Aspiration Prevention Surgery: Clinical Factors Associated With Improvements in Oral Status Intake and Suction...

Area of Science:

• Otolaryngology
• Neurology
• Gastroenterology

Background:

• Severe dysphagia often necessitates aspiration prevention surgery (APS).
• Limited data exists on APS outcomes, complications, and risk factors.
• Understanding APS efficacy is crucial for managing swallowing disorders.

Purpose of the Study:

• To investigate clinical features of patients undergoing APS.
• To evaluate the impact of APS on oral intake status and suction frequency.
• To identify risk factors for postoperative complications and predictors of improved oral intake.

Main Methods:

• Retrospective analysis of 100 patients undergoing APS from 2010-2021.
• Assessment of Functional Oral Intake Scale (FOIS) and suction frequency pre- and post-surgery.
• Analysis of risk factors for complications and factors influencing oral intake improvement.

Main Results:

• 78% of patients showed improved FOIS scores post-APS.
• Suction frequency decreased in 85% of cases.
• 10% experienced complications (wound infection, bleeding), all resolved. Higher preoperative FOIS scores correlated with increased complication risk (p=0.02).

Conclusions:

• APS effectively improves oral intake and reduces suction requirements.
• The procedure is safe with appropriate perioperative care, applicable even to medically fragile patients.
• Further research into optimizing APS and managing complications is warranted.
