Twenty-four of these patients underwent repeated polysomnographic studies with the nasopharyngeal tube in place. They had a 62.3 percent decrease in apnea index and a 39.2 percent decrease in disordered breathing events/h. The nasopharyngeal tube was successful in 16 of the 24 patients (66.7 percent efficacy), and overall patient tolerance of the tube was 44.2 percent. The nasopharyngeal tube failures had a higher apnea + hypopnea index, lower SaO2 nadir, and a higher PaCO2 than the nasopharyngeal tube successes. They were also heavier than the successful patients. The nasopharyngeal tube is a useful alternative treatment for patients with OSA syndrome and may be used as an immediate therapeutic modality while the patient loses weight or as an alternative for those patients who fail or cannot tolerate nasal continuous positive airway pressure.

Based on this, the aim of this study was to evaluate the longevity of prosthetic rehabilitation treatment with implant-supported overdenture (IOD) and implant-supported fixed denture (IFD) in cleft lip and palate patients in a period of 22 years. The medical records of 72 patients were analyzed (29 males and 43 females), and the survival rate of the implants was evaluated. Moreover, the prostheses' time of use and the reason for the changing of these were also evaluated. Four-hundred-seventeen implants were installed, and 370 implants survive today. The mean survival time of the implants was 7.6 years. Regarding the 97 prostheses made, the time of average use was 3.28 for the IFDs and 3.92 for IODs. The reasons for the replacements of the prostheses were mainly: fracture of the acrylic base (29.6%) and loss of vertical dimension of occlusion (VDO) (18.5%) in the IFDs. Moreover, in IODs, these were accounted for the loss ...
