Twenty-seven out of eighty-five male patients who had undergone lip reconstruction using objective lip parameters, were studied to evaluate lip function after surgery. Firstly, objective lip parameters were assessed in 27 healthy volunteers; these were: intercommissural distance (ICD) at rest, in maximal lip contraction (purse), and maximal lateral retraction (wide grin), elesticity index (EI), soft-tissue gape (STG), oral access (OA), lower and upper sulcus depth (SD), lip sensitivity using two-point discrimination (2-PD). The patients were then subdivided into three groups according to the technique used: step technique, vermilionectomy wedge excision +/- 'W' plasty, Abbe flap, Bernard technique and excision. Statistical analysis was performed using two sample t-Student test. Each of the first three groups was compared to groups of normal volunteers matched for age, sex and number of individuals. The results showed a significant degree of microstomial normal lip sensation and function in the step-technique reconstruction group, a significant decrease in elasticity index and lower lip height in the vermilionectomy group, and only a significant decrease of ICD in maximal retraction in the wedge excision group.

Abstract
Twenty-seven out of eighty-five male patients who had undergone lip reconstruction using objective lip parameters, were studied to evaluate lip function after surgery. Firstly, objective lip parameters were assessed in 27 healthy volunteers; these were: intercommissural distance (ICD) at rest, in maximal lip contraction (purse), and maximal lateral retraction (wide grin), elesticity index (EI), soft-tissue gape (STG), oral access (OA), lower and upper sulcus depth (SD), lip sensitivity using two-point discrimination (2-PD). The patients were then subdivided into three groups according to the technique used: step technique, vermilionectomy wedge excision +/- 'W' plasty, Abbe flap, Bernard technique and excision. Statistical analysis was performed using two sample t-Student test. Each of the first three groups was compared to groups of normal volunteers matched for age, sex and number of individuals. The results showed a significant degree of microstomial normal lip sensation and function in the step-technique reconstruction group, a significant decrease in elasticity index and lower lip height in the vermilionectomy group, and only a significant decrease of ICD in maximal retraction in the wedge excision group.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
