Paranasal sinus osteomas are the most common benign fibro-osseous lesions that occur in the paranasal sinuses, having potential serious complications. With a prevalence ratio of 2:1 towards males, in 95% of the cases, the osteomas are situated most commonly in the frontoethmoidal region. However, osteomas of the maxillary sinus account for less than 5% of cases. The management of symptomatic paranasal sinus osteomas is surgical and is decided based on tumor size and location, patient symptoms, and experience of the surgeon. The Caldwell–Luc procedure, lateral rhinotomy, or craniotomy as external standard procedures remain mandatory if endonasal endoscopic surgery fails. In most reported cases, large tumors are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumors is a huge challenge for the operator. We report on a 42-year-old male patient presenting with a giant calcified mass in the right maxillary sinus. In this case, an endonasal approach was the most appropriate management even with the large size of the tumor. No recurrence at 24 months follow-up was reported.
