Abstract
The purpose of this study was to present surgical techniques for the reconstruction
of medial canthal defects with and without the involvement of the eyelid. This study
included 31 patients who underwent medial canthal reconstruction after tumor excision
during a 6-year period. Data regarding patient demographics, defect size, tumor pathology,
surgery techniques, functional and cosmetic outcomes, and complications were recorded.
The reconstructive methods used in the study were divided into groups as per the site
of the defect (medial canthal, medial canthal with upper eyelid, medial canthal with
lower eyelid, and medial canthal with both eyelids). The most common histopathological
diagnosis of the lesions was basal cell carcinoma (74.2%). Postoperative complications
(6.4%) included flap necrosis in one patient and lid margin notching in another. Among
patients who underwent reconstruction, 8 (25.8%) had only medial canthal defect, 6
(19.3%) had medial canthal defect extending to the upper eyelid, 7 (22.6%) had medial
canthal defect extending to the lower eyelid, and 10 (32.3%) had medial canthal defect
extending to both the eyelids. The functional outcome was regarded as normal in 30
(96.8%) patients and limited in 1 (3.2%) patient. Cosmetic outcomes were satisfactory
in all the patients. The use of alternative reconstructive approaches for different
subunits of the medial canthus is an efficient method to achieve superior functional
and cosmetic outcomes.
