Cleft palate repair is the most important component of cleft surgery, not only in that it determines the outcome as far as speech and communication are concerned, but also in that it potentially has the greatest impact on maxillary growth and the dental arch relationship. Sommerlad technique has been described as a more physiological approach, aiming to restore the anatomy of the velum. This technique, often described as radical intravelar veloplasty, has the following distinctive components: a radical retroposition of velar musculature (m. levator veli palatini, m. palatoglossus, and m. palatopharyngeus), combined with minimal dissection of the hard palate, a tensor tenotomy, and the repair of the m. levator sling

| Repair of cleft palate with intravelar veloplasty (IVVP) | Procedure | A triangular flap is designed comprising new epithelial tissue which will be turned over to help close the nasal mucosa. Using a single hook, the oral mucosa and gland layer is separated from the muscle layer. Dissection of the greater palatine nerve-vessel bundle. The anterior palatal flap is raised by a curved elevator. The closure of the nasal mucosa and muscle is completed. Dissection of Velo Palatine Levator begins from the posterior rim of muscle and 5 mm from the midline. |

| change in tongue motion assessment | Observing the range of tongue motion using videofluoroscopy | Baseline, immediately after procedure |
| change in lips motion assessment | Observing the range of lips motion using videofluoroscopy | Baseline, immediately after procedure |
| change in nasal airflow | Using Nasometer II model 6450 to assess the ratio of oral airflow to nasal airflow. | Baseline, immediately after procedure |
