Purpose. To examine changes in the position of the lower eyelid punctum and tear meniscus height (TMH) after correction of horizontal laxity of the lower eyelid in involutional lower eyelid entropion. Methods. This prospective, observational study included 42 sides of 36 patients with involutional entropion who underwent a lateral tarsal strip procedure or transcanthal canthopexy (+ lower eyelid retractor advancement). The horizontal distance from the medial margin of the lower lacrimal punctum to the medial canthus was measured using ImageJ software. TMH was measured using anterior segment optical coherence tomography. All measurements were performed preoperatively, at postoperative 3-month and at postoperative 6-month. Results. The lower lacrimal punctum significantly shifted laterally at 3-month follow-up and slightly returned toward its original position at 6-month follow-up (Friedman’s test, P < 0.001 ). Although the differences did not reach statistical significance, TMH in the lower eyelid increased at 3-month follow-up and then slightly decreased at 6-month follow-up (Friedman’s test, P = 0.076 ). Conclusions. The results of this study imply that lateral shift of the lower lacrimal punctum prevents effective drainage of tears accumulated in the lacrimal lake, resulting in increased TMH after correction of horizontal laxity of the lower eyelid in involutional entropion.

In this prospective observational study, we aimed to examine improvements in horizontal laxity after lower eyelid retractor advancement and transcanthal canthopexy for involutional lower eyelid entropion. The study included 19 sides in 15 patients with involutional entropion who underwent transcanthal canthopexy with the advancement of the lower eyelid retractor. Using the pinch test, the distance from the lowest part of the corneal limbus to the eyelid margin was measured using callipers. All measurements were performed preoperatively and at postoperative 3 and 6 months. Using the pinch test, the distance from the lowest part of the corneal limbus to the lower eyelid margin was significantly shortened during each postoperative follow-up period. None of the included cases experienced recurrence. Our results indicated that transcanthal canthopexy could preserve postoperative horizontal tightness.

“…Increasing the demolition of anterior ethmoid, upper septum and frontal sinus floor may increase the chance for complications. The most frequently reported include orbital emphysema or hematoma, lachrymal sac injury, short or long-term hyposmia and/or anosmia, major bleeding from AEA [18] and CSFL associated with iatrogenic interruptions of the cribriform plate or posterior frontal sinus wall [6,19,20]. Therefore, accurate preoperative evaluation, adequate instrumentation confidence with relevant regional anatomy and endoscopic surgical expertise are warranted to perform such extensive endoscopic endonasal approaches.…”

Purpose of reviewDespite the impressive evolutions in endoscopic endonasal approaches and instrumentations, the frontal sinus remains a challenging area. Different surgical options have been described over the years, but the main criticism lies in choosing the most suitable approach for a given case, based on the anatomy of each patient and the disease to treat. The purpose of this study is to provide a comprehensive review of surgical access strategies currently available to address the frontal sinus, including both endonasal and traditional external procedures, analysing indications, contraindications, complications and outcomes. Recent findingsFrontal sinus surgery includes minimally invasive endonasal approaches (balloon dilatation, Draf type I); extended endonasal approaches (Draf type IIA-IIB-IIC, Draf type III and their modifications via orbital transposition and contralateral pyriform aperture resection); external procedures (superior eyelid incision, frontal osteoplastic flap, Riedel procedure, Riedel-Mosher operation); and combined approaches. SummaryRecent advances in endoscopic endonasal techniques have deeply reshaped the surgical options to manage frontal sinus diseases, in an attempt to minimize the invasiveness of the procedures and maximize their outcomes. Traditional external procedures should be used in selected cases nonamenable for endonasal surgery. The appropriate selection of cases appears to be of paramount importance to obtain successful outcomes.
