Rapid responses are electronic comments to the editor. They enable our users
to debate issues raised in articles published on bmj.com. A rapid response
is first posted online. If you need the URL (web address) of an individual
response, simply click on the response headline and copy the URL from the
browser window. A proportion of responses will, after editing, be published
online and in the print journal as letters, which are indexed in PubMed.
Rapid responses are not indexed in PubMed and they are not journal articles.
The BMJ reserves the right to remove responses which are being
wilfully misrepresented as published articles or when it is brought to our
attention that a response spreads misinformation.
From March 2022, the word limit for rapid responses will be 600 words not
including references and author details. We will no longer post responses
that exceed this limit.
The word limit for letters selected from posted responses remains 300 words.
Kahal & Malik reported that bleeding or airway obstruction may be
a complication of lingual thyroid.
Base of tongue swellings, such as lingual thyroid or lingual tonsil can be
a major challenge to airway management during anaesthesia.(1)
Standard techniques for airway control may be compromised. Direct
laryngoscopy with a McIntosh (curved) laryngoscope relies on placement of
the blade in the vallecula and base of tongue swellings interfere with
this. Additionally, these swellings may fragment or bleed following
instrumentation.
Use of laryngeal masks for airway control may not be successful.(2) Awake
fibreoptic intubation may be needed as "Plan A". Rescue techniques, "Plans
B and C" (such as cannula cricothyroidotomy or surgical airway) must be
part of airway management options.(3)
