INTRODUCTION: Orthognathic surgery practices depend on patient characteristics, which may vary from one country to another, and they may also evolve with new techniques and developments.
OBJECTIVE: The aim of this study is to describe the epidemiological characteristics of patients and orthognathic surgical procedures performed in the maxillofacial surgery department at Pitié-Salpêtrière University Hospital (Paris, France).
MATERIAL AND METHODS: This was a retrospective study covering the period from January 2017 to December 2020. All patient records from this period were reviewed. The following data were collected: demographic characteristics (age at the time of surgery, gender), type of dentofacial deformity (Angle class I, II, or III, transverse and vertical facial dimensions), and type of surgical procedure.
RESULTS: A total of 667 patient records were included. Analysis of the parameters studied showed a female predominance (60.82%) with a mean age of 27.9 years. The most common Angle dental class was class II (56.4%) followed by class III (35.4%). Long-face patients accounted for 47.86% of the sample, short-face 41.61%, and balanced-face 10.53%, with 44.4% exhibiting facial asymmetry. A reduced transverse dimension was observed in 22.12% of cases. The most common orthognathic procedure was maxillomandibular osteotomy (56.08%), followed by mandibular osteotomy (20.7%), and maxillary osteotomy (19.12%). Overall, 23.4% of patients underwent dental extractions during surgery and 4.4% of records reported reinterventions (revision surgery, hardware removal, or pseudarthrosis repair).
DISCUSSION: Class II malocclusion is common in the French population and is frequently encountered in orthodontic-surgical protocols. According to the literature, maxillomandibular surgery appears to be on the rise.
CONCLUSION: The results of this four-year retrospective study reveal a predominance of young, female patients. Class II malocclusion was the most frequent, and maxillomandibular surgery was the most commonly performed procedure. Given the lack of epidemiological data, further studies should be conducted to assess variations in surgical practices across different geographic regions and types of institutions (private, public, etc.).
