The usefulness of the IMAP propeller flap for trachea and tracheostome reconstruction after resection of parastomal recurrence of squamous cell carcinoma following salvage total laryngectomy.

PURPOSE: Parastomal recurrence of squamous cell carcinoma (SCC) with tracheal involvement following salvage total laryngectomy after prior concurrent chemoradiotherapy is one of the most insidious challenges in head and neck surgery because a complex reconstruction is often required for covering a large area of skin loss, filling the dead space beneath, tracheal reconstruction and suspension, and tracheostome resurfacing. The aim is to describe our experience with the internal mammary artery perforator (IMAP) propeller flap for tracheal and tracheostome reconstruction and neck resurfacing after parastomal and cervical trachea resection, especially for suspension and anchoring the stump of the residual distal trachea to the island flap itself.

METHODS

We describe IMAP flap reconstruction after resection of parastomal recurrence of SCC requiring cervical trachea resection in five patients between January 1, 2005 and August 30, 2019.

RESULTS

IMAP propeller flap was successfully used for reconstruction after complex resection of parastomal recurrence of SCC with cervical trachea involvement in all cases. The mean length and width were, respectively, 16.8 cm (range 13-23) and 6.9 cm (range 5.5-8). We did not report complications of both the donor and the recipient site. Pharyngo-cutaneous or tracheoesophageal fistulas and wound dehiscence were not observed.

CONCLUSIONS

to the best of our knowledge, this is the first report about the use of the IMAP propeller flap in this more complex clinical setting and we provide the message that this surgical procedure is worthy of consideration.
