Minimally invasive surgery has revolutionized the treatment of maxillomandibular disorders, particularly those involving maxillomandibular dysmorphology, offering significantly improved clinical, aesthetic, and psychological outcomes. In a retrospective study including 4 cases of maxillomandibular disharmonies collected from the Maxillofacial and Aesthetic Surgery Department at Mohamed VI University Hospital in Marrakech over a 16-month period from January 2022 to April 2023, we present the effectiveness and advantages of minimally invasive surgery in managing this dysmorphology. Maxillomandibular disharmonies represent a true surgical challenge, and the range of treatments proposed in the literature does not always align with the severity of the dysmorphologies in our context.
