Mixed laryngocoele – case report and phoniatric aspects
Jarosław Markowski, Tatiana Gierek, Jarosław Paluch, Małgorzata Witkowska,

Introduction. Laryngocoele represents a saccular dilatation of
the larynx ventricule filled usually with air, less frequently with
mucous or purulent secretion. Laryngocoele is a rare larynx
pathology caused by increased intralaryngeal pressure.
Case report. The authors describe a rare case of mixed pneumolaryngocoele
in a 35-year patient. The primary symptoms
reported by the patient included hoarse voice, frequent throat
cleaning, sensation of lump in the throat, and effort/resting
dyspnoea increasing since several months. Physical examination
revealed a right side laryngeal sac bulge obturating laryngeal lumen
and completely covering the vocal fold, and a neck tumour
increasing during the Valsalva test. Patient’s voice was flat, without
neck muscle hyperfunction, and with normal activation of
supraglottic resonators. Phonation time was 20-second. Imaging
diagnostics (TK, NMR) was performed, as well as acoustic voice
analysis. The latter showed an increased strength of fundamental
tone and light noise component. The patient was operated by
an external approach. Images of larynx taken before and after
the surgery are presented. Surgical treatment of laryngocele
ensures permanent recovery. However, literature data show
that 4% of laryngocele cases are accompanied by cancer and,
therefore, prolonged follow-up is necessary.
