[Perfusion manometry in the evaluation of postoperative swallowing function following various reconstructive
1Klinik für Hals-, Nasen- und Ohrenheilkunde, Medizinischen Universität zu Lübeck.
Background:
The swallowing function can be restored after large oncologic resections in the upper aerodigestive tract with microvascular anastomosed transplants.
Patients And Methods:
With the help of the perfusion manometry we would like to demonstrate the functional advantages of this reconstruction method. We examined three reconstructed regions: tongue with 15 patients, soft palate with 11 patients, and the laryngeal and pharyngeal complex after total laryngopharyngectomy with 17 patients.
Results:
Patients with reconstructed tongue or soft palate reached 69% or 74% of their pressure compared to normal values.
Conclusions:
We demonstrated that although normal pressure values were not reached after reconstruction of large defects with microvascular anastomosed transplants; these reconstruction methods restored the pressure gradient essential for swallowing, with a higher pressure of the soft palate and a lower pressure of the base of tongue.
