Ischemic necrosis of the tongue following transoral neurosurgical procedure
نویسندگان
چکیده
Introduction: Postoperative, lingual swelling and necrosis are unusual complications that can lead to life-threatening airway obstruction. We report a case of bilateral ischemic necrosis of the tongue following transoral neurosurgical procedure. Observation: A Davis-Boyle mouth gag was used for tumor exposition and the operation lasted 8 h. At the end of the surgery, we noticed a bluish discoloration with a mild edema of the tongue. The patient had kept intubated in a monitored setting and intravenous steroids were administered. However, the edema increased and necrosis of the tongue appeared 72 h after the surgery. The patient underwent tracheotomy and the necrotic tissue was removed. More than 15 days passed before glossal engorgement resolved. Discussion: The etiology of tongue necrosis is likely related to tissue ischemia, secondary to venous or arterial obstruction. Prolonged use of the Davis-Boyle mouth gag may incur greater risk of ischemic necrosis of the tongue. Résumé – Nécrose ischémique de la langue après une intervention neuro-chirurgicale trans-orale. Introduction : Après une intervention chirurgicale, l’œdème et la nécrose de la langue représentent une complication rare qui peut entraîner une obstruction des voies aériennes mettant en jeu le pronostic vital. Un cas de nécrose ischémique bilatérale de la langue après une intervention neuro-chirurgicale trans-orale est rapporté. Observation : Un ouvre-bouche de Davis-Boyle a été utilisé pour aborder la tumeur et l’intervention a duré 8 h. À la fin de l’intervention, la langue présentait une couleur bleuâtre et un œdème modéré. La patiente a été gardée, intubée, dans l’unité de soins intensifs et des corticoïdes ont été injectés par voie intra-veineuse. L’œdème a augmenté et une nécrose de la langue est apparue 72 h après l’intervention. La patiente a été trachéotomisée et le tissu nécrotique excisé. L’œdème lingual a régressé en une quinzaine de jours. Discussion : La nécrose linguale est probablement due à une ischémie tissulaire, secondaire à une obstruction veineuse ou artérielle. L’utilisation prolongée de l’ouvre-bouche de Davis-Boyle augmente probablement le risque de nécrose ischémique de la langue.

Ischemic necrosis of the tongue in surgical patients with septic shock: a case report
BACKGROUND As the tongue is a well-vascularized organ, ischemic necrosis of the tongue is a rare disease entity. Critically ill patients with profound shock may experience end-organ hypoperfusion, which might result in tongue necrosis. However, to our best knowledge, there are no reports regarding ischemic necrosis of the tongue in surgical patients with septic shock. CASE PRESENTATION Two pa...

Polymorphous low-grade adenocarcinoma is a rare malignancy arising from the minor salivary glands in the aerodigestive system, most frequently the hard palate. The treatment of choice is wide surgical resection, and the efficacy of radiotherapy has not been confirmed. A 54-year-old male presenting with a mass at the base of the tongue performed transoral laser microsurgery. The pathologic diagn...

In recent years, transoral robotic surgery (TORS) has been used for the removal of pharyngeal and laryngeal cancers with the objective to improve functional and aesthetic outcomes without worsening the survival. This prospective single-centre cohort study described TORS in selected tumours of the tongue base in order to assess safety, efficacy and functional outcome of the procedure. From Octob...
متن کاملTransoral Resection of Giant Parapharyngeal Space Tumors via a Combined Surgical Approach
Introduction: Parapharyngeal space (PPS) tumors account for 0.5% of the head and neck neoplasms. Based on the evidence, 80% of these tumors are of a benign nature. Surgical excision is the treatment of choice for this condition. The present study was conducted to propose transoral resection as an efficient way to excise the benign well-defined tumors of the PPS. Materials and Methods: Thi...
