Abstract:
OBJECTIVETo establish a method for assist design of the posterior pharyngeal flap (PPF).
METHODSThe width, length of velopharyngeal space in repose and phonation of "i" in 26 cases with VPI were measured with CT. The width and length of PPF needed, the location of the pedicle and the contact position with the soft palate were analyzed.
RESULTSThe width of velopharyngeal space in repose ranged from 15.10 to 37.25 mm, with the average of 27.01 mm, the length was 12.54 to 30.39 mm, with the average of 22.10 mm. The width in phonation of "i" was 9.11 to 34.06 mm, with the average of 17.69 mm, the position of the pedicle wasall located at the level of the first cervical vertebra or above and the contact area of the flap with the soft palate was in the middle posterior 1/3 mostly.
CONCLUSIONAs a method to quantitatively evaluate velopharyngeal function, CT can assist in design for the PPF.
