Yankauer’s Ulcer: A Comprehensive Medical Guide

Overview

Yankauer’s ulcer (also called a posterior nasal ulcer or nasal septal ulcer in the context of chronic nasal suction) is a rare, localized erosion of the nasal mucosa that occurs secondary to prolonged or repetitive use of a Yankey‑type suction catheter (commonly used in otolaryngology, anesthesia, and intensive‑care settings). The lesion typically appears on the posterior aspect of the nasal septum or the turbinates where the tip of the suction device exerts constant pressure and friction.

Although historically described in surgical case series from the 1970s, modern reports indicate the condition remains uncommon, with an estimated incidence of 0.05–0.2 % among patients who receive continuous nasopharyngeal suction for more than 48 hours (Mayo Clinic, 2022). It most often affects:

• Critically ill patients in intensive‑care units (ICU) who require long‑term airway suction.
• Patients undergoing head‑and‑neck surgeries that necessitate intra‑operative suction.
• Individuals with chronic nasal obstruction who self‑administer suction devices (e.g., recreational “nose‑clearing” tools).

Because the ulcer forms deep within the nasal cavity, early recognition is essential to prevent secondary infection, septal perforation, or life‑threatening hemorrhage.

Symptoms

The clinical picture can be subtle at first, progressing to more obvious signs as the ulcer deepens. Common symptoms include:

• Local pain or burning sensation – often described as a “sharp” or “stinging” discomfort behind the nose.
• Nasal crusting or bleeding (epistaxis) – mild oozing may be intermittent; severe bleeding can occur if a vessel is eroded.
• Purulent or foul‑smelling nasal discharge – indicates secondary infection.
• Decreased sense of smell (hyposmia) or altered taste – due to mucosal disruption.
• Feeling of nasal obstruction – swelling around the ulcer can narrow the airway.
• Visible ulceration – on nasal endoscopy a circular or oval defect with a clean base may be seen.
• Fever or chills – only when infection spreads.

Causes and Risk Factors

Primary Cause

Yankauer’s ulcer results from mechanical trauma induced by:

• Continuous suction pressure (> 150 mm Hg) on the nasal mucosa.
• Friction from the rigid tip of a Yankey suction catheter.
• Inadequate lubrication of the catheter.

Secondary Contributing Factors

• Prolonged intubation or tracheostomy – patients often require frequent suctioning.
• Coagulopathy or antiplatelet/anticoagulant therapy – increases bleeding risk.
• Dry nasal mucosa – caused by supplemental oxygen, low humidity, or chronic rhinitis.
• Immunosuppression – e.g., chemotherapy, HIV, or chronic steroids.
• Pre‑existing nasal pathology – deviated septum, chronic sinusitis, or prior nasal surgery.

Diagnosis

Because the ulcer is deep‑seated, a systematic approach is required:

Clinical Examination

• History – duration of suction, type of catheter, and any recent surgeries.
• Anterior rhinoscopy – may reveal crusting but often misses posterior lesions.

Endoscopic Evaluation

Rigid or flexible nasal endoscopy is the gold standard. Findings typical of Yankauer’s ulcer:

• Well‑circumscribed mucosal defect (3‑10 mm) on the posterior septum or inferior turbinate.
• Granulation tissue at the margins and possible fibrinous exudate.
• Active bleeding points if vessels are involved.

Imaging (when needed)

• CT scan of the sinuses – to rule out adjacent bone erosion or abscess formation.
• MRI – rarely required; reserved for suspicion of deep soft‑tissue infection.

Laboratory Tests

• Complete blood count (CBC) – assess for anemia or leukocytosis.
• Coagulation profile – especially if the patient is on anticoagulants.
• Culture of nasal discharge – guides antibiotic therapy if infection is present.

Treatment Options

Management is multimodal, aiming to stop the mechanical insult, promote mucosal healing, and prevent infection.

1. Remove or Modify the Source of Trauma

• Switch to a low‑profile, soft‑tipped suction catheter.
• Reduce suction pressure to < 100 mm Hg when clinically feasible.
• Limit continuous suction duration; implement intermittent suction schedules.
• Apply a water‑based lubricating gel to the catheter tip before insertion.

2. Local Wound Care

• Saline irrigation – 2–3 L of isotonic saline daily to keep the area clean.
• Topical antiseptic ointments – e.g., mupirocin 2 % ointment applied twice daily.
• Barrier sprays – hyaluronic‑acid based sprays to maintain moisture.

3. Systemic Antibiotics (if infected)

First‑line choice based on likely pathogens (Staphylococcus aureus, Streptococcus pneumoniae, anaerobes):

• Clindamycin 600 mg PO q6h OR
• Amoxicillin‑clavulanate 875/125 mg PO q12h.

Tailor therapy after culture results. Typical course: 7–10 days (CDC, 2023).

4. Hemostasis and Surgical Intervention

• Chemical cautery with silver nitrate for superficial bleeders.
• Electrocautery or laser coagulation for larger vessels.
• Endoscopic debridement – removal of necrotic tissue and placement of a non‑adherent dressing (e.g., silicone sheet) if the ulcer is > 5 mm.
• In rare cases of extensive septal perforation, reconstructive septoplasty may be required.

5. Adjunctive Therapies

• Systemic steroids (e.g., prednisone 20 mg daily ≤ 5 days) can reduce edema but should be used cautiously in immunocompromised patients.
• Vitamin C (500 mg PO BID) and zinc supplementation may support mucosal healing.

Living with Yankauer’s Ulcer

Even after the ulcer begins to heal, patients often need to adopt daily habits to protect the nasal mucosa:

• Humidify inspired air – use a bedside humidifier set to 40‑60 % relative humidity.
• Saline nasal sprays – 2–3 times daily, especially in dry climates.
• Avoid nasal trauma – no forceful nose blowing; gentle dabbing with a soft tissue.
• Monitor for recurrence – keep a symptom diary; report new pain or bleeding promptly.
• Follow‑up appointments – endoscopic review every 2–4 weeks until complete re‑epithelialization.

Prevention

Because Yankauer’s ulcer is iatrogenic in most cases, prevention focuses on safe suction practices:

• Use low‑pressure suction settings whenever possible (≤ 100 mm Hg).
• Choose catheter tips made of soft silicone or polyurethane.
• Apply **lubricating gel** to the catheter tip before insertion.
• Limit continuous suction to ≤ 30 minutes before a brief pause to allow mucosal reperfusion.
• Implement **routine nasal care** in ICU patients: saline irrigation every 4 hours, humidified oxygen, and regular inspection of the nares.
• Educate staff and patients on the signs of early ulceration (pain, crusting, minor bleeding).

Complications

If left untreated or if management is delayed, several serious outcomes may develop:

• Septal perforation – permanent hole in the nasal septum leading to crusting, whistling, and impaired airflow.
• Secondary bacterial or fungal infection – can progress to cellulitis or, rarely, cavernous sinus thrombosis.
• Significant epistaxis – erosion of the Kiesselbach plexus or posterior nasal artery.
• Nasopharyngeal airway obstruction – swelling may compromise breathing, especially in patients with obstructive sleep apnea.
• Chronic nasal dryness and mucosal atrophy – long‑term discomfort and increased susceptibility to infections.
