Abstract
Oronasal fistulae are common complication following palatoraphy. There are several surgical procedures to repair oronasal fistulae. However, conventional oronasal fistulae closure technique is not always possible, especially when the surrounding tissue is replaced by fibrotic tissue due to previous palatoraphy. Tissue defects in oronasal fistulae should be replaced with tissues providing good vascularisation such as pedicle tongue flap. A case of pedicle tongue flap used to close oronasal fistulae was reported. Eleven-year-old girl, presented with oronasal fistulae and bilateral alveolar cleft after previous palatoraphy. The oronasal fistulae were closed with pedicled tongue flap. The healing was uneventful, and the division of the pedicle tongue flap was done three weeks later and closed primarily. There was no dehiscence of the wound and masticatory functions were recorded. Vascularised flap such as pedicle tongue flap is a preferred technique to close oronasal fistulae after palatoraphy.

Intra oral defects in the oral cavity can be caused by various factors, such as genetics, trauma, infection and iatrogenic (Sahoo et al, 2016)
Oronasal fistulae are abnormal communication between oral and nasal cavities occurring after surgical repair
The problems that arise are depending on the size of the oronasal fistulae
Summary
Intra oral defects in the oral cavity can be caused by various factors, such as genetics, trauma, infection and iatrogenic (Sahoo et al, 2016). Oronasal fistulae are abnormal communication between oral and nasal cavities occurring after surgical repair. After the first repair of cleft palate, oronasal fistulae develop in many of the patients. Oronasal fistulae closure can be accomplished with palatal flap, tongue flap
