Ameloblastoma (AM) in the maxillary sinus is rare. This benign entity shows locally invasive, destructive and aggressive behaviour and a high rate of recurrence. Therefore, the course of treatment is radical resection. We report the case of a 38-year-old man presenting with signs of recurrent sinusitis in the Ear, Nose and Throat Department. Transnasal flexible endoscopy revealed a cystic mass in the right inferior and middle nasal passage. CT scan showed an obliterated right maxillary sinus with a ballooning effect and pressure atrophy of the lateral sinus wall, without possible differentiation of the middle and low nasal turbinate. The patient was treated with transnasal functional sinus surgery; pathology stated AM. AM in the maxillary sinus is rare, locally destructive and therefore as a gold standard is resected radically to prevent recurrence. We demonstrate a conservative approach; explicitly, we combined a transvestibular and functional endoscopic sinus surgery resection of the AM to maintain function and reduce the possibility of postoperative impairments. Whether the strategy of treatment for AM is conservative, it nonetheless can result in a recurrence-free status. Nevertheless, inclusion into an oncological follow-up-programme with regularly performed MRI and CT is recommended.
