[Specialization in thyroid surgery].
OBJECTIVE: To evaluate the results of surgically treated patients with benign thyroid disorders from Department of Otolaryngology- Head and Neck Surgery. METHODS: The clinical data of 496 patients operated for benign thyroid disorders were retrospectively analyzed in this department from January 2001 to April 2004. The incidence of complications, particularly postoperative permanent recurrent laryngeal nerve palsy and hypocalcemia, duration of surgery, incision length on the neck, hospitalization days and postoperative recurrence were evaluated. RESULTS: Unilateral total thyroidectomy with contralateral partial lobectomy was performed in 314 cases, unilateral total thyroidectomy with isthmectomy in 76, bilateral subtotal thyroidectomy with the remnant left at the upper pole in 29, isthmectomy in 3, total thyroidectomy in 46. The operations on 28 patients with substernal goiter have been successfully performed via cervical collar incision. Of these patients, the incidences of unilateral recurrent laryngeal nerve paralysis and temporary postoperative hypocalcemia were 0.2% (1/496) and 1.8% (9/496), respectively. There were no bilateral vocal cord paralyses and permanent hypocalcaemia. Postoperative hemorrhage requiring reoperation occurred in 3 cases (0.6%). No patients had incision infection. The mean duration of surgery was 66 min. The mean incision length on the neck was 5.2 cm. The incidence of postoperative recurrence was 0.2% (1/496). The mean hospitalization day was 6.3 d. CONCLUSIONS: Otolaryngologists who had received stringent training of head and neck surgery seem to have the advantage to avoid injury of recurrent nerve in the thyroid surgery.

[Hearing impairment in senile dementia of Alzheimer's type].
OBJECTIVE: To evaluate the pure tone hearing threshold and word recognition score of senile dementia of the Alzheimer's disease (AD) patients, and to analyze the relationship between hearing loss and the cognition impairment. METHODS: Pure tone audiometry, word recognition score (WRS), acoustic immittance and auditory brainstem response (ABR) are used to evaluate the auditory function of 43 patients with AD and 50 subjects of the control group. The confounding factors are controlled. RESULTS: The average age of 43 dementia patients was 72.7 +/- 6.4, and 69.7% was female. Bilateral hearing thresholds are similar in all subjects. All indices but Mini-mental scale of equastionnaire (MMSE) of patients and control group were not statistically different. There was no significant difference in pure tone audiometry (PTA), PTA2 (dB HL, mean +/- s) and WRS (%, mean +/- s) between the two groups (P > 0.05), therefore the hearing threshold of AD group (PTA = 26.3 +/- 8.5, PTA2 = 29.1 +/- 8.7, WRS = 85.5 +/- 15.5) is lower than that of control group (PTA = 23.2 +/- 10.6, PTA2 = 26.2 +/- 11.8, WRS = 87.6 +/- 16.8). No significant difference was found between the two groups in audiometry reliability, acoustic immittance and ABR (P < 0.05). CONCLUSION: No significant difference was found between the peripheral hearing dysfunction of AD patients and that normal elderly people, i.e., PTA, PTA2 and WRS were not related to MMSE.
