The face is an important structure, because it is the most visible part of the body and contains delicate and complex elements that are essential for aesthetics and functionality. Facial reconstruction of areas with substantial substance loss remains a surgical challenge. There are several repair options, with corresponding advantages and disadvantages. We present a case of a patient with substance loss of the total thickness of the cheek region who received mucosal and local skin flap surgery, with good results and functional preservation.

A face representa uma estrutura importante nos seres humanos, devido a ser a parte mais visível do corpo e conter elementos delicados e complexos, que são essenci ais em termos de beleza e funcionalidade. As reconstruções faciais, em áreas de grandes perdas de substâncias, permanecem como um desafio para os cirurgiões. Apresentam várias opções de reparo, todas com suas vantagens e desvantagens. Mostramos o caso de um paciente apresentando perda de substância de espessura total em região de bochecha, que foi submetido à associação de retalho mucoso e retalho cutâneo local, apresentando bom resultado e preservação funcional.

The face is an important structure because it is the most visible part of the body and contains delicate and complex elements that are essential for aesthetics and functionality1.
From an aesthetic point of view, the cheek area can be divided into three units according to location: suborbital, preauricular, and buccomandibular2. The buccomandibular region is comprised of four layers: the skin, subcutaneous region, superficial musculoaponeurotic system (SMAS), and oral mucosa, that are reconstructed in multiple surgical planes.
Many forms of reconstruction have been described, from the superficial layer to the oral mucosa.
Primary closure, partial and full skin grafts, local flaps (cutaneous and myocutaneous), free flaps, and tissue expansion have been described as options for reconstruction of the superficial plane1-10.
Mucosal defects in the oral cavity resulting from tumor resections or acute or chronic infectious processes may cause significant functional and aesthetic deficits, but can be reconstructed with primary closure, closure by secondary intention with mucosalization, skin grafting, tongue flap, local skin flaps, and free flaps7,9.
A 33-year-old male mulatto university student from Pirapora, Minas Gerais, was single, HIV-positive, and had a history of tonsillitis six years prior, which evolved to bilateral facial cellulitis (oral region). He was initially treated with penicillin, but had an allergic reaction and remained hospitalized for (unnamed) antibiotic therapy. The cellulitis evolved to abscess and local necrosis. The left side closed spontaneously, but the right side had a large area with total thickness loss of substance. A graft was attempted at the time without satisfactory results.
On examination, we found significant bilateral facial atrophy and extensive areas with loss of substance on the right side, as shown in Figures 1 and 2. During the previous six years, the patient used occlusive dressings, changing them several times daily and whenever he ate.

His infectious disease was monitored frequently, he correctly used his prescribed antiretroviral therapy, and did not have contraindications to surgery.
The patient was placed under general anesthesia, with skin and oral cavity antisepsis therapy. First, an incision was made on the border between the skin and oral mucosa regions (mucosalization), with dissection of the mucosal plane, to form two mucosal flaps. Sutures were inserted two planes to preserve the mucosal layer in the intraoral region (Figures 3, 4, and 5).

Next was dissection of the skin flap in the supra-SMAS plane of the third middle facial region to fabricate a lateral transposition flap and closing by planes, followed by site dressing (Figures 6 and 7).

After surgery, the patient underwent antibiotic treatment with clindamycin as well as vacuum aspiration drainage.
On the seventh day after the procedure, the patient presented with a small skin flap with purulent local secretion at the edges. Ciprofloxacin and metronidazole antibiotics were prescribed for seven days, with good performance and closure by secondary intention. Thus, the procedure provided satisfactory results, with no salivary fistula, preservation of masticatory function, and maintenance-free dressings (Figures 8, 9, and10).

Facial reconstruction of areas with large loss of substance remains a challenge for surgeons1,3. There are several repair options with corresponding advantages and disadvantages1.
Skin grafts are a simple option with little associated morbidity, but the grafts are often a different color and thickness compared to the receiving region, and consequently have generally unsatisfactory aesthetic results1,3,6.
Free flaps are an excellent choice, but the procedure requires appropriate structure and staff with microsurgery experience. They may present complications such as infection, thrombosis, and flap loss3,4,8,9.
Local flaps, as presented here, are often a good choice because they offer matching skin color and similar texture, and have reduced risks for patients with comorbidities; however, they have limited application for correcting extensive damage. Examples of commonly used flaps and techniques include Esser flaps, Blascowicz, Ferris Smith, Mustardé, Converse, Stark, Juri and Juri, Zide and Schruder, and Kroll6,11,12.
Proper oral function and aesthetic results are the goal of oral cavity reconstruction, and skin grafts, local skin flaps, and free flaps are options for reconstruction of the oral mucosa. Tongue flaps are also an option, but may result in chewing and swallowing changes7,9.
Reconstruction of large facial substance loss is a surgical challenge and the combined use mucosal and local skin flaps is a good option for reconstruction of the total thickness of the cheek region, offering low morbidity and similar tissue.
