Background:
To compare clinical and functional outcomes of different reconstructive options for a hypopharyngeal defect after head and neck cancer surgery.
Methods:
We retrospectively analyzed 127 cases who had undergone hypopharyngeal reconstruction, as either pedicled (25 cases), fasciocutaneous free flap (FCFF) (41 cases) or visceral flap (61 cases).
Results:
Overall incidence of flap compromise was 10.2% (13 cases), and there were no statistically significant factors associated with flap compromise. Fistula or stenosis occurred in 36.2% (46 patients) and 23.6% (30 patients), respectively. Salvage surgery increased the risk of fistula formation (OR 2.93, 95% CI 1.32-6.52, p < 0.01), whereas FCFF showed a protective effect for stenosis, compared to pedicled flap (OR 0.09, 95% CI 0.01-0.47, p < 0.01).
Conclusion:
Outcomes of hypopharynx reconstruction can be successful if different flap options are used appropriately according to the type of defect and previous treatment history of the patient.

Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...
