[The impact of nasal obstruction on OSAHS].
OBJECTIVE
To evaluate the impact of nasal obstruction on OSAHS.


METHODS
One hundred and twenty cases of OSAHS with or without nasal obstruction were analyzed by Hypno PTT(PTT)and Mallampati score (MS); Acoustic rhinometry was measured in all 120 cases.


RESULTS
A significant correlation was found between the MS and the AHI measured during the sleep (r = 0.266, P < 0.01). The relative risk of OSAHS with a MS of III or IV in the whole group was 1.96, and 2.46 in cases with nasal obstruction.


CONCLUSIONS
A high MS represents a predisposing factor for OSAHS, especially in which associated with nasal obstruction.
