[OBJECTIVES] Long-term aesthetic outcomes following head and neck (HNC) microvascular free flap reconstruction are poorly understood. As patient survival improves for HNC, it is critical to understand the impact of surgical treatment upon a…

[OBJECTIVE] Hardware exposure after microvascular free tissue transfer (MFTT) for mandibular reconstruction is a significant complication. While osteocutaneous MFTTs are the preferred option, some patients require soft tissue-only MFTTs due…

[OBJECTIVES] While prior studies have demonstrated favorable aesthetic outcomes using skin grafted free flaps to improve recipient site color match (Epithelial Preservation Including Dermal Resection Microvascular technique: EPIDERM techniq…

Computer-aided design and manufacturing can enhance microvascular mandible reconstruction, particularly in cases with preexisting segmental defects or exophytic tumors where precise in situ plate bending is difficult. However, its high cost…

Retrospective cohort study. To (1) assess post-operative quality of life (QOL) and functional outcomes of fibula free flap (FFF) donor sites, (2) examine the incidence of post-operative claw toe deformities (CTDs) following FFF harvest, an…

[BACKGROUND] There are no current best practice guidelines for management of pharyngoesophageal perforation (PEP), a rare complication of anterior cervical discectomy and fusion (ACDF). We describe our institution's experience with free fla…

[BACKGROUND] Social determinants of health (SDH), such as race, language, and insurance status, may impact access to surgical care and postoperative outcomes. This study investigates the role of SDH in patients undergoing osteocutaneous fre…

Gender-affirming facial surgery is increasing in prevalence, and rhinoplasty plays an integral role in its success. The nose displays considerable gender dimorphism, and maneuvers performed during gender-affirming rhinoplasty may differ con…

[OBJECTIVES] To evaluate the impact of transfemale gender-affirming rhinoplasty on nasal appearance as evaluated by common facial analysis measures. [METHODS] Retrospective case series of patients undergoing gender-affirming nasal surgery …

[OBJECTIVE] To measure the increase in effective pedicle reach with microdissection of musculocutaneous perforators during anterolateral thigh (ALT) free tissue harvest. [METHODS] A review of our institution's free flap database was perfor…

[OBJECTIVES] Microvascular free tissue transfer is routinely used for reconstructing midface defects in patients with malignancy, however, studies regarding reconstructive outcomes in invasive fungal sinusitis (IFS) are lacking. We aim to d…

[OBJECTIVES] To use portable colorimetry to quantify color differences between facial skin and potential three head and neck microvascular free tissue transfer (MFTT) donor sites-radial forearm (RF), anterolateral thigh (ALT), and fibula (F…

[BACKGROUND] Complications following head and neck microvascular free tissue transfer (MFTT) are common. Less is known about when they occur. [METHOD] Retrospective study of patients with primary or recurrent head and neck cancer undergoin…

[OBJECTIVE] Women represent an increasing proportion of the otolaryngology workforce. Work-related musculoskeletal disorders (WRMSD) are a little-studied yet important impediment to career completion. Scant attention has been directed to st…

The factors that contribute to postoperative trismus after mandibulectomy and fibula free flap reconstruction (FFFR) are undefined. We retrospectively assessed postoperative trismus (defined as a maximum interincisal opening ≤35 mm) in 106 …

An anterior thigh split thickness skin graft (AT-STSG) is frequently needed to close the radial forearm free flap (RFFF) donor site, conferring morbidity to two extremities. The anterolateral thigh (ALT) free flap is virtually always closed…

Parotidectomy defects can leave patients with considerable functional and cosmetic deformities. We aim to compare the success rates and complications associated with vascularized versus nonvascularized adipofascial grafts for reconstruction…

[BACKGROUND] Postoperative seroma is the most common donor site complication following anterolateral thigh (ALT) free flap harvest for head and neck reconstruction. The utility of novel microporous polysaccharide hemospheres (MPH) has not b…

Anterolateral thigh (ALT) microvascular free tissue transfer is an integral part of head and neck reconstructive surgery, but it can be complicated by postoperative donor site fluid collections. To measure the rate of hematoma and seroma f…

[OBJECTIVES/HYPOTHESIS] To quantify the degree of color match achieved during microvascular facial reconstruction, and to describe a novel technique for improving reconstructive skin color match. We hypothesize that split-thickness skin gra…

Gender-affirming facial surgery (GFS) is pursued by transgender individuals who desire facial features that better reflect their gender identity. Currently, there are a few objective guidelines to justify and facilitate effective surgical d…

[OBJECTIVE] Papaverine is a topical vasodilator commonly used during microvascular surgery to inhibit undesired vasoconstriction. A previous national shortage of papaverine prompted evaluation of an alternative, effective vasodilator. This …

[OBJECTIVE/HYPOTHESIS] For patients undergoing microvascular free tissue transfer (MFTT), we evaluated risk factors and financial implications of operating room (OR) take-back procedures. [STUDY DESIGN] Retrospective review at a tertiary c…

[OBJECTIVES/HYPOTHESIS] To better understand aesthetic patient-reported outcomes and psychosocial quality of life (QOL) after head and neck microvascular reconstruction for benign or malignant tumors. [STUDY DESIGN] Single-center prospecti…

Radical parotidectomy may result from treating advanced parotid malignancies invading the facial nerve. Survival is often enhanced with multimodality treatment protocols, including postoperative radiation therapy. In addition to the reconst…

[OBJECTIVES/HYPOTHESIS] To assess the accuracy and utility of positron emission tomography/computed tomography (PET/CT) compared with magnetic resonance imaging (MRI) for detecting head and neck cancer (HNC) recurrence after microvascular r…

Aesthetically pleasing and functionally stable total maxillectomy reconstruction is among the greatest of challenges within head and neck surgery. Maintaining presurgical midface projection, contour, and cheek volume requires high-fidelity …

[IMPORTANCE] The fibula free flap donor site is associated with both short-term and long-term morbidity. Split-thickness skin graft (STSG) loss can lead to long delays in donor site healing and is associated with significant adverse sequela…

[OBJECTIVES/HYPOTHESIS] Machine learning (ML) is a type of artificial intelligence wherein a computer learns patterns and associations between variables to correctly predict outcomes. The objectives of this study were to 1) use a ML platfor…
