mucosal cysts of the minor salivary glands are oral soft - tissue lesions that arise as dome - shaped swellings seen commonly on mucosal surface of lower lips and buccal mucosa .
many modalities of treatment for mucosal cysts exist , including excision and suturing , deroofing , marsupialisation , radiosurgery and cryotherapy .
four patients of age between 9 and 25 years were treated between june and december 2011 . a male patient aged 9 years had a dome - shaped smooth , tense , bluish cyst of size 5 mm on the lower lip .
the second patient was a female aged 24 years , with a mucosal cyst of 4 mm on the buccal mucosa .
the third patient , a female aged 21 years , had a lesion of size 6 mm in the buccal mucosa .
the fourth patient was a male patient aged 25 years , who had a recurrent mucosal cyst [ figure 1 ] in the buccal mucosa which was treated 10 months back by electrocautery .
no local anaesthesia was used . under aseptic precautions , a very small quantity of 88% phenol was injected into the cyst cavity using insulin syringes [ figure 2 ] .
patients were given analgesics post procedure for 1 day . injection of 0.1cc of 88% phenol into cyst the procedure was uneventful in all the cases .
two of the patients complained of slight burning sensation during the procedure , which subsided within a few minutes .
this was followed by complete healing with slight scarring within 2 weeks [ figure 3 ] .
although many other modalities of treatment of mucosal cysts exist , intralesional 88% phenol presents a simple and effective way of treating them .
the advantage is that there is no intraoperative or postoperative bleeding , there are minimal surgical defects and there is minimal scarring .
hence , intralesional injection of 88% phenol presents an easy and effective way for treatment of mucosal cysts .
 mucous cysts are one of the common cystic lesions of minor salivary glands seen mostly on mucous surface of lower lip and buccal mucosa 
 . many modalities of treatment for mucosal cysts exist including excision and suturing , deroofing , marsupialization , radiosurgery and cryotherapy . 
 we have used 88% phenol as a mode of treatment of mucosal cysts .
