Due to the availability of antibiotics and advanced imaging techniques, the incidence and mortality of otogenic brain abscesses has reduced. Nevertheless, we still come across cases of otogenic brain abscess in modern times. Here, we report a case of the left ear chronic otitis media, squamosal type with intracranial complication of the left cerebellar abscess in a 14-year-old girl. Magnetic resonance imaging of the brain showed a thick-walled cystic lesion in the left cerebellar hemisphere measuring 41 mm × 28 mm × 26 mm suggestive of brain abscess. High-resolution computed tomography of the temporal bone showed soft-tissue density in the left mastoid air cells, in epitympanum, and mesotympanum encasing the left middle ear ossicular chain, suggestive of chronic otomastoiditis with possible underlying cholesteatoma. The patient underwent left retromastoid suboccipital craniotomy and excision of brain abscess followed by the left modified radical mastoidectomy 1 month later. Follow-up scan at 6 months showed no recurrence or any residual disease. Hence, timely surgical intervention for complicated chronic otitis media gives satisfactory results.","PeriodicalId":44304,"journal":{"name":"Indian Journal of Otology","volume":"28 1","pages":"181 - 185"},"PeriodicalIF":0.1,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49648008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, there is a need for early identification, evaluation, and management to reduce the morbidity. Objectives: The objective of the study was to describe etiologies of traumatic perforation of TM, to assess the findings of pure tone audiometry (PTA) among patients with traumatic perforation of TM, and to determine the outcome. Materials and Methods: This study was done between November 2017 and May 2019 in the department of ENT at Bangalore Medical College and Research Institute on 88 patients with traumatic perforation of TM who were subjected to otoscopic examination, tuning fork tests, and PTA. Patients were followed up on weekly basis. Results: Out of 88 patients, 33 patients (37.5%) were in the age group of 21–30 years. Fifty-four were males (61.36%) and 34 were females (38.63%). Slapping is the most common mode of injury with 50 (56.8%) patients. Left ear 55 (62.5%) was more commonly involved than right ear 33 (37.5%). Small perforation 55 (62.5%) was more common followed by medium-sized perforation 25 (28.4%) and large perforations were the least 8 (9.1%). Multiple quadrants were involved in 33 patients (37.5%). Posteroinferior quadrant was most commonly involved. Deafness (75%) was the most common symptom involving 66 patients. Average time taken for spontaneous healing was 37 days. Mean hearing improvement compared between hearing loss at the time of trauma and after 3 months was 13.18 ± 7.05 dB, which is statistically significant (P = 0.0001).

However, in the impaired auditory systems, this frequency resolution is affected, which indirectly leads to distortion in the perception of the sounds. However, the sharpness of tuning of a filter can be obtained from Q10 values and the shift in the tip frequencies of the psychophysical tuning curve can provide an estimate for the frequency resolution of the cochlea. Aim: This study aimed to estimate and compare the Q10 values and tip frequency between individuals with normal hearing and hearing loss. Subjects and Methods: A total of 92 ears were included for the study which was divided into two groups based on the hearing sensitivity. The psychophysical turning curves were obtained for 500 Hz, 1 kHz, 2 kHz, 4 kHz, and 6 kHz. The data on Q10 and the tip frequencies were statistically analyzed. Results: The results reveal that individuals with hearing loss have lesser Q10 values compared to individuals with normal hearing and this increased with increase in the test frequencies. Comparing the shift in the tip frequency between the two groups of individuals, the shift was toward the lower frequency which indicates it is an involvement of the outer hair cells. However, this study was limited only to those with mild flat sensory neural hearing loss. Conclusion: It could be concluded that Q10 and tip frequency measurement would be a valid measure for frequency resolution of the cochlea.","PeriodicalId":44304,"journal":{"name":"Indian Journal of Otology","volume":"28 1","pages":"126 - 129"},"PeriodicalIF":0.1,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70771167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Validated questionnaires for the same are robust alternatives when physical visits are not feasible such as the current COVID-19 pandemic and we present our findings of outcome assessment using COM outcome test (COMOT)-15 questionnaire through nonphysical mode. Materials and Methods: A retrospective analysis of a cohort of 112 patients of COM who underwent surgery by the single senior otology surgeon between 2009 and 2019 was done using COMOT 15 questionnaire through telephonic methods to circumvent the need of office visits. Results: Fifty out of 112 patients could be contacted and consented for the assessment and their COMOT-15 scores were obtained. The numbers of patients with any otologic symptoms and their need for consultations, except hearing loss were significantly less. One-third of the patients had mild to moderate residual hearing loss and its quality of life impacts, although the same neither was statistically significant nor required increased numbers of consultations. Conclusion: Bothering symptoms and the need for a frequent visit to the doctor is significantly less with adequate clearance of disease and mastoid obliteration in cases of canal wall down procedures. The residual mild-to-moderate hearing loss are not significant and manageable with day-to-day activities. Successful outcome of COM surgery needs long-term follow-up and evaluation by all practicing otologic departments and surgeons which can well be done through nonphysical modes in unprecedented situations like the current times.","PeriodicalId":44304,"journal":{"name":"Indian Journal of Otology","volume":"28 1","pages":"130 - 134"},"PeriodicalIF":0.1,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49159822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Short frenulum variations cause reduced anterior tongue movement resulting in breastfeeding, swallowing, articulation, and orthodontics problems. These abnormalities in infants cause breastfeeding problems that affect infants' weight gain, malocclusion, and speech disorders. Frenotomy in infant ankyloglossia is performed if there are problems with breastfeeding, poor sucking, slow weight gain, and recurrent mastitis. With this indication, we need to observed the efficacy of frenotomy done before the age of 1 month, and the frenotomy done at 1-3 months old in gaining weight of exclusively breastfed infants with ankyloglossia. Materials and Methods: A observational retrospective cohort method from patient medical records in a private hospital in Jakarta, Indonesia. The research subject is a total sampling patient medical records secondary data and collected 68 subjects. The Subjects are divided into two groups, the first group was patients whose frenotomy was done before the age of 1 month, and the second group was patients whose frenotomy was done at 1-3 months old. We assessed the weight gain between the two groups. The data were analyzed and compared the percentage of weight gain before and after frenotomy. Results: The percentage of weight gain before and after frenotomy shows that in the first group, there was a percentage gain of 11.4% in body weight of the subjects and during post-frenotomy control, the percentage of weight gain in this group increased to 111, 4%. In the second group, the percentage of weight gain before the frenotomy was 70.6%, while the post-frenotomy control was only 57.7%. Conclusion: The study demonstrated the efficacy of frenotomy in gaining weight of exclusively breastfed infants with ankyloglossia. There was a significant difference in the weight gain of infants with ankyloglossia who underwent frenotomy at the age of exclusive breastfeeding, before the age of 1 month and between the ages of 1 to 3 months.","PeriodicalId":44304,"journal":{"name":"Indian Journal of Otology","volume":"28 1","pages":"116 - 118"},"PeriodicalIF":0.1,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49538927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
