Conventional arthrocentesis was able to change the effusion variable, whereas the single needle arthrocentesis was not. Both techniques were responsible for altering the position of the mandibular head or the disc-head complex, projecting them to a more anterior position related to the increase in the final maximum interincisal distance.
The objective of this study was to compare single-needle arthrocentesis with distension of the upper compartment of the temporomandibular joint (TMJ) with the conventional two-needle arthrocentesis. Twenty-six patients with articular disc displacement without reduction (DDWOR) were included in the study and assigned to two groups (n = 13): single-needle arthrocentesis with distension of the upper compartment of the TMJ (1N) and conventional two-needle arthrocentesis (2N). The maximum interincisal distance (MID) and TMJ pain as measured by the visual analog scale (VAS) were compared. MID and VAS data were obtained: before (T1), seven days after (T2), fifteen days after (T3), one month after (T4), three months after (T5), six months after (T6), nine months after (T7), and one year after the arthrocentesis procedures (T8). Considering each group individually, results of the VAS scores and MID measurements showed a significant difference between T1 and T2–T8 (p < 0.001) in both groups. Between two groups, results show no significant differences (p > 0.05). Both techniques tested were effective in reducing pain and increasing MID. Due to the advantages over the conventional two-needle arthrocentesis, single-needle arthrocentesis with distension of the upper compartment should be considered as the first treatment option for patients with painful hypomobilized TMJ of DDWOR.
Introdução: O trauma representa um considerável problema de saúde pública, devi- do ao elevado índice de morbidade, incidência e prevalência, além de representar um alto custo em assistência hospitalar. Ao estudar o tema, deve-se levar em consideração as variações geográficas, culturais e próprias da amostra a ser analisada. Objetivo: O presente trabalho teve por objetivo realizar um levantamento epidemiológico, dos pacientes com fraturas faciais atendidos em um hospital terciário. Métodos: Foram revisados retrospectivamente os dados dos prontuários eletrônicos de pacientes atendidos entre maio de 2013 e abril de 2018 no Hospital Cristo Redentor de Porto Alegre/RS. Resultados: Foram incluídos 1.230 pacientes, com um total de 2.241 fraturas faciais, sendo a mandíbula o sítio mais acometido (45,65%), seguida pelo complexo orbitozigomaticomaxilar (31,28%). O fator etiológico mais observado foram os acidentes automobilísticos (32,2%), e o método de tratamento utilizado com maior frequência foi a redução aberta com fixação interna (RAFI), sendo aplicada em 377 pacientes (30,65%). Conclusões: Os resultados dessa análise associados à di- vulgação contínua de dados atualizados que reflitam as realidades locais são determinantes na melhor compreensão desses eventos e na orientação de políticas de saúde públicas focadas em controle, prevenção e recuperação desses pacientes.
