Direct primary closure without undermining in the repair of vermilionectomy defects of the lower lip

Vermilionectomy followed by reconstruction of the vermilion mucosa using allograft dermal matrix in patients with actinic cheilitis of the lower lip

BACKGROUND

When treating actinic cheilitis (AC), it is essential to minimize the risk of malignant transformation (MT) and maintain lip functionality and cosmesis.

AIMS

We evaluated the outcomes of vermilionectomy followed by reconstruction of the vermilion mucosa using allograft dermal matrix (ADM) in patients with AC of the lower lip.

MATERIALS AND METHODS

We evaluated eight patients with lower lip AC who underwent vermilion mucosa reconstruction using ADM after vermilionectomy. We enrolled five males and three females ranging in age from 55 to 70 years (mean, 62.1 years). The ADM ranged in area from 1.3 × 5.0 to 1.7 × 5.8 cm (median, 1.6 × 5.5 cm). All patients were followed up for at least 3 months postoperatively by a panel of three surgeons who assessed the esthetic results, and orbicularis oris and speech functions.

RESULTS

All patients underwent successful reconstruction of the vermilion mucosa using ADM after vermilionectomy, without complications. The postoperative esthetic results, and the orbicularis oris and speech functions, were satisfactory to excellent in all patients. Patients were followed up for 18-38 months (median, 26.1 months). No MT or recurrence was noted.

CONCLUSIONS

Vermilionectomy followed by reconstruction of the vermilion mucosa with ADM is safe and feasible for AC patients.

Myomucosal Lip Island Flap for Reconstruction of Small to Medium Lower Lip Defects

Importance: Reconstruction of small to medium lower lip defects commonly includes mucosal advancement and wedge excision with primary closure, resulting in aesthetic complications such as lip flattening, shortening, and loss of the vermilion roll. The myomucosal lip island flap offers an alternative that preserves lower lip appearance and function.

Objective: To describe the lateral myomucosal lip island flap and its indications for the reconstruction of small to medium lower lip defects.

Design, Setting, and Participants: A retrospective chart analysis of patients from 2014 to 2019 was done. Participants include all consecutive patients of the senior author who had the myomucosal lip island flap employed in the lower lip from 2014 when the senior author began employing this technique, including 20 patients. Patient demographics, surgical indications, surgical defect bridging distances, flap advancing distances, functional complications, and aesthetic outcomes were reported. IRB approval was obtained from St. Joseph Health Center for Clinical Research and surgeries were performed at a private tertiary referral center—Skin Cancer and Reconstructive Surgery Center—by the senior author in a multispecialty practice.

Main Outcomes and Measures: Location and flaps utilized to reconstruct the defect were reported. Lateral advancing distance and overall bridging distance were measured. Functional complications, if any, were reported. Appearance rating after the first stage was assessed.

Results: This case series included 20 patients with lower lip defects reconstructed with myomucosal lip island flaps. The average bridging distance (width of defect) was 1.7 cm (minimum 1.0 cm, maximum 2.8 cm). Of 18 patients with available postoperative photographs, 4 cases (22%) had mild vermilion inferior retraction, 1 case (6%) had mild contour irregularity, and 1 case (6%) had visible white scar in the red lip.

Conclusions and Relevance: The myomucosal lip island flap is a reliable technique for reconstruction of small to medium lower lip defects, preserving lip fullness and the vermilion roll.

Daylight photodynamic therapy for the treatment of actinic cheilitis

BACKGROUND

Actinic cheilitis (AC) is a common, chronic premalignant condition resulting from protracted sun exposure affecting the vermilion border of the lower lip. Treatment of AC aims at terminating the progression to squamous cell carcinoma by obliterating the primary lesion, and includes ablative methods; nonablative modalities such as cryotherapy, electrodessication, chemical peeling, topical imiquimod and 5-fluorouracil; and photodynamic therapy (PDT). Daylight-activated PDT, in which natural daylight serves as the light source, showed promising results in the treatment of actinic keratoses with substantially less pain than conventional PDT.

PURPOSE

To determine the safety and efficacy of daylight PDT in a series of patients with AC.

METHODS

Eleven patients with AC were treated with daylight PDT. All patients underwent repeated treatment sessions until clinical and histological remission were achieved.

RESULTS

Cure rate was 91% (10 of 11 patients, three females/eight males; mean age 59.2 ± 14.4 years). Mean number of treatments to attain cure was 2.7. Patients experienced mild erythema and minimal to no pain during treatment.

CONCLUSIONS

Daylight PDT is a promising modality for the treatment of AC, with impressive cosmetic results and few side effects.

Simplifying Lip Reconstruction: An Algorithmic Approach

The authors provide an overview of lip reconstruction after Mohs surgery based on the senior author's practice. Lip reconstruction offers unique challenges to preserve not only lip function but also aesthetics. Lip reconstruction must take into consideration the three anatomical layers that comprise the lip and defects that involve the mucosa, the muscle, the skin or more than one layer will help determine the modality of repair. The authors offer an algorithm based on defect location, tissue involvement, and severity of defect to simplify an often complex decision-making process.

Total lower lip and chin reconstruction with radial forearm free flap: A novel approach

BACKGROUND

The management of large chin and lower lip defects is challenging due to this facial subunit's tremendous functional and aesthetic importance. Specific methods for total lower lip and mentum reconstruction are not well chronicled. Aesthetic and functional goals of this reconstruction include restoration of oral competence by maintaining lower lip height, vermilion reestablishment, color-matched skin introduction to the chin, sensation restoration, and ideally restoration of dynamic activity to the lower lip.

METHODS

Literature review performed.

RESULTS

Presentation of novel, two-stage technique for lower lip and chin reconstruction with a submental flap and a radial forearm free flap, suspension of the lower lip and chin with a tensor fascia lata graft, and vermilion reconstruction with a buccal mucosal flap.

CONCLUSIONS

This procedure meets all goals of total lower lip reconstruction with the exception of the introduction of dynamic tissue and represents a novel solution to a challenging reconstructive problem.

Sore or Swollen Lips Part 3: Diagnosis and Treatment

This series of three papers reviews the causes, diagnosis and differential diagnosis, and outlines the management of sore and/or swollen lips. Clinical relevance: Sore and/or swollen lips are not uncommon, often have a local cause but may reflect a systemic disease. The previous 2 papers in the series discussed their causes. This paper reviews their diagnosis and treatment.
