A retrospective 11-year study on lip lesions attended at an oral diagnostic service.

BACKGROUND

The objective of this study was to describe the upper and lower lip lesion occurrence in an oral diagnostic service.

MATERIAL AND

METHODS

Retrospective descriptive sectional study was performed. Clinical records were obtained from the archives of an Oral Diagnostic Service referral center between 2006 and 2016. Data such as gender, age, anatomical location, and diagnosis were collected and categorized. The collected data were submitted to a descriptive analysis and Pearson's chi-square test (p ≤ 0.05).

RESULTS

A total of 587 patient records of lip lesions were analyzed. Most lesions were diagnosed in female (52.1%) and adults (56.9%) patients in the lower lip (76.2%). Among all lip lesions, the reactive/inflammatory lesions (n = 238; 40.5%) and oral potentially malignant disorders (n = 164; 28%) were the most frequent group lesions. Mucocele (n = 147; 25%), actinic cheilitis (n = 136; 23.1%) and vascular lesions (n = 51; 8.7%) were the most frequent lesion in the sample. Actinic cheilitis was significant in relation to gender (p < 0.001), all three most frequent lesions were significant in concerning to age group and anatomical site.

CONCLUSIONS

Mucocele was the most common lower lip lesion in all age groups, followed by actinic cheilitis and vascular lesions, which mainly affected adults and the elderly.
