Quantifying upper lip height difference between two young male and female populations by direct surface measurement: Implications for gender-affirming upper lip shortening surgery.

The female upper lip is shorter than its male counterpart. We have recently described a precise direct surface measurement technique of the philtral height. In this study we aim to quantify the difference in philtral height using this same measuring technique between two groups of young male and female Lebanese subjects. The mean philtral height obtained in the young male group was 15.7 ± 1.7 mm. By comparing this result to the previously described mean philtral height of 14.3 ± 1.9 mm in the young female group, we obtained a mean difference of 1.3 ± 1.8 mm between the two groups. This result confirms and quantifies by direct surface measurement the gender difference in upper lip height and should be considered when planning a gender-affirming upper lip shortening surgery.

Botulinum toxin for benign essential blepharospasm: A systematic review and an algorithmic approach.

BACKGROUND: Currently, there is no standardised approach for benign essential blepharospasm treatment with botulinum toxin, and controversies still exist regarding this subject. OBJECTIVE: The objective of this systematic review is to summarise and compare all the published data regarding benign essential blepharospasm treatment with botulinum toxin. METHODS: On October 3, 2018, an online search of the Medline database was conducted. All articles with a detailed description of their botulinum toxin injection technique for benign essential blepharospasm were included in this review. RESULTS: Five studies were selected for inclusion with a total of 854 patients. Four of the included studies used onabotulinumtoxin A and one study used abobotulinumtoxin A. All studies injected the pretarsal orbicularis occuli muscle. The preseptal orbicularis occuli was injected in four studies, and the preorbital muscle in three studies. The most commonly used method of evaluation was the Jankovic Rating Scale. Adverse events were transient, and dose related. Ptosis was more frequently encountered with the preseptal orbicularis injections. CONCLUSION: Botulinum toxin injection for benign essential blepharospasm is a non-invasive and safe procedure. The pretarsal muscle should be considered as the key component when treating benign essential blepharospasm with botulinum toxin. We developed an algorithmic approach to the treatment of benign essential blepharospasm with botulinum toxin. However, further randomised controlled trials are warranted.

Treating facial nerve palsy by true termino-lateral hypoglossal-facial nerve anastomosis.

Hypoglossal-facial nerve anastomosis is a time-proven technique for the repair of facial nerve palsy. Efforts have been made to reduce hypoglossal nerve injury, the main drawback of the technique. In this study, the anastomosis is a true termino-lateral neurorrhaphy with only an epineural window in the hypoglossal nerve sheath. A re-routing technique of the temporal facial nerve is also performed to allow a direct anastomosis to the hypoglossal nerve without the need for a jump graft. The first three results reported are very encouraging, with a satisfactory return of facial mimics and without any impairment of lingual function.

Thumb reconstruction for aesthetic reasons using an exteriorised microvascular pedicle.

Thumb reconstruction following amputation is usually performed in order to restore function. Nevertheless, the reconstruction should be cosmetically acceptable in order to be fully functional, and, in some cases, reconstructive surgery may be justified for purely aesthetic reasons. The most satisfying aesthetic results in adults are obtained with microsurgical partial great-toe transfer. The technique that we use for thumb reconstruction is illustrated by two case reports: that of a 26-year-old female patient and that of a 35-year-old male patient. Both patients had a distal thumb amputation with destroyed nail apparatus, and both sought thumb reconstruction for cosmetic reasons. Aesthetic reconstruction was performed in both cases with a partial ipsilateral great-toe transfer, composed of nail apparatus, underlying bone and custom-made pulp tissue. The vascular anastomosis was done at the snuff-box, through a small incision, with an exteriorised pedicle. The result was satisfactory in both cases, with minimal donor-site sequelae. Partial toe transfer has proven to be a reliable technique for thumb reconstruction. It is an evolving technique. Many modifications have been introduced to optimise the aesthetic result and to reduce donor-site morbidity. Our technique allows us to restore thumb length, replace the missing nail and reconstruct the pulp, with acceptable sequelae at the donor toe. The exteriorised-pedicle technique prevents pedicle compression and twisting and reduces scarring and stiffness. It does, however, require delicate postoperative care and a second procedure for pedicle division.

Melanotic neuroectodermal tumour of infancy involving the orbit and maxilla: surgical management and follow-up strategy.

Melanotic neuroectodermal tumour (MNET) of infancy is a rare benign but locally aggressive tumour. We describe our surgical treatment of MNET of the orbital region. There was osteogenic relapse involving the bone of the orbit, 20 days after macroscopically complete excision of the primary tumour when the patient was 12 weeks old. This is only the second report of osteogenic relapse in MNET. The relapse was treated by excision of the involved orbital floor, preserving the orbital periosteum. The tumour has not recurred in 23 months of follow-up. Residual tumour islets may regress spontaneously after incomplete excision of MNET, but the relapse rate is between 15% and 45%. In our opinion, excising a safety margin of a few mm of apparently healthy bone reduces the risk of relapse. In contrast, the orbital contents should be preserved if they are macroscopically normal. Follow-up consisted of frequent physical examinations and CT scans.

[Renovascular arterial hypertension in the framework of von Recklinghausen's neurofibromatosis. Apropos of a case]. / Hypertension artérielle rénovasculaire dans le cadre de la neurofibromatose de Von Recklinghausen. A propos d'un cas.

Arterial hypertension in patients with neurofibromatosis is most often due to an associated pheochromocytoma. In rare cases the etiology of arterial hypertension is renovascular. Surgical treatment is mandatory when the stenosis is located in the proximal segment of the vessel. Angioplasty is hazardous in this setting due to the fibrotic nature of the culprit lesion. The authors report a case of ostial narrowing of the right renal artery in a 16-year-old girl with severe arterial hypertension and neurofibromatosis. The operation consisted of resection of the culprit lesion and reimplantation of the renal artery on the aorta. Postoperatively her blood pressure returned to normal.
