title: Comparison of two different labial salivary gland biopsy incision techniques: a randomized clinical trial.
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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
