RESTIT : Evaluation of Resorbable Osteosynthesis Devices Versus Titanium in Maxillofacial Surgery

Not Applicable

• Conditions: Maxillo-Facial Surgery

• Registration Number: NCT00240669
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

Primary objective : To evaluate the quality of fractures setting and osteotomy of the facial massif osteosynthesised with resorbable device PLLA/PGA compared with usual Titanium plates.

Secondary objective :

* To evaluate the resorbable device ergonomy versus Titanium.

* To evaluate the clinical tolerance of resorbable device versus Titanium.

Hypothesis :

Osteosynthesis with resorbable device demonstrates a non inferiority success probability regarding the success observed in osteosynthesis with Titanium, with a less important probability of re-operation.

Study duration : 14 months for each patient.

Study treatment :

* Group I : Resorbable device PLLA/PGA.

* Group II : Titanium device.

Study visits :

- Screening visit - Baseline with randomization and surgery - Day1 - Day 21 - Day 45(Traumatology)/Day 90 (orthognatic) - Month 6,12 and 14.

Randomization : Stratification by centres, mono or bimaxillar surgery and traumatologic or orthognatic criteria.

Primary Outcome Measures

Name	Time	Method
The quality of fractures setting and osteotomy of the facial massif osteosynthesised with resorbable device PLLA/PGA will be evaluated by the notion of unperfect resuts.

Secondary Outcome Measures

Name	Time	Method
infection,
Evaluation of device ergonomy :
The operative time of each surgery will be monitored, to compare operative duration of operations ; the only variable will be the osteosynthesis method.
Clinical tolerance of the devices
pain (Visual Analogic Scale),
local inflammation,
scar disunion,
subcutaneous or submucous palpation of the plates.
