Comparative Study of Skeletal Stability between Postoperative Skeletal Intermaxillary Fixation and No Skeletal Fixation after Bilateral Sagittal Split Ramus Osteotomy: an 18 Months Retrospective Study

Abstract

ObjectivesTo compare the effect of preoperative and postoperative antibiotics therapy on postoperative sequelae after impacted mandibular third molar extractions.Material and MethodsThis was a prospective study conducted at Department of Oral and Maxillofacial Surgery of the Lagos University Teaching Hospitalon consecutive patients with impacted third molar extractions for a 12 month period. Group I (n = 31) had administration of 1 gram of oral metronidazole and 1 gram of amoxicillin capsules 30 minutes preoperative and Group II (n = 31) had 500 milligrams of amoxicillin capsule 8 hourly and 400 milligrams of metronidazole tablets administered post operatively for 5 days. Pain, facial swelling and mouth opening assessment were done postoperatively and on days 1, 3 and 7.ResultsThe general pattern of postoperative pain, regardless of antimicrobial use revealed that pain increased from day 1 to day 3 postoperatively and began to decrease in intensity subsequently up to the seventh day. There was however a statistically significant difference (P = 0.0001) between the two groups on the 7th postoperative day with the subjects in Group I showing lower pain intensity. The mean difference of the facial width on days 1 and 3 was significant (P = 0.04 and P = 0.0001 respectively) with subjects in Group II having a reduced facial width compared to those in Group I.ConclusionsThis study suggested that the administration of preoperative or postoperative antibiotics showed no marked differences in the degree of postoperative sequaele that occur after impacted mandibular third molar extractions.

Effects of platelet-rich fibrin and piezosurgery on impacted mandibular third molar surgery outcomes

“…These inflammatory complications still remain an important factor for patients and surgeons are responsible for developing a strategy to reduce the risk of complications and improve postoperative healing [ 4 ]. Many attempts have been made to reduce postoperative outcomes following third molar surgery, including platelet-rich plasma administration [ 5 ], cryotherapy [ 6 ], preoperative and postoperative antibiotics [ 7 ], osteotomy using high or low speed rotary instruments [ 8 ], wound draining [ 9 ], the use of different kinds of flaps [ 10 ], postoperative ice packs [ 11 ], corticosteroids [ 12 ], analgesics [ 13 ] and laser [ 14 ].…”
