Can you please tell me what this means in English so I can better understand what it means before they send me in for surgery in a couple of weeks? INDICATION: chronic sinusitis . Sleep apnea. COMPARISON: CT neck October 7, 2013. ENCOUNTER: Not applicable FINDINGS: There is minimal biconvex deviation of the nasal septum without osseous spur. There are no nasal polyps. A prominent concha bullosa formation is noted in the right middle nasal turbinate with paradoxical configuration of the smaller left middle nasal turbinate. There is narrowing of both the middle meatus and infundibula on the right as well as mild narrowing of the infundibulum on the left. Haller cell formation contributes to narrowing of the left infundibula. There is a prominent well-circumscribed mass which occupies approximately two thirds of the volume of the right maxillary sinus. This likely represents a retention cyst and is not significantly altered in appearance compared to the CT examination of October 7, 2013. A similar finding is noted at the base of the left maxillary sinus. This is considerably smaller than noted on the prior CT examination of October 7, 2013. The frontal sinuses and frontal recesses are well-aerated as are the ethmoid sinuses. The sphenoid sinuses and sphenoethmoidal recesses are also aerated. Negative for bone destruction skull base. The orbits demonstrate a normal appearance. The mastoid air cells and middle ears are well-aerated. There is prominent soft tissue in the nasopharynx likely representing hypertrophic adenoidal tissue. IMPRESSION: 1. Minimal nasal septal deviation. There are no nasal polyps. There is narrowing of the ostiomeatal complex on the right and a lesser degree narrowing of the infundibula of the left ostiomeatal complex. 2. Mass lesions present in the maxillary sinuses bilaterally. There are most consistent with retention cysts. That on the right side is stable compared to the prior CT examination of October 7, 2013 while the left sided lesion is considerably decreased in volume compared to the prior study.
