Abstract

Carcinoma of Hypopharynx is challenging to manage because of the delayed presentation resulting in advanced nature of the disease at the time of diagnosis . In advanced cases with T3 and T4 tumors usually require total laryngectomy and total pharyngectomy and this results a reconstruction challenge because of the circumferential nature of the defect. Traditional reconstruction has been through gastric pull but recently tubed radial forearm free flap is increasing being employed in such reconstructions. Gastric pull has significant disadvantages because of the increased morbidity, need of second surgeon and prolonged hospital stay. Free Flap need micro vascular expertise not widely available and some postradiated patients are extremely challenging because of the recipient vessel status. Hence, we started using tubed supraclavicular flap in the reconstruction of total pharyngectomy defects and here we present our experience including the challenges encountered in 7 patients so far. 4/7 patients had post cricoid carcinoma and 3/7 had pyriform sinus carcinoma with extension to postcricoid region. 5/7 had salvage surgery following recurrence with Chemo-radiation. The indications for this type of reconstruction in our study included only circumferential defects with lower of the defect being above the thoracic inlet. Average length of defect was around 7 cms with range being 5.5 to 9 cm. Wide supraclavicular flap was harvested over the deltoid area usually from the side of the defect and tubed over a Montgomery salivary bypass tube before suturing over the defect.
Complications included Pharyngo cutaneous fistula in 4 patients out of which 3 resolved with conservative treatment. We conclude that tubed supraclavicular flap is an easy less morbid alterative that should receive more attention in the reconstruction of circumferential defects which lie above the thoracic inlet.
