Which portion of the tympanic membrane is known as the pars flaccida?

The pars flaccida is indeed identified as a small triangular-shaped area located at the top edge of the tympanic membrane. This segment is considered less tense compared to the rest of the tympanic membrane, which is primarily known as the pars tensa. The pars flaccida has a unique anatomical position, being situated above the malleus and forming part of the upper quadrant of the tympanic membrane.

This area plays a role in the middle ear's function and is significant for certain conditions such as cholesteatomas, which are growths that can develop in that region due to retraction of the membrane. Understanding the features and location of the pars flaccida is crucial in the identification and management of related ear disorders.
