Aesthetic surgery for microtia

We describe here a technique for reconstruction of the external ear based upon an autogenous costal cartilage graft which is inserted into a cutaneous pocket dissected in the auricular area. Three subsequent procedures are then performed: rotation of the ear-lobe; reconstruction of the tragus; and elevation of the auricle. The ideal age for reconstruction is about 7 years. This technique was originally described by Brent, who has a very extensive experience with this kind of surgery. Skin deficiencies can be overcome by using either a temporo-parietal fascial flap or a skin expander.     

Free vascularized fascia lata flap for total columella reconstruction

IntroductionDespite their relatively small size, columellar defects, including both external and internal elements, are exceedingly difficult to reconstruct. Local, regional, and distant flaps have been described for reconstruction. Herein, we present a novel technique for reconstruction of the columella using vascularized free fascia lata from the anterolateral thigh with structural replacement and skin grafting.MethodsThis novel technique utilizes a small anterolateral thigh flap, formed into vascularized fascia lata without the overlying subcutaneous fat or skin. The fascia lata is inset into the columellar and caudal septal defect after a cartilage framework is constructed and is microsurgically anastomosed to either distal facial or angular vessels. A skin graft from the ALT donor site is then secured over the fascia.ResultsThis technique has been applied successfully in patients with either isolated columella or in multi-subunit reconstruction following total rhinectomy with no flap or reconstructive failures. Given the low morbidity of flap harvest and minimal access incisions, this has been reliably accomplished with short (1–2 day) hospital stays.ConclusionRapid and aesthetically acceptable reconstruction of total nasal columella defects in isolation or with additional nasal subunit reconstruction, is possible utilizing this novel technique. Here we discuss pearls and pitfalls of its use following surgical resection of malignancy.     

Sandwich technique for sigmoid sinus wall reconstruction for treatment of pulsatile tinnitus caused by sigmoid sinus diverticulum/dehiscence

Abstract

Background: If the pulsatile tinnitus caused by sigmoid sinus diverticulum/dehiscence cannot be diagnosed and treated, it can lead to significant morbidity and mortality.

Aim: To assess the sandwich surgical technique for sigmoid sinus wall reconstruction for the treatment of pulsatile tinnitus caused by sigmoid sinus diverticulum/dehiscence.

Methods: A chart review was conducted with 17 patients suffering from pulsatile tinnitus caused by sigmoid sinus diverticulum/dehiscence who underwent sinus wall reconstruction surgery between January 2014 and July 2019.

Results: Of the total patients studied, 16 were female, and one was male. The procedure was performed on the right ear of 15 patients and on the left ear of 2 patients. The pulsatile tinnitus disappeared in all patients following the sinus wall reconstruction surgery using the sandwich technique. The mean follow-up time was 25?months (a range of 8-55?months). In the follow-up period, no recurrence of pulsatile tinnitus was found. None of the patients experienced major complications such as thrombosis.

Conclusions: The sandwich surgical technique for sinus wall reconstruction as a treatment for pulsatile tinnitus caused by sigmoid sinus diverticulum is safe and effective.     

Mandibular reconstruction in 2004: an analysis of different techniques

PURPOSE OF REVIEW: The field of mandibular reconstruction has evolved dramatically over the past fifty years. Numerous advances in microsurgical technique, plating technology and instrumentation, and an understanding of donor site angiosomes have made consistent and reliable mandibular reconstruction possible. Refinements in technique continue to improve the functional and aesthetic outcomes of oromandibular reconstruction. This review discusses the current state-of-the-art techniques for mandibular reconstruction and highlights the latest innovations in technique. RECENT FINDINGS: The most common indication for oromandibular reconstruction remains ablative surgery for advanced neoplastic processes of the oral cavity and oropharynx. Reconstruction of these complex three-dimensional composite bony and soft-tissue defects is paramount for rehabilitation of form and function. Vascularized osseous free tissue transfer is the state-of-the-art for mandibular reconstruction. The long-term excellent functional and aesthetic outcomes of this technique have recently been reported. The most commonly used free flaps for mandibular reconstruction are the fibula, iliac crest, and scapula. Each of these typically accepts endosseous implants improving functional outcomes. The use of mandibular reconstruction plates and coverage with a soft-tissue flap remains a reconstructive option for selected patients. The latest refinements in technique include temporary intraoperative external fixation, the use of periosteal free flaps, distraction osteogenesis, and development of biodegradable biopolymer scaffolds for mandibular defects. SUMMARY: Oromandibular reconstruction, although a challenge for the head and neck reconstructive surgeon, is now reliable and highly successful with excellent long-term functional and aesthetic outcomes.     

Biphasic ceramics and fibrin sealant for bone reconstruction in ear surgery

Bone reconstruction is still a matter of concern in middle ear surgery despite the large number of surgical techniques proposed. A composite made of biphasic calcium phosphate ceramic granules mixed with human fibrin sealant, forming a moldable material that is easy to set for bone reconstruction, has been used with success over a 16-year period for reconstruction of the posterior canal wall or for mastoid obliteration. In a retrospective series of 72 ears with long-term follow-up (average follow-up of 46 months), regular microscopic examination, and computed tomographic controls, we have evaluated this bone reconstruction technique for radical mastoidectomy cavities or the closed technique. The bone reconstruction material provided an immediate anatomic reconstruction that remains stable and is well tolerated over the long term. A slight leakage of granules in the meatus was initially observed in several patients with transient aseptic otorrhea. Fifty-seven ears were followed up for 1 year or more. Satisfactory clinical results with complete regression of the mucous membrane disease were found in 82.4% of the patients, with perfect stability of the material in 65%. We did not observe any cases of recurrent cholesteatoma in or behind the filling material. Eighteen biopsies were performed between 8 and 84 months after surgery during a second surgical step performed for functional purposes or for recurrent cholesteatoma; 17 of the 18 cases showed osteointegration of the filling material. After a 16-year experiment, we consider this technique to be a highly satisfactory procedure that could be extended to other situations of bone reconstruction.     

How we do it: Free conchal cartilage revisited for primary reconstruction of attic defects in combined approach tympanoplasty

• ? There are concerns over the efficacy of free cartilage autografts in attic reconstruction (scutumplasty) for combined approach tympanoplasty (CAT).
• ? Our operative technique uses free conchal cartilage autografts and an additional piece of conchal cartilage to buttress the reconstruction.
• ? Of the 16 cases where this technique was used, there were two cases (13%) of failure of the attic reconstruction and a keratin pearl (residual disease) in one case (6%). This compares favourably with comparable series using a variety of reconstruction techniques.

     

Eine Möglichkeit der Pharynxrekonstruktion mit Stimmrehabilitation nach Laryngopharyngektomie

Summary In cases of large pharyngeal carcinomas resection of most of the upper digestive tract of this region is necessary.For one-stage reconstruction we use the island flap technique. The myocutaneous island flap of the pectoralis major muscle allows a variety of reconstructive possibilities by using it.For this purpose and for functional reasons we have to maintain the nerve bundles which innervate the myocutaneous island flap. Electromyographics shows the importance of this postulation.In addition to the concept of one-staged reconstruction it is essential that our technique allows surgical speech rehabilitation, tongue motility and good swallowing.     

"Double barrel" free fibula flap and vascular risk. A national investigation in France

Introduction

The free fibula flap is the most commonly used flap for mandibular reconstruction thanks to its multiple advantages. Its main drawback is the thin width of the bone section. The “double barrel” fibula flap is a solution to this problem allowing reconstruction of both basilar and alveolar ridges for a stable prosthetic dental rehabilitation. The authors wanted to assess its use, in France, to evaluate its reliability, and to determine its indications.

Patients and methods

The authors sent a questionnaire to the 25 French Maxillo-Facial University Hospital Departments. Questions concerned the surgical technique, its indications, and the operative results, between January 2002 and December 2007.

Results

Out of the 18 teams who answered, 16 used a free fibula flap for mandibular reconstruction but only seven used the double barrel technique, for a total of 24 double barrel reconstructions. Only one total necrosis was reported. The indications for double barrel fibula flap were nearly all for corpus reconstruction and the operating overtime was less than one hour.

Discussion

The international literature review analysis gives results which compare to French ones, with a weak rate of necrosis despite the intermediate rectangular ostectomy. This technique may be recommended especially since it does not increase the operative time much and it improves dental restoration.     

Reconstruction of complex peripheral facial nerve defects by a combined approach using facial nerve interpositional graft and hypoglossal-facial jump nerve suture

Objectives/Hypothesis:

To describe a modified facial nerve reconstruction technique for complex defects of the facial fan after parotid surgery that avoids synkinesis between upper and lower face.

Study Design:

Retrospective case series.

Methods:

Patients who had undergone radical parotidectomy with a large defect of the facial fan, reconstruction of the upper face by facial nerve interpositional graft, and reconstruction of the lower face by hypoglossal‐facial nerve jump nerve suture were included in this series.

Results:

Four patients underwent the modified combined approach after tumor resection and prior to postoperative radiotherapy in three of the four cases. Surgery was combined with an upper lid weight implantation. Regeneration of the face was successful in all cases within 12 to 16 months. Most important, the separated reanimation of the upper and lower face circumvented synkinesis of the upper and lower face. This factor was essential for good functional results. Using the hypoglossal jump technique instead of a classical cross‐nerve suture technique prevented the sacrifice of ipsilateral tongue function.

Conclusions:

The presented method offers satisfactory results for facial reanimation and avoids synkinesis between the upper and lower face. Using the jump technique instead of a classic hypoglossal transfer as it was described originally for the combined approach avoids long‐term sequelae for the tongue.

Double-barrel fibular free flap for mandibular reconstruction: beneficial alternative for dental implanted rehabilitation (5 cases)

INTRODUCTION: As major loss of mandibular bone stock requires a vascularized transfer, fibula free flap reconstruction is considered to be the best free flap for its length and reliability. Its main advantage is to accept dental implants. Single or double-barrel reconstruction can be performed. Double-barrel reconstruction is generally preferred because the bone superposition offers enough height to allow dental implants. MATERIAL AND METHODS: We reviewed five selected cases of double-barrel fibula free flap adaptive mandibular reconstruction performed among a series of 11 oral rehabilitations with planned dental implants, focusing on the technical aspects. RESULTS: Today, dental rehabilitation has been achieved in three double-barrel fibula flaps. Details are reported concerning the implant step. DISCUSSION: In this perspective, we discuss the choice of the reconstructive technique in order to obtain adequate bone height. Early in our experience and for different reasons discussed in the text, we used a single barrel fibula flap. This technique provided sufficient height in some cases, but had to be completed by bone grafts in few patients. Our experience illustrates the usefulness of the double barrel technique which provide definitive bone height sufficient for dental implants. The double-barreled technique should be considered as the best solution.     

Posthemicricoidectomy reconstruction with a composite hyoid-sternohyoid osseomuscular flap: the Rethi–Ward technique

Our objective was to introduce a new technique for cricoid cartilage reconstruction. A 74-year-old male patient with a history of a 6-month progressively worsening dyspnea was found to have an extensive mass of the left cricoid cartilage. Although the extent of his disease would necessitate total laryngectomy, the patient underwent an open extended left hemicricoidectomy with reconstruction of the defect by a pedicled osseomuscular flap composed of the body of the hyoid bone and the contralateral sternohyoid muscle. Both frozen section and subsequent histopathological evaluation gave the diagnosis of a chondrosarcoma. A Montgomery T-tube was left in place for 3 months and was subsequently replaced by a tracheostomy tube to be removed 1 month later. Six months postoperatively, the patient remains in an excellent respiratory condition. The reconstructed site is patent without any signs of restenosis as up to date. We conclude that our technique appears to be a reliable alternative to total laryngectomy in cases of extended chondrosarcomas, as well as in cases where reconstruction of the cricoid cartilage is mandated. Further follow-up and additional cases are warranted. Presented at the 6th Congress of the European Laryngological Society, 31 August–2 September 2006, Nottingham, UK.     

3D CT Imaging Method for Measuring Temporal Bone Aeration

Objective --3D volume reconstruction of CT images can be used to measure temporal bone aeration. This study evaluates the technique with respect to reproducibility and acquisition parameters. Material and methods --Helical CT images acquired from patients with radiographically normal temporal bones using standard clinical protocols were retrospectively analyzed. 3D image reconstruction was performed to measure the volume of air within the temporal bone. The appropriate threshold values for air were determined from reconstruction of a phantom with a known air volume imaged using the same clinical protocols. The appropriate air threshold values were applied to the clinical material. Results --Air volume was measured according to an acquisition algorithm. The average volume in the temporal bone CT group was 5.56 ml, compared to 5.19 ml in the head CT group ( p = 0.59). The correlation coefficient between examiners was > 0.92. There was a wide range of aeration volumes among individual ears (0.76-18.84 ml); however, paired temporal bones differed by an average of just 1.11 ml. Conclusions --The method of volume measurement from 3D reconstruction reported here is widely available, easy to perform and produces consistent results among examiners. Application of the technique to archival CT data is possible using corrections for air segmentation thresholds according to acquisition parameters.     

The sandwich cartilage shoe technique for ossicular reconstruction in a case of an unsecure stapes footplate

This article describes a new surgical method for total ossicular reconstruction in a case of a broken stapes footplate. We developed the technique of the "cartilage shoe sandwich," which consists of two surgical steps. First, the closure of the oval window is achieved by a cartilage shoe without a central perforation. During this surgical intervention, the prearrangement of a secure placement of a total ossicular replacement prosthesis is provided by a second cartilage with a central hole that is plugged with silicone. In a staged procedure, the silicone plug is removed and the ossicular reconstruction can be performed. The audiological results of the first patients show a stable inner ear function with an air-conduction gain of 9 dB. The technique described herein has proven to be safe and reliable in total ossicular reconstruction in the event of an unsecure stapes footplate.     

Paradigm change in the treatment of non-melanoma skin cancer of the auricle: reconstruction with full thickness skin grafting instead of wedge excision

Non-melanoma skin cancer (NMSC) has become an epidemic disease and is predominantly located in the head and neck area. While historically auricular NMSCs are treated by means of a wedge excision, we describe a more elegant technique with excellent esthetical results. We conducted a retrospective cohort study of 43 consecutive patients with NMSC of the auricle who underwent reconstruction with a full thickness skin graft (FTSG). All grafts survived. Two patients (5 %) showed crust formation, but fully recovered. One patient had an irradical resection for which he required a limited re-excision. All patients showed excellent esthetical results. When treating NMSC of the auricle, reconstruction with a FTSG demonstrates several important advantages. It is a relatively simple but oncological safe technique; it leads to excellent esthetical and functional outcomes, and shows high patient and surgeon satisfaction.     

Use of a temporoparietal fascial flap in difficult reconstructions of the external ear

Temporo parietal fascial flap is a way of total ear reconstruction when there is not a sufficient quantity of available skin in auricular region. This flap very thin, supplied by superficial temporal vessels is located above the auricle and can cover the framework's convolutions. This technique has been well described by Burt Brent. Our experience is based upon 12 total ear reconstruction with this kind of flap. When there is an extreme skin shortage, but of good quality, we discuss the technique of skin expander.     

Delayed pharyngoesophageal reconstruction with combined local and regional flaps: a case report

We describe an unusual technique for performing delayed pharyngoesophageal reconstruction following circumferential pharyngolaryngectomy. The patient was a 52-year-old man who underwent a circumferential pharyngolaryngectomy for the treatment of hypopharyngeal carcinoma. In view of the patient's poor clinical status, we opted to perform a pharyngostomy and an esophagostomy and to postpone pharyngoesophageal reconstruction for a more appropriate occasion. After the patient's clinical condition had sufficiently improved, the repair was planned. Microsurgical flaps were contraindicated because the blood flow through the cervical vessels was unreliable. Pharyngoesophageal continuity was restored with a cervical flap vascularized by the prevertebral fascia, a pectoralis major myocutaneous flap, and a deltopectoralis flap. A reasonable degree of deglutition was achieved, and no signs of stricture were detected. Although our technique was unusual, we believed that it might provide a valid alternative when a delayed pharyngoesophageal reconstruction is required and free flaps are contraindicated for any reason.     

Temporary removal of the posterior bony canal wall with reconstruction using microplate osteosynthesis in cholesteatoma surgery: a case series and description of the technique

We describe the surgical technique of temporary removal of the posterior auditory canal wall with reconstruction and report the outcome of using this technique as a treatment method for cholesteatoma in a case series. In 32 cases of cholesteatoma surgery a technique of temporary removal of the posterior bony wall was applied. During primary surgery the posterior auditory canal wall was removed using an oscillating saw. For the purpose of reconstruction, the canal wall was repositioned and fixed using two titanium microplates (n = 26). In case the canal wall could not be reconstructed with osteosynthesis, either glass-ionomeric cement (BioCem?) was used for fixation (n = 4) or fibrin glue (Tissucol?) (n = 2) to support the posterior wall. The outcome includes the healing process in the first postoperative month, the absence of residual or recurrent disease and the successful reconstruction of the posterior auditory canal wall as evaluated during second-look surgery. When microplates where used, we saw healing problems of the canal skin in about 4 % of patients. Recurrent cholesteatoma was found in 4 cases (14 %), residual cholesteatoma in 8 ears (25 %). In the osteosynthesis group, successful reconstruction was achieved in 25 patients (96 %). In 3 out of 4 patients of the glass-ionomeric cement group (75 %) excessive granulation tissue developed with extensive bony lysis. Temporary removal of the posterior auditory canal wall offers potential for the control of cholesteatoma. Our first results suggest that osteosynthesis allows for a good anatomical and functional reconstruction.     

Ossicular reconstruction: Incus versus universal titanium prosthesis

Objectives

The main purpose of this study is to compare audiological outcomes of incus reconstruction, Xomed Medtronic universal titanium partial ossicular replacement prosthesis (PORP) and total ossicular replacement prosthesis (TORP). We also compared results based on surgical technique, history of previous surgery, form of the prosthesis head, pathology and frequency.

Methods

A chart review was performed and included reconstructions performed between June 2003 and December 2006. Results were based on air–bone gap and pure tone average.

Results

Postoperative mean air–bone gap and mean pure tone average are significantly lower using incus reconstruction compared with the titanium prosthesis groups. PORP and TORP groups yielded similar outcomes. Closure of ABG is similar in all three groups. Postoperative results were better using an intact canal wall mastoidectomy compared with a canal wall down technique, but ABG closure was similar in both groups. Primary surgeries gave better results than revisions of reconstructions performed by the senior author or elsewhere.

Conclusion

Though Xomed Medtronic titanium prostheses are effective in ossicular reconstruction, incus reconstruction is at least as effective when feasible. Canal wall down mastoidectomy should be reserved for cases where preservation of the canal wall is contraindicated. Previous same ear surgery is a poor prognostic factor for successful outcome. Preliminary results indicate that round head PORPs may be superior to their oval head counterparts.     

Airway salvation after failed anterior graft in a child with long segment stenosis

Objectives

1-Recognize difficulties and review techniques in long-segment laryngotracheal stenosis repair. 2-Contribute to increasing clinical and surgical skills in pediatric airway reconstruction through reporting our experience with a novel reconstruction technique involving use of a failed anterior graft and prolonged postoperative stenting.

Methods

Case report: 10 year old male with history of burn injury who required a tracheostomy due to prolonged intubation/inhalational injury in 2005. Subglottic/tracheal stenosis was identified and he subsequently underwent anterior costal cartilage grafting involving the thyroid cartilage, cricoid cartilage, and trachea. He remained tracheostomy dependent for six years due to failed graft and postoperative complications despite several attempts to improve the airway with CO2 laser and balloon dilation. In 2011, preoperative CT with 3D reconstruction revealed a 32 mm long segment of complete stenosis. The patient underwent suprahyoid release and single stage reconstruction with cricotracheal resection and partial preservation of the anterior costal cartilage graft found in the luminal scar tissue.

Results

Postoperatively the patient was stented with a nasal endotracheal tube for 2 weeks. Bronchoscopy showed mild tracheal collapse inferior to the site of anastamosis and granulation tissue at the site of anastomosis. Granulation tissue was removed and the subglottic anastomosis site was stented with a 2 cm Dumon stent for 6 months.

Conclusion

The problem of long segment stenosis after failed cartilage graft reconstruction of the airway is evaluated and a novel technique of laryngotracheal reconstruction involving a pre-existing failed anterior graft and short segment stenting is described.
