Introducere. Multiple studii demonstrează că în apariţia recidivelor joacă un anumit rol diferiţi factori, elucidarea acestora prezintă o importanţă majoră, deoarece sursa numeroaselor maladii cronice la adolescenţi şi maturi este vârsta copilăriei ce permite prognozarea dezvoltării recidivelor. Scopul lucrării. Studierea cauzelor recidivării procesului inflamator rinosinuzal la pacienţii cuprinşi în studiu. Material şi metode. Studiul ‒ 120 pacienţi (8-17 ani) cu patologie inflamatorie rinosinuzală. S-au analizat factorii care ar fi putut influenţa dezvoltarea recidivelor indiferent de metoda de tratament chirurgical aplicată. Analiză selectivă a tuturor factorilor locali şi generali au evidenţiat un grup de factori care se deosebeau semnificativ de grupul cu recidive comparativ cu cel fără recidive. 105 copii nu au avut recidive, 15 au prezentat cel puţin o recidivă. Rezultate. La pacienții cu recidive s-au stabilit următorii factori de risc: afecțiuni cronice rinosinuzale la parinți/rude 33%, reacţii alergice la părinţii/ rude 66%, maladiile infecţioase contagioase (infantile) şi bacteriene 93%, afecţiunile organelor ORL în anamneză 66%, variante anatomice şi anomalii rinosinuzale 53,3%, durata afecţiunii inflamatorii rinosinuzale 16,67±1,02 luni, cu o diferenţă stastistică p<0,05. Analiza discriminanta, in baza evaluării parametrilor enumeraţi, permite prezicerea absenţei recidivei cu o probabilitate de 89,52% şi apariţia recidivei cu o probabilitate de 86,67%. Concluzii. Studiul efectuat a permis determinarea celor mai informativi factori de cronicizare a sinuzitelor recidivante, evidenţierea grupului de risc sporit pentru dezvoltarea sinuzitelor cronice, aprecierea cauzelor recidivării.

Introduction. Many studies have revealed a number of different factors influencing the recurrence of chronic rhinosinusitis inflammatory process. It is crucial to establish such factors, as the source of various chronic diseases in teenagers and matures is the childhood age, which allows predicting potential recurrences. Objective of the study. Studying the causes of recurrence of chronic rhinosinusitis inflammatory process in the patients covered by the study. Material and methods. This study was conducted on 120 patients (aged between 8 and 17) with inflammatory rhinosinusitis disorder. The factors that could influence the recurrence, regardless of the surgical treatment used, were analyzed. After a selective analysis of all local and general factors, a group of factors was identified, which were significantly different in the group of people with recurrences as compared to the group without recurrences. 105 children did not have any recurrence and 15 had at least one recurrence. Results. In the patients with recurrences, the following risk factors were identified: chronic rhinosinusitis disorders in parents/relatives – 33%, allergic reactions in parents/relatives – 66%, contagious infections (in infants) and bacterial disorders – 93%, disorders of ENT organs in anamnesis – 66%, anatomical variations and rhinosinusal anomalies – 53.3%, length of sinonasal inflammatory disorder – 16.67±1.02 months, with a statistical difference of p<0.05. Discriminatory analysis based on evaluation of the above-listed criteria allows predicting the absence of recurrence with a probability rate of 89.52% and the appearance of recurrence with a probability rate of 86.67%. Conclusions. The study conducted has allowed establishing the most informative factors contributing to chronicization of recurrent sinusitis, identifying the group with high risk of developing chronic sinusitis, as well as determining the causes of recurrence.
