“…Further, the range of visibility would increase when the Valsalva blowing gas pressed into the postcricoid space and pyriform sinus. Compared with the Ni et al study 4 , our work exposed the postcricoid space completely in 76% of the patients. This difference may be related to our different patient populations and the assessment method.…”

“…It is well known that the postcricoid space and the pyriform sinus is not easy to be displayed clearly by the fibre laryngoscope. Recently, the anterior cervical skin traction (ACST) 4 and modified Killian method (MK) 3 were considered to be an effective way of solving this issue. However, there is no investigation that facilitates the…”

“…Therefore, even with a fibre endoscope, tiny lesions on the postcricoid region may be ignored in patients. 2 Recently, both the modified Killian method combined with the Valsalva manoeuvre (V-MK) 3 and anterior cervical skin traction combined with the Valsalva manoeuvre (V-ACST) 4 were reported to facilitate access to the postcricoid region and pyriform sinus. However, it is unknown which of these approaches would be more appropriate in certain patients based on their specific condition and requirements.…”

“…Spraggs et al [5] performed valsalva manoeuvre to aid in the endoscopic hypopharyngeal examination and concluded superiority of this procedure compared to normal seated position. various other techniques have been advised from time to time to aid in the endoscopic visualization of the hypopharynx [6,8,11,12]…”

The more progress achieved in endoscopy, the more superficial cancers in head and neck region have been diagnosed. There are, however, some areas difficult to observe, particularly the hypopharynx, due to closure of this space. Examination of hypopharynx form an essential part of head and neck examination especially in the suspected malignancies as well as in the cases with unknown primary. As the flexible fiber-optic nasopharyngolaryngoscopy forms an essential part of examination of hypopharynx, the present study aims to evaluate the effectiveness of various manoeuvres devised to aid in better visualization of the hypopharynx. The present prospective study is an observation carried out on 30 patients, which had been followed up for hypopharyngeal or laryngeal disease, in the OPD of the department of Otorhinolaryngology and head and neck surgery in Gandhi Medical College and associated hospital, Bhopal, M.P. In the present study, authors compared the visibility of subsites of hypopharynx in 30 patients undergoing trans nasal flexible fibre optic endoscopy in normal seated position and with head torsion, valsalva manoeuvre and the Killian position. The authors concluded that the above mentioned manoeuvres facilitated the visualization of the entire circumference of the hypopharynx during endoscopic examination, are non invasive and easy to perform and so should be included as a part of routine examination while performing flexible fibre optic endoscopy.

“…During its evolution, many strategies have been described to optimise the view gained by the examiner . Many of these focus on improving the view of the hypopharynx due to the oncological importance of this site . However, as far as we are aware, there have been no reported techniques aimed at improving the view of the subglottis.…”
