masticatory function and improve facial profile and speech. A suitable implant site requires satisfactory width, height and quality of bone. Reconstruction of hard tissue defects therefore will need to be tailored to meet these needs. The aim of this study was to assess the compatibility of five commercially available dental implant systems: Biomet 3i, Nobel Biocare, Astra Tech, Straumann and Ankylos, for placement into fibula osseous vascularised free flap. Method: Digital radiographs of fibulas from 142 patients in the archives of the Department of Radiology in University College London Hospital were analysed. Additionally, 60 dry fibular bones, 30 left and 30 right side, from the collection of the Department of Anatomy, University College London, were also measured. Results: In the fibula dry bone 90% of the samples measured had a width of 13.2 mm. Fibulas measured on radiographs had a width of 14.3 mm in 90% of the samples. The standard stock sizes available of the dental implants analysed in this study were: length: 7–19 mm and width: 3.25–7 mm. Conclusion: This study concludes that the width of fibula is sufficient for placement of most standard sized dental implants. The study also provides a guide for choosing a suitably sized implant. doi:10.1016/j.bjoms.2009.06.110 84 Big brother is watching you! Activity and performance data recorded about us and how it is used Michael Bater Basingstoke and North Hampshire Hospital, Basingstoke/Royal Surrey County Hospital, Guildford, United Kingdom Background: We have entered a period where our outcomes are under greater scrutiny than ever before and whether we like it or not information is continually being recorded about our individual activity and performance. This data is collected and held both locally, within our own trusts, and centrally, through multiple independent agencies, providing ongoing statistics to the Department of Health. Contents: Types of locally held data will be discussed, along with the various ways hospitals use this information in their relationship with primary care trusts. An overview of the various agencies that collect data centrally will be undertaken, along with clarification of their often confusing titles (CHKS, HES, Dr Foster, NCIN, CORESS, NCEPOD, etc.), and an explanation of how the information is used. Clinical relevance: As Oral and Maxillofacial Surgeons it is extremely important that we are all aware of the information being recorded about our day-to-day activity and performance, not least as this data is easily available to hospital managers and our patients. Equally, we should also have
an understanding of how we can use this material to develop our service for patient benefit. doi:10.1016/j.bjoms.2009.06.111 85 In a fragile cardboard box . . . a little piece of history Carrie Newlands Royal Surrey County Hospital, Guildford, United Kingdom Sir Harold Gillies (1882–1960) is widely regarded as the father of maxillofacial plastic surgery. During World War II, he held the post of Consultant to the RAF, the Ministry of Health and the Admiralty. His clinical work was based at Rooksdown House, near Basingstoke. Much of the historical material from his work at Sidcup in WWI, and some from Rooksdown in WWII, is kept in the Gillies archive at St Mary’s Hospital Sidcup, with artwork collections held at the English Royal College of Surgeons. In 2008, a fragile cardboard box carrying the faded slogan . . . “Pick up an English Apple” emerged from a forgotten cupboard in the Maxillofacial laboratory at North Hampshire Hospital in Basingstoke. Inside was a collection of 24 sets of medical notes of injured patients treated by Gillies between 1940 and 1945. The original folders held clinical notes, photographs, artist’s records of surgical procedures and letters, many between Gillies and the patients’ families. This talk discusses this little piece of history, and the lessons it offers. doi:10.1016/j.bjoms.2009.06.112 86 Can orbital fat, muscle and haematoma be differentiated using computer tomography region of interest analysis in the evaluation of orbital floor injuries? Kavin Andi ∗ , J. Makdissi, S.B. Holmes Barts and The London NHS Trust, United Kingdom Introduction: Orbital injuries can pose significant diagnostic challenges particularly in the young where there may be few clinical signs to aid the clinician. Often this diagnostic dilemma results in a period of observation as oedema resolves or alternatively, surgical intervention based on the presumption of herniated orbital contents within the maxillary antrum. Aims: We hypothesised that by measuring the attenuation coefficient of the orbital floor the decision to observe or surgically intervene could be made with additional quantitative data. Methods: Forty-seven patients with isolated orbital floor injuries identified on CT scans were recruited. Patients with preexisting antral disease were excluded. All CT scans were reported by a single Maxillofacial radiologist. Details including age, sex, mechanism of injury, type of fracture and operative findings were recorded. A region of interest analysis
