Orthognathic Surgery in Adults with Craniofacial Clefts: Evaluating the Need for Maxillary Advancement and Facial Aesthetic Improvement

Background: Craniofacial clefts represent the most common congenital malformation in the head and neck region. Although most patients undergo primary cleft repair in childhood, many still present midfacial growth deficiencies in adulthood. This study aimed to evaluate and compare the incidence and indications for orthognathic surgery in adult patients with cleft lip (CL), cleft lip and alveolus (CLA), cleft lip and palate (CLP), and isolated cleft palate (CP). Materials and Methods: Sixty adult cleft patients (36 males and 24 females) born with a cleft and with a mean age of 19.51 ± 1.83 years were retrospectively enrolled in this study. All patients had undergone primary lip and palate repair during childhood at the Oral and Maxillofacial Surgery Service of “Mother Teresa” University Hospital Centre in Tirana. Clinical records, orthodontic documentation, and cephalometric data were reviewed to determine the indication for orthognathic surgery. Results: The statistical analysis showed that orthognathic surgery was deemed necessary in 30% patients, including ten males (56%) and eight females (44%). The most prevalent type of cleft was CLP, accounting for 35% of all patients, and it showed the highest surgical indication rate (83.3%). Cleft patients and the need for orthognathic surgery were evaluated according to the skeletal malocclusion in three planes. The need for surgery was more prevalent in patients with skeletal class III malocclusion with maxillary hypoplasia (83.3% of surgical cases), those with anterior and posterior crossbite (21.7% of all patients), and in deep bite patients (16.7% of all patients). Additionally, all patients with facial asymmetry (15%) required orthognathic surgery, highlighting the strong association between asymmetry and surgical indication. Conclusions: Patients with craniofacial cleft, especially those with CLP and combined maxillary deficiencies, demonstrate a significantly higher need for orthognathic surgery. Quantitative assessment supports the necessity of a multidisciplinary treatment approach to address persistent skeletal discrepancies and optimize functional and aesthetic outcomes in adult cleft patients.
