Abstract
OBJECTIVE: The primary aim of this study is to evaluate the impact of diagnostic procedures and treatment interventions performed at our medical institution on the final outcomes and survival rates of patients with iatrogenic and traumatic pharyngeal perforation (PP). MATERIALS AND METHODS: We reviewed the medical records of 36 patients with iatrogenic and trauma-induced PP who were treated at the Quaternary Medical Center of Otorhinolaryngology between 2010 and 2020. Comorbidities were classified according to the Age-adjusted Charlson Comorbidity Index (ACCI) scoring system, and postoperative complications were classified according to the Clavien and Dindo scoring system. RESULTS: Of the 36 patients, 15 (41.7%) were male and 21 (58.3%) were female. The median age was 73 years, and PP was typically diagnosed within one day. Notably, the perforation site was identified in the hypopharynx in 29 (80.5%) patients. The median ACCI score was 4, with the most frequent ACCI score observed being 5. During the treatment course, 17 patients (47.2%) experienced complications, with 9 of these patients experiencing grade IV complications according to the Clavien and Dindo classification. CONCLUSION: Our study showed that patients with hypopharyngeal perforations have an almost 42-fold higher risk of mortality during hospitalization compared to those with epipharyngeal or oropharyngeal perforations, though results are limited by the small sample size and the variable dates. Additionally, neurosurgery of the cervical spine, transesophageal echocardiography, and diverticular surgery emerged as procedures carrying the highest risk for pharyngeal perforations. Within our patient cohort, 4 patients (11.11%, all female) died during the treatment course.
