RESUMO
BACKGROUND: Facial nerve (FN) dysfunction is a potential complication during open reduction of mandibular condylar fractures. PURPOSE: The purpose of this study was to measure and compare the postoperative FN function following transparotid (TP) and transmasseteric anterior parotid (TMAP) operative approaches in open reduction and internal fixation of condylar fractures using electromyogram. STUDY DESIGN, SETTING, SAMPLE: A randomized controlled clinical trial was designed. The study was conducted in a single tertiary-care hospital in the inpatient setting. Patients aged above 18 years with unilateral condylar fracture of the jaw or bilateral condylar fractures undergoing surgery on only 1 side were included. Patients were excluded if they had fractures of the head, bilateral condylar fractures with surgery planned on both sides, a previous history of surgery in the retromandibular area, existing lacerations to approach condyle, preoperative signs of FN weakness, or a history of parotid surgery. PREDICTOR VARIABLE: The predictor variable was the operative approach and the subjects were allocated randomly to TMAP and TP. MAIN OUTCOME VARIABLE(S): The primary outcome variable was postoperative FN function in the surgical approach employed using the House-Brackmann scale and electromyography (EMG) to record any subtle weakness in nerve function. The FN function is recorded at 3 time intervals postoperatively 1 week (T1), 1 month (T2), and 3 months (T3). The secondary outcomes studied were operating time and any other complications recorded. COVARIATES: Age, sex, fracture pattern with classification of condylar fractures into condylar neck or base fractures according to Loukata et al.4 Any associated fracture of mandible describing the anatomical location viz symphysis and parasymphysis (anterior mandible), body, contralateral condyle or greater than 1 associated fracture were recorded. Similarly, the presence or absence of any associated midface fracture was also recorded to suggest that the study participants were homogenous in all aspects. ANALYSES: Analytical statistics included χ2 test, t-test, and repeated measures ANOVA followed by post hoc test to compare EMG data (mean power and mean amplitude) between 2 operative approaches (TP vs TMAP) for facial muscles including frontalis, oculi, and buccinator at different time intervals (T0, T1, T2, T3). Patients within each group were also analyzed to check for nerve recovery occurring during the follow-up period. The level of significance was set at P < .05. RESULTS: The study sample was composed of 22 patients with a mean age of 32.82 ± 11.21 years in TMAP and 27.82 ± 8.54 years in the TP group respectively (P = .26); male predominance of 81.8 and 90.9% in TMAP and TP group respectively (P = .53) was noted. The FN deficit as assessed by the House-Brackmann scale clinically, was at 54% (T1), 36.4% (T2), and 9.1% (T3) for the TP group and 27% (T1),9% (T2), and 0% (T3) for TMAP group; however, the results were statistically insignificant (P = .31). In surface EMG evaluation, the mean power for the frontalis muscle was significantly higher in the TMAP approach at the T3 time (105.03 ± 9.7 vs 89.56 ± 10; 95% confidence interval -24.28 to -6.65 with P value = .002). TP approach was faster with a mean exposure time of 9.9 minutes. CONCLUSION AND RELEVANCE: The results show that both approaches give comparable long-term results with the TMAP group showing better frontalis muscle activity.
RESUMO
Infantile fibromatosis is characterized by proliferation of fibrous soft tissue with a potential of invading the adjacent structures but lacks the ability to metastasize, thus making it a fairly benign lesion with borderline characteristics. The pathology resembles sarcomatous growth, therefore making it difficult for the clinician to correctly diagnose. There are two variants of extra-abdominal desmoid juvenile and adult variant depending upon the age group it predominately involves. Fibromatosis is comparatively a rare tumour with unpredictable growth and varying local recurrence rates. The mass usually grows slowly, rapid growth and recurrences being mostly associated with the juvenile forms. The disease may present as single or multifocal lesion with widespread distribution, thus requiring whole body scans to identify any insidious growth elsewhere. Here, we report a case of recurrent juvenile/infantile fibromatosis in a 2-year-old child, conservatively managed without any growth disturbance and signs of recurrence.
RESUMO
The objective was to understand the prevalence of temporomandibular joint disorder among dental students. The study was conducted in Tagore Dental College, Chennai. The questionnaire study included a total of 371 students from years I to V, under the age group of 18-30, who had a history of temporomandibular joint disorders on the day of the survey. Each student was given a semi-structured study questionnaire related to assessing possible causes, assessment of habits, assessment of subjective symptoms, and evaluation of pain. It was analysed using an anamnestic scale as 0: no symptoms; I: mild symptoms; II: severe symptoms. An independent t-test was used to compare the variables. The significance level set at 0.05 (p < 0.05) showed that the prevalence of Temporomandibular disorders was insignificant in the study population due to various contributing factors.

RESUMO
PURPOSE: Distoangular impacted teeth are considered challenging to remove due to their anatomic position. Proper tooth sectioning ensures the removal with minimal bone removal. This study aimed to compare the outcomes of 2 different tooth sectioning methods. MATERIALS AND METHODS: Patients with distoangular-impacted mandibular third molar were included in this single-blinded randomized controlled trial. Patients with Class III-impacted, grossly decayed teeth and who were ASA III and above were excluded. The subjects were randomly allocated into Group-A conventional method, where tooth sectioning at the cementoenamel junction, and Group B, the modified method, where tooth sectioning removes only the distal portion of the crown. The primary predictor variable was the tooth sectioning method. The primary outcome variable was the operative time and the secondary outcomes included postoperative pain, trismus, and edema assessed on postoperative days 3 and 7. The effect of treatment on operative time was assessed using a t-test and Chi-squared test was used to compare the categorical data. RESULTS: Thirty eight patients were included in this study. With a 1:1 allocation ratio, 18 (50%) patients were included in each group. No statistically significant differences were observed in the 2 groups for gender allocation (P = .32), age (P = .34), tooth classification (P = .97), and side of extraction (P = .32). The mean operative time was 31.61 ± 14.13 minutes for group A and 22.72 ± 10.79 minutes for group B, at the 95% confidence interval had a P value of .04 (P < .05), favoring group B. Secondary outcomes of pain measured by visual analogue scale 3.83 ± 3.06 for group A and 3.88 ± 3.06 for group B (P = .95), facial edema 22.79 ± 2.08 and 22.88 ± 1.32, respectively (P = .88), and the maximal interincisal opening of 33 ± 8.59 and 31.33 ± 7.42 on day 3 (P = .54) and 36.16 ± 11.62 and 39.05 ± 6.08 on day 7 (P = .36). However, the difference in need for rescue analgesia 2.05 ± 2.15 and 0.44 ± 0.85 (P < .01) was statistically significant, suggesting the superiority of the conventional sectioning method. CONCLUSIONS: The results show that both methods of tooth sectioning yield comparably acceptable results. However, the tooth removal was faster by the modified sectioning and the need for rescue analgesia was minimal in this group, suggesting it to be a preferred technique over the conventional method.

Background: Condylar head fractures is difficult to treat because of medial displacement caused by muscle pull and limited access to visualize the proximal segment and secure them back to anatomic position. A novel technique is proposed to overcome the difficulties and ease the task of a surgeon. Purpose: The main goal in Open reduction and internal fixation is to achieve anatomical position and establish occlusion, a task possible only after securing the segment back into place. Over decades, many authors have described various techniques to ease the task yet surgeons are forced to treat cases using closed technique which adds limitation to the rehabilitation of stomatognathic system for a prolonged time. Methods and Materials: Self holding screw driver, 1.5x10mm monocortical screws and drill bit. Using any preauricular access incision, dissection is proceeded anteromedially and the medial segment is identified. A drill hole is made with 1.2 mm diameter drill with counter using periosteal retractor, monocortical screw fixed and segment secured using a self-holding driver and lateralized after increasing the joint space thus achieving the original retromandibular height. Results: The treatment outcomes are better achieved with ease to surgeon and with minimal armamentarium without any special needs per se. Conclusion: The technique proposed is novel and can help achieve desired outcomes even in hands of budding surgeon with minimal time and efforts invested.
RESUMO
Aim: To perform site-based comparative analysis for samples collected from the nasal region and oral cavity subjected to microscopic detection of fungal hyphae in KOH mount in a group of patients with rhinomaxillary mucormycosis. Methodology: Forty patients fulfilled eligibility criteria. The diagnostic outcome of detection of fungal hyphae from the KOH samples obtained was the primary endpoint of the study. Based on this, the samples were grouped into three groups viz-oral, nasal and both. The secondary outcome was to check if there was any diagnostic delay in these three groups of patients. Results: The mean number of days for delayed diagnosis for oral site involvement was 56.33 ± 37.53, for nasal involvement was 32.86 ± 19.53 and for both oral and nasal involvement was 22.00 ± 12.94. This difference was statistically significant at p = 0.03. The mean delay in diagnosis was significantly less when both oral and nasal regions are involved as compared to the only oral region involved at P = 0.01. Conclusion: To avoid the chance of delayed diagnosis or false-negative results, it is best to collect samples from both nasal tissues and the most representative site in the dentoalveolar segment depending on the extensiveness of the disease.
RESUMO
Melioidosis is a potentially fatal, life-threatening infection caused by the gram-negative saprophytic organism Burkholderia. It is a disease endemic to Southeast Asia and Northern Australia. This infection transmits through direct contact, cutaneous inoculation, inhalation, or ingestion, and patients clinically exhibit abscesses in single or multiple organs. It is clinically under-reported due to a low index of suspicion, lack of diagnostic facilities, and misdiagnosis as tuberculosis. Infections of the musculoskeletal system are exceedingly rare, and clinical presentation may vary from the involvement of femoral bone, palmar tenosynovitis, and parietal bone osteomyelitis secondary to central nervous system involvement. The rarity of the melioidosis to secondarily infect a developmental odontogenic cyst leading to focal osteomyelitis of mandible prompts the clinician toward thorough evaluation for early diagnosis and treatment.
RESUMO
Ludwig's angina is a rapidly spreading, potentially fatal infection of deep fascial spaces of the neck leading to airway oedema and death. This, in recent times when associated with COVID-19 infection, possess treatment challenges making the patient susceptible to opportunistic infections with reduced healing potential. Owing to the multifactorial aetiology in our case and addressing them at the earliest, it is important to achieve favourable outcomes. The space infection that seeded with untreated trivial dental caries progressed to necrotising fasciitis of neck with mycobacterial growth on cartridge-based nucleic acid amplification test for tuberculosis testing. The presence of Mycobacterium organisms should be speculated in patients with pulmonary signs of tuberculosis (TB) because a suppurative TB lymphadenitis of neck could also have the same presentation. The decisive moment in successful outcome was identification of mycobacteria in COVID-19 infected patient, thereby allowing to initiate the antitubercular therapy along with surgical debridement. Thus, medical management of patient with cohabiting infections is difficult task and needs appropriate addressal.

Psammomatoid Juvenile ossifying fibroma (PsJOF) is a rare benign fibro-osseous lesion characterised to grow to unusually large size very rapidly. Its usual presentation is in younger age group mostly children and predominately involving the Sino-Naso-Orbital region. Its aggressive nature gimmicks a malignant lesion but it is rather a benign lesion with a higher recurrence rate than the conventional ossifying fibroma but lacking metastatic potential. The high recurrence rate makes it essential that the lesion is not reconstructed immediately and thorough monitoring in the follow-up period. Lesion of such clinical importance needs to be diagnosed preoperatively to provide a better and radical surgical treatment option, but the variability in its presentation as seen in this case makes it even harder to diagnose. We aim to draw attention to the rare phenomena that PsJOF presents to help readers broaden their purview in diagnosis and thereby manage them accordingly.
