Article Synopsis
- The deaths of 5 children from posttonsillectomy haemorrhage in Austria spurred a national conversation and the creation of new guidelines for tonsil surgery focused on patient safety.
- A study was conducted involving 6,765 patients under 18 years old to assess the incidence of postoperative bleeding after tonsil surgeries, revealing a 15% complication rate for tonsillectomy versus 2.3% for tonsillotomy, with risks increasing with age.
- The findings indicated a shift towards more tonsillotomies in children under 6 since 2007, along with recommendations for overnight hospital observation for patients experiencing any bleeding after surgery.
Significant post-tonsillectomy pain is associated with increased risk of hemorrhage.

Article Synopsis
- The study aimed to explore the link between different types of postoperative pain and the risk of bleeding after tonsillectomy in 335 patients.
- Researchers identified five distinct pain types, with types I and II showing decreasing pain levels, while types III, IV, and V exhibited increasing pain and higher bleeding risks.
- The findings indicate that patients experiencing severe or escalating pain shortly after surgery are at a greater risk of hemorrhage.
Article Synopsis
- The study investigates the relationship between coagulopathy (a bleeding disorder) and postoperative hemorrhage risk in adults undergoing tonsillectomy, with specific hypotheses about the risks associated with personal history and laboratory screenings for coagulopathy.
- Analyzing data from 3,041 tonsillectomy patients over nine months, the study found that a positive history of coagulopathy significantly increased the risk of postoperative hemorrhage, while laboratory screening did not show a significant correlation.
- The conclusion emphasizes the importance of evaluating a patient's history of coagulopathy before surgery, as it doubles the risk of postoperative hemorrhage compared to those without such a history.
Background: There is extensive evidence that electrosurgical current application increases hemorrhage when compared with "cold" dissection and hemostasis. The way that the "hot" technique is used may influence the outcome decisively.
Methods: Temperature-time functions were measured in distances of 3 to 12 mm underneath the surface at which bipolar electrosurgical current was applied.
Article Synopsis
- Intraconal tumors of the orbit are rare and challenging to treat surgically, but endoscopic transnasal techniques offer a new approach, with limited prior studies available.
- The Graz study introduced a method for temporarily medializing the medial rectus muscle during endoscopic surgeries, analyzing patient data from 2006 to 2010 involving six patients with various intraorbital tumors.
- Results showed successful outcomes for four patients with hemangiomas and a Schwannoma, allowing for safe biopsy and resection, highlighting good visibility and minimizing scars as advantages of the endoscopic method, while noting some limitations for certain tumor locations.
Article Synopsis
- The study introduces a new classification system for categorizing the severity of postoperative hemorrhage following tonsillectomy, tonsillotomy, and adenoidectomy, and aims to identify risk factors contributing to the frequency and severity of these bleeding episodes.
- Conducted as a multicenter cohort study in Austria from October 2009 to June 2010, it analyzed data from 9,405 patients and recorded various surgical details alongside instances of postoperative bleeding.
- The findings revealed that minor bleeding episodes significantly increase the likelihood of severe bleeding, with higher rates observed in adults, those undergoing tonsillectomy, and specific surgical techniques, among other risk factors.
Article Synopsis
- Inverted papillomas (IP) are usually benign tumors found in the sinuses, with up to 4% prevalence, but they can sometimes grow aggressively and become malignant.
- A case study is presented involving a 69-year-old woman whose IP rapidly invaded surrounding structures, including the orbit and skull base, and transformed into an invasive carcinoma within 3 months.
- Despite the initial benign histology of the papilloma, close endoscopic monitoring is essential for detecting possible malignant transformation, as conventional surgical methods may fail due to fast recurrence.
Objectives: To evaluate whether patients with abnormal Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) benefit from proton pump inhibitor (PPI) therapy.
Study Design: Open, multicenter, prospective longitudinal cohort study.
Methods: Patients with suspected reflux-associated laryngologic symptoms were evaluated by 40 community practice otolaryngologists using RSI and RFS.
Tonsilar haemorrhage and re-admission: a questionnaire based study.
Eur Arch Otorhinolaryngol
December 2011
Article Synopsis
- The study aimed to assess the actual rate of postoperative bleeding (haemorrhage) in community patients undergoing tonsil surgeries compared to hospital recorded rates.
- Data was collected from 695 patients, with 407 responding to a questionnaire, revealing that 24.6% experienced some form of bleeding, but only 19.4% of those cases were documented by hospitals.
- The overall estimated haemorrhage rate was 21.4%, indicating that relying solely on hospital records would underestimate the true incidence of bleeding after tonsil operations.
Article Synopsis
- The study aimed to examine whether eosinophil major basic protein is present in high levels in the nasal mucus of patients with polypoid chronic rhinosinusitis.
- It involved comparing 23 patients with the condition to 21 individuals from three control groups who didn't have chronic rhinosinusitis.
- The results showed that 87% of patients with polypoid chronic rhinosinusitis tested positive for eosinophil major basic protein, whereas only one control did, suggesting it could be a valuable diagnostic marker for the condition.
Unlabelled: Acoustic rhinometry is an objective method to determine nasal cavity geometry. The technique is based on sound wave reflexion analysis in the nasal cavity, and determines crossectional areas as a function of distance as well as volume.
Aim: The purpose of this study is to analyse nasal cavity volume changes caused by functional endoscopic sinus surgery (FESS) in adults with chronic rhinosinusitis by acoustic rhinometry, and to correlate these changes with improvements in the sensation of nasal obstruction.
Pharyngoesophageal gastric acid reflux is thought to initiate chronic posterior laryngitis. The gold standard for measuring gastric reflux is dual-channel 24-hour pH monitoring. This is a time-consuming, inconvenient, expensive method that is not available in all areas.

For evaluation the patients were asked about their subjective impression of voice changes using a questionnaire. An objective assessment was performed by determining the so-called nasalance using the Nasometer (Kay Elemetrics), preoperatively, on the immediate postoperative follow-up (2 days after surgery), and approximately 1 month after surgery.

Dysregulation of connexin expression is believed to have a role in carcinogenesis. The human prostate has been reported to express connexin 32 and 43.
