in perforated tympanic membrane and William's test is an essential tool to assess the ETF in intact tympanic membrane. Our present study is undertaken to assess the ETF in patient with CSOM with reference to its treatment outcome. Based on impedance audiometry fi ndings, patients of tubotympanic disease are categorized as totally impaired, partially impaired, and normal ETF. Patients with normal ETF were taken up for myringoplasty. Patients with totally impaired ETF irrespective of middle ear mucosal status (dry or wet) were taken up for cortical mastoidectomy with tympanoplasty. Patients with partially impaired ETF, with dry middle ear mucosa were taken up for myringoplasty and those with wet middle ear were taken up for cortical mastoidectomy with tympanoplasty. ABSTRACT Aims and Objectives:To assess the eustachian tube function (ETF) and to evaluate the treatment outcome of chronic suppurative otitis media (CSOMtubotympanic type) in relation to eustachian tube dysfunction. Materials and Methods: Prospective study for a period of 2 years; the study comprises of 100 patients diagnosed to have CSOM (tubotympanic type). ETF was assessed by Toynbee's test. Patients with normal ETF were taken up for myringoplasty. Patients with totally impaired ETF irrespective of middle ear mucosal status (dry or wet) were taken up for cortical mastoidectomy with tympanoplasty. Patients with partially impaired ETF, with dry middle ear mucosa were taken up for myringoplasty and those with wet middle ear were taken up for cortical mastoidectomy with tympanoplasty. Results and Analysis: The ETF in these patients was analyzed and graft uptake was assessed clinically in reference to ETF status. The results are tabulated and analyzed using Chi-square test using number cruncher statistical system (NCSS) software. In our study, preoperative ETF had a highly signifi cant P value0.0005. Conclusion: Methodology of treatment adapted for CSOM patients based on ETF proves that the eustachian tube plays a major role in the uptake of graft.

During the time period of August 2009 to August 2010, five cases of odontogenic keratocyst were admitted and treated under the care of Department of Otorhinolaryngology, MGMC and RI, Puducherry. Patients came to the ENT OPD with history of swelling in the cheek region, nasal obstruction, numbness in the upper alveolar region. On examination diffuse swelling of size 7 × 3 cm in one patient and size of 5 × 3 cm in two patients, and other two patients size of 6 × 3 cm present in the maxillary region with ill defined borders, the swelling was firm in consistency, no warmth, non tender. Anterior rhinoscopy reveals mass pushing the lateral wall medially, septum pushed to opposite side, mucopus present in nasal cavity, airway reduced on the side of swelling. On examination of oral cavity, a small granulation of size 1.0 × 0.5 cm present in two patient and swelling of size 1.5 × 1.0 cm seen in two patients in vestibule, no swelling in one patient and swelling of size 3 × 2 cm seen in hard palate of two patients and no swelling in three patients, no loosening of tooth seen in all patients. X-ray PNS reveals maxillary hazziness, diagnostic nasal endoscopy reveals lateral wall of nose pushed medially and septum pushed to opposite side. FNAC reveals resolving inflammatory aspirate in one patient, few macrophages seen in two of patients, few keratinocytes seen in two of the patients. CT nose and PNS revealed a large cystic lesion with erosion of anterior and medial wall and floor of maxilla in relation to the root of the last molar tooth in two patients and there is erosion of anterior and medial wall in other three patients. A combined endonasal and external sublabial (Caldwell-luc) approach was performed in four patients and the cystic lesion was removed and in other one patient only endonasal approach was done and cystic lesion was removed and sent for biopsy. Biopsy sent for HPE revealed odontogenic keratocyst.

Petrified ear is an uncommon condition, usually asymptomatic, whether by calcification or ossification, results in a rigid and immalleable ear. In cases of extreme discomfort, surgical intervention like conchal reduction through a posterior incision has been employed.

AIMS AND OBJECTIVES:To study the various sites of perforation in patients with chronic suppurative otitis media (CSOM)-Safe type and to study the relationship of the perforator quadrant with the degree of hearing loss. MATERIALS AND METHODS: Cross sectional prospective study conducted between June 2014 -June 2015 in the department of ENT; 103 ears of 88 patients with tympanic membrane perforation-chronic suppurative otitis media (Safe type) at Chettinad hospital and research institute; Chennai. RESULTS: The sites/locations of perforations on the tympanic membrane were correlated with their meanhearing levels (dB) using chi-square test. Out of 103 perforated tympanic membranes, 29 had all four quadrant perforation (28.16%). Out of these 29 patients 7 had severe conductive hearing loss (24%) and 16 had moderate conductive hearing loss (55%). CONCLUSION: The location of perforation on the tympanic membrane has effect on the magnitude of hearing loss. It has a significant impact in chronic suppurative otitis media.
