Split cricoídeo posterior endoscópico con injerto de cartílago costal / Endoscopic posterior cricoid split with costal cartilage graft

RESUMEN A pesar de los avances en cirugía de vía aérea, tanto abierta como endoscópica, la inmovilidad bilateral de cuerdas vocales continúa representando un desafio significativo para los cirujanos de vía aérea. Entre las alternativas quirúrgicas existen tanto abordajes endoscópicos como transcervicales, no obstante, la mayoría de estas técnicas modifican estructuralmente regiones de la cuerda vocal y/o aritenoides de manera permanente. La traqueostomía ha sido el tratamiento de elección en niños con inmovilidad bilateral de cuerdas vocales severamente sintomática, sin embargo, el procedimiento ideal debiese establecer una vía aérea adecuada evitando la necesidad de realizar una traqueostomía, y a la vez no generar un deterioro de la función fonatoria. La capacidad de expandir el aspecto glótico posterior sin modificación estructural de aritenoides y/o ligamento vocal ha convertido a la sección cricoidea posterior endoscópica con injerto de cartílago costal en una alternativa quirúrgica atractiva para estos casos. En este trabajo se realiza una revisión de la literatura y presenta un caso tratado mediante esta técnica en el Hospital Guillermo Grant Benavente de Concepción, Chile.

ABSTRACT Despite advances in both open and endoscopic airway surgery, bilateral vocal cord immobility still poses a significant challenge for airway surgeons. Among the surgical alternatives there are both endoscopic and transcervical approaches. However, most of these techniques structurally modify certain regions of the vocal cord and/or arytenoids permanently. Tracheostomy has been the treatment of choice in severely symptomatic children with bilateral immobility of vocal cords. Nevertheless, the ideal procedure should establish an adequate airway, avoiding the need to perform a tracheostomy, and at the same time not causing a deterioration of the phonatory function. The ability to expand the posterior glottis without structural modification of the arytenoids and/or vocal ligament has converted the posterior endoscopic cricoid split with costal cartilage graft into an attractive surgical alternative for these cases. In this article we review the literature and present a case treated by this technique in the Guillermo Grant Benavente Hospital in Concepción, Chile.

Correction of secondary unilateral cleft-lip nasal deformity using autologous costal cartilage grafts / 中华医学美学美容杂志

Objective To explore the comprehensive approach and efficacy of secondary unilateral cleft rhinoplasty by using autologous costal cartilage grafts.Methods Secondary rhinoplasty was performed in 28 patients with unilateral cleft-lip nasal deformity.The costal cartilage was harvested through a mini-invasive incision.Septal deviation was corrected,and nasal tip framework was reconstructed with the autologous costal cartilage through direct transcolumellar incision.Diced cartilage fragments were used to augment the depressed alar base.Nasolabial muscles were repositioned to restore the balance of muscular tension system.Results The appearance of the nasal deformity was greatly improved in all the 28 cases postoperatively by follow-up from 3 to 12 months.Increased stability and symmetry of the nasal tip,along with the improvement of nasal breathing function was achieved and sustained effectively.Conclusions Definitive secondary unilateral cleft rhinoplasty using autologous costal cartilage grafts provides good aesthetic and functional results.

Augmentation rhinoplasty with rib cartilage graft

@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To investigate the outcome and complications of augmentation rhinoplasty with rib cartilage grafts.<br /><strong>METHODS:</strong><br /><strong>Design:</strong> Retrospective study<br /><strong>Setting:</strong> Tertiary Government Hospital<br /><strong>Subjects:</strong> Patients who underwent dorsal nasal augmentation with autologous rib cartilage grafts between June 2008 and October 2012.<br /><strong>RESULTS:</strong> A total of 12 patients (3 male, 9 female) were included in the study. Mean age was 29 years. Seven were cases of primary simple rhinoplasty with four cases of revision (previously using alloplastic materials) and one case of trauma. Indications for the procedure were all cosmetic. There was no incidence of infection, both in the donor and recipient sites, warping of the graft, graft extrusion, resorption, pneumothorax, chest wall deformity or prolonged edema. Post-operative pain in the donor site was relieved by oral pain medications. No revision surgery was required.<br /><strong>CONCLUSION:</strong> Costal cartilage is a good option for structural support of the nose. In our experience patients have become wary of the complication of allografts and have opted to use autografts. The surgeon's knowledge of the nasal anatomy as well as his or her experience with autologous grafts plays a major role in avoiding post-operative morbidity.</p>

Using Rib Bone Turnover Technique, Prevention of Chest Wall Depression after Microtia Reconstruction

PURPOSE: Reconstruction of microtia using costal cartilage graft is commonly used technique nowadays. The chest wall depression at the donor site after the graft, however, has been noticed in many articles. Prevention or correction technique for the depression at the donor site also has been reported and we also have been concerned about the problem. This article is a case report about a new technique preventing chest wall depression after costal cartilage graft. METHODS: We selected total 15microtia patients who visited our clinic, from December 2005 to July 2007. They were 10 male and 5 female patients and the mean age was 11.9 years. The average follow up period was 9.2months(2 to 15months). We used 6, 7, and 8th costal cartilage for microtia reconstruction. And then we turned over pivot of cartilage resection margin, after bihalving costal cartilage involving about 5-6cm of 6th and 7th rib bone. After microtia reconstruction, chest donor sites were evaluated by physical examination and radiography. RESULTS: Postoperative depression at the donor site was much less when the costal cartilage turnover technique was performed. Postoperative physical examination and three dimensional reconstruction CT showed that the rest part of rib bone was turned over and it supported the soft tissue defect during respiration. CONCLUSION: We expect that the turnover rib bone will not be absorbed after graft, as well as offering mechanical support, compared to the other reports.
