Q

Rhinosinusitis (bacterial)

A
  • bacterial infection usually follows URTI
  • pain over affected sinus and worse on leaning forward

Q

Oral Cancer - NICE 2WW red flags

A

Consider a suspected cancer pathway referral for oral cancer in people with either:

unexplained ulceration in the oral cavity lasting for more than 3 weeks or
a persistent and unexplained lump in the neck.

Consider an urgent referral for assessment for possible oral cancer by a dentist in people who have either:

a lump on the lip or in the oral cavity or
a red or red and white patch in the oral cavity consistent with erythroplakia or erythroleukoplakia.

Q

Head and Neck Cancer - diagnosis

Q

Nasopharyngeal Carcinoma

A
  • rare, but more common in Chinese
  • older and smokers
  • may present with nasal obstruction or polyp, unilateral glue ear or with 2ary neck lump. Otalgia
  • Ix flexible nasendoscopy of postnasal space, biopsy and MRI for staging
  • Mx: grommet insertion if glue ear
    MDT discussion and usually chemo + radio or in only selected refractory cases surgical resection

Q

Why can head and neck cancer present with ear pain?

A
  • tonsil area is supplied by glossopharyngeal nerve –> irriation lead to ear pain referred via Jacobson’s nerve
  • other causes of referred otalgia: irritation from nerves V, VII, IX, X, and cervical C2 and C3 - dental pathology, pharyngitis, TMJ pathology, sinusitis, cervical spine pathology, mumps, retro and parapharyngeal abscess

Q

Laryngeal cancer - features

A
  • commonly presents with hoarseness due to malignancy in larynx, or in chest (pancoast tumour pressing on recurrent laryngeal nerve) - for this reason CXR must be considered for a smoker with persistent hoarseness
  • sometimes can also get sho
  • tend to be SCC and associated with smoking/drinking
  • treatment is surgical excision with radio or chemo

Q

Idiopathic sensorineural hearing loss

A
  • sudden onset HL +/- tinnitus, no other abnormalities, otherwise fit and well
  • get bloods and MRI scan of internal auditory meatus (rule out serious causes e.g. acoustic schwannoma)
  • start PO steroids (intra-tympanic if poorly controlled diabetic or PUD)
  • treatment: hearing aids, +/- tinnitus rehabilitation therapy

Q

Otosclerosis

A

Replacement of normal bone by vascular spongy bone. It causes a progressive conductive deafness due to fixation of the stapes at the oval window. Otosclerosis is autosomal dominant and typically affects young adults. Increased risk of developing it during pregnancy

Onset is usually at 20-40 years - features include:

  • conductive deafness
  • tinnitus
  • normal tympanic membrane
  • positive family history

Management

  • hearing aid
  • stapedectomy

Q

Adenotonsillar hypertrophy and OSA in children

A

= large adenoids (tonsils)
Enlarged adenoids can become nearly the size of a ping pong ball and completely block airflow
- risk of developing OSA = child presents with hx of snoring, enuresis, wakes up tired and irritable
- how to approach this: OSA could be monitored with a pulse oximetry test. If this showed normal or mild symptoms monitoring would be appropriate. If the child is struggling to even eat and breathe at the same time due to nasal obstruction then adeno-tonsillectomy would be an appropriate consideration.
