IntroductionMucus extravasation cyst or mucocele is commonly occurring lesion in oral mucosa containing mucin that may result from trauma to minor salivary glands. It is a well?defined tissue swelling composed of pooled mucus that escaped into the connective tissue from a severed excretory duct. The incidence rate is high and it is the second most commonly occurring lesion after irritational fibroma in the oral cavity, prevalent in second decade of life with no sex predilection. Commonly involving lower lip, followed by tongue, buccal mucosa, palate, and retromolar area. Clinically mucocele is few millimeters to centimeters in diameter, painless, fluctuant, and imparts transparent to bluish hue. Etiology for mucocele was well?described by Yamasoba et al., in 1990 which includes trauma and obstruction of salivary duct in minor salivary glands. Since mucocele has high recurrence rate, various treatment approaches have been tried like surgical, cryosurgical, intralesional corticosteroids, marsupialization, micromarsupialization, and lasers.
Different kinds of lasers are available with varying wavelength and absorption coefficient. Lasers causes less trauma, improved healing, and faster recovery time when compared with conventional methods. Diode lasers especially that of wavelength 810 nm have high affinity for melanin and haemoglobin. This property enables it to precisely cut, coagulate, ablate, or vaporize the target soft tissue. Diode lasers are easy to move and handle since they do not have water or airlines.

…oedema, irritation and delayed healing. Vaporization with argon and Nd:YAG lasers offered good alternative but biopsy sample could not be obtained. CO2 laser often results in scarring of the operated site.
A diode laser was used in these cases as it offers the advantage of providing bloodless field, rapid healing and being easy to operate. Light of wavelength of 810 nm is intensely absorbed by oxygenated haemoglobin, resulting in elevation of temperature at operative site, promoting coagulation and carbonization of soft tissues, with minimum discomfort and scarring. Another important advantage is that it causes no alteration in microanatomy of biopsy specimen. Excessive heat may be prevented by intermittent irrigation with normal saline. No sutures or surgical pack is required. As seen in our cases, usually no scar formation occurs at the operated site.
