Objective: The objective of this study is to evaluate a steroid-embedded Terpolymers polymer implant of L-lactide and trimethynele carbonate (TCM) at the level of disease control in patients with eosinophilic and central compartment chronic rhinosinusitis (CRS) after placement of the endonasal device, compared to a control group (placebo). The secondary objectives of this study are to assess comfort, perception of improvement and satisfaction, as well as adverse events. Methods: A randomized controlled trial will be carried out, with a blinded participant, therapist and evaluator. Patients over 18 years of age, with chronic rhinosinusitis (CRS) who have already undergone endoscopic sinus surgery (CENS), but who do not have the disease under control and, therefore, with an indication for a new CENS, will be selected. Participants will come from the otorhinolaryngology outpatient clinic of the academic and public service of the University of São Paulo - USP. Eligible patients will receive either the Terpolymers L-lactide and trimethynele carbonate (TCM) polymer implant placement or the placebo polymer. The primary outcome will be the control of the symptoms of chronic uncontrolled rhinosinusitis that will be evaluated through the NOSE Questionnaire, a nasal endoscopic evaluation based on the Lund-Kennedy criteria and the SNOT-22 Questionnaire. The sample size calculation was performed based on a difference between the intervention and placebo groups of 30% for cases that achieved disease control, resulting in a sample of 36 participants (18 in each group). Data will be analyzed using mixed linear models.

Eligibility | Inclusion Criteria: - Patients with chronic rhinosinusitis undergoing endoscopic sinus surgery, but who do not have the disease under control. The uncontrolled disease and its respective classification regarding the degree of the disease will be carried out through 3 assessments: 1) Nose Obstruction Symptom Evaluation Questionnaire (NOSE) validated version in Portuguese; 2) nasal endoscopic evaluation; and, 3) Sino Nasal Outcome Test Questionnaire (SNOT-22). Through the NOSE questionnaire, the patient's disease will be classified as "Controlled", "Partially Controlled" or "Uncontrolled (Uncontrolled)". Any variation in the endoscopic evaluation score based on the Lund-Kennedy Criteria will be considered an alteration. And for the SNOT-22 Questionnaire, changes will be considered when the total score varies by at least 11 points. Patients who present these 3 alterations will be considered to have the 'uncontrolled disease' and, therefore, will be eligible for the study. Exclusion Criteria: - Patients with malformations, trauma and/or tumors in the nasal and paranasal sinuses will be excluded; - Patients with a history of recent nasal surgery up to 6 months previously, with glaucoma and cataracts. |

Primary | Nasal Obstruction | Nasal Obstruction, Sistemic medication and Endoscopy (NOSE) questionnaire. NOSE is a method of evaluating the clinical control of chronic rhinosinusitis and is based on the evaluation of three aspects: nasal obstruction, nasal endoscopy and the need for systemic medication (antibiotics or steroids).
The NOSE questionnaire consists of five questions concerning subjective assessment of the nasal obstruction within the past month. Each question can be answered usinga 5-point Likert scale from"0"(not a problem) up to"4"(severe problems with breathing). After addition of allitem values and multiplying the raw score with 5, severity of the patient's complaints can be scaled to range from 0 to 100. A score of 0 indicates no obstructivenasal problems and a score of 100 implies severe problems. |

Primary | Nasal Endoscopic Evaluation | The nasal endoscopic evaluation will be performed under topical anesthesia, with a rigid endoscope (4mm, 0° and/or 45°; Karl Storz) and its classification will be based on the Lund - Kennedy criteria. For this evaluation, each nostril is examined separately and three possible characteristics may be present, they are: polyps, nasal mucosa edema and/or secretion. For each evaluated characteristic, a score from 0 to 2 is assigned. For the evaluation of polyps, the score is applied as follows: 0=absent; 1=restricted to the middle meatus; and, 2=extension to nasal cavity. For the evaluation of nasal mucosa edema, the score is applied as follows: 0=absent; 1=mild or moderate edema; and 2= polypoid degeneration. For the evaluation of secretion, the score is applied as follows: 0=absent; 1=hyaline secretion; and, 2=mucopurulent or thick secretion. | Day 15 after intervention | |
Primary | Sino Nasal Outcome Test | Sino Nasal Outcome Test (SNOT-22) The SNOT-22 Questionnaire is a modification of the SNOT-20, with 2 additional items on nasal obstruction and problems with smell and taste. The questionnaire assesses 22 items related to nasal symptoms that can impact the patient's personal and social life. Each item can get a score ranging from 0 (least possible problem) to 5 (greatest possible problem). Thus, this questionnaire has a final score that can range from 0 to 110 points. In this study, a significant clinical improvement will be considered when there is at least a variation of 11 points from one assessment to another.23 The validity and reliability of the SNOT-22 have already been previously tested in Portuguese. | Day 15 after intervention | |

Secondary | Complete blood count | A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia.
A complete blood count test measures several components and features of your blood, including: Red blood cells, which carry oxygen White blood cells, which fight infection Hemoglobin, the oxygen-carrying protein in red blood cells Hematocrit, the proportion of red blood cells to the fluid component, or plasma, in your blood Platelets, which help with blood clotting |
