A male full-term vaginally delivered infant born of a non-consanguineous
marriage to a primi mother was brought to the referral hospital on day
25 of life with complaints of noisy breathing and respiratory distress
since last 15 days. On clinical examination the baby had stridor, supra
sternal/subcostal retractions, and tachypnea suggestive of upper airway
obstruction. The infant was maintaining oxygen saturation in room air.
Rest of general and systemic examination was normal. Direct
laryngoscopic examination by ENT surgeon revealed presence of a
vallecular cyst with epiglottis falling on glottic opening due to its
pressure effect producing a supraglottic obstruction and stridor in the
neonate. The findings were reconfirmed by fibreoptic endoscope. The cyst
was excised using CO2 laser under direct laryngoscopy; this was followed
by epiglottpexy. Histopathological examination revealed cyst wall partly
lined by squamous cell and partly by respiratory epithelium. The cyst
wall showed presence of chronic inflammatory cells along with fibrosis.
The gross impression was of laryngeal vallecular cyst of saccular type.
Post-operative follow-up was un-eventful.
Vallecular cyst (VC) is a rare cause of stridor in
the neonatal age group(1). Vallecular cyst is usually benign in nature
and presents in early infancy with stridor, respiratory distress and
airways obstruction(1-3). Infants with vallecular cyst can have
interrupted feeding due to distress which may lead to 'failure to
thrive(1,2). Laryngomalacia is a common association(1-3). Antenatal
diagnosis using ultrasound scan at around 28 wks gestations is possible
which may help clinician to plan for a high risk delivery at a tertiary
care center where facilities for emergency tracheostomy or surgery and
ventilation of neonate are available(4). Postnataly diagnosis can be
made by direct laryngoscopy with careful observation of the base of
tongue(3). A fibreoptic endoscopic review of upper airway and bronchus
is mandatory to rule out other causes of obstruction and associated
laryngo/bronchomalacia(1,3). Excision of cyst with or without corrective
surgery for laryngomalacia depending upon the severity grade is the
treatment of choice(3).
