Objective: To discuss the feasibility and superiority of lateral thyrotomy approach on the paraglottic space operation.
Method: Five case mucocele of larynx located at paraglottic space were resected the cyst completely by a U-shaped lateral thyrotomy approach. One cases of laryngeal trauma foreign body in paraglottic space was taken out by approach through vertical split of the thyroid lamina.
Result: Three cases mucocele of larynx located did not recurrent during follow-up 1 year and their phonation were recoverd normally. The other two cases are during follow-up. One cases of laryngeal trauma foreign body has been oprated, her vocal cords moved normally and the glottic could be closed completely.
Conclusion: Through lateral thyroid lamina split or partial resection approach, the paraglottic space can be exposed clearly and the cyst or foreign body can be easily removed under direct visualization. The operation provides minimal trauma without deformity in laryngeal framework, and postoperative complication to enter the laryngeal mucosa. It proves to be an effective approach to benign lesion at paraglottic space.
