The Submental Artery Island Flap for Reconstruction of Acquired Maxillary and Palatal Defects After Tumor Ablation: Reversed Flow Versus the Extended Antegrade Design.

Background: The submental artery island flap (SIF) is a valid option for palatal reconstruction. However, the main limitation for its application for palatal defects is the arc of rotation. A novel modification for tunneling of the antegrade design of SIF that allows a compliant easy reach to the defect is described.

Full Bayesian analysis of double seasonal autoregressive models with real applications.

We present a full Bayesian analysis of multiplicative double seasonal autoregressive (DSAR) models in a unified way, considering identification (best subset selection), estimation, and prediction problems. We assume that the DSAR model errors are normally distributed and introduce latent variables for the model lags, and then we embed the DSAR model in a hierarchical Bayes normal mixture structure. By employing the Bernoulli prior for each latent variable and the mixture normal and inverse gamma priors for the DSAR model coefficients and variance, respectively, we derive the full conditional posterior and predictive distributions in closed form.

Aesthetic Reconstruction of Onco-surgical Mandibular Defects Using Free Fibular Flap with and without CAD/CAM Customized Osteotomy Guide: A Randomized Controlled Clinical Trial.

Background: Reconstruction of mandibular defects following ablative surgery remains a challenge even for experienced surgeons. Virtual planning and guided surgery, including computer-aided design/computer-aided manufacturing (CAD/CAM), afford optimized ways by which to plan complex surgery. This study aimed to evaluate and compare aesthetic outcome and surgical efficiency of free fibular flap (FFF) with and without CAD/CAM customized osteotomy guide (COG) for reconstruction of onco-surgical mandibular defects.

Aesthetic reconstruction of onco-surgical maxillary defects using free scapular flap with and without CAD/CAM customized osteotomy guide.

Background: Reconstruction of the maxillary defects following tumor ablation remains to be a challenge for surgeons. Virtual surgical planning (VSP), intraoperative cutting guides and stereolithographic models provides the head and neck reconstructive surgeon with powerful tools for complex reconstruction planning. Despite its use in fibular osteocutaneous reconstruction, application to the scapular free flap has not been as widely reported.

Value of diffusion MRI versus [18F]FDG PET/CT in detection of cervical nodal metastases in differentiated thyroid cancer patients.

Background: In differentiated thyroid cancer (DTC) patients, cervical nodal metastasis is a negative prognostic factor. Preoperative imaging plays an important role in treatment planning for nodal metastasis and recurrence. The aim of the study is to compare the diagnostic performance of the diffusion-weighted magnetic resonance imaging (DW-MRI) and the F-18 flurodeoxyglucose positron emission computed tomography ([18F]FDG PET/CT) in detection of cervical nodal deposits in DTC patients.

The contralateral based submental island flap for reconstruction of tongue and floor of mouth defects: Reliability and oncological outcome.

Background: Submental artery island flap (SIF) is a viable alternative to free flaps for selected oral-cavity defects, however, concerns about its oncologic safety still exists. A novel harvesting technique and its outcome is described in here.

Methods: This is a prospective study for patients with lateralized oral tongue and/or floor of mouth (FOM) cancers who undergone reconstruction using pedicled SIF based on contralateral submental vessels (CSIF) following resection.

The role of thoracodorsal artery perforator flap in oncoplastic breast surgery.

Background And Aim: Thoracodorsal artery perforator flap (TDAP) is one of the relatively new techniques in breast reconstruction. In this study, we try to evaluate the outcome of this flap in oncoplastic procedures.

Methods: This study included 40 patients of stage II breast cancer who underwent partial mastectomy with skin excision at the National Cancer Institute of Cairo University between 2011 and 2014.

Transaxillary thoracodorsal artery perforator flap: a versatile new technique for hypopharyngeal reconstruction.

Introduction:  Reconstruction of the hypopharynx and cervical esophagus after tumor resection remains a challenging problem. Different techniques of reconstruction have been described for such defects. Although free flap reconstruction, including jejunum and fasciocutaneous flaps, has gained popularity for this complex defect, regional flaps are still in use worldwide.

The submental flap for oral cavity reconstruction: extended indications and technical refinements.

Background And Purpose: The submental flap is gaining popularity as a simple technique for reconstruction of small to moderate size defects of the oral cavity. However, its role in composite defects involving the jaw is not clearly defined. Indeed, controversy exists about the flap's interference with an oncologically sound neck dissection

Patients And Methods: A total of 21 patients with oral cavity cancers over a three year period were included.

Crucial issues of hepatic artery reconstruction in living donor liver transplantation: our experience with 133 cases at Dar El-Fouad Hospital, Egypt.

Hepatic artery (HA) reconstruction is a crucial step in living donor liver transplantation (LDLT). However, many important aspects specific to this challenging step are still inadequately documented. From August 2001 through March 2007, we performed a total of 133 cases of LDLT at Dar El-Fouad Hospital.

Stepladder reconstructive options in post-ablative complex surgical defects in the head and neck.

Background: Reconstruction of head and neck defects can pose many challenges to the reconstructive head and neck surgeon. Achieving the best cosmetic and functional results without compromising the safety of oncologic surgery are the primary reconstructive goals. Speech and articulation are particularly important in oral reconstructive procedures.

The extended latissimus dorsi flap option in autologous breast reconstruction: A report of 14 cases and review of the literature.

Background: Autologous breast reconstruction using the extended latissimus dorsi flap has been infrequently reported. In the current study, the authors are reporting their own clinical experience with this method. A review of the literature is also discussed.

Maxillary swing approach for surgical resection of recurrent nasopharyngeal tumors.

Purpose : To evaluate the efficacy of salvage nasopharyngectomy for locally recurrent nasopharyngeal tumors through the maxillary swing approach. Methods : Antero -lateral access to the nasopharynx and its vicinity through the maxillary swing approach was used. Through a Weber-Fergusson-Longmire incision, the whole maxilla is freed and swung laterally while remaining attached to the masseter muscle and cheek flap.

Locally advanced tumors of the scalp: the Egyptian National Cancer Institute experience.

Background: It is well recognized that recurrent disease can occur following malignancy in the head and neck region. This is particularly true for basal cell & squamous cell carcinoma, whereby recurrence may occur many years following initial surgery or other modalities. We report here on skin malignancy occurring in the scalp with skull invasion down to the dura mater.

Fasciocutaneous free flaps for hypopharyngeal reconstruction.

Considerable controversy persists regarding the optimal technique for hypopharyngeal reconstruction. The ideal procedure should provide low mortality and morbidity, short hospitalization, a high success rate, few complications, and the greatest potential for neopharyngeal speech and deglutition. In this study, a variety of fasciocutaneous free flaps were used for reconstruction of the hypopharynx.
