A 'residual cholesteatoma' may develop if the initial surgery failed to completely remove the original; residual cholesteatomas typically become evident within the first few years after the initial surgery. A 'recurrent cholesteatoma' is a new cholesteatoma that develops when the underlying causes of the initial cholesteatoma are still present.
Over time, these became formalized as mastoidectomies. Mastoidectomies were used to treat infections such as otitis media, or abnormal skin cell growth near the middle ear. [2] Over time, they were adapted to help treat hearing issues such as tinnitus. [5] Mastoidectomies have also been used in the modern practice of placing cochlear implants. [6]
Surgery for cholesteatoma offers the most advantages for using the endoscope instead of the microscope. Failures in cholesteatoma surgery are most common in certain areas of the anatomy of the tympanic cavity, such as the facial recess, sinus tympani, anterior attic, and the protympanum which are poorly accessed with the microscope.

Facial palsy is considered severe if the person is unable to close the affected eye completely or the face is asymmetric even at rest. Corticosteroids initiated within three days of Bell's palsy onset have been found to increase chances of recovery, reduce time to recovery, and reduce residual symptoms in case of incomplete recovery.

A seroma is usually caused by surgery. Seromas are particularly common after breast surgery [3] (e.g., mastectomy), [4] abdominal surgery, and reconstructive surgery. It can also be seen after neck surgery, [1] thyroid and parathyroid surgery, [5] and hernia repair. [2] The larger the surgical intervention, the more likely that seromas form.

It is thought that it may be caused by the body's inflammatory response to surgery, stress hormone release during surgery, ischemia, or hypoxaemia. [5] [6] Post-operative cognitive dysfunction can complicate a person's recovery from surgery, delay discharge from hospital, delay returning to work following surgery, and reduce a person's quality ...
Although laparoscopy in adults is widely accepted, its advantages in children are questioned. [19] [20] Benefits of laparoscopy appear to recede with younger age. Efficacy of laparoscopy is inferior to open surgery in certain conditions such as pyloromyotomy for infantile hypertrophic pyloric stenosis.
