Introduction. Antrochoanal polyp is a benign tumor of the maxillary sinus mucosa passing through the sinus ostium into the nasal cavity. Nasal obstruction is the most common symptom in all patients. Case Report. The authors present a case of a 28-year old female who was admitted to hospital with breathing difficulty, unilateral nasal secretion, headache and deformity of the nasal pyramid. Computerized tomography examination of the nose and paranasal sinuses indicated a possibility of giant antrochoanal polyp. The antrochoanal polyp was extirpated completely using forceps, under general endotracheal anesthesia. The length of the giant polyp was 16 cm. A follow-up examination of the nose and the right maxillary sinus was performed using a rigid endoscope, but no remains of the polyp were found. Conclusion. The authors believe that this is probably the first or a very rare published case of complete extirpation of a giant antrochoanal polyp of this size.
