Advanced-stage lesions of the hypopharynx or tongue base often involve
the larynx. The difficulty of reconstructing large partial laryngopha
ryngeal defects can result in total laryngectomy being performed to av
oid the assumed problems with aspiration. This article describes the f
irst reported experience using the pectoralis musculocutaneous flap fo
r primary one-stage reconstruction of laryngopharyngeal defects follow
ing resection of advanced-stage lesions, to reconstruct both the laryn
geal and the pharyngeal components of the defect. In this group of 21
patients, there were 16 with hypopharyngeal and 5 with tongue base can
cers. Two had received prior treatment, and all received some form of
postoperative radiotherapy and/or chemotherapy. Six patients experienc
ed complications, including two fistulae, three wound infections, two
myocardial infarctions, and one colon perforation. There were no insta
nces of stenosis of the reconstructed segment. The length of hospitali
zation ranged from 9 to 60 days, the average being 17 days. Forty-seve
n percent (21) of the patients were not tolerating an oral diet at the
time of discharge. However, 15 patients (71%) ultimately were eating
by mouth, with 13 (62%) achieving an oral intake of liquids and solids
. This analysis supports the hypothesis that the pectoralis major musc
ulocutaneous flap is an effective one-stage primary reconstruction tec
hnique for laryngopharyngeal defects in patients either who have recei
ved prior therapy or who will receive postoperative therapy.
