ABSTRACT
A retrospective study of 174 patients with thyroid nodules who had preoperative fine needle aspiration biopsy (FNAB) evaluation and postoperative pathological results at Department of Otolaryngology, Faculty of Medicine, Chiang Mai University during the year 1992 to 2000. There were 139 females and 35 males. The most frequent age groups were 31 to 40 years in female and 51 to 60 years in male. The FNAB results were found to be malignancy in 17 patients (9.77 %), benign in 129 patients (74.14%) and suspicious for malignancy in 28 patients (16.09%). The final pathological results were thyroid carcinoma in 33 patients (18.97%) and benign nodule 141 patients (81.03%). By analysis the preoperative FNAB and final pathological results, the sensitivity, specificity and accuracy of FNAB were 82.35, 86.78 and 87.86 percent respectively. The results confirm that FNAB is very useful in management of thyroid nodule by detecting malignancy and decrease the unnecessary operation. Chiang Mai Med Bull 2002;41(1):51-57.
ABSTRACT
gained widespread acceptance. This study presents one case of a skull base defect after the resection of esthesioneuroblastoma. A 19-year-old man patient with a history of recurrent epistaxis was evaluated by endoscope and esthesioneuroblastoma of the right cribriform area was identified. The tumor was resected endoscopically and the skull base defect repaired by a combination of septal cartilage, temporal fascia and mucosal grafts. The septal cartilage free graft was placed above the anterior cranial fossa. This cartilage free graft served as a new framework for the anterior cranial fossa defect, which prevented a leakage of cerebrospinal fluid. The temporal fascia graft was put above the anterior cranial fossa, but beneath the septal cartilage graft in order to help mucosal migration during the healing period. After a six month postoperative period, there was neither evidence of CSF leakage nor a recurrence of the tumor. An endoscopic approach provides a safe and effective means for repairing the anterior skull base defect in selected cases.Chiang Mai Med Bull 2001;40:(3):155-161.
