Objectives: To evaluate the loss of quality of life (QoL) in patients with chronic obstructive sialadenitis (COS) using the Chronic Obstructive Sialadenitis Questionnaire (COSQ). Methods: The COSQ was administered to patients diagnosed with COS, with the diagnosis confirmed by sialendoscopy. Epidemiological data, obstructive causes and potentially obstructive entities were collected. QoL was assessed using the COSQ. Results: A total of 344 glands in 278 patients with COS were analyzed. Most patients were women (71.94%), and the main obstructive cause was stenosis (47.96%), followed by lithiasis, lack of papilla distensibility (LPD), and mucus plug. Stenosis was significantly more frequent in the parotid gland and in women, whereas lithiasis predominated in the submandibular gland and in men. The mean COSQ score was 30.55 and it was significantly higher in women (p < 0.005), parotid gland (p < 0.005), and in long-standing cases (p < 0.05). Stenosis and LPD were the obstructive causes with the greatest impact on QoL (p < 0.005), while lithiasis had the least impact. Potentially Obstructive Entities (POEs), such as eosinophilic sialodochitis, Sjögren’s syndrome, or radioiodine-induced sialadenitis, were associated with a notable loss of QoL. Likewise, patients without associated POEs presented significantly lower COSQ values (p < 0.05). Conclusions: COS significantly affects QoL, particularly in women and in cases of parotid gland, stenosis, and LPD. Lithiasis has the least impact on QoL. It is important to standardize a thorough evaluation of COS using validated tools such as the COSQ, which are fundamental for understanding the disease and predicting the outcomes of therapeutic interventions.

Eosinophilic sialodochitis is an under-recognized obstructive inflammatory disorder of the major salivary ducts that has been described under heterogeneous terms, including allergic parotitis, fibrinous sialodochitis, and Kussmaul disease. We systematically reviewed the literature to summarize nomenclature, clinical presentation, diagnostic assessment, treatment, and consistency with proposed diagnostic criteria. We searched six bibliographic databases from inception to December 2025, complemented by Google Scholar and citation tracking. Studies describing eosinophilic sialodochitis or related entities were included irrespective of language. Data were synthesized descriptively because of marked heterogeneity. Seventy-nine studies involving 387 patients were included, comprising 64 full-text reports and 15 conference abstracts or posters. Most publications were case reports or case series. Recurrent parotid and/or submandibular swelling, eosinophil-rich salivary mucus plugs, ductal dilatation or stenosis, and frequent atopic comorbidity were the most characteristic findings. Eosinophils were identified in salivary mucus in 53 of 58 studies reporting local samples. Full compliance with published diagnostic criteria varied markedly, from 45 of 79 studies using the Baer framework to 2 of 79 using the Carey framework, while no study fully satisfied the Zhao framework. Treatment was usually multimodal and included antihistamines, corticosteroids, intraductal irrigation, sialendoscopy-assisted procedures, and, in selected refractory cases, biologic agents targeting type 2 inflammation. The available evidence supports eosinophilic sialodochitis as a distinct but incompletely standardized clinicopathological entity. Interpretation is limited by heterogeneity, incomplete reporting, and low-certainty evidence. Standardized definitions and minimum reporting items are needed to improve diagnostic certainty and comparability.

Background: Reconstruction of nasal, septal, and nasosinusal defects is challenging when the native mucosa is absent or damaged. Oral mucosal grafts have been proposed as a reconstructive option due to their favorable biological properties, but their use in rhinology remains poorly defined. Objective: To evaluate the clinical efficacy and technical characteristics of oral mucosal grafting for nasal, septal, nasosinusal, and skull base reconstruction. Data Sources: PubMed, Embase, Web of Science, and Cochrane Library were searched for studies published between January 2005 and May 2025. Study Eligibility Criteria: We included original human studies (case reports or series) reporting the use of free or pedicled oral mucosal grafts in nasal, septal, nasosinusal, or skull base reconstruction. Non-original studies, animal or preclinical studies, and articles not in English or Spanish were excluded. Methods of Review: One reviewer screened titles, abstracts, and full texts using Rayyan. Methodological quality was assessed using JBI tools for case reports and case series. A narrative synthesis was conducted due to clinical heterogeneity and absence of comparison groups. The resulting assessments were reviewed by the co-authors to confirm accuracy and resolve any potential discrepancies. Results: Of 467 records identified, 10 studies were included. All were case reports or series involving buccal, palatal, or labial mucosa. Most reported good graft integration, low complication rates, and favorable functional outcomes. No randomized studies or comparative analyses were found. Limitations: Included studies had small sample sizes, lacked control groups, and showed heterogeneous methods and follow-up. The certainty of evidence could not be formally assessed. Conclusions: Oral mucosal grafting is a promising reconstructive option in selected nasosinusal and skull base defects. However, stronger comparative studies are needed to determine its clinical superiority. Registration: This review was not registered in any public database.

Chronic Obstructive Sialadenitis (COS) is a debilitating condition characterized by recurrent inflammation of the salivary glands due to excretory obstruction, significantly impacting patients' quality of life (QoL). The COS Quality of Life Questionnaire (COSQ) has been validated to evaluate QoL in affected patients and to monitor changes post-treatment. This study included two patient groups with COS-affected glands. The first group of 342 patients completed the COSQ before minimally invasive surgery, while the second group of 215 patients completed both the COSQ and a Visual Analog Scale (VAS). Scores were analyzed and stratified into four severity categories: mild, moderate, severe, and very severe, based on COSQ outcomes. COSQ scores were distributed as follows: mild (12.87%), moderate (37.13%), severe (34.5%), and very severe (15.21%). A significant correlation was observed between COSQ and VAS scores, particularly in the moderate and severe categories. Stratification allowed for identification of patients with severe symptoms, aiding in tailored management. The COSQ effectively assesses QoL in COS patients and aids in stratifying severity. This stratification can guide clinicians in developing personalized treatment strategies, monitoring disease progression, and evaluating treatment outcomes.

Background: Septoplasty is a widely performed surgical procedure to correct nasal septal deviations and improve respiratory function. One of its most significant complications is septal perforation, which can severely impact the patient’s quality of life. This study evaluates the use of bovine pericardium grafts to enhance mucosal healing, thereby reducing the risk of postoperative septal perforation in cases with intraoperative bilateral mucosal defects. Methods: A retrospective study was conducted on patients who underwent septoplasty between January 2018 and January 2025 in whom bovine pericardium grafts were interposed due to the presence of bilateral opposing mucosal defects. Epidemiological and surgical variables were recorded, and outcomes and complications were analyzed. Results: Out of the 4151 septoplasties performed, 30 cases (0.72%) required bovine pericardium interposition. The mean patient age was 42.87 years. Postoperative absence of septal perforation was confirmed in 90% of cases, with only three postoperative perforations, all asymptomatic and approximately 2 mm in size. Complications were recorded in three patients (10%), all of which were resolved with conservative treatment and without sequelae. Conclusions: For the first time in routine surgical practice, bovine pericardium emerges as a viable option for preventing postoperative septal perforation in cases with bilateral opposing mucosal defects. With a high closure rate and a low incidence of adverse events, this material represents a promising tool in septal surgery.
