Physical examination revealed good oral hygiene, a pedunculated left-sided soft palatal mass ~4 x 5 cm ulcerated on the medial surface, touching the tongue base and faucial pillars
on the ipsilateral side but not attached to them.
Pre-anaesthetic examination showed morbid obesity (body mass index of 40), a relatively narrow mouth with a large tongue, complete dentition and prominent faucial pillars
and soft palate, contributing to a Mallampati score of 3.
examined the different sensory modalities that have been used to stimulate the anterior faucial pillars at the posterior oral cavity, when applied alone and in all combinations, and to record SM-EMG activity .
Effects of mechanical, cold, gustatory, and combined stimulation to the human anterior faucial pillars.
On examination with a Jackson laryngoscope, there were no mucosal abnormalities, but a generalized fullness of the left piriform sinus and vallecula was observed, as well as some fullness of the lingual tonsils and faucial pillars
In addition, scar contracture at the posterior border of the soft palate can create a "curtain" effect, pulling the soft palate downward against the tongue and causing significant transverse narrowing between the posterior faucial pillars
, further contributing to OSA.
