**7.7 Palatal flap**

A festoon flap is performed at the gingival margins on the palatal side. This flap is used in periapical surgery of the palatal roots of the maxillary molars. Palatal releasing incisions are not necessary. If any such incisions are made, they should be performed between the canine and premolar, representing the vascularization limit between the nasopalatine artery and the anterior palatine artery, or distal to the second molar behind the emergence point of the anterior palatine artery [24].

Advantage

• Useful in cases in which the palatal roots of molars or lateral incisors require exposure
