DIAGNOSING SINUS TENDERNESS

++

Eliciting sinus tenderness is important in the diagnosis and follow-up of sinusitis.

++

Firm pressure over any facial bone, particularly in the patient with an upper respiratory infection, may cause pain. It is important to differentiate sinus tenderness from non-sinus bone tenderness.

++
Method
++

  1. This is best done by palpating a non-sinus area first and last (Fig. 13.1), systematically exerting pressure over the temporal bones (T), then the frontal (F), ethmoid (E) and maxillary (M) sinuses, and finally zygomas (Z), or vice versa.

  2. Differential tenderness both identifies and localises the main sites of infection.

T (temporal) and Z (zygoma) represent no sinus bony tenderness, for purposes of comparison (F = frontal sinuses; E = ethmoid sinuses; M = maxillary sinuses)

DIAGNOSIS OF UNILATERAL SINUSITIS

++

A simple way to assess the presence or absence of fluid in the frontal sinus, and in the maxillary sinus (in particular), is the use of transillumination. It works best when one symptomatic side can be compared with an asymptomatic side.

++

It is necessary to have the patient in a darkened room and to use a small, narrow-beam torch.

++

Frontal sinuses

++

Shine the torch above the eye in the roof of the orbit and also directly over the frontal sinuses, and compare the illuminations.

++
Maxillary sinuses
++

Remove dentures (if any). Shine the light inside the mouth, on either side of the hard palate, pointed at the base of the orbit. A dull glow seen below the orbit indicates that the antrum is air-filled. Diminished illumination on the symptomatic side indicates sinusitis.

++

INHALATIONS FOR URTIS

++

Simple inhalations for upper respiratory tract infections (including upper airways obstruction from the oedema and secretions of rhinitis and sinusitis) can promote symptomatic relief and early resolution of the problem. The positive effect of making the patient responsible for active participation in management often helps to counterbalance the occasional disappointment when no antibiotic is prescribed.

++

The old method of towel over the head and inhalation bowl can be used, but it is better to direct the vapour at the nose.

++
Equipment
++

  • Container. This can be an old disposable bowl, a wide-mouthed bottle or tin, or a plastic container.

  • The inhalant. Several household over-the-counter preparations are suitable: e.g. Friar’s Balsam (5 mL), Vicks® VapoRub (one teaspoon), Euky Bear™, eucalyptus oil or menthol (5 mL).

  • Cover. A paper bag (with its base cut out), a cone of paper (Fig. 13.2a) or a small cardboard carton (with the corner cut away; Fig. 13.2b).
