Purpose of Review
When persistent postural-perceptual dizziness (PPPD) entered the diagnostic nomenclature in 2017, treatment options were adopted from its predecessors, including use of vestibular rehabilitation, psychotherapy, and serotonin reuptake inhibitors. Individualised treatment may require additional interventions to cover the full range...
Background:

A prospective case series and cost analysis were conducted at a...
Patients and parents in particular can find the decision regarding which device to have implanted difficult due to the amount of often complicated information that is available. The desire to choose the 'right' implant for themselves or their child takes on great importance due to the finality of the procedure. There is some evidence that certain p...

Furthermore, ENT emergencies can be rapidly life-threatening and may necessitate systematic and multidisciplinary management and resuscitation. We aimed to develop a prac...
CWU and CWD surgery for cholesteatoma both have advantages and disadvantages; CWD surgery with primary obliteration aims to deliver to the patient the advantages of both. Using Kaplan-Meier survival analysis, the probability of residual cholesteatoma after 5 years was 3.5% (95% CI: 1.3%-9.3%), representing four residual cholesteatomas; there were n...

Background: Nasal packing is often used after functional endoscopic sinus surgery
(FESS). Variousnon-absorbable agents are used but these packs can be uncomfortable
and cause pain and bleeding on removal. Increasingly, biodegradable nasal packs are
being used and have shown promising effects on post-operative bleeding and healing
after FESS.
Aim: W...
ENT presentations are common both in primary care and accident and emergency departments. Unfortunately, many clinicians are not comfortable handling ENT emergencies due to a lack of knowledge and skill stemming from an undergraduate level onwards. An 'Introduction to ENT' course has been cited as an answer to bridge the gap in knowledge and promot...
