P G Giacomini, S Mocella, S Di Girolamo, R De Berardinis, A Boccieri
Nasal tip under projection is often found in rhinoplasty cases both for congenital or post-traumatic deformity. Nasal trauma may result in alteration of the external and internal nasal structures with following aesthetic impairment and difficulties in breathing. Post-traumatic surgery is frequent, but restoration of pre-traumatic form and function remains a challenge. The present paper describes a new method to increase tip projection by a columellar strut harvested from the autologous nasal bone and cartilage of the resected hump...

AIM: Identify injury-related, patient-reported and treatment-related prognostic factors for 5-year outcomes in acutely ACL-ruptured individuals managed with early reconstruction plus exercise therapy, exercise therapy plus delayed reconstruction or exercise therapy alone. METHODS: Exploratory analysis of the Knee Anterior Cruciate Ligament, Nonsurgical versus Surgical Treatment (KANON) trial (ISRCTN84752559). Relationships between prognostic factors (baseline cartilage, meniscus and osteochondral damage, baseline extension deficit, baseline patient-reported outcomes, number of rehabilitation visits, graft/contralateral ACL rupture, non-ACL surgery and ACL treatment strategy) and 5-year Knee Injury and Osteoarthritis Outcome Score (KOOS) pain, symptoms, sport/recreation and quality of life (QOL) scores were explored using multivariable linear regression...

OBJECTIVES: There are not many chances to arthroscopically reassess how graft tunnel malpositions in primary anterior cruciate ligament reconstruction (ACLR) associate with intra-articular degeneration in revision ACLR. This study was aimed to evaluate whether radiographic tunnel position in primary ACLR affect cartilaginous changes and bucket-handle meniscus tears in revision ACLR. METHODS: Thirty-five patients who underwent revision ACLR were recruited; their primary surgeries were single-bundle reconstructions...

BACKGROUND: Distal scaphoid excision is one treatment option for osteoarthritis of the scaphotrapeziotrapezoid (STT) joint following failure of conservative measures. Potential complications of this procedure include injury to the carpal ligaments, cartilage, and radial artery. METHODS: A single case was identified by the senior author, and the medical record was reviewed for surgical notes, progress notes, and radiographs. RESULTS: A 68-year-old male sustained ruptures of the flexor digitorum superficialis (FDS) and flexor digitorum profundus to the index finger 3 years following a distal scaphoid excision for symptomatic STT osteoarthritis...

PURPOSE OF REVIEW: To review the recent literature in regards to complications after reconstruction of Mohs defects, outline common pitfalls and to discuss the literature on avoiding complications as outlined per aesthetic subunit. RECENT FINDINGS: Complications in facial Mohs reconstruction commonly consist of infection, wound necrosis and dehiscence, hematoma and suboptimal scarring. However, site-specific complications such as hairline or eyebrow distortion, eyelid retraction or ectropion, nasal contour abnormality, alar retraction, nasal valve compromise, significant facial asymmetry or even oral incompetence must also be considered...

INTRODUCTION: Giant cell tumor (GCT) or osteoclastoma is an osteolytic, mostly benign but locally aggressive tumor occurring in young adults at the epiphysis. Area of predilection is mainly long bones (85-90%). 4% of GCT are also found in iliac bone, spine and only 2% in hand (of which GCT phalanges are more common than metacarpal). GCT of metatarsal is a very rare occurrence with very few cases being reported so far. We report a case of GCT 1(st) metatarsal in a 40-year-old male which is a very rare entity...

BACKGROUND: The eyelid structure can be divided into an inner layer and an outer layer. Reconstruction of a full-thickness eyelid defect is accomplished by full-thickness composite tissue transfer or combined layered reconstruction. We present a new technique for inner layer reconstruction using ear cartilage and oral mucosa. METHODS: The oral mucosa graft is harvested from the inner side of the lower lip to fit the defect size and shape. The ear cartilage graft is harvested as a rectangular strip...

Gemma C Wilson, Laura Dias, Callum Faris
Importance: Warping of costal cartilage is well described; however, its strength and abundance still make it a desirable graft material, especially in complex reconstructive rhinoplasty. Despite multiple methods of cartilage harvest, carving, and preimplantation treatment being developed over the years, warp remains a challenging clinical problem. Objective: To assess whether the 30° oblique split method of preparing costal cartilage grafts produces less warping of the graft than the current standard of harvesting the central segment of a rib using the concentric carving method...

Cartilage tissue engineering is making progress but the competing available strategies still leave room for improvement and consensual overviews regarding the best combinations of scaffolds and cell sources are limited by the capacity to compare them directly. In addition, because most strategies involve autologous cell transfer, once these will be optimized, the resulting implants require individual quality control prior to grafting in order to emphasize patient-to-patient differential responsiveness to engineering processes...

OBJECTIVES/HYPOTHESIS: The most promising stem cell-derived tracheal transplantation approach is dependent upon the use of decellularized tracheal grafts. It has been assumed that a sterilization step, such as gamma radiation, would damage the delicate extracellular matrix of the graft, thus rendering it less viable for cellular repopulation, although this has not been thoroughly investigated. STUDY DESIGN: Laboratory-based comparative analysis. METHODS: Fifteen murine tracheas of strain C57/B-6 mice were obtained...

A carotid-carotid bypass is commonly used in debranching thoracic endovascular aortic repair. When the bypass graft is placed in the retroesophageal position, the esophagus may be compressed by the graft from behind. Therefore, dysphagia may occur postoperatively as a serious complication. To avoid this issue, we recommend placing the bypass graft below the cricoid cartilage.

BACKGROUND: Rhinophyma causes a nasal deformity and functional airway obstruction. Partial excision (eg, tangential) with secondary healing commonly removes hypertrophic soft tissues but does not improve nasal support. The subunit method for rhinophyma uses 6 nasal flaps to provide exposure for removal of rhinophymatous tissue and enhance structure. The purpose of this study was to evaluate outcomes of subunit method. METHODS: Medical records of patients with rhinophyma treated with the subunit method between 2013 and 2016 were analyzed...

INTRODUCTION: Osteochondral allograft (OCA) transplantation is generally effective for treating large cartilage lesions. Cleansing OCA subchondral bone to remove donor marrow elements is typically performed with pulsed lavage. However, the effects of clinical and experimental parameters on OCA marrow removal by pulsed lavage are unknown. The aim of the current study was to determine the effects on marrow cleansing in human osteochondral cores (OCs) of (1) lavage duration, (2) lavage flow intensity, and (3) OC sample type and storage condition...
