Hospital discharge survey on 4,199 peritonsillar abscesses in the Veneto region: what is the risk of recurrence and complications without tonsillectomy?

The Veneto region’s database of hospital discharge records was queried for ICD-9 codes corresponding to: peritonsillar abscess (PTA), PTA incision and drainage, tonsillectomy, pharyngeal-retropharyngeal abscess, cervical phlegmon, cervical abscess, and mediastinitis recorded from 1997 to 2006. All these codes were considered to identify cases of PTA recurrence and severe infectious complications occurring in conservatively treated patients. Among 4,199 patients whose PTA was incised and drained on admission to hospital, 1,532 were treated with tonsillectomy, while 2,667 were treated conservatively (without tonsillectomy). Abscess tonsillectomy was carried out almost exclusively in children (0–14 years of age), and only in 40 young and adult patients (0.95 %). The relapse rate after a single episode of PTA was 11.7 %, while potentially fatal complication occurred in 0.41 % of cases. Incidence of PTA hospital admission has remained stable in the considered period despite a 45 % reduction in the tonsillectomy rate. In conclusion, our data seem to show that conservative treatment for PTA is not associated with a significant risk of recurrence (and becomes minimal after 6–12 months), provided that patients have not suffered from previous PTA episodes.     

The usefulness of abscess tonsillectomy followed by intraoral drainage for parapharyngeal abscess concomitant with peritonsillar abscess in the elderly

Parapharyngeal abscess (PPA) may cause life-threatening complications and peritonsillar abscess (PTA) and tonsillitis frequently precede PPA. The optimal management of PPA caused by PTA has been the subject of debate with respect to the surgical approach. We present three cases of PPA concomitant with PTA in elderly patients. In two cases, the abscesses in parapharyngeal space were drained by abscess tonsillectomy followed by intraoral incision of the tonsillar bed. On the other hand, the third case did not undergo abscess tonsillectomy because of his refusal of surgery and needed extraoral drainage after the aggravation of PPA. Based on the experience of those three cases, it was suggested that abscess tonsillectomy followed by intraoral incision of the tonsillar bed might be a useful surgical approach for the drainage of PPA concomitant with PTA, especially in elderly patients.     

Peritonsillar abscesses in children

A follow-up retrospective study was performed on 41 children who presented with peritonsillar abscesses from 1970–1980. The ages ranged from 3 to 16 years, with the mean age of 10 years. There were 26 females and 15 males. The abscesses were predominantly left-sided (28 vs. 13 right-sided) and the mean duration of symptoms was 3 days. Of the patients, 39% had been treated with antibiotics prior to the abscess development. Only 15% of the patients had a documented past history of exudative tonsillitis. Of the 41, 1 patient was lost to follow-up, and 11 underwent tonsillectomy for the abscess. Thus, 29 patients were reviewed who received no surgical therapy for their peritonsillar abscess other than incision and drainage. These patients were contacted for an interval history with a period of follow-up ranging from 6 months to 10 years. Only 2 of the 29 patients (7%) had recurrent abscesses. Two other patients (7%) had further recurrent bouts of exudative tonsillitis but not abscesses. These 4 children were in an initial group of 6 who had a prior history of documented tonsillitis. The incidence of recurrent peritonsillar abscesses reported in the literature has ranged from 7.6 to 16% in series which were comprised mainly of adults. The low incidence of recurrent abscesses (7%) in this series would indicate a need to reevaluate the indication for tonsillectomy for peritonsillar abscess in the pediatric age group. The authors recommend that tonsillectomy be performed in those children who present with a pervious history of documented tonsillitis or suffer a complication at the time of the first abscess (neck abscess or airway compromise).     

Beidseitiger Paratonsillarabszess mit Lymphknotenabszedierung bei einem S?ugling

Peritonsillar abscess (PTA) comprises approximately 30% of soft tissue head and neck abscesses. Bilateral occurrence in infants is rare. The present case demonstrates a bilateral peritonsillar abscess with a lymph node abscess in a 10.5-month-old infant without the typical clinical findings of PTA. This report highlights the importance of including peritonsillar abscesses in the differential diagnosis of abscess-forming cases of lymphadenitis colli refractory to therapy, even if the classical symptoms are absent. In individual cases, the indication for image-guided procedures to establish the diagnosis of PTA should be made generously.     

Bilateral peritonsillar abscess with lymph node abscess in a infant. A rare case

Peritonsillar abscess (PTA) comprises approximately 30% of soft tissue head and neck abscesses. Bilateral occurrence in infants is rare. The present case demonstrates a bilateral peritonsillar abscess with a lymph node abscess in a 10.5-month-old infant without the typical clinical findings of PTA. This report highlights the importance of including peritonsillar abscesses in the differential diagnosis of abscess-forming cases of lymphadenitis colli refractory to therapy, even if the classical symptoms are absent. In individual cases, the indication for image-guided procedures to establish the diagnosis of PTA should be made generously.     

Peritonsillar abscess in children and its indication for tonsillectomy

38 children aged 1-15 years treated for peritonsillar abscess (PTA) between 1976 and 1986 have been reviewed. The patients were divided into those with a history of recurrent tonsillitis prior to developing PTA (T+) (10 patients = 26.3%) and those without such history (T-) (28 patients = 73.4%). 19 patients were surgically drained, 2 abscesses ruptured spontaneously, 2 patients were treated by repeated needle aspirations and 15 patients were treated by medication only. Neither the pre-PTA history (T+ versus T-) nor the mode of treatment during the acute event showed any significant differences in comparing the recurrency rate of PTA or tonsillitis. Therefore, it seems that a single event of PTA among pediatric population should not be considered an indication for tonsillectomy.     

Post-tonsillectomy haemorrhage: a retrospective comparison of abscess- and elective tonsillectomy

CONCLUSION: There is no increased risk of postoperative haemorrhage for abscess tonsillectomies in comparison to elective tonsillectomies. OBJECTIVE: There is still controversy as regards the optimal management of peritonsillar abscess. Opponents of tonsillectomy à chaud cite an increased postoperative bleeding risk. Most authors who compared the risks of postoperative haemorrhage after tonsillectomy à chaud and tonsillectomy à froid did not take into consideration criteria such as the age and gender of the patients or the experience of the surgeon. We aimed to eliminate this bias by performing a retrospective study in which a large series of abscess tonsillectomies were compared with an age- and gender-matched group of elective tonsillectomies. MATERIAL AND METHODS: All patients had been operated on at the Department of Otorhinolaryngology, University of Duisburg-Essen between March 1994 and August 2000. There were 350 patients in the abscess tonsillectomy group (61% male, 39% female; mean age 31.8 years; range 3-88 years) and 311 in the elective tonsillectomy comparison group (61% male, 39% female; mean age 30.0 years; range 2-83 years). RESULTS: In the abscess tonsillectomy group, 9 patients (2.6%; confidence level 1.1-4.8%) had postoperative haemorrhages which required treatment under general anaesthesia, compared to 17 (5.5%; confidence level 3.2-8.6%) in the age- and gender-matched group of "selected" elective tonsillectomies. The difference between these two rates was not significant (p = 0.056). The fairly high rate of haemorrhages in the elective tonsillectomy group was mainly due to the effect of the age-matching procedure, which excluded a considerable number of usually unproblematic tonsillectomies for tonsillar hyperplasia in young children. Moreover, our results show that there is a learning curve for surgeons performing tonsillectomies with regard to postoperative haemorrhages.     

Clinical advantage of abscess tonsillectomy in peritonsillar abscess

At the moment, regardless of the prevalence of the peritonsillar abscess (PTA), a definite protocol concerning the treatment of PTA has not yet been established and the treatment remains controversial. In the treatment of PTA the two most used therapeutic approaches are compared in this short study carried out on 16 patients. A group of patients presenting PTA received an abscess tonsillectomy (AT) is compared with another group treated with aspiration and subsequently operated on with interval tonsillectomy (IT). The results show obviously that the abscess tonsillectomy is better than the interval tonsillectomy in every aspect of treatment. The hospitalization time and global costs are also reduced. So when a young person has PTA and once the indication of tonsillectomy is posed, the operation has to be carried out "à chaud".     

Bilateral peritonsillar abscess: case report and literature review

Although uncommon, bilateral peritonsillar abscess (PTA) may still present with symptoms found in unilateral cases but lack hallmark findings such as an asymmetric tonsillar bulge and uvular deviation. We present the case of an 18-year-old woman deemed to have a bilateral PTA based on physical examination and radiographic imaging. She underwent successful surgical drainage with needle aspiration, followed by incision and drainage. A computed tomography with intravenous contrast should be obtained when a patient displays signs suggestive of a bilateral PTA but the diagnosis is not certain. To our knowledge, this is the first report of 2 different bacterial species cultured from contralateral abscesses during the same encounter.     

Who ends up having tonsillectomy after peritonsillar infection?

We wanted to explore how many patients will undergo tonsillectomy during the first 5 years after peritonsillar abscess or peritonsillar cellulitis, and why. In addition we sought predictive factors as to who would benefit from tonsillectomy. Medical records of 809 patients with peritonsillar infection (ICD-10 J36) aged over six were analyzed, and data on the history of tonsil infections and differences in treatment were collected. Data on patients who underwent tonsillectomy during the next 5 years were compared with data on patients needing no tonsillectomy. An abscess or planned interval tonsillectomy was performed on 159 patients. Of the conservatively treated 7- to 16.9-year-old patients, 42.5% required surgery later, of those aged 17–29.9 years, 31.3%, and those over 30, 13.2% (p < 0.001). Previous tonsillar infections led to increased (p = 0.067) probability of delayed tonsillectomy. Re-opening of the abscess cavity at the polyclinics, use of broad-spectrum antibiotics in the acute phase of infection, or being an outpatient or inpatient had no influence on the probability of later surgery. Overall one-fourth of the patients with peritonsillar infection underwent tonsillectomy during the next 5 years, even without being originally planned. Young age and previous tonsillar infections caused increased probability of delayed tonsillectomy.     

Peritonsillar abscess: recurrence rate and the indication for tonsillectomy

Two hundred ninety patients treated for peritonsillar abscess (PTA) between 1970 and 1982 were reviewed. The patients were divided into those with a history of recurrent tonsillitis prior to developing PTA (72 patients, 25%), and those without (218 patients, 75%). The patients in the first group had four times more recurrences than those in the second group (40% versus 9.6%). Patients older than 40 years were found to have a lower incidence of throat infections than younger patients, and no PTA recurrences were observed. Neither subsequent tonsillitis nor recurrent PTA was observed among 72 patients (25%) who underwent tonsillectomy 6 to 12 weeks after PTA. The pre-PTA history was found to be a dominant factor in determining the need for tonsillectomy. In patients who suffered from recurrent tonsillitis prior to PTA, tonsillectomy is recommended. In those with a single episode of PTA and no history of tonsillitis, tonsillectomy is not indicated.     

Changing Face of Treatment of Peritonsillar Abscess

Changing trends in the treatment of peritonsillar abscess are demonstrated by this retrospective study of 74 patients treated from 1975 through 1980 by a standardized regimen. This included needle aspiration at three points, intravenous antibiotics, hydration, and pharyngeal douches. The patients ' ages ranged from 11 to 73 years. There were 45 males and 29 females. Needle aspiration was positive in 52 patients (70%) and repeat aspiration was necessary in 10% of patients. Tonsillectomy was performed in 42 patients. No recurrent peritonsillar abscesses occurred during the 1 to 5 year follow-up of the 32 patients who did not have tonsillectomy. Recurrent tonsillitis did occur in 4 of these patients and 3 of them had a past history of recurrent tonsillitis. The authors conclude that treatment of peritonsillar abscess should consist of needle aspiration, intravenous antibiotics and supportive measures. Interval tonsillectomy should be performed only when there is a history of recurrent tonsillitis or previous peritonsillar abscess.     

Parapharyngeal abscess is frequently associated with concomitant peritonsillar abscess

To characterize patients with parapharyngeal abscess admitted to a Danish tertiary care centre and evaluate our management. This is a retrospective chart review. All records of patients with parapharyngeal abscess admitted to the Ear-Nose-Throat Department at Aarhus University Hospital, Denmark, from January 2001 through December 2011 were reviewed. In total, 63 patients (41 males), aged 4–89 years (median, 45 years) were included in the study. The mean annual incidence of parapharyngeal abscess was 0.9 cases/100,000 population. Thirty-three (52 %) patients had concomitant peritonsillar abscess. In two patients the parapharyngeal abscess was accompanied by necrotizing fasciitis. The most frequent surgical approach used was intrapharyngeal incision in combination with tonsillectomy. The most commonly used antibiotic regimen was benzylpenicillin plus metronidazole. Seven (13 %) patients returned to the operating theatre due to post-tonsillectomy haemorrhage or insufficient abscess drainage. Tonsillectomy and internal incision of the abscess in combination with a narrow-spectrum intravenous penicillin and metronidazole is a safe and efficient approach for managing parapharyngeal abscesses. This approach, however, carries a relatively high complication rate, requiring close surveillance in the early post-operative period. This is especially true for parapharyngeal abscess patients without peritonsillar abscess. In our series, these patients were more ill, more likely to experience complications, require intensive care, intubation, and tracheotomy, than parapharyngeal abscess patients with concurrent peritonsillar abscess. The frequent co-existence of parapharyngeal abscess and peritonsillar abscess favours careful consideration of addition of tonsillectomy to intrapharyngeal incision.     

Routine abscess tonsillectomy: late results.

The late results of abscess tonsillectomy as a routine treatment of peritonsillar abscess were investigated. The material comprises 113 patients. Follow-up was performed two to five years after the operation (bilateral dissection tonsillectomy under general anesthesia). Symptoms of pharyngitis, recurrent or chronic, were present in 17 percent of the patients, in most cases without major objective changes in the throat. The incidence of these symptoms was highest--70 percent--in patients past middle age without any history of trouble from the throat before the peritonsillar abscess. Tonsil remnants were seen in 28 percent, but only 6 percent of the patients had new episodes of febrile throat infections. The results are discussed. A reserved attitude to abscess tonsillectomy (and to interval tonsillectomy) is recommended for peritonsillar abscess in elderly patients without previous trouble from the throat.     

Peritonsillar abscess: Treatment with immediate tonsillectomy - 10 years of experience

Abstract Conclusion: Immediate tonsillectomy in patients with peritonsillar abscess is a safe and effective treatment that should be considered as an alternative to conventional incision and drainage. Objective: To assess the efficacy, safety, and microbiology of immediate tonsillectomy over 10 years, in patients with peritonsillar abscess. Methods: This was a retrospective study. We reviewed the clinical charts of patients diagnosed with peritonsillar abscess in Clínica Las Condes from September 2000 to August 2010, who were treated with immediate unilateral or bilateral tonsillectomy. The patients' epidemiological information, antibiotic therapy, laterality of the surgery, results of microbiological cultures, complications, and recurrences were recorded. Results: A total of 112 patients were studied, with a mean age of 24 years. There were no events of sepsis, and there were only four cases (3.6%) of postoperative bleeding, two of which resolved spontaneously. Only 29% of the patients required morphine pump-based analgesia in the postoperative period. The mean length of hospital stay was 3.4 days. Among the 28 unilateral tonsillectomies, 4 (14.2%) developed streptococcal tonsillitis and 2 (7.1%) were readmitted with a contralateral peritonsillitis: one cellulitis and one abscess that required drainage and tonsillectomy. The most frequently isolated microorganisms were gram-positive bacteria (Streptococcus pyogenes and other streptococci) and anaerobic bacteria (mainly Bacteroides spp. and Fusobacterium nucleatum).     

Peritonsillar abscess: risk of disease in the remaining tonsil after unilateral tonsillectomy à chaud

The occurrence of disease in the remaining tonsil after unilateral tonsillectomy à chaud in the treatment of peritonsillar abscess, was studied in 536 patients. No patient had a history of previous severe tonsillitis at the time of the unilateral tonsillectomy, 6.1 per cent of the patients were readmitted for surgery of the remaining tonsil during the follow-up period. Ninety-seven per cent of these patients were younger than 30 years of age. Previous investigations have shown increasing frequency by age of pharyngitis after bilateral tonsillectomy. We suggest bilateral tonsillectomy in all cases of patients younger than 30 years old who suffer from peritonsillar abscess irrespective of previous tonsillar disease. Patients older than 30 should be treated with unilateral ablation, unless there is a clear indication for bilateral tonsillectomy.     

Abscess tonsillectomy for acute peritonsillar abscess

Peritonsillar abscess (PTA) is a common but potentially serious complication of acute exudative tonsillitis. Several treatment guidelines have been described including needle aspiration, incision and drainage or abscess tonsillectomy. From January 1996 to September 2000 145 patients (53 female and 92 male, age range 3-95 years) were treated for PTA at the Department of Otorhinolaryngology, Head and Neck Surgery of the MLU Halle-Wittenberg, Germany. The highest incidence of PTA was observed in the second and third decades of life. Immediate abscess tonsillectomy was performed in 105 cases. This procedure, considered as safe and easy, has a lot of advantages. Compared with other treatments, it removes the abscess with amelioration of the trismus and dysphagia. Needle aspiration as the initial and only treatment was performed in 13 patients. In 20 patients without clinical improvement after aspiration, abscess tonsillectomy was undertaken. We conclude that immediately performed abscess tonsillectomy is an effective and safe treatment for peritonsillar abscess.     

Parapharyngeal abscess: diagnosis and treatment

To study the circumstances of diagnosis, predisposing factors, bacteriology and therapeutic management of parapharyngeal abscesses. This retrospective study over a period of 7 years concerned 16 patients hospitalized in an ENT and Head and Neck surgery department for parapharyngeal abscess. All patients were treated by intravenous antibiotics and steroids for 5–7 days. The length of hospital stay was 6–15 days. Parapharyngeal abscesses associated with peritonsillar and retropharyngeal abscess were all initially aspirated transorally for evacuation and bacteriologic examination. Five patients underwent surgical drainage (two via cervical incision, three by immediate tonsillectomy techniques and one by intra-oral drainage). Two patients presented jugular vein thrombosis. No life-threatening complication was observed. Patients were considered to be cured when cervical CT scan performed on D21-45 was normal. Parapharyngeal abscess is the second most common deep neck abscess after peritonsillar abscess. The diagnosis is both clinical and radiologic. CT scan is the best imaging examination for diagnosis and follow-up of parapharyngeal abscess. Non-complicated parapharyngeal abscesses require first-line medical management (intravenous antibiotics (amoxicillin and clavulanic acid) combined with steroids) and follow-up CT scan.     

Quinsy tonsillectomy.

The usual treatment for peritonsillar abscess in the United States is incision, drainage and antibiotic therapy followed by tonsillectomy several weeks later. Why this treatment began is not clear but it probably originated from fear of complications which might arise from operating during the acute stage. This therapy requires two hospitalizations and tonsillectomy after previous abscess can be difficult. Tonsillitis or peritonsillar abscess can recur any time after the initial abscess is treated. A series of 50 cases of peri-tonsillar abscesses treated by immediate tonsillectomy is presented and evaluated. The results show this operation has a low morbidity and no significantly greater complication rate than elective tonsellectomy.     

Smoking promotes the formation of peritonsillar abscesses

INTRODUCTION: Smoking has not properly been investigated as a predisposing factor for the development of a peritonsillar abscess. METHODS: In a retrospective study a group of 541 abscess tonsillectomies--performed in the department of Otorhinolaryngology (University of Duisburg/Essen) between 1994-2003--was retrospectively analysed for smoking habits of the patients. Further on we investigated the influence of smoking on the risk for a postoperative haemorrhage. RESULTS: Smoking habits of 519/541 were known, 296/519 (57%) were smokers, which is much more than expected with regard to the prevalence of smokers in the German population. Beneath the 2.2% of patients with a postoperative haemorrhage that had to be arrested under general anaesthesia no statistical relation between the occurrence of a postoperative haemorrhage and smoking was found. CONCLUSION: Smoking could be an important predisposing factor for the development of peritonsillar abscess e. g. due to alteration of the mucosa and microbiological changes. We could not identify a statistical relation between smoking and the risk of a postoperative haemorrhage after tonsillectomy à chaud.
