Dog bite injury — alar repair with composite graft

Abstract

Dog bite injuries are an important emergency. Facial dog bites can lead to disfigurement and stigmatization. Dog owners themselves are the usual victims of facial dog bites. Early surgery provides best results. A 28-year-old male patient presented 1 year after he had been bitten on his nose by his own dog. The pronounced nasal disfigurement with nostril stenosis was treated by reconstruction using a free composite graft from the crus of the ipsilateral ear with good results. Delayed reconstruction can provide satisfying results.

Surgical Management of Animal and Human Maxillofacial Bites: A Comprehensive Review

“…7,15,23,64,66,70,74 Not only aesthetic complaints but also functional problems are very often encountered. 73 When cartilages such as nose and ear are affected, another cartilage can serve to allow further reconstruction. 43,61,69 Free grafts must not exceed 1cm to avoid compromising vascularization.…”

“…43,61,69 Free grafts must not exceed 1cm to avoid compromising vascularization. 73 Immediate flaps and microvascular anastomosis are successful methods to prevent further necrosis. 64,70,73 More successful outcomes are associated with arterial and venous anastomosis.…”

“…73 Immediate flaps and microvascular anastomosis are successful methods to prevent further necrosis. 64,70,73 More successful outcomes are associated with arterial and venous anastomosis. 7,43,64,66 Reconstructive flaps, scar revision and grafts may be required in a significant number of cases.…”

“…7,43,64,66 Reconstructive flaps, scar revision and grafts may be required in a significant number of cases. 6,7,9,12,14,18,23,[36][37][38]43,47,54,63,73,75 Depending on the extent of the wound, a tissue expander might be a suitable alternative. 43 Hyperbaric oxygen therapy is considered a safe and effective protocol to prevent tissue necrosis.…”

Reconstruction of Distal Nasal Defects With a Large Postauricular Skin-Fat-Fascia Composite Graft

“…The use of a skin graft and composite graft in nasal reconstruction may provide a desirable alternative to skin flaps, with satisfactory results previously demonstrated 12–14 . However, composite grafts reportedly have an increased risk of central necrosis once the diameter exceeds 1.0 cm 15 .…”
