The Influence of Bolus of Methylprednisolone on Postorthognathic Surgery Symptoms: A Controlled Clinical Trial

Abstract

Objective: Despite improvements in maxillary and mandibular osteotomy, complications still result in around 20%. Post and intraoperative standard therapies, based on the use of betamethasone and tranexamic acid, could help to minimize the onset of side effects. The aim of the study was to compare the role of a supplementary bolus of methylprednisolone rather than the standard therapy in the onset of postoperative symptoms.

Methods: The authors enrolled 10 patients, affected by class 2 and 3 Dentoskeletal, submitted to the institution for maxillomandibular repositioning osteotomy between October 2020 and April 2021. Patients were divided into 2 groups as follows: 5 patients (group A ) received standard therapy consisting of the administration of 4 mg of betamethasone, intraoperatively, and 1 g of tranexamic acid in 2 administrations. The remaining 5 patients (group B ) received a supplementary bolus of 20 mg methylprednisolone before the end of the surgery.All patients received, in the postoperative period, 4 mg of betamethasone every 12 hours, for 3 days. Postoperative outcomes were evaluated with a questionnaire evaluating speaking discomfort, pain when swallowing, feeding discomfort, drinking discomfort, swelling, and ache. Each parameter was associated with a numeric rating scale ranging from 0 to 5.

Results: The authors observed that patients treated with a supplementary bolus of methylprednisolone (group B ) had a statistically significant reduction of all postoperative symptoms as compared with patients of group A (* P < 0.05, ** P <0.01 Fig. 1 ).

Conclusion: The study highlighted that the additional bolus of methylprednisolone improved all of the 6 parameters investigated by the questionnaire submitted to patients, resulting in a faster recovery and improvement of the patient's compliance with surgery. Further studies with a larger population are needed to confirm preliminary results.
