Lymphoid Hyperplasia of the Nasopharynx: A Study of One Hundred and Thirty-One Autopsy Specimens

Pathogenesis of Cysts and Crypts in the Nasopharynx

“…It is of special interest to note that hyperplasia of the nasopharyngeal tonsil is often seen in persons past 70 years of age. (Hollender and Szanto, 1945. ) The tonsillar crypts are not connected to secreting glands and therefore when obstructed should not result in the formation of retention cysts.…”

“…pouch was reported by Mills (1955). Since Rathke's pouch tumours are usually supra-sellar, Keohane (1958) was of the opinion that such a cyst is more likely to have arisen in remnants of Seessel's pouch. It is apparent from the foregoing, that embryological cysts in the nasopharynx are recognizable by their anatomical relationship since there are no distinguishing histological features to warrant diagnosis of branchial cysts.…”

Short-term Volumetric and Minimal Area Changes in the Pharyngeal Airway After Use of a Fixed Functional Appliance: A Three-dimensional CBCT Investigation

“…Scammon's growth curve demonstrates that the lymphoid tissue grows to 200% of normal adult size around 10.45 years. 14 All subjects included in the current study were of a similar age range, with the mean age being 14.8 years with CVMI stage C4. This indicates relative stability of the airway and remaining growth potential for a fixed functional appliance to affect the advancement of the mandible.…”
