[Application of vacuum wound therapy with split thickness skin grafts in the head and neck area].

OBJECTIVE: In vacuum wound therapy (VAC) a negative pressure can continuously clean effusions and enhance the formation of granulation tissue significantly. In visceral, trauma and burns surgery this technique is used frequently in critical wounds. In the head and neck area there is limited experience and publications. Especially in the combined use of split-thickness-skin grafts (STSG) and VAC there is no published evidence.

MATERIAL AND METHODS: A retrospective database analysis was done and resulted in 36 single VAC therapies in 13 patients. They were treated between 2012 and 2017 in the Department of Otorhinolaryngology of the University Medical Center Ulm, Germany. A data analysis was performed relating to indications, diagnoses, comorbidities as well as the clinical course and outcome with special focus on STSG.

RESULTS: Besides classical indications as pharyngo-cutaneous fistulas and troublesome would healing after flap surgery, 7 cases of VAC use with split-thickness skin grafts were identified. The median treatment duration was 11 days, the VAC dressing was changed twice in average, the median negative pressure was 70 mmHg. Wound closure was successful in 13/13 cases, in 7/13 cases wound closure was achieved by split-thickness skin graft with synchronous VAC therapy, 4/13 cases showed healing by secondary intention, in 2/13 cases a local or distant flap was used.

CONCLUSIONS: We first describe the successful use of VAC therapy in combination with STSG in the head and neck area. This was effective in radiated patients and in critically ill patients with sepsis and necrotizing fasciitis.
