    Summary

    Computed tomographic dacryocystography aids in managing lacrimal obstruction after medial maxillectomy. This imaging technique helps rule out tumor recurrence and sinusitis, guiding surgical approaches in complex anatomical cases.

    Area of Science:

    • Ophthalmology
    • Radiology
    • Head and Neck Surgery

    Background:

    • Medial maxillectomy, a surgical procedure, can lead to complications such as lacrimal obstruction.
    • Lacrimal obstruction may necessitate further surgical intervention, like dacryocystorhinostomy.
    • Accurate diagnosis and surgical planning are crucial for managing post-maxillectomy complications.

    Observation:

    • Computed tomographic dacryocystography involves instilling radiopaque dye into the lacrimal sac followed by CT scanning.
    • This imaging modality was employed to evaluate a patient experiencing lacrimal obstruction post-medial maxillectomy.
    • The technique provided detailed visualization of the lacrimal system within the altered surgical anatomy.

    Findings:

    • Computed tomographic dacryocystography effectively excluded the possibility of recurrent tumor and sinusitis.
    • The procedure offered a clear surgical roadmap by delineating the anatomical structures.
    • This facilitated precise management of the lacrimal obstruction in a challenging post-operative setting.

    Implications:

    • Computed tomographic dacryocystography is a valuable tool for diagnosing and managing lacrimal system issues after maxillectomy.
    • It aids in differentiating between tumor recurrence, sinusitis, and other causes of obstruction.
    • The technique enhances surgical planning, improving outcomes for patients with complex post-maxillectomy anatomy.
