У пациентки после лечения рака в дыхательные пути попали два собственных зуба

Her Jaw Barely Opened After Cancer Radiation, and Two of Her Own Teeth Were Sitting in Her Airway A 65-year-old woman treated years earlier for squamous cell carcinoma of the oral cavity spent 15 days with fever, cough, and worsening breathlessness before anyone identified the cause. By the time she reached a hospital in respiratory distress, her oxygen saturation had fallen to 85 percent on room air and blood gas analysis showed type I respiratory failure. A chest radiograph pointed to her left main bronchus. Two of her own teeth had ended up in her airway. The case was presented at the American Thoracic Society's 2026 international conference by clinicians at Aster Whitefield Hospital in Bengaluru, India, and appears in the society's abstract supplement to the American Journal of Respiratory and Critical Care Medicine. The authors describe simultaneous aspiration of two teeth as exceedingly unusual, particularly in a patient whose airway had already been reshaped by cancer surgery and radiation. Fifteen Days of Fever Before Anyone Looked for a Tooth Her cancer treatment had been extensive: an extended glossectomy, a modified neck dissection, free flap reconstruction and adjuvant radiotherapy. The radiation left her with severe trismus, a restriction of mouth opening caused by damage to the muscles that work the jaw. Chest imaging showed an opacity in the left main bronchus with consolidation in the left lower lobe. Computed tomography showed a mild pleural effusion and hyperdense areas in both the oropharynx and the left bronchus, which the team interpreted as foreign bodies. She was stabilized with high-flow oxygen and broad-spectrum antibiotics before transfer for urgent removal. The authors flag a detail that runs against intuition. Teeth are radiopaque, yet they are not always visible on imaging. A tooth sitting quietly in a bronchus can be treated as pneumonia for weeks. Adults rarely inhale anything at all, which is part of why the diagnosis gets missed. In a single-center series of 25,998 bronchoscopies, only 65 procedures, roughly 0.24 percent, were performed because a clinician suspected an inhaled foreign body. A Locked Jaw Turned One Retrieval into Two Procedures Restricted mouth opening changed how the teeth could be reached. Clinicians could not pass instruments through the mouth, so they used nasal fiberoptic bronchoscopy and secured the airway with nasal intubation. The first tooth was found in the oropharynx. It was carefully maneuvered above the vocal cords and extracted. The second had lodged in the left main bronchus and could not be reached the same way. Retrieving it required a tracheostomy, with a Fogarty balloon and a snare used to dislodge the tooth and bring it out through the tracheostomy site. A follow-up bronchoscopy confirmed the airway was clear, her breathing improved markedly, and she was discharged for follow-up. The team framed the case as an argument for adaptable airway management, noting that the downstream risks include persistent pneumonia, granulation tissue in the airway, and respiratory failure. A recent review of airway foreign bodies in adults makes a related point. Management still lacks standardized clinical pathways, and although computed tomography performs well, with pooled sensitivity near 99 percent, a clean scan does not close the question when suspicion is high. Radiation Damages Teeth and the Muscles That Guard the Airway The mechanism connecting the two halves of this story is straightforward. Radiotherapy to the head and neck damages the salivary glands, bone, and soft tissues, increasing the risk of dental decay and tooth loss. The same radiation causes vascular injury and chronic inflammation that scar and stiffen the chewing muscles, producing trismus. Trismus is not a cosmetic complaint. A review of the condition sets the clinical threshold for mouth opening at below 35 millimeters in adults, with a normal range of 40 to 60 millimeters, and lists impaired airway clearance, increased aspiration risk, malnutrition, and poor oral hygiene among the consequences of the post-radiotherapy form. The same review describes clinical guidance as fragmented, with no single agreed diagnostic and management pathway. Put those together, and the abstract's warning becomes concrete. In head and neck cancer survivors, radiation-induced trismus and radiation-related dental damage raise the risk of loose teeth being aspirated, while simultaneously making the airway harder to inspect and harder to instrument. What the Authors Want Done Differently Their recommendation is unusually specific for a conference abstract. Early dental evaluation, they argue, is an essential strategy for heading off life-threatening events in this group. When loose teeth are found in a patient who has undergone head and neck radiotherapy, immediate removal by a dental professional is advised rather than watchful waiting. This is one patient, reported in a conference abstract rather than a peer-reviewed case report, so it establishes possibility rather than frequency. Estimates cited in the wider literature, including a case report on a long-retained airway foreign body, place the rate of adult airway foreign body aspiration at roughly 0.2 to 1.5 cases per 100,000 adults per year. What the case does suggest is where suspicion should sit. In a head and neck cancer survivor with limited mouth opening and pneumonia that will not clear, an airway foreign body belongs on the differential, and a normal-looking chest film should not end the search. Key Questions Answered What actually happened to this patient? She arrived with 15 days of fever, cough, and breathlessness and was found to have two aspirated teeth, one in the oropharynx and one lodged in the left main bronchus. Both were removed, and she recovered. Why did severe trismus make the case so difficult? Limited mouth opening blocked the usual oral route for instruments. The team used nasal fiberoptic bronchoscopy and nasal intubation, then needed a tracheostomy to reach the deeper tooth. Can an aspirated tooth really be missed on imaging? The authors caution that teeth are not always visible on imaging despite being radiopaque, which is one reason these cases can masquerade as recurrent or treatment-resistant pneumonia. Are head and neck cancer survivors at higher risk? The abstract notes that radiation-induced trismus and radiation-related dental damage raise the risk of loose teeth and subsequent aspiration in this group. That is a risk signal, not a prediction for any individual. How strong is this evidence? It is a single case in a conference abstract that has not undergone full peer review as a case report. It illustrates a hazard and a management approach rather than indicating how often it occurs. When should someone see a doctor? Persistent cough, fever, or breathlessness that does not resolve with treatment deserves evaluation, especially after head and neck radiotherapy. Anyone with sudden severe breathing difficulty should seek emergency care. Published by Medicaldaily.com
