  • Further extensive, controlled studies are required to clarify standardized protocols and confirm the position of PDT in the treatment of tonsillitis. Research is needed to evaluate the long-term efficacy and safety of PDT in otorhinolaryngology. Studies are needed to investigate the use of PDT in combination with other therapeutic options, such as antibiotics and surgery.

    Photodynamic Therapy in Otorhinolaryngology: Current Evidence, Clinical Applications and Future Perspectives · 2026 · DOI

  • There is a need for further research on the use of PDT in otorhinolaryngology, particularly in the treatment of chronic and recurrent tonsillitis. The current evidence is limited by the heterogeneity in study design, population, and therapeutic regimen. There is a need for larger randomized trials to fully evaluate the efficacy and safety of PDT in otorhinolaryngology.

    Photodynamic Therapy in Otorhinolaryngology: Current Evidence, Clinical Applications and Future Perspectives · 2026 · DOI

  • The diagnosis of nasal polyps is complex and requires accurate diagnostic tools. The use of nasal nitric oxide as a diagnostic tool may be limited by its variability and lack of standardization.

    Role of Nasal Nitric Oxide in the Diagnosis of Epithelial Remodeling Types of Nasal Polyps · 2026 · DOI

  • The role of nasal nitric oxide in the diagnosis of epithelial remodeling types of nasal polyps has not been fully explored. There is a need for a non-invasive and accurate diagnostic tool for the diagnosis of nasal polyps.

    Role of Nasal Nitric Oxide in the Diagnosis of Epithelial Remodeling Types of Nasal Polyps · 2026 · DOI

  • Delayed healthcare-seeking behavior. Higher environmental exposure and outdoor activities. Limited understanding of the clinical and epidemiologic patterns in patients with orbital complications.

    A Descriptive Study of the Patients with Orbital Complication of Acute and Chronic Sinusitis · 2026 · DOI

  • The need for early diagnosis and timely intervention in orbital complications of sinusitis. The importance of understanding the clinical and epidemiologic patterns in patients with orbital complications.

    A Descriptive Study of the Patients with Orbital Complication of Acute and Chronic Sinusitis · 2026 · DOI

  • The study identifies a gap in understanding how sex- and gender-related differences in emotional burden among patients with chronic rhinosinusitis with nasal polyps are associated with sleep disturbance. The study aims to address this gap by examining the relationship between sex, sleep disturbance, and emotional distress.

    Gender Differences in Emotional Burden in Chronic Rhinosinusitis: The Role of Sleep-Related Impairment · 2026 · DOI

  • There is a lack of data on the frequency of clinical symptoms associated with incidental paranasal sinus anomalies on MRI brain in developing countries. The clinical significance of incidental paranasal sinus anomalies on MRI brain is not well understood.

    Frequency of Clinical Symptoms Associated With Incidental Paranasal Sinus Anomalies on MRI Brain in Patients Reporting to a Tertiary Healthcare Centre in Pakistan · 2026 · DOI

  • The study identifies a gap in the understanding of the clinical significance of middle turbinate variations in patients with sinonasal symptoms. The study highlights the need for further research on the role of anatomical variations in the development of sinonasal symptoms.

    Computed Tomographic Evaluation Of Middle Turbinate Variations And Their Clinical Significance In Patients With Sinonasal Symptoms · 2026 · DOI

  • The incidence rate for congenital midline sinus of the columellar base is not well documented in the medical literature. The etiopathogenesis of congenital midline sinus is uncertain.

    Congenital midline sinus of the columellar base and nasal septum: A case report and literature review · 2026 · DOI

  • The survey data are limited to clinic days and are thus temporally inconsistent. Daily sample sizes tend to be small. The study's results should be interpreted with caution due to small subgroup sample sizes.

    Climate and sino-nasal symptoms · 2026 · DOI

  • The impact of climate on sino-nasal symptomatology has received little scientific attention. There is a need for studies that examine the relationship between weather and sino-nasal symptoms. The current study aims to address this research gap.

  • There is a need for a simple, noninvasive, and low-cost method for assessing local inflammation in CRSwNP. Current diagnostic methods have limitations.

    Local inflammation as a determinant of recurrence in CRSwNP: the clinical value of nasal cytology · 2026 · DOI

  • Systemic indicators often provide only an indirect view of the inflammatory processes occurring within the airway mucosa. Local inflammatory patterns in chronic airway diseases may significantly diverge from systemic profiles. There is a need for a local biomarker that provides a direct view of the inflammatory processes occurring within the airway mucosa.
