Objetivo:  Caracterizar a pacientes con discrepancia negativa transversal del maxilar y necesidad de tratamiento por cirugía ortognática.  Métodos:  Se realizó un estudio descriptivo de corte transversal en 25 expedientes clínicos de pacientes que acudieron al servicio de cirugía maxilofacial del Hospital Clínico Quirúrgico Hermanos Ameijeiras, con discrepancia negativa transversal del maxilar y necesidad de cirugía ortognática entre enero de 2016 y enero de 2020. Se estudiaron los casos por medio de variables cualitativas divididas en epidemiológicas, características faciales y mediciones dentarias. Para el análisis se confeccionaron cuadros estadísticos y como medidas de resumen se utilizaron frecuencias absolutas y relativas.  Resultados:  La frecuencia de la discrepancia negativa del maxilar fue de 13,3 %. Los pacientes de piel blanca fueron los más afectados (80 %) y el principal motivo de consulta fue estético (68 %). La asimetría del tercio inferior y el perfil cóncavo estuvieron presentes en el 44 % y 36 % de los casos respectivamente. Se observó alta frecuencia de pacientes con el tercio inferior aumentado (76 %), mordida cruzada posterior (48 %), mordida abierta anterior (75 %), apiñamiento en la arcada inferior (63,3 %) y lingualización del incisivo inferior (72 %).  Conclusiones:  La discrepancia negativa transversal del maxilar es frecuente en personas con necesidad de cirugía ortognática y con gran afectación estética. Se observó mayor predisposición a padecerla en pacientes de piel blanca.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  Introduction:  Transverse discrepancy of the arches is a skeletal problem not sufficiently studied in persons requiring surgical orthodontic treatment.  Objective:  Characterize patients with negative transverse maxillary discrepancy requiring surgical orthognathic surgery.  Methods:  A descriptive cross-sectional study was conducted of 25 medical records of patients attending the maxillofacial surgery service at Hermanos Ameijeiras Clinical Surgical Hospital with negative transverse maxillary discrepancy requiring orthognathic surgery from January 2016 to January 2020. The cases were studied with qualitative variables divided into epidemiological, facial features and dental measurements. Analysis was based on statistical charts. The summary measurements used were absolute and relative frequencies.  Results:  The frequency of negative maxillary discrepancy was 13.3%. White skin patients were more commonly affected (80%). The main concern was aesthetic (68%). Lower third asymmetry and a concave profile were present in 44% and 36% of the cases, respectively. A high frequency was observed of patients with an augmented lower third (76%), posterior crossbite (48%), anterior open bite (75%), lower arch crowding (63.3%) and lower incisor lingualization (72%).  Conclusions:  Negative transverse maxillary discrepancy is common among patients requiring orthognathic surgery for large aesthetic alterations. White skin patients were found to be more prone to present this disorder.]]></p></abstract>
