There are many different genetic syndromes in animals which result in deafness. Two major types of inherited deafness are known. The most common in animals, including man, is that in which there is early cell death of the neural epithelium. This is found in the cat, dog, mink, guinea pig, and mouse. The second type of inner ear deafness is associated with malformations of both the bony form of the inner ear and the neural epithelium. This type of deafness is that which is found in the kreisler mouse. It is also found in man, but appears to be less common than the early cell death in which there is no malformation of the bony labyrinth. This form of inherited deafness has been associated and may be secondary to genetic abnormalities of the developing CNS.

Injury to the facial nerve in rhytidectomy has been occurring in less than one percent of the cases, and a spontaneous return of function in more than 80 percent of these injuries has resulted within 6 months. With the introduction of the newer and more aggressive techniques of platysmal and subplatysmal flaps and SMAS dissections, the risk of injury to facial nerve branches is obviously increased. Though there has not yet been an increase in the facial nerve injuries reported, these techniques are still relatively recent additions to the face-lift operation-and usually they have been done by more experienced surgeons, taking more time and working under direct vision with a more careful dissection. More care is needed to prevent injuries. We discuss here the detailed anatomy of the muscular branches of the facial nerve, how to prevent injuries to them during rhytidectomy, and how to manage injuries when they do occur

There are several basic techniques for obtaining acceptable closure of the orbital defect following exenteration. The approach to reconstructing a socket in the method chosen should be the one that gives the best cosmetic result while not compromising the surgical excision and the possibility of cure. Few surgeons have attempted to correct the deformity of orbital exenteration so that an artificial eye can be worn. We have found that approximately 20% of those patients undergoing radical ablation of the orbit quality for simultaneous reconstruction of the eye socket. The technique of a cheek-eyelid-conjunctiva flap allows for immediate reconsturction of the eye socket and the fitting of a prosthesis.

A review of thread augmentation has added helpful points to the technique and given an opportunity to assess the long-range results. It is obvious at this stage that there is no panacea for the wrinkling process. Each technique has advantages and disadvantages. The simplicity and low complication rate of thread augmentation supports this appeal. It is reasonable to state that the full application of the concept of this type of augmentation has not as yet been realized with this ongoing principle. This technique has been found of value when used as a single procedure or in combination with blepharoplasty or rhytidectomy.

Fourteen case reports have been published in which "hot" nodules have been documented as carcinoma, with or without coexisting adenomas. The diagnosis of these lesions is difficult, since hot nodules usually represent benign disease. These carcinomas are not functional, but represent coexistence of a functional area or a malignant degeneration. Hot nodule carcinomas should be suspected in high-risk patients. A euthyroid, 31-year-old woman who, as a teenager, had radiotherapy for acne is reported. She was followed up with yearly scans for a hot nodule in the right lower lobe of her thyroid. When she was 36, a node was discovered in the right side of her neck, and carcinoma was suspected. Surgical excision revealed a papillary-follicular carcinoma adjacent to an adenoma with metastases to regional lymph nodes.

Radiotherapy is frequently employed in the management of head and neck neoplasia, either as an adjunct to surgery or as the sole treatment modality. Consequently, radiation alopecia--a well-known complication of high-dosage radiotherapy--is seen often. Longer patient survival, especially with earlier discovery of the malignancy and more refined treatment regimens, will provide the surgeon with the opportunity to treat radiation alopecia by means of the punch graft technique of hair transplantation. The technique is substantially similar to that employed in treating male pattern baldness, although the approach to the recipient and donor areas must be modified. A successful case report is documented and a modified approach is highlighted
