The Postoperative Speech Intelligibility Evaluation of Modified Z-Plasty Palatoplasty.

The aim of the present study is to test the feasibility of modified Z-plasty palatoplasty for cleft palate repair in surgeries and provide a new surgical method. Forty cleft palate patients were selected as participants and divided into 2 groups in random. Twenty patients in the experiment group were treated by modified Z-plasty palatoplasty while the other 20 patients in the control group by double opposing Z-plasty and Sommerlad palatoplasty. By evaluating and observing postoperative velopharyngeal movement, speech intelligibility, nasal leaking, analysis of CSL (Computer Structure Language) and X-ray velopharyngeal lateral radiographs, Modified Z-plasty palatoplasty achieved better results than traditional operation. Satisfactory linguistic effects on incomplete cleft palate can be observed after modified Z-plasty palatoplasty treatment. So this method may be used as a clinical choice.
