Dysphagia Definition
• Difficulty in moving food from mouth to stomach.
• Swallowing: entire act of deglutition from placement of food in the mouth through the oral, pharyngeal and oesophageal stages of swallowing.
![Page 3: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/3.jpg)
Context
• Swallowing: complex process.
• Incidence: high in certain populationsEg elderly , CVA, GORD
• Associated with many different conditions.
• Huge impact on QOL.
• Important with relation to nutritional state.
• May indicate sinister pathology.

Stages of swallowing (Logemann)• Oral
Preparatory• Oral• Pharyngeal• OesophagealDuration &
characteristics of each phase depends on consistency and volume of food/drink taken.

Anatomy and physiology as part of the stages of swallowing
![Page 6: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/6.jpg)
Oral preparatory phase
• Food is manipulated in the mouth and masticated if necessary, reducing it to a consistency ready for swallow.
• Cranial nerves:– I: smell– V: Mandibular movement– VII: elevation of hyoid and tongue base– XI: tongue– XII: intrinsic & extrinsic tongue muscles
![Page 7: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/7.jpg)
Oral phase
• Tongue propels food posteriorly until untill the pharyngeal swallow is triggered.
• Cranial nerves:– V: soft palate elevation– VII: elevation of
tongue base– Accessory:soft palate,
tongue– Hypoglossal
![Page 8: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/8.jpg)
Pharyngeal phase
• Pharyngeal swallow is triggered and the bolus moves through the pharynx.
• Cranial nerves:– V: Elevation of larynx– VII: elevation of hyoid.– X: pharyngeal constrictors, cricopharyngeus,
vocal folds– XI: pharynx– XII: hyoid and larynx
![Page 9: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/9.jpg)
Oesophageal phase
• Oesophageal peristalsis carries the bolus through the cervical and thoracic oesophagus and into the stomach.

![Page 21: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/21.jpg)
Examination
• Full ENT examination– Ears (effusion, retratcted TM)– Nose (severe sinusitis, post nasal space
lesions)– Oropharynx (all mucosal surfaces)
• Visualisation of the larynx– Nasoendocopy and/ indirect laryngoscopy
![Page 22: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/22.jpg)
How to investigate?
• Sensation only with no risks:
? PPI and ?review
• Other factors (any)Ba Swallow or ‘Panendoscopy’
• These normal - reassure
![Page 23: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/23.jpg)
Investigations• Barium swallow • Direct
laryngopharyngooesophagoscopy
• OGD
If positive findings CT/MRI of neck.
• If neurological cause suspected/known refer to medical team.
![Page 24: DYSPHAGIA David Pothier MRCS DOHNS SpR ENT Louise Bredenkamp B Comm Path Speech Therapist.](https://reader033.fdocuments.us/reader033/viewer/2022061614/56649c9e5503460f9495d802/html5/thumbnails/24.jpg)
Imaging studies• Ultrasound: to observe tongue function and to measure oral transit times as well as the motion of the hyoid bone.
• Videoendoscopy: anatomy of oral cavity and pharynx, examine the pharynx and larynx before and after swallowing
• Videofluoroscopy: most frequent used technique in the assessment of oropharyngeal swallow.

manometry

• Exclude malignancy
• No organic cause –
try PPI, SpTp, reassure
• Organic cause
treat specific lesion
