We are sharing our experience of successful airway management in a patient with huge, fragile and vascular tonsillar mass, nearly obstructing the oropharynx. A 55-year-old male weighing 80 kg, American Society of Anaesthesiologists physical status-1 was admitted with a complaint of mass in oral cavity for the last 3 months. It was a tonsillar mass, arising from the right side and completely obstructing the airway, was painless, rapidly progressing and sometime bled on coughing and there was change in voice to nasal tone [Figure 1]. Airway examination revealed it to be Mallampati Grade 4, mouth opening was adequate with normal range of neck movement and mass moved with respiration. There was no history of obstructive sleep apnea. Computed tomography of the neck revealed isolated soft-tissue mass seen in the right tonsillar fossa projecting in the oropharynx occluding the lumen, adjacent vessels were normal. For airway management, flexible fiberoptic devices are of great help but due to their unavailability, we had planned to assess the airway through fiber optic flexible nasopharyngoscopy (6 mm karl storz) in the ENT department. Nasopharyngoscope was introduced from the left side of mouth showed normal vocal cord movement, epiglottis was large, hanging, and deviated to the left because of pressure effect of tonsillar mass. Nasopharyngoscopy was not possible through nose because mass was obstructing the nasopharyngeal passage. Informed written consent was obtained and preparations were made for emergency tracheostomy, if required. He was fasted for 6 h before surgery.
In the operation room after securing intravenous line and applying a monitor, baseline vital parameters were recorded. Oropharynx was anesthetized by 5 puffs of 10% lignocaine spray. He was preoxygenated for 5 min. Followed by administration of midazolam 1.5 mg, Fentanyl 2 μgm/kg intravenously. Inhalational induction was done with incremental increase in concentration of sevoflurane in 50% NO2 and 50% O2. We were able to ventilate the patient which was confirmed by visible chest rise and capnography. Succinylcholine 75 mg intravenously was injected for ease in the negotiation of the laryngoscope blade. The modified paraglossal technique was used for tracheal intubation with straight Miller laryngoscope blade from the left side. This facilitated us to negotiate narrow and straight laryngoscope blade in minimal available oropharyngeal space gently, shifting the pedunculated right tonsillar mass to the right, giving us just enough space to reach posterior to the epiglottis. Then, blade was lifted, Cormack Lehane Grade was 2b. Trachea was intubated with assistance of gum elastic bougie with internal diameter 7 mm of endotracheal tube and bilateral equal air entry was confirmed. Anesthesia was maintained with oxygen, nitrous oxide, sevoflurane, and vecuronium. Vital parameters were stable during intraoperative period. Trachea was extubated after reversal of neuromuscular blockade. His subsequent hospital stay was uneventful.
Large tonsillar mass in an adult is very rare. We had anticipated difficulty in mask ventilation after induction, difficult laryngoscopy from the right side with curved blade and chances of bleeding. That is why, we had introduced Miller blade from the left side. We had planned for inhalational induction keeping in mind obstructive symptoms of the patient, as fast intravenous induction might have caused airway obstruction due to loss of oropharyngeal tone. In the basic paraglossal technique of intubation, the straight blade is inserted in the extreme right corner of the mouth opening and advanced undervision paraglossal along the groove between the tongue and the tonsil until the epiglottis is visualized. Thereafter, the blade is passed posterior to epiglottis and lifted anteriorly, elevating the epiglottis to expose the glottis, and tracheal intubation is performed. The improved visualization is due to soft-tissue compression, due to narrowness of Miller blade and straight line of sight provided by straight blade ensures a continuous view of the larynx. The effectiveness of paraglossal technique over conventional approach in better glottic visualization and ease of intubation has a been reported by Jindal et al. and Anderson et al., Similar case of airway management in patient with tonsillar growth was reported by Agrawal et al. where authors have documented that paraglossal technique led to successful intubation in cases where Macintosh blade fails. To conclude that we must be well versed with different laryngoscope blade and techniques as selection of the right blade and the right technique can make difficult things easier.
