What is the term for the insertion of tubes in the eardrum to facilitate drainage of fluid buildup?

Myringotomy is the correct term for the surgical procedure involving the insertion of tubes into the eardrum, or tympanic membrane, to allow for drainage of fluid buildup in the middle ear. This procedure is commonly performed in cases where there is recurrent middle ear infections or persistent fluid accumulation that may impair hearing and cause discomfort.

The tubes, often referred to as tympanostomy tubes, help ventilate the middle ear and prevent further build-up of fluids, allowing for equal pressure within the ear. This procedure can significantly improve the quality of life for patients, especially children, who are prone to frequent ear infections.

Other terms mentioned in the question refer to different medical concepts. Myringoplasty refers to the surgical repair of the eardrum without tube insertion, cholesteatoma describes an abnormal skin growth in the middle ear that may lead to further complications, and endolymph drainage is not related to the middle ear but refers to fluid management within the inner ear pathways associated with conditions like Meniere's disease. Understanding the specific purpose and outcomes of myringotomy clarifies its role in ear health management.
