Abstract: 【Abstract】〓Objective〓To summarize the clinical experience of endoscope-assisted styloidectomy via postauricular incision and the anatomic landmarks of styloid process location. Methods〓Ten patients with Eagle's syndrome underwent surgery from January 2012 to August 2013,and the surgical procedure was performed by endoscope-assisted styloidectomy via postauricular incision. Results〓The important anatomic landmarks of endoscope-assisted styloidectomy via postauricular incision included posterior border of parotid,anterior border of the sternocleidomastoid muscle and posterior belly of digastric muscles..All patients were successfully located and truncated styloid process by serially exposed these anatomic landmarks mark. Incision length was 2.1±0.5 cm. The operative time was 54.5±11.7 min. Amputation length of styloid process on left side was 2.8±0.8 cm and 2.6 ± 0.7 cm on the right side. In 10 patients, 7 patients' symptoms were completely relieved, 2 patients' symptoms were improved and 1 case had no obvious relief. No recurrent case was found in 12.1±4.5 months of follow-up. One case had ear numbness on one side after surgery for 3 months and no case suffered facial paralysis. Conclusion〓Endoscope-assisted styloidectomy via postauricular incision is a effective, minimally invasive and postoperative appearance procedure. Precisely located styloid process need to serially expose the anatomic landmarks, such as endoscope-assisted styloidectomy via postauricular incision included posterior border of parotid, anterior border of the sternocleidomastoid muscle and posterior belly of digastric muscles. Followed these procedures would help to increased the operation quality and be benefit for patients with Eagle's syndrome.
