Objective: This study aims to evaluate the outcomes of surgical interventions for gigantomastia in at the obstetrics and gynaecology department of the Hôpital d'Instruction des Armées d'Akanda (HIAA). Patients and Methods: This was a prospective, descriptive study conducted from 1 June 2019 to 31 October 2022, Inclusion criteria comprised women who seeked consultation at HIAA due to unilateral or bilateral gigantomastia, have a benign primary or tumoral gigantomastia. Participants were required to consent to a minimum follow-up period of 6 months post-operation by the HIAA medical team and be available for telephone follow-ups beyond the initial 6 months. Results: The prevalence of gigantomastia was 1.05% (10/952). The mean age of the patients was 27 years. The mean BMI was 27.7 kg/m2. All patients wore a very large (≥D) cup size. The mean breast axis was 36.25 cm for straight breasts. The most frequently performed method was the inverted T with superior-internal flap (57%). The average weight of the operative parts was 1350 g for right breasts. Only one patient had delayed skin wound closure. Only one patient had a suture disunion. Regarding the plastic result, two patients were classified <<average result>> and the other two (50%) <<good result>>. Two patients report << very satisfied>>and the other two were satisfied. Conclusion: This study presented the preliminary results of an ongoing study at the HIAA. The inverted T technique with syuperomedial flap was the most commonly used, with few early complications. The plastic results after the 6th month are appreciable.
