Abstract

Background

Sagittal split ramus osteotomy (SSRO) is an accepted and standard procedure to address mandibular corpus deficiency. The relapse following the mandibular advancement has a negative impact both on clinician and patient.

Purpose

To analyse the hard tissue changes and to investigate relapse following SSRO advancement procedure.

Materials and Methods

A retrospective review of 21 patients treated by bilateral SSRO advancement at our institute was conducted. Lateral cephalograms obtained at pre-treatment (T1), pre-surgery (T2), 2 months (T3) and 2 years post-surgery (T4) were evaluated by an independent investigator. The data T2–T3 revealed immediate postoperative changes, and T3–T4 revealed skeletal relapse following surgery after 2 years.

Results

Twelve females and nine males with age ranging from 16 to 24 years underwent mandibular advancement. The mean follow-up period was 2 years 7 months ± 4 months. The mean mandibular advancement at pogonion was 5.1 ± 1.25 mm with significant improvement in SNB, ANB, CoGn, maxillo-mandibular differential and SN:GoPg ratio following surgery. Comparison of the outcomes following surgery revealed that the mean relapse at pogonion was 0.2 ± 0.44 mm. B point, mandibular corpus length, anterior and posterior facial height remained stable with no significant relapse following mandibular advancement.

Conclusion

Sagittal split ramus osteotomy within the range of mandibular advancement is a stable procedure.
