Historical Article[History of the ear speculum. Images from the history of otorhinolaryngology, highlighted by instruments from the collection of the German Medical History Museum in Ingolstadt].
BACKGROUND. Inspection of or interventions in the external ear canal and the nostrils pose similar technical problems. This is the reason why early instruments devised for otoscopy and rhinoscopy were based on an identical principle. ⋯ It was the first device to incorporate interchangeable ear specula, illumination by a perforated mirror, and a magnifying lens into one handy instrument. It is the precursor of the modern diagnostic sets comprised of a battery-handle, various specula, and accessories for otoscopy, rhinoscopy, and ophthalmoscopy which started to come into use in the late twenties of this century. This historical development of the ear specula is described and illustrated in detail.

[Short tau inversion recovery fat suppression in T2-weighted turbo spin echo-MRI of malignancies of the mouth and oropharynx].
T1-weighted sequences before and after the application of contrast medium and T2-weighted sequences are used for magnetic resonance imaging of malignomas of the oral cavity and the oropharynx. The authors studied the utility of short tau inversion recovery fat suppression (STIR) in T2-weighted turbo spin echo sequences (TSE). ⋯ The STIR technique is beneficial for the progress in diagnostic imaging of cancer of the oral cavity and oropharynx.

An 86-year-old man presented ambulatory with acute dysphagia. Radiologic examination and endoscopy revealed a swallowed postauricular hearing aid. The earmold of the hearing aid became visible in the hypopharynx after mucus and saliva were removed. ⋯ The postoperative phase was uneventful with normal swallowing and discharge. Technical inspection revealed that the hearing aid no longer worked. Diffusion of toxic substances (zinc, mercury) from the impacted batteries is not to be expected.

[Computerized manometry concept for site-specific reconstruction of the pharynx and pharyngo-esophageal transition].
Fifty-three patients who underwent laryngopharyngeal cancer surgery were examined with a sequential computer manometry system using 4-channel pressure probes. Swallowing coordination is largely independent of the oropharyngeal pressure thrust nor of the pharyngeal transit time and depends mainly on initiation of swallowing. The points of interest are the pharyngeal entrance and outlet. ⋯ For that purpose we modified the myofascial pectoralis-major-flap. It covers defects where a soft lining is required. The resistance to bolus flow is reduced, alleviating the need to increase the driving force of the tongue which would otherwise increase to compensate for the defect.
