Outcomes and Utility of Intracranial Free Tissue Transfer.

Complications associated with intracranial vault compromise can be neurologically and systemically devastating. Primary and secondary repair of these deficits require an air and watertight barrier between the intracranial and extracranial environments. This study evaluated the outcomes and utility of using intracranial free tissue transfer as both primary and salvage surgical repair of reconstruction. A retrospective review was performed of all subjects who underwent intracranial free tissue transfer as primary or salvage repair. A total of 13 intracranial free tissue transfers were performed on 11 subjects: osteocutaneous radial forearm free flaps (n = 6), partial myofascial rectus abdominis flaps (n = 5), temporoparietal fascia flap (n = 1), and serratus anterior myofascial flap (n = 1). Primary reconstruction was performed on 4 subjects with the remaining being salvage repair. Indications for surgery included neoplasm (n = 6 of 11), ballistic trauma (n = 3 of 11), motor vehicle accident (n = 1 of 11), and infection (n = 1 of 11). Three subjects required additional surgical repair for CSF leak and pneumocephalus, with 2 subjects requiring an additional free tissue transfer at a different site. In our experience, free tissue transfer is an effective primary and salvage surgical technique in the reconstruction of complex intracranial problems.

Implications of Free Temporoparietal Fascial Flap Reconstruction in the Pediatric Population.

The temporoparietal fascial flap (TPFF) is a versatile tool that can be used in the reconstruction of head and neck and distal upper and lower extremity defects. The TPFF may be harvested as a pedicle or free flap as well as with the temporalis muscle and/or adjacent calvarial bone as a composite flap. As a free flap, the TPFF has been used as a joint gliding surface with coverage of nerves and tendons, for extremity soft tissue repair, for tracheal and pharyngeal coverage and for defects of the nose, scalp, and auricle. This article focuses on the use of the free TPFF in the pediatric population through systemic review of the medical literature. Current perspectives on the use of this flap and microsurgery in general in pediatric patients are addressed.

Comparative Evaluation of Reconstructive Methods in Oral Submucous Fibrosis.

Oral submucous fibrosis is a chronic, progressive, scarring, precancerous condition of oral mucosa which on progression causes severe trismus. To compare and evaluate the efficiency of buccal fat pad, platysmal mucocutaneous flap, nasolabial flap, collagen membrane graft, split thickness skin graft and temporoparietal fascia in reconstruction of surgical defect created by excision of fibrous bands in oral submucous fibrosis. After 6months of follow-up, the interincisal mouth opening was 40.0mm in case of buccal pad fat, 24.5mm in temporoparietal fascia flap group, 33.8 in collagen membrane graft group, 34.5mm in platysma flap group, 34.7mm in nasolabial flap group, 29.3mm in split thickness skin graft. ANOVA statistical analysis for postoperative interincisal distance at various time intervals and between pre-, intra- and postoperative interincisal distances were carried out which showed the results were significant at p value < 0.05 in all groups. No postoperative complications were noted in buccal fat pad group, split thickness skin graft group and collagen membrane group. However, platysmal group had flap necrosis and temporoparietal flap group patients had to undergo a second debulking procedure after one month. From our study, we concluded buccal fat pad yields superior results with respect to postoperative mouth opening and related complications.

What is the best method for prevention of postparotidectomy Frey syndrome? Network meta-analysis.

Prevention of Frey syndrome (FS) after parotidectomy using an interposition barrier has long been gaining a wide popularity; however, there is no clear evidence regarding which preventive technique is more effective. The aim of this network meta-analysis (NMA) is to answer the question: What is the best method for prevention of FS after parotidectomy? A comprehensive search of the PubMed, Embase, SCOPUS, and Cochrane library was conducted to identify the eligible studies. The outcome was the incidence of subjective Frey syndrome (SFS) and objective Frey syndrome (OFS). The Bayesian NMA accompanied with a random effects model and 95% credible intervals (CrIs) were calculated using GeMTC R package. Thirty-four studies (n = 2987 patients) with five interventions, namely Alloderm (ADM), temporoparietal fascia (TPF), sternocleidomastoid muscle (SCM), superficial musculoaponeurotic system (SMAS), and free fat graft (FFG), were compared together and with no interposition barrier (NB). The results of NMA showed a statistically significant reduction in both SFS and OFS when ADM, TPF, SMAS, FFG, and SCM were compared with NB. No statistical differences were observed when comparing ADM, SCM, SMAS, FFG, and TPF. TPF ranked the best of all treatments (59.4%) and was associated with the least incidence of SFS; whereas ADM ranked the best of all treatments (61.1%) and was associated with the least incidence of OFS. All interventions (TPF flap, ADM, FFG, SMAS, and SCM) were associated with a significant reduction in the incidence of FS when compared with NB. TPF and ADM showed the best outcome with the least incidence of SFS and OFS, respectively.

Role of the temporoparietal fascia free flap in salvage total laryngectomy.

The procedure for salvage total laryngectomy (STL) is burdened by a high rate of postoperative complications as a result of delayed wound healing in previously irradiated tissue. Several observational studies have investigated the role of prophylactic vascularized flaps to aid pharyngeal closure after STL and prevent the development of PCF. The use of a temporoparietal fascia free flap (TFFF) as an overlay flap for STL has been described previously in two published studies and both sets of authors agreed that the most obvious benefit of the TFFF in STL is a reduced PCF rate with low site morbidity and good functional outcomes. The aim of this video is to illustrate the use of the temporoparietal fascia flap to provide an adjunctive reinforcement layer in the reconstruction of the pharynx.

A Dynamic Costal Cartilage Platform Promotes Ocular Prosthetic Excursion: Preliminary Report.

Background:The quality of life of the face involves mainly its configuration, and it plays an important functional role in communication skills. Thus, having artificial eyes is extremely essential in maintaining the quality of life of patients who have lost their eyeballs. We will present the details of the technique, including tips and innovations for eye socket reconstruction using spherical costal cartilage implant, which leads to dynamic and aesthetic results.Methods:There were 19 cases of eye socket reconstruction using costal cartilages from 2008 to 2020. The patient age range was 18–77 years old. There were 10 cases of anophthalmia and 9 cases of ocular phthisis. In our operative method, we created the costal cartilage implant by harvesting the sixth costal cartilage of the affected side. If extraocular muscle remained, we sutured each muscle to the cartilage.Results:Our method made application of thin artificial eyes possible in all cases. Regarding postoperative complications, there were 1 case of postoperative infection and 1 case of vascular failure of temporoparietal fascial flap. Seventeen cases were wet socket, and 2 cases were dry socket. We had attained movement of the artificial eye in 15 cases.Conclusions:Eye socket reconstruction is considered one of the most challenging operations, and various postoperative complications appear in the long term. Costal cartilages are considered as the most suitable materials to create the base of artificial eyes.

Novel Surgical Treatment of Recurrent CSF Leak by Temporoparietal Temporalis Myofascial Flap: A Series of 6 Cases

With the advent of modern endoscopes and a better anatomic understanding of the skull base, the indications of endonasal approaches are increasing. These procedures may be complicated by high rates of postoperative cerebrospinal fluid (CSF) leak, and reconstruction of the defect remains challenging. In the anterior skull base, vascularized grafts have been reported as superior in preventing CSF leakage and infection. The Hadad-Bassagasteguy flap, being a pedicled flap, is our first line flap to reconstruct the skull base. When we were not successful with this flap, we resorted to different flaps. We modified the originally described temporoparietal fascial flap by Fortes etal and applied clinically. The objective of this paper is to briefly describe the modification of the flap and to review the clinical outcome. From 2014 to 2018, in 6 cases of CSF leak with the appropriate indication, we used the temporoparietal myofascial flap repair that is a modification of the temporoparietal fascial flap by Fortes etal. We took all the 6 patients in our study and followed them up. All of the 6 repairs were successful, and no CSF leak was found just after the operation in 6- to 48-month follow-up. We recommend our modified novel temporoparietal myofascial flap as a very good option in case of failed cases of postoperative CSF leak.

Retrospective analysis of free temporoparietal fascial flap for defect reconstruction of the hand and the distal upper extremity

IntroductionSoft tissue reconstruction of the hand and distal upper extremity is challenging to preserve the function of the hand as good as possible. Therefore, a thin flap has been shown to be useful. In this retrospective study, we aimed to show the use of the free temporoparietal fascial flap in soft tissue reconstruction of the hand and distal upper extremity.MethodsWe analysed the outcome of free temporoparietal fascial flaps that were used between the years 2007and 2016 at our institution. Major and minor complications, defect location and donor site morbidity were the main fields of interest.Results14 patients received a free temporoparietal fascial flap for soft tissue reconstruction of the distal upper extremity. Minor complications were noted in three patients and major complications in two patients. Total flap necrosis occurred in one patient.ConclusionThe free temporoparietal fascial flap is a useful tool in reconstructive surgery of the hand and the distal upper extremity with a low donor site morbidity and moderate rates of major and minor complications.

Vascular pedicled flaps for skull base defect reconstruction.

ObjectiveTechniques for reconstruction of skull base defects have advanced greatly since the introduction of the vascular pedicled nasoseptal flap in 2006. The objective of this review is to assess the current state of the field by examining both intranasal and extranasal techniques of vascular pedicled skull base defect repair, their indications and success rates, and novel techniques that are currently under investigation.MethodsA review of the literature describing the use of vascular pedicled flaps in skull base defect reconstruction was conducted using PubMed and Google Scholar.ResultsThe nasoseptal flap remains the most widely used vascular pedicled flap for endoscopic repair of skull base defects. Its ease of harvest, wide arch of rotation, and high success rates make it a popular choice among surgeons. Several variations including a “rescue” nasopseptal flap have been developed. Other less commonly used pedicled intranasal flaps include the middle turbinate flap and the posterior pedicled inferior turbinate flap. Additionally, several novel vascular pedicled flaps have been developed and tested in small cohorts of patients. Extranasal flaps such as the pericranial flap and the temporoparietal fascia flap are used less frequently than intranasal flaps. However, they remain valuable options for reconstruction in certain situations.ConclusionAdvancements continue to be made in the field of skull base defect reconstruction using vascular pedicled flaps. Though the nasoseptal flap remains the most widely utilized option, additional intranasal techniques continue to be developed and tested to optimize surgical outcomes and patient care.Level of EvidenceNA

Tips and tricks of temporo-parietal fascial flap in post burn ear reconstruction

ObjectivesTemporoparietal fascial flap (TPFF) is one of the most versatile flaps for facial reconstruction. TPFF can be used as a locoregional flap for various indications to provide effective and robust cover. In this article we shall discuss the tips and tricks of TPFF which we have used extensively for post burn ear reconstruction in our clinical experience of more than 20 years with consistent results. MethodsThis is a retrospective review of 497 cases of post burn ear reconstruction using pedicled Temporoparietal fascial flap done at Department of Plastic and Reconstructive Surgery, Lok Nayak Hospital, which is tertiary care Government hospital in New Delhi from March 2000 to March 2020. We started use of this flap initially for ear reconstruction (microtia) cases and slowly expanded our indications over the period of time to post burn ear reconstruction apart from others due to its high vascularity and versatile nature. ResultsWe have used pedicled Temporoparietal fascial flap to our advantage with varied indications and excellent results. We had minor complications which were easily managed with 11 cases of partial flap loss and one case of total flap loss. We shall discuss all the details in our review. ConclusionWe wish to conclude that pedicled Temporoparietal fascial flap (TPF) is an excellent versatile flap which can be easily molded over irregular contours and yields good long-standing results with low complication rates.

Novel Classification of Posttraumatic Ear Deformities and its Surgical Management.

Background Classification of posttraumatic ear deformities and its reconstruction is an uphill task for a reconstructive surgeon as they present in various combinations. In our study, we have described ear deformity as per a new classification and reconstructed the ear accordingly. Method Posttraumatic ear deformity was described under the following four headings: (a) zone of defect, (b) size of defect, (c) missing components, and (d) condition of surrounding skin. Twenty-six posttraumatic ear deformities were operated using postauricular skin flap (14), temporoparietal fascial (TPF) flaps (8), preauricular skin flap (1), intralesional excision (2), and primary closure with chondrocutaneous advancement in one patient. Costal cartilage was used for reconstruction of framework wherever required. Framework elevation was done 4 to 6 months postoperatively. Results Posttraumatic ear deformity was more common in males. Bite injury and road traffic accidents were the common causes. Zones I, II and III were most frequently involved. Four patients complained about size, contour, and projection of reconstructed ear. Three patients were not satisfied by the appearance of junction between reconstructed and residual ear. Four patients in whom the reconstruction was done with TPF, costal cartilage, and thin (SSG) split skin grafts complained of hyperpigmentation of reconstructed ear. Conclusion Classification of posttraumatic ear deformity and its reconstruction is a surgical challenge. Unscarred postauricular skin and TPF flaps are the workhorse flaps for reconstruction of acquired ear deformities. Our classification helps in describing the defect, documenting it, planning reconstruction, and aiding in assessing postoperative outcomes.

Quantitative determination of the optimal temporoparietal fascia flap necessary to repair skull-base defects.

The ability to reconstruct large cranial base defects has greatly improved with the development of pedicled vascularized flaps. The temporoparietal fascia flap (TPFF) is a viable alternative to the Hadad-Bassagasteguy nasoseptal flap for large ventral skull-base defects. This study aims to characterize the size of the TPFF necessary for optimal ventral skull-base reconstruction. Eleven formaldehyde-fixed cadaveric heads were used to harvest TPFF of varying heights on each side (total = 22). TPFF was passed through the pterygomaxillary fissure (PMF) to the ventral skull base to assess its coverage. For a subgroup of 12 sides, the TPFF was trimmed to determine the minimum height necessary for coverage. The TPFF height was (mean ± standard deviation [SD]) 14.72 ± 1.02 cm (range, 12.5 to 16.5 cm) and width was 8.43 ± 1.05 cm (range, 6 to 10.5 cm). The distance from the TPFF pedicle through the PMF was 5.8 ± 0.5 cm (range, 5 to 6.5 cm). All TPFF flaps provided complete ipsilateral coverage of clival defects, and all but 1 covered the entire clivus. All TPFF flaps, when rotated anteriorly, provided coverage up to the cribriform plate. The minimum TPFF height necessary for complete coverage of cribriform defects and ventral defects up to the planum sphenoidale was 12 cm. TPFF height for specimens with and without complete ventral skull-base coverage was significantly different (p < 0.0001). The TPFF is a versatile alternative to the nasoseptal flap and a height of at least 12 cm can provide enough coverage for all ventral skull base defects.

Secondary Salvage of the Unsatisfactory Microtia Reconstruction.

Because auricular reconstruction is a complex and relatively uncommon procedure, there are many patients that have had disappointing reconstructions. This study describes the authors' large experience with secondary procedures in patients with unsatisfactory or failed initial ear reconstruction. A prospectively maintained database of all consecutive patients who underwent secondary total ear reconstruction from March of 1991 to December of 2017 was reviewed. Demographic data and outcomes were assessed. Patients with acquired absence of the ear were not included. There were 144 microtia patients that met the inclusion criteria. Patient age at the time of the secondary reconstruction ranged from 3 to 59 years. Follow-up duration ranged from 1 to 21 years. Primary reconstruction was performed with rib cartilage in 91 patients, porous polyethylene implant in 47 patients, prosthesis in four patients, and irradiated cadaver rib cartilage in two patients. All secondary reconstructions were performed with porous polyethylene implants. The alloplastic framework was covered with a temporoparietal fascia flap in 76 patients, an occipital fascia flap in 64 patients, and a free fascia flap in four patients (two radial forearm flaps in the same patient, one contralateral temporoparietal fascia flap, and one lateral arm flap). Fourteen patients (10 percent) had complications requiring revision surgery. Secondary surgery was successful in all but one patient. These data represent the largest series of secondary total ear reconstructions. The use of a porous polyethylene implant is an ideal method for these patients because of its minimal morbidity and relatively low complication rate. Therapeutic, IV.

The History of Alloplastic Ear Reconstruction for Microtia.

Microtia reconstruction is a unique and challenging field in reconstructive surgery. In the early 20th century, many different alloplastic materials have been used in an attempt to recreate the fibrocartilaginous framework of the native ear. These materials include celluloid, tantalum wire cage, nylon mesh, polyethylene, and acrylic. The first standard for alloplastic microtia reconstruction, silicone, is one fraught with complications and failures. This alloplastic material is walled off by the host and prone to scar tissue formation and extrusion. Alloplastic microtia reconstruction largely shifts to porous polyethylene, where the results are markedly superior. This is attributed to the porous structure of porous polyethylene, which allows tissue ingrowth. Moreover, the use of the temporoparietal fascia flap for total coverage of the implant has impressively lowered the risk of implant extrusion. However, there is paucity in the literature regarding the evolution of alloplastic microtia reconstruction, especially characterizing historical mistakes, significant technique evolutions, and drawbacks/advantages of materials. This review serves as a guide both to avoid repeating mistakes and to improve outcomes.

Morbidity in Patients With Separation of Cartilaginous Framework: Temporoparietal Fascia Flap and Treatment With Dermal Regeneration Template.

The full creation of an ear requires 2 reconstruction stages. In the second stage of reconstruction, the cartilaginous framework placed at first stage is separated from the head creating an auriculocephalic sulcus. Then a piece of rib cartilage is placed in the sulcus to maintain this separation and is covered with tissue that allows the integration of a full-thickness skin graft. A descriptive study based on the pre and postoperative medical records and photographic archives of patients diagnosed with microtia who underwent separation of the cartilaginous framework from February 2010 to July 2015 in the Plastic and Reconstructive Surgery Department at Hospital General Dr. Manuel Gea González. Fifty-four patients met the selection criteria. The temporoparietal fascial flap was performed on 85% (n = 46), and 8 cases with random occipito-temporal fascial flap in association to a dermal regeneration template. The average time at the operating room was 177 minutes in patients with temporoparietal fascial flap versus 84.5 minutes in dermal regeneration template. The complication rate was 25.9% (n = 14), being similar rate with both techniques. Coverage with dermal regeneration template and random occipito-temporal fascia flap as an alternative use instead of temporoparietal fascial flaps, offers good postoperative results, lower operating times, and similar rate of complications, with the advantage of producing no visible scars and reserve the temporoparietal fascial flap for possible exposure of the cartilaginous framework.

PERFORMANCE STATUS AND QUALITY OF LIFE AFTER RECONSTRUCTIONS OF BUCCAL MUCOSAL AND RETROMOLAR TRIGONE DEFECTS BY SKIN AND FASCIAL FLAPS IN ONCOLOGYCAL PATIENTS

The aim: of the study is to compare surgical and functional results as well as quality of life after use of skin flaps - platysma myocutaneus flap, supraclavicular artery flap and fascial flaps - temporoparietal fascial flap, buccal fat pad for plastic closure of the buccal and retromolar trigone mucous surgical defects in cancer patients. Material and methods: A retrospective comparative analysis of the results of surgical treatment of buccal and retromolar trigone mucosal cancer in 56 patients operated from 2009 to 2014 was made. The patients were divided into two groups: the first included 26 patients, with reconstruction of fascial flaps, the second group included 30 patients, with reconstruction of postoperative defects with skin flaps. Surgical results: the average duration of surgery, the average duration of inpatient treatment and the presence of complications were compared in the both groups. Functional results in both groups were compared in 6 and 12 months after surgery with the Performance Status Scale for Head and Neck Cancer Patients (PSS-HN), and quality of life was assessed by the University of Washington Quality of Life questionnaire, version 4. Results: Average duration of surgery, average time of inpatient treatment, and postoperative complications did not differ significantly in both groups (P> 0.05). Data of performance status and quality of life in patients with reconstruction of mucosal defects and retromolar trigone with skin flaps were significantly better (P> 0.05) in 6 and 12 months after surgery, compared with the group of patients who underwent defect reconstruction with fascial flaps. Conclusions: The method of choice in reconstruction of medium and large defects of the buccal and the retromolar trigone mucous is usage of skin flaps: the platysma myocutaneus flap and the flap of the supraclavicular artery.

Single stage cochlear implantation in radical mastoid cavity- a surgical dilemma

Objective: To describe the potential problems of cochlear implantation in mastoid cavity with possibilities of extrusion of electrode array by breakdown of epithelial lining or flap cover recurrent cholesteatoma and spread of infection to the implant. The issues with surgical management and subsequent follow up is discussed. Methods: In a Series of 170 Cochlear Implantations at our centre, four patients had Cochlear Implantation with Blind sac closure, complete removal of epithelium from the radical mastoid cavity, obliteration of the cavity with temporoparietal fascia flap and electrode insertion. Follow up ranging from 21 months up to 84 months is available. One patient during follow up had to undergo re implantation due to extrusion of the electrodes. Results: All the patients had good outcome regarding hearing improvement. One of the patients had to undergo exploration and re implantation of electrodes due to extrusion of electrodes through the external auditory canal. This patient had a canal cholesteatoma. Discussion: An important issue in single stage procedure is ensuring complete removal of fibro epithelial lining of the cavity. The advantage is cost reduction and minimizes the need for multiple general anesthesia. A follow up CT scan at regular intervals is required to detect recurrence. Conclusions: The patients undergoing cochlear implantation in a radical mastoid cavity require intensive follow up with computerized tomography to detect recidivism, Single stage cochlear implantation in radical mastoid cavity is an appropriate therapeutic decision by the cochlear implant surgeon.

Cochlear implant surgery: Analysis of changes in surgical strategies for better outcomes

Objectives: Like any surgical procedure, the cochlear implant surgery is constantly in evolution. This paper highlights the various modifications in the surgical strategies that have been incorporated into the surgical procedure with regard to the changes in incision, the route of insertion of electrodes, the depth of electrode insertion, and ultimate outcome in the patients. The modifications in the surgical strategy have been based on scientific evidence. Methods: A retrospective analysis of 220 cochlear implant procedures done with the posterior tympanotomy approach has been performed. The cases performed with the alternate technique, and cochlear anomalies have been excluded. The various surgical strategies which wer evaluated included the incision, the periosteal flap, the drill hole technique, the route and depth of insertion and the surgical outcome. Results: The incorporation of mini incision drastically reduced the incidence of postoperative infection and exposure of implants (P < 0.05). The authors classified the round window membrane at posterior tympanotomy and graded them accordingly. The depth of insertion of electrodes was also evaluated prospectively. The use of modified tie down technique reduced the operative time. The vascularized temporoparietal fascia flap helped in saving 5/9 implants with exposure. Conclusions: The cochlear implant surgery is constantly evolving. This paper highlights the critical appraisal of different steps in surgical strategies that have been incorporated into the surgical procedure. This reflects the surgical audit of our cases. These surgical strategies have resulted in reducing the incidence of complications in our series and improving outcomes.
