“…A deformidade dentofacial (DDF) é definida como uma anormalidade anatômica do esqueleto facial que compromete a oclusão e a aparência e pode ser percebida desde o nascimento, durante ou após o desenvolvimento ósseo, predispondo o indivíduo a prejuízos funcionais, estéticos e biopsicossociais. A DDF atinge cerca de 20% da população mundial e pode ser classificada em classe I, classe II e classe III de Angle (TRENCH; ARAÚJO, 2015;CAVALCANTI et al, 2021;POSNICK;TREMONT;KABAN, 2021;SANTOS;SANTOS;GUIMARÃES, 2021).…”

A deformidade dentofacial (DDF), de prevalência de 20% na população mundial, prejudica a funcionalidade da mordida, a estética orofacial e a qualidade de vida dos pacientes que possuem uma de suas três classificações, I, II e III. A cirurgia ortognática é uma das principais intervenções para correção da DDF e, dentre suas técnicas, há a Le Fort I, que pode apresentar complicações, assim como as outras modalidades, destacando-se em muitas pesquisas com menos incidência desses eventos. Nesse contexto, este estudo tem o objetivo de evidenciar, por meio de revisão integrativa, as complicações pós-cirúrgicas orofaciais mais prevalentes em pacientes adultos e pediátricos submetidos ao método de osteotomia Le Fort I. Resgatou-se 05 artigos nas bases de dados PubMed/MedLine, Scielo, Google Acadêmico e BVS/BIREME , em sua maioria estudos retrospectivos, que destacaram sangramentos, infecção, instabilidade óssea e prejuízos neurais como algumas das principais e evitáveis complicações relacionadas à Le Fort I. Nesta pesquisa, destaca-se a importância de novas revisões, com metanálise, para avaliação das estratégias de prevenção e controle de tais eventos.

“…Few studies in the literature focus on speech parameters in subjects with class II malocclusion. The authors have observed compensations such as mandibular advancement, lingual interposition, 15 and unsystematic articulatory imprecision 16 during the production of consonants. Bilabial sounds have also been studied, because some compensatory strategies can be implemented in order to overcome the anatomical disproportion.…”

Introduction The acoustic analysis of speech (measurements of the fundamental frequency and formant frequencies) of different vowels produced by speakers with the Angle class II, division 1, malocclusion can provide information about the relationship between articulatory and phonatory mechanisms in this type of maxillomandibular disproportion. Objectives To investigate acoustic measurements related to the fundamental frequency (F0) and formant frequencies (F1 and F2) of the oral vowels of Brazilian Portuguese (BP) produced by male speakers with Angle class II, division 1, malocclusion (study group) and compare with men with Angle class I malocclusion (control group). Methods In total, 60 men (20 with class II, 40 with class I) aged between 18 and 40 years were included in the study. Measurements of F0, F1 and F2 of the seven oral vowels of BP were estimated from the audio samples containing repetitions of carrier sentences. The statistical analysis was performed using the Student t-test and the effect size was calculated. Results Significant differences (p-values) were detected for F0 values in five vowels ([e], [i], [ᴐ], [o] and [u]), and for F1 in vowels [a] and [ᴐ], with high levels for class II, division 1. Conclusion Statistical differences were found in the F0 measurements with higher values in five of the seven vowels analysed in subjects with Angle class II, division 1. The formant frequencies showed differences only in F1 in two vowels with higher values in the study group. The data suggest that data on voice and speech production must be included in the protocol's assessment of patients with malocclusion.

“…The degree of the DFD may vary, ranging from slight asymmetries without functional and/or aesthetic repercussions to significant changes that affect the entire functioning of the stomatognathic system, and sometimes, the respiratory system 2 . There is a close relationship between DFD and sleep-disordered breathing, and it is estimated that several individuals with DFD who are candidates for orthognathic surgery experience obstructive sleep apnea syndrome (OSAS) 3 .…”

To determine the association between cephalometric measurements and polysomnographic parameters in Brazilian patients with midface deficiency. This was a primary, clinical, observational, longitudinal, retrospective, analytical, and single-center study. Forty-eight patients with midface deficiency were divided into two groups as follows: those who underwent surgically assisted rapid palatal expansion (SARME) and those who received maxillary advancement (MA). Pre- and post-operative cephalometric and polysomnography measurements were obtained. Pearson's correlation was used to verify the presence of any significant associations between PSG scores and cephalometric measurements. Associations between BMI (Body Mass Index) and AHI (Apnea Hypopnea Index) as well as arousals were observed. In the SARME group, associations between AHI and SNA, UAS and MP-H, arousals and SNA, and Co-A and MP-H were noted. Associations between AHI and Co-A, PoOr-A and MP-H, arousals and UAS, and between minimum saturation of O2 and SNA, SNB, and Co-A were observed in the MA group. This study demonstrates the alterations in the middle third of the face that were related to sleep disturbance. In addition, it shows the associations between the polysomnographic parameters and the cephalometric representations corresponding to the analyzed deformities and transverse or anteroposterior maxillary deficiencies.
