A new technique to expose the hypopharyngeal space: The modified Killian's method

Area of Science:

• Medical Endoscopy
• Otolaryngology
• Gastroenterology

Background:

• Advanced endoscopic technology allows for early detection of superficial cancers.
• Effective visualization of the hypopharyngeal space is crucial for detecting early-stage lesions.
• Conventional head positions limit the exposure of the hypopharynx during endoscopic examination.

Purpose of the Study:

• To introduce a novel head positioning technique, the Modified Killian's method, for enhanced hypopharyngeal visualization.
• To demonstrate the effectiveness of the Modified Killian's method in widening the hypopharyngeal space.

Main Methods:

• The Modified Killian's method involves modifying the traditional Killian position by further forward bending.
• Additional maneuvers include head turning and the Valsalva maneuver while in the modified position.
• These combined actions aim to maximally expand the hypopharyngeal space for endoscopic observation.

Main Results:

• The Modified Killian's method provides significantly wider exposure of the hypopharyngeal space compared to conventional head positions.
• Conventional methods offer insufficient opening of the hypopharyngeal area.

Conclusions:

• The Modified Killian's method facilitates complete observation of the hypopharyngeal circumference and cervical esophageal entrance.
• This technique is potentially indispensable for hypopharyngeal examination and the detection of hypopharyngeal cancers.
