Comparison of two different labial salivary gland biopsy incision techniques: a randomized clinical trial

Med Oral Patol Oral Cir Bucal. 2013 Nov 1;18(6):e851-5. doi: 10.4317/medoral.19033.

Abstract

Objective: To compare the reliability of two different labial salivary gland biopsy (LSGB) incision techniques (vertical versus horizontal incision techniques) and to report the related complications and discomfort.

Study design: 163 patients who underwent LSGB were included in this study. Patients were randomly divided as vertical incision group (n=81) and horizontal incision group (n=82). Demographic and clinical information of each patient were recorded. A questionnaire was prepared and applied together with Visual Analog Scale (VAS) on the subjects verbally at the 7th day, postoperatively. Intraoperative, short- term and delayed complications were evaluated.

Results: The mean age of patients (117 female, 46 male) was 47.3 years (range 19-79 years). Vertical incision technique was associated with less pain (p<0.001), less swelling (p<0.05), less scar formation (p<0.05) and less difficulty in eating (p<0.05) when compared with horizontal incision technique. No statistically significant differences were observed between the 2 groups in terms of hematoma, parasthesia and speech difficulty (p>0.05). Additionally, two subjects in the horizontal incision group revealed permanent paresthesia during the follow-up period of two years.

Conclusion: This prospective study demonstrated that the subjects in the vertical incision group had less complication rates and discomfort after labial salivary gland procedure than those in the horizontal incision group.
