BACKGROUND: Atelectasis can be defined as the state in which parts or all of the tympanic membrane are found to retract medially. When only a part of the tympanic membrane is involved, it is most commonly the pars flaccid or the posterior quadrant of the pars tensa. Aclectasis of the middle ear cavity occurs in advanced chronic otitis media with effusion. Atelectasis with effusion, and further possible complications include adhesive otitis media, ossicular disruption, cholesteatoma, and sensotineural hearing loss.

CASE REPORT: A case came to the clinic having discomfort and earache in right ear and having hearing loss in right ear since last 2 years. The patient also has hypothyroidism. No history of abnormal sound perception and Dizziness. History of Slight Ear discharge and Otalgia had been in Right ear since few years. And also earache is occasionally in Right Ear. Objective tests were done like videootoscopic view, Pure tone Audiometry, Tympanometry and also surgical management and medication.

MAIN OUTCOME MEASURES THROUGH AUDIOMETRY TESTING: Postoperative pure tone average air-bone gap for four frequencies (500, 1000, 2000, 4000 Hz) compared with preoperative levels.

CONCLUSION:

This staging system offers an effective treatment algorithm for pars tensa retractions and management of type III and IV retractions via cartilage tympanoplasty with or without ossicular reconstruction and is a proven treatment modality.
