  1. Potential Uses of Oasis® Wound Matrix MOHS (Micrographic Surgery)

The MOHS surgical technique was first described by Dr. Mohs in the 1930's. This surgical approach  is the most precise method of treating skin cancer that results in the highest cure rate with the maximal tissue conservation. 

The hallmarks of the MOHS approach is a tangential (rather than perpendicular) excision of the tumor that allows for 100% of the tumor margin to be examined such as the margins of the remaining wound are free of cancer.

The MOHS surgeon has a dual role as surgeon and pathologist. The tumor borders are marked out on the skin and then the tumor is removed in thin slices which are then examined under the microscope until the slices around the entire border are free of the tumor.

The tumors removed are:
  • Basal cell carcinomas most commonly present on the ear, nose, eyelid or lip as these sites have the highest recurrence rates when more traditional surgical removal is performed.

  • Squamous cell cancers of the face (in the same shaded area) in addition to tumors of the penis, digits and lesions greater than 2 cm. in diameter are approached using the MOHS method in order to provide the highest cure rate.

  • Melanoma is not commonly removed using MOHS.

The procedure is usually performed in an ambulatory setting which contains the necessary surgical and pathology equipment.

  • The full thickness wound that is produced is closed by the use of a local flap, skin grafts or allowed the wound to close by contraction.

Tissue Engineered Wound Matrix would be ideal for filling in the defect left - after removing the full thickness lesion and allowing the surface to re-epithelialize without leaving a defect or a scar.
