Suprafoveal condylar arthroplasty in unilateral disc displacement without reduction - A retrospective study.

The aim of this study was to evaluate the efficacy of suprafoveal condylar arthroplasty (SFCA) in the management of patients with unilateral temporomandibular joint (TMJ) disc displacement without reduction (DDWoR). A retrospective study comprising patients who underwent unilateral SFCA for clinically and radiologically confirmed unilateral DDWoR from 2008 to 2020 was conducted. Patients older than 18 years at the time of diagnosis with a minimum of 6 months of unsuccessful non-surgical and minimally invasive management (including diet and life style modification, physiotherapy, appliance therapy, pharmacotherapy, arthrocentesis and arthroscopic lysis and lavage) before undergoing surgery with a minimum of 1 year follow-up post-surgery were included in the study. Patients with other articular and extra-articular causes of restricted mouth opening, prior history of mandibular surgery and/or trauma, growth abnormalities, systemic, metabolic, infective, neoplastic conditions affecting TMJ, including gross occlusal disharmony, untreated existing para-functional habits and bilateral DDWoR, were excluded from the study. Patients were assessed in terms pain on a visual analog scale (VAS), interincisal mouth opening (MO) and subjective assessment of mandibular range of movements including deviation of mouth opening, protrusion and ability for contralateral laterotrusion. 23 patients (10 males and 13 female) were included in the study, with a mean age of 35.09 years and mean follow up period of 37.7 months (range = 12-58; SD = 15.3). The mean pain scores on the VAS reduced from 6.35 preoperatively to 1.13 postoperatively and were found to be statistically significant (p < 0.0001). The improvement of the mean pre-operative mouth opening of 21.83 mm to a mean post-operative mouth opening of 42.09 mm was also found to be statistically significant (p < 0.0001). The subjective improvement in protrusive (p = 0.0003), laterotrusive (p = 0.0005) and opening movements (p = 0.0001) after 1 year were also found to be statistically significant. No patient developed any significant changes in occlusion post-operatively. Four of 23 (17.3%) patients developed transient neuromotor deficit of the temporal branch of the facial nerve. Within the limitations of the study, it seems that SFCA (without addressing the disc) might be an alternative to less invasive treatment approaches, if the latter turned out not to be successful.

Direct, indirect, post-infection damages induced by coronavirus in the human body: an overview.

Background: Severe acute respiratory syndrome Coronavirus-2 invades the cells via ACE2 receptor and damages multiple organs of the human body. Understanding the pathological manifestation is mandatory to endure the rising post-infection sequel reported in patients with or without comorbidities. Materials and methods: Our descriptive review emphasises the direct, indirect and post-infection damages due to COVID-19. We have performed an electronic database search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines with selective inclusion and exclusion criteria. Results: The included studies substantiated the extensive damages in the multiple organs due to direct and indirect consequences of COVID-19. After an apparent recovery, the prolonged presentation of the symptoms manifests as post-COVID that can be related with persisting viral antigens and dysregulated immune response. Conclusion: A few of the symptoms of respiratory, cardiovascular, and neuropsychiatric systems that persist or reappear as post-COVID manifestations. Vaccination and preventive programs will effectively reduce the prevalence but, the post-COVID, a multisystem manifestation, will be a significant tribulation to the medical profession. However, the issue can be managed by implementing public health programs, rehabilitation services, and telemedicine virtual supports to raise awareness and reduce panic.

Post-dental extraction bleeding: Emphasis on the diagnosis of rare coagulation disorders.

Disorders of the fibrin stabilizing and fibrinolytic pathway should be considered in patients with excessive postsurgical bleeding with normal screening tests of hemostasis. History, clinical assessment of the timing and severity of bleeding along with utilization of advanced tests such as global hemostasis assays and appropriate coagulation factor assays (especially FXIII) will aid in the diagnosis.

Use of the greater palatine pedicled flap for the surgical management of trismus in oral submucous fibrosis.

The aim of this paper was to clinically evaluate the efficacy of the greater palatine pedicled flap (GPPF) for the correction of trismus in oral submucous fibrosis (OSMF). This retrospective study was designed from the patients diagnosed with OSMF who underwent transection of fibrous bands and coverage of the defect in the retromolar trigone (RMT) region using GPPF from 2008-2019. Cases were analysed for preoperative (MOpre-op), and postoperative mouth opening (MOpost-op), secondary healing of the palate, and complications of the procedure. A total of 29 diagnosed cases of OSMF were divided into two groups: group I/stage III (n=13) and group II/stage IV (n=16). The mean (SD) follow up was 29.6 (2.92) months for Group I and 32.4 (3.54) months for Group II. Increase in MOpost-op in group I from 20.0 to 32.92 mm (p=0.0001) and in group II from 6.81 to 26.31 (p=0.0001) was statistically significant. The mean difference of 6.57 mm in MOpre-op and MOpost-op among the groups was also statistically significant (p=0.0001). The mean (SD) duration for secondary healing of the palate was 5 (1) week(s) and flap necrosis was encountered in two cases of group II/stage IV OSMF. We conclude that GPPF is reliable for the treatment of trismus in advanced stages of OSMF.

Degloving Approach for the Management of Extensive Mandibular Osteomyelitis.

ABSTRACT: Extensive osteomyelitis of the mandible is usually managed using elaborate procedures including resection and reconstruction of the affected part of the mandible. This brief clinical report, the authors present a case of 75-year old male with extensive osteomyelitis of the mandible, incidentally diagnosed with anemia of chronic disease and Type I diabetes mellitus and managed using an intraoral degloving approach exclusively. This has proved to be a procedure ensuring better blood supply, decreased morbidity, precluding an elaborate reconstruction procedure and an overall reduction in cost. The advantages, scientific basis, rationale and pitfalls have been discussed briefly.

Sarcoidosis Mimicking Chronic Sialadenitis of Parotid Gland.

ABSTRACT: Non-specific Chronic sialadenitis of the Parotid gland is an inflammatory disorder that leads to several anatomical and functional changes within the glandular structure. The exact etiopathogenesis of this disorder is unknown due to its relatively rare occurrence. Primary sarcoidosis of the Parotid gland masquerading the peripheral changes of Chronic sialadenitis has never been reported in literature. We report such a case of Primary Sarcoidosis of the Parotid gland presenting with non-specific chronic sialadenitis along with ipsilateral non-reducing disc displacement of the Temporomandibular joint along with its management.

Complications of Diagnostic TMJ Arthroscopy: An Institutional Study.

INTRODUCTION: The prevalence of using arthroscopy for the diagnosis of the TMJ disorders is increasing due to its superiority to conventional methods of imaging. Although considered to be safe, complications do occur. PATIENTS AND METHOD: A single operator single-institution retrospective study consisting of 50 patients taken up for diagnostic arthroscopy was analysed for complications. RESULTS: Lacerations of external acoustic meatus was found in 03 patients (6%); immediate partial hearing loss was seen in 01 patient (2%); transient facial nerve palsy was found in 05 patients (10%); sensory disturbances over the distribution of auriculotemporal nerve was evident in 01 patient (2%); haemorrhage as visualised by excessive bleeding through trocar skin puncture wound was seen in 05 patients (5%). Post-operative pain more than the pre-operative pain on assessment by visual analogue scale was noted in 05 patients (10%) on the immediate post-operative day. Reduction in spontaneous mouth opening was noted in 15 patients (30%). CONCLUSION: Though the complication rate was found to be higher than most of the other studies, they were minor which resolved without any intervention. The cases with complications were clustered at the beginning of the series which suggests the steep learning curve and the importance of surgeons' experience and skill involved in this procedure.
