Clinical Analyses of 115 Patients with Peritonsillar Abscess

Abstract

The clinical data of 115 patients with peritonsillar abscess (98 men and 17 women) treated between May 2011 and March 2014 were analyzed. We examined 9 items; the age, sex, affected side, duration of hospitalization, method of drainage, smoking history, history of diabetes, antibacterial drugs used, and the isolated bacteria. The disease predominantly affected males in their 30s (27.8% of all the patients). The median duration of hospitalization was 7 days. In regard to the affected side, the right side was affected in 52%, the left side in 44%, and both sides in 4%. The method of drainage used was incision in 63%, and puncture in 37%. In regard to the personal and past medical history, 51% of patients had a history of smoking and 3.5% had a history of diabetes. ABPC/SBT was used as the single-agent antibacterial drug in 75% of cases. The most commonly isolated aerobic bacteria were α-hemolytic streptococci, and the most commonly isolated anaerobic bacteria were Prevotella. The duration of hospitalization showed no significant correlation with the smoking history, drainage method or the antibiotic treatment used (ABPC/SBT single-agent or multiple drug use). On the other hand, the duration of hospitalization was significantly longer in the more than ≥65 years' age group than in the <65 years' age group. Therefore, especially careful interventions for prevention and treatment of peritonsillar abscess are required in the elderly. In relation to antibiotic selection, it may be reasonable to expect sufficient effect with the use of ABPC/SBT as a single agent, as this antibiotic has a broad antibacterial spectrum covering aerobic, anaerobic and drug-resistant bacteria.

Clinical Study of 107 Hospitalized Patients with Peritonsillar Abscess

“…3,6,14 Similar to previous studies, bacteria were detected in 36%, including mixed infections. Reports of CLDM-resistant bacterial strains have increased recently, 3,[14][15][16] and our investigation also detected 17% strains that were CLDM-resistant. None of the strains were resistant to ABPC/SBT, suggesting good therapeutic effects of ABPC/SBT monotherapy.…”

“…Anaerobic bacteria have been isolated in approximately 30 of 60% cases, depending on facilities. 3,6,14 Similar to previous studies, bacteria were detected in 36%, including mixed infections. Reports of CLDM-resistant bacterial strains have increased recently, 3,[14][15][16] and our investigation also detected 17% strains that were CLDM-resistant.…”

Clinical Study of 162 Cases of Peritonsillar Abscess Diagnosed by Contrast-Enhanced Computed Tomography

“…7,13 Regarding the affected side, many reports have indicated that there is no difference between the left and right sides and that bilateral cases account for approximately 1 to 5%. [2][3][4][5][6]10,11 In our patients, the rate of bilateral cases was somewhat high (6.2%), which could be attributed to the fact that all patients underwent contrast-enhanced CT and had lesions precisely evaluated in the present study. We believe that bilateral cases are more common than those reported to date.…”

“…Examination items included the following: (1) age and sex, (2) affected side, (3) number of patients according to type classification, (4) abscess diameter, (5) proportion of type per age, (6) bacteriological test results, (7) drug resistance, (8) treatment method according to type and diameter of abscess, (9) state of drug usage, (10) recurrence rate, and (11) recurrence time. However, when examining items 3, 4, 5, and 8, bilateral abscesses were treated as two separate cases or two sides.…”

Clinical Study of Postoperative Bleeding after Tonsillectomy in 497 Cases

“…1,4 In young individuals, peritonsillar abscess is common. [8][9][10] Scarring of areas surrounding the tonsils and vulnerable tissues causes difficulty in removing the tonsils and achieving hemostasis during surgery. Among the present cases, 15 were treated at our hospital for peritonsillar abscess (aged 20-56 years), of which 13 (86.7%) were aged 20 to 39 years.…”
