Background. Adenoid hypertrophy may cause sleep-disordered breathing and altered craniofacial growth. The authors conducted a study to gauge the accuracy of alternative tests compared with nasoendoscopy (reference standard) for screening adenoid hypertrophy. Methods. The authors conducted a systematic review that included searches of electronic databases, hand searches of bibliographies of relevant articles and gray literature searches. They included all articles in which an alternative test was compared with nasoendoscopy in children with suspected nasal or nasopharyngeal airway obstruction. Results. The authors identified seven articles that were of poor to good quality. They identified the following alternative tests: multirow detector computed tomography (sensitivity, 92 percent; specificity, 97 percent), videofluoroscopy (sensitivity, 100 percent; specifi city, 90 percent), rhinomanometry with decongestant (sensitivity, 83 percent; specificity, 83 percent) and clinical examination (sensitivity, 22 percent; specificity, 88 percent). Lateral cephalograms tended to have good to fair sensitivity (typically 61-75 percent) and poor specificity (41-55 percent) when adenoid size was evaluated but excellent to good specificity when airway patency was evaluated (68-96 percent). Conclusions. No ideal tool exists for dentists to screen adenoid hypertrophy, owing to access constraints, radiation concerns and suboptimal diagnostic accuracy. Research is needed to identify a low-risk, easily acceptable, highly valid diagnostic screening tool. Practical Implications. Although lateral cephalograms (which have good to fair sensitivity) and a thorough medical history (which has good specificity) are imperfect individually, when they are used together, they can compensate for each other's weaknesses. This combined approach is the best tool available to dentists for screening adenoid hypertrophy.

This article aimed to collectively present the demographic, clinical, radiographic and histopathological features as well as the treatment performed along with its outcome for all the cases of adenoid ameloblastoma with dentinoid (AAD) reported in scientific literature till date. Ameloblastoma and adenomatoid odontogenic tumours are the most common odontogenic neoplasms. However, AAD, a hybrid variant of the two lesions, is found to be extremely rare. The lesion comprises of characteristic histopathological features of ameloblastoma and adenomatoid odontogenic tumour and shares certain clinical characteristics with either of the entities. AAD may be considered to be present at the more aggressive end of spectrum of benign odontogenic neoplasms. Owing to the frequent tendency of the lesions to be underdiagnosed, careful histopathological screening of submitted biopsies is warranted. With the increase in number of reported cases in the recent years, it is likely to be included as a separate entity in the upcoming World Health Organization classification.

The adenoid is a bacterial reservoir that contributes to chronic otolaryngologic infections. Staphylococcus aureus (S. aureus) is a common pathogen in the adenoid. The increase of antibiotic resistance in S. aureus has become an important issue in public health. The aim of this study was to compare adenoid hyperplasia and biofilm formation in children with S. aureus adenoiditis in Taiwan. The patients were divided into methicillin-resistant and methicillin-sensitive S. aureus groups according to the S. aureus obtained from adenoid tissue after antibiotic susceptibility testing. Adenoid hyperplasia was assessed by lateral cephalometry, and the severity of sinusitis was evaluated by Water's view. Microbiological investigation of available S. aureus isolates was performed by in vivo morphological observation and an in vitro bacterial biofilm assay. Sixty isolates of S. aureus were identified in 283 children (21.2%) after adenoidectomy, of which 21 (35%) were methicillin-resistant S. aureus (MRSA). The severity of adenoid hyperplasia and extensive biofilm formation were more prominent in patients infected with methicillin-resistant S. aureus than in those infected with methicillin-sensitive S. aureus (MSSA). The primary outcome of this study was to provide evidence that S. aureus constituted a significant portion of the adenoidal pathogens. The secondary outcome of this study was that MRSA adenoiditis may be associated with adenoid hyperplasia and biofilm formation.

OBJECTIVE: The technique of adenoidectomy has undergone many refinements over the years with, most recently, the addition of electrosurgery alone as a viable method for removal of adenoid tissue. Several studies have suggested good efficacy with this method. The objective of this study is to examine the effectiveness of adenoidectomy by electrosurgical ablation by the following measures: reduction of the adenoid size, blood loss, and postoperative complications. DESIGN AND METHODS: In this prospective study, we reviewed patients who underwent electrosurgical adenoid ablation for either nasal obstructive symptoms or chronic otitis media with effusion requiring a second or greater set of pressure equalization tubes and adenoidectomy. Preoperative and postoperative videonasopharyngoscopy were performed and evaluated. A grading system for adenoid size for the endoscopic parameters was used. The amount of blood loss and postoperative complications were recorded. RESULTS: On preoperative nasopharyngoscopy, 7 of 23 children had a grade II adenoid size, 15 of 23 had grade III adenoid pads, and 1 of 23 had grade IV adenoid size. Postoperative follow-up at 6 to 8 weeks revealed that 19 of 23 children showed no evidence of adenoid tissue. Three of 23 children had only tiny residual tissue that fell into grade I and one had regrowth of tissue to fit into grade III. Eight patients were seen at 6 months postoperatively, four of whom were followed up to 12 months postoperatively; all showed no evidence of regrowth of adenoid tissue. Average blood loss for the procedure was 2.6 cc. No postoperative complications (postoperative bleed, dehydration requiring hospitalization, infection, velopharyngeal insufficiency) were encountered. CONCLUSIONS: Electrosurgical adenoid ablation is a safe method with minimal intraoperative blood loss and postoperative complications. Follow-up at 6 to 8 weeks and up to 1 year postoperatively suggests that it is an effective method in removing adenoid tissue and alleviating nasal obstruction.

Adenoid hypertrophy (AH) is an extremely common condition in the pediatric and adolescent populations that can lead to various medical conditions, including acute rhinosusitis, with a percentage of these progressing to chronic rhinosinusitis (CRS). The relationship between AH and pediatric CRS has been extensively studied over the past few years and clinical consensus on the treatment has now been reached, allowing this treatment to become the preferred clinical practice. The purpose of this study is to review existing literature and data on the relationship between AH and CRS and the options for treatment. A systematic literature review was performed using a search line for "(Adenoiditis or Adenoid Hypertrophy) and Sinusitis and (Pediatric or Children)". At the end of the evaluation, 36 complete texts were analyzed, 17 of which were considered eligible for the final study, dating from 1997 to 2018. The total population of children assessed in the various studies was of 2371. The studies were categorized as surgical-observational, microbiological, genetic-immunological, and radiological. The analysis of the studies confirms the relationship between AH and CRS and supports the existing consensus on medical and surgical therapy. Furthermore, these studies underline the necessity to adapt medical and surgical treatment considering age, comorbidities including asthma and, if present, the Computed Tomography (CT) score.

CONTEXT: Adenoids play an important role in the protection of the upper respiratory tract against pathogens. Nonphysiological enlargement of adenoids is defined as adenoid hypertrophy (AH). In treating AH, physicians prefer medical therapy and often disregard adjunctive methods. Studies on the effects of adjunctive methods on adenoid tissue are quite scarce. OBJECTIVE: The current review aims to examine the clinical studies that have investigated adjunctive methods-nasal irrigation, herbal therapy, bacteriotherapy, and halotherapy-used to treat AH and its associated symptoms and to evaluate their effectiveness in pediatric patients. DESIGN: The research team performed a narrative review by searching seven electronic databases (Pubmed, Cochrane Library, Google Scholar, Web of Science, EMBASE, Science Citation Index and Elsevier) were used for the literature search. The search used the keywords adenoid hypertrophy, adjunctive treatment, nasal irrigation, herbal medications, bacteriotherapy and halotherapy. SETTING: This study was took place in Department of Anatomy, Medicine Faculty, Istanbul Medeniyet University. RESULTS: The nasal irrigation with hypertonic solution decreased to size of enlarged adenoid tissue. The bacteriotherapy used with nasal spray and tablet form decreased to surgery rate and adenoid size.The adenoid and/or tonsillar hypertrophy were decreased by halotherapy used with micronized, iodized-salt aerosol. CONCLUSIONS: A review of studies on this matter indicates that the studied adjunctive methods can be used safely in the treatment of AH, either separately or in combination with conventional medical treatment. However further clinical studies are needed on this topic.

OBJECTIVE: Adenoid cystic carcinoma is a malignant minor salivary gland tumor that represents <1% of all laryngeal tumors. The submucosal location of laryngeal adenoid cystic carcinoma (LACC) results in delayed presentation. Here, we present the first systematic review of reported cases of LACC to determine trends in presentation, diagnostic and treatment modalities, and patient outcome. DATA SOURCES: PubMed, Web of Science, MEDLINE, and EMBASE databases. METHODS: A search of the above databases was done to identify articles reporting cases of LACC. The variables included in the analysis were patient demographics, presenting symptoms, tumor location, imaging, treatment, follow-up time, recurrence, and outcome. RESULTS: A total of 50 articles and 120 cases were included in the review. The most common presenting symptom was dyspnea (48.8%), followed by hoarseness (43.9%). LACC arose most frequently from the subglottis (56.7%). At presentation, 14.6% (13 of 89) of patients had regional disease. The average follow-up time was 54.0 months. At follow-up, distant metastasis was reported in 30 cases (33.3%). Surgery alone (43.3%) and surgery with radiotherapy (43.3%) were used most frequently and resulted in 57.1% and 55.3% of patients alive with no evidence disease at follow-up, respectively. CONCLUSION: LACC was most often located in the subglottis. Patients commonly presented with dyspnea and hoarseness. In this systematic review, surgery with radiotherapy and surgery alone were the most commonly employed treatment modalities, and both resulted in slightly more than 50% of patients alive with no evidence of disease at follow-up.

OBJECTIVES: Transient bacteremia is induced by adenoidectomy when the integrity of the nasopharyngeal membrane is broken. The aim of this study was to determine the incidence of bacteremia in patients undergoing adenoidectomy, to identify the causative organisms, and to compare the incidences of bacteremia between the two techniques suction diathermy and curettage. METHODS: A prospective single-blind randomized trial was performed. Sixty-four patients between the ages of 2 and 13 years who were undergoing adenoidectomy were included in the study. Exclusion criteria included antimicrobial therapy in the immediate preoperative period and concurrent respiratory tract infection or pyrexia. Patients were randomized in the anesthetic room to either suction diathermy or curettage. Venous blood samples for culture were obtained 30 seconds after the procedure began (intraoperative sample) and 2 minutes after removal of the adenoid tissue (postoperative sample). Postoperative complications were recorded, and all patients were followed in the outpatient department. RESULTS: Twenty-six patients underwent adenoidectomy by suction diathermy, and 38 underwent adenoidectomy by curettage. In the suction diathermy group, 38.5% of intraoperative and 19.2% of postoperative blood cultures had a positive result for bacteremia. In the curettage group, 31.6% of intraoperative and 23.6% of postoperative blood cultures had a positive result for bacteremia. There was no significant difference between the two groups. The techniques were equivalent in terms of postoperative complications. Gram-positive cocci were the most commonly isolated organisms. CONCLUSIONS: A transient bacteremia exists after pediatric adenoidectomy, but does not correlate with symptoms or signs. Neither suction diathermy adenoidectomy nor curettage adenoidectomy offers a particular advantage in terms of decreasing the incidence of bacteremia.
