“…In studies of adenoidectomy specimens, patients with CRS had a large percentage of their mucosal surface covered with biofilm formation as compared to only minimal coverage in those without CRS . Cultures from the adenoids and middle meatus taken at the time of surgery have been shown to have a high degree of correlation in children with CRS . One study looked at patients with nasal discharge undergoing adenoidectomy and found no correlation between adenoid size and Lund‐McKay score .…”

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases.Appropriate frame conditions provided, the respective procedures are safe and successful.These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery.The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinusoperation with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus.In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving.This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

“…Cultures were performed from swabs of the middle meatus and revealed S. pneumoniae in 50 %, H. infl uenzae in 40 %, M. catarrhalis in 34 %, S. aureus in 20 %, and Corynebacterium in 52 %. In a study of children with recurrent or chronic sinusitis, S. aureus was present in the middle meatus in 32 % of samples [ 16 ]. These studies indicate that the middle meatus is heavily colonized with pathogenic and nonpathogenic bacteria in healthy children.…”

IntroductionAn understanding of the microbiology of acute bacterial sinusitis in children is key to making decisions about antimicrobial selection. Most work in this area has focused on acute bacterial sinusitis, with fewer studies addressing subacute and chronic sinusitis in children. Since the routine use of conjugate pneumococcal vaccines in 2000 and the emergence of Streptococcus pneumoniae which were highly resistant to penicillin, there has been renewed interest in determining the microbiology and epidemiology of sinusitis. This chapter will focus primarily on the microbiology of acute sinusitis in children. Subacute and chronic sinusitis in children, which have received much less attention in the medical literature, will also be reviewed. Acute Bacterial Sinusitis Sinus AspirationThe challenge in obtaining material for culture is that the sinuses are a closed system accessible only through a mucous membrane that is highly contaminated with respiratory fl ora. Because of the invasive nature of sinus aspirates, this procedure has not been performed on humans with normal sinuses. The sterility of the sinus cavity has been established in healthy rhesus monkeys that have undergone sinus aspiration [ 1 ]. This sterile environment is maintained by the mucociliary apparatus of the sinus and by normal immune function.Aspiration of the maxillary sinus after sterilization of the mucous membrane of the nasal cavity is the most stringent method for obtaining culture material to avoid contamination. This procedure is performed by anesthetizing and sterilizing the nasal mucosa with a solution of 10 % cocaine (cocaine has antiseptic properties). A culture of the mucosa is performed to test sterility to ensure that effective antisepsis has been achieved. Puncture is performed with a sterile 16-gauge trocar positioned beneath the inferior nasal turbinate; the antral cavity is aspirated. If no material is returned, then the sinus is irrigated with non-bacteriostatic saline which is aspirated and sent for culture. A signifi cant growth of bacteria is considered ≥10 4 colony-forming units per milliliter [ 2 ]. Results must be expressed quantitatively to ensure that an organism is present in suffi cient number to represent a true pathogen and not a contaminating organism.The only sinus puncture studies performed in children to establish the microbiology of acute bacterial sinusitis were reported in the 1980s [ 3 , 4 ] (Table 5.1 ). Fifty children between the ages of 1 and 16 years who were suspected of having sinusitis were evaluated. Children were entered into the study based on clinical symptoms and abnormal plain radiographs of the maxillary sinuses. Sinus puncture was performed and aspirates were cultured aerobically and anaerobically and a Gram stain prepared. A total of 79 sinus aspirates were performed. At least one sinus had signifi cant growth in 51 of 79

Relationship between bacteriology of the adenoid core and middle meatus in children with sinusitis

Abstract: Apart from its effect on nasal airway patency, adenoidal tissue may function as a bacterial reservoir initiating and maintaining sinus infection in children. These study findings support a potential role for adenoidectomy in the treatment of chronic or recurrent paediatric sinusitis.
