Mandibular Third Molars and Their Influence on Mandibular Angle Fracture Fixation

| 要約: | Introduction: Mandibular fractures occur commonly in
Singapore and 32% involve the angle. The third molar (M3)
predisposes the angle to fracture and is often involved in the
fracture site. During fixation, it is often routinely retained but
few studies question if this impacts surgical repair and postoperative healing and recommend if it should continue to be
done.
Aim: To describe all operatively treated mandibular angle
fractures (MAFs) with M3 retention over 10 years in a single
centre and report any effect of routine M3 retention on fracture
fixation or post-operative complications.
Materials And Methods: The present study is a retrospective
one including all operatively treated MAFs with M3 retention in
the National University Hospital, Singapore between January
2001 and December 2010. Subjects below 16 years of age
and those with incomplete follow up or Computed Tomography
(CT) data were excluded. Hospital records were reviewed
for demographic variables and (Seeman’s 7) postoperative
complications. OsiriX version 7.5 (Pixmeo., Switzerland) used to
characterise the fracture and M3. Analysis was performed using
Statistical Package for Social Sciences version 23 (IBM, USA).
Results: 23 cases (25 MAFs) were included and the average
subject was a 28.8 (SD 4.59) year old male (88%) with a left
(64%) simple (84%) MAF with fracture line involving the M3
socket (76%). Concomitant mandibular fractures featured in 14
cases (56%). Most M3 were Class II (76%), Class B (68%) and
distoangular (52%). Mean intraosseous M3 length and diameter
was 8.33mm (SD 2.09) and 11.70mm (SD 1.89) respectively. The
mean mandibular thickness and width was 29.25mm (SD 5.41)
and 16.92mm (SD 2.03) respectively. Despite M3s of varying
morphology, successful repair was carried out in all cases.
Conclusion: Unless the M3 impedes fixation, it need not be
removed during fracture fixation. |
