ABSTRACT
Background and Aims: An objective understanding of pain guides the effectiveness of various postoperative pain management strategies. The measurement of pain by the visual analogue scale (VAS) is dependent on the individual's cognitive and emotional ability. Pupillary dilatation has been successfully used to measure pain in quantitative terms. The present study was conducted to study the correlation between VAS and pupillary diameter in the evaluation of postoperative pain. Methods: This observational study was carried out on 85 patients 18-65 years of age, scheduled for lower abdominal surgical procedures under general anaesthesia. Postoperative pain assessment was done using the VAS at 6 h, 12 h, 18 h and 24 h. In addition, the pupillary diameter of both eyes was measured simultaneously. Paired t-test and analysis of variance (ANOVA) were used to compare the data, and Pearson's correlation coefficient was calculated to assess the bivariate correlation between VAS score and pupillary diameter. Results: Mean ± standard deviation (SD) of VAS scores at baseline, 6 h, 12 h, 18 h and 24 h postoperatively were 0, 4.88 ± 0.88, 3.39 ± 0.86, 2.19 ± 0.66 and 1.40 ± 0.49, respectively. Mean change was significant at all time intervals (P < 0.001). The mean ± SD change in average pupillary diameter was 0.59 ± 0.64, 0.44 ± 0.54, 0.22 ± 0.34 and 0.07 ± 0.22 mm, respectively, showing a significant change from baseline (P < 0.05). On overall evaluation, mean pupillary diameter showed a significant incremental trend with an increasing VAS score (P < 0.001). Conclusion: Change in pupillary diameter correlated well with the pain scores (VAS) and thus pupillary diameter can be chosen as an objective measurement of postoperative pain severity.
ABSTRACT
Purpose: The present study aimed to evaluate the statistical significance of comprehensive facial injury (CFI) score concerning total surgical time (ST), length of hospital stay (LHS), and head injury in maxillofacial trauma patients. Methods: This retrospective observational study included 288 patients having maxillofacial injuries with or without associated head injury. CFI score was calculated for each of them. One-way ANOVA and Kruskal-Wallis H-test were used to compare ST (minutes), LHS (days), and Glasgow Coma Scale (GCS) score among the CFI score clusters. Head injury among the CFI score clusters was compared using Fisher's exact test. The level of statistical significance was set at P < 0.05. Results: Of total 288 cases (males: 83.68%, females: 16.31%, mean age: 30 ± 15.92 years), road traffic accidents accounted for 76.0% of admissions. A definitive approach (open reduction and internal fixation) was used in 26.38% of cases. Statistically significant association of CFI score was obtained with ST and LHS in high-dependency unit (P < 0.001). Posttraumatic head injury was seen in 21.25% of cases. A significant association of CFI score with GCS score (P = 0.032) and with head injury (P = 0.019) was found. Conclusion: CFI score is a comprehensive yet simple scale to assess ST and LHS. A strong correlation established between CFI score and these variables further validate its reliability as a perfect tool for communication of the maxillofacial morbidity and in making a treatment protocol, although its predictive ability for associated head injuries needs to be studied further.
ABSTRACT
STUDY DESIGN: The Coronavirus disease-19 (COVID-19) pandemic has disrupted oral and maxillofacial (OMF) surgeons' practice globally. We implemented a cross-sectional, questionnaire-based survey among the OMF surgeons of India. OBJECTIVE: The objectives of the study were (1) gathering data among the maxillofacial surgeons in terms of their occupational exposure and access to adequate personal protective equipment (PPE) and (2) to estimate how the COVID-19 pandemic has affected the practice of OMF surgeons in India. MATERIALS AND METHODS: Complete responses of 178 OMF surgeons were included in the study. Descriptive and analytic statistics were computed. The level of statistical significance was set at P < 0.05. Binary logistic regression models were created to assess the predictors of the impact of the COVID-19. RESULTS: Out of the 178 respondents of the study, most (37.1%) were following their hospital's guidelines. Most had access to adequate PPE (89.9%), whereas 93.8% had COVID-19 testing available. One hundred and thirty-three (74.7%) surgeons were involved in teleconsultation. Ninety-two (51.7%) and 166 (93.3%) were involved in elective surgery and emergency surgeries, respectively. Median outpatient department cases and number of surgeries done per week reduced by 73.9% and 66.7% (P < 0.001), respectively. Most surgeons (86%) experienced that cost of treatment had increased during the COVID. Over 75% were afraid to get infected with COVID, whereas 44.9% were anxious to lose the income. More than 56% of the OMF surgeons reported a fall in income and 94% reported decreased productivity in academic research. Most surgeons (93.8%) believed that COVID had a positive impact on human behavior in terms of hand hygiene. CONCLUSION: The impact of COVID-19 among OMF surgeons has adversely affected clinical practice, personal lives, and academic productivity and has catalyzed an exponential increase of telemedicine. Future surveys should capture the long-term impact of COVID-19.
ABSTRACT
BACKGROUND: The oro antral fistula (OAF) is an unnatural epithelialized communication between oral cavity and maxillary sinus. It may heal spontaneously but a larger fistula requires surgical intervention. OAF causes excruciating pain, escape of fluids from nose, escape of air from mouth into nose, epistaxis, change in voice due to resonance, purulent discharge in case of chronic OAF, post nasal discharge, popping out of antral polyp into oral cavity and sinusitis. Closure of OAF is strenuous, technique sensitive and challenging. AIMS AND OBJECTIVES: To compare and evaluate the efficacy of buccal fat pad and buccal advancement pad for closure of oroantral fistula. MATERIALS AND METHODS: Twenty patients of age ranging from 24-64 years with complaint of OAF were included in this prospective, comparative analytic study. In group I, OAF was treated with a buccal advancement flap and in group II, BFP was sutured over the defect. All patients were called for follow up on 1st, 7th, 14th and 21st day post operatively. Pain, mouth opening, edema, infection and wound dehiscence were evaluated on each visit. RESULT: The mean age of selected patients in both the treatment groups was comparable. The mean age of patients in group I was 45.00 ± 13.33 years whereas in group II the mean age was 44.00 ± 13.13 years. Pain, edema was less in Group I. Mouth opening was less in group II. We did not encountered infection and wound dehiscence in any case. CONCLUSION: Various techniques can be utilized for the closure; regardless of the technique used, success of the surgical procedure depends on effective removal of fistulous tract and complete extermination of any sinus pathology and/or infection. The major factors determining the type of surgery for closure of OAF are dimension and location of the defect. The other decisive factors could be the adequacy and health of adjoining tissue. We observed buccal fat pad to be better option for closure of OAF, despite of its more morbidity; as all the complications were of some time period and when evaluated for long term.
ABSTRACT
Occurrence of central mucoepidermoid carcinoma within the jaw bones from aberrant salivary tissues is extremely rare and accounts for 2%-4% of all central mucoepidermoid carcinoma. Mandible is more commonly affected than maxilla in a ratio of 2:1. The origin of mucoepidermoid carcinoma is controversial and questionable. Central mucoepidermoid carcinoma is frequently misdiagnosed radiographically and clinically as a benign odontogenic tumor or cyst. Hence, it is important to detect malignant signs and histopathological feature of central mucoepidermoid carcinoma of the mandible to confirm the diagnosis. This paper reports a case of central mucoepidermoid carcinoma of the mandible in a 56-year-old patient with review of literature.
ABSTRACT
OBJECTIVE: The objective of this study was to assess the effectiveness of collagen membrane as biological dressing over buccal fat pad (BFP) during crucial postoperative healing phase in the surgical management of oral submucous fibrosis (OSMF). STUDY DESIGN: The study comprised of 40 patients of OSMF of group IVa (Khanna and Andrade). Patients were randomly divided in two groups (20 patients in each group). Group I patients were treated using buccal fat pad only, whereas collagen membrane was used as a covering over harvested BFP in group II patients. Postoperative follow-up was done at 1 week, 3 weeks, 6 months and 1 year. RESULT: Mean postoperative mouth opening achieved in both the groups was comparable at every follow-up visit. Infection was evident in four patients of group I at 1-week follow-up, whereas none of the group II patients developed infection. Pain score was lesser in group II patients as compared to group I. Relapse was seen in two patients in group I and one patient in group II. Time taken for epithelialization was 2-3 weeks in both the groups. CONCLUSION: Although intraoperative time was increased in group II application of collagen membrane reduced infection when compared with group I. Also, the chances of damage to BFP are reduced during the hygiene maintenance at surgical site and jaw-opening exercise. Reduction in pain scores during postoperative period in group II patients was an additional advantage.
ABSTRACT
Background: Circulating miRNAs (miRs) in the biofluids such as serum and plasma act as potential biomarkers for early diagnosis, treatment and prognosis. In the present study, an attempt made to see the expression of miR-21 in serum of 20 cases of Oral sub-mucous fibrosis (OSMF), 20 cases of Oral squamous cell carcinoma and 40 healthy volunteers. The expression of miR-21 was evaluated in relation to different demographical and clinicopathological features such as sex, tobacco, pan-masala, alcohol, smoking and clinical staging respectively with an aim to identify correlation with oral pre-cancer and cancer stages. Materials and Methods: The relative expression level of miR-21 was determined by quantitative real-time RT-PCR (qRT-PCR) in the sera of 20 OSCC, 20 OSMF patients and 40 healthy subjects as a control. Association between expression of miR-21 and OSCC clinical stages and demographical parameters such as sex, pan-masala, tobacco, smoking, alcohol have also been analyzed in detail. Results: The results obtained by t-test revealed significant increase in the expression level of miR-21 in OSCC as compared to OSMF. The study also revealed the positive correlation between higher miR-21 expression and pan-masala chewers as shown by t-test. The statistical test, ANOVA has also indicated a positive correlation between up-regulation of miR-21 in the clinical stages of the OSCC. Conclusion: The results of present study indicated up-regulation of circulating miR-21 in serum of OSCC as compared to OSMF (p=0.001), this study also elucidated the positive correlation between miR-21 expression in OSCC/OSMF patients, only one demographical parameter (Pan-masala) and negative correlation for other parameters such as sex, tobacco, smoking, alcohol etc. Other findings suggested a significant increase (p=0.000) in the expression of miR-21 in clinical staging (I-IV) of oral cancer. More studies are needed to validate it as potential diagnostic and prognostic biomarker for OSMF and OSCC for better management.
