Braimah-Taiwo et al New Classification System and Treatment Algorithm of Mandibulo-Maxillary Synostosis Related to Noma. Field Experience From Noma Children Hospital Sokoto, Nigeria

Abstract

Study Design This was a retrospective study at Noma Children Hospital, Sokoto, Nigeria, from January 2018 to December 2021. Objective The main objective of this appraisal was to present Braimah-Taiwo et al’s new classification system for mandibulo-maxillary synostosis secondary to noma and also to provide a guide to their treatment. Methods Noma with mandibulo-maxillary synostosis was the main inclusion criteria. Excluded were cases of acute noma and noma without mandibulo-maxillary synostosis. Data retrieved include demographics of patients and extent of bony ankylosis and mandibulo-maxillary synostosis. Results A total of 64 patients (30 (46.9%) males and 34 (53.1%) females) were managed. Ages ranged from 6 to 40 years with mean ± SD (18.2 ± 7.6) years. Regarding the new classification system of mandibulo-maxillary synostosis, 6 (9.4%) patients presented with Type 1 (Mild joint obliteration)±Soft tissue scarring, 24 (37.5%) presented with Type II (Total joint obliteration)±Soft tissue scarring, 21 (32.8%) presented with Type III (Coronoid, zygoma and maxilla) ±Soft tissue scarring, 4 (6.3%) presented with Type IV (Condyle, glenoid fossa, coronoid, sigmoid notch and zygoma) ±Soft tissue scarring, 7 (10.9%) presented with Type V (Condyle, glenoid fossa, coronoid, sigmoid notch, zygoma and pterygo-maxilla) ±Soft tissue scarring, while 2 (3.1%) patients presented with Type VI (condyle, glenoid fossa, coronoid, sigmoid notch, zygoma, pterygo-maxilla and the orbit) ±Soft tissue scarring. Conclusions Pattern of tissue destruction in noma patients is complex involving both soft and hard tissues. This new classification will guide surgeons in the effective management of these patients.
