BACKGROUND: Surgical scar length is a common concern among patients undergoing Mohs micrographic surgery (MMS). OBJECTIVE: This study evaluates 3 metrics of preoperative lesion size to determine which correlates best with primary linear closure lengths for nonmelanoma skin cancers (NMSCs) treated with MMS. This metric is then used to develop predictive models for linear closure lengths in 10 different anatomical regions. MATERIALS AND METHODS: A retrospective study of 4,049 NMSCs treated with MMS and repaired with primary linear closure was conducted...

Matti Penttilä
BACKGROUND: The ostiomeatal complex (OMC), comprising a small natural maxillary sinus ostium and narrow infundibulum, transmits the air diffusion into the antrum and mucociliary transport from the antrum, and is considered a key area in chronic rhinosinusitis (CRS). Thin membranous anterior and posterior fontanelle areas below the OMC can rupture forming a perforation, accessory maxillary ostium (AMO), that increases antral airflow changing the anatomy and function of the sinus. The purpose of this study was to report the first case series of CRS patients who had undergone repair of fontanelle defects aiming to reconstruct normal structures...

Purpose: The rate of conventional aqueous humor outflow is the highest nasally. We hypothesized that this is reflected in regionally different outflow structures and analyzed the entire limbus by high-resolution, full-thickness ribbon-scanning confocal microscopy (RSCM). Methods: We perfused pig eyes by anterior chamber cannulation with eight lectin-fluorophore conjugates, followed by optical clearance with benzyl alcohol benzyl benzoate (BABB). RSCM and advanced analysis software (Imaris) were used to reconstruct a three-dimensional (3D), whole-specimen rendering of the perilimbal outflow structures...

The profile of the nose is an important feature for facial approximations. Although several manual and semi-automated prediction guidelines exist for estimating the shape of the nose, the reliability and applicability of these methods to South Africans groups are unknown. The aim of this study was to predict the displacements of capulometric landmarks from hard-tissue planes to facilitate nasal soft-tissue reconstruction in a South African sample. Cone beam computed tomography (CBCT) scans of 120 adult South Africans were selected from the Oral and Dental Hospital, University of Pretoria, South Africa...

Three-dimensional (3-D) printing is a method of manufacturing in which materials like plastic or metal are deposited onto one another in layers to produce a 3-D object. Because of the complex anatomy of craniomaxillofacial structures, full recovery of craniomaxillofacial tissues from trauma, surgeries, or congenital malformations is extremely challenging. 3-D printing of scaffolds, tissue analogs, and organs has been proposed as an exciting alternative to address some of these key challenges in craniomaxillofacial surgery...

BACKGROUND: The nasolabial flap is ideal for reconstruction of the nasal alar subunit due to its proximity, color and contour match, and well-placed donor scar. When raised as a random-pattern flap, there is a risk of vascular compromise to the tip with increased flap length and aggressive flap thinning. Surgical delay can greatly improve the chances of tip survival, allowing the harvest of longer flaps with greater reach. METHODS: We describe our technique of lengthening the nasolabial flap through multiple delay procedures...

Rajshree Jayarajan
BACKGROUND: Nasal reconstruction is a common plastic surgery procedure following cancer resection. Whereas most small and medium defects are managed using standard local flaps, reconstructive options available for large defects of the nose such as a heminasal defect are very few. Most of the large defects are usually managed using a forehead flap, which involves at least 2 stages or using free tissue transfer. The author describes a combination flap that can be used for reconstruction of heminasal defects as well as lateral wall defects...

INTRODUCTION: Surgical excision of large malignant lower eyelid tumors may cause important full-thickness eyelid defects. The reconstruction of such defects must restore the physiologic function of the eyelid and also re-establish an acceptable aesthetic result. MATERIALS AND METHODS: We report the outcomes of full-thickness excision of tumors extending over half of the horizontal lid length, followed by reconstruction using a nasal chondromucosal graft (coming from the ipsilateral ala of the nose) and an upper eyelid myocutaneous flap...
