Study summary

This study aims to evaluate the feasibility and preliminary biocompatibility of a novel lactoferrin-based ventilation tube and its manufacturing process for use in implantable medical materials. Patients with otitis media with effusion who are scheduled to undergo tympanostomy tube placement will be enrolled. Before insertion of the standard ventilation tube, the novel lactoferrin-based tube will be temporarily placed at the tympanic membrane incision site. Its handling characteristics and preliminary material properties will be assessed, including successful placement, mechanical strength, and structural integrity during manipulation. Local reactions of the tympanic membrane and surrounding tissues following brief contact will also be observed. The findings will provide preliminary evidence to support further material optimization and subsequent studies. This study is not intended to evaluate the long-term clinical efficacy or safety of the tube as an indwelling tympanostomy device.

Inclusion criteria

  • Adults aged ≤65 years
  • Clinically diagnosed with secretory otitis media, with no improvement after conservative treatment (e.g., pharmacotherapy, Eustachian tube inflation) for ≥3 months, and meeting the clinical indications for tympanostomy tube insertion
  • Intact tympanic membrane in the affected ear, without old perforation or acute infection
  • Provision of informed consent and voluntary participation, with the subject or legal guardian understanding and signing the written informed consent form

Exclusion criteria

Exclusion Criteria:

  • Ear structural abnormalities: including external auditory canal malformation, middle ear malformation, inner ear malformation, or a history of prior ear surgery that may affect tube placement
  • Acute illness or infection within 4 weeks before enrollment: in the acute infection phase such as pneumonia or influenza, or in the recovery phase of acute trauma or surgery
  • Presence of craniofacial deformities such as cleft palate
  • Allergy history: known allergy to dairy products, lactoferrin, or other protein components, or a history of severe allergic disease
  • Coagulation disorders: currently using anticoagulant drugs, or presence of coagulation abnormalities
  • Severe systemic diseases: including uncontrolled hypertension, diabetes, heart disease, severe hepatic or renal failure, immunocompromise or immunodeficiency (receiving immunosuppressive therapy, patients with advanced malignancy, patients with AIDS, etc.)
  • Special physiological conditions: pregnant or lactating women
  • Other circumstances unsuitable for study participation: including psychiatric disorders, cognitive impairment, drug or alcohol dependence, inability to cooperate with follow-up, or other medical or social factors judged by the investigator to make participation in this study inappropriate

Interventions

  • DeviceVentilation tube insertion

    A novel lactoferrin-based ventilation tube will be temporarily placed at the tympanic membrane incision site for approximately 10 minutes before routine tympanostomy tube insertion. Placement feasibility, material integrity, handling characteristics, and local tissue responses will be assessed.

What researchers measure

Primary outcomes

  1. Number and Percentage of Participants at Each Score on the Study-Defined 5-Point Intraoperative Feasibility Scale for Placement and Removal of the Lactoferrin Tympanostomy Tube

    For each participant's single study ear, placement and removal will be rated separately on the same study-defined 5-point ordinal scale: 1 (very smooth), first-attempt success without additional manipulation; 2 (basically smooth), first-attempt success with minor adjustment; 3 (partially impeded), success after 2-3 attempts or minor instrument assistance; 4 (difficult), success only after changing instruments, enlarging the tympanic membrane incision, or 4 or more attempts; 5 (failed), unable to complete placement or removal. Lower scores indicate better feasibility. If removal is not attempted because placement failed, removal will be not applicable and will not be imputed.

    Time frame: From the first attempt at tympanostomy tube insertion to 10 minutes after the successful placement of the tube.

  2. Number and Percentage of Participants With Any New or Worsened Tympanic Membrane Local Reaction During Temporary Intraoperative Use of the Lactoferrin Tympanostomy Tube

    For the single study ear of each participant, the investigator will assess tympanic membrane hyperemia, edema, bleeding, exudation, and any other local reaction after attempted placement, during the temporary dwell period, and immediately after tube removal. A participant will be counted once as having the outcome if at least one reaction is newly observed or worsens from the pre-placement assessment. The number and percentage of participants meeting this definition, with a two-sided 95% exact Clopper-Pearson confidence interval, will be reported using the safety analysis set, defined as all participants in whom placement of the lactoferrin tympanostomy tube is attempted. Each reaction type and severity will also be summarized separately. Multiple reaction types in the same participant will count once in the overall incidence.

    Time frame: From the first attempt at tympanostomy tube insertion to 10 minutes after the successful placement of the tube.
