A groundbreaking systematic review has analyzed the efficacy of two surgical techniques used in patients with active condylar hyperplasia—proportional condylectomy and high condylectomy. This study, published in the “Journal of Cranio-Maxillo-Facial Surgery,” shows promising findings that could revolutionize the treatment approach for patients suffering from this condition. In this article, we delve into the details of the study, its findings, and what it means for cranio-maxillofacial surgery.
What Is Active Condylar Hyperplasia?
Active condylar hyperplasia is a disorder in which the mandibular condyle, the rounded end of the lower jawbone that articulates with the skull, shows excessive and asymmetrical growth. This can often result in dental occlusion issues, facial asymmetry, and altered aesthetics, which can deeply affect the quality of life and psychological well-being of patients.
Study Overview and Objective
The study, led by Tania Camila Niño-Sandoval et al., aimed to compare the effectiveness of proportional condylectomy and high condylectomy in treating this condition, particularly in terms of the need for secondary surgeries. The research spans multiple databases including Medline (Pubmed), Embase, Scopus, Web of Science, and Cochrane, leading to a qualitative analysis of ten studies and a meta-analysis of two studies. The publication’s DOI is 10.1016/j.jcms.2019.03.024, and it has become a valuable reference for practitioners and researchers in the field of maxillofacial surgery.
Methodology and Findings
The researchers collected data on 259 patients with a mean age of 20.4 years, noting a female to male ratio of 2:1. The quality assessment of the included studies was carried out using the Newcastle-Ottawa scale for cohort studies and the 18-item modified Delphi technique for case series.
Their meta-analysis, which encompassed 52 patients, showed a statistically significant decrease in the need for secondary surgery with proportional condylectomy (p=0.0003). The researchers concluded that proportional condylectomy resulted in superior outcomes when compared to high condylectomy, as it led to the re-establishment of the occlusal plane, decreased facial asymmetries, and therefore, fewer subsequent surgeries.
Implications for Clinical Practice
The study’s results suggest that proportional condylectomy may be more efficient than high condylectomy for patients suffering from active condylar hyperplasia. By establishing a better occlusal plane and reducing asymmetries, this approach potentially lowers the need for additional interventions. This is a significant consideration for surgeons when planning the best course of treatment, aiming for minimal invasiveness, and improving long-term outcomes for patients.
Limitations and Future Research
Despite the positive findings, the researchers acknowledge that there were limitations to the evidence due to the heterogeneity of the studies and the small sample size for the meta-analysis. Therefore, more comparative studies with larger cohorts are necessary to confirm the superiority of proportional condylectomy conclusively.
Significance for Patients
For patients affected by active condylar hyperplasia, the implications of this study are compelling. Choosing a surgical technique that minimizes the need for further interventions can not only reduce medical costs and the risks associated with multiple surgeries but can also lessen the emotional and physical burden on patients.

Conclusion
This study stands as a testament to the importance of evidence-based practice in maxillofacial surgery. The findings favor proportional condylectomy over high condylectomy in reducing the need for secondary surgeries in patients with active condylar hyperplasia. The benefits highlighted could lead to a paradigm shift in treating this complex condition. As new research continues to unfold, the medical community looks forward to refining techniques and providing the best possible outcomes for patients.
