Evaluation of life quality, self-confidence and sexual functions in patients with total and partial laryngectomy
Objective: In this study patients who have undergone partial (PL) or total laryngectomy (TL) were evaluated for life quality, self-esteem and sexual dysfunctions
The multiple osteotomized free iliac osteocutaneous flap for reconstructions of complex maxillofacial and oromandibular defects
The vascularized iliac osteocutaneous flap has been used successfully for jaw reconstruction. To obtain a better contour of the reconstructed area in large upper and lower jaw resections, the transferred bone actually needs to be osteotomized. Single closing-wedge osteotomy of the iliac flap for mandibular reconstruction has been previously described. In this article, the modified multiple osteotomized perforator-based versatile free iliac osteocutaneous flap is described. Eleven cases were enrolled. Seven patients had wide anterior mandibular resections due to oral cavity and mandibular tumors; 3 patients had a defect due to explosive injury and 1 patient had complicated orbitomaxillary defect due to blast injury. Skin paddle was based on the perforators. In 8 patients, the bony segment was divided into 3 segments by 2 osteotomies, whereas in 2 patients the bony segment was divided into 4 segments by 3 osteotomies. In 10 cases, the flap was used for anterior mandibular defects, whereas in 1 case the flap was customized to fit an L-shaped defect at the naso-orbito-maxillary region. The overall flap success rate was 100%. No resorption or morbidity related to the osteotomy of the bony segments was observed. The size of perforator skin paddle was 6 to 8 x 15 to 18 cm. Physical and radiologic examinations showed proper bone healing without any additional complications. The modified multiple osteotomized free osteocutaneous iliac flap can provide a safe and versatile bony segment to be arranged and adapted to reconstruct complex mandibular and maxillofacial defects

Minimally invasive injection laryngoplasty in the management of unilateral vocal cord paralysis after video-assisted mediastinal lymph adenectomy
Introduction: Video-assisted mediastinal lymphadenectomy (VAMLA) is a valuable tool for invasive staging of the mediastinum. Unilateral vocal cord paralysis (UVCP) may occur in patients following VAMLA and may result in secretion retention within the lungs, atelectasis and associated infectious situations such as pneumonia. Minimally invasive injection laryngoplasty (ILP) is the treatment of choice in UVCP
Connecticut (CCCRC) Olfactory Test: Normative Values in 426 Healthy Volunteers.
Application of Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory test to healthy Turkish volunteers, obtain normative data set and analyse the role of age, sex and smoking on olfactory scores. The present study was conducted at Bezmialem Vakif University, Department of Otorhinolaryngology. Total of 426 healthy volunteers were subjected to CCCRC olfactory test which consists of n-butanol smell threshold test and smell identification test. Olfactory function score was assessed (0: worst score; 7: best score) and mean scores were calculated. Mean age was (36.7 ± 11.1; range, 17–68). 46.2 % of the subjects were male and 53.8 % were female; 37.1 % were smokers and 62.9 % were non-smokers. Mean n-butanol threshold score was 6.36 out of 7, mean identification score was 6.34 and mean total score was 6.35. According to CCCRC score: there were no anosmic individuals, 0.5 % were severely hyposmic, 2.6 % were moderately hyposmic,15.3 % were mildly hyposmic and 81.6 % were normosmic. CCCRC olfactory test is cost-effective, simple and practical. It can be easily applied in clinical settings. The CCCRC olfactory test is appropriate for assessment of olfactory function: Turkish population is familiar in terms of the odors used in CCCRC test. The power of this study is that it provides a normative data set against which many factors can be compared
Cellular Angiofibroma of the Nasopharynx
Angiofibroma is a common tumor of the nasopharynx region but cellular type is extremely rare in head and neck. A 13-year-old boy presented with frequent epistaxis and nasal obstruction persisting for 6 months. According to the clinical symptoms and imaging studies juvenile angiofibroma was suspected. Following angiographic embolization total excision of the lesion by midfacial degloving approach was performed. Histological examination revealed that the tumor consisted of staghorn blood vessels and irregular fibrous stroma. Stellate fibroblasts with small pyknotic to large vesicular nuclei were seen in a highly cellular stroma. These findings identified cellular angiofibroma mimicking juvenile angiofibroma. This article is about a very rare patient of cellular angiofibroma of nasopharynx
Decellularization of Trachea With Combined Techniques for Tissue-Engineered Trachea Transplantation
Objectives The purpose of this study is to shorten the decellularization time of trachea by using combination of physical, chemical, and enzymatic techniques. Methods Approximately 3.5-cm-long tracheal segments from 42 New Zealand rabbits (3.5±0.5 kg) were separated into seven groups according to decellularization protocols. After decellularization, cellular regions, matrix and strength and endurance of the scaffold were followed up. Results DNA content in all groups was measured under 50 ng/mg and there was no significant difference for the glycosaminoglycan content between group 3 (lyophilization+deoxycholic acid+de-oxyribonuclease method) and control group (P=0.46). None of the decellularized groups was different than the normal trachea in tensile stress values (P>0.05). Glucose consumption and lactic acid levels measured from supernatants of all decellularized groups were close to group with cells only (76 mg/dL and 53 mg/L). Conclusion Using combination methods may reduce exposure to chemicals, prevent the excessive influence of the matrix, and shorten the decellularization time
In Vivo Tissue-Engineered Allogenic Trachea Transplantation in Rabbits: A Preliminary Report
Conventional tracheal reconstruction techniques are not successful at restoring functional units in situations with extensive damage involving more than half the length of the trachea. For the first time, we investigated in vivo tissue-engineered trachea regeneration from a decellularized cadaveric trachea matrix with seeded adult adipose tissue-derived mesenchymal stem cells (MSCs) and investigated the integration of the matrix into the recipient tracheal side. For the procedure, 1.8-cm grafts were prepared from 3.5-cm tracheas of three donor rabbits. Then, tracheal grafts were rendered nonimmunogenic using a decellularization technique. MSCs isolated from recipient rabbit adipose tissue were cultured and marked before being seeded in the decellularized matrix. A total of 1.8 cm of the recipient tracheas was replaced with either a decellularized tracheal matrix (group 1) or tracheal matrix-seeded MSCs (group 2). Rabbits survived 17 +/- 2 days in the first group, and the causes of death were separation in the anastomosis region, airway obstruction, and infection. In the second group, animals were sacrificed on the 30th, 60th, and 90th days of follow-up. Histopathological analysis revealed the integration of MSCs seeded-decellularized cadaveric tracheas to the recipient tracheal sides and increased angiogenesis. The MSCs were traced by fluorescence microscopy in the ciliated epithelium, under the epithelium, and in the cartilage of the integrated new trachea. Tracheas generated by autologous cells and tissue-engineering techniques will be a great source for the treatment of life-threatening tracheal injuries after the completion of related studies
