Surgical tracheostomy is a commonly provided service by surgical teams for patients in intensive care where percutaneous dilatational tracheostomy is contraindicated. A number of factors may interfere with its provision on shared emergency operating lists, potentially prolonging the stay in intensive care. We undertook a two-part project to examine the factors that might delay provision of surgical tracheostomy in the intensive care unit. The first part was a prospective audit of practice within the University Hospital Coventry. This was followed by a telephone survey of oral and maxillofacial surgery units throughout the UK. In the intensive care unit at University Hospital Coventry, of 39 referrals, 21 (53.8%) were delayed beyond 24 hours. There was a mean (standard deviation) time to delay of 2.2 days (0.9 days) and the most common cause of delay was surgeon decision, accounting for 13 (61.9%) delays. From a telephone survey of 140 units nationwide, 40 (28.4%) were regularly involved in the provision of surgical tracheostomies for intensive care and 17 (42.5%) experienced delays beyond 24 hours, owing to a combination of theatre availability (76.5%) and surgeon availability (47.1%). There is case for having a dedicated tracheostomy team and provisional theatre slot to optimise patient outcomes and reduce delays. We aim to implement such a move within our unit and audit the outcomes prospectively following this change.

Introduction: Sarcomas are a rare group of malignant tumors. This study highlights important findings in 91 cases of non-odontogenic sarcomas of the orofacial region. Materials and Methods: Patients who presented with orofacial sarcoma at the Oral and Maxillofacial Surgery Department of a regional University Teaching Hospital between January 1997 and June 2017 were retrospectively studied. Excluded were cases of Kaposi and odontogenic sarcomas. Data obtained were analyzed using the Statistical Package for Social Sciences (SPSS) version 16 (SPSS Inc., Chicago, IL, USA). Results from descriptive statistics were represented in the form of charts. Results: A total of 91 cases were reviewed and consisted of 51 (56.0%) males and 40 (44.0%) females, with a male to female ratio of 1.3:1. The mandible (n=47; 51.6%) and the maxilla (n=26; 28.6%) were the major sites involved. Osteogenic sarcoma (n=44; 48.4%) and rhabdomyosarcoma (n=16; 17.6%) occurred more frequently. A total of 41 (45.1%) patients had surgery and the common hard tissue procedures were mandibulectomy (n=26; 28.6%) and maxillectomy (n=10; 11.0%). Non-surgical oncological treatment was administered to 32 (35.2%) patients, and this was the only modality of treatment in 8 (8.8%) cases. The period of follow-up Arranged from 1-43 months and within this period; there were 7 (17.1%) recurrences with 1 case of pulmonary metastasis. Discussion: Most recurrences were noted less than one-year post-treatment. There is a tendency for patients to present late and compliance with follow up review is poor in this environment.

The purpose of this article is to analyze the incidence, demographic distribution, type, and etiology of all facial fractures treated by the Department of Oral and Maxillofacial Surgery in A Coruña University Hospital (Spain) from 2001 to 2008. A descriptive and analytic retrospective study evaluated 643 patients treated for facial fracture (excluding nasal and dento-alveolar) by the Department of Oral and Maxillofacial Surgery in A Coruña University Hospital from January 2001 to December 2008. Five parameters were studied: year of the injury, gender, age, fracture type, and etiology. Six hundred and forty-three patients with 793 fractures were included. Of these, 83.2% were males and 16.8% were females. The patients’ age ranged between 18 months and 89 years, with a mean of 37.6 and a median of 33. The major cause of injury was traffic accidents (27%), followed by assaults (20.5%), accidental traumas (20.1%), sports (11%), syncopes (7.8%), rural accidents (6.1%), industrial accidents (5.1%), and suicide attempts (0.3%). In 1.1% of the patients, it was impossible to verify the etiology. The etiology of facial fractures varies from one country to another, depending on the cultural, environmental, and socioeconomic factors. In our study, the most common cause was traffic accidents, closely followed by assaults. The number of fractures due to traffic accidents has decreased in the last 3 years. Rural accidents accounted for a significantly higher percentage of fractures than that observed in other series. The number of fractures receiving a surgical treatment from 2005 to 2008 has progressively decreased.

Objectives: The purpose of current study was to identify particular procedures which are associated with a high risk of glove puncture and thereby assist in limiting the risk of infection, especially those in high risk group. Study Design: Observational study. Setting: Outpatient department of dentistry at Liaquat University hospital, Hyderabad. Period: August 2017 to January 2018. Materials and Methods: In present study gloves perforation were assessed after performing various dental treatments by using Latex Biogel gloves. Total 400 gloves were collected from department of oral and maxillofacial surgery, orthodontics, operative dentistry and prosthodontics, 100 from each department. Simple Water Infla­tion technique was used to test punctures in gloves to determine the number and position of punctures in used gloves. Data collection was done using SPSS version 22.0. Descriptive statistics were computed and differences between groups were assessed through T- test. P-value ≤ 0.05 was taken as statistically significant. Results: Total 400 gloves were examined 100 from each department. Out of 100, 94 (94%) were found perforated from oral & maxillofacial surgery, 90 (90%) from orthodontics, 73 (73%) from prosthodontics & 80 (80%) from operative dentistry. Gloves puncture of left hand were more 292 (73%) than that of right hand 108 (27%) out of 400 gloves. Conclusion: Perforation of Gloves while several dental procedures have been evaluated and resulted that gloves on left hand were at greater risk unambiguously in the procedures in which wires were used, additional precautions like wearing double gloves during these procedures may therefore be indicated.

Knowledge Gaps

Objectives: The aim of this study was to evaluate available knowledge and identify knowledge gaps within the field of oral and maxillofacial surgery, by systematically collecting and evaluating systematic reviews. Twelve specific domains were selected: surgical removal of teeth, antibiotic and corticosteroid prophylaxis, orofacial infections, dental and facial trauma, orthognathic surgery, reconstructive surgery, benign tumors, cysts, premalignant lesions, oral complications of treatment of malignant tumors, hyperbaric oxygen therapy, temporomandibular joint surgery, cost effectiveness of different surgical treatments, and ethics.Methods: The literature search, covering four databases, was conducted during September 2014: PubMed, The Cochrane library, Centre for Reviews and Dissemination and EBSCO dentistry and oral science source. Retrieved systematic reviews were quality assessed by AMSTAR.Results: In all, 1,778 abstracts were identified, of which 200 met the inclusion criteria. Forty-five systematic reviews were assessed as of high to moderate quality. The results disclosed some existing evidence in a few domains, such as surgical removal of teeth and implant survival after sinus lifts. However, in all domains, the search revealed a large number of knowledge gaps. Also of concern was the lack of data regarding health economics and ethics.Conclusions: In conclusion, there is a need for well-conducted clinical research in the fields of oral and maxillofacial surgery.

Fibrous Tumor

A 39-year-old Japanese woman presented to the Department of Oral and Maxillofacial Surgery, Okayama University Hospital, with the complaint of a slowly growing buccal mass. The mass was well defined, had rounded margins, and was free from skin and muscles. A color Doppler echographic examination indicated high flow velocity of the blood surrounding the mass. Contrast-enhanced images on CT and contrast-enhanced T1-weighted images on MRI displayed a homogeneous enhanced mass with a well-defined margin. A fine-needle aspiration biopsy and histological examination were performed. On immunohistochemistry, spindle cells were strongly positive for CD34, STAT6, and vimentin and negative for EMA, S100, and α-SMA. The tumor was removed with extracapsular dissection. The tumor was composed of bland spindle cells proliferating in a patternless arrangement with a collagenous background. Most of the tumor mass consisted of hypocellular areas including ectatic blood vessels. A prominent branching vascular pattern was observed. Immunohistochemistry demonstrated that the tumor cells were positive for CD34, STAT6, vimentin, and Bcl-2, and negative for α-SMA, S100, and EMA. Three mitotic cells were observed per 10 high-power fields, and the Ki-67 index was 5.7%. The morphological and immunohistochemical features were consistent with a diagnosis of solitary fibrous tumor.
