Abstract
A peritonsillar abscess is one of the most commonly occurring deep space infections of the head and neck in adults and children. A peritonsillar abscess that appears in newborns, however, is extremely rare. The treatment of a peritonsillar abscess requires both the selection of appropriate antibiotics and the best procedure to remove the abscessed material. We report a case of a peritonsillar abscess in a 40-day-old infant who was treated with antibiotic therapy alone.

Abstract
Aims The objective of the present study was to determine the specificity, sensitivity and accuracy of intraoral and transcutaneous ultrasound (US) in the diagnosis of peritonsillar cellulitis and abscess. Study Design Clinical-Prospective. Materials and Metods Thirty nine patients were seen at the otorhinolaryngology emergency department of the University Hospital, of the School of Medicine, University of São Paulo, with a clinical diagnosis of peritonsillar cellulitis or abscess. After initial evaluation, all patients were submitted to intraoral and transcutaneous US. Results Intraoral US was performed on 35 cases and its sensitivity was of 95.2%, the specificity was of 78.5% and the accuracy was of 86.9%. Transcutaneous US was feasible in all 39 patients and diagnosed peritonsillar abscess in 53.8%. There were 5 false-negatives and 1 false-positive result, sensitivity was 80%, specificity was 92.8% and accuracy was 84.5%. Conclusions Intraoral US was quite sensitive in the diagnosis of peritonsillar abscesses when performed by an experienced radiologist. Specificity was higher for transcutaneous US compared to intraoral US. However, when transcutaneous US was performed in patients with trismus, it was able to diagnose all peritonsillar abscesses, since they were large collections which are common in patients with trismus. These exams showed similar accuracy.

Abstract
PURPOSE OF REVIEW Peritonsillar abscess is a common problem, but some aspects of diagnosis and management remain controversial. We review the recent literature on peritonsillar abscess. RECENT FINDINGS Intraoral ultrasound can be a helpful diagnostic tool for peritonsillar abscess. For management, needle aspiration, incision and drainage, and quinsy tonsillectomy all yield successful results. Recent reviews have still not established that one treatment is consistently preferred. A randomized, placebo-controlled trail found that the use of intravenous steroids seems to reduce many symptoms, when used along with abscess drainage. SUMMARY The use of steroids may be beneficial in the treatment of peritonsillar abscess, and different techniques for abscess drainage are still used around the world, with consistently good results.

Abstract
BACKGROUND Infections of the deep neck spaces with accompanying mediastinitis are still a therapeutic problem with a high mortality. PATIENTS We report on three patients with deep neck space infections and accompanying mediastinitis who have been treated in the Departments of Otorhinolaryngology at the Universities of Bochum and Essen in the past 2 years. In two patients the infection originated from a peritonsillar abscess and in one patient from an odontogenic infection. THERAPY One patient was successfully treated by a tonsillectomy and drainage of the parapharyngeal abscess in conjunction with a thoracotomy because of a mediastinal abscess and bilateral pneumothorax. The second patient was cured by a tonsillectomy, wide cervical drainage und cervical mediastinotomy. The third patient with pre-existent alcohol abuse died because of multiorgan failure despite wide cervical und mediastinal drainage. CONCLUSION In every deep neck infection a mediastinal involvement has to be taken into account. Fast diagnosis and treatment are essential for the prognosis of this life-threatening disease.

Abstract
UNLABELLED Peritonsillar abscess (PTA) can be a life-threatening disease and may lead to significant complications without drainage. OBJECTIVES To describe the utility of ultrasound (US) in the evaluation of potential PTA and US-guided PTA drainage. METHODS The authors performed a retrospective US quality assurance review of all patients over 18 years of age scanned by emergency physicians for possible PTA. All patients presenting with PTA signs and symptoms including erythema and swelling of the tonsillar pillar and uvular deviation were eligible to be scanned. Patients confirmed to have an abscess on US had US-guided drainage followed by intravenous antibiotics in the emergency department and discharge home on oral antibiotics. Scans were performed by credentialed attending emergency physicians and residents. Researchers recorded patient symptoms, US findings, results of abscess drainage if performed, and any complications of drainage. All US examinations were performed with sheathed endocavity broadband US transducers on minimum depth and maximum resolution settings. Statistical analysis included descriptive statistics. RESULTS Forty-three patients received intraoral US examinations for suspected PTA. Thirty-five (81%) were diagnosed as having abscess on US. All abscesses were drained with an 18- or 14-gauge needle under US guidance. There were no drainage complications. There was one false positive with a focal area of edema yielding no pus on needle aspiration under direct US visualization. No patient returned unexpectedly after drainage. CONCLUSIONS These data suggest that intraoral US of suspected PTA allows for reliable diagnosis and safe and accurate abscess drainage.

Abstract
The diagnosis of peritonsillar abscess (PTA) poses a challenge to emergency physicians (EPs). The decision to perform an invasive procedure with potential complications is based on clinical judgment that is often inaccurate. Although there is some mention of intraoral ultrasound in otolaryngology practice, there is none in the emergency medicine (EM) literature. However, this bedside emergency application of ultrasonography has the potential to be of considerable use in EM practice, and could allow EPs who previously deferred blind needle aspiration of a potential abscess to perform the procedure themselves. We report the cases of 6 patients who presented with probable PTA and were evaluated with intraoral ultrasound at the bedside by an EP. All 6 patients then underwent needle aspiration. As diagnosed on ultrasound, 3 of the patients had negative aspirations and were diagnosed with peritonsillar cellulitis. Three others were found to have PTA, with 2 requiring real-time ultrasound needle guidance to accomplish abscess drainage after multiple failures with the blind approach.

Abstract
With the development of new antimicrobial agents, the incidence of peritonsillar abscess (PTA) is on the decline. PTA is still often encountered in general practice, however, where it requires immediate diagnosis and treatment. Because the internal carotid artery runs medially to the medial parapharyngeal space, damage to nearby vascular or other structures is a surgical risk of PTA. We used contrast computed tomography (CT) from PTA patients to investigate the anatomical relationship between the abscess and parapharyngeal space, and to determine safe surgical sites. We observed 31 patients with PTA--19 men and 12 women--between February 1997 and April 1999, all examined by contrast CT and undergoing drainage or incision. The average age was 30.7 years (range: 12-54 years). The abscess was on the right side in 20 cases and on the left side in 11. We determined the sites of the abscess and carotid artery, internal jugular vein, and surrounding soft tissue density area including nerves in the parapharyngeal space based on the angle and distance from recognizable anatomical structures in CT scans. The anterior margin of the parapharyngeal space was 29 +/- 5 mm posterior from the upper posterior alveolar margin. The medial margin of that space was at 15 +/- 2 degrees laterally from the midline of the incisors, and 24 +/- 4 mm laterally from the midline sagittal plane. The internal carotid artery was located medially to the parapharyngeal space, running on the sagittal plane containing the upper posterior alveolar margin. The distance from the anterior margin of the parapharyngeal space to the posterior wall of the PTA was 9 +/- 4 mm, and the distance to the anterior wall of the abscess (including the pharyngeal mucosa) was 31 +/- 5 cm. The relationship between the upper posterior alveolar margin and midline sagittal plane was useful for determining the site of the parapharyngeal space. Because the internal carotid artery is located on the same sagittal plane as the upper posterior alveolar margin, when conducting drainage or incision of PTA, we should advance sagittaLly from the point of incision to a depth of no more than 20 mm. If the tip of the instrument is kept medial to the sagittal plane of the upper posterior alveolar margin, effective treatment should be achievable without the risk of vascular damage.

Abstract
Peritonsillar Abscess (PTA) and Peritonsillar Cellulitis (PTC) are very similar clinical conditions. The differential diagnosis between them is made by needle aspiration, a very painful and invasive method. This study was performed at the Department of Otolaryngology at the Clinical Hospital of São Paulo University Medical School. It's aim was to evaluate the use of ultrasound as a noninvasive and inexpensive method of diagnosis, differentiating abscess from cellulitis. Twenty-one consecutive patients with a clinical diagnosis of peritonsillar infection were evaluated in the emergency service with a probable diagnosis of PTA. These patients were evaluated with intraoral and percutaneous ultrasound. Needle aspiration was used to compare and confirm the diagnosis. The sensitivity was 92.3% and specificity was 62.3%. The authors conclude that ultrasound is a good method to evaluate the differences between PTA and PTC.

Abstract
Peritonsillar abscess, a complication of tonsillitis, is not uncommon. The usual treatment consists of needle aspiration or surgical drainage and antibiotic treatment. Tonsillectomy may be used in the management of this condition, either at the time of diagnosis or after an interval period. Severe complications of peritonsillar abscess are rare. Synergistic necrotizing cellulitis is a fulminant infection associated with spread along fascial plains, necrosis of connective tissue and muscle, and high mortality. It is usually otondogenic in origin in the cervicofacial area and occurs in debilitated or immune compromised patients. We discuss cervicofacial-necrotizing soft tissue disease and report an unusual case of extensive synergistic necrotizing cellulitis of the neck, chest, and shoulder as a result of a peritonsillar abscess.

Abstract
Peritonsillar abscess is the most frequent complication of a tonsillar infection. The purulent material can spread from peritonsillar space to the fascial neck spaces. These deep neck infections may be a life threatening complication. The correct treatment of these infections is an appropriate antimicrobial therapy and abscess drainage, most of the times by surgery. We present a clinical case of a large perypharyngeal, and parotid abscess originated from a peritonsillar abscess. It was necessary surgical treatment to drain it.

Abstract
Peritonsillar infections include cellulitis and abscess (quinsy). Clinical diagnosis is often supplemented by diagnostic drainage (aspiration or incision) in an effort to distinguish abscess from cellulitis. In a prospective study of 14 patients we have shown that clinical impression alone is unreliable (sensitivity 78 per cent, specificity 50 per cent). Computerized tomography (CT) (sensitivity 100 per cent, specificity 75 per cent) and intraoral ultrasound (sensitivity 89 per cent, specificity 100 per cent) are much more reliable. We propose that intraoral ultrasound could play a useful role in the clinical assessment of peritonsillar infections helping to improve accuracy in distinguishing abscesses from cellulitis.

Abstract
The ultrasound appearances of peritonsillar abscesses (PTA) in 15 patients with clinically suspected peritonsillar infection were assessed using intra-oral sonography and computed tomography (CT). The ultrasonic appearances of an isoechoic rim with a hypoechoic centre were seen in the majority of cases, but a homogeneous isoechoic pattern was also recognized. The different ultrasonic appearances did not correlate with the number of symptomatic days. A central hypoechoic area with a surrounding isoechoic rim pattern was less likely if the volume of pus relative to the whole abscess was less than 10% on CT. Although the percentage of necrosis within the abscesses increased with time, the homogeneous isoechoic appearing abscesses, with less than 10% necrosis, did not fit in temporally and based on our findings it was not possible to predict the ultrasound appearances according to the duration of symptoms.

Abstract
A retrospective review was conducted of 91 patients with deep neck infections to determine the pattern of clinical disease and formulate a management plan. The spaces involved, as determined by clinical, radiologic, and operative findings, were the peritonsillar space (72 patients), parapharyngeal space (eight patients) submandibular space (seven patients), retropharyngeal space (one patient) superficial space (one patient), anterior visceral space (one patient), and visceral vascular space (one patient). Of the 19 patients who did not have a peritonsillar space infection the origin of the infection was found in eight; four of these were odontogenic. Thirty-eight patients required surgical drainage of the abscess. Five patients underwent tracheotomy due to increasing dyspnea. One patient with diabetes mellitus and a past history of myocardial infarction died of unknown cause. All other patients had an uneventful recovery without major complications. The combination of early radiologic diagnosis, effective antimicrobial therapy, and intensive surgical management contributed to the good prognosis.

Abstract
Peritonsillar abscess is an unusual complication following tonsillectomy. A series of five such patients is herein reported. Proper treatment begins with the initial tonsillectomy ensuring complete removal of the tonsils. Should a late peritonsillar abscess following tonsillectomy be found, the patient may be treated with needle aspiration of the affected area plus antibiotics. Removal of the remaining tonsillar tissue and surgical capsule of the tonsil is also advocated.

Abstract
Peritonsillar cellulitis and peritonsillar abscess are similar clinical entities with markedly different methods of treatment. Therefore, accurate diagnosis is paramount to appropriate treatment. This pilot study was designed to evaluate the sensitivity and specificity of intraoral ultrasound as a noninvasive method of differentiating abscess from cellulitis. Sixteen consecutive patients suspected of having peritonsillar abscess were prospectively evaluated with intraoral ultrasound. The results were confirmed with imaging or surgical drainage. Correct diagnoses were made in 9 (90%) of 10 abscesses and in 5 (83%) of 6 cases of cellulitis. Our results suggest that, while there is a learning curve for intraoral ultrasound, it is an accurate, noninvasive, and inexpensive tool to differentiate abscess from cellulitis. We believe that this will be a clinically useful technique in the future.

Abstract
The differentiation of a peritonsillar abscess from peritonsillar cellulitis, although difficult on physical examination, is required in order to determine the appropriate treatment. Peritonsillar cellulitis can be treated with antibiotics alone, while a peritonsillar abscess should be drained. Computed tomography (CT) of the neck is often performed to identify the formation of a deep abscess in the neck, but is rarely used to diagnose peritonsillar infections. We report a patient in whom CT was a useful diagnostic tool for distinguishing peritonsillar abscess from peritonsillar cellulitis.

Abstract
Descending necrotising mediastinitis is a rare but serious complication of oropharyngeal infections with high mortality. Diagnosis is frequently delayed, contributing to this high mortality, but awareness of such a complication and early diagnosis using computed tomographic scanning leads to prompt surgical drainage, proper antibiotic therapy, and survival.

Abstract
This study was conducted to determine the possibility of using an intracavitary ultrasound probe to differentiate between peritonsillar cellulitis and peritonsillar abscesses. Three volunteers and 11 of 12 patients were successfully scanned. The ultrasound method successfully demonstrated four cases of peritonsillar cellulitis and seven cases of peritonsillar abscesses. We conclude that ultrasound is a simple, safe, and noninvasive method of both assessing unilateral tonsillar swelling and determining the presence or absence of peritonsillar abscess.
