  • Title: Anatomic correlates of normal and diseased adenoids in children.
    Author: Brodsky L, Koch RJ.
    Journal: Laryngoscope; 1992 Nov; 102(11):1268-74. PubMed ID: 1405989.
    Abstract:
    In order to better understand the pathogenesis and sequelae of obstructive adenoid hyperplasia in children, the anatomic relationships of the adenoids to the hard and soft palates, oropharynx, and nasopharynx were studied in vivo in 94 children. Direct, intraoperative palatal, nasopharyngeal, and oropharyngeal measurements were performed in 19 children with normal, nondiseased adenoids (controls [C]) and compared to 75 children undergoing adenoidectomy for obstructive adenoid hyperplasia (OAH) (n = 44) or chronic adenoid infection (CAI) (n = 31). As expected, the weight and volume of the adenoids removed were significantly greater in the OAH vs. CAI group (P < .001). Before adenoidectomy, the volume of the nasopharynx was significantly smaller in the OAH group; however, nasopharyngeal volumes after adenoidectomy were quite similar in all three groups and ranged from 5.4 to 6.2 cc. Only the change in the volume of the nasopharynx after adenoidectomy for obstruction was significant (2.5 +/- 1.2 cc, P < .01). Differences in oropharyngeal and palatal dimensions were not associated with longstanding obstruction from adenoid hyperplasia. These data indicate that the nasal obstruction from adenoid hyperplasia is due to an absolute increase in adenoid size rather than a relatively smaller nasopharynx. Differences in palatal and oropharyngeal dimensions usually described and attributed to longstanding nasal obstruction could not be demonstrated in this study.
