional injection of placentrex and hyaluronidase + dexamethasone respectively, over a period of six weeks. Variables such as mouth opening, burning sensation and colour of mucosa were evaluated at baseline(T0), second week(T1), fourth week(T3), sixth week(T4) of follow up. A p-value < 0.05 was considered statistically significant. RESULTS: A total of 15 patients completed the study in each group with regular follow up. The mean improvement in mouth opening was 4.3 ± 0.57 mms in group A(p-value < 0.001) and 7.2 ± 0.76 mms in group B(p-value < 0.001) which were significant at the end of six weeks. Mean change in burning sensation at the end of six weeks in group A was 1.2 ± 0.73(p-value < 0.001), and 3.6 ± 0.63(p-value < 0.001) in group B. Mean change in colour of mucosa at the end of six weeks was 1.4 in group A(p-value > 0.05) and 2 in group B(p-value > 0.05). On comparison between both groups, patients in group B exhibited better mouth opening and reduction of burning sensation than patients in group A(p-value < 0.001). CONCLUSION: Both intralesional placentrex and hyaluronidase + dexamethasone injection are effective in alleviating the symptoms of stage II OSMF. However, hyaluronidase + dexamethasone injection showed slightly better improvement in mouth opening and burning sensation after six weeks.

Causes of late-presenting developmental dislocation of the hip beyond 12 months of age: A pilot study.

Background & objectives: Developmental dysplasia of the hip (DDH), when detected early, can usually be managed effectively by simple methods. A delayed diagnosis often makes it a complex condition to treat. Late presentation of DDH is fairly common in developing countries, and there is scarcity of literature regarding the epidemiology and reason for late presentation. Through this study, we attempted to identify the reasons for late presentation of DDH in children more than 12 months of age. Methods: Fifty four children with typical DDH and frank dislocation of hip in whom treatment was delayed for 12 months or more were included. Parents were interviewed with a pre-structured questionnaire and data were collected for analysis with Microsoft Excel 2016 and SPSS version 26. Results: Diagnostic delay was the most common reason for late presentation and was observed in 52 children (96.2%). The mean age at diagnosis was 24.7 months. The mean age at treatment was 37.3 months with a mean delay of 12.5 months from diagnosis and 22.1 months from initial suspicion. Physician-related factors contributed 55.3 per cent, while family and social issues accounted for 44.7 per cent of overall reasons for diagnostic and treatment delays. Interpretation & conclusions: Late presentation of DDH in walking age is common. Physician- and family-related factors accounted for most of these cases. Failure or inadequate hip screening at birth by the attending physician is a common reason for late diagnosis. The family members were unaware about the disorder and developed suspicion once child started walking with an abnormal gait.

Predictors of atrial fibrillation post coronary artery bypass graft surgery: new scoring system.

BACKGROUND: Atrial fibrillation (AF) following coronary artery bypass graft surgery (CABG) is common and results in significant increases in hospital stay and financial encumbrance. OBJECTIVE: Determine and use the predictors of postoperative AF (POAF) following CABG to develop a new predictive screening tool. METHOD: A retrospective case-control study evaluated 388 patients (98 developed POAF and 290 remained in sinus rhythm) who undertook CABG surgery at Townsville University Hospital between 2016 and 2017. The demographic profile, risk factors for AF including hypertension, age≥75 years, transient ischaemic attack or stroke, chronic obstructive pulmonary disease (HATCH) score, electrocardiography features and perioperative factors were determined. RESULTS: Patients who developed POAF were significantly older. On univariate analysis HATCH score, aortic regurgitation, increased p-wave duration and amplitude in lead II and terminal p-wave amplitude in lead V1 were associated with POAF; as were increased cardiopulmonary bypass time (103.5±33.9 vs 90.6±26.4 min, p=0.001) and increased cross clamp time. On multivariate analysis age (p=0.038), p-wave duration ≥100 ms (p=0.005), HATCH score (p=0.049) and CBP Time ≥100 min (p=0.001) were associated with POAF. Receiver operating characteristic curve demonstrated that with a cut-off of ≥2 for HATCH score, POAF could be predicted with a sensitivity of 72.8% and a specificity of 34.7%. Adding p-wave duration in lead II >100 ms and cardiopulmonary bypass time >100 min to the HATCH score increased the sensitivity to 83.7% with a specificity of 33.1%. This was termed the HATCH-PC score. CONCLUSION: Patients with HATCH scores ≥2, and those with p-wave duration >100 ms, or cardiopulmonary bypass time >100 min were at greater risk of developing POAF following CABG.

Role of iodoform in jaw lesions: a systematic review.

Iodoform formulations are used as packing material following the surgical removal of jaw lesions. The purpose of this review was to explore the evidence and efficacy of iodoform-based dressings. We have systematically reviewed published articles according to the PRISMA statement. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library database for articles mentioning the use of iodoform as dressing material for jaw lesions from January 2000 to March 2022. Finally, 92 studies were included. A total of 386 patients whose ages ranged from five months to 86 years (male n = 180, female n = 117). Different formulations of iodoform used were BIPP (n = 67), Whitehead's varnish (n = 17), iodoform (n = 7) and, iodine (n = 1) for its antiseptic properties. An iodoform impregnated gauze pack was changed once a week, most commonly, for a stipulated duration, until complete healing of the cavity. In the present review, iodoform was used, most commonly, in pathological cavities following surgical treatment of ameloblastoma and odontogenic keratocyst. Toxicity was reported in two studies. Based on the current review, iodoform is relatively safe and can be used in the management of extensive jaw lesions in which secondary healing is expected. Prospective and randomised control trials are recommended to assess the efficacy of various formulations and to delineate the timeframe for patient compliance.

Infralingular Versus Supralingular Medial Osteotomy in Sagittal Split Osteotomy of the Mandible: A Randomized Control Study.

PURPOSE: A recently proposed modification of the sagittal split osteotomy (SSO) of the mandible places the horizontal medial cut 'low and short' of the lingula. The purpose of the study was to answer the following clinical question: Among patients undergoing mandibular setback procedures (≤ 8 mm) via SSO, does the placement of the medial horizontal osteotomy below the lingula (infralingular), when compared to placement above the lingula (supralingular), results in different neurosensory, bite force, and range of motion outcomes? MATERIALS AND METHODS: This was a single-center, double-blind, parallel-group study among patients undergoing mandibular setback by SSO (≤ 8 mm), between January 2021 and September 2022. Patients were randomly allocated in a ratio of 1:1 to the supralingular (control) and the infralingular (study) group. Primary outcome variables included neurosensory disturbance of the inferior alveolar nerve based on clinical neurosensory testing and severity graded using Zuniga and Essick's protocol, bite force, and maximum mouth opening evaluated postoperatively during the first week (T1), first month (T2), and third month (T3) of follow-up. Secondary outcome measures included the incidence of a bad split and distal segment interferences intraoperatively. Association between the variables was assessed using Pearson chi-squared test or Fisher's exact test based on the expected observations. A P value of ≤.05 was considered statistically significant. RESULTS: A total of 29 patients (58 osteotomies) were included in the study. Group 1 consisted of 15 patients (9 females and 6 males) with a mean age of 26.4 years. Group 2 consisted of 14 patients (8 females and 6 males) with a mean age of 25.9 years. Patients with severe neurosensory disturbance of the inferior alveolar nerve were more common in group 2 (n = 15, 53.6%) than group 1 (n = 4, 13.3%) at T1 (P value = .0001) and insignificant between the two groups at T2 (P value = .63) and T3 (P value = .99). Comparison of maximum mouth opening between the two groups at T1 (P value = .535), T2 (P value = .934), and T3 (P value = .703) and bite force at T1 (P = .324), T2 (P = .113), and T3 (P = .811) was not significant. CONCLUSION: Both SSO techniques have similar clinical outcomes among patients having mandibular setbacks (≤ 8 mm) for the variables studied.

Extracranial schwannoma of the maxillary nerve misdiagnosed as trigeminal neuralgia in an elderly patient with schizophrenia - A diagnostic dilemma.

The present paper discusses the diagnostic challenges we faced in a 60-year-old woman with a history of schizophrenia, presenting with left unilateral facial pain for the past three months. Based on the elaborate clinical examination and diagnostic nerve blocks, the patient was diagnosed with trigeminal neuralgia (TN) and non-surgical therapy commenced. Further investigations with magnetic resonance imaging (MRI) and ultrasound-guided fine needle aspiration cytology (FNAC) revealed the presence of an extracranial schwannoma involving a branch of the maxillary nerve. The patient was symptomatically relieved after surgical excision of the benign tumor under general anesthesia. Hence, we emphasize the need for special care and attention in psychiatric patients presenting with orofacial pain.

Complications of arthroscopic lysis and lavage in internal derangement of the temporomandibular joint - A single institutional experience with review of literature.

PURPOSE: To evaluate the complications of arthroscopic lysis and lavage with joint sweep (ALL) procedure in the management of disc derangement of the temporomandibular joint. METHODS: Patients with internal derangement of the TMJ who were treated by ALL in a tertiary institution from July 2018 to December 2021 were studied retrospectively. RESULTS: The study included 39 patients (males, n = 14; females, n = 25) and 50 joints. The complications observed in the study were classified into intra and post operative complications. Post operative complications such as pain (16%), swelling (6%), reduced mouth opening (22%) and neurological complications were the most commonly observed ones. Rare complications such as ipsilateral palatal swelling (6%), parapharyngeal swelling (4%), and post operative malocclusion (2%) were also observed. CONCLUSION: Although the complications of ALL are entirely unavoidable, their incidence can be reduced by strict adherence to standard techniques. Three-dimensional awareness and orientation of the dangerous angles and depth around the TMJ region is mandatory to reduce the complications.

Palatal Flap: An Optimistic Salvagable Option to Negate the Maxillectomy Defects in COVID Related Rhino-Orbito-Cerebral Mucormycosis.

We present three cases diagnosed with COVID-19 associated Rhino-orbito-cerebral mucormycosis, managed by aggressive debridement and resection of the involved maxilla, followed by primary closure with preserved palatal flap, thus trying to establish its versatility for the closure of the maxillectomy defects.

Clinico-Radiological and Functional Outcome of Difficult Talipes Equinovarus Deformity Corrected With an Ilizarov Fixator.

Relapsed, resistant, and untreated congenital talipes equinovarus poses significant challenges in view of functional outcome following conventional serial casting and soft tissue release procedures. The Ilizarov ring fixator here offers significant possibilities as an extended conservative treatment modality. The aim of the present study was to critically evaluate effectiveness of the Ilizarov ring fixator with regard to radiological, clinical, and functional outcomes, in the difficult clubfeet. The study was carried out on patients presenting with relapsed, resistant, or untreated congenital talipes equinovarus deformity, who underwent deformity correction using the Ilizarov ring fixator application. All patients were reviewed at 6 monthly intervals for over 3 years following fixator removal with an objective clinical, radiological, and functional assessment. Twenty-three patients with 30 clubfeet were enrolled in our study. The mean age was 8.3 ± 3.6 (range 4-17) years. The postoperative clinical, radiological, and functional scores showed statistically significant improvement among all patients when compared with the preoperative data. All 30 feet developed varying complications during treatment with pin track infections being the most common. However, they were managed while continuing the distraction correction process. The Ilizarov ring fixator is an effective and reliable solution for difficult and challenging clubfeet. However, one must be aware of a strict adherence to a bracing protocol to avoid recurrence of deformities. A regular periodical functional and clinical follow up must be ensured among these children for a favorable outcome.

Retrieval of Migrated Embedded Sewing Machine Needle from the Tongue.

Foreign body in the oral cavity can be encountered by Head and Neck Surgeons in their clinical practice. Here, we report a rare case of an embedded sewing machine needle in the posterior tongue that migrated by tongue movements, and was retrieved successfully by surgical intervention.

Post-traumatic Actinomycotic Oro-antral Fistula Closure with Three-dimensional Stereolithographic Modeling and Patient-Specific Titanium Implant.

We report an interesting case of a post-traumatic actinomycotic oro-antral fistula of the left posterior maxilla, that was not salvageable via local flaps due to the size of the defect and was managed with the patient-specific titanium implant, fabricated by three-dimensional stereolithographic model planning followed by primary closure.

Current controversies in management of fracture neck femur in children: A review.

Paediatric femur neck fracture is an uncommon injury and is known for high rate of complications. This in turn, can have significant impact on development of hip and overall function of the child. Controversy prevails in many areas of management and it still remains a difficult injury to manage. Through this paper, an attempt has been made to summarize the current concepts in management and suggest current recommendations regarding the controversies so that these injuries can be managed judiciously. A systematic review was done as per PRISMA guidelines using pre-defined inclusion and exclusion criteria. 18 studies with better scientific evidence after quality assessment were included in the systematic review. Current trends and Controversial issues in management were then identified and discussed. It was observed that existing literature is inconclusive regarding several aspects of management of this injury with no clear guideline available. However, certain recommendations useful for decision making could be made. These injuries should be managed aggressively with operative fixation at the earliest and one should not hesitate to open reduce if acceptable alignment is not obtained after one or two gentle closed manipulations. Choice of implant and their configuration in neck can vary depending on age and weight of patient, type of injury and surgeon's preference. Initial fracture displacement could be considered to be most predictive for development of osteonecrosis of the femoral head, whereas, role of surgical decompression, type of fixation and timing of surgery is still debatable. Functional outcome is primarily affected by osteonecrosis of the femoral head, nonunion and severe coxa vara, whereas mild coxa vara, shortening, and premature closure of physis when considered alone, don't have significant influence on functional outcome in short term. Treatment of fracture neck femur in children is still controversial in many aspects and needs further research. It should be understood that complications can occur regardless of the method of treatment and might reveal their full impact many years after injury. Hence, a guarded prognosis should be explained to the parents and care-givers at the time of injury.

Quantitative Prediction of Change in Chin Position in Le Fort I Impaction.

BACKGROUND: Vertical maxillary excess, a dentofacial deformity present in a large proportion of population impute an increased lower facial height due to increased maxillary height. This results in a clockwise rotation in the mandible, and the chin advances posteriorly and inferiorly. Le Fort I superior repositioning of the maxilla begets movement of pogonion point anteriorly and cranially. Cephalometric analysis helps to access change in position of chin following Le Fort I impaction. In our study, from this analysis a formula was defined to perceive the exact amount of this change in chin position along the vertical and sagittal plane as a result of autorotation. MATERIALS AND METHODS: This experimental study assessed 45 patients with vertical maxillary excess over a period of 2 years and 6 months (January 2016-May 2018) in Government Medical College Hospital, Kottayam, Kerala, India. The planned procedure was Le Fort I superior impaction for correction of vertical maxillary excess. Pre-operative cephalograph was taken initially. Post-operative cephalograph after 3 months was then compared with initial pre-operative cephalograph to assess the change in position of the pogonion and menton. RESULTS: Forty-five participants were studied. The multiple regression model was applied to predict the changes in the chin (dependent factor) according to the vertical change in the maxilla (predictive factor). For every 1 mm change in the maxilla vertically, the chin was estimated to move 0.59 vertically. For a standard deviation increase of 1 in the position of the maxilla, the chin moved superiorly by 0.744 of the standard deviation. For every 1 mm of vertical change in the maxilla, the chin could be expected to move 0.22 mm horizontally. For a standard deviation increase of 1 in the maxillary position, the chin advanced by 0.273 of the standard deviation. CONCLUSION: This study draws to a conclusive finding that the movement of maxilla in the superior direction has an effect on the repositioning of the chin in the anterior and cranial directions. This has led to a formulation that 1 mm of superior impaction of maxilla results in 0.6 mm of vertical and 0.2 mm of sagittal movement of chin. This might help to have a glance of future chin position and aid in deciding the need for mandibular surgery.

Effects of accelerated versus standard care surgery on the risk of acute kidney injury in patients with a hip fracture: a substudy protocol of the hip fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) international randomised controlled trial.

INTRODUCTION: Inflammation, dehydration, hypotension and bleeding may all contribute to the development of acute kidney injury (AKI). Accelerated surgery after a hip fracture can decrease the exposure time to such contributors and may reduce the risk of AKI. METHODS AND ANALYSIS: Hip fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) is a multicentre, international, parallel-group randomised controlled trial (RCT). Patients who suffer a hip fracture are randomly allocated to either accelerated medical assessment and surgical repair with a goal of surgery within 6 hours of diagnosis or standard care where a repair typically occurs 24 to 48 hours after diagnosis. The primary outcome of this substudy is the development of AKI within 7 days of randomisation. We anticipate at least 1998 patients will participate in this substudy. ETHICS AND DISSEMINATION: We obtained ethics approval for additional serum creatinine recordings in consecutive patients enrolled at 70 participating centres. All patients provide consent before randomisation. We anticipate reporting substudy results by 2021. TRIAL REGISTRATION NUMBER: NCT02027896; Pre-results.

Rationale and design of the HIP fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) Trial: a protocol for an international randomised controlled trial evaluating early surgery for hip fracture patients.

INTRODUCTION: Annually, millions of adults suffer hip fractures. The mortality rate post a hip fracture is 7%-10% at 30 days and 10%-20% at 90 days. Observational data suggest that early surgery can improve these outcomes in hip fracture patients. We designed a clinical trial-HIP fracture Accelerated surgical TreaTment And Care tracK (HIP ATTACK) to determine the effect of accelerated surgery compared with standard care on the 90-day risk of all-cause mortality and major perioperative complications. METHODS AND ANALYSIS: HIP ATTACK is a multicentre, international, parallel group randomised controlled trial (RCT) that will include patients ≥45 years of age and diagnosed with a hip fracture from a low-energy mechanism requiring surgery. Patients are randomised to accelerated medical assessment and surgical repair (goal within 6 h) or standard care. The co-primary outcomes are (1) all-cause mortality and (2) a composite of major perioperative complications (ie, mortality and non-fatal myocardial infarction, pulmonary embolism, pneumonia, sepsis, stroke, and life-threatening and major bleeding) at 90 days after randomisation. All patients will be followed up for a period of 1 year. We will enrol 3000 patients. ETHICS AND DISSEMINATION: All centres had ethics approval before randomising patients. Written informed consent is required for all patients before randomisation. HIP ATTACK is the first large international trial designed to examine whether accelerated surgery can improve outcomes in patients with a hip fracture. The dissemination plan includes publishing the results in a policy-influencing journal, conference presentations, engagement of influential medical organisations, and providing public awareness through multimedia resources. TRIAL REGISTRATION NUMBER: NCT02027896; Pre-results.

Comparison of clinical outcomes of treatment of dysfunction of the temporomandibular joint between conventional and ultrasound-guided arthrocentesis.

Patients with disorders of the temporomandibular joint (TMJ) who do not respond to non-operative treatment may require invasive procedures such as arthrocentesis and arthroscopy. We divided 80 patients with dysfunction of the TMJ into two groups: a control group who were treated by conventional arthrocentesis, and an experimental group who were treated by ultrasound-guided arthrocentesis. Both groups were monitored three days, one week, and one month postoperatively and the clinical outcomes compared. The experimental group had a significant reduction in the degree of pain in the immediate postoperative period (p=0.015). However, ultrasound-guided arthrocentesis showed no significant improvement in symptoms overall compared with conventional arthrocentesis. Both techniques seem to be effective in the management of dysfunction of the TMJ.
