Necrotizing fasciitis of the face: current concepts in cause, diagnosis and management.

PURPOSE OF REVIEW

Necrotizing fasciitis of the face is uncommon but potentially life threatening. With adequate multidisciplinary treatment, mortality and has significantly improved. This article highlights current concepts and supporting literature in the management of facial necrotizing fasciitis.

RECENT FINDINGS

Management of necrotizing fasciitis involving the face requires a multisciplinary team approach, including early medical and surgical intervention. With early haemodynamic support, broad spectrum antibiotics and aggressive surgical debridement, mortality has reduced significantly. Soft-tissue reconstruction can be effectively utilized once the infection has been adequately treated. Although some adjunctive treatment such as vacuum assisted closure dressing has shown to be of benefit, other treatments such as hyperbaric oxygen remains controversial.

SUMMARY

Necrotizing fasciitis is an aggressive soft tissue involving that rapidly spreads along fascial planes. Necrotizing fasciitis involving the face is rare owing to its rich blood supply but is also difficult to manage due to the complex regional anatomy. Common sources are odontogenic, sinugenic, peritonsillar or salivary gland infections and often polymicrobial. The principles of treatment include early and aggressive haemodynamic support, broad spectrum antibiotics and aggressive surgical debridement. Often times repeat debridements following close monitoring is required. Reconstructive options are viable only after the infection has been adequately treated. Although mortality has significantly improved, mediastinal involvement, multiple comorbidities and delayed treatment confers a worse prognosis.
