Red Flags in ENT

Presentation Overview

  • Presenter: Melville DeCruise, ENT Surgeon at Westmead Hospital and the University of Sydney.

  • Collaborator: Larry Kalish, ENT Surgeon at the University of Sydney at Concord Hospital.

  • Focus of Lecture: Red flags in ENT (Ear, Nose and Throat).

Definition of Red Flags

  • Red flags are clinically recognizable signs and/or symptoms indicating potentially serious underlying problems within the ENT system.

  • Importance:

    • Immediate recognition is crucial to avert disease progression.

    • Ignoring these signs may lead to poorer long-term outcomes for patients.

Areas Covered in ENT Red Flags

  1. Otolaryngological System (ear)

  2. Sinonasal System (nose and paranasal sinuses)

  3. Larynx and Pharynx (throat, head, and neck)

The Ear

Basic Anatomy of the Ear

  • Divisions:

    1. External Ear:

    • Composed of the pinna, external auditory canal.

    1. Middle Ear (Tympanum):

    • Includes the tympanic membrane, air-filled middle ear space, eustachian tube, middle ear ossicles, facial nerve, parts of the labyrinth (balance organ), and nerve of taste.

    1. Inner Ear:

    • Consists of the cochlea and semicircular canals.

    • Functions in sensorineural hearing and balance; connected to the brainstem via vestibular and cochlear nerves.

Otoscopic Examination

  • Evaluates the external auditory canal and tympanic membrane.

  • Key Observations in Tympanic Membrane:**

    • Annular Ligament and Sulcus:

    • The thickened white structure at the drum margin anchoring it to bone.

    • Handle of the Malleus:

    • Structures visible through the translucent drum indicating connectivity to the middle ear.

    • Light Reflex:

    • Cone of light that appears on normal drums, altered in pathology.

  • Dynamic Examination:

    • Patient may perform Valsalva maneuver to assess middle ear fluid status.

Ear Disease Manifestations

  • Swelling in Pinna or External Auditory Canal:

    • Must observe the connection and structures behind the pinna.

    • Inflammation from infections can obliterate the postauricular sulcus, especially in mastoiditis.

  • Red Flags:

    • Symptoms like tinnitus, hearing loss, and ear discharge necessitate urgent attention.

Acute Suppurative Otitis Media

  • Common Condition:

    • Often follows upper respiratory infections.

  • Symptoms:

    • Severe ear pain, hearing loss.

  • Otoscopy Findings:

    • Bulging drum, evidence of erythema, loss of translucency.

  • Treatment:

    • Observation and antibiotics if necessary.

  • Complications:

    1. Perforation of Eardrum - leads to pain relief but must be observed.

    2. Tympanosclerosis - long-term complication, calcification of the drum.

    3. Acute Mastoiditis and Facial Nerve Neuritis:

    • Red flags requiring urgent assessment.

    • Symptoms: increased postauricular pain, swelling, changes in drum morphology, and facial muscle weakness.

Inner Ear Infections

  • Key Symptoms:

    • Sudden profound hearing loss, dramatic rotatory vertigo.

  • Evaluation:

    • Must consider intracranial infections which may extend to meningitis.

    • Patients at risk: Young children and elderly, those with comorbidities.

Sinonasal System

Anatomy Overview

  • Structures:

    • Nose, nasal cavity, paranasal sinuses, divided by nasal septum and turbinates.

  • Examination Tools:

    • Nasal speculum and headlight for visualization.

Foreign Bodies in Nasal Cavity

  • Commonly affect children; button batteries can cause severe burns.

  • Requires urgent removal, typical signs of toxic effects must be watched for.

Sinusitis and Complications

  • Typically follows upper respiratory infections.

  • Persistence of unilateral symptoms needs imaging and endoscopy.

  • Red Flags:

    • Unilateral pathology with bleeding or bone erosion on CT.

  • Specific Cases:

    • Consider inverted papilloma as a cholinergic neoplasm.

Larynx and Pharynx

Importance of Anatomy

  • Integrally related to swallowing and respiration; compromised function signals urgent intervention.

Red Flags in Throat Pathologies

  • Key Signs:

    • Sudden changes in breathing sounds (stridor).

  • Causes of Stridor:

    1. Foreign Body Aspiration.

    2. Infections like epiglottitis: Requires urgent care; characterized by drooling and stridor.

  • Other Infections:

    • Ludwig's angina resulting in swelling and airway risk; requires antibiotic therapy.

Tonsillitis vs Peritonsillar Abscess

  • Common Tonsillitis - usually bilateral pain and obvious pustules.

  • Peritonsillar Abscess - unilateral severe pain, trismus. Needs urgent drainage and antibiotics.

Persistent Hoarseness

  • Associated with potential for malignancy; especially with smoking history.

Foreign Bodies in Upper Alimentary Tract

  • History of ingesting food with bones; requires urgent assessment for extraction.
