Tonsillectomy is known as one of the safest otorhinolaryngology surgery procedure. Rarely, it can lead to serious complications. Cervico-facial emphysema is an exceptional complication of tonsillectomy. Here we reported a case of post-tonsillectomy emphysema. Our objective was to emphasize the different characteristics of this entity and draw attention to the risk of potentially fatal respiratory complications. A 46-year-old healthy woman had a tonsillectomy because of recurrent tonsillitis. Four hours after extubation, she presented a subcutaneous emphysema under the left mandibular angle, slightly extended to the left cheek and left laterocervical region. An immediate cervicofacial CT scan showed a dissecting cervical emphysema of the left hemiface of moderate abundance that extended to the pre-vascular space of the superior mediastinum. The decision was to keep the patient hospitalized, to avoid forced glottic closure and to put her on prophylactic antibiotics. The further course was uneventful with respiratory state stability and emphysema's disappearance. Cervicofacial emphysema is a very rare but life-threatening tonsillectomy complication that may cause acute respiratory failure. Emphysema's main clinical characteristics are a non-tender cervicofacial swelling and crepitus. Post-tonsillectomy emphysema treatment is usually conservative. In cases of respiratory failure, it is necessary to secure the airway by intubation or tracheostomy. An important mediastinal expansion of the emphysema requires a thoracotomy. Cervicofacial emphysema is an unpredictable complication of tonsillectomy. Its prevention requires per-operative vigilance from both ENT surgeons and anesthetists. Moreover, early diagnosis and management are essential to avoid its potentially fatal consequences.
