Abstract

Objective:

To determine whether bivalve inlay cartilage-perichondrium myringoplasty (BCM) is successful in closing tympanic membrane perforations in an office setting.

Study Design:

Retrospective case review.

Subjects And Methods:

Adult patients with chronic perforations underwent BCM under local and topical anesthesia. Success was defined as complete closure of perforation at follow-up of at least 1 month. Predictors of success were identified by comparing the success and failure groups on pre- and postoperative pure tone average (PTA), patient demographics (age, gender), and characteristics of the perforations (size, location, duration, etiology).

Results:

A total of 145 procedures were performed and the patients were followed for 1 to 78 months. The success rate for perforations smaller than 4 mm was 75 percent. Size of the perforation, and pre- and postoperative PTAs were significantly different between the two groups. The only significant predictors of success were preoperative PTA and size of perforation.

Conclusions:

BCM is a viable option for closure of small and medium-sized perforations in an office setting.

Mitral Stenosis III: Medical Management

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

Anatomy of the Ear

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

The Auditory Ossicles

The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
