Abstract
Objectives
This study aimed to describe the technique and clinical outcomes of using a palatal
mucoperiosteal flap for oro-nasal fistula closure following resection of maxillary
sinus cancer.
Methods
The study was conducted with the permission of the internal review board of the Japanese
Red Cross Wakayama Medical Center. Five consecutive cases from 2016 to 2020 of surgically
treated maxillary sinus cancer in which the oro-nasal fistulas were closed using a
palatal mucoperiosteal flap were retrospectively reviewed.
Results
Following tumor resection, the oro-nasal fistula was closed using a palatal mucoperiosteal
flap. Complete separation of the oral and nasal cavities was achieved in four patients.
Oral intake was resumed within two weeks in four patients. All the patients were able
to eat foods similar to those in the preoperative period. Their postoperative speech
function was excellent, with no difficulty in communicating with others.
Conclusion
In the selected cases of maxillary sinus cancer, preservation of the palatal mucosa
and closure of an oro-nasal fistula using a palatal mucoperiosteal flap was possible
with reasonable outcomes for swallowing and speech functions. The use of this local
flap is recommended as a minimally invasive procedure that can be performed especially
in patients with limited physiological reserves which preclude free flap reconstruction.
