Manejo endoscópico endonasal de coristoma ocular delápex orbitario y fosa media: reporte de caso

Introduction: Endoscopic endonasal approaches are a tool for complex orbit and skull base lesions, offering better visualization and lower morbidity than open te­chniques. Clinical case: A 14-year-old female with left orbital apex compressive syndrome. Imaging suggestive of schwannoma. Complete resection was performed via an extended endoscopic endonasal transpterygoid approach. Definitive histo­pathological study revealed a cystic respiratory choristoma. Discussion: Orbital choristomas are extremely rare. For lesions in the orbital apex with extension to the middle fossa, the endonasal approach offers advantages: excellent visualization, no external incisions, and less neural manipulation. This is the second reported case ma­naged with this technique. Conclusions: Orbital apex choristoma is a rare entity. The endoscopic endonasal approach is an effective and safe surgical option in selected cases, requiring an expert multidisciplinary team to optimize results.
