Chondrosarcoma is a rare non-epithelial tumor comprising of 10-20% of primary bone tumor. The nasal septum is a rare site for its occurrence. We present one such case of chondrosarcoma of the nasal septum who was treated with endoscopic removal followed by post operative radiotherapy and discuss the relevant clinical presentation, diagnosis and treatment and review the literature also.

<p class="abstract"><strong>Background:</strong> Chronic otitis media (COM) with or without cholesteatoma causes ossicular erosion/ destruction which leads to conductive hearing loss. Ossiculoplasty is to reconstruct the hearing mechanism in ear after eliminating the disease from the middle ear. In our study we used ventilation tubes or grommet as partial ossicular replacement prosthesis (PORP) for the reconstruction of the ossicular chain especially when the stapes is mobile. The objective of the study is to assess the degree of hearing improvement by using grommet as PORP in type III tympanoplasty.</p><p class="abstract"><strong>Methods:</strong> It was an observational study from July 2018 to July 2019. 20 patients with COM undergoing canal wall up or canal wall down mastoidectomy with intraoperative ossicular chain erosion with intact stapes suprastructure were included in this study. Post-operative hearing gain and graft uptake was assessed at 3^rd month.  </p><p class="abstract"><strong>Results:</strong> Among these 20 patients 15 underwent canal wall up mastoidectomy with type III tympanoplasty and 5 underwent canal wall down procedure with type III tympanoplasty. Incus was eroded in 17 cases, malleus in 2 cases and malleus with incus eroded in 1 case. The pre op average airborne gap was 38 dB and mean improvement of 12 dB was observed at third month.</p><p class="abstract"><strong>Conclusions:</strong> Grommet tube used as PORP is an effective alternative in the reconstruction of ossicular chain with good hearing improvement.</p>

<p class="abstract"><strong>Background:</strong> Chronic rhinosinusitis (CRS) is a common and persistent illness that otorhinolaryngologists encounter commonly. It is an important cause of morbidity and accounts for major loss of income. Anatomical variations of the lateral wall of the nose have been reported which can predispose to CRS. The aim of the present study was to determine the percentage of concha bullosa in patients with CRS and to ascertain its relationship with chronic rhinosinusitis.</p><p class="abstract"><strong>Methods:</strong> 100 patients attending the ENT outpatient department, Bangalore Medical College and Research Institute between December 2018 and 2019 were included in the study. Patients clinically diagnosed as CRS underwent diagnostic nasal endoscopy (DNE) and computed tomography (CT) scan of nose and paranasal sinuses, following which the relationship between concha bullosa and CRS was determined. The results were tabulated in excel sheet. Chi square test was applied for qualitative data.  </p><p class="abstract"><strong>Results:</strong> Of the 100 patients of CRS, 40 were males and 60 females. Of the 40 male patients, 16 showed presence of concha bullosa and of the 60 female patients, 28 showed concha bullosa. Headache (92%) was the most common presenting symptom in our study. A statistically significant correlation was noted between the presence of concha bullosa and chronic maxillary sinusitis (p value &lt;0.05).</p><p class="abstract"><strong>Conclusions:</strong> Concha bullosa is one of the most common anatomical variations of the lateral wall of the nose. The presence of concha bullosa plays a significant role in the development of chronic rhinosinusitis particularly in chronic maxillary sinusitis.</p>

To evaluate the efficacy of endoscopic myringoplasty and comparison with conventional myringoplasty. Materials and Methods: Sixty cases of clinically diagnosed chronic supportive otitis media with dry central perforation were taken into account of which 30 cases were undergone endoscopic myringoplasty and 30 cases undergone conventional myringoplasty. All patients were followed up on 3rd, 7th, 15th day, 6th weeks, 3rd and 6th months after surgery. Results:The tympanic membrane's perforation healing rate was 86% (26/30), in conventional group of myringoplasty and 83% (25/30) in endoscopic group of myringoplasty and average hearing gain in conventional group was 13.96 dB and in endoscopic group was 15.03 dB. Conclusion:The surgical outcome of endoscope assisted myringoplasty in terms of graft uptake and hearing improvement was comparable to the conventional microscope assisted myringoplasty, but in terms of cosmesis and postoperative recovery patients in the endoscope group had better results.

In patients with diabetes mellitus, by the time hearing loss is detected using conventional tuning for ktests, damage has already affected the sensorineural component, which will affect the hearing component of the patient and hence affect the quality of life. Therefore by using audiometry early detection of hearing loss in people affected with Type 2 Diabetes mellitus scan be done. It will help us to take early steps to make the patients affected by diabetes aware of the deafness and to take early measures for prevention and further progression of deafness.
