Background: We aimed to find some new indicators for tonsillectomy (TE) in adults with recurrent tonsillitis (RT) by exploring whether the frequency of tonsillitis episodes and the length of morbidity period are associated with the macroscopic signs of sclerotic process in tonsils and microbiological data assessed by culture, molecular (PCR) and transmission electron microscopy (EM) methods.

The most common causes for failure of previous surgery were persistent mastoid cells in the tegmental, sinodural angle, and the retrolabyrinthine, retrofacial, and mastoid tip regions (100%); the bony overhangs at the edges of the mastoid cavity and the high facial ridge (98%); inadequately narrow meatus (84%); recurrent or residual cholesteatoma (46%); and remaining malleus head (40%). Revision surgery included elimination of all encountered limitations followed by mastoid cavity obliteration in about two-thirds of cases. Hearing restoration was done in only 34% of ears. In the remaining cases, intact ossicular chain (6%), existing sufficient previous reconstruction (22%) or impossible situation for reconstruction (38%) was found.

ObjectiveThe first aim of this study was to compare the microbiota of different locations (pus, tonsillar fossa, blood) in peritonsillar abscess (PTA) patients in order to optimize the sampling scheme. The second aim was to estimate the occurrence of tonsillitis episodes and macroscopic oropharyngeal signs characteristic of recurrent tonsillitis in PTA patients.MethodsThe study group consisted of 22 consecutive patients with PTA undergoing bilateral tonsillectomy. The PTA was punctured; pus and tonsillar fossa biopsy samples and the peripheral blood cultures were collected. The index of tonsillitis was calculated by multiplying the number of tonsillitis episodes per year by the morbidity period in years. Macroscopic oropharyngeal signs were evaluated and they were as follows: tonsillar sclerosis, obstruction of the tonsillar crypts, scar tissue on tonsils, cryptic debris, and lymphatic tissue aggregates.ResultsThe cultures of the pus were positive in 16 out of 22 patients and the cultures of the tonsillar fossa samples were positive in all cases. In total, 62 different organisms were found from tonsillar fossa, pus, and blood samples, which belonged to 5 different phyla and 18 different families.In the tonsillar fossa, the most frequent bacteria found were Streptococcus spp. In pus samples, the most frequently found bacteria were Streptococcus spp. and bacteria from the Streptococcus milleri group.ConclusionPTA patients had mixed anaerobic and aerobic microbiota both in the tissue of the tonsillar fossa and the pus of the peritonsillar space. We demonstrated that the tonsillar fossa specimen is a better material for microbiological analyses, because it reveals more bacteria per culture. PTA patients usually have a low number of tonsillitis episodes in their previous history, but a relatively high number of macroscopic oropharyngeal signs, indicating the sclerotic process in palatal tonsils.

The present study explored in adults suffering from recurrent tonsillitis the association between macroscopic oropharyngeal signs of recurrent inflammation, immunomorphology of palatine tonsils (counts of neutrophils by CD4 and macrophages by CD68 monoclonal antibodies in tonsillar microcompartments) and the occurrence of post-tonsillectomy bacteremia. The study involved 50 adults (31 females and 19 males) with recurrent tonsillitis. According to predominance of either inflammatory changes or evidence of sclerotic process in palatine tonsils and surrounding tissue macroscopic at oropharyngeal examination, the patients were divided into groups with 'inflammatory-type' and 'sclerotic-type' tonsils. Biochemically detected mean collagen content was significantly higher in 'sclerotic-type' tonsils than in 'inflammatory-type' tonsils (p=0.001). Post-tonsillectomy bacteremia was found in 22 patients (44%). A noteworthy finding was the higher recovery of anaerobes from blood cultures than in previous studies. A logistic regression analysis revealed that the post-tonsillectomy bacteremia was strongly associated with 'sclerotic-type' tonsils (p=0.0015) and with low counts of neutrophils in tonsillar tissue (p=0.047). We conclude that macroscopic oropharyngeal signs of sclerotic process in palatine tonsils indicate impaired tonsillar defense, in terms of lowered counts of neutrophils, increasing the risk of post-tonsillectomy bacteremia.
