Abstract

Mnoge studije pokazale su povezanost između hiperplazije adenoidnih vegetacija i nastanka ortodontskih anomalija. Zbog svog smještaja na gornjoj i stražnoj stijenci epifarinksa, hipertrofična ždrijelna tonzila uzrokuje parcijalnu opstrukciju nosnog i dovodi do razvoja orofaringealnog disanja. Promjena načina disanja utječe na obrazac rasta čeljusti i položaj zuba. Kako bi se disalo na usta, neophodno je zabacivanje glave unatrag, spuštanje mandibule i jezika. Ako ovakvo stanje perzistira, povećava se prednja visina lica, stražnji zubi preizrastaju, mandibula rotira prema dolje i natrag, otvarajući pritom zagriz i povećavajući pregriz, dok povećan pritisak rastegnutih obraza uzrokuje suženje maksilarnog zubnog luka. Lice je djeteta izduženo, uvučenih očiju s nagalašenim podočnjacima, usnice su suhe, ispucale i inkompetentne, a gingiva upaljena i hiperplastična. Takav karakterističan izgled lica nazivamo facies adenoidea. Hipertrofični adenoidi kod djece odstranjuju se postupkom adenoidektomije, koji je ujedno i najčešći operacijski zahvat te dobne skupine, te se na taj način smanjuje intenzitet prisutnih ortodontskih anomalija i uspostavlja se normalno disanje na nos. Perzistentne ortodotske anomalije zahtijevaju uporabu različitih ortodontskih pomagala, ovisno o kojoj je anomaliji riječ.

Abstract (english)

A lot of study cases have shown connection between adenoid hyperplasia and orthodontic anomalies. Due to its placement in epipharynx, adenoid hyperplasia causes obstruction of nasal breathing and provides mouth-breathing, which leads to growth form change of maxilla and mandibula, the same as the teeth malposition. During mouth-breathing, the head needs to be posteriorly reclined, and mandibula and the tongue lowered. If this condition persists, frontal facial height will increase, mandibula rotates downwards, the lateral segment teeth are erupting, which results in anterior open bite and greater overjet, while cheek pressure causes reduced transversal maxillary growth. Face appearance also changes. It becomes elongated, eyes are retracted with expressed eye bags, lips are incompetent, dry and, cracked, and gingiva inflamed and hyperplastic. This characteristic face shape is called facies adenoidea. Hyperplastic adenoid removal is indicated. Removal procedure is called adenoidectomy, and it presents the most often surgical procedure at that age. That way intensity of orthodontic anomalies is decreased and nasal breathing is established again. Persistent orthodontic anomalies need to be treated with different orthodontic supplies, which differ due to the type of orthodontic anomalies.
