Primary Palatoplasty With Intravelar Veloplasty Using Acellular Dermal Matrix Interpositional Graft
- The aim of this study was to analyze the effect of acellular dermal matrix (ADM) on fistula formation after primary palatoplasty using intravelar veloplasty for levator veli palatini muscle repair.
This single-center retrospective study included patients who underwent primary palatoplasty with intravelar veloplasty for reorientation of the levator veli palatini muscles between April 2014 and March 2018. In the control group (group A) conventional intravelar veloplasty was performed, while in the ADM group (group B) intravelar veloplasty using ADM was performed. The study sample was composed of 162 patients, 81 in each of the 2 groups (A and B). In group B, securely dissected muscles were overlapped, and a pentagon-shaped ADM (AlloDerm, LifeCell Corp., Branchburg, NJ) of 1.6 mm mean thickness, 11.3 mm mean width, and 14.4 mm mean length was designed, and placed under the repaired levator muscle sling. The outcome variable was the occurrence of oronasal fistula within the first 6 months after surgery.
Postoperative fistula formation was reported in 6 patients in group A (7.4%) and in 5 patients in group B (6.2%). There was no statistically significant difference between the 2 groups (P = 0.755). There were 7 cases of ADM exposure and 2 cases of wound dehiscence in group B.
The results of this study demonstrated that ADM use did not have any disadvantage with respect to oronasal fistula complications after intravelar veloplasty for levator veli palatini muscle repair.
