Final answer:
The most common surgery for tubotympanic type of CSOM is myringoplasty, which repairs the eardrum. If ossicles are also damaged, ossiculoplasty may be performed. For severe cases, tympanoplasty or mastoidectomy could be necessary.
Step-by-step explanation:
Common Surgery for Tubotympanic Type of CSOM
The most common type of surgery performed for the tubotympanic type of Chronic Suppurative Otitis Media (CSOM) is called myringoplasty. This surgical procedure aims to repair the perforation in the tympanic membrane (eardrum) to restore its integrity and improve hearing while preventing recurrent infections. In some cases, if there is also damage to the ossicles (the small bones within the ear responsible for sound conduction), an operation called a ossiculoplasty may also be performed to reconstruct these bones.
In cases where there is significant chronic infection or cholesteatoma (an abnormal skin growth in the middle ear behind the eardrum), a more extensive procedure known as a tympanoplasty or mastoidectomy may be required. These surgeries are more complex and involve not only the repair of the eardrum but also the removal of infection from the mastoid bone and reconstruction of the middle ear structures as needed.
