MARDONES M., Marcelo et al. Post-operative results and satisfaction in patients operated of orthognathic surgery during the years 2011-2018 in Hospital San José, Chile. Rev. Otorrinolaringol. Cir. Cabeza Cuello []. 2020, 80, 4, pp.453-460. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162020000400453.


Dentofacial deformities are a set of alterations in the shape, position or size of the maxillary bones. Orthognathic surgery is the surgical treatment of choice for this type of alterations, allowing the replacement of the maxillary and restitution of masticatory, phonetic and respiratory functions, as well as facial aesthetics.


Describe post-operative results and level of satisfaction in patients who opted for orthognathic surgery during the years 2011-2018 by the Maxillofacial Surgery team of San José Hospital.

Material and Method:

Retrospective study, the surgical protocols of 44 patients who underwent orthognathic surgery were evaluated. Inclusion criteria: patients over 15 years old with diagnosis of DDF class II and III not associated with any craniofacial syndrome. A survey was applied to these patients to know the degree of satisfaction with respect to the orthognathic surgery carried out, the presence of loss of neurological sensitivity and its anatomical location, if any. Subsequently, the variables gender, patient age at the time of surgery, loss of neurological sensitivity, time of postoperative evolution and skeletal class were related to the level of satisfaction of patients with orthognathic surgery.


90.9% of patients are satisfied with the results of the surgery. There is no statistically significant relationship between the level of satisfaction patients with orthognathic surgery and the variables, gender, age at the time of surgery, loss of neurological sensitivity (of the mentonian nerve, that gives sensitive innervation to the soft tissue of the chin, lower lip, gum by vestibular of incisors, canine and first lower premolar), time of postoperative evolution and skeletal class.


There is a high level of satisfaction in patients undergoing orthognathic surgery. The five variables analyzed do not influence the level of patient satisfaction after orthognathic surgery.

: satisfaction patients; orthognathic surgery; dentofacial deformities; prognathism; retrognathism.
