Comparison of an intra-oral approach using a contra-angle hand piece with the transbuccal technique for mandibular angle fracture repair

Magister Chirurgiae Dentium - MChD / Purpose: To compare the intra-oral approach using a contra-angled hand
piece with the standard transbuccal approach in the treatment of mandibular
angle fractures.
Patients and Methods: Thirty patients with isolated fractures of the
mandibular angle were treated by open reduction and internal fixation using
one three-dimensional “strut” or “geometric” Synthes® angle plate. Patients
were selected randomly for placement of two-millimeter self-threading
screws, either through the standard transbuccal technique or with an intra-oral
approach using a contra-angle hand piece. None of the patients were placed
into post-surgical maxillomandibular fixation (MMF). Swelling and pain were
measured pre-operatively and again twenty-four hours after surgery. The
actual cutting time from first incision to placement of last suture was
documented, as well as the perception of difficulty of the specific case by a
single operating surgeon.
Results: No statistically significant difference in perception of pain was
experienced between the two groups of patients during the first twenty-four
hours after surgery. There was also no statistically relevant difference in
cutting time between the two placement techniques. A small statistically
relevant difference (p-value = 0.089) was found in the amount of swelling
post-operatively between the two groups, with more swelling in the control
group.
Conclusion: The use of a contra-angle hand piece to place screws in the
compression band area in a mandible angle fracture is an acceptable
alternative to the transbuccal approach. / South Africa
