Outcomes of abscess tonsillectomy in patients awaiting tonsillectomy: A comparison with interval tonsillectomy.

PURPOSE: Peritonsillar abscesses (PTA) occasionally occur in patients who have a concurrent history of recurrent tonsillitis or prior PTA episodes. These patients sometimes meet the indications for elective tonsillectomy even prior to the current PTA event. Abscess ("Quinsy") tonsillectomy (QT) could serve as definitive treatment in this specific subgroup, though it is not performed often. The purpose of this study was to compare the perioperative outcomes between immediate QT and tonsillectomy performed several days (delayed QT) or weeks (Interval tonsillectomy, IT) after incision and drainage (I&D) of the PTA in this specific subgroup. MATERIALS AND METHODS: A retrospective perioperative outcomes analysis of patients undergoing tonsillectomy (2002-2022) compared QT to delayed QT and IT in patients with PTA meeting AAO-HNS elective tonsillectomy criteria. RESULTS: 110 patients were included: 55 underwent IT, 36 underwent delayed QT, and 19 underwent immediate QT. Postoperative hemorrhage rates were 14.5 %, 11.1 %, and 5.3 % for IT, delayed QT, and immediate QT, respectively (P = 0.08). Mean hospitalization durations were 7.98, 6.92, and 5.37 days for IT, delayed QT, and immediate QT, respectively (P < 0.01). IT had a higher readmission rate due to pain compared to QT (14.5 % vs. 1.9 %, p = 0.032). CONCLUSION: Immediate QT in PTA patients eligible for elective tonsillectomy is associated with lower postoperative hemorrhage, shorter admission time, and potentially reduced postoperative pain compared to I&D and delayed or interval tonsillectomy. These findings suggest that immediate QT should be considered as a primary treatment in this subgroup of eligible patients.

Peritonsillar abscess on NSQIP: Safety of indicated quinsy tonsillectomy.

OBJECTIVE: To compare surgical outcomes for children with peritonsillar abscess (PTA) who are taken to the operating room (OR) for incision and drainage (I&D) or quinsy tonsillectomy. METHODS: This is a multicenter retrospective study of pediatric patients who underwent I&D of a PTA between 2012 and 2017 included in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Patient demographics, comorbidities, and 30-day postoperative events (reoperation, readmission, and complications) were assessed. RESULTS: 777 patients were identified (mean age of 10.7 years, 54% female). 656 (84%) were admitted through the emergency department, and 395 (51%) met criteria for systemic inflammatory response syndrome or sepsis. Fifty-two (6.7%) had a quinsy tonsillectomy done at the time of incision and drainage. For quinsy tonsillectomy versus I&D alone, there was no statistically significant difference in length of stay (LOS) (1.9 v. 1.7 days, p = .523), readmission (17 v. 0, p = .265) or return to the OR (18 v. 1, p = .810). Patients younger than 5 years had a longer LOS (p < .001) while females (p = .003) and patients between 12 and 17 years of age (p = 0.021) were more likely to be readmitted. Of 725 patients treated with I&D alone, 10 (1.4%) patients required a repeat I&D and 6 (0.83%) went on to have an interval quinsy tonsillectomy. CONCLUSIONS: Outcomes of I&D and quinsy tonsillectomy for pediatric PTA in the operating room are the same. If tonsillectomy is indicated in the case of recurrent tonsillitis or PTA, a quinsy tonsillectomy is a good option.

[Comparison of pain after laser and traditional extracapsular tonsillectomy]. / Sravnenie vyrazhennosti bolevykh oshchushchenii posle lazernoi i traditsionnoi ekstrakapsulyarnoi tonzillektomii.

OBJECTIVE: To compare the pain during the postoperative period after the extracapsular tonsillectomy, performed with the 1.94 µm laser and cold steel tonsillectomy. MATERIAL AND METHODS: Sixty patients with chronic decompensated tonsillitis were enrolled in the study. Patients were randomized into two groups: the first one was subjected to cold steel tonsillectomy; in the second group tonsillectomy was done using a laser with 1.94 µm wavelength at pulsed mode. Patients' anamnesis was evaluated (the presence of signs of a toxic-allergic form of the disease, peritonsillar abscesses, the duration of the disease and the frequency of exacerbations of tonsillitis per year). In the postoperative period patients filled out questionnaires: the severity of pain was assessed for 10 days in points from 0 to 10, and painkiller use frequency per day. RESULTS: Statistical analysis revealed that the pain after tonsillectomy depends on the presence of peritonsillar abscesses in the anamnesis. In patients with abscesses, the pain and the need for anesthesia are significantly lower with the laser technique compared with cold steel. The tonsillectomy technique does not affect the risk of postoperative bleeding (in both groups - 1/30). CONCLUSION: The postoperative period after extracapsular laser tonsillectomy is characterized by significantly less pain than traditional tonsillectomy with cold instruments in patients with a history of peritonsillar abscess. Laser tonsillectomy does not have an increased risk of bleeding compared to traditional tonsillectomy.

Bilateral Intratonsillar Abscesses: A Deceiving Symmetrical Oral Bulging.

BACKGROUND: Unilateral intratonsillar abscess (ITA) is an underreported, well-known complication of acute tonsillitis. The prevalence of unilateral ITA compared to peritonsillar abscess (PTA) is 1:14. However, bilateral ITA is an extremely rare entity, with only four cases reported thus far. OBJECTIVES: To describe past cases and our experience, elaborating the diagnostic challenge and the surgical treatment for bilateral ITA. METHODS: We conducted a literature search in the PubMed database using the key words intra-tonsillar abscess, tonsillar abscess, bilateral tonsillar abscess, bilateral intra-tonsillar abscess and bilateral peritonsillar abscess. Our search was limited to the years 1980 to 2020. RESULTS: We found that only four cases of bilateral ITA were previously published. All were characterized by a delay in diagnosis with a median of 10 days (4-14 days), symmetrical oral cavity appearance, enlarged bilateral kissing tonsils, and subsequent treatment by surgical drainage/paracentesis. Respiratory compromise was a concern in most cases. Our patient was treated with bilateral quinsy tonsillectomy and had a prompt recovery. CONCLUSIONS: Bilateral ITA is a rare, deceiving entity, with a diagnosis delay attributed to the symmetrical oral bulging. We present the fifth case reported and the first ever reported in a pediatric patient. We describe the assumed pathogenesis and the main characteristics among all five patients, emphasizing the important role of a high index of suspicion and appropriate imaging, guiding to proper diagnosis and treatment.

Tonsillectomy as a risk factor of periodontitis: A population-based cohort study.

BACKGROUND: To determine whether patients who had undergone tonsillectomy would have higher risks of postoperative periodontitis. METHODS: Data were collected from the Taiwan Longitudinal Health Insurance Dataset from 1999 to 2013, a population-based cohort study consisting of cases of newly-onset sleep apnoea, chronic diseases of tonsils and adenoids, peritonsillar abscess, and periodontal diseases. A total of 1482 tonsillectomy cases and 14,796 non-tonsillectomy controls were selected. Propensity score matching37 between the tonsillectomy group and the non-tonsillectomy group was conducted to exclude the confounding effect resulting from indications of tonsillectomy. Cox proportional hazard model and subgroup analyses were conducted to identify subpopulations at risk of tonsillectomy-associated periodontitis, and a sub-outcome analysis was applied to identify the subtype of tonsillectomy-associated periodontitis. RESULTS: A total of 648 patients who had undergone tonsillectomy and 648 out of 6509 propensity score-matched controls were retrieved, among which 230 cases in the tonsillectomy group were associated with post-surgical periodontitis (adjusted HR = 1.31, 95% CI = 1.08 to 1.59). The association persisted in a subpopulation of patients with periodontitis who received mechanical and surgical treatments for periodontitis (adjusted HR = 1.33, 95% CI = 1.09 to 1.63). The incidence of periodontitis was significantly high in the individuals who underwent tonsillectomy and was particularly high in those that were below 12 years of age (HR = 1.58, 95% CI = 1.10 to 2.27). The risk of periodontitis increased 4 years after tonsillectomy (HR = 1.82; 95% CI = 1.29 to 2.59). The majority of post-tonsillectomy periodontitis was aggressive and acute periodontitis (HR = 1.37; 95% CI = 1.10 to 1.71). CONCLUSIONS: Tonsillectomy performed in pediatric patients of < 12 years old, increased the risk of developing periodontitis. Aggressive and acute periodontitis as a long-term, postoperative adverse event took place at 4 years or longer after tonsillectomy.

Feather foreign body caused periparotid and peritonsillar abscess in a 9-month-old girl.

Migratory foreign body appeared to be bird feather, caused peritonsillar and periparotid abscess in a nine-month-old infant. Patient presented painful, tender and fluctuating red neck mass on the left neck region II, and refusal of oral intake, with no fever. Azithromycin was introduced four days before presentation for suspected urinary tract infection. ENT examination revealed left peritonsillar abscess; ultrasound confirmed periparotid abscess, MSCT verified both diagnoses. Under general anaesthesia, we performed abscess incision, after pus drainage, small foreign body spontaneously came through the wound. After washing it with saline, it appeared like a bird feather. Subsequently, peritonsillar abscess was incised and drained. After 24-hour postoperative care on pediatric intensive care unit, the patient continued three-day parenteral antibiotic treatment on the otolaryngology department; it was discharged with a recommendation to continue seven days of oral antibiotic therapy. Suggested mechanism was ingestion of bird feather from stuffed bedding, that got trapped in the tonsillar crypt. Afterwards, it started to migrate through the neck tissue. Households with children younger than three years should not have feather stuffed clothes or beddings.

A pilot study on pediatric mononucleosis presenting with abscess.

CONTEXT: To describe this new clinical entity, diagnosis, and potential management of pediatric intratonsillar/peritonsillar abscesses in children affected by infectious mononucleosis. METHODS: After institutional review board approval, a retrospective chart review of patients who underwent testing for infectious mononucleosis and also had a computed tomography scan of the head and neck was completed. Those who did not have imaging showing the palatine tonsils and those with insufficient testing to diagnose infectious mononucleosis were excluded. MAIN FINDINGS: One hundred patients were included in the study; 15 had a peritonsillar abscess and 29 had an intratonsillar abscess. Four of the patients with a peritonsillar abscess (26.7%) had a positive Monospot or Epstein-Barr virus IgM result, and two of 15 (13.3%) had positive rapid strep or culture results. Of the 29 patients with an intratonsillar abscess, eight (27.6%) had a positive Monospot or Epstein-Barr virus IgM result while two (6.9%) had a positive rapid strep or culture result. Of those with bilateral intratonsillar abscess, five of 12 (41.7%) patients showed laboratory markers for infectious mononucleosis compared with three of 17 (17.6%) with unilateral intratonsillar abscess. This difference was not statistically significant (Fischer's, p = 0.218). CONCLUSION: In our cohort of patients undergoing computed tomography scan and acute infectious mononucleosis testing, patients with intratonsillar and peritonsillar abscess tested positive for mononucleosis markers more commonly than for streptococcus markers. Recognizing uncomplicated intratonsillar and peritonsillar abscess in the setting of infectious mononucleosis in these pediatric patients may help tailor management in this population.

Smoking and Alcohol Consumption Are Associated With the Increased Risk of Peritonsillar Abscess.

OBJECTIVES/HYPOTHESIS: The purpose of this study was to evaluate the relationship among smoking, alcohol consumption, and peritonsillar abscess in a Korean population. STUDY DESIGN: Individuals ≥40 years old from the Korean National Health Insurance Service-Health Screening Cohort were assessed from 2002 to 2013. METHODS: In total, 1,285 peritonsillar abscess participants were matched with 5,140 controls at a ratio of 1:4 with respect to age group, sex, income group, region of residence, hypertension, diabetes, and dyslipidemia. We analyzed the participants' previous histories of smoking (current smokers vs. nonsmokers or past smokers) and alcohol consumption (drinkers vs. nondrinkers) in the peritonsillar abscess and control groups. Peritonsillar abscess was defined using the International Classification of Disease-10 code J36 combined with claim codes for incision and drainage or aspiration. Crude and adjusted odds ratios (ORs) were analyzed using unconditional logistic regression analyses, and 95% confidence intervals (CI) were calculated. RESULTS: The rates of smoking and consuming alcohol were higher in the peritonsillar abscess group than in the control group. The adjusted OR of smoking for peritonsillar abscess was 1.23 (95% CI = 1.06-1.44, P = .009), and that of alcohol consumption was 1.18 (95% CI = 1.02-1.36, P = .024). CONCLUSION: The odds of smoking and alcohol consumption were increased in peritonsillar abscess patients compared to those in the control group. LEVEL OF EVIDENCE: NA Laryngoscope, 2020.

Peritonsillar abscess in an infant with congenital bone marrow failure.

Peritonsillar abscess is extremely rare in infants and is potentially life-threatening. We report the case of a 3 month old infant with a background of congenital bone marrow failure who presented with sepsis and desaturation requiring intubation and PICU care. Ultrasound and CT scan revealed an inflammatory mass. Examination in theatre revealed a self-draining quinsy. Following formal drainage in theatre, the child improved and was extubated uneventfully 1 day later. Prompt surgical and medical management as well as the presence of a well-coordinated multidisciplinary team are crucial in ensuring the adequate management of complex paediatric patients.

Ten years of deep neck space abscesses.

BACKGROUND: The incidence of deep neck space abscesses, which can result in significant morbidity and mortality, is rising. The aetiology is thought to be dental. However, this study suggests a reduction in tonsillectomies may be associated with the rise. METHOD: In a retrospective cohort study, patients were identified by a clinical code within one hospital over 10 years. Evidence of preceding infection source, management, lifestyle risks, comorbidities and demographics were extracted. RESULTS: Fifty-two patients were included: 23 (44 per cent) had concurrent or recent tonsillitis; 11 (21 per cent) had poor dental hygiene; 22 (42 per cent) were smokers; and 9 (17 per cent) had diabetes. The incidence of deep neck space abscess cases increased from 1 in 2006, to 15 in 2015 (correlation value 0.9; p = 0.00019). CONCLUSION: The incidence of deep neck space abscess cases is increasing. Risk factors include tonsillitis, smoking and dental infection. This paper adds to the growing evidence that deep neck space abscesses are increasingly related to tonsillitis, and questions whether the threshold for tonsillectomy has been raised too high.

The Liverpool Peritonsillar abscess Score: Development of a predictive score through a prospective multicentre observational study.

OBJECTIVES: While uncommon in the population at large, peritonsillar abscess (PTA) is a common subject of ENT referrals. Missed or uncertain diagnosis is a source of concern for non-specialist referrers. In line with the NHS England Second Sepsis Action Plan, we aimed to develop a predictive score for the presence of PTA. This would help to improve non-specialist colleagues' diagnostic certainty as well as to support ENT surgeons' triage of these referrals. DESIGN: Prospective, multicentre observational study. SETTING: Primary and secondary care. PARTICIPANTS: Patients >16 years with symptoms of sore throat. DATA: We prospectively collected comprehensive data on patient demographics, symptoms and clinical status. We documented whether the patient had aspiration-proven PTA or not. We performed binary logistic regression analysis, iterative development of a predictive score which we validated internally. RESULTS: 100 patients were included (46 PTA and 54 tonsillitis). Five variables added significantly to the logistic regression model: unilateral sore throat; trismus; male gender; pharyngeal voice change; and uvular deviation. Using the odds ratio outputs, we developed the Liverpool Peritonsillar abscess Score (LPS) iteratively. We validated the latest (third) iteration of the LPS internally (ie, on the same sample), yielding sensitivity 96%; specificity 85%; positive predictive value 85%; and negative predictive value 96%. The area under the receiver operating characteristics (AUROC) curve was 0.970. CONCLUSIONS: We have developed the first predictive score for PTA based on symptoms and signs that do not require the user to have specialist experience. Its high negative predictive value may be particularly helpful to non-specialist colleagues.

Non-steroids anti-inflammatory drugs and risk of peritonsillar abscess in pharyngitis: a French longitudinal study in primary care†.

BACKGROUND: The safety of non-steroids anti-inflammatory drugs (NSAIDs) in the context of pharyngitis is doubtful with contradictory results in the literature. OBJECTIVE: To evaluate the risk of peritonsillar abscess (PTA) associated to NSAIDs consumption during a pharyngitis episode observed in primary care. METHOD: A retrospective cohort study using Observatory of General Medicine Datalink from 1995 to 2010. All patients consulting a GP from the Datalink network for pharyngitis have been included. The occurrence of a PTA in the 15 days following the consultation for pharyngitis was matched. The association between PTA and prescriptions of NSAIDs was studied via an adjusted logistic regression model. RESULTS: During the study period, 105 802 cases of pharyngitis and 48 cases of PTA following a pharyngitis were reported, concerning respectively 67 765 and 47 patients. In the multivariate analysis, the risk of PTA was associated positively with a NSAIDs prescription (OR = 2.9, 95% CI = 1.6-5.2). Other factors associated with PTA occurrence were the prescription of corticosteroids (OR = 3.1, 95% CI = 1.3-7.6) and an age between 20 and 40 years (OR = 5.7, 95% CI = 2.5-13.0). The prescription of antibiotics was not significantly associated with PTA (P = 0.7). CONCLUSION: Prescription of NSAIDs in pharyngitis may increase the risk of PTA. This study encourages considering cautiously the balance between benefits and harms before prescription of NSAIDs for pharyngitis.

Analysis of smoking behaviour in patients with peritonsillar abscess: a prospective, matched case-control study.

OBJECTIVE: Smoking is purported to increase the risk of peritonsillar abscess formation, but prospective data are needed to confirm this hypothesis. This prospective study aimed to identify this correlation. METHODS: Fifty-four patients with peritonsillar abscess were prospectively asked about their smoking behaviour using a questionnaire that was designed and approved by the Robert Koch Institute (Berlin, Germany) to analyse smoking behaviour in epidemiological studies. Afterwards, a consecutive control group (without peritonsillar abscess), matched in terms of age and gender, was surveyed using the same questionnaire. A classification of smoker, former smoker and non-smoker was made, and the numbers of pack-years were calculated and compared. RESULTS: Statistical analysis of both groups revealed a significant correlation between peritonsillar abscess and smoking experience (p = 0.025). Moreover, there were significantly fewer non-smokers in the non-peritonsillar abscess group (p = 0.04). The number of pack-years was higher in the peritonsillar abscess group (p = 0.037). CONCLUSION: There is a statistically significant association between peritonsillar abscess and smoking.

Diagnostic role of mean platelet volume in tonsillitis with and without peritonsillar abscess.

OBJECTIVE: To assess the diagnostic role of mean platelet volume in tonsillitis with and without peritonsillar abscess. METHODS: Mean platelet volume and other laboratory data were retrospectively investigated. RESULTS: Mean platelet volume was significantly lower in the tonsillitis group (7.8 per cent ± 0.7 per cent) than in the control group (8.7 per cent ± 0.6 per cent; p < 0.0001), and it was significantly lower in the abscess group (7.5 per cent ± 0.6 per cent) than in the no abscess group (8.0 per cent ± 0.7 per cent; p = 0.0277). White blood cell counts and C-reactive protein levels were not significantly different between patients with an abscess and those without. The mean platelet volume cut-off values for the diagnosis of tonsillitis and peritonsillar abscess were 7.95 fl and 7.75 fl, respectively. CONCLUSION: Our results suggest that a decreased mean platelet volume is associated with the development and severity of tonsillitis. This finding provides useful diagnostic information for physicians treating patients with tonsillitis.

Unusual 'feathery' cause of a parapharyngeal abscess in an infant.

A 7-month-old boy presented to the emergency department with reduced oral intake, neck swelling and fever. Clinical examination revealed a 3 cm left parotid and left level I neck swelling with left medialised tonsil but no trismus. Computed imaging confirmed the presence of an abscess in the peritonsillar area with extension into the parapharyngeal space and deep lobe of the parotid gland. The abscess was incised and drained transorally. Following drainage of the abscess, a small 3 mm suspicious foreign body was seen. After extraction, this was revealed to be a 60 mm feather. We would like to highlight this unusual case in an infant and to ensure that foreign body is considered as aetiology. There are only a handful of cases in the literature involving feathers causing neck abscesses and, to our knowledge, this is the first case where the patient presented with a pharyngeal abscess, which was drained transorally.

[The specific features of the past medical history and etiology of pharyngeal abscess in the children]. / Osobennosti anamneza i étiologii abstsessov glotki u detei.

The present study was undertaken for the purpose of elucidating the specific features of the past medical history and the etiological factors responsible for the development of tonsillogenic pharyngeal abscesses in the children. We performed the retrospective analysis of the medical histories of 291 children presenting with this condition who had been admitted for the treatment to the ENT Department of the Morozovskzya City Children's Clinical Hospital during the period from January till December 2015. The study has demonstrated the following most common shortcomings of the outpatient treatment of the patients suffering from chronic tonsillitis at the stage preceding formation of paratonsillar abscess: inadequate antibacterial therapy of acute chronic tonsillitis or its exacerbation and limited indications for tonsillectomy at the level of the outpatient treatment. The leading role in the etiology of tonsillogenic pharyngeal abscesses in the children is played by beta-hemolytic Streptococcus of group A. It is concluded that the medical history suggesting past paratonsillar abscess is the absolute indication for the subsequent tonsillectomy in the children of any age.

The presence of minor salivary glands in the peritonsillar space.

Peritonsillar abscess (PTA) is traditionally considered only a purulent complication of acute tonsillitis (AT), but may be related to infection of minor salivary glands. We analysed the presence of peritonsillar minor salivary glands and inflammation patterns in 114 adult tonsils representing three patient groups: recurrent AT, chronic tonsillitis (CT), and PTA. Samples acquired from elective tonsillectomies were stored in formalin, and after preparation were microscopically examined for inflammation and fibrotic changes. Clinical features and histological characteristics were compared between the groups. Of all tonsils, the minor salivary glands were present in 77 (67.5%). Glands located near the tonsillar tissue showed signs of infection in 73 (94.8%), while only 3 (15.0%) of 20 glands located deeper in the peritonsillar space were infected. Compared to patients with recurrent AT and CT, those with PTA more often presented with periductal inflammation, p < 0.011 (PTA 82.1%, AT 42.9%, and CT 63.6%). The majority of our 114 tonsillectomy specimens, collected from patients with AT, CT, or PTA, presented with infected minor salivary glands, and inflammation of the peritonsillar space glands was evident. To further elucidate the association between these glands and PTA, tonsillar samples should be collected and analysed from patients during the acute phase of infection.

Peritonsillar abscess: epidemiology and relationship with climate variations.

BACKGROUND: Peritonsillar abscess is the most common deep infection of the head and neck in young adults. It is considered a purulent complication of acute tonsillitis, but other mechanisms have been proposed. There is no consensus as to whether seasonality affects peritonsillar abscess incidence. METHODS: This observational, descriptive, retrospective study explored the epidemiology of peritonsillar abscess and its relationship with seasonality. The cases were selected from the emergency otolaryngology service of a tertiary hospital. RESULTS: The sample comprised 528 patients (42.61 per cent males, mean age = 26.63 years). A moderate positive correlation was found between peritonsillar abscess incidence and monthly average temperature. No associations were found with insolation, precipitation or humidity. CONCLUSION: In this sample, peritonsillar abscess was more likely to occur in warmer months. The findings corroborate the theory that peritonsillar abscess is not a direct complication of acute tonsillitis and may improve understanding of peritonsillar abscess aetiology.
