Acoustic characteristics of patients undergoing short-term endotracheal intubation with or without thyroidectomy who had no nerve injury / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: We carried out an acoustic analysis to investigate the phonatory characteristics of patients undergoing short-term endotracheal intubation with or without thyroidectomy, and who had no nerve injury. MATERIALS AND METHODS: The patients were divided into two groups, one undergoing thyroidectomy (39 cases) and the other not undergoing thyroidectomy (25 cases). All patients of the thyroidectomy group had undergone thyroidectomy using general anesthesia with endotracheal intubation. All patients of the other group had undergone chronic ear surgery with the same anesthetic method and duration. For the evaluation of voice, preoperative and postoperative acoustic analyses were done. RESULTS: On the acoustic analysis of thyroidectomy group, jitter, shimmer and the vocal range were significantly increased at one day after thyroidectomy. But one month after thyroidectomy, these changes return to statistically insignificant increments, except for shimmer and the vocal range. These acoustical changes were not related to the extent of surgery between total thyroidectomy and hemithyroidectomy. In comparison with acoustical changes after short-term endotracheal intubation, the change of jitter and shimmer of thyroidectomy group did differ significantly. CONCLUSION: Voice alteration after thyroidectomy without nerve injury may be associated with the disturbance of the prelaryngeal musculature. This voice changes emphasize the importance of the extralaryngeal skeleton for pitch control and early intensive speech therapy, especially in patients who need their voice professionally.

Clinical Characteristics of Chronic Paranasal Sinusitis in the Patients with End Stage Renal Disease

BACKGROUND AND OBJECTIVES: Infections account for much of the morbidity and nearly half of the mortality in renal transplant recipient. Recently there has been a marked increase in the number of renal transplantation and preoperative screening test for chronic paranasal sinusitis. Authors analyzed the clinical manifestations and postoperative courses after the endoscopic sinus surgery in the patients with end stage renal disease. MATERIALS AND METHODS: 1,175 patients had been consulted to the otolaryngology department for routine evaluations about the presence of acute and chronic paranasal sinusitis prior to kidney transplantation between Jun. 1989 to Aug. 1998. Among them, 30 patients were diagnosed as significant chronic paranasal sinusitis and 5 patients were treated with endoscopic sinus surgery. Medical records and radiographs of the 30 patients were reviewed retrospectively. RESULTS: The prevalence of chronic paranasal sinusitis in patients with end stage renal disease was 2.5%. Twelve patients were asymptomatic and chief complaints of symptomatic patients were nasal obstruction (55.6%), rhinorrhea (27.8%), and postnasal drip (16.7%). Eleven patients had nasal polyps and twelve patients showed purulent discharge. All the patients who were surgically treated experienced postopertive bleeding and 2 of them required transfusion. CONCLUSION: The presence of asymptomatic sinusitis among the patients with end stage renal disease necessitates diagnositc screening tests for chronic paranasal sinusitis. The incidence of postoperative bleeding after endoscopic sinus surgery in patients with end stage renal disease is much higher than that of otherwise healthy sinusitis patients.

Postoperative Results in Adult Patients after Tonsillectomy / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Although tonsillectomy is one of the most often performed surgeries in Otorhinolaryngology, there has not been any long-term postoperative follow-up studies until now. The authors aimed to validate once more, in a long-term follow up study, the need for performing tonsillectomy. MATERIALS AND METHODS: Medical records of 180 adult patients who have received tonsillectomy were retrospectively studied, and telephone surveys were made to the patients. The telephone questionnaire was designed to find out the postoperative pain, complications such as bleeding, the time each patient took to return to the normal diet and social life, the degree of improvement in the symptoms and the satisfactory rate. RESULTS: The chief complaints were recurrent sore throat. There was no immediate postoperative bleeding, but secondary bleeding occurred in 12.8% of the patients. The postoperative pain scored 7.4 in a scale of one to ten. The average time in returning to the normal diet and the normal life was 17.9, 21.1 days, respectively. Studies in the symptomatic improvement showed almost no or minimal residual symptom in 99% of the patients and about 95% of the patients answered positively in satisfactory category. CONCLUSION: Tonsillectomy caused great pain postoperatively in most of the patients and returning to the normal diet and life took fairly a long time. However, the positive answers about the symptomatic improvement and the high satisfaction rate validates tonsillectomy as an effective surgical treatment for patients with recurrent tonsillitis.
