Posterior tympanotomy is a procedure performed to access the posterior mesotympanum th-rough a mastoid exposure while preserving the posterior external auditory canal wall. It is dangereous to drill the the site of procedure, as it is surrounded by incuidal fossa superiorly, facial nerve posteriomedially, and chorda tympani nerve anterolaterally, and forms a very narrow pa-thway. There is always a risk of surgical trauma involving important surgical structures, especially facial nerve and chorda tympani nerve. The development of image-guided surgery (IGS) has significantly improved the performance of many surgical procedures by aiding the identification of surgical landmarks, improving surgical outcomes, rendering the procedure safer and more efficient, especially for beginner otologic surgery, in revision operations, in cases of massive bleeding and tumor of complex anatomy. To see how IGS could help otologic surgeons to identify fine, important structures during posterior tympanotomy, we report a case of posterior tympanotomy in chronic otitis media, which was done using the image-guided surgical technique.

Nasopharyngeal stenosis (NPS) is a rare condition and classified as primary NPS (due to a disease process as syphilis) or secondary NPS (due to a surgery or radiotherapy) according to the etiology. Patients with NPS suffer significant morbidities, including nasal obstruction, phonatory changes, sleep disordered breathing, dysphagia, and otologic disturbances. Treatment modalities include wide range of strategies, such as local rotation flaps, free flaps, Z-plasty, prolonged stenting, insertion of obturators, and laser excision. However, treatment is difficult, often resulting in only short-term symptom relief and restenosis. The authors experienced a case of NPS following revisional palatopharyngoplasty in a 50-year-old man, which was treated successfully with balloon dilatation and topical mitomycin-C application. We present the etiology, symptoms, and treatment of this rare disease entity with a review of the literature.

Congenital aural atresia (CAA) is usually accompanied by an anomalous course of facialnerves, which may run over the round window niche toward the promontory in some cases ofCAA. Very rarely, cochlear malformation might coexist at the same ear which has CAA, inwhich case cochlear implantation can be difficult due to anomalous facial nerve. Herein wepresent a case of cochlear implantation performed in a child who had CAA along with cochlearhypoplasia and cochlear nerve aplasia. The mastoid segment of facial nerve was displacedanteriorly, running over the round window niche. The surgery was done successfully usingthe round window approach without facial nerve injury.

The term concha bullosa describes aerated turbinate and it is most common on middle turbinate. Symptoms of concha bullosa depends on the amount of pneumatization and location. Concha bullosa without symptoms does not need surgical treatment, however, surgical treatment is indicated when it causes nasal obstruction. There are many reports of concha bullosa because it is a common anatomic variation. Despite many reports of concha bullosa, there is no definite statistics on the size of concha bullosa, and there has been no reports on what its largest size is. This report deals with a giant concha bullosa of middle trubinate of 4.5 cm in length, 2.2 cm in width size causing complete nasal obstruction.
