Objectives: Postoperative nausea and vomiting (PONV) is considered as one of the most incessant and anguishing factors for patients who have surgery under general anesthesia. The occurrence of PONV after orthognathic surgery can lead to dehydration, infection, bleeding at the surgical site, and patient discomfort, all of which leave a patient with a negative impression of anesthesia and surgery. The purpose of this study is to assess the incidence of PONV after orthognathic surgery and to correlate it with factors related to patient, anesthesia, and surgery. Materials and Methods: A 10-year retrospective survey was done for patients who underwent orthognathic surgery between January 2008 and March 2018. The incidence of PONV was evaluated, correlations with factors related to patient, anesthesia, and surgery were studied, and the duration between the end of surgery and the occurrence of the first episode of PONV was tabulated. Results: The medical records of 109 patients were screened, out of which 101 satisfied the inclusion criteria. Amongst these patients, 60 patients (59.4%) suffered from PONV. Patient's sex, induction agent used, intravenous fluids administered intraoperatively, duration and type of surgery, and the presence of a nasogastric tube were seen to have a significant influence on precipitating PONV. It was noted that among the patients who suffered from PONV, 61.7% of them experienced it 48-96 hours after the end of surgery. Conclusion: Despite the improved anesthetic equipments, drugs, and surgical techniques currently used, the incidence of PONV was high in our study. Certain factors that were seen to influence PONV in this study need to be considered in order to develop an efficacious protocol to reduce PONV in orthognathic surgeries.
Introduction Oral submucous fibrosis (OSF) is an insidious disease affecting the oral cavity, pharynx, and upper digestive tract. It is characterized by a juxtaepithelial inflammatory reaction followed by fibroelastic change in the lamina propria and associated epithelial atrophy. Higher levels of TGF-b present in patients with OSF could be responsible for impetus to remnants of Reichert's cartilage present in styloid complex leading to partial or complete ossification of associated ligaments. So, a study was conducted to evaluate the elongation of the styloid process in patients with OSF by using panoramic radiographs. Materials and Methods Panoramic radiographs of patients with OSF were studied from 2007-2011. The apparent lengths of styloid process were measured with the help of divider and steel metric ruler. The length of the styloid process and/or ossification of stylomandibular ligaments which were longer than 30 mm were considered. Results Out of 47 patients, 35 patients (34 males & 1 female) met the inclusion criteria. Eleven patients (31.4%) were found to have elongated styloid processes which included 10 male patients and 1 female patient. Conclusion It had been estimated that between 2 % and 4% of the general population presents radiographic evidence of an ossified portion of the styloid complex. The high incidence of elongation of styloid process (31.4 %) in patients with oral submucous fibrosis highlights that progressive OSF might have some influence on elongation of styloid process.
Fibro-osseous lesions of the jaws can have certain histologic features in common with central giant cell granuloma (CGCG) including the presence of multinucleated giant cells. The clinical, radiologic and histologic features of these lesions should be carefully evaluated to distinguish between these conditions. Fibro-osseous lesions of the jaws are a heterogenous group of lesions characterized by the replacement of normal bone by fibrovascular tissue containing newly formed mineralized material. Central giant cell lesions are defined as an intraosseus lesion consisting of cellular fibrous tissue containing multiple foci of hemorrhage and aggregation of multinucleated giant cells. These lesions may sometimes lead to a confusion in their diagnosis as many pathologists report them taking into consideration one of the prominent histopathologic feature. These confusions may be because of the small number of cases reported in the literature with uncertain clinical, radiographic and histopathologic features of these lesions. So even surgeons may end up treating these lesions inadequately or patients may need to undergo multiple surgeries. We report such a case of Juvenile ossifying fibroma associated with CGCG and discuss the clinical, imaging, histologic, and treatment aspects of this hybrid lesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
