title: Tongue base reduction with hyoepiglottoplasty for the treatment of severe OSA.
abstract: Surgical treatment for retro-lingual obstruction in patients suffering from obstructive sleep apnea syndrome remains a problem for which there is no simple solution. The techniques most in use (tongue suspension, genioglossal advancement with hyoid suspension) are effective primarily as stabilization methods modifying neither tongue position, nor volume and only produce appreciable results when performed on non-overweight patients with respiratory disturbance index <40. For patients suffering from severe obstructive sleep apnoea syndrome in whom the most obvious morphological alteration is the presence of hypo-pharyngeal obstruction due to tongue base hypertrophy, who are overweight or suffering from moderate obesity, a surgical procedure aimed at reducing tongue volume and at repositioning the hyoid bone, even if invasive, leads to a favourable outcome. Herein, personal experience is described in a group of 8 patients presenting severe obstructive sleep apnoea syndrome incompatible with normal quality of life and normal life expectancy (mean respiratory disturbance index = 55.1) who underwent surgical resection of the tongue base with hyoepiglottoplasty. This technique, first described by Chabolle, differs radically from others inasmuch as it guarantees enlargement of the hypo-pharyngeal lumen and remodelling of the hyolingual complex. Using a suprahyoid cervical approach, it is possible to effect ample reduction of the tongue base with amplification of the hypo-pharyngeal airway without inducing problems as far as concerns either swallowing or speech.
