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...

PURPOSE: To evaluate which respiratory support method for critically ill patients undergoing endotracheal intubation (ETI) is associated with less desaturation. METHODS: We searched PubMed, Cochrane Library, Scopus and CINAHL databases. We included randomized (RCT) and non-randomized (non-RCT) studies investigating any method of respiratory support before/during ETI compared to a reference control. RESULTS: Apneic oxygenation (ApOx) was the most commonly investigated respiratory support technique for critically ill patients undergoing intubation (4 RCTs, 358 patients)...

The air-conditioning characteristics of the human nasal cavity were investigated using computational fluid dynamics. The wall layer was modeled as a heat conducting layer consisting of water with constant thickness placed on top of epithelial cells. By assuming constant tissue temperature, prescribed to be 36 (°)C, which is close to the alveolar condition, the proposed wall model yielded a spatially varying surface temperature distribution that is in reasonable agreement with the measurement studies in the literature...

OBJECTIVE: To further characterize the clinical utility of AVP-825 based on additional prespecified outcomes and post hoc analyses of COMPASS, a Phase 3 comparative efficacy trial of AVP-825 vs 100 mg oral sumatriptan (NCT01667679). AVP-825 was approved in January 2016 by the US Food and Drug Administration under the name ONZETRA(®) Xsail(®) (sumatriptan nasal powder) for the acute treatment of migraine with or without aura in adults. BACKGROUND: AVP-825 is a delivery system that uses a patient's own breath to deliver low-dose sumatriptan powder to the upper posterior regions of the nasal cavity beyond the narrow nasal valve, areas lined with vascular mucosa conducive to rapid drug absorption into the systemic circulation...

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...

Pneumatocele of the lacrimal sac is an uncommon entity and has been rarely reported in literature. The valvular function of the Hasner's valve at the lower end of nasolacrimal duct is presumed to prevent the retrograde reflux of air into the lacrimal sac with increased intranasal pressure as in valsalva maneuver. Loss of this valvular function as noted with persistent positive airway pressure ventilation can cause retrograde air reflux into lacrimal sac. The authors report a case of lacrimal sac pneumatocele which developed following blunt nasal trauma involving the bony nasolacrimal duct...

The nose forms the first 8 cm of the upper respiratory tract and is responsible for cleansing, humidification, and temperature control of the supplied air. This is also referred to as conditioning. The nasal valve region, formed by the head of the lower nasal concha, portions of the cartilaginous septum, and the upper lateral cartilage, is responsible for diffusing and accelerating the respiratory airflow. Prerequisite are regular mucociliary clearance and sufficient air passage. Hypertrophy of the lower nasal turbinate is one of the most common causes of symptomatic nasal congestion...

Peripheral paralysis of the facial nerve is the most frequent of all cranial nerve disorders. Despite advances in facial surgery, the functional and aesthetic reconstruction of a paralyzed face remains a challenge. Graduated minimally invasive facial reanimation is based on a modular principle. According to the patients' needs, precondition, and expectations, the following modules can be performed: temporalis muscle transposition and facelift, nasal valve suspension, endoscopic brow lift, and eyelid reconstruction...

By convention, a "deviated nose" is one in which the lower third is asymmetric with regard to the midline. The lower third of the nose is composed of the lower cartilages, as well as the dorsal and caudal nasal septum. Not only does the deviated nose cause a cosmetic deformity that is often disconcerting for patients, but it may also be associated with functional problems. Airway obstruction may result from a narrowed internal nasal valve in the middle third or from a deviated caudal septum in the lower third...

Understanding nasal anatomy and physiology are the most important points for successful functional rhinoplasty. Anatomic structures playing major roles in nasal breathing functions include the septum, and internal and external nasal valves, so physical examination of these regions is essential. Planning for functional rhinoplasty involves the identification of the sites of nasal airway obstruction or old trauma, and addressing those regions during the operation with a number of different techniques that have been described...

REVIEW
Grant S Hamilton
The external nasal valve is a complex entity comprised of multiple structures and tissue types. As such, there is no single operation that can address all problems of the external valve. This article reviews the relevant anatomy, pathologic conditions, and treatments for external nasal valve dysfunction, including a detailed review of the nasal muscles and their contribution to external nasal valve patency. Surgical and nonsurgical options for treatment and the evidence supporting the importance of proper external nasal valve function on quality-of-life measures are discussed...

Importance: Nasal reconstruction after Mohs surgery is a unique challenge in that it must satisfy both functional and aesthetic goals. Despite some advocacy in the literature for using structural reinforcement to achieve both functional and aesthetic outcomes in soft-tissue reconstruction, no study has validated this claim by comparing reconstruction with and without structural support. Objective: To evaluate the effectiveness of and need for structural reinforcement when reconstructing the nasal alar and sidewall subunits...

<p>Surgical defects located within 5 mm of the nasal alar margin are at risk for alar elevation or collapse of the external nasal valve during wound healing. To reduce the chance of such complications, free cartilage grafts may be used as part of the reconstruction. However, if the defect is large enough so that the free cartilage graft does not fill most of the defect, wound contraction can still lead to alar displacement. In these situations, skin may need to be recruited from either the forehead or cheek in the form of an interpolation flap to cover both the free cartilage graft and the residual cutaneous defect...

AIM: The role of transoesophageal echocardiography in cardiac interventional structural procedures is well established and appreciated. However, the need for general anaesthesia (GA) throughout the procedure remains a controversial issue. The aim of the present study is to assess the feasibility and imaging quality of using a transnasal microrobe that allows the usage of conscious sedation in patients who undergo cardiac structural interventional procedures without missing the benefits, guidance and navigation of conventional trans-procedural TEE...

Importance: Internal nasal valve (INV) collapse is a common cause of nasal obstruction, and spreader grafts are the established standard of treatment. Recently, spreader flaps have gained attention in the treatment of nasal valve stenosis when performed in conjunction with dorsal hump reduction. To date, the efficacy of the spreader flap technique without dorsal hump reduction has not been previously described. Objective: To determine whether spreader flaps are equivalent to spreader grafts in correcting INV collapse in the absence of simultaneous dorsal hump reduction...

The nasal valve area is the functional area that allows airflow regulation. It could be divided in an internal area and an external one, basing on the anatomical landmarks. Many conditions can damage these areas with a consequently nasal obstruction, more often in particular extended rhinoplasty and sequels of facial trauma. To restore this area many techniques were advocated during the last decades.In this article the authors investigate on valve areas deficiency in sequel of rhinoplasty proposing a structural approach through alar batten grafts to correct internal-external nasal valves collapse...
