Understanding and Managing Nasal Scabs (Crusts)

The presence of dried masses of secretions, commonly referred to as nasal scabs or crusts, can cause significant discomfort and affect nasal function. These crusts can vary in nature and origin, often being associated with conditions like ozena (atrophic rhinitis), other forms of atrophic or subatrophic rhinitis, post-surgical states, or situations leading to excessive nasal dryness. Effective management involves what is often termed "cleaning of the nose," which primarily focuses on softening and gently removing these problematic crusts.

The Importance of Softening Nasal Crusts

Dry, adherent crusts in the nasal cavity must first be softened before attempting their removal. Attempting to forcibly remove dry crusts can traumatize the delicate underlying nasal mucosa, leading to bleeding, pain, and further irritation or infection. The principle behind softening is to rehydrate the crusts, making them less adherent and easier to dislodge.

A simple initial approach involves promoting a moist intranasal environment. If airflow through the nose is temporarily reduced (e.g., by gently placing cotton balls in both nostrils for 1-2 hours, ensuring breathing is not compromised), the natural nasal secretions may not dry out as quickly. The mucus accumulating between the surface of the mucous membrane and the crust can remain liquid, helping to loosen and push the crust away from the underlying tissue. After this specified period of increased local humidity, crusts that are not very tightly held may be easily dislodged by gentle nose blowing.

After a period of softening or increased intranasal humidity, nasal crusts that are not very adherent can often be easily expelled by gentle nose blowing. (Image illustrative of nasal crusts).

Techniques for Softening and Removal

Various methods can be employed to soften and remove nasal crusts:

• Moisturizing Agents:
  • Saline Solutions: Isotonic or mildly hypertonic saline nasal sprays or drops are fundamental for moisturizing the nasal passages and softening crusts. Regular use is often recommended.
  • Oil-based Preparations: Sterile emollient oils (e.g., olive oil, sunflower oil, sesame oil) or petroleum jelly can be gently applied to the anterior nares or instilled to soften crusts.
• Deep Tamponade (Historical/Cautious Use): A more potent traditional remedy involved a deep tamponade with twisted cotton balls. The cotton could be moistened with substances like hydrogen peroxide (a mild antiseptic and effervescent that can help loosen debris). The light pressure from such tampons was thought to reflexively induce a profuse secretion, further contributing to the separation of crusts. It was noted that cotton wool need not be wrapped around a threaded probe but could be inserted with a free hand. *Modern practice generally favors gentler, less invasive methods over deep packing for routine crust removal due to potential for mucosal trauma or discomfort.*
• Nasal Sprays and Lavage:
  • To quickly remove crusts, nasal sprays delivering a fine mist of saline or alkaline solutions can be used. The tube or nozzle of the spray is inserted into the nose. The sprayed liquid should be non-irritating. It is important to avoid harsh disinfectants that can adversely affect the delicate nasal mucous membrane.
  • Alkaline solutions (e.g., solutions containing sodium bicarbonate) or mineral water at room temperature can be applied. Nasal lavage or douching, as described for conditions like ozena (see section on Ozena treatment), can be effective. This involves a larger volume of fluid gently flowing through the nasal passages.

Cautions Regarding Nasal Irrigation

It is crucial to avoid using high-pressure irrigation methods like syringes or certain types of irrigators for routine crust removal, especially without proper technique or medical guidance. There is a significant risk of forcing fluid and potentially infected material into the Eustachian tube openings, which connect the nasopharynx to the middle ear. This can lead to complications such as otitis media (middle ear infection). Gentle, low-pressure methods like nasal rinse bottles or neti pots, when used correctly, are generally safer.

Attention! Do not use high-pressure devices like syringes or certain irrigators to remove dry crusts from the nasal cavity due to the potential danger to the ears (risk of otitis media) and other possible complications. Gentle, low-pressure methods are preferred.
