Cholesterol Granuloma of the Tympanic Membrane Presenting as a Blue Eardrum

Intramembranous tympanic membrane cholesterol granuloma (CG) occurs infrequently. Here, the authors report a case of CG in the tympanic membrane presenting as a blue eardrum in the right ear. In addition, a pinhole perforation noted in the anterosuperior area revealed a brown discharge. High-resolution temporal bone CT showed a bulging mass shadow in the middle ear and a soft tissue dense lesion that filled both the epitympanum and mastoid cavity. Tympanomastoidectomy was performed under general anesthesia. New bone formation was confirmed in the mastoid antrum and epitympanum, and the epitympanum was blocked by new bone. The tympanic membrane revealed a round, brownish mass with a glistening surface and a severely thickened pars tensa. We herein report this case and review pertinent medical literature

Modified lateral rhinotomy for fronto-ethmoid schwannoma in a child: a case report

Schwannoma of frontoethmoid region is a rare presentation. We report a case of 11-year-old girl with a swelling at the root of nose and nasal dorsum. Based on clinical picture and radiological findings it was not possible to establish a definitive diagnosis. But the histopathological picture was suggestive of schwannoma. A novel surgical approach was adopted to facilitate complete removal of the tumor and provide best possible cosmetic results

Study on the Anatomical Variations of the Posterosuperior Bony Overhang of External Auditory Canal

To evaluate the extent of posterosuperior bony overhang required to be removed for proper exposure of the incudo-stapedial complex during stapes surgery. Whether an assessment can be made out about the extent of the posterosuperior bony overhang clinically or not. A prospective study. One hundred patients of Stapedial Otosclerosis were included in this study. The direction of the posterosuperior bony canal wall i.e. straight or sloping type was recorded in every patient. All the patients underwent stapedotomy operation under local anaesthesia. The amount of overhang of the posterosuperior bony canal wall required to be removed for adequate exposure of the incudo-stapedial complex during stapes surgery was recorded by using measured right-angled picks of different sizes in mm. The aim of this study is to find out the extent of posterosuperior bony overhang and to know whether the posterosuperior bony overhang is more in straight or sloping bony canal wall. Fifty-seven percent of our patients had a medially sloping posterosuperior bony canal wall and 43% had a straight canal wall, which was noted clinically before surgery. The extent of posterosuperior bony overhang was divided into 4 groups: Gr. A ≤2 mm, Gr. B 2–2.5 mm, Gr. C 2.5–3 mm, Gr. D ≥3 mm. There were 25 patients in Group A, 55 in Group B, 20 in Group C and none in Group D. So majority (i.e. 55%) patients belonged to Group B i.e. 2–2.5 mm. The posterosuperior bony overhang is more in those patients who had straight bony canal than those who had sloping bony canal. This may be clinically assessed and this observation is statistically significant (P < 0.001)
