title: [Squamous cell carcinomas of the ear: factors of gravity and surgical treatment, about 30 cases].
abstract: BACKGROUND
  Squamous cell carcinomas (SCC) of the ear are known for their aggressiveness. The aim of this study was to investigate factors of gravity while freeing the therapeutic requirements.
  
  
  METHODS
  This is a retrospective study of 28 patients (30 ears) operated for SCC. The characteristics of the lesion, the presence of metastasis, treatment modalities and histologic findings were collected. Local recurrences and metastasis are identified with a mean follow-up time of 37months (17-110months).
  
  
  RESULTS
  The lesion size was less than 2cm in 19 cases (63.3%) and greater than or equal to 2cm in 11 cases (36.7%). Macroscopic resection margins were 5, 7 or 10mm. The resections were histologically incomplete in 4 cases (13%) requiring further surgery. Six cases had local recurrence (20%): three with pulmonary or lymph node metastases (10%) and one death (3.3%). In these 6 cases of recurrence, the surgical margins were 6.3mm on average, the initial lesion measured always greater than 2cm (100%). Three quarters of incomplete resections have recurrent despite a surgical revision in healthy margin.
  
  
  CONCLUSIONS
  Our study confirms the data of literature, namely the pejorative character of a lesion greater than 2cm and incomplete resection. The HAS recommendations seem minimal regarding the ear. In case of injury by more than 2cm and with a proximal location on the ear pinna, only amputation of the ear allows satisfactory cancer control.
