Impact of a Modified Restoration of Tensor Veli Palatini on Hearing and Middle Ear Function in Cleft Palate Children-a Retrospective Study.

Abstract

Many children with cleft palate also exhibit hearing loss and middle ear dysfunction, which could last for years. There are still arguments on how to treat this problem. This study aimed to evaluate the impact of a modified restoration of tensor veli palatine (TVP) on hearing and middle ear function in the cleft palate children. This retrospective study was completed using records of the cleft palate children who received surgery in Peking Union Medical College Hospital from May 2013 to December 2020. They were divided into 2 groups: Group 1: children who received cleft palate surgery without specific restoration of TVP; Group 2: children who received palate surgery with a specific TVP restoration technique. Perioperative information was collected. The conductive auditory brainstem response and the 226-Hz tympanometry before and after the cleft surgery were compared intragroup and intergroup. Totally 42 children were included in this study, 21 children in each group. There were no significant differences considering clinical characteristics between the 2 groups. The modified TVP restoration didn't increase operation time or complication compared with no TVP restoration. Statistically, neither the auditory brainstem response air conduction hearing thresholds nor the 226-Hz tympanometry results had significant differences between the 2 groups after the surgery. This modified restoration of TVP was not time-consuming and did not increase complications. The beneficial effect of the modified TVP restoration on the hearing or the middle ear function of cleft palate children was uncertain around 6 months after surgery compared with no restoration.
