Endoscopic prelacrimal recess approach is a promising technique for treating various maxillary sinus diseases because it allows for adequate visualization and wide access to the entire maxillary sinus. However, the incidence of absent prelacrimal recess (PLR) has ranged from 7% to 17.5%, implying that there is a limitation for the application of EPLA in this population. Here, a male patient with concomitant Krouse T2 maxillary inverted papilloma and mycetoma presenting with unilateral nasal obstruction and blood-tinged secretion is described. The presurgical computed tomography showed no recess. By dislocating the nasolacrimal duct from the bony canal and removing the medial maxillary wall sufficiently to extend the surgical corridor; and by preserving the inferior turbinate, nasal mucosa, and nasolacrimal duct, the patient did not experience any postoperative complications. In conclusion, our modified technique may be an effective and safe strategy for treating maxillary sinus disease without prelacrimal recess.Le texte complet de cet article est disponible en PDF.
