Myoepithelioma of the Palatal Minor Salivary Gland: A Case Report.

Myoepithelioma is an uncommon benign tumor of the orofacial region arising from the salivary glands. These tumors are composed of specifically myoepithelial cells lacking ductal differentiation and were initially considered as a type of pleomorphic adenoma. Though they commonly arise from the parotid gland, there are a few cases that emerge from the minor salivary glands of the palate and oral cavity. Myoepitheliomas resemble many other tumors arising from the palate including pleomorphic adenoma. This report depicts a case of myoepithelioma of the minor salivary gland of the palate in a 23-year-old patient and the successful management of the lesion.

Exploration of culturable bacterial associates of aphids and their interactions with entomopathogens.

Aphids shelter several bacteria that benefit them in various ways. The associates having an obligatory relationship are non-culturable, while a few of facultative associates are culturable in insect cell lines, axenic media or standard microbiology media. In the present investigation, isolation, and characterization of the culturable bacterial associates of various aphid species, viz., Rhopalosiphum maidis, Rhopalosiphum padi, Sitobion avenae, Schizaphis graminum, and Lipaphis erysimi pseudobrassicae were carried out. A total of 42 isolates were isolated using different growth media, followed by their morphological, biochemical, and molecular characterization. The isolated culturable bacterial associates were found to belong to the genera Acinetobacter, Bacillus, Brevundimonas, Cytobacillus, Fictibacillus, Planococcus, Priestia, Pseudomonas, Staphylococcus, Sutcliffiella, and Tumebacillus which were grouped under seven families of four different orders of phyla Bacillota (Firmicutes) and Pseudomonata (Proteobacteria). Symbiont-entomopathogen interaction study was also conducted, in which the quantification of colony forming units of culturable bacterial associates of entomopathogenic fungal-treated aphids led us to the assumption that the bacterial load in aphid body can be altered by the application of entomopathogens. Whereas, the mycelial growth of entomopathogens Akanthomyces lecanii and Metarhizium anisopliae was found uninhibited by the bacterial associates obtained from Sitobion avenae and Rhopalosiphum padi. Analyzing persistent aphid microflora and their interactions with entomopathogens enhances our understanding of aphid resistance. It also fosters the development of innovative solutions for agricultural pest management, highlighting the intricate dynamics of symbiotic relationships in pest management strategies.

Effectiveness of promethazine on preoperative and intraoperative sequelae in cleft palate surgeries.

INTRODUCTION: Anxiety and nosocomial infection are the most common reported problems in children undergoing cleft surgeries. Research shows that there is an enigma in the use of antihistamine therapy in children for the management of upper respiratory tract infection. 'Promethazine' is a first-generation H1 receptor antagonist, and antihistamine also has strong sedative effects. Our study aims at evaluating the Effectiveness of Promethazine (Phenergan) in preoperative and intra operative sequelae in cleft surgeries. MATERIALS AND METHODS: This is a single-centre, parallel, randomized, double-blinded randomized control clinical trial, which was conducted among 128 children between 2 and 4 years of age undergoing cleft palate surgery under general anaesthesia. After randomization, the case group was subjected to promethazine syrup 1 mg/kg body weight twice a day, orally for 3 days. The primary outcomes were preoperative anxiety levels which were recorded by children fear scale. The secondary outcomes include preoperative sleep quality and cough rate of children which are recorded by using sleep and cough objective scale respectively. The intraoperative heart rate is monitored with an ECG connected to a monitor. RESULTS: Promethazine causes a reduction in the anxiety level by 70%, 64% reduction in cold and cough, improvement in sleep score by 70% and the heart rate was found to be stable throughout the surgery when compared to the control group. CONCLUSION: As the benefits of promethazine in cleft palate surgery rule over its adverse effects, promethazine is considered safe to be used as premedication for children undergoing cleft palate surgeries.

Comparison of efficacy between MBT preadjusted edgewise appliance and clear aligner therapy among class I crowding cases: A randomized controlled trial.

Background: To compare the efficacy of McLaughlin Bennett Trevisi (MBT) appliance and Clear Aligner Therapy (CAT) among nonextraction Class I crowding cases. Methods: The study sample (60 patients) was allotted into two equal groups (30 patients each) using block randomization wherein Group 1: treated with 0.018" MBT appliance and Group 2: treated with CAT for correction of malocclusion. At the end of treatment (T1), treatment duration, chairside time, laboratory time, number, and type of appointments were noted from treatment record cards. For comparing the acceptability among patients treated with both modalities at T1, the patients were interviewed regarding the comfort and ease of using an appliance with a questionnaire-based survey. Results: The median number of nonscheduled/emergency and finishing stage appointments was significantly higher in Group 1 compared to Group 2 (P-value <0.001). The median duration of treatment at the scheduled, finishing, and overall appointments, was significantly higher in Group 1 compared to Group 2 (P-value <0.001). The median chairside time of all appointments was significantly higher in Group 1 compared to Group 2 (P-value <0.001). The experience with treatment and overall acceptability was significantly higher in Group 2 compared to Group 1 (P-value <0.001). However, mean laboratory time per aligner fabrication in Group 2 was 30.26 ± 3.45 min against no laboratory time consumed in Group 1. Conclusions: CAT significantly reduces treatment duration, chairside time, number of nonscheduled/emergency, and finishing stage appointments in nonextraction Class I crowding cases. Prospective studies with 3D aligner systems are recommended to add further evidence in this regard. Clinical Trials Registry-India Registration No: CTRI/2018/04/013301.

Multidisciplinary Approach to Patient-Specific Implants (PSIs): A Case Report and Review of Literature.

Orthodontic treatment often faces challenges in achieving proper anchorage. While orthodontic mini-implants have gained popularity, no universally accepted design and insertion protocol exists for these implants. However, their relatively modest failure rate indicates their clinical reliability. To address complex geometries in the maxilla and mandible, patient-specific implants (PSIs) have emerged as a solution. PSI is currently employed in various domains of oral and maxillofacial surgery like temporomandibular joint (TMJ), total joint replacement, reconstruction of the facial skeleton, and orthognathic surgery. PSI allows for the creation of customized implant fits, leading to shorter rehabilitation times. This case report presents a multidisciplinary approach involving oral surgery and orthodontics, specifically focusing on the design of PSI, surgical placement of PSI, and use of PSI in maxillary protraction in orthodontics. The report highlights the design process of designing PSI and emphasizes its role in orthodontic treatment. By incorporating PSI as a temporary anchorage device (TAD), enhanced stability, precise control over tooth movement, and accurate repositioning of jaws can be achieved. The collaborative effort between orthodontists and oral surgeons is crucial in integrating PSI into the overall treatment plan. Despite the higher costs associated with PSI, their numerous advantages outweigh these drawbacks. PSI plays a vital role in providing enhanced stability, appropriate treatment plan, and achieving desired treatment in orthodontic and oral surgery procedures.

LC-MS/MS analysis of carcinogenic tobacco-specific nitrosamines in Spodoptera litura using the QuEChERS method.

Nicotine is a highly addictive alkaloid and a neurostimulator found in tobacco that causes addiction in humans and makes tobacco a high-demand commercial product. It is popularly used for recreational purposes and is a harmful substance (Oral LD50 value for rat is 50 mg/kg) and causes addiction. The metabolites of nicotine such as the Tobacco-specific Nitrosamines (TSNAs) are hazardous substances whose metabolites are highly electrophilic and form DNA adducts, which will initiate the process of carcinogenesis. TSNAs are formed during curing, storage and fermentation due to the nitrosation of nicotine and other tobacco alkaloids. TSNAs are used as biomarkers for cancer risk assessment in humans exposed to tobacco and its products. To determine the occasional formation of TSNAs in tobacco-feeding insects, 5th instar larvae of Spodoptera litura and their faeces were analyzed for the presence of N'-nitrosonornicotine (NNN), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) along with the stored tobacco leaves (PT-76) using an Agilent 6470B LC-MS/MS system following ISO/DIS 19290:2015 protocol. The larvae are extracted in a buffered acetonitrile-water extraction and the amount of TSNAs are quantified in multiple reaction monitoring (MRM) mode. 20 [Formula: see text]l of each extracted and cleaned up sample was injected into the LC-MS/MS system for quantification. The Limit of Detection (LOD) and Limit of Quantification (LOQ) were 0.001 mg/kg and 0.005 mg/kg for all the tested nitrosamines. NNN was found to be 0.361 mg/kg, 0.340 mg/kg, and 5.66 mg/kg in insect whole-body samples, faeces, and tobacco leaves, respectively. NNK was found to be 0.060 mg/kg, 0.035 mg/kg and 0.93 mg/kg in insect whole body samples, faeces and tobacco leaves, respectively. However, NNAL was not detected in both the insect's whole body and faeces. Recoveries ranged between 95 and 98% for all compounds when spiked at LOD and LOQ. The presence of TSNAs is a biomarker for cancer risk and their presence in insects would point to cancer risk assessment in tobacco feeding insects and any possible TSNA-detoxifying pathways in insects that might prevent mutagenesis caused these compounds.

Resection and Rehabilitation for COVID-19 Associated Rhino-Maxillary Mucormycosis: A Case Report.

Often, patients with rhino-maxillary mucormycosis present with osteomyelitis and necrosis affecting the involved bone. Therefore, curative treatment involves a combination of antifungal therapy and surgical removal of the necrotic bone. In this case report, a 50-year-old female presented with pain in the right side of her face and was diagnosed with rhino-maxillary mucormycosis involving the right maxillary sinus, posterior maxilla, orbital floor, and zygomatic bone. To address the condition, a total maxillectomy of the right maxilla was performed. The post-surgical defect was packed using cotton leno-weave fabric, impregnated with soft paraffin and containing 0.5% chlorhexidine acetate dressing, which was changed every 3rd day. After a six-month follow-up, satisfactory healing was observed. For, rehabilitation, a simple cast partial denture was used.

Emerging technologies and potential applications of algae in dentistry - A critical review.

Algae are effective predecessors of nutrient foods and preventive drugs, gaining global attraction in recent years. It exhibits potent antiviral, antibacterial, antifungal, anti-inflammatory, antioxidant, anti-glycemic, and cholesterol-lowering properties due to their richness in highly valuable secondary metabolites. Nevertheless, algae produce valuable bioproducts, its application in dentistry is in its primitive stage. This review focuses on the emergence and emerging role of micro/macroalgae as a natural source of therapeutic, preventive, and biocompatible agents in dentistry. Several studies unveiled that Cyanobacteria, Spirulina, and Chlorella species offer high oral antibacterial and antifungal properties compared to gold standard agents. The characteristic of algae to scavenge superoxide and hydroxyl free radicals, fabricate them as an anti-oxidative and anti-cancer agent. Either alone or by synergism with pinnacle therapies they are found to produce promising curative actions against periodontitis by embattling proinflammatory cytokines. Technologies extend the functions of microalgae as a detoxifying agent, potent drug delivery system, and adjunct regenerative material in chronic periodontitis. Its application as thickening, binding, anticariogenic agent in toothpaste, antibacterial agent in mouthwash, and biocompatible agent in dental impression materials remains very primitive. Low-cost and eco-friendly technologies are needed for the production of oral hygiene products using algal biomass.

Determination of salivary cortisol and salivary pH level in gaming teenagers - A cross-sectional study.

Introduction: Internet gaming disorder and cybervictimization has a disproportionate increase during the COVID 19 pandemic. Teenagers and adolescents have high risk for addiction to online gaming. Online gaming increases the stress level of the users affecting the general and the oral health. The study aims to determine the salivary cortisol and salivary pH among the gaming teenagers. Materials and methods: The cross-sectional study recruited 45 gaming teenagers with the mean age of 15.5 years. The participants were stratified according to the type of online gaming played as mind, aggressive and betting gaming. Their salivary pH and salivary cortisol were assessed. The collected data was analyzed using SPSS version 23. Results: The mean salivary pH was found to be less among females playing aggressive games (7.11 ± 0.30) and males playing mind games (7.24 ± 0.16). Salivary cortisol level was found to be statistically high in males (6.66 ± 1.33) and females (7.82 ± 0.66) playing aggressive games. The sub-group analysis of salivary pH and cortisol for gender showed a significant difference in the mean salivary cortisol level (p < 0.05) with no difference in the salivary pH (p > 0.05). Based on the number of hours spent in online gaming, there was a significant increase in the mean salivary cortisol level among the participants playing >3 h (p < 0.05). Conclusion: Salivary cortisol is high among individuals playing aggressive games compared to mind and betting games. Also, salivary cortisol is high in females compared to males with no change in salivary pH.

Evaluation of effect of submucosal administration of depomedrol in management of postoperative sequelae in mandibular fractures: A randomized clinical trial study.

Introduction: The mandible is a commonly fractured bone in the face, a fact related to its prominent and exposed position. Open reduction and internal fixation (ORIF) of mandibular fractures has been associated with trauma to the surgical site and the surrounding tissues. Purpose: The purpose of this study is to evaluate the effects of immediate postoperative submucosal depomedrol administration on postoperative pain, edema, and trismus after ORIF for mandibular fractures. Materials and Methods: We conducted a prospective, randomized, controlled, double-blind study of forty patients who required ORIF for mandibular fractures under general anesthesia. The patients were divided into two groups, an experimental group who received immediate postoperative submucosal 40 mg of depomedrol injection through the surgical incision site, and a control group who did not receive any drug. Pain was assessed using a Visual Analog Scale score and the frequency of analgesic consumption at various postoperative intervals. The maximum interincisal distance and facial measurements were compared before surgery and at 24, 48, 72 h, and 7 days after surgery. Results: Statistical analysis of the data indicated a significant decrease in edema, trismus, and pain in the depomedrol group. No clinically apparent infection, disturbance of wound healing, or other corticosteroid-related complications were noted. Conclusion: The results of our study suggest that submucosal administration of depomedrol injection after ORIF for mandibular fractures is effective in reducing postoperative pain, edema, and trismus.

Stress level of dentists during COVID-19 pandemic in hot spots of Tamil Nadu: A cross-sectional study.

BACKGROUND: The novel 2019 COVID-19 spreads by respiratory and aerosols, and this elevates the risk of dentistry during this pandemic. Widespread disease, in a short time, creates stress and has a psychological impact. The aim of this study was planned to assess the stress level of the dentists living or practicing or studying in hot spots which could help to understand mental status among the general dentists during COVID-19 lockdown. MATERIALS AND METHODS: This cross-sectional study was conducted during the period of August 10 to August 25, 2020, on an Internet platform after getting consent from the dentists and practitioners using the Perceived Stress Scale (PSS). Chi-square association was used. Parametric tests such as independent t-tests and one-way ANOVA were also used. In all instances, P < 0.05 was considered statistically significant. RESULTS: This study had a total response from 1044 dental students and dentists residing in hot spot zones in Tamil Nadu. Out of them, 68.4% were female and 31.6% were male. 37.9% of the participants were dental practitioners and 32.5% were undergraduate students. There is a significant association between age groups and PSS, work style, and PSS. There is no significant association between gender and PSS and degree and PSS. CONCLUSION: This study shows that levels of distress were higher than expected during the COVID-19 pandemic among the dentists and majority of the respondents have moderate-to-high-stress levels. As the unlock has been started throughout the country, it is the right time to work with the authorities and focus on formulating protocols for disinfection and sterilization and work on treating the patients with exact safety measures for the welfare of the patients.

Evaluation of quality of life following dental extraction.

Among several treatment modalities done in dental clinics, dental extractions are the most frequently carried out treatment. Tooth extraction is indicated in cases such as chronic periodontal disease, abscess, root caries, root stumps, fractured teeth, and failed root canal treatments with the persistence of periapical cysts or granulomas, impacted teeth, or to facilitate orthodontic or prosthodontic rehabilitation. The consequence of routine tooth extraction could lead to dentoalveolar diseases, which cause tooth loss. The various complications of surgical procedures are delayed wound healing, postoperative bleeding, remnant bony spicules, and nerve paresthesia. This study aimed to assess the impact of nonsurgical tooth extraction on the quality of life of patients. Institutional patient data from January 2021 to April 2021 were analyzed, in which 2000 patients who had undergone extractions at our dental institution were included in our study. The data evaluating the patients' quality-of-life postextraction were recorded. It included speech variation, social interaction, postoperative pain, sleep impairment, and inability to work. Data obtained were statistically analyzed using SPSS, and results were obtained. Most men (49%) experienced an inability to work compared to women (25%). 38% of females had moderate-to-severe pain, whereas males (21%) had only mild pain. 21% of males are isolated socially due to feeling sick, whereas 20% of females are isolated socially due to pain. Speech was affected more postextraction. Most of the patients could not go to work for 1-3 days following the removal of the tooth. Most of the patients were pleased with the procedure, with their symptoms disappearing after the procedure, and were not worried about dental extractions.

Evaluation of difficulty index of impacted mandibular third molar extractions.

When compared to other teeth, third molars have a greater rate of impaction. Third molars that have been impacted are commonly encountered in dental practice, and it is the reason for complications in third molar surgery. The most commonly performed surgical procedure by dental practitioners is the third molar extraction. Despite a well-planned surgical approach, there are complications in lower third molar extractions. This study analyzes the expected difficulty during surgical removal of lower third molars that are impacted. This study analyzes the expected difficulty during the removal of impacted lower third molars by surgery. With the data from our dental institution database, the difficulty index by Pederson was used to evaluate the difficulty level of the extraction. Using SPSS, data were analyzed and results were obtained. Among impacted left mandibular third molars (38), minimal difficulty in 20.60% of the extractions, moderate difficulty in 29.58% of the extractions, and most difficulty in 2.77% of extractions were present. Among impacted right mandibular third molars (48), minimal difficulty in 18.80% of the extractions, moderate difficulty in 25.78% of the extractions, and most difficulty in 2.47% of extractions were present. According to our study, there is moderate difficulty in impacted lower third molar surgery, and it depends on factors such as systemic status and patient's age, periodontal condition, and complexity of tooth position in the dental arch.

A pilot randomized trial to study the success rate of early precut fistulotomy and its effect on radiation dose in patients with difficult biliary cannulation.

BACKGROUND: Role of precut fistulotomy in reducing fluoroscopy time and the radiation dose in difficult selective biliary cannulation is unknown. METHODS: We performed a randomized trial where patients with difficult biliary cannulation were randomized into 2 groups: early precut fistulotomy (precut five minutes after failed standard biliary cannulation) or late precut fistulotomy (precut fifteen minutes after failed standard biliary cannulation). We compared the success rates of selective biliary cannulation, fluoroscopy time, radiation dose, complication rates, need for repeat endoscopic retrograde cholangiography (ERC) and need for other interventions. RESULTS: Of the 130 eligible patients screened, 40 patients were randomized. The technical success was comparable between early and late group. The fluoroscopy time and radiation dose were significantly less in the early group [4 minutes (3, 6) vs 15 minutes (8, 28), p=0.001] and [1.35 mGy (0.90, 1.63) vs 2.40 mGy (1.58, 3.25), p=0.010] respectively. In the late group, 60% required need for rescue precut fistulotomy. One patient from late group developed post ERC pancreatitis while 1 from early group developed perforation. Three needed other interventions due to failed second attempt. CONCLUSION: Early precut fistulotomy has comparable technical success and reduces the radiation dose as compared to late precut fistulotomy for difficult biliary cannulation.

Determining Association Between Cognitive Function and Oral Health Status among Rural Community Dwelling Geriatrics.

OBJECTIVE: Numerous prospective studies worldwide investigated the association between oral health status and dementia or cognitive decline. No clear agreement has emerged on the association. This study aimed to determine the association of cognitive function and oral health status among community dwelling geriatrics in rural South India. MATERIALS AND METHODS: A cross-sectional study was conducted among community dwelling geriatrics in rural South India by recruiting 211 individuals aged above 60 years. Their cognitive function was assessed using pre-validated community screening instrument for dementia (CSI-D) which has informant and cognitive scale. The data on cognitive function was collected by community health workers in electronic version (Web app). Their oral health status was assessed by World Health Organization (WHO) oral health assessment form in electronic version (Web app). RESULTS: From the logistic regression analysis, it was observed that cognitive impairment showed an association with 1.6- and 1.9-times risk for root caries and a greater number of missing teeth (P ≤ 0.05). No association of other oral health parameters such as gingivitis, periodontitis, dental erosion, and dental trauma with cognitive impairment exhibited. CONCLUSION: From the results, it can be concluded that cognitive impairment has an association with root caries and number of missing teeth which increases the risk for the same and vice versa.

Quality of life among head and neck cancer treated patients in South India: A cross-sectional study.

BACKGROUND AND AIM: The impact of oral health related disease and treatment on the patient's overall well-being and functioning is a topic of growing interest in clinical research and practice. Research shows that there is a significant reduction in the quality of life for the patients throughout the treatment of head and neck cancer. Therefore, the aim of the study is to assess the quality of life among treated head and neck cancer patients. MATERIALS AND METHOD: The cross sectional study was conducted among 225 head and neck cancer patients. The European Organization for Research and Treatment of Cancer (EORTC QLQ C-30), Quality Of Life Head and Neck35" (QLQ-HN35) instruments were used to assess their quality of life. The study population was divided into three groups based on the treatment done: Group I (Surgery), Group II (Surgery and Radiotherapy) and Group III (Surgery, Radiotherapy and Chemotherapy). Independent t-test and one way ANOVA test were done to analyze the data. RESULTS: Trouble with opening mouth (34.66 â€‹± â€‹30.58) was one of the highest rated symptoms among the study population. Salivary dysfunction leading to dry mouth (33.33 â€‹± â€‹34.06), sticky saliva (33.33 â€‹± â€‹26.72) were also found to be severe. Among the three groups, the Global Health Status, Symptom Scale mean scores were more high in Group I, Functional Scale and H&N35 symptoms mean scores was high in Group III however no statistical significance was observed (p â€‹> â€‹0.05). CONCLUSION: Head and neck cancer has severe effects on the quality of life. As observed from the findings of the current study, Global Health Status indicated a healthy level of living among patients who have undergone surgery alone; head and neck symptoms were more severe and problematic among patients who had surgery and radiotherapy. Therefore, assessing health related quality of life can be a factor that is weighed against treatment burden, toxicity, survival benefit. It can be more integral to treatment planning, refining treatment protocols and a better post-operative care and support.

Assessment of post extraction complications in Indians.

Extraction is one of the commonest procedures in dentistry. Therefore, it is of interest to evaluate the post extraction complications in patients undergoing extractions of permanent teeth. A total of 70 adult patients who had undergone dental extractions and presented with post -operative complications were included in the study and evaluated. Data collected was statistically analyzed using SPSS software and results obtained. Most of the patients with post extraction complications were in the age group of 31-40 years (21.6%), followed by 21-30 (20.2%) and 61-70 years (20.2%). Dry socket (39.19%) was the common post extraction complication in our study especially in the age group of 31-40 years. There was a statistically significant association between age of the patients and the post extraction complications (p<0.001). In our study, post extraction complications were commonly observed in age group of 31-40 years with a predilection for males. Dry socket was the most common post extraction complication. Age of the patient has a significant effect on post extraction complications. However, gender, smoking habits and systemic diseases have no influence on post extraction complications.

Laparoscopic cholecystectomy in patients with portal cavernoma without portal vein decompression.

INTRODUCTION: Laparoscopic cholecystectomy (LC) in patients with extrahepatic portal vein obstruction causing portal cavernoma (PC) is considered high risk because of portosystemic collateral veins in the hepatocystic triangle. The literature is limited to isolated case reports. We describe our experience of LC in patients with PC. PATIENTS AND METHODS: Data of patients with PC who underwent LC for symptomatic gallstones or related complications was reviewed. Patients with simultaneous cholecystectomy with splenorenal shunt and open cholecystectomy were excluded. Pre-operative evaluation consisted of complete blood count, international normalisation ratio and liver function tests, ultrasound of the abdomen with Doppler, contrast-enhanced computerised tomography, magnetic resonance cholangiopancreatography and esophagogastroscopy as indicated. A standard four-port LC was performed. The technical principles followed were to avoid injury to the collateral veins, liberal use of energy sources and division of dominant collateral veins between clips. RESULTS: Seven adult patients including three females underwent LC. Three patients had thrombosis of previous surgical shunt with persistent PC. The remaining four patients did not have any indication for shunt surgery. Successful LC was performed in six patients. The median duration of surgery was 170 (130-250 min). Blood transfusion was not required. All the patients had uneventful post-operative recovery. The histopathology of gall bladder consists of acute cholecystitis in three patients and chronic cholecystitis in four. CONCLUSION: LC is feasible in patients with PC at a centre with experience in both laparoscopic and portal hypertension surgeries. Excellent outcome with low rate of conversion to open surgery can be achieved.

Comparison of Endoscopic Turbinoplasty Versus Conventional Partial Inferior Turbinectomy in Chronic Hypertrophic Rhinitis.

To compare the benefits of endoscopic turbinoplasty and conventional partial inferior turbinectomyin terms of symptomatic relief of the post operative subjective and objective outcomes in patients with chronic hypertrophic rhinitis. A comparative longitudinal study was carried out over a period of 18 months. 60 cases were assigned randomly into two groups-group A (endoscopic turbinoplasty) and group B (conventional partial inferior turbinectomy) and post-operatively were followed up to 6 months to look for postoperative subjective and objective outcomes. Symptomatic improvement in nasal obstruction was found to be consistently better in group A patients at postoperative days 7 and 15, but both groups achieved comparable symptom relief at the third month. A statistically significant difference in SNOT 22 scores were observed between the two groups at all follow-ups. Relatively higher rates of post-operative morbidities were observed in group B at the 7th and 15th postoperative days. Endoscopic turbinoplasty may be better than conventional partial inferior turbinectomy in terms of improvement in nasal obstruction and decreased postoperative morbidity in the immediate postoperative period.

Changes in posterior airway space and mandibular plane hyoid distance following mandibular advancement DO.

AIM: To study the changes in posterior airway space (PAS) and mandibular plane hyoid (MPH) distance following mandibular advancement using distraction osteogenesis (DO). SUBJECTS AND METHODS: A prospective study was conducted at a tertiary care dental center from May 2009 to May 2014. Twenty-five consecutively operated patients of mandibular hypoplasia who underwent mandibular advancement using distraction with at least 12 months follow-up were included in the study. The study group comprised 15 males and 10 females with an age range of 15-30 years (mean 22 years). Presurgical and postsurgical cephalometric changes were compared to determine the changes in PAS and MPH distance. RESULTS: The mean distraction achieved was 14.50 mm. The mean preoperative MPH was 18.88 mm and mean postoperative MPH was 13.16 mm with a resultant reduction by 32%. Mean preoperative PAS was 6.48 mm and mean postoperative PAS was 11.08 mm. Mean increase in PAS was 75%. Mean preoperative and postoperative SNB values were 75.4° and 79.52°, respectively. The results were statistically analyzed using paired "Student's t-test." CONCLUSION: From this study, it is concluded that statistically significant changes were achieved in MPH and SNB. Although change in PAS was statistically insignificant, it may have clinical applications, especially in the field of Phase II surgical management of obstructive sleep apnea.
