A retrospective study of ranula in two centres in Malaysia

Excision of sublingual gland as treatment for ranulas in pediatric patients

OBJECTIVE

The aim of this case study is to demonstrate that post-operative complication rates of sublingual gland excision for treatment of ranulas are equal to or less than alternative methods with a lower recurrence rate than other surgical methods.

METHODS

This was a retrospective review of pediatric patients from 2004 to 2015 at Children's Hospitals and Clinics of Minnesota. Sixteen ranulas and 6 plunging ranulas were treated via sublingual gland excision during this time frame. Data examined included age, gender, scans of the lesion, location and size of lesion, surgical procedures, complications, and recurrence.

RESULTS

There were 22 patients who met criteria. Only one patient had recurrence of the lesion (4.5%). One patient reported lateral tongue numbness post-operatively, and one patient had a hypoglossal nerve injury, with tongue deviation upon exam. Both of these complications were temporary and resolved within months of the procedure.

CONCLUSION

Although sublingual gland excision is a definitive treatment for ranulas, many surgeons still utilize other methods such as marsupialization, drainage of the cyst, or excision of ranula alone as the primary method of treatment due to concerns about complications. This retrospective study demonstrates that excision of the sublingual gland is both a safe and effective method of treatment for ranulas.

A Rare Cause of Acute Respiratory Distress: Cervical Ranula

Plunging or cervical ranula is a mucus extravasation pseudocyst arising from the sublingual gland that is located below the mylohyoid muscle. Clinically, if large enough, cervical ranulas can affect swallowing, speech, chewing, and even breathing. The acute presentation of ranulas, which are clinically known as slow-growing, painless masses, is rare. In this study, we present a case of cervical ranula that grew in a short period of 3 days and resulted in respiratory distress and that was operated in our clinic.
