Alcune varianti anatomiche del complesso ostiomeatale (COM) possono contribuire al blocco del meato medio ed essere responsabili di sindromi cefalalgiche associate o meno a sinusopatia.
Allo scopo di stabilire l'incidenza delle varianti anatomiche del COM in pazienti sottoposti a tomografia computerizzata (TC) del massiccio facciale per cefalea di presunta origine sinusale, abbiamo riesaminato 316 studi TC effettuati in oltre un anno di attività, escludendo la patologia traumatica e neoplastica, le poliposi massive, i papillomi invertiti, gli esiti di pregressi interventi chirurgici.
I pazienti con sinusopatia evidente alla TC non hanno complessivamente mostrato una incidenza significativamente superiore di anomalie del COM. Tuttavia alcune di esse, come la pneumatizzazione della lamella verticale, la curvatura paradossa del cornetto medio, la presenza di cellule di Haller e la pneumatizzazione del processo uncinato, sono risultate più comuni nei pazienti affetti da malattia mucosa.
I nostri risultati confermano che le anomalie del COM, pur non essendo l'unico fattore patogenetico, possono essere considerate predisponenti alla malattia sinusale.
