Barbed Suspension Bridge Pharyngoplasty: Introducing a Novel Technique for Barbed Pharyngoplasty.

Surgical management of Obstructive Sleep Apnea (OSA) and Snoring has undergone many major and minor changes over a period of last decade. The most common surgical approach for OSA is uvulopalatopharyngoplasty (Stuck et al. in Sleep Med 50:152-165, 2018). The main goals of treatment of OSA are to decrease the risk of deleterious health effects and improve quality of sleep (Evans et al. in Otolaryngol Clin North Am 53: 319-328, 2020). Since bimanual surgical techniques in the depth of oral cavity have been tricky, search for a less demanding & easy to learn technique is always on. The surgical technique should also provide long term results with manageable complications. Barbed suture has been in sporadic use for the last decade amongst sleep apnea surgeons for its advantage of knotless application and distributed suture tension. However, the barbed suture which has been used is absorbable and is used only to close the surgical wound on the soft palate. In this paper we are describing our technique of using the 3-0 Polybutester non absorbable barbed suture to perform a novel technique of palatal surgery, in which we suspend the lower part of the soft palate permanently as a suspension bridge between the right and left Pterygomandibular raphae, so that the lower part of the soft palate cannot move posteriorly to touch the posterior pharyngeal wall preventing airway obstruction whereas it can still move superiorly freely while swallowing or during phonation. This technique can prove to be a technically less demanding one which provides excellent long-term results in snoring and OSA with manageable complications.
