Welcome to Groningen!
Dear colleagues,
this year the Dutch association of Oral and maxillofacial surgery (nVmKa) celebrates its 60th
anniversary . in this time frame our specialty has been tremendously changed due to achievements in
knowledge based on scientific evidence and clinical craftsmanship .
One of our fields with major developments is the cranio maxillofacial trauma care; it is only 25 years
back in time that the first possibilities came available to reduce midfacial fractures with mini-plates and
screws, as before the treatment possibilities were mainly related to wire fixation techniques .
nowadays our focus should be on optimisation of care, by combining the possibilities of all different
fields involved together in care paths, which makes complex treatment more efficient and provides
more predictable outcomes .
With the selection of the previous board of the Dutch association to hold their 2016 spring meeting in
Groningen, we feel very honored to be able to focus on this subject of cmF trauma care as a farewell
for prof . ruud Bos . He is the first dedicated professor in cmF trauma in the netherlands, and will retire
this year .
the symposium will focus on the current insights on fracture fixation, the accurate preoperative
imaging and planning, with consideration on esthetic awareness .
the compact university city of Groningen provides us an excellent environment to join each other for
both the academic as well as the social point of the meeting .
On behalf of the Department of OmF surgery Groningen
and the Dutch association of Oral and maxillofacial surgery,
Fred spijkervet
chairman Department of Oral maxillofacial surgery
president Dutch association of Oral and maxillofacial surgery

About Groningen
Some Facts concerning the City of Groningen
Groningen is the major city of the northern netherlands and, with a population of 200,000, the eighth
largest city in the netherlands .
Groningen has a university, a university of applied sciences, a school for fine art and design, an academy
of music and many more training institutes . Because of all these institutes, half the population is under
35, allowing Groningen to be able to call itself the “youngest” city of the netherlands . Besides being a
university city, Groningen is also at the leading edge in the development of research, innovation and
entrepreneurship . in other words, Groningen is a real city of talent .
city of talent is a strategic partnership in which the municipality of Groningen, the University of
Groningen, the University medical center Groningen (UmcG), the Hanzehogeschool Groningen and
the province of Groningen have joined forces .
they are investing half a billion euros in innovation and knowledge infrastructure in the city over the
coming years . a considerable share of the amount will be spent on innovation in the fields of energy,
ict, life sciences and nanotechnology .
Groningen strongly believes in the riches of the arts and therefore generously invests in creative talent .
Besides the many permanent theatres and other performance venues, Groningen hosts a number of
(annual) shows and festivals, attracting visitors in their hundreds of thousands from far and wide . many
Dutch rock groups have seen their careers launched at the Festival eurosonic / noorderslag which is
held each year in January . the noorderzon theatre Festival, which is held each late summer, provides a
mix of young talent, new productions and established performers .
also its wide range of museums is bound to provide a few surprises . they include the museum of
Groningen, the anatomical museum, the northern maritime museum, the niemeijer tobacco
museum, the Gerardus van der Leeuw anthropological museum, the museum of Graphic arts and the
University museum .
Groningen is a city with varied opportunities for living, working, shopping and relaxing . it is rich in
history and offers plenty for the visitor to see . around the Grote markt is a shopping area with a choice
of stores, shops and boutiques providing everything one can possibly wish for . three days a week there
is a busy produce and goods market in the two central squares Grote markt and Vismarkt . When tired
from sight-seeing and shopping you are welcome to enjoy a cup of coffee and more in one of the many
cafés, pubs and restaurants .
10
11
the city center boasts no fewer than 160 bars, cafés and discotheques, and scores of open-air terraces
on which to enjoy a balmy summer evening . there is something for everyone - from the traditional
Dutch ‘brown café’ to the trendiest hi-tech . and because Groningen is the ‘youngest’ city in the
netherlands (there are many students and over half the population are under thirty-five) these bars are
not only lively at weekends, but on weekdays as well . Groningen was elected ‘Best inner city 2007’ . also
with regard to prices there is much variation . the same counts for hotels . there is variation, but hotel
accommodation is reasonably priced .
Of course, the city center is not all bars and cafés . it is also a district in which people live, work, shop
and soak up a little culture . it is rich in history and offers plenty for the visitor to see . the central square,
Grote markt, is undergoing a remarkable transformation in these years .
many newspaper articles, both national and international, have been devoted to the architectural highlights: the renowned museum of Groningen . Buildings such as the remarkable yet reserved public
Library, the ‘organic’ Gasunie headquarters, the nostalgic Waagstraat project and the painstakingly
restored railway station have also been singled out as architectural treasures in their own right .
in the city centre the Groninger Forum will arise; a huge project that will conclude in 2017 . it will be
a meeting place, a center of knowledge and culture, containing the archives and a debating centre . a
cinema, the public library and parts of the Groninger museum will find a place here .
Groningen’s main higher educational institutes - the Hanzehogeschool and the University of Groningen
- have a total of 48,500 students, who are able to enjoy an unrivalled range of opportunities . there are
over 275 different courses on offer . the Hanzehogeschool aims to develop independent, creative and
critical minds, with the ‘new media’ playing an important part in its curriculum . the Hanzehogeschool
includes a music conservatorium and the minerva academy of art .
Some facts concerning the University Medical Center Groningen
the UmcG is the only university medical center in the northern part of the netherlands, and therefore
the final point of referral for many patients .
patients go to the UmcG for basic care as well as highly specialist top clinical and top reference care,
such as organ transplants, complex neuro-surgery, neonatology, clinical genetics, in Vitro Fertilization
(iVF), pediatric oncology, renal dialysis and traumatology . all medical and dental specialties are
represented, as well as education programs for all medical disciplines .
the UmcG focuses on healthy ageing in all priority areas: research, clinical care and education . the
healthy ageing-related research is bundled in the institute of Healthy ageing . this institute forms
the shell in which the healthy ageing activities are embedded, such as the cohort study LifeLines, the
12
UmcG center for Geriatric medicine (UcO) and the european research institute on the Biology of
ageing (eriBa) .
the more than 10,000 employees and 1,300 beds make the UmcG one of the largest hospitals in the
netherlands . it is sometimes called ‘a city inside a city’, because of the architecture, with covered
streets that lead to the nursing units and outpatients clinics . moreover, thousands of employees
provide numerous services to even a greater number of patients and visitors . each year, many symposia
are organized in the hospital, with participants from abroad . there are shops, a branch of one of the
national banks, gardens, as well as lunchrooms, in order to make patients less aware that they are in a
hospital . this philosophy has led to a hospital that is unique in europe .
research at the UmcG is characterized by a combination of fundamental and patient oriented clinical
research . the interaction between these two stimulates the development of new clinical and research
opportunities . problems that occur in the clinical practice act as a catalyst which sets new fundamental
research in motion, whereas fundamental research can come up with new clinical possibilities .
the UmcG is demonstrably among the best scientific educational institutes in the netherlands in
the area of medicine, dentistry and human movement sciences . Groningen is not only renowned for
its successful modernization of scientific education, but also has a reputation for its innovation of
nursing education and competency-based continuing education, training and courses to (para)medics
and nurses . the fact that the UmcG is a forerunner in the development of education and training is
underlined by the hyper-modern UmcG Wenckebach skills center . in this mini hospital, with operating
and patient rooms and an intensive care Unit, healthcare providers from different disciplines and
educational levels undergo virtual and ‘almost real’ training to practice skills, new surgery techniques
and treatment methods . training for other aspects, such as teamwork, is also available in the skills
center . at the bottom of this page, you will find a link to more information .
the UmcG is one of the very few hospitals worldwide that perform all organ transplants . this does
not only concern kidney, heart, lung, liver, and small bowel transplants, but also combined organ
transplants, such as heart-lung, lung-liver, and liver-kidney transplants . the UmcG annually performs
over 150 organ transplants . apart from organ transplants, also skin, thin bowel, heart valve, cornea,
bone and bone marrow transplants are carried out .
the UmcG is one of ten recognized trauma centers in the netherlands . it has all the necessary
specialties and facilities at its disposal to immediately treat patients from serious traffic accidents, work-
related accidents or violent crimes . in addition, the UmcG has its own trauma helicopter . the UmcG’s
catchment area covers one-third of the netherlands . moreover, many locations are remote and difficult
to reach . therefore, a helicopter is indispensable in getting the specialized medical team, the mobile
medical team (mmt), quickly to the scene of an accident . the mmt consists of consultants who can
13
anaesthetize patients on the spot, and are capable of performing small surgical procedures . the trauma
helicopter is especially equipped for accident victims . For them, quick, high-quality treatment is crucial .
the UmcG architectures sets it apart from other hospitals . the influence of the patient has played a
decisive part in this . the UmcG is designed to embody the reliability of a bank and the kindness of a
community center . construction began in 1983 and is still ongoing . architects and builders succeeded
one another, and each of the outpatients’ clinics was designed by a different interior decorator . each
outpatient’s clinic has its own image and unique identity . the building itself does not dominate or
overwhelm, but instead empowers the patients who visit it and the people who work there . this makes
the UmcG one of the finest state-of-the-art hospitals of europe .

Some Facts concerning the University of Groningen
the University of Groningen has a rich academic tradition dating back to 1614 . Out of this tradition rose
a nobel prize-winner, the first woman student and the first woman lecturer in the netherlands, the first
Dutch astronaut and the first president of the european central Bank . Geographically, the university is
rooted in the north of the netherlands, a region very close to its heart .
the university provides high quality research and education in a broad and varied range of fields of
study . it is distinguished by the close bond the University of Groningen creates between research and
education, a bond that does justice to their mutual dependence .
as an institution of scientific research and education the university works at the forefront in its
respective fields . the university undertakes its co-operative relations on the basis of openness
and equality . in these relationships, the university is socially involved, purposeful and creative .
the university stimulates current debate on scientific, social and cultural issues . the University of
Groningen comes across as clear and convincing in such debates .
research and education at the University of Groningen is internationally oriented . students from every
14
continent prepare themselves in Groningen for their international career paths . researchers operating
within an extensive network of cooperation contacts work at the threshold of knowledge, thus
affirming the university’s worldwide renown and reputation .

INTRODUCTION AND AIMto assess the diagnostic acceptability of
low dose cBct and msct protocols for
zygomaticomaxillary fracture diagnosis
METHODSUnilateral zygomaticomaxillary fractures were
inflicted on four out of six fresh frozen human
cadaver head specimen . all specimen were
scanned using two cBct and four msct
protocols where the radiation exposure was
systematically reduced . a blinded diagnostic
routine was recreated where 16 radiologists and
8 oral and maxillofacial surgeons performed 144
randomized image assessments . the presence
of fractures was verified by a dissection of the
zygomatic region and as a gold standard to verify
the outcome of the image assessments .
RESULTSZygomaticomaxillary fractures were correctly
diagnosed in 90 .3 percent (n=130) of the image
assessments . the zygomatic arch was the
most often correctly diagnosed (91 .0%) . the
zygomatic alveolar crest showed the highest
degree of misdiagnosis (65 .3%) . no significant
decrease of correctly diagnosed fracture sites
was found between the regular and low dose
cBct and msct protocols . Dose reduction
did not significant decrease the ability to assess
dislocation, comminution, orbital volume,
volume rendering and soft tissues . OmF surgeons
considered the low dose protocols sufficient for
treatment planning . the effective dose of msct
(129 .9 to 51 .0 µsv) remained well in range of cBct
(122 to 28 µsv) .
CONCLUSIONLow dose cBct and msct protocols do not
decrease the diagnostic acceptability for the
diagnosis of zygomaticomaxillary fractures .

INTRODUCTION AND AIMthe aim of this study was to assess the
characteristics of patients with coronoid fractures
treated in two european centers over 10 years and
to briefly review the literature .
METHODSthis study is based on 2 systematic computer-
assisted databases that have continuously
recorded patients hospitalized with maxillofacial
fractures and surgically treated in two european
centers between 2001 and 2010 .
RESULTSDuring the 10 years, 1818 patients and 523 patients
with maxillofacial fractures were admitted to the
two centers respectively: 21 patients (16 males,
5 females) were admitted with 21 coronoid
fractures and 28 associated maxillofacial fractures .
a mean age of 42 .1 years was observed . the
fractures were mainly the result of motor vehicle
accidents, followed by assaults and falls . the most
frequently observed associated maxillofacial
fracture was a zygomatic fracture (13 fractures) . in
both centers, mandibular coronoid fractures are
treated conservatively unless a severe dislocation
of the fractured coronoid is observed or a
functional mandibular impairment is encountered .
conservative treatment can be used, together
with the open reduction and internal fixation of
associated fractures . the crucial point is to prevent
ankylosis, which may be prevented by correct and
early postoperative physiotherapy and mandibular
function .
CONCLUSIONa coronoid process fracture can be treated
conservatively when there is no severe dislocation
or functional impairment of the mandible . the
main goal is to prevent ankyloses .

repositioning forceps, or fracture reduction
forceps, have been used for fracture repositioning
purposes for decades in orthopaedic and trauma
surgery . part of the commercially available forceps
can also be applied in the maxillofacial area .
However, these instruments are not specifically
designed to fit the volumes and curvatures of the
facial bones .
a methodical design method according
to Kesselring was used to determine the
specifications of a set of repositioning forceps,
dedicated to the bony structures of the skull .
the computer aided Designed (caD) set
of repositioning forceps will be presented .
Furthermore, the findings of a human cadaver
experiment with the first prototypes will be
shown . application in the clinical setting will be
achievable after some design modifications and
accurate production of the revised prototypes .

2. TWO APROACHES OF SECONDARY CORRECTION OF COMBINED ORBITAL-ZYGOMATIC COMPLEX FRACTURES WITH PATIENT SPECIFIC IMPLANTS: THE ORBIT FIRST!

adequate repositioning of the Zmc is promoted
as an essential step in restoring the orbital contour .
if there is a combination of Zmc fracture with a
nOe fracture or the Zmc is comminuted, small
irregularities in the positioning of the Zmc can
easily appear, which may even lead to an increase
of orbital volume . in the treatment of functional
enophthalmos suboptimal alignment can be
corrected by camouflage or re-ostetomizing the
Zmc . most authors prefer a two stage procedure:
Zygomatic osteotomy, followed by an orbital
reconstruction . nowadays, computer assisted
planning facilitates the full digital workflow
which potentially enables the surgeon to control
both steps . Backward planning combined with
additive manufacturing of sawing guides and
implants creates the possibility to plan the orbital
reconstruction before actual positioning the Zmc .
the proof of principle is showed by two different
approaches of secondary reconstruction of orbital-
zygomatic fractures with patient specific implants .

preoperative virtual surgery planning is the most
important step in computer assisted surgery
(cas) . it is possible to transfer the preoperative
planning to surgery with the use of helpful
guides in order to exactly achieve the planned
result . static guidance is delivered with the use
of additive manufactured templates, which are
inserted during surgery and define the planned
position and orientation . in dynamic guidance
image-guided navigation is used .
the combination of these two concepts delivers
additional and extraordinary benefits for surgery .
templates may be rigidly positioned with
navigation and will deliver control at local level, eg
acting as a sawing or drilling mall . navigation can
subsequently be used to assess the overall result
in surgery .
in this teD talk we share our experiences and
promising results of simultaneous static and
dynamic guidance in patients with complex post-
traumatic reconstructions .
