1/19. Waldeyer's ring lymphoma presenting as massive oropharyngeal hemorrhage.A case report of a patient presenting with massive oropharyngeal hemorrhage originating from lymphoma of the tonsil and it's management is discussed. Locally advanced or recurrent squamous cell carcinoma may manifest with massive oropharyngeal hemorrhage, however, it is unusual for Waldeyer's ring lymphoma to present in this fashion. Management of oropharyngeal malignancies presenting in this manner includes airway control, control of hemorrhage, and biopsy of the tumor. hemorrhage control is provided by surgical exploration or intraarterial embolization. Extranodal lymphoma of the head and neck is not uncommon and is thoroughly discussed in the medical literature. hemorrhage into the upper aerodigestive tract is occasionally observed in the patient with head and neck cancer. It usually occurs, however, in patients with squamous cell carcinoma that have been previously treated or in patients with locally advanced cancers. A comprehensive review of the literature has revealed no other reports of head and neck lymphoma presenting with massive oropharyngeal hemorrhage.- - - - - - - - - - ranking = 1keywords = airway (Clic here for more details about this article) |
2/19. Hairy polyp of the oropharynx in a newborn: a case report.An unusual case of an oropharyngeal mass in a neonate causing intermittent airway obstruction during the first 24 hours following delivery is presented. This mass was confirmed to be a hairy polyp. We discuss the incidence, histology and peri-operative management of this unusual lesion.- - - - - - - - - - ranking = 14.133694225933keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
3/19. A patient with an epignathus: management of a large oropharyngeal teratoma in a newborn.An epignathus is an oropharyngeal teratoma composed of cells from ectodermal, mesodermal, and endodermal layers. Epignathi that arise from the palate or pharynx and protrude from the mouth result in life-threatening airway obstruction and usually cause asphyxiation shortly after birth. In our reported case, an antenatal ultrasound diagnosis allowed for preparation of an ex utero intrapartum treatment (EXIT) procedure. A tracheostomy was performed at birth with maternal-fetal blood flow still intact through the umbilical cord. Debulking of the large extraoral portion of the tumor, followed by complete intraoral resection, was performed. Masseteric function and swallowing slowly improved over several weeks. cleft palate repair is planned at 10 months of age. In the following report, the histology, classification, and pathogenesis of these "parasitic" tumors are reviewed.- - - - - - - - - - ranking = 14.133694225933keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
4/19. Bilateral tension pneumothorax following rigid bronchoscopy: a report of an epignathus in a newborn delivered by the EXIT procedure with a fatal outcome.We describe a case of a newborn baby with a prenatal diagnosis of an epignathus (oropharyngeal teratoma). With the potential for airway problems at birth, he was delivered by an elective EXIT (Extra Utero Intrapartum Treatment) procedure at 38 weeks of pregnancy. The airway was secured and rigid bronchoscopy performed. Initially he was stable, but developed cardiorespiratory difficulties 40 minutes after birth and died from a cardiac arrest 17 minutes later. Tension pneumothorax is a devastating complication that can occur with lower airway manipulation for anaesthesia and rigid bronchoscopy. The addition of positive pressure during mechanical ventilation converts the pneumothorax into a tension pneumothorax. The possibility of tension pneumothorax should be entertained in a mechanically ventilated patient whose ventilatory pressures are increasing, with diminishing cardiac output. A complicated case is presented, where the diagnosis was missed with a fatal outcome.- - - - - - - - - - ranking = 3keywords = airway (Clic here for more details about this article) |
5/19. Asymptomatic oropharyngeal lipoma complicating intubation.Oropharyngeal lipomas are rare tumours. We present the case of a young man with an asymptomatic lipoma almost completely occluding his supraglottic airway, found on magnetic resonance imaging (MRI) for a separate oral cavity lesion. Pre-operative anaesthetic assessment was undertaken because of the risk of airway obstruction at induction of general anaesthesia. We discuss the awake fibre-optic technique used for induction, as well as the treatment and follow-up of these tumours. This case highlights the need for formal anaesthetic assessment, in such cases, to avoid total airway obstruction at induction of general anaesthesia. It also emphasizes the extent of supraglottic obstruction that can be present without giving rise to any symptoms.- - - - - - - - - - ranking = 29.66009783716keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
6/19. Pre-anesthetic evaluation can play a crucial role in the determination of airway management in a child with oropharyngeal tumor.We experienced a case of a huge hemangioma occupying the oropharyngeal space in an 11-year-old child. Although urgent surgical tracheostomy under local anesthesia was suggested initially, medical interview and findings of computerized tomography and fiberoptic laryngoscopy revealed that the airway of the patient was relatively stable when she was in the semi-left decubitus position. General anesthetic induction would have had potential risks of airway obstruction. Thus, after placing the patient in the semi-left decubutus position, we chose semi-awake induction to secure the airway. With a small dose of fentanyl, we accomplished orotracheal intubation. In this report, we discuss the importance of referring to an airway management algorithm when encountering a difficult airway.- - - - - - - - - - ranking = 22.133694225933keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
7/19. Hairy polyp of the oropharynx. A case report with speculation on nosology.The hairy polyp of the oronasopharynx is a rare congenital malformation that has been classified as a dermoid, teratoid, teratoma, or hamartoma in the past. A case of oropharyngeal hairy polyp is presented that occurred in a male neonate with severe intermittent respiratory obstruction. The precise nosology of this unusual malformation is discussed, with the speculation that it is classified as a choristoma.- - - - - - - - - - ranking = 0.39270938529341keywords = obstruction (Clic here for more details about this article) |
8/19. The perioperative management of neonates with congenital oropharyngeal teratomas.Oropharyngeal teratomas are rare congenital neoplasms that distort orofacial anatomy and often cause respiratory embarrassment at birth. Immediate management of such lesions should include establishment of a secure upper airway, radiographic exclusion of midline central nervous system anomalies, and early surgical excision to prevent asphyxia or permanent disfigurement. Perioperative assessment and surgical management are reported for three oropharyngeal teratomas.- - - - - - - - - - ranking = 1keywords = airway (Clic here for more details about this article) |
9/19. Nasopharyngeal teratoma in the neonate.Nasopharyngeal teratomas are rare neoplasms, often presenting as neonatal airway obstruction. A case is presented of a full-term neonate with a mass which filled the oropharynx, nasopharynx and the entire left nasal cavity and extended through the left nares. airway obstruction necessitated orotracheal intubation immediately after delivery. cerebrospinal fluid rhinorrhea was suggested and computerized tomography was initially interpreted as a nasoethmoidal encephalocele. After a craniotomy failed to reveal a dural defect, the mass was completely removed via the nose and nasopharynx. The infant was extubated and had an uneventful recovery. This case illustrates the problem of confusing a teratoma for an encephalocele and demonstrates a pitfall in the interpretation of computerized tomography of these lesions.- - - - - - - - - - ranking = 1.7854187705868keywords = airway, obstruction (Clic here for more details about this article) |
10/19. Benign lesions of the nose, oral cavity, and oropharynx in children: excision by carbon dioxide laser.The carbon dioxide laser was used to treat a group of pediatric patients with benign lesions of the upper aerodigestive tract exclusive of the larynx. Prior to development of the CO2 laser, excision of these lesions by conventional means often resulted in incomplete removal, significant bleeding, and postoperative edema resulting in airway obstruction. The CO2 laser, with its unique properties of precise excision, hemostatic effect, and minimal postoperative edema, has become the instrument of choice in the removal of these lesions.- - - - - - - - - - ranking = 14.133694225933keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
