Karapandzic flap and Bernard-Burrow-Webster flap for reconstruction of the lower lip

Reconstruction of extensive lower lip defects using vascularized mucosal flap with external skin complex tissue

BACKGROUND

The complexity of lip anatomy and the roles played by the lip make the reconstruction of lip defects more challenging. Adequate reconstruction of lip defects requires adaptation of mucosa, vermilion, and skin features in lip as well as its specific function.

METHODS

A 59-year-old male with left lower lip cancer underwent en-bloc resection and left selective neck dissection (SND), followed by immediate reconstruction using Facial Artery Myomucosal Island Flap (FAMMIF) with external Skin Complex Tissue.

RESULTS

The use of chimeric flap based on FAMMIF and its external skin tissue allowed minimizing the postoperative problem of combination of both aesthetic and functional impairments. The FAMMIF is suitable for the reconstruction of lip mucosa and lip vermilion, while the external skin tissue can be use to replace the external lip skin defect. The patient was satisfied with the treatment outcomes. He is undergoing follow-up without any evidence of recurrence.

CONCLUSION

FAMMIF with external skin complex tissue, as a reconstructive approach selected in our case of lip defect secondary to lip cancer resection, combined the reconstruction of both aesthetics and functions of the lower lip. The technique was found feasible and provided satisfactory postoperative outcomes.

Application of vermillion myocutaneous flap in restoration after lip cancer resection

To investigate the application of the vermillion myocutaneous flap in restoration after lip cancer resection. From July 2012 to December 2019, six patients with lip cancer admitted in our department were included in this study. Total defect of the whole layer of the lip, accounted for 1/3 to 1/2 of the total length of the lip after tumor resection, were repaired by vermillion myocutaneous flap. For the case defect presenting >1/2 of the total length of the lip, a local rotational flap was designed with vermillion myocutaneous flap compound to repair the defect. At present, the patients were followed up for 6 months to 7 years. There was no tumor recurrence. The aesthetic effects and function of lip after operation were ideal, with satisfactory outcomes. Vermillion myocutaneous flap with the labial artery as the axis was an effective method to restore the anatomical structure and function of the lip. In the presence of a defect area of larger than 1/2 of the length of the whole lip, local skin flap can be used for simultaneous repair in order to achieve satisfactory outcome.

Branching Patterns of Mental Nerve in Newborns

In classical textbooks of Anatomy, the mental nerve is considered to be the terminal or main branch of the inferior alveolar nerve, especially trifurcate with no designated names as soon as it emerges from the mental foramen. The textbooks define the innervation area of the mental nerve regionally without naming its terminal branches. Nomina Anatomica designates 3 terminal branches of mental nerve as "labial, gingival, and mental branch" but offers no description about their distribution on the mandible. In the present study, bilateral dissections were performed on the lower lip specimens of 20 newborns for 40 mental nerves to determine the branching types of mental nerve. Although anatomy textbooks indicate that mental nerve divides into 3 branches, the authors noted that mental nerve branched into 1, 2, or 3 branches at or right after its exit from the mental foramen. Branching patterns were typed in 13 different subclasses under 3 main groups (Form I-II-III). Moreover, the branching patterns that could not be included in one of these 3 main groups were defined as "Complex Form." The most common type of branching that the authors observed was Form II, which had 2 terminal branches with an incidence of 41.9% (16 specimens). The next frequently encountered type was Form III, having 3 terminal branches, and it was detected in 32.0% of patients (12 specimens). The least common form was Form I, which had 1 terminal branch with a frequency of 15.8% (6 specimens). The unclassified group, Complex Form, was found 10.5% (4 specimens).

Comprehensive Treatment of Upper Lip Arteriovenous Malformation

Arteriovenous malformations are uncommon congenital disorders in vascular development. They frequently involve craniofacial structures and result in a morphogenic abnormality with ominous arteriovenous shunting. We present a huge AVM of the upper lip in an 18-year-old patient who was successfully treated by the combination method of presurgical endovascular embolization and complete resection of the lesion. Subsequent surgical defect in upper lip, which involved more than two-third of the lip length, was reconstructed via Webster's modification of cheek advancement flap.

Two-Piece Extraoral Prosthetic Rehabilitation to a Perineural Invasion Lip Cancer

Lip cancers can severely affect a person in terms of function, esthetics, and psychological trauma. After surgical resection, lip defects require special rehabilitation. This clinical report describes a neck prosthesis of a male patient diagnosed with lower lip squamous cell carcinoma with perineural involvement. The neck prosthesis was connected to the mandibular complete denture with cobalt samarium magnets. Both prostheses improved the patient's mastication, deglutition, and esthetics.

Combined Submental-tongue Flap for Reconstruction of Subtotal Traumatic Avulsion of Lower Lip: A Technical Note

Delayed reconstruction of large lower lip defects after traumatic avulsion is a challenge in medically compromised patients with concomitant cheek skin burn. Combination of orthograde submental transposition flap and anteriorly based ventral rectangular myomucosal tongue flap is useful. The former reconstructs the body of the defect, and the latter masks the red lip, resembling vermilion. In this article, the detailed surgical technique is explained. Literature review of tongue flap and submental flap in the lower lip reconstruction is presented.

Reconstructive surgery in advanced perioral non-melanoma skin cancer. Results in elderly patients

BACKGROUND

Nonmelanoma skin cancer (NMSC) of the perioral region is not uncommon. Basal cell carcinoma is predominant in the upper lip area and squamous cell carcinoma in the lower lip area. While smaller lesions can be treated by excision followed by primary closure larger defects after tumor surgery can be challenging.

OBJECTIVES

Analysis of outcome after complete surgical excision with micrographical control of excision margins (delayed Mohs surgery) of large NMSC's of the perioral region (lips and chin).

PATIENTS AND METHODS

This is a retrospective, single-center analysis of patients with defects after delayed Mohs surgery of ≥ 3 cm of the perioral region. The study included a total of 25 patients (4 women and 21 men) with a mean age of 83.7 years. Twenty patients were diagnosed with squamous cell carcinoma and five had basal cell carcinoma. The lower lip was affected in 19 patients, the upper lip in 4 patients and the chin in 2 patients. Tumor stage was either T1N0M0 or T2N0M0. The most common procedure for lower lip defect closure was staircase or modified staircase technique. Cheek advancement flaps were used for upper lip defect closure. Inferiorly based nasolabial rotational flap, cheek rotational flap and modified Webster flap were also employed. In one patient Webster flap and unilateral staircase technique were combined.

RESULTS

In all patients the tumor was removed completely with preservation of function and aesthetics. No local recurrence was observed after a median follow-up of 4.9 years.

CONCLUSION

Perioral reconstruction after removal of large NMSC is a complex issue. The age group of over 70 years, frequently with comorbidities, requires a robust surgical technique with short operation times and tailored approaches for defect closure.

Experience with esthetic reconstruction of complex facial soft tissue trauma: application of the pulsed dye laser

BACKGROUND

Facial soft tissue injury can be one of the most challenging cases presenting to the plastic surgeon. The life quality and self-esteem of the patients with facial injury may be compromised temporarily or permanently. Immediate reconstruction of most defects leads to better restoration of form and function as well as early rehabilitation.

OBJECTIVES

The aim of this study was to present our experience in management of facial soft tissue injuries from different causes.

PATIENTS AND METHODS

We prospectively studied patients treated by plastic surgeons from 2010 to 2012 suffering from different types of blunt or sharp (penetrating) facial soft tissue injuries to the different areas of the face. All soft tissue injuries were treated primarily. Photography from all patients before, during, and after surgical reconstruction was performed and the results were collected. We used early pulsed dye laser (PDL) post-operatively.

RESULTS

In our study, 63 patients including 18 (28.5%) women and 45 (71.5%) men aged 8-70 years (mean 47 years) underwent facial reconstruction due to soft tissue trauma in different parts of the face. Sharp wounds were seen in 15 (23%) patients and blunt trauma lacerations were seen in 52 (77%) patients. Overall, 65% of facial injuries were repaired primary and the remainder were reconstructed with local flaps or skin graft from adjacent tissues. Postoperative PDL therapy done two weeks following surgery for all scars yielded good results in our cases.

CONCLUSIONS

Analysis of the injury including location, size, and depth of penetration as well as presence of associated injuries can aid in the formulation of a proper surgical plan. We recommend PDL in the early post operation period (two weeks) after suture removal for better aesthetic results.

Surgical options for treatment of lip and perioral tumors: report of 5 cases

Basal cell and squamous cell carcinomas are the main neoplasms of lip and perioral location. We describe different techniques of successful surgical reconstruction, including flaps or simple incision and suture. Using the latter technique satisfactory results were demonstrated, although the incision made removed more than a third of the lip, contrary to the literature. Our goal is to emphasize that the common sense and experience of the surgeon should prevail in the choice of reconstructive method. Moreover, even if the priority is complete excision of the lesion, we cannot ignore the aesthetic and functional recovery objective.

Reconstruction of medial lower lip defects after tumour surgery: modified staircase technique

The most common cancer of the lower lip is squamous cell carcinoma (SCC). Micrographically controlled surgery (Mohs surgery) is the golden standard of therapy in localized SCC. Since the majority of lip cancer patients is >60 years of life, planning of surgery and reconstruction has to consider the age and co-morbidities. The staircase or step technique is a robust method to achieve a good functional reconstruction in a one-step procedure. We also describe a modified staircase technique when SCC is not infiltrating the orbicularis oris muscle.

Yu's flap for lower lip and reverse Yu's flap for upper lip reconstruction: 20 years experience

Reconstruction of defects of the lip caused by cancer with its requirements of a complicated anatomical structure, important physiological function, and acceptable cosmetic result, is a challenge for oral and maxillofacial and plastic surgeons. A method that combines rotation and advancement flaps was described by Yu in 1989 for the reconstruction of defects of the lower lip. In our department between January 1992 and December 2012, 8 patients had reverse Yu flaps for the reconstruction of upper lip defects and 56 patients had classic Yu flaps for lower lip defects. Patients with defects located laterally to the upper lips, ranging from ⅓ to ½, had unilateral reverse Yu flaps, and bilateral procedures were done for defects of less than ⅔ of the lips. However, if the defects were located in the centre of the upper lips, between ⅓ and ½, they were treated with bilateral reverse Yu flaps. Patients with defects between ⅓ and ⅔ of lower lips had unilateral Yu flaps, and if the defects were wider than ⅔ of the lower lips, the procedure was bilateral. No flap failed and desirable functional and aesthetic outcomes were recorded in all cases. Here we report our experience with the Yu flap for the benefit of other surgeons.

[Post-traumatic reconstruction of the lower lip after total or subtotal amputation using the Webster's modification of the Bernard cheiloplasty -- advantages, disadvantages and limitations: three cases]

Webster's modification of the Bernard cheiloplasty is a well-known technique, usually applied to the reconstruction of total or subtotal amputations of the lower lip following oncological resection. We present three cases of post-traumatic reconstructions with interesting results.
