Hearing Aid Dispensing Training Manual - Second Edition

This text focuses on preparing US trainee hearing aid dispensers for their state practical exams, and the content is tailored to addressing the key assessment criteria. However, the basic topics covered are useful for hearing aid dispensers and potentially audiology...

Adjuvant intratympanic steroid therapy in sudden sensorineural hearing loss

Sudden sensorineural hearing loss (SNHL) means abrupt hearing loss by 30dB affecting three consecutive frequencies within 72 hours. This is treated by high tapering doses of systemic steroids, the role of which is controversial and fraught with possible complications in...

Cadaveric variation of nasolacrimal duct lateral nasal wall landmarks

Twenty mid-sagittal head sections of 10 fresh frozen cadavers were studied after removal of the nasal septum. This study showed that the most anterior projection of the middle turbinate head was noted to be anterior to the nasolacrimal duct in...

Outcomes after facial nerve preservation surgery for large vestibular schwannomas

Large vestibular schwannomas (Koos grade three or four) are traditionally treated by surgical resection. Gross total resection of such large tumours often results in facial nerve dysfunction. Hence facial nerve preservation surgery was introduced in which maximal surgical resection is...

Hydrogen peroxide and its uses in healthcare

This is an interesting review about the origin and uses of hydrogen peroxide, especially in neurosurgery. However, its uses are ubiquitous and applicable to several medical specialties. When hydrogen peroxide was first discovered in 1818 by Louis Thenard, it had...

Nasopharyngeal versus nasal swabs for COVID-19

This systematic review from Austria compares nasopharyngeal swab (NPS) and PCR test to nasal swabs from the other nasal areas with PCR. After finding 425 articles, using PRISMA guidelines 18 were deemed suitable for comparison. Anterior nasal swabs (ANS) and...

A safe and useful surgical procedure for allergic rhinitis?

Although the best management of allergic rhinitis is medical, intractable cases are not uncommon. Immunotherapy helps but is more practical if there is a single allergen involved. The authors compare the effects of submucosal inferior turbinoplasty alone with submucosal turbinoplasty...

Lingual tonsils and obstrucive sleep apnoea syndrome (OSAS)

Obstructive sleep apnoea can be due to narrowing of the retrolingual space by hypertrophic lingual tonsils. The authors studied 11 patients (five males and six females with a mean age of 44.3 years and a mean BMI of 28.6). All...

Centralisation of care for acoustic tumour surgeries?

Several factors are responsible for readmission after acoustic tumour removal. The authors retrospectively studied the association between hospital, patient and insurance factors with the rate of readmission following acoustic tumour removal in the United States using the Nationwide Readmission Database...

Acoustic schwannoma regression post-Gamma Knife treatment

In this retrospective study the authors studied the optimal interval following radiosurgery for differentiating between true growth of tumour versus pseudoprogression using serial volumetric data. A total of 118 patients with a median tumour volume of 0.74cm3 at Gamma Knife...

Zinc and rhinosinusitis

Patients with chronic rhinosinusitis (CRS) in general, and those with nasal polyps (CRSwNP) in particular, have been shown to have down-regulation of tight junction genes. Zinc, on the other hand, is well-known for its role in immune regulation and deficiency...

Paediatric nasopharyngeal carcinoma

Between 11 and 18% of nasopharyngeal carcinomas (NPC) occur in the paediatric age group but there are no specific management guidelines for this age group. Tunisia is a region with an intermediate incidence of NPC, the authors studied 40 cases...
