The nose and sinus manometry: a bio-physical model applied to functional endoscopic sinus surgery

Area of Science:

• Otolaryngology
• Rhinology
• Surgical Innovation

Background:

• Effective sinus ventilation relies on the regular anatomy of internal nasal structures, particularly the maxillary sinus ostium.
• Nose and sinus manometric measurements can demonstrate superior functional outcomes with conservative surgical techniques.

Purpose of the Study:

• To compare the functional efficacy of conservative versus non-conservative endoscopic sinus surgery on maxillary sinus ventilation.

Main Methods:

• Thirty patients were divided into two groups: Group A (conservative endoscopic sinus surgery) and Group B (non-conservative endoscopic sinus surgery).
• Maxillary sinus ostium manometry was performed 30 days post-surgery using a digital manometry system.
• Functional efficacy was calculated as a percentage index by comparing patient pressure values to a standard group without sinonasal pathologies.

Main Results:

• The average maxillary sinus functional efficacy was 98.35% for Group A and 49.73% for Group B.
• Statistical analysis (Student t test) showed a significant difference between Group B and the standard group (p < 0.4).
• Patients undergoing more aggressive endoscopic surgery exhibited inadequate sinus ventilation compared to the standard group.

Conclusions:

• Conservative endoscopic sinus surgery preserves and enhances maxillary sinus ventilation.
• Non-conservative, aggressive endoscopic approaches lead to significantly impaired sinus ventilation.
• Preserving nasal anatomy through conservative surgery is crucial for optimal sinonasal function.
