Objective:
To evaluate the surgical technique and efficacy of the resection of parapharyngeal space neoplasm via styloid diaphragm approach.
Methods:
Thirty-three cases underwent the resection of parapharyngeal space tumors via styloid diaphragm approach from Jan 2005 to Jan 2011 were reviewed. Of the cases, 28 were with benign tumors treated by surgery alone, and 5 were malignant tumors treated by surgery plus postoperative radical radiotherapy.
Results:
The parapharyngeal neoplasms in all cases were completely resected via styloid diaphragm approach. The postoperative follow-up ranged from 13 months to 7 years (median = 4.6 years). No tumor recurrence was found in 30 cases, but 3 cases experienced tumor recurrence, including 1 chondrosarcoma (3 years after surgery and chemoradiotherapy), 1 chordoma and 1 adenoid cystic carcinoma (5 years after surgery and radiotherapy). Severe postoperative complications were not observed, but 2 cases showed mild mouth askew and fully recovered after 3 months, and 1 case was complicated with hoarseness and cough symptoms that disappeared after heteropathy.
Conclusion:
Resection of parapharyngeal neoplasms via styloid diaphragm approach is an ideal surgical technique, with well-exposed surgical field, less tissue injury, and less postoperative complication.
