Abstract
Purpose: to verify the occurrence of posterior or submucosal lingual frenulum and evaluate the efficiency of a special maneuver for its visual inspection.
Methods: an experimental study including 1,715 healthy infants, in which prematurity, perinatal complications, craniofacial anomalies neurological disorders, and visible genetic syndromes were the exclusion criteria. A clinical examination was performed by means of a maneuver that consisted in rising the lateral margins of the tongue to visualize the anatomical characteristics of the lingual frenulum. In some of the infants, a special maneuver was performed to assist visualization of posterior lingual frenulum, since its visualization was not possible. The maneuver consisted in two simultaneous actions: elevating and pushing the tongue back.
Results: 558 infants (32.54%), out of the 1,715 had posterior frenulum, which required the special maneuver that consisted in both elevating and pushing the tongue back, simultaneously.
Conclusion: the occurrence of posterior lingual frenulum was high and the special maneuver consisted in elevating and pushing the tongue back proved to be efficient to visualize the posterior lingual frenulum.

Resumo
Objetivos: verificar a ocorrência do frênulo lingual posterior ou submucoso, bem como, avaliar a eficiência de uma manobra que possibilita sua visualização.
Métodos: estudo experimental realizado com 1715 lactentes saudáveis, sendo considerados como critérios de exclusão a prematuridade, as complicações perinatais, a presença de anomalias craniofaciais, as doenças neurológicas e as síndromes genéticas. Exame clínico realizado por meio da manobra de elevação da língua para observar as características anatômicas do frênulo lingual. Nos lactentes cuja visualização do frênulo não foi possível apenas com a referida manobra, pois o mesmo se encontrava recoberto por uma cortina de mucosa, foi utilizada uma manobra simultânea de elevação e posteriorização da língua.
Resultados: dos 1715 lactentes avaliados, em 558 não foi possível visualizar o frênulo lingual somente por meio da manobra de elevação, pois os lactentes apresentaram frênulo posterior ou submucoso, havendo necessidade de realizar uma manobra simultânea de posteriorização da língua para visualização das características anatômicas.
Conclusão: a ocorrência do frênulo posterior ou submucoso foi alta, sendo que a manobra de elevação e posteriorização da língua se mostrou eficiente para evidenciar o frênulo recoberto por cortina de mucosa.
