Abstract:
The history of the Eustachian tube spans ancient Egyptian and Greek texts, Islamic medicine, and Renaissance anatomy. From early misconceptions to Bartolomeo Eustachi's anatomical insights and Valsalva's functional discoveries, understanding evolved. Modern otology owes much to pioneers like Toynbee and Politzer, whose innovations shaped the diagnosis and treatment of Eustachian Tube Dysfunction. Surgical management evolved from risky catheterization procedures to refined surgical techniques. Myringotomy and tympanostomy tubes marked key milestones. Recently, endoscopic advances and balloon dilation have revolutionized treatment. Modern understanding of the spectrum of Eustachian Tube Dysfunction-from obstructive to patulous-continues to shape otologic practice.

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
