If a parotid duct injury is diagnosed at the time of tumor extirpation, then surgical repair of the duct should be attempted, but if surgical repair is not possible or if an injury remains unrecognized until well after tumor extirpation, then surgery is not necessary. In such cases, conservative, nonsurgical measures, such as treatment with botulinum toxin, will provide excellent results.

We investigated the change in optical properties and vascular parameters to characterize skin tissue from mild photodamage to actinic keratosis (AK) with comparison to a published photodamage scale. Multi-wavelength spatial frequency domain imaging (SFDI) measurements were performed on the dorsal forearms of 55 adult subjects with various amounts of photodamage. Dermatologists rated the levels of photodamage based upon the photographs in blinded fashion to allow comparison with SFDI data. For characterization of statistical data, we used artificial neural networks. Our results indicate that optical and vascular parameters can be used to quantify photodamage and can discriminate between the stages as low, medium, and high grades, with the best performance of ∼70%, ∼76% and 80% for characterization of low-medium-and high-grade lesions, respectively. Ultimately, clinicians can use this noninvasive approach for risk assessment and frequent monitoring of high-risk populations.

The 3-point stitch and the modified suspension suture techniques are easy and simple methods that can be incorporated into reconstruction after MMS for defects of variable depth covering any multisubunit perialar region to prevent or correct INV collapse.
