While there was a significant increase in the oropharynx and hypopharynx values in all groups, the increase of nasopharynx values from T1 to T2 was only insignificant in the control group.
(1,4,6) Some of those cases had regional recurrences after surgery and chemotherapy, but to the best of our knowledge, this is the first case with relapse involving the nasopharynx.
A low-attenuation, nonenhancing mass was also present, extending from the right maxillary sinus through an enlarged ostium and then projecting posteriorly through the right nasal cavity into posterior nasopharynx. Its diameter in the nasopharynx was approximately 3 cm.
Under guidance of real-time ultrasound, an abnormally heterogeneous low echo next to the right sidewall of the nasopharynx was detected, and the puncture needle was then placed into the target lesion [Figure 1]h and [Figure 1]i.
We have called this nasal spirometry since airflow is through the nasopharynx and nose.
Next were rhinosinusitis 108 (28.19%), hypertension 48 (12.53%), trauma 35 (9.13%), DNS with spur 14 (3.65%), fibroangioma 13 (3.39%), foreign body nose 9 (2.34%), juvenile nasopharyngeal fibroma 3 (0.78%), carcinoma nasopharynx 3 (0.78%), rhinosporidiosis 2 (0.52%), hereditary telangiectasia 2 (0.52%) in descending order.
Contrast-enhanced computed tomogram showed heterogeneously enhancing soft tissue mass lesion in the right posterolateral wall of nasopharynx measuring 6 x 3.7 x 4 cm with erosion of the adjacent bone with involvement of the pterygoid muscles (Figure 2).
The nasopharynx is an uncommon lodgment site for foreign bodies.
A: Axial CT image without contrast shows a pedunculated soft-tissue attenuation mass arising from the posterior nasal septum that protrudes into the nasopharynx. B: Axial CT image with contrast shows avid enhancement within the mass.
Gilsdorf, MD, and his group (1) at the University of Michigan, Ann Arbor, recently showed that, among the various high-molecular-weight molecules (HMW) produced by 170 ntHi from three different geographically diverse countries, one variant in particular (HMW-A) was more likely to be found in strains producing AOM than strains simply colonizing the nasopharynx. The protein product of this gene allows better adherence to respiratory epithelia.
The pharyngeal bursa (PB) is a recess lined with respiratory epithelium along the midline posterior superior wall of the nasopharynx between the longus capitis muscles.
