Study of ethmoidal canals in anatomical specimens under endoscopic view and histological analysis

Introdução: O advento do endoscópio possibilitou a difusão da via endonasal para diversos tipos de doenças. O estudo dos canais etmoidais é importante para cirurgias dos seios paranasais e da base anterior do crânio. O objetivo desta pesquisa foi investigar os canais etmoidais, para avaliar a estrutura do canal, a presença de vasos, nervos, a localização e o estudo anatomopatológico. Material e método: Avaliaram-se 20 cadáveres (20 fossas nasais esquerdas e 20 fossas nasais direitas) com: 1- dissecção endoscópica da base anterior do crânio, exposição da periórbita medial e dura-máter; 2- localização dos canais etmoidais; 3- medida dos canais etmoidais em relação à parede anterior do seio esfenoidal e entre as artérias etmoidais; 4- remoção do conteúdo dos canais etmoidais para análise histológica. Resultados: A média do Canal Etmoidal Anterior Esquerdo (CEAE) em relação ao Canal Etmoidal Posterior Esquerdo (CEPE), foi 1,45 cm; CEPE-esfenoide (E) a média de 0,65 cm; Canal Etmoidal Anterior Direito (CEAD) em relação ao Canal Etmoidal Posterior Direito (CEPD) média de 1,41 cm; CEPD-E, média de 0,78 cm; CEAE quanto ao Canal Etmoidal Médio Esquerdo (CEME), média de 0,93 cm; e CEAD referente ao Canal Etmoidal Médio Direito (CEMD) obteve média de 1,00 cm. Conclusão: Identificaram-se 75% dos canais etmoidais anteriores esquerdos com vasos, 70% dos canais etmoidais posteriores esquerdos com vaso, 75% dos canais etmoidais médios esquerdos com vasos, 85% dos canais etmoidais anteriores direitos com vasos, 64,5% dos canais etmoidais posteriores direitos com vaso e 50% dos canais etmoidais médios direitos com vasoIntroduction: With the advent of the endoscope, it has become possible to utilize the endonasal approach for a variety of types of diseases. Study of the ethmoid canals is important for surgeries of the paranasal sinuses and to the anterior skull base. The objective of this research is to investigate the ethmoidal canals, to evaluate the structure of the canal, presence of vessels, nerves, location of the canal and anatomopathological study. Materials and methods: 20 cadavers (20 left nasal cavities and 20 right nasal cavities) were evaluated with: 1- endoscopic dissection of the anterior skull base, exposure of the medial periorbita and dura mater; 2- location of the ethmoidal canals; 3- measurement of the ethmoid canals in relation to the anterior wall of the sphenoid sinus and between the ethmoidal arteries; 4- removal of the content of the ethmoidal canals for histological analysis. Results: The average of the Left Anterior Ethmoidal Canal (CEAE) in relation to the Left Posterior Ethmoidal Canal (CEPE) was 1.45 cm; CEPE-sphenoid (E) average of 0.65cm; Right Anterior Ethmoidal Canal (RDC) in relation to the Right Posterior Ethmoidal Canal (RCEP) average of 1.41 cm; average of CEPD-E of 0.78 cm; CEAE regarding the Left Middle Ethmoidal Canal (CEME) average of 0.93 cm; and CEAD referring to the Right Middle Ethmoidal Canal (CEMD) obtained an average of 1.00 cm. Conclusion: 75% of the left anterior ethmoidal canals contained vessels, 70% of the left posterior ethmoid canals contained vessels, 75% of the left middle ethmoidal canals contained vessels, 85% of the right anterior ethmoid canals contained vessels, 64.5 % of the right posterior ethmoid canals contained one vessel and 50% of the right middle ethmoidal canals contained one vesse

Endoscopic Study of Ethmoidal Canals in Cadavers, Including a Histological Analysis of Their Contents

Transnasal approach to the orbital apex and cavernous sinus

OBJECTIVES: The aim of this study was to provide the anatomic rationale for a transnasal approach to the orbital apex and cavernous sinus, and to evaluate its applicability and efficiency. METHODS: One hundred patients with lesions of the orbital apex, cavernous sinus, optic nerve, clivus, parapharyngeal space, infratemporal fossa, or pterygopalatine fossa were reviewed over a 10-year period. All patients underwent an endoscopic transnasal approach to the orbital apex and cavernous sinus. The surgical technique required a standard endoscopic sinus surgery set. The possible complications were recorded and classified as intraoperative or postoperative. RESULTS: There were complications in 8 cases: 4 intraoperative and 4 postoperative. The intraoperative complications included rupture of the internal carotid artery in 1 patient and cerebrospinal fluid leak in 3 patients. All intraoperative complications were resolved during surgery. The postoperative complications were transitory eyelid ptosis in 2 patients (resolved in 6 months) and transitory diplopia with immediate deficit of the medial rectus muscle in 2 patients (completely resolved in 1 month). CONCLUSIONS: With the use of this technique, the surgeon can precisely identify the position of the surgical instrument without losing his or her way, thereby significantly reducing the rate of complications

Rhino facial zygomycosis: case report

<p></p><p>Zygomycosis is an invasive disease that affects both immunocompetent and immunocompromised, depending on the type of strain. This disease diagnosis is clinical and histopathological, and its treatment is based on antifungal therapy and surgical cleaning. This paper reports a case of a boy with invasive zygomycosis rinofacial who final treatment was successful after underwent antifungal and surgical therapies.</p><p></p
