Tensor Veli Palatini Preservation, Transection, and Transection with Tensor Tenopexy during Cleft Palate Repair and Its Effects on Eustachian Tube Function

Background: During cleft palate repair, levator sling palatoplasty with tensor veli palatini tendon transection significantly improves speech results. However, the procedure may pose a risk to eustachian tube function. This study assesses the impact of three types of palatoplasty techniques on eustachian tube function: no tensor transection, tensor transection alone, and a new addition to the palatoplasty technique, tensor tenopexy. Methods: A retrospective review was conducted of all patients undergoing cleft palate repair at two institutions between 1997 and 2001. Three cleft palate repair groups were studied: no tensor transection (n = 64), tensor transection alone (n = 31), and tensor tenopexy (n = 52). The percentages of patients requiring myringotomy tubes at each year of age were compared among the three groups. Results: By 7 years of age, there was a significantly decreased need for myringotomy tubes in patients who underwent no tensor transection compared with patients who underwent tensor transection alone (38 percent versus 61 percent, respectively; p = 0.05), as well as for patients who underwent tensor tenopexy compared with patients who underwent tensor veli palatini tendon transection (23 percent versus 61 percent, respectively; p < 0.001). Also, by the age of 7, there was a trend toward a decreased need for myringotomy tubes in patients who underwent tensor tenopexy compared with patients who underwent no tensor transection (23 percent versus 38 percent, respectively; p = 0.11). Conclusions: No tensor transection and tensor tenopexy significantly decrease the need for myringotomy tubes compared with tensor transection alone. There is a small decrease in the need for myringotomy tubes when comparing tensor tenopexy with no tensor transection. (Plast. Reconstr. Surg. 125: 282, 2010.)
