Odontogenic infection and length of stay (LOS)
Abstracts / British Journal of Oral and Maxillofacial Surgery 45 (2007) e1–e29
Objectives: This study was conducted to evaluate and compare the degree of Staphylococcus aureus, MRSA and the total staphyloccal airborne contamination during clinical sessions and control days at different areas at the Eastman Dental Hospital. Methodology: Mannitol salt agar (MSA) settle plates were placed at various areas of the clinical areas, corridors and receptions of Oral Surgery, prosthodontics, Periodontology and Conservative departments for three days of clinical activity and three days that the clinics did not operate (control days) for seven hours (9:00–16:00). Following incubation the total number of staphylococcal colonies was recorded the standard laboratory procedures for the identification of Staphylococcus aureus and MRSA were performed. Results: There was significant difference (p < 0.05) in the total mean colony number per plate between Oral Surgery and other clinics. Significantly higher total bacterial counts were found at the reception and non clinical areas compared to those from clinical areas. MRSA was only present in 4 of the 448 samples (0.89%). Conclusions: MRSA in the air of the clinics sampled is extremely low. There is significant difference in the mean colony number per plate between the clinical area and the reception area. doi:10.1016/j.bjoms.2007.07.180 P 78 Odontogenic infection and length of stay (LOS) Navin Vig∗ , Jonathan Collier Barts and The London NHS Trust, United Kingdom Introduction/aims: Odontogenic infections comprise a large part of maxillofacial inpatient workload, and the course of any infection can vary significantly between patients. The aim of this study is to investigate both local and systemic parameters associated with odontogenic infection in adults, and to determine which, if any, correlate significantly with length of stay (LOS). The LOS will act as a proxy marker of severity of infection. Materials/methods: This is a prospective study involving data collection at three London hospitals: the Royal London, Chase Farm and Queen’s (Oldchurch). As well as age and sex, details of the infection (including location, size, duration and fluctuance), presence of trismus, previous antibiotic intake and patient temperature will be recorded for all adult patients with infections deemed serious enough for admission. White cell count (WCC) and C-RP will also be determined. Following admission, further details of the infection will be established, including anatomical space and microbiology. Results and clinical relevance: Sample size will be determined from statistical power calculations based on pilot data already obtained from The Royal London Oral and Maxillofacial Patient Database. A retrospective analysis of the data,

looking at approximately 40 admissions in 2006, may already indicate a correlation between inflammatory markers C-RP and WCC, and LOS. The question is whether any of the above parameters predict length of stay for patients admitted with odontogenic infection, where LOS acts as a proxy for severity. Factors correlating with the severity of infection may facilitate more focused immediate clinical patient management. doi:10.1016/j.bjoms.2007.07.181 P 79 Maxillofacial training is no longer than other surgical specialties Lucy Westcott 1∗ , Malcolm Cameron 2 1 Barts
and The London, Queen Mary’s University London, United Kingdom 2 Addenbrookes Hospital, Cambridge, United Kingdom Introduction: There is a perception that the training pathway for oral and maxillofacial surgery (OMFS) is unduly long and arduous, as consultant oral and maxillofacial surgeons must be doubly qualified and holders of two higher fellowships. Method: We reviewed the data regarding the average age of National Training Number (NTN) holders and GMC data on the year of first registration and the year of entry onto a specialist surgical list for all 9 surgical specialities. Results: The results showed the average age of the surgical SpR populations ranged from 33.5 to 38.2 years with an average age of 36.14 years. OMFS SpR’s average age is 37.69 years. The GMC data showed the average number of months from full to specialist registration ranged from 90.83 months to 135.24 months, with OMFS surgeons having the lowest average. Conclusion: This data suggests that OMFS surgeons are of a similar age to other surgeons whilst in training. OMFS surgeons have the shortest transit time between full GMC registration and entry onto the specialist list. The length of OMFS training even with dual qualification is similar to other surgical specialties. doi:10.1016/j.bjoms.2007.07.182 P 80 Facial nerve dissection (FND) techniques in benign parotid surgery: UK OMFS—ENT consultant survey 2006 Barry O’Regan∗ , Girish Bharadwaj Queen Margaret Hospital, Dunfermline, United Kingdom Background: Two specialties carry out the majority of parotid surgery in the UK.
