Closure of huge palatal fistula in an adult patient with isolated cleft palate: a technical note

Managing massive palatial defect secondary to palatoplasty failures: an in-depth analysis

PURPOSE OF REVIEW

Massive palatal defects resulting from palatoplasty failures arising from cleft palate repair complications present ongoing challenges in clinical practice. The purpose of this review is to provide up-to-date insights into aetiology, risk factors, surgical techniques, and adjunctive therapies, aiming to enhance the understanding of such complex cases, and optimize patient outcomes.

RECENT FINDINGS

Primary palatoplasty has fistula recurrence rates ranging from 2.4% to 55%. Factors such as cleft width, surgical repair method, and patient characteristics, influence the likelihood of failure. Classifications such as the Pakistan Comprehensive Classification and Richardson's criteria aid in assessing defects. Surgical options range from local flaps and revision palatoplasty to regional flaps (e.g., buccinator myomucosal, facial artery-based flaps, tongue flaps, nasal septal flaps) to free microvascular flaps. Alternative approaches include obturator prostheses, and acellular dermal matrix has been used as an adjuvant to multiple repair techniques. Hyperbaric oxygen therapy has emerged as an adjunctive therapy to enhance tissue healing.

SUMMARY

This comprehensive review underscores the intricate challenges associated with massive palatal defects resulting from palatoplasty failures. The diverse range of surgical and nonsurgical options emphasizes the importance of patient-centric, individualized approaches. Practitioners, armed with evidence-based insights, can navigate these complexities, offering tailored interventions for improved patient outcomes.

Pedicled buccal flaps as a backup procedure for intraoral reconstruction

BACKGROUND

Intraoral soft tissue deficiency and impaired wound beds are common problems after cleft and tumour surgery or after dental trauma. Frequently, limited defects are overtreated with extensive microvascular reconstruction procedures, but pedicled flaps remain useful, as they are simple to harvest, and they provide a reliable outcome. The buccal flap, first described in the 1970s, has been used for palatine lengthening in cleft patients over decades. In the following, we present an expanded indication in cases of palatal fistula, complex vestibulum, exposed bone in orthognathic surgery, and osteoradionecrosis.

METHODS

We conducted a retrospective chart review and report on all buccal flaps harvested in our department within the last 3 years with a follow-up period of at least half a year after flap surgery. Patients of all age groups and treatment indications in which a buccal flap was used were implicated in the evaluation.

RESULTS

Sixteen buccal flaps were performed in 10 patients. The median age at the time of surgery was 42 years, reaching from 12 up to 66 years. Fourteen buccal flaps were used for upper jaw or palatal coverage; two buccal flaps were used in the mandible. In terms of complications (four flaps; 25%), there were two partial flap failures, one wound dehiscence and one wound dehiscence. There were no failures of the remaining mucosal flap islands after pedicle dissection.

CONCLUSION

The buccal flap is a reliable and straightforward approach to challenging intraoral wound beds with soft tissue deficiency. We thoroughly discuss the additional indications for buccal flap surgery, describe the harvest technique, and provide strategies to prevent intra- and postoperative complications.

Use of a buccinator myomucosal flap and bilateral pedicled buccal fat pad transfer in wide palatal fistula repair: a case report

Primary palatoplasty for cleft palate places patients at high risk for scarring, altered vascularity, and persistent tension. Palatal fistulas are a challenging complication of primary palatoplasty that typically form around the hard palate–soft palate junction. Repairing palatal fistulas, particularly wide fistulas, is extremely difficult because there are not many choices for closure. However, a few techniques are commonly used to close the remaining fistula after primary palatoplasty. Herein, we report the revision of a palatal fistula using a pedicled buccal fat pad and palatal lengthening with a buccinator myomucosal flap and sphincter pharyngoplasty to treat a patient with a wide palatal fistula. Tension-free closure of the palatal fistula was achieved, as well as velopharyngeal insufficiency (VPI) correction. This surgical method enhanced healing, minimized palatal contracture and shortening, and reduced the risk of infection. The palate healed with mucosalization at 2 weeks, and no complications were noted after 4 years of follow-up. Therefore, these flaps should be considered as an option for closure of large oronasal fistulas and VPI correction in young patients with wide palatal defects and VPI.

Maxillary artery based flaps for oral cavity reconstruction, a review

BACKGROUND

There are different flaps based on the branches of the maxillary artery. Flaps based on the maxillary artery branches can be used for oral cavity reconstruction in selected cases, but there is lack of comprehensive review in this topic.

METHODS

A literature review was performed on Medline for maxillary artery based flaps and oral cavity reconstruction. Surgical techniques for each possible variant of maxillary artery based flaps and an example of each situation for oral cavity reconstruction is explained.

RESULT

Five variants of soft tissue flaps based on maxillary artery branches are presented. Some of them such as temporal flap, superiorly based masseter flap, palatal flap and posteriorly based buccinator myomucosal flap are famous flaps, while posteriorly based inferior turbinate flap is less noticed for oral cavity reconstruction. Nasoseptal and infraorbital based flaps are two other maxillary artery based flaps but have no role in oral cavity reconstruction.

CONCLUSION

Maxillary artery based flaps should be considered as an option especially in previously radiotherapy/surgically operated patients with facial vessels sacrifice.

Lateral Soft Palate Growth Deficiency: Case Report and Therapeutic Management

We report the case of a girl with syndromic cleft palate, probably as part of a first branchial arch syndrome, who was unique in having almost complete unilateral aplasia of the soft palate. Rather than using soft tissue transplants or a prosthesis, we pioneered the use of a modified Furlow technique, which proved to be simple to perform, effective, and safe.
