“…The adenoids are lymphatic tissue in the posteior-superior wall of the nasopharynx and they are typically prominent in children, gradually undergo atrophy after puberty (1)(2)(3)(4). It has been thought that most individuals have lost their adenoidal tissue by 30 years of age (3).…”

“…The adenoids, also called as nasopharyngeal tonsils, are lymphoid tissue located in the posterior superior wall of the nasopharynx (1)(2)(3)(4). They are physiologically prominent during early childhood and gradually undergo atrophy after 16 years (2)(3)(4). However, adenoids that are because of benign lymphoid hypertrophy may persist due to chronic inflammation or re-proliferation of regressed adenoidal tissue in response to irritants or infections (5).…”

Adenoids, also called nasopharyngeal tonsils, are lymphoid tissues located in the posterior-superior wall of the nasopharynx. Adenoids are prominent in early childhood, and atrophy occurs after age 16. However, regressive adenoidal tissue may show re-proliferation in response to infection or irritants. This makes discrimination between nasopharyngeal carcinoma and benign nasopharyngeal lymphoid tissue difficult. There are many articles about the adenoid-nasopharynx ratio (ANO) in children. However, there is no information on this rate in adulthood. Nasopharynx may be affected by environmental and personal factors such as posterior wall tissue thickness infections, seasonal allergic agents. For this reason, nasopharynx in association with seasons is intended to show normal data for posterior-superior wall thickness. Between August 01 2015 and July 31 2016, files of patients over 18 years of age with lateral cervical radiography were screened. The lateral cervical graphs of 720 patients, 60 patients per month, were evaluated. According to the seasonal variation of ANO ratio, there was no significant difference between summer and autumn, but there was a significant difference between all seasons. The highest rate was found in the winter, the lowest rate in the summer. These results indicate that adenoid tissue is thickened due to upper respiratory tract infections in winter and allergy in spring. Keywords: adenoid-nasopharynx ratio, adult, lateral cervical graphy, allergy. Öz: Nazofaringeal tonsil olarak da adlandırılan adenoidler nazofarinks posterior-süperior duvarda yerleşmiş lenfoid dokulardır. Adenoidler erken çocuklukta belirgindir, 16 yasından sonra atrofiye uğrarlar. Ancak enfeksiyon ya da irritanlara cevap olarak regrese adenoidal doku re-proliferasyon gösterebilir. Bu yüzden nazofaringeal karsinom ve bening nazofaringeal lenfoid doku arasında ayırım yapmak güçleşir. Çocuklardaki adenoid-nazofarenks oranı (ANO) hakkında birçok makale vardır. Ancak erişkinde bu oran hakkında bilgi yoktur. Nazofarenks posterior duvar doku kalınlığı infeksiyon, mevsimle ilişkili alerjik ajanlar gibi çevresel ve kişisel faktörlerden etkilenebilir. Bu nedenle, erişkinde mevsimle ilişkili olarak nazofarinks posterior-süperior duvar kalınlığı için normal verileri göstermeyi amaçladık. 01.Ağustos 2015-31 Temmuz 2016 tarihleri arasında lateral servikal grafi çekilmiş 18 yaş üstü hasta dosyaları tarandı. Her ay için 60 hasta olmak üzere 720 hastanın lateral-servikal grafileri değerlendirildi. Mevsimlere göre ANO oranı değişkenliğine bakıldığında Yaz-sonbahar arası anlamlı fark saptanmadı onun dışında tüm mevsimler arasında anlamlı fark bulundu. En yüksek oran kış mevsiminde,en düşük oran yaz mevsiminde tespit edildi. Bu sonuçlar bize kış mevsiminde üst solunum yolu enfeksiyonlarına bağlı, bahar aylarında ise allerjiye bağlı adenoid dokunun kalınlaştığını göstermektedir.

Tables of normal values are available for the measurement of four sagittal diameters (Roof, FM, C1 and C2) and areas of the soft tissue of the nasopharynx as seen in the lateral neck radiograph. The lateral neck radiographs of 100 nasopharyngeal carcinoma (NPC) cases as well as 100 normal controls of corresponding sex and age distribution are measured to ascertain the usefulness of the above measurement in the detection of NPC. Depending on the method of calculation, figures for positive results (sensitivity) may rise to as high as 85% but the specificity (i.e. probability of a correct diagnosis in a person without NPC) is at the same time lowered to 92%. The detection of NPC from any lateral neck radiograph, however, presents a different problem compared to the situation when a person clinically suspected of having NPC is referred for radiography. Many factors are involved in the former situation and it is to this situation that the predictive value (PV) of the scores has to be employed.
