Tracheo-gastric conduit fistula is an extremely rare but severe complication that is difficult to manage. Conservative care, esophageal or tracheal stent placement, or cutaneomuscular flaps have been suggested; however, no definite treatment has been proven. We report a case of tracheo-gastric conduit fistula that occurred after a minimally invasive radical three-field esophagectomy. Following the primary surgery, the diagnosis was made while evaluating the patient's frequent aspiration and coughing. Conservative management failed, and a surgical correction was undertaken to identify the multifocal mucosal defect and exposed tracheal ring. A sternocleidomastoid muscle rotation flap and subsequent Histoacryl injection into the remaining fistula were performed, and the fistula was successfully managed.

Maxillary defects are inherently complex because they generally involve more than one midfacial component. In addition, most maxillary defects are composite in nature, and often require bony support, as well as a mucosal lining for reconstruction. Therefore, midfacial bone and soft tissue defects present a unique challenge because they require a complex arrangement of tissues in a relatively limited space. This might be difficult to achieve only with free osteocutaneous flaps. The use of bone grafts allows greater flexibility in a reconstruction but is limited by graft resorption. We report a case of a patient reconstructed with a lateral arm free flap, iliac bone graft, sagital split ramus osteotomy for the reconstruction of a right maxillary defect zygomatico-maxillary defect caused by a zygomatico-maxillary malignant tumor resection.

Zygomaticomaxillary complex (ZMC) fractures account for a substantial proportion of trauma cases. The most frequent complications of maxillofacial fracture treatment are infections and soft tissue flap dehiscence. Postoperative infections nearly always resolve in response to oral antibiotics and local wound care. However, a significant infection can cause a permanent fistula. A 52-year-old man visited our clinic to treat an oroantral fistula (OAF), which was a late complication of a ZMC fracture. Postoperatively, the oral suture site dehisced, exposing the absorbable plate. However, he did not seek treatment. After 5 years, an OAF formed with a $2.0{\times}2.0cm$ bony defect on the left maxilla. We completely excised the OAF, harvested a piece of corticocancellous bone from the iliac crest, inserted the harvested bone into the defect, and covered the soft tissue defect with a buccal mucosal transposition flap. Although it is necessary to excise OAFs, the failure rate is higher for large OAFs (> 5 mm in diameter) because of the extensive defect in the underlying bone that supports the overlying flap. Inappropriate management of postoperative wounds after a ZMC fracture can lead to disastrous outcomes, as in this case. Therefore, proper postoperative treatment and follow-up are essential.

Recto-vaginal fistulas are difficult to treat due to their high recurrence rate. Currently, no single surgical intervention is universally regarded as the best treatment option for recto-vaginal fistulas. We present a case of recurrent recto-vaginal fistula surgically treated with a gracilis pull-through flap. The surgical goals in this patient were complete excision of the recto-vaginal fistula and introduction of fresh, vascularized muscle to seal the fistula. A defunctioning colostomy was performed 1 month prior to the present procedure. The gracilis muscle and tendon were mobilized, pulled through the freshened recto-vaginal fistula, passed through the anus, and anchored externally. Excess muscle and tendon were trimmed 1 week after the procedure. Follow-up at 4 weeks demonstrated complete mucosal coverage over an intact gracilis muscle, and no leakage. At 8 weeks post-procedure, the patient resumed sexual intercourse with no dyspareunia. At 6 months post-procedure, her stoma was closed. The patient reported transient fecal staining of her vagina after stoma reversal, which resolved with conservative treatment. The fistula had not recurred at 20 months post-procedure. The gracilis pull-through flap is a reliable technique for a scarred vagina with an attenuated recto-vaginal septum. It can function as a well-vascularized tissue plug to promote healing.

Background: The reconstruction of large full-thickness alar defects requires complex surgical procedures that are usually performed in two stages, with concomitant disadvantages in terms of patient trauma, surgical risk, and cost. This study presents a functional folded nasolabial island flap (FNIF) that can be used to repair large-sized full-thickness alar defects in a straightforward manner. Methods: This retrospective study included seven patients who received a FNIF for a full-thickness alar defect between January 2007 and December 2020. The FNIF is different from the conventional nasolabial flap in that it is folded and twisted to achieve nostril reconstruction with a satisfactory three-dimensional mucosal lining in a single stage. The cosmetic and functional results of FNIF were evaluated by both patients and physicians. Results: The age ranged from 51 to 82 years (mean, 65.6 years). The causes of the defects were squamous cell carcinoma, basal cell carcinoma, and trigeminal trophic syndrome. The nostril lining did not collapse, there was no hypertrophic scarring, and air movement through the nostrils on the flap side was normal. Overall, FNIF produced excellent aesthetic and functional outcomes, with minimal patient discomfort. There were no postoperative complications. Conclusion: Compared with existing reconstruction methods for large full-thickness alar defects, FNIF can easily achieve aesthetic and functional success in a single-stage procedure. It provides satisfactory results for both the patient and the surgeon.

Craniofacial cleft is a rare disease, and has multiple variations with a wide spectrum of severity. Among several classification systems of craniofacial clefts, the Tessier classification is the most widely used because of its simplicity and treatment-oriented approach. We report the case of a Tessier number 3 cleft with wide soft tissue and skeletal defect that resulted in direct communication among the orbital, maxillary sinus, nasal, and oral cavities. We performed soft tissue reconstruction using the straight-line advanced release technique that was devised for unilateral cleft lip repair. The extension of the lateral mucosal and medial mucosal flaps, the turn over flap from the outward turning lower eyelid, and wide dissection around the orbicularis oris muscle enabled successful soft tissue reconstruction without complications. Through this case, we have proved that the straight-line advanced release technique can be applied to severe craniofacial cleft repair as well as unilateral cleft lip repair.

The pectoralis major myocutaneous flap represents a major contribution to head and neck cancer reconstruction. Its advantages are improved viability, one-stage reconstruction, and carotid protection. The oropharyngeal defect especially tonsillar area reveals valley shaped one with loss of a wide mucosal area. Using pectoralis major myocutaneous flap to this defect is sometimes difficult due to its natural figure of bulkiness. This article reviews our experience with patients undergoing 14 pectoralis major myocutaneous flap in carcinoma of the tonsillar area. Complications and their incidences were I total loss, 3 marginal loss, 2 minor seperation of suture, I wound infection and 2 hematoma. Most of the complications did not require a second procedure for reconstruction. Bulkiness of the flap and gravity force to the upper suture line were thought to be causes of the complications. Modification of the flap design with bilobular figure was useful to reduce its bulkiness at the folding area. More stable suture around hard palate was needed to overcome seperation of the suture.

We evaluated a self-inflatable osmotic tissue expander for its utility in creating sufficient soft tissue elongation for primary closure after bone grafting. Six patients with alveolar defects who required vertical augmentation of >6 mm before implant placement were enrolled. All had more than three prior surgeries, and flap advancement for primary coverage was restricted by severely fibrosed scars. Expanders were inserted beneath the flap and fixed with a screw. After 4 weeks, expander removal and bone grafting were performed simultaneously. A vertical block autograft and guided bone regeneration and distraction osteogenesis were performed. Expansion was sufficient to cover the grafted area without additional periosteal incision. Complications included mucosal perforation and displacement of the expander. All augmentation procedures healed uneventfully and the osseous implants were successfully placed. The tissue expander may facilitate primary closure by increasing soft tissue volume. In our experience, this device is effective, rapid, and minimally invasive, especially in fibrous scar tissue.

Perianal Crohn's disease is a major problem that impair quality of life. This article reviews the current surgical treatment of Crohn's perianal fistula. Fistulotomy and loose seton are commonly used surgical methods for treatment of perianal Crohn's disease. Mucosal advancement flap and fibrin glue are used in this treatment, despite a lake of controlled trials. Fecal diversion is disturbingly high in complicated complex perianal fistula in Crohn's disease. Ligation of intersphincteric fistula and autologous or allogenic stem cells are new surgical procedures for treatment of Crohn's disease that need further studies. Treatment success might be improved by multimodal treatment and new surgical and medical treatment options.

A technical refinement for oral commissure reconstruction is presented. The oral commissure has an important role in oral sphincteric function. Once lost, the oral commissure is very difficult to restore and therefore, reconstruction of the oral commissure requires prevention of this function as well as prevention of microstomia. Trauma and tumor excisions are the most frequent reasons that will necessitate reconstruction of the oral commissure. Direct approximation of the wound margins after resection of the corner of the mouth could easily induce microstomia and difficulty in opening. Thus case presented here deals with distortion of noraml mouth angle and acquired microstomia due to burn and tissue deface following shotgun and explosive wounds. The a mucosal flap approach was used to rehabilitate a natural looking mouth angle showing satisfactory results function and esthetic wise.
