Comparison of wound closure by means of dog ear repair and elliptical excision

Round Excisions Lead to Shorter Scars and Better Scar Positioning than Traditional Elliptical Excisions

“…Interestingly, our results do not correspond particularly well with a previous report mentioning the benefits of excision with dog ear repair [11], in which the number of dog ears was found to be in proportion to the final length of the wound. The reason for this is that some defects after tumor marginal excisions are not circular, but have an irregular shape according to the tumor margin.…”

Scar Area and Cosmetic Outcome After Circular and Elliptical Excision of Small Skin Lesions

“…Only a few studies have evaluated the results of routine elliptic excisions. 6,7 Circular excision has been shown to result in significantly shorter wound length than elliptical excision. 6,7 Also, one study of the optimal direction of wound closure in circular excision found this direction to be different from what was initially estimated in half the cases, thus enabling a better oriented wound closure line during the procedure.…”

The Influence of Rotator Cuff Tear Size and Repair Technique on Creation and Management of Dog Ear Deformities in a Transosseous Equivalent Rotator Cuff Repair Model

“…Wounds on convex surfaces, similar to the rotator cuff footprint at the greater tuberosity, are more susceptible to this deformity. 21 Techniques used in plastic and dermatologic surgery to manage dog ear deformities, including fusiform excision, S-plasty, M-plasty, and V-excision, 2,[6][7][8]19,21,22 are not applicable to dog ear deformities in rotator cuff repairs.…”

“…Commonly encountered in other surgical wounds as well, dog ear deformities are the result of an asymmetric puckering or accumulation of tissue, typically in the center or at the apices of an incision. The etiology and management of these deformities are well described in the plastic and dermatologic surgery literature 2,6,7,19,21,22 ; however, there is a relative paucity of literature regarding the causes and implications of dog ear deformities in rotator cuff repairs. This study was performed to quantify the effects of dog ear formation on rotator cuff footprint restoration after repair as well as to assess the association between rotator cuff repair method and the formation and management of dog ear deformities in a human cadaveric model.…”
