[Palpebral marginoplasty in the management of distichiasis: About 104 eyes]. / La marginoplastie palpébrale dans la prise en charge du distichiasis : à propos de 104 yeux.

Distichiasis is an anomaly of the of the eyelid margin characterized by the presence of a second row of eyelashes arising from the posterior lamella. It is a rare condition whose severity is related to corneal complications. There are two forms: congenital and acquired, the latter of which is the most frequent in our population, resulting mainly from chronic inflammation. There are several treatment modalities, the choice of which is up to the practitioner depending on the means at his or her disposal and the risk-benefit ratio. We report a series of 104 eyes (90 patients) undergoing surgery for distichiasis using the marginoplasty technique with labial mucosal autograft, collected between January 2000 and September 2021. The main indication was any distichiasis with more than seven lashes per eyelid. The mean age of the patients was 65.5 years. With a mean follow-up of over 24 months, a reduction in functional signs was noted in over 95% of cases. The success rate after marginoplasty with labial mucosal autograft alone was 82.7%. The recurrence rate was 17.3%, which patients underwent additional treatment by argon laser photoablation with very good final results (96% final success rate). Marginoplasty with labial mucosal autograft represents a technique of choice in distichiasis threatening the cornea, particularly in cases of distichiasis with a significant number of eyelashes to be treated.

[Argon laser trichiasis treatment: Technique, indications and results (report of 230 cases)]. / Traitement des cils trichiasiques au laser argon : technique, indications et résultats (à propos de 230 cas).

Trichiasis is a common misdirection of the eyelashes, creating a sharp point responsible for decreased vision, blepharospasm and corneal irritation. It may cause neurotrophic corneal disease leading to blindness. The etiology of trichiasis remains largely undetermined in our patient base. Treatment is based on pragmatic methods that take into account the ciliary ecosystem and the static and dynamic examination of the eyelids. For this, several therapeutic modalities exist: mechanical epilation, cryotherapy, surgery and electrolysis. Each of these techniques has its indications, advantages, and complications. Destruction of the lash follicles with argon laser has many advantages: it is an outpatient procedure, rapid, reproducible, well tolerated, and above all, effective in the long term. The aim of our study is to examine the advantages, technique, indications and results of argon laser trichiasis treatment. This was a retrospective study including 201 patients (230 eyelids) treated in our ophthalmology department over a period of 9years (from January 2011 to March 2020), all of whom were seen for various lash-related symptoms and treated with argon laser electrolysis. Results were considered satisfactory when no lash regrowth occurred within six months of the last laser session. Eighty-two percent of our patients (n=188) showed a good therapeutic response after the first session, 9% (n=21) needed an additional session, and only 6% of the patients (n=14) required a 3rd and/or 4th session, without resorting to surgery. The indications for this treatment should be limited to trichiasis of fewer than or equal to 7 per eyelid, without associated lid malposition (entropion), the treatment of which should be surgical and entirely different. Treatment of trichiasis with argon laser can be an alternative or complement to surgery. Results are excellent but require rigorous adherence to the technique and indications.

Class I malocclusion with severe bimaxillary protrusion: a successful result.

This case report describes the successful treatment of a 29-year-old young woman who had severe bimaxillary dento-alveolar protrusion, with the four premolars already extracted. Her face was convex, with a closed naso-labial angle, protruding and everted lower lip, associated with mentalis strain and a class I canine and molar relationships. After retraction of anterior teeth by using maximum anchorage mechanics through directional forces, facial changes were impressive, with a significant improvement of the dento-alveolar protrusion. Retraction of the incisors had corrected proquelia, reduced lips eversion and had improved the chin projection. As the lips were retracted, mentalis strain was reduced; this improved chin projection.

[Orthodontic treatment and gingival hyperplasia: a case report]. / Traitement orthodontique et hyperplasie gingivale. A propos d'un cas.

Gingival hyperplasia is a relatively frequent pathologic condition during orthodontic treatment. Oral hygiene can be easily altered in such cases because of additive and irritative effects of orthodontics appliances. So, adequate control of the gingival inflammation is required. The present case reports on a 13-year-old boy who developed, during orthodontic treatment, a gingival hypertrophy that was successfully treated with periodontal surgery consisting on an apically positioned flap procedure. For this purpose, multidisciplinary approach involving orthodontist and periodontist was crucial in the perspective of optimal clinical issues.
