Resumo: | Objectives: morphometric description of anatomical structures adjacent to the lacrimal fossa and discussion of their surgical applicability.Study Design: Cross-sectional and retrospective.Methods: Computed tomography of paranasal sinuses in 100 patients.Results: Regarding the lacrimal fossa, the anterior limit of the middle turbinate head was anterior, adjacent and posterior in 45.5%, 10% and 44.5% of cases, respectively. The thickness of the ascending branch of the jaw in the area of the osteotomy was 5.2 mm. The lateral insertion of the process uncinate was pos lacrimal, lacrimal and pre lacrimal 52%, 33% and 15% of cases, respectively. The nasolacrimal duct and the lacrimal fossa measured 12.8 and 11 mm, respectively. The distance between naso lacrimal canal and the bone insertion of the middle turbinate was 4.8 mm. Approximately 60% of the lacrimal fossa is located above the middle turbinate insertion. The distance between the lacrimal fossa and the Agger Nasi was 6 mm.Conclusions: The values obtained are similar to those found in the literature. At least half of endoscopic dacryocystorhinostomy procedures (DCR En) require additional procedures. CT SPN is essential in the study of patients with indication for DCR En. |

A espessura do ramo ascendente da maxila, na região da osteotomia, foi de 5.2 mm. A inserção lateral da Apófise Unciforme foi pós lacrimal, lacrimal e pré lacrimal em 52%, 33% e 15% dos casos, respectivamente. O canal naso lacrimal e a fossa lacrimal mediram 8.12 e 11 mm, respectivamente. A distância entre o canal naso lacrimal e a inserção óssea do corneto médio foi de 4.8 mm. Aproximadamente 60% da fossa lacrimal localiza-se acima da inserção do corneto médio. A distância entre a fossa lacrimal e a Agger Nasi foi de 6 mm.Conclusões: Os valores obtidos são semelhantes aos encontrados na literatura. Durante as cirurgias de dacriocistorrinostomia endoscópica, pelo menos em metade, existe a necessidade de procedimentos adicionais.
