Lingual Short Split: A Bilateral Sagittal Split Osteotomy Technique Modification.

The technique of sagittal split osteotomy of the mandibular ramus is an established technique that has been evolving over the years, with significant improvements regarding stability, better bone contact between the segments, and possibilities of osteosynthesis. However, paresthesia is common in the postoperatory, sometimes permanent, and undesirable fractures in the subcondylar region can occur leading to longer operative time and extraoral scars. The short lingual split technique is an easy technique that simplifies the horizontal osteotomy of the ramus and decreases the risk of undesirable fractures with a neurosensitive recovery of patients in a much shorter time because of minor trauma and nerve manipulation during the execution.

Low-level laser therapy for neurosensory recovery after sagittal ramus osteotomy.

BACKGROUND: Dento-skeletal deformities are treated combining orthodontic treatment with orthognathic surgery. One of the techniques most used in this type of surgery is the sagittal osteotomy of the mandible. This technique offers many advantages, but within its disadvantages is the inferior alveolar nerve paresthesia. There are various treatments that aim to recovery of the nerve bundle, and one of them is low intensity laser treatment. The aim of this study was to evaluate the effectiveness of low intensity laser therapy in the recovery of neurosensorial tissues after mandibular sagittal osteotomy during orthognathic surgery. METHODS: Twelve patients submitted to surgery, using mandibular sagittal osteotomy, were treated unilaterally with low intensity infrared (808 nm, GaAIAs active medium) laser, following the inferior alveolar nerve path. The other part of the mandible was treated by placebo. The parameters used were 100 mW of power, irradiancy of 3.6 W/cm2, 2.8J energy per point, an energy density of 100 J/cm2, 28 seconds at each point with a distance of 1.0 cm between points, two sessions per week with a minimum of 10 sessions, starting 48 hours after surgery. Mechanical evaluation was performed in first, fourth, seventh and tenth session. RESULTS: Significant improvement on the treated side was observed. Comparing the behavior among the variables between the treatment (T) group and the control (C) group in the General Recovery was showed a tendency to better results in the T group when compared to the C group, with statistical difference (P≤0.05) after the 10th laser therapy session. CONCLUSIONS: The treatment of neurosensorial disorders with infrared low intensity laser could be effective in accelerating recovery, providing greater comfort to the patient, and it presents advantages over other existing methods.

Labioplastia helicoidal como tratamento de lábio duplo / Elliptical excision for double lip treatment

O lábio duplo é uma anomalia caracterizada por crescimento de tecido hiperplásico acometendo na maioria das vezes o lábio superior, resultando em uma deformidade que se torna evidente quando o paciente sorri e durante a fala, ocasionando interferências na fonética e mastigação, afetando, em alguns casos, psicologicamente o paciente. Esta deformidade pode ser congênita ou adquirida, e não tem predileção por idade, raça ou gênero. O tratamento cirúrgico é indicado nos casos onde o paciente apresenta comprometimento funcional ou solicite, por motivos estéticos. Neste trabalho é descrito um caso de labio duplo adquirido onde foi feita a remoção cirúrgica através de labioplastia helicoidal, solucionando assim a deformidade estética.

The double lip is an abnormality characterized by hyperplasic tissue growth, affecting mostly the upper lip, resulting in a deformity that becomes evident when the patient smiles and during speech. It may cause interference with phonetics and mastication, in some cases affecting the patient psychologically. This deformity can be congenital or acquired and has no predilection for age, race or gender. Surgical treatment is indicated in cases where the patient is functionally compromised or requests it for aesthetic reasons. This paper describes a case of acquired double lip where surgical removal was performed by elliptical excision, thus solving the aesthetic deformity. KEY WORDS: Lip, Deformity, Maxillofacil Surgery.
