This single-center, single-blind, parallel-design clinical study enrolled 72 healthy female volunteers, aged 35 to 72 years, with fine-to-moderate wrinkles in the lateral canthal
areas (crow feet).

The laxity of the lateral and medial canthal
tendon and false insertion of the lower retractors are the main causative factors of senile entropion [2,12].
The medial canthal
ligament plays an important role in maintaining shape and function of the eyelids.
It is designed on the lateral canthal
region, pedicled on orbicularis oculi and extending at the crow's feet in a "V" fashion.
The company said BOTOX Vista is now indicated for the temporary improvement in the appearance of lateral canthal

There is a labyrinth of connective tissues attached to Whitnall's tubercle and as patients age, there is laxity of the septum, retinaculum, and orbicularis; rounding of the lateral canthal
angle; and a negative intercanthal tilt that develops as the lateral canthus drops in relation to the medial canthus, said Dr.
The results of endoscopic endonasal DCR are not only encouraging, but are associated with many other additional advantages e.g., avoidance of facial scar, preservation of medial canthal
anatomy, better visualisation resulting in less intra- operative trauma and blood loss and reduced operative time.3,4 Due to these advantages, there is a gradual shift from external approach in favour of endonasal approach, but in Pakistan, external approach is still the norm.
Of those bilateral cases inferonasal corneoconjunctival dermoids were most frequently reported followed by nasal canthal
dermoids (Ismail 1993; Yeruham et al.
The periorbital BCC is the most common cause of orbital exenteration, especially in recurrent BCCs, infiltrative pathologic subtype, and medial canthal
In these two cases, after excision of the conjunctival tissue around the tube, we suspended it to the nasal root in the inner canthal
area by passing 4/0 silk suture around the proximal tube neck; we removed the suspension suture after 1 month.
