    Summary

    This study introduces a novel middle meatal antrostomy technique for chronic sinusitis, offering a safe and effective alternative to traditional methods. The new approach ensures a wide, patent antrostomy opening, preventing closure and improving patient outcomes.

    Area of Science:

    • Otolaryngology
    • Surgical Innovation
    • Rhinosinusitis Treatment

    Context:

    • Endonasal sinus surgery is increasingly preferred for chronic sinusitis, particularly when combined with nasal allergies.
    • Traditional inferior meatal antrostomy for maxillary sinusitis can lead to ostial closure and deviate from normal sinus physiology.
    • Middle meatal antrostomy techniques have evolved, with previous methods involving the inferior turbinate or middle meatal wall.

    Purpose:

    • To present a new, safe, and easily performed technique for middle meatal antrostomy.
    • To describe a surgical approach that ensures adequate exposure and orientation of key anatomical structures.
    • To establish a reliable method for creating a wide antrostomy opening to prevent closure.

    Summary:

    • A novel technique involves mucosal incision and reflection of the inferior turbinate's mucous membrane to expose the frontal process of the maxilla, lacrimal bone, and inferior turbinate.
    • The pars membranacea is incised and removed with the uncinate process to access the maxillary antrum, creating a 1x1.5 cm opening.
    • The procedure was successfully applied to 34 patients with various sinonasal conditions, including sinusitis and polyps, with no reported complications or antrostomy closure.

    Impact:

    • This technique provides a valuable alternative for treating maxillary sinusitis and related conditions.
    • The described method potentially reduces the risk of antrostomy restenosis compared to older techniques.
    • Successful application in a diverse patient group suggests broad applicability in rhinosinusitis management.
