A Clinical Study on Audiological Evaluation in Patients with Active Squamous Variety of Chronic Otitis Media Following Canal Wall Down Mastoidectomy with Ossicular Reconstruction

AbstractTo evaluate hearing results following canal wall down mastoidectomy with ossicular reconstruction for Chronic Suppurative Otitis Media of Active Squamosal variety&evaluate various factors related to surgery impacting hearing results. This prospective study involves 40 patients of active squamosal variety of chronic otitis media who attended ENT OPD and underwent canal wall down mastoidectomy with ossiculoplasty during the period from November 2014 to October 2015. All the patients were subjected to pre and 3  months post-op hearing assessment. Based on the hearing outcome, we expressed our study results into two groups, those with statistically significant improvement after surgery (T1) and those whose hearing got worsened or remained the same (T2). The mean post operative hearing gain of patients was 5.25 ± 7.30 dB, The median post-op hearing gain was 5.20 dB. Mean pre-operative hearing loss (AB gap) was 41.28 dB. Mean post-operative hearing loss (AB gap) was 36.24 with the average 3 months post-operative hearing gain was 5.2 dB, which reflects a definite improvement. There is a statis tically significant hearing improvement (with an average of 5.2 dB AB gap closure) following Canal Wall Down Mastoidectomy with ossiculoplasty as established in the study.

SiebertSummaryHearing represents the major sense in harbour porpoises (Phocoena phocoena) and impairment of hearing has a great impact on the survival of these animals. In this communication, some anatomical and histological aspects of the tympanoperiotic complex of harbour porpoises are presented. In addition, the ears of 21 incidentally bycaught or stranded freshly dead harbour porpoises of different age groups and sex were investigated histologically. At the entrance to...

AbstractEndoscopic tympanoplasty is a minimally invasive procedure and may be an alternative to conventional microscopic tympanoplasty with less operative time, producing similar graft uptake. Endoscopic tympanoplasty has a major disadvantage of single handedness which is overcome by a novel concept of “Two-handed technique” using Khan’s Justtach (endoholder). The aim was to study the outcomes of two handed endoscopic tympanoplasty in terms of graft uptake and hearing outcome. Two handed endoscopic tympanoplasty was performed in 20 patients with chronic suppurative otitis media between April 2018–Ap...

Outbreaks of severe pneumococcal disease occur sporadically and can affect large numbers of individuals, although they are less frequent compared to the pre-antibiotic era.1 The responsible pathogen, Streptococcus pneumoniae, is a Gram-positive bacterium that commonly colonises the nasopharyngeal tract, especially in young children. Occasionally, however, it can invade locally to cause mucosal infections including sinusitis, otitis media or pneumonia. Rarely, invasion of the bloodstream can lead to more serious infections, including septicaemia and meningitis.

Nontypeable Haemophilus influenzae (NTHi) efficiently colonizes the human nasopharynx asymptomatically but also causes respiratory mucosal infections, including otitis media, sinusitis, and bronchitis. The lipooligosaccharide (LOS) on the cell surface of NTHi displays complex glycans that mimic host structures, allowing it to evade immune recognition. However, LOS glycans are also targets of host adaptive and innate responses. To aid in evasion of these responses, LOS structures exhibit interstrain heterogeneity and are also subject to phase variation, the random on/off switching of gene expression, generating intrastrain ...

It rarely causes extrapulmonary complications, with otitis media and febrile seizures being the most common in children. Acute glomerulonephritis as a complication of H1N1 influenza virus infection has been described only sporadically.Herein we present a case of acute glomerulonephritis in a previously healthy...

In this study, we examine the relationship between developmental insufficiency of mastoid air cells and abnormal morphology of the paranasal sinuses in patients with chronic otitis media (COM) and acquired middle ear cholesteatoma (AMEC) using precise image assessment, in order to evaluate whether the anatomical features of paranasal sinuses has any impact on the pathogenesis in COM and AMEC.

Conclusion: Experience of early-life pain is seemingly associated with spinal pain in pre-adolescence. The study highlights that early-life painful experiences can influence programming future pain responses.What is Known:•Spinal pain in pre-adolescents is common, causes marked discomfort and impairment in everyday life, and may be an important predictor of spinal pain later in life.•Neurobiological mechanisms have been suggested as involved in early programming of pain sensitization.What is New:•Pain exposure in early postnatal life in terms of infantile colic and recurrent otitis media is associated with s...

Authors: Ono Y, Yoshikura N, Takekoshi A, Ohe N, Hayashi H, Yamada M, Hayashi Y, Kimura A, Shimohata T Abstract A 57-year-old woman with amyotrophic lateral sclerosis (ALS) receiving mechanical ventilation developed intractable right temporal headache. She was diagnosed with brain abscess secondary to chronic suppurative otitis media. In this case, the otitis media was caused by nasopharyngeal reflux associated with eustachian tube muscle weakness and a supine position. In addition, ALS patients under mechanical ventilation have a limited ability to convey their pain. Their complaints are often overlooked because m...

Impaired function of motile cilia causes failure of mucociliary clearance. Patients typically present with neonatal respiratory distress of unknown cause and then continue to have a daily wet cough, recurrent chest infections, perennial rhinosinusitis, otitis media with effusion, and bronchiectasis. Approximately 50% of patients have situs inversus, and infertility is common....

CONCLUSION: These results provide a representative sample of the current state of practices within many EDs across the United States for nonadmitted patients. A similar data reconstruction can be completed by other health systems to assess their prescribing practices in the ED to improve and elevate care for patients visiting the emergency room and treated as outpatients.
