Scientific Analysis of Phenol Nail Surgery

The human nail is a complex unit that includes five major modified cutaneous structures: the nail matrix, nail bed, nail plate, nail folds, and cuticle (eponychium). This chapter discusses the function and structure of the five nail components and the pathophysiology affecting each. Also reviewed are nail findings associated with underlying systemic and dermatologic conditions: splinter hemorrhages, koilonychia, transverse nail-plate depressions (Beau’s lines), onycholysis, leukonychia, clubbing, nail-plate pitting, and longitudinal pigmented bands. Infections of the nail are discussed, which include bacterial paronychia, chronic paronychia, and onychomycosis. Figures illustrate the longitudinal section of the fingernail, multiple pigmented longitudinal bands, psoriasis involving the fingernail, late-stage lichen planus of the fingernail, transverse linear grooves, Pseudomonas aeruginosa causing a green nail, psoriasis of the nail, melanonychia striata, and a nail specimen for potassium hydroxide preparation. Tables describe antifungal treatment for toenail onychomycosis as well as selected dermatologic disorders that affect the nail unit. This chapter contains 50 references.

Types Of Information

To the Editor.— The commentary, "The Attack on the Tympanic Membrane,"1 "calls for some comments as the author referred to a preliminary report of my study.2 Stickler1 suggests that we "demand prospective studies of untested surgical procedures before our patients are subjected to them," and nobody can disagree with that. However, the aim of such investigations is to arrive at a scientific analysis that is based on a weighing of the pros and cons. This process is going on concerning the use of ventilation tubes in secretory otitis media and, if a status has to be made, both types of information should be evaluated.

Abstract Background Nail psoriasis occurs frequently in patients with psoriatic disease, it can lead to functional impairment, pain, discomfort, decreased quality of life and can also be a predictor for the development of arthritis. Early recognition of this condition can provide early and effective treatment and prevent structural impairment. This study aims to identify nail ultrasonographic characteristics in three groups: psoriasis (PsO), psoriatic arthritis (PsA) and controls patients, to determine if the ultrasonography (US) can identify early signs of nail psoriatic impairment or local inflammation. We conducted nail US to determine nail matrix resistance index (NMRI), nail bed resistance index (NBRI), and power Doppler (PD) and grayscale (GS) parameters in these 3 groups. Methods Single-center, cross-sectional study. GS, PD, and spectral doppler images of bilateral 2nd and 3rd fingernails were acquired from 35 PsO, 31 PsA, and 35 controls patients. An US equipment with an 18 MHz linear transducer for GS and 8.0 MHz for PD was used. PD, NMRI, NBRI, nail plate thickness (NPT), nail bed thickness (NBT), nail matrix thickness (NMT), and morphostructural characteristics of the trilaminar structure (TS) were evaluated in saved images, blind. Results Mean NMRI and NBRI did not differ between groups. Linear regression analysis detected no relationships between PsO or PsA and NMRI or NBRI. Nail PD grade did not differ between groups. Type I and IV TS changes were more frequent in PsO; types II and III changes were more frequent in PsA (p < 0.001). NPT was greater in PsA and PsO groups than controls: PsA 0.73 ± 0.14 mm, PsO 0.72 ± 0.15 mm, Controls 0.67 ± 0.10 mm (p = 0.001). Conclusion Echographic TS characteristics of the nail plate and NPT evaluated by GS are useful and can distinguish PsO and PsA nails from controls. NMRI, NBRI, and US nail microcirculation parameters could not distinguish psoriatic nails.

<p>Total nail ablation for the treatment of onychodystrophies can be performed by using chemicals, surgical resection or laser ablation of nail matrix.<strong> </strong>A female patient with bilateral severe onychodystrophy as a result of inadvertent previous nail surgeries was treated surgically. Proximal complete nail matrix resection and distal 10 mm wide transverse strip partial nail bed resection were performed. A 5 mm wide transverse strip of nail bed was left intact proximally. Proximal nail matrix defect was closed by using the skin of proximal nail fold. The distal nail bed defect was reconstructed by using triple flap technique which was composed of a main central advancement flap containing ventral toe skin and two side flaps containing nail fold skin. The patient healed without any problem and her nail problem was treated successfully. The cosmetic appearance of her first toes was acceptable. Surgical nail ablation followed by volar skin coverage of dorsal surface of the distal phalanx bone by using triple flap technique is an effective surgical treatment method for the correction of advanced nail plate deformities requiring total nail ablation. </p>
