Analyses of the hyoid bone position in orthognathic surgeryVíctor Ravelo; Marcelo Parra & Sergio Olate -
The position of the hyoid bone is related to vi- tal functions. The aim of this research was to analyze the change in the position of the hyoid bone related to the surgical movement in orthognathic surgery. 52 subjects were included; the diagnosis was determined according to facial analysis, being identified as class II or class III facial deformity. The subjects were treated by maxillary and mandibular surgery without chin surgery; cone beam computed tomography were realized pre-surgical and post-surgical to perform the analyses. Statistical studies was according to the type of va- riable considering a value of p<0.05 to obtain significant differences. The results demonstrated changes in the position of the hyoid bone at different levels; in class II subjects a significant change was observed in the vertical position of the hyoid bone and there was a rise of 4.45 mm (p=0.001); in class III subjects, no significant relationships were observed in terms of horizontal or vertical position. The transverse distance showed significant changes, reducing by 3.62 mm in the post-surgical stage (p=0.008). It is possible to conclude that orthognathic surgery causes changes in the location of the hyoid bone.

Migraine surgeryClaudio Huentequeo M. Carolina Leal Alejandro Unibazo Z. Gonzalo Calbio M Juan Pablo Alister H. Sergio Olate M. -
A migraine is a primary headache, and it could be a migraine with aura or without aura, whereas it must accomplish different requests. The trigeminal-vascular system is essential in migraine physiology through bidirectional sensibilization. Migraine surgery consists of a vascular or muscular decompression of the Trigeminal nerve afferent pathways; the surgical trigger points interruption or inhibition through the neurolysis orneurectomies. Migraine surgery works on different levels, depending on the severity of the pain. Local treatments have demonstrated migraine treatment by inhibiting or decompressing muscular trigger points as the botulinum toxin infiltration. This article aims to present the case of efficacy migraine surgery treatment.
KEY WORDS: Migraine, migraine surgery, chronic migraine, myofascial pain, trigger points.

Sequelae treatment of cheilorhinoplasty using hyaluronic acidAndres Gaete Navarro Carlos Avendaño Mendoza Edgrado Pineda Taladriz -
Since the discovery of hyaluronic acid (HA) and its multiple biological functions, it has awakened interest in different areas of medicine, such as ophthalmology, rheumatology and mainly dermatology and cosmetic surgery, among other specialties, with some clinical applications. Among the non-surgical regenerative and reconstructive facial procedures, HA dermal filler is one of the most used nowadays, since it performs a supplementary task in the regeneration and healing of tissues, by providing a structure that facilitates cell growth. The cleft lip and palate (FLAP) are the most prevalent congenital craniofacial defects, where patients with FLAP may present certain lip asymmetries even after surgical treatment with multiple surgeries, which could lead the patient to various psychological disorders. The biological characteristics, the safety and the almost null adverse effects include the HA as an excellent alternative for facial filler helping the aesthetics, functionality and psychological well-being of the patient through a less invasive and non-surgical process. The aim of this article is to present a clinical case with the use of injectable HA to correct the volumetric and aesthetic lip asymmetries produced in the post-surgical rehabilitation of patients with fissures and discusses its use.
KEY WORDS: Hyaluronic acid, dermal filler, cleft lip, cleft palate, facial aesthetics.

The hygyene and quaility of sleepIvan González Díaz -
ABSTRACT: Sleep hygiene is the set of environmental recommendations aimed at promoting healthy sleep, such as diet, exercising regularly, eliminating noise from the environment and maintaining a regular schedule. Quality sleep characterized by being comfortable and sufficient helps alleviate daily physical and mental fatigue and restore metabolic functions. The correct quality of sleep requires changes in posture throughout the night. The main function of the pillow is to support the cervical spine in a neutral position, in addition to avoiding the accumulation of physical fatigue during sleep, it assists in movements, re- duces noise and vibrations, in addition to relieving pressure on the head. When an adequate sleep cycle is suppressed, symptoms such as the presence of daytime fatigue, psychomotor impairment, accidents, deterioration of physical and psychological health appear. Poor quality sleep is prevalent in 3-16% of the general population. Characterized by symptoms of awakening, such as neck pain, stiffness, headache, shoulder and arm pain. Poor quality of sleep cau- ses increased sensitivity to pain, while the presence of pain during the day will be followed by a poor-quality night. People with poor quality of sleep are more susceptible to temporomandibular joint dysfunction. Approximately 33% of the population is affected by temporomandibular joint dysfunction, of which up to 70% refers poor quality sleep. The aim of this research is to know some variables included in hygiene and quality to sleep.
KEY WORDS: Sleep quality, temporomandibular joint dysfunction.

Rotational flap of the sternocleidomastoid muscle as an alternative in mandibular reconstructionIvan González Díaz Arturo de Jesús Chávez Caballero -
El músculo esternocleidomastoideo se localiza en la región late- ral del cuello. Su irrigación procede de las arterias occipital, tiroidea superior, carótida externa y supraescapular. Su inervación lo da el nervio accesorio que puede o no penetrar el músculo. El colgajo rotacional de esternocleidomastoideo fue descrito por Jianu en 1909, para manejo de parálisis facial. Utilizado por Owens desde 1955 para cubrir defectos del tercio inferior de la cara. La mandíbula es una estructura esencial del esqueleto facial y la mejor opción para su reconstrucción es la utilización de colgajos libres microvascularizados, sin embargo, ciertas condiciones pueden inhabilitar dicha opción (condición sistémica o vascular, radiación). La utilización del colgajo rotacional de esternocleidomastoideo en conjunto con la hemimandibulectomía trae consigo la ventaja funcional y estética. Permite obtener simetría, inclusive rehabilitación protésica debido al proceso de fibrosis que sufre el músculo. La reconstrucción ideal debe de sustituir todos los planos, lo cual no siempre es posible, por lo cual se deben de determinar diferentes alternativas que sean menos invasivas, como el presente ejemplo del colgajo rotacional de esternocleidomastoideo que es de gran ayuda para lograr simetría y evitar la exposición del material de osteosíntesis. El colgajo rotacional del músculo esternocleidomastoideo es una alternativa importante para mejorar el resultado estético y funcional del paciente que conlleva algún tipo de resección mandibular.
PALABRAS CLAVE: Colgajo rotacional, músculo esternocleidomastoideo, colgajo libre microvascularizado

Le Fort I osteotomy to treat recurrent pleomorphic adenoma and facial deformityLuciano H. F. Lima Eder A. Sigua-Rodriguez Douglas R. Goulart Sergio Olate Márcio de Moraes -
Pleomorphic adenoma is a benign lesion of the salivary glands. The most common intraoral site is the palate, with tendency to affect females between the fourth and seventh decades of life. The most reported treatment for this lesion is the surgical removal. Therefore, the aim of this report was to present the case of a 31-year-old female patient who presented a recurrence of pleomorphic adenoma and facial deformity. Recurrence was observed 22 year after first surgical treatment. Tumor involved the palatal area, nasal floor and maxillary sinus; the patient showed an augmented vertical growth of the maxilla and mandibular retrognathia with a previous compensatory orthodontic treatment. The treatment included Le Fort I osteotomy for enucleation of the tumor, upper reposition of the maxilla and a chin osteotomy for advancement. 5 year follow-up show a stable result with no recurrence. Diagnosis and treatment strategies are discussed. We concluded that this treatment is stable; Le Fort I osteotomy can help to treat the tumor and facial deformity at the same time.

Temporomandibular joint replacement. Criteria for indication and follow-upSergio Olate Víctor Ravelo Claudio Huentequeo Alejandro Unibazo -
The temporomandibular joint (TMJ) is a complex structure in the craniomaxillomandibular area. Its pathological conditions show deficiencies at different levels, leading to the replacement in some cases. The objective of this article is to analyze the current indication, criteria and follow-up conditions of these patients. A narrative review was carried out, identifying the main indications for the use of TMJ prostheses and the evaluation of different criteria currently reported in the international literature; the versatility of using standard prostheses and custom prostheses is also discussed. It is concluded that the replacement of the TMJ show indications and relevant criteria that must be evaluated; getting the most beneficial treatment for our patient should be a primary criterion in controversial indications.

Is there any complication in guided implant dentistry: A systematic reviewMahsa Aeinehvnad Shaqayeq Ramezanzade Sanaz Mirzahoseini Paymon Mehryar Parisa Yousefi Seied Omid Keyhan Hamid Reza Fallahi -
The aim is to assess the clinical studies regarding the reported complications of implant placement with computer-guided surgery in partially/ fully edentulous patients. The PubMed and Google Scholar databases were searched from 2000 to 2020 for pertinent clinical studies written in English. The PRISMA 2020 guidelines were followed. Two examiners conducted the quality assessment according to the methodological quality and synthesis of case series and case reports. At first, a total of 1057 papers were screened and 17 papers finally were included of which, one was the cohort, three were case series and 13 were case reports. Complications and errors of surgical guides were mostly three parts: 6 out of 17 articles reported preoperative complications, 9 articles reported complications during surgery that occurred for the patient or surgeon, and 11 articles reported postoperative complications. Computer-guided implantology is not flawless. So dentists should receive comprehensive training to prevent serious complications. Sufficient mastery to create a correct and accurate position for the implant and observing the important points of anatomical structures such as the alveolar nerve is one of the important points of this technique.
