A useful tool to analyze the effects of drugs, growth factors, and/or manipulated cells in an animal model of wound repair is described. This technique utilizes the properties of a polyvinyl alcohol (PVA) sponge to deliver and contain the desired treatment and also provide a platform to be excised and analyzed.

Nasal epithelial cells, obtained through superficial scrape biopsy of human volunteers, are expanded and transferred onto tissue culture inserts. Upon reaching confluency, cells are grown at air liquid interface, yielding cultures of ciliated and non-ciliated cells. Differentiated nasal epithelial cell cultures provide viable experimental models for studying the respiratory mucosa.

We describe here a method for biopsying olfactory mucosa from rat and human nasal cavities. These biopsies can be used for either identifying molecular anomalies in brain diseases or isolating multipotent adult stem cells that can be utilized for cell transplantation in animal models of brain trauma/disease.

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
FAQs
They support hemostasis through two related actions. First, the absorbent material takes up blood within the nasal cavity. As the sponge expands, or as it applies gentle pressure, it presses against nasal tissues and helps compress bleeding vessels. This combination can stabilize the affected area while limiting further movement of tissues during early care.
Expansion and gentle pressure provide localized support where bleeding occurs rather than relying only on external measures. Compression helps oppose the tissues around affected vessels, while absorption manages blood at the treatment site. The balance is important because the device must support hemostasis without creating unnecessary tissue disruption, particularly when nasal tissues are recovering after an intervention.
By remaining positioned against the affected nasal tissues, the device helps stabilize the area during recovery. This support can be useful after nasal surgery or trauma, when movement of the treated region may interfere with postoperative care. Their role therefore extends beyond immediate hemostasis to supporting a more controlled healing environment while the device remains clinically appropriate.
Placement should position the sponge within the nasal cavity so it can contact the affected tissues and provide the intended absorbent or pressure effect. Clinicians should also monitor the patient and the treated area after placement. Proper positioning and observation help maintain hemostasis, identify whether the area remains stable, and reduce avoidable tissue disruption during care.
Clinicians may use them after nasal surgery, following nasal trauma, or during episodes of epistaxis, meaning nosebleeding. The device can serve as a temporary treatment when bleeding control is the immediate priority, or it can support postoperative recovery when stabilization of the nasal tissues is needed. These uses connect emergency, surgical, and recovery-oriented care.
In emergency medicine, they provide localized support for controlling nasal bleeding and stabilizing the affected area. In otolaryngology, they can assist care after nasal procedures or injury, while perioperative teams may use them during postoperative recovery. Across these settings, their value comes from combining absorption, gentle compression, and monitored placement rather than from a single action alone.
