Reconstruction of Noma Sequelae: A Surgical Treatment Algorithm Developed from Lessons from 210 Cases in Ethiopia.

Noma is an infectious disease affecting mostly children aged 0-10. Although it has almost completely disappeared from the Western world, it is still prevalent in many developing regions, mainly Africa's Sahel region. The infection behaves like a necrotizing fasciitis of the face, originating from the gums and progressively expanding into the cheek, nose, or eye regions. In an estimated 90% of cases, the disease is lethal as a result of systemic sepsis. For survivors, typical results are extensive defects of the cheek, nose, and periorbital and perioral regions. Due to the defects, extensive scarring is common, which leads to secondary problems such as growth alterations in an infant's skeleton due to inhibition and restraint of growth resulting typically in cicatricial skeletal hypoplasia. Other sequelae include trismus, partially caused by scarring or complete fusion between maxilla/zygomatic arch and mandible. The resulting overall disfiguring facial appearance results in patients being disabled and socially isolated. Methods: Facing Africa is a UK-based non-governmental organization that treats the secondary problems of Ethiopian noma survivors. Operations are performed in Addis Ababa by a visiting expert team. Postoperatively, patients are seen annually for years after the surgery. Results: This article discusses basic principles, goals, and a practical surgical algorithm for operating on lip, cheek, and oral defects, based on 210 noma patients who were operated on in Ethiopia over a period of 11 years. Conclusions: The suggested algorithm has proven to work for the Facing Africa team members and is considered shareware for all surgeons to use and benefit from.

Submental island flap - should we be worried about lymph node transfer? An anatomical and histological study.

The submental island flap has been increasing in popularity for both oncological and non-oncological reconstruction of the head and neck. However, the original description of this flap left it with the unfortunate designation as a lymph node flap. There has thus been significant debate on the oncological safety of the flap. In this cadaveric study the perforator system suppling the skin island is delineated and the lymph node yield of the skeletonised flap is analysed histologically. A safe and consistent approach to raising the perforator flap modification is described and the pertinent anatomy, and an oncological discussion with regards to the submental island perforator flap histological lymph node yield discussed. Ethical approval was received from Hull York Medical School for the anatomical dissection of 15 sides of cadavers. 6 x 4cm submental island flaps were raised following a vascular infusion of a 50/50 mix of acrylic paint. The flap size mimics the T1/T2 tumour defects these flaps would usually be used to reconstruct.The submental vascular anatomy, including length, diameter, venous drainage patterns, and the skin perforator system was documented. The dissected submental flaps were then histologically examined for the presence of lymph nodes by a head and neck pathologist at Hull University Hospitals Trust department of histology. The total length of the submental island arterial system, the distance from where the facial artery branches off from the carotid to the submental artery perforator entering the anterior belly of digastric or skin, averaged 91.1mm with anaverage facial artery length of 33.1mm and submental artery of 58mm. Vessel diameter for microvascular reconstruction was 1.63mm for the submental artery and 3mm for the facial artery. The most common venous anatomy drainage pattern was the submental island venaecomitantes draining to the retromandibular system then to the internal jugular vein. Almost half the specimens had a dominant superficial submental perforator allowing the ability to raise this as a skin only system. There were generally 2-4 perforators passing through the anterior belly of digastric to supply the skin paddle.73.3% (11/15) of the skeletonised flaps contained no lymph nodes on histological examination. The perforator version of the submental island flap can be safely and consistently raised with inclusion of the anterior belly of digastric. In approximately half the cases a dominant superficial branch allows for a skin only paddle. Due to the vessel diameter, free tissue transfer is predictable.Venous anatomy is variable and care needs to be taken when raising this flap. The skeletonised version of the perforator flap is largely devoid of nodal yield and on oncological review a 16.3% recurrence rate is equivalent to current standard treatment.

A Survey on Patient and Clinician Satisfaction With a Rapidly Implemented Telephone Consultation Service During the COVID-19 Pandemic.

AIM: The novel coronavirus pandemic presented unique challenges to healthcare organisations on an unprecedented scale. Due to the cessation of routine care, the Humberside Oral and Maxillofacial Surgery department implemented a telephone review service to maintain access to care. This survey study was conducted to gain feedback from patients and staff regarding the recently implemented remote telephone consultation service within the Humberside Oral and Maxillofacial Surgery unit. METHODS: A paper questionnaire comprising 16 questions was posted to 199 patients who underwent telephone review. A further questionnaire was sent via SurveyMonkey (Momentive Inc., San Mateo) to the clinicians involved. RESULTS: From 199 patients, 93 surveys returned were suitable for inclusion; 7 out of 12 staff replied to the survey. The results showed a high level of satisfaction with the service from both groups. There were also suggestions for future additions to the service, including use for new patient consultations, addition of webcam facilities and further streamlining of suitable cases for remote consultation. CONCLUSION: Our study demonstrated high patient and staff satisfaction with telephone consultations. It showed that over one third (37%) of patients were able to be discharged via telephone consultation, helping to maintain access, free up clinical resources and reduce the need for face-to-face clinical attendance, which has been vital throughout the coronavirus disease 2019 (COVID-19) pandemic. We now have suggestions for how this service can be implemented in the longer term within our department, including developing clearer guidelines for inclusion in the service and the possible benefit of video consultation.

Facing Africa: Describing Noma in Ethiopia.

Noma affects the most marginalized communities in the world, beginning as oral ulceration and rapidly progressing to orofacial gangrene. With a mortality rate estimated to be as high as 90% and with very few able to access treatment in its active phase, very little is understood about the disease. This retrospective review of patients treated by Facing Africa for deformity and functional impairment secondary to noma between May 2015 and 2019 highlights some of the difficulties encountered by those afflicted. Eighty new patients with historical noma defects were identified and were seen over the course of nine surgical missions, with notes providing valuable geographical, socioeconomic, and psychosocial information. The mean self-reported age of onset was 5 years and 8 months, with a median time of 18 years from onset to accessing treatment. Before intervention, 65% covered their face in public, 59% reported difficulty eating, 81% were unhappy with their appearance, and 71% experienced bullying. We aimed at emphasizing the significant burden, both psychologically and physically of noma, demonstrating the disparity between recent decades of progress in the well-being of Ethiopians in general and the access to health care and mental health support for some of those most in need.

Facial reconstruction in the developing world: a complicated matter.

Around the world there is a small industry of non-governmental organisations that provide health care in niche areas that cannot be met by national health care provision. One topic is facial deformity that can have a dramatic effect on quality of life. In this study we investigate the morbidity and outcome of a British surgical team working for a 2-week period in Ethiopia. Thirty-five patients who presented with facial deformities had 47 operations during a 2-week period. Data were recorded for a minimum of 3 weeks postoperatively. Operative techniques were classified as simple or complex. Postoperative complications were assessed and classified as major, intermediate, and minor. In addition, the character of each complication was recorded and the cause elucidated. After 3 weeks the clinical objectives had been achieved in 14/17 who had simple procedures but in only 5/18 who had complex operations (p=0.004). We conclude that complex procedures are technically possible within an under-privileged health care system but successful outcome depends on paying attention to multiple factors in patients' care and wound management. Early outcome studies may be a useful way to measure the quality of humanitarian surgical missions.
