The Impact of Tobacco Smoking Upon Chronic/Recurrent Tonsillitis and Post Tonsillectomy Bleeding

Prevalence of electronic smoking exposure and tonsillectomy surgery in children

OBJECTIVE

The hypothesis tested was the negative impact of electronic smoke exposure on the developing of respiratory infection, specifically in the upper tract. In this study, we aimed to investigate if smoke exposure increased the number of tonsillectomy surgery in children compared to the hernia repair control group.

METHODS

The design of our study was retrospective case-control. We retrospectively reviewed medical records or children of up to 12 years of age that were admitted for tonsillectomy at King Abdullah University Hospital (KAUH) from January 2019 to December 2023 to determine exposure to both electronic and tobacco smoking. Records of hernia repair surgery children aged 12 and less at this facility were also retrospectively reviewed for both electronic and tobacco smoke exposure during the same period. Data was collected from medical records and phone call interviews with the patients and their families.

RESULTS

A total of 743 children were included, 64 % were males. The participants were divided into two groups: 439 had recurrent tonsillitis and needed tonsillectomy, the other 304 underwent hernia repair surgery (control group). Overall, 28 % of children were exposed to electronic smoking, 29 % to tobacco smoking, and 5.9 % to both. Electronic and tobacco smoke exposure was significantly evident among the tonsillectomy group compared to the hernia group. Logistic regression analysis showed that exposure to electronic smoking (OR: 2.74) and tobacco smoking (OR: 2.47) were significantly associated with an increased likelihood of undergoing tonsillectomy. However, patients with exposure to both smoking types did not show a significant link, while the absence of any smoking exposure was significantly associated to lower odds of tonsillectomy.

CONCLUSION

Children who underwent tonsillectomy had a higher likelihood of being exposed to tobacco or electronic smoking compared to children in the hernia repair surgery group.

Evaluation and Risk Factor Analysis of Post-tonsillectomy Hemorrhage in an Adult Population: An Experience From a National Ear, Nose, and Throat (ENT) Center in Georgia

BACKGROUND

Tonsillectomy, a common surgical procedure for removing the palatine tonsils, is frequently performed in the otorhinolaryngology department. Tonsillectomy, with or without adenoidectomy, is considered a straightforward operation. However, serious complications, such as post-tonsillectomy hemorrhage, can complicate the recovery period. The research aims to analyze and estimate the factors associated with postoperative bleeding in the adult Georgian population.

METHOD

We conducted a cross-sectional study. The data was collected retrospectively from the medical records of adult patients aged 18 years and older, who underwent tonsillectomy in 2022 and 2023 at the National Center of Otorhinolaryngology, Japaridze-Kevanishvili Clinic, in Georgia. We performed univariate analysis using binary logistic regression and multivariate logistic regression analysis and calculated odds ratio (OR) to identify factors associated with postoperative bleeding among patients with tonsillectomy. A p-value of <0.05 was considered statistically significant.

RESULTS

A total of 778 adult patients with tonsillectomy were included in the study. Post-tonsillectomy hemorrhage occurred in 14.7% (n=114) of cases, with primary bleeding observed in 8.1% (n=63) of patients and secondary bleeding in 6.6% (n=51) of cases. The highest incidence of bleeding was observed on days 1 (8.1%, n=63) and 7 (1.3%, n=10). The statistical analysis revealed a statistically significant association between post-tonsillectomy hemorrhage and several factors: smoking status (OR=10.1, 95% CI: 6.1-16.7, p<0.001) and having a body mass index (BMI) greater than 25 (OR=3.6, 95% CI: 2.1-6.1, p<0.001).

CONCLUSION

The study confirmed several significant risk factors, including smoking and higher BMI, that are associated with an increased risk of bleeding among patients, undergoing tonsillectomy. Further research is needed to validate these findings in the Georgian population.

Adult tonsillectomy-increased pain scores are correlated with risk of bleeding: a retrospective cohort study

PURPOSE

Tonsillectomy is among the most common surgical procedures performed worldwide, and post-tonsillectomy bleeding is a serious complication. This study aims to investigate the role of post-operative pain as a risk factor for bleeding in adults.

METHODS

A retrospective cohort study of adults who underwent tonsillectomy in a tertiary referral center between 2015-2021. Medical records were reviewed for demographics, diagnoses, surgical technique, treatments, pain scores (measured by visual analogue scale 0-10), readmissions, and bleeding events. The primary outcome was return to the operating room for hemostasis, and secondary outcomes were bleeding events and consumption of additional analgesic doses.

RESULTS

Of the 274 patients, 137 (50%) were males, the mean age was 30.3 ± 12 years (range 18-82), and 33 (12%) were smokers. Indications for tonsillectomy were recurrent throat infections in 213 (77.7%) patients and obstructive sleep apnea in 61 (22.3%). Surgical technique was cold dissection in 238 (86.9%) patients and electrocautery in 36 (13.1%). Primary post-tonsillectomy bleeding (< 24 h of surgery) occurred in 6 (2%) patients, and secondary bleeding (later than 24 h from tonsillectomy) in 43 (15.7%). A total of 19 (7%) patients necessitated surgical hemostasis. After controlling for technique and other confounders, high pain scores (VAS ≥ 5) on post-operative days 1 and 2 were associated with increased risk of bleeding that necessitated surgical hemostasis (adjusted odds ratio 6.9, 95% confidence interval 1.7-44.5). Other independent risk factors were male sex, age < 30 years, smoking, and recurrent throat infections.

CONCLUSIONS

Higher pain scores following tonsillectomy are correlated with bleeding episodes requiring surgical intervention in adults. Further studies may explore the role of different intensive pain regimens in minimizing the risk of bleeding.

Adult tonsillectomy: An evaluation of indications and complications

OBJECTIVE

This study aimed to evaluate current adult tonsillectomy indications along with risk factors associated with postoperative complications.

METHODS

In this retrospective chart review, demographic, clinical, and surgical data were collected from 2004 to 2020 of adult patients who underwent tonsillectomy. Indications for surgery were categorized as infectious etiology, biopsy, obstructive sleep apnea (OSA), and tonsillar stones. Data regarding postoperative hemorrhage, emergency department (ED) visits, and readmissions were collected. Multivariable logistic regression models were used to evaluate factors associated with postoperative complications.

RESULTS

574 adults (mean age 32 years, 69.9% F vs. 30.1% M) were included. The most common indication was infections (62.2%), followed by biopsy (26.5%), tonsillar stones (6.8%), and OSA (4.5%). The highest frequency of postoperative bleeds (17.9%) occurred in the tonsillar stones cohort; however, the indication for surgery was not a significant predictor on multivariate analysis. Male sex and younger age were independent predictors of postoperative bleeding, while younger age was a significant predictor of postoperative ED visits. There was a significant linear trend of an increasing proportion of tonsillectomies performed for tonsillar stones compared to other indications for 2011-2019.

CONCLUSION

Infectious etiology was the most common indication for tonsillectomy. Indication for surgery was not a significant predictor of postoperative bleeding; however, male sex and younger age had higher odds of postoperative bleeding. The proportion of tonsillectomies performed for tonsillar stones was steadily increasing.

Radiographic Detection of the Relationship between Tonsilloliths and Dental Plaque-Related Pathologies in a Series of Digital Panoramic Radiographs

OBJECTIVE

The purpose of this study was to analyse the prevalence of tonsilloliths and to determine radiographically whether there is a relationship between tonsilloliths and dental plaque-related pathologies in a series of digital panoramic radiographs.

MATERIALS AND METHODS

This retrospective study included digital panoramic radiographs of 859 patients admitted for routine dental examination. The panoramic images were examined for both the presence of tonsilloliths and the number of decayed, missing, restored teeth and apical periodontitis. Periodontal bone loss was also measured in thirds of optimal bone height according to the root length and a percentage of bone loss was obtained for each panoramic radiograph evaluated.

RESULTS

Tonsilloliths were observed in 141 (16.4%) of all individuals. While there was no significant difference regarding the number of decayed teeth and restored teeth between tonsillolith cases (TT) and cases without tonsillolith (TC), the number of missing teeth and apical periodontitis in TT was significantly higher than TC (p: 0.004, p: 0.030, respectively). There was a significant difference between the groups in terms of the mean percentage of bone loss (p: 0.001; p < 0.05). In addition, cases showing bone loss between one-third and two-thirds of the optimal bone height in the TT group (52.5%) were significantly higher than those in TC (45.5%) (p: 0.035; p < 0.05).

CONCLUSION

The relationship between dental plaque-related pathologies and tonsilloliths observed in this retrospective study should be confirmed by computed tomography studies and randomized, prospective, clinical trials conducted in a multidisciplinary manner.

The impact of second-hand smoke on ear, nose, and throat diseases and head and neck cancers in Japan: a cross-sectional study using a questionnaire and secondary data from the national health and nutrition survey

BACKGROUND

The risk of head and neck cancers (HNCs) and ear, nose, and throat (ENT) diseases due to second-hand smoke (SHS) have not been fully assessed.

OBJECTIVE

To determine which ENT diseases or HNCs are associated with SHS.

MATERIAL AND METHODS

Data from a survey of a cross-sectional sample of ENT patients (n = 1228) on SHS exposure were compared to control-subject data (n = 6598) from a Japan National Health Survey. Multivariate logistic regression and estimated odds ratios (ORs) determined whether SHS-disease associations were related to exposure location and disease occurrence.

RESULTS

SHS was significantly associated with acute tonsillitis (OR in workplaces, 2.24 [95% CI, 1.34-3.75]; OR in restaurants, 4.24 [95% CI, 2.50-7.19]; OR in leisure places, 4.72 [95% CI, 2.93-7.62]); recurrent tonsillitis (OR in restaurants, 4.24 [95% CI, 2.52-7.13]; OR in leisure places, 5.29 [95% CI, 3.31-8.46]); facial palsy (OR in home, 2.18 [95% CI, 1.25-3.81]; OR in leisure places, 3.41 [95% CI, 1.97-5.89]); hypopharyngeal cancer (OR in home, 2.51 [95% CI, 1.18-5.36]; OR in workplaces, 2.53 [95% CI, 1.24-5.15]); and laryngeal cancer (OR in home, 2.44 [95% CI, 1.04-5.68]; OR in leisure places, 2.25 [95% CI, 1.00-5.07]).

CONCLUSIONS AND SIGNIFICANCE

SHS may contribute to HNCs and ENT diseases, suggesting that merely being in the presence of smokers could increase the risk of head and neck morbidities.

Risk factors of post-tonsillectomy hemorrhage in adults

OBJECTIVE

Tonsillectomy is an essential surgery and is conducted on both children and adults. However, the risk factors of post-tonsillectomy hemorrhage for adult patients remain unclear. In this study, we analyzed post-tonsillectomy hemorrhage in adult patients.

METHODS

We retrospectively analyzed 325 adult patients who underwent a tonsillectomy between 2014 and 2018 in our facilities.

RESULTS

The average age of this study's population was 31.7 ± 10.5 years (range: 19-70 years), and 250 (76.9%) patients were male. Overall, post-tonsillectomy hemorrhage occurred in 71 (21.8%) patients and 5 (1.5%) patients required a second surgery for hemostasis. Post-tonsillectomy hemorrhage often occurred on postoperative day zero or six. Using multiple logistic regression analysis, current smoking status (odds ratio 3.491; 95% confidence interval 1.813-6.723), male sex (odds ratio 3.924; 95% confidence interval 1.548-9.944), and perioperative non-steroidal anti-inflammatory drug administration (odds ratio 7.930; 95% confidence interval 1.004-62.64) were revealed as overall post-tonsillectomy hemorrhage risk factors. To analyze the hemorrhage period after tonsillectomy, we categorized the post-tonsillectomy hemorrhage patients into the primary (bleeding within postoperative day one) and secondary hemorrhage (bleeding on or after postoperative day two) groups. The current smoking status and older age were risk factors for primary hemorrhage and the current smoking status and sex (male) were risk factors for secondary hemorrhage.

CONCLUSIONS

In this study, smoking status, sex, and perioperative non-steroidal anti-inflammatory drug administration were the clinical risk factors for adult post-tonsillectomy hemorrhage. Thus, smoking cessation is, at least, mandatory for patients who receive tonsillectomy to avoid post-tonsillectomy hemorrhage.

Smoking and risk of surgical bleeding: nationwide analysis of 5,452,411 surgical cases

BACKGROUND

Although smoking is associated with several postoperative complications, a possible association with surgical bleeding remains unclear. We examined if smoking is associated with a higher risk of surgical bleeding.

STUDY DESIGN AND METHODS

We included patients from the American College of Surgeons National Surgical Quality Improvement Program 2007-2016 from 680 hospitals across the United States. Patients with information on age, sex, surgical specialty, and smoking status were included. Surgical bleeding was defined as 1 or more red blood cell (RBC) units transfused intraoperatively to 72 hours postoperatively. The association between smoking and surgical bleeding was examined using logistic regressions adjusted for age, sex, body mass index, ethnicity, comorbidities, laboratory values, American Society of Anesthesiologists score, type of anesthesia, duration of surgery, work relative value unit (surrogate for operative complexity), surgical specialty, and procedure year.

RESULTS

A total of 5,452,411 cases were recorded, of whom 19% smoked and 6% received transfusion. Odds ratios for transfusion were 1.06 (95% confidence interval [CI], 1.05-1.07) for smokers versus nonsmokers and 1.06 (95% CI, 1.04-1.09) for current smokers versus never-smokers. Odds ratios for cumulative smoking were 0.97 (95% CI, 0.95-1.00) for greater than 0 to 20 versus 0 pack-years, 1.04 (95% CI, 1.01-1.07) for greater than 20 to 40, and 1.12 (95% CI, 1.09-1.15) for greater than 40 (p for trend < 0.001). Hazard ratios for reoperations due to any cause and to bleeding were 1.28 (95% CI, 1.27-1.31) and 0.99 (95% CI, 0.93-1.04).

CONCLUSION

Smoking was associated with a higher risk of RBC transfusion as a proxy for surgical bleeding across all surgical specialties combined.

Appendectomy, Tonsillectomy and Parkinson's Disease Risk: A Swedish Register-Based Study

Introduction: The gut-brain hypothesis proposes that Parkinson's disease (PD) pathology may start in the gut and later spread to the brain in a prion-like manner. As PD pathology is redundant in the appendix and tonsils, which are important gut-associated lymphoid tissues, we examined whether appendectomy and tonsillectomy were associated with later PD risk. Methods: The nested case-control study included 78,650 PD patients born in 1900-1980 and with a diagnosis of PD between 1964 and 2010. For each PD patient, we randomly selected 40 non-PD controls individually matched for sex and year of birth at the date of PD diagnosis. Appendectomy and tonsillectomy before PD diagnosis were ascertained from the Swedish Patient Register from 1964 onward. We calculated odds ratios (OR) with 95% confidence intervals (CI) using conditional logistic regression adjusting for country of birth, highest achieved education, COPD, comorbidity index, and number of hospital visits. Results: Overall, we found 16% lower risk of PD linked to previous appendectomy (OR = 0.84, 95% CI: 0.80-0.88) and 8% lower risk of PD linked to previous tonsillectomy, although not statistically significant (OR = 0.92, 95% CI: 0.81-1.04). A 7 and 15% lower risk of PD was also noted ≥20 years after appendectomy and tonsillectomy, respectively. Similar associations were observed for men and women but were stronger for PD diagnosed after age 60. Conclusion: Appendectomy and potentially also tonsillectomy were associated with a lower risk PD. A potential mechanism may involve surgical removal of alpha-synuclein redundancy in the appendix and tonsils.

Increased Risk of Inflammatory Bowel Disease in Families with Tonsillectomy: A Danish National Cohort Study

BACKGROUND

The possible etiologic link between tonsillectomy and inflammatory bowel diseases remains unclear. To investigate the hereditary component, we assessed the risk of inflammatory bowel disease after own tonsillectomy as well as after tonsillectomy among family members.

METHODS

A nationwide Danish cohort of 7,045,288 individuals was established and linked to comprehensive national registers with data on kinship, tonsillectomy surgery, and diagnosis of inflammatory bowel disease from all health sectors. We used Poisson regression models to estimate hospital contact rate ratios (RR) for Crohn's disease and ulcerative colitis, with 95% confidence intervals (CI), between individuals with or without tonsillectomy, as well as between individuals with or without tonsillectomized relatives.

RESULTS

During 189 million person-years of follow-up between 1977 and 2014, 276,673 individuals were tonsillectomized, 22,015 developed Crohn's disease, and 49,550 developed ulcerative colitis. Rates of inflammatory bowel disease were elevated up to 20 years after own tonsillectomy (Crohn's disease: RR 1.52 [95% CI = 1.43, 1.61]; ulcerative colitis: RR 1.24 [95% CI = 1.18, 1.29]). RRs for Crohn's disease was 1.22 (95% CI = 1.17, 1.27) after first-degree relatives' tonsillectomy, 1.14 (95% CI = 1.08, 1.19) after second-degree relatives' tonsillectomy, and 1.08 (95% CI = 1.01, 1.15) after third-degree relatives' tonsillectomy. Corresponding RRs for ulcerative colitis were 1.10 (95% CI = 1.07, 1.13), 1.05 (95% CI = 1.01, 1.08), and 1.03 (95% CI = 0.98, 1.09).

CONCLUSIONS

Even individuals with tonsillectomized family members were at increased risk of inflammatory bowel disease. These findings call into question a direct influence of tonsillectomy on gastrointestinal inflammation and point instead toward shared hereditary or environmental factors.

Tonsillectomy and risk of Parkinson's disease: A danish nationwide population-based cohort study

BACKGROUND

We hypothesized that tonsillectomy modifies the risk of PD.

OBJECTIVES

To test the hypothesis in a nationwide population-based cohort study.

METHODS

We used Danish medical registries to construct a cohort of all patients in Denmark with an operation code of tonsillectomy 1980-2010 (n = 195,169) and a matched age and sex general population comparison cohort (n = 975,845). Patients were followed until PD diagnosis, death, censoring, or end of follow-up 30 November 2013. Using Cox regression, we computed hazard ratios for PD and corresponding 95% confidence intervals, adjusting for age and sex by study design, and potential confounders.

RESULTS

We identified 100 and 568 patients diagnosed with PD among the tonsillectomy and general population comparison cohort, respectively, finding similar risks of PD (adjusted hazard ratio = 0.95 [95% confidence interval: 0.76-1.19]; for > 20 years' follow-up (adjusted hazard ratio = 0.96 [95% confidence interval: 0.64-1.41]).

CONCLUSION

Tonsillectomy is not associated with risk of PD, especially early-onset PD. © 2017 International Parkinson and Movement Disorder Society.
