Acute nasal reconstruction with forehead flap after dog bite

Delayed Reconstruction of Nasal Tip Amputation After a Dog Bite Using a Cartilage Graft and Paramedian Forehead Flap

The timing and method of reconstruction of an amputated nose due to a dog bite are still controversial. Here, we describe a delayed reconstruction using the paramedian forehead flap with a simultaneous cartilage graft to address a contracted nose from a dog bite. A healthy, 52-year-old patient was attacked by his acquaintance's dog, resulting nasal tip amputation that included cartilage. The composite graft was performed, and secondary healing resulted in a short nose deformity. Five months after the injury, a conchal cartilage graft and paramedian forehead flap were performed simultaneously to correct the shape of the deformity. At 1 year postoperatively, the flap survived without complications, and the short nose deformity was successfully corrected. In summary, immediate composite graft after a dog bite could result in a contracted nose, but the deformity can be corrected by a simultaneous paramedian forehead flap and cartilage graft.

Reconstruction of animal bite injuries to the head and neck

PURPOSE OF REVIEW

The aim if this review is to provide an update on the existing literature of animal bite treatment strategies and provide a systematic approach to animal bites from presentation to reconstruction.

RECENT FINDINGS

Dog bites cause 80-90% of animal bites with 26.8-56.5% occurring in the head and neck. Infection rates may be as low as 5.7-9.7%. Primary closure alone is sufficient in 69.8% of dog bites within the first 24 h.

SUMMARY

Animal bite injuries to the head and neck are common, especially in the younger population. Dogs cause a majority of these bite injuries. Injuries can include simple lacerations or punctures, avulsions with tissue present, or avulsions with loss of tissue. The most common locations are the cheek, nose, and lips. It is important to gather the vaccination status of the animal and patient and to administer tetanus/rabies prophylaxis if indicated. Antibiotics are typically prescribed for 3-5 and 7-14 days for uninfected and infected wounds, respectively. These wounds require evaluation, irrigation, and occasionally debridement or repair in the operating room. The type of repair is determined based on the location and extent of injury and can range from primary closure to microsurgical replantation, skin grafts, flaps, or even facial transplantation.

Nasal Reconstruction Following a Dog Bite

Bite wounds in the nose region may lead to serious esthetic problems and functional losses. The authors describe a dog bite to his nose, resulting in a defect involving the entire tip of the nose and a part of the surrounding subunits. He was repaired with forehead flap and auricular conchal cartilage acutely. To the authors' knowledge, there are very few cases of acute repair in the literature. The authors also made a literature review on this subject.

Reconstruction of a Nose Bitten and Eaten by a Dog: A Ten-Year Follow-up of a Bitten-Off Nose Replantation Performed on an Eleven-Year-Old Boy

The nose is one of the most important aesthetic units of the face. After a traumatic amputation, replantation is undoubtedly the procedure of choice, although, technically, very challenging. We report the 10-year follow-up of a partially digested nose replantation after a dog-bite in an 11-year-old boy using supermicrosurgery technique. Our report confirms that the microsurgical replantation of the nose can lead to an acceptable aesthetic result, with the sufficient growth of the replanted part in the following years. Besides the patient did not report sensibility disorders. The nose replantation in our opinion is the best reconstructive option to achieve an optimal aesthetic and functional outcome.

Management of maxillofacial injuries in bear mauling cases: a review of 20 cases

OBJECTIVES

As the craniofacial and neck regions are prime areas of injury in bear attacks, the careful management of soft and hard tissue injuries and selection of reconstructive options is of the utmost importance. This study will review the incidence and patterns of bear mauling in eastern India reported to our department and the various modalities used for their treatment over a period of 7 years. It also documents the risks of infection in bear mauling cases and the complications that have occurred.

MATERIALS AND METHODS

Twenty cases were treated over the study period. Cases were evaluated for soft and hard tissue injuries including tissue loss and corresponding management in the craniofacial region. Cases were also evaluated for other associated injuries, organ damage and related complications.

RESULTS

Various modalities of treatment were used for the management of victims, ranging from simple primary repairs to free tissue transfers. Simple primary repairs were done in 75% of cases, while the management of the injured victims required reconstruction by local, regional or distant flaps in 25%. Free tissue transfers were performed in 15% of cases, and no cases of wound infection were detected in the course of treatment.

CONCLUSION

Knowledge of various reconstructive techniques is essential for managing maxillofacial injuries in bear mauling cases. Modern reconstructive procedures like free tissue transfer are reliable options for reconstruction with minimal co-morbidity and dramatic improvement in treatment outcomes.
