Pierre Adolph Grisel (1869 – 1959) was a French paediatric ENT surgeon

Eponymously remembered for his description of spontaneous, nontraumatic rotatory subluxation of the atlantoaxial joint following peripharyngeal inflammation or otorhino-laryngologic surgical procedures, or Grisel syndrome, in 1930

Very little is known about the life, times and works of Grisel the surgeon.

  • Born on October 21, 1869 in Paris
  • Chef de Clinique chirurgicale infantile
  • Died on October 24, 1959 in Paris aged 90

Medical Eponyms
Grisel syndrome (1930)

Spontaneous, nontraumatic rotatory subluxation of the atlantoaxial joint following peripharyngeal inflammation or otorhino-laryngologic surgical procedures (e.g. tonsillectomy, adenoidectomy). Occurs most commonly in the pediatric population

1830Charles Bell was the first to describe this syndrome

1930 – Grisel described and published cases of two children. It’s a rare clinical presentation which, in a febrile context, associates an acute torticollis linked to a contracture of the cervical pre- and peri-vertebral muscles due to an inflammation or infection of the nasopharynx or the retropharyngeal space, and this without any notion of bone pathology or trauma. It is accompanied by a rotatory subluxation of the atlas.

In his publication Grisel wrote:

The torticollis sometimes leaves behind a definitive vicious attitude. It is then one of its characterized, in its acute period, by the acuteness of the infection, of the deviation of the head and of the neck, of the evolution, and, in its chronic period, by a set of typical deformations, not progressive, but on the contrary appeared from the beginning with their degree and their definitive character.

A little girl of about ten years old, a few hours after a removal of tonsils or vegetations, at the beginning of an angina, is taken of high fever with pharyngeal pain and torticollis with extreme of torticollis with extreme deviation. After a few days, the temperature is normalized, the neck becomes deflects and palpation reveals the presence of retro-angulo-maxillary ganglions which are still painful. The cervical pain, high at the beginning, diminishes or disappears as well as the adenopathy, but a vicious attitude persists, all the more apparent as it is located in the sub-occipital region.

A real drama with rapid events took place there, which in a few days made a child a few days, of a child until then well conformed, a child whose deformity appears to all eyes. […] A spontaneous or postoperative infection […] determines in the retropharyngeal space an acute lymphangitis […] which, extending to the second lymph node, becomes visible and palpable in the visible and palpable in the internal jugular chain […].

The irreducibility is not due to to a simple snag that a rapid intervention could release, but to the permanent contracture at the beginning, to the fibrous retraction afterwards, which immobilizes the dislocated atlas and opposes its to its reinstatement by maintaining the abnormal approach of the occipital and the axis […]. It is the the abrupt dislocation of the atlas that makes, from the initial acute period, the torticollis definitive

We see in (i) the angle of the right articular surface of the axis, completely abandoned by the corresponding lateral mass carried back, the anterior and posterior tubercles of the atlas, (a) and (a’), and its left lateral mass (m) which has been driven out by compression and traction down and forward in front of the body of the axis. The part of the atlas not hidden by the base of the skull is only tinted in grey
